In a wide-range internet of things system, wireless data transmission and a wired network are often combined to form a basic internet supporting the internet of things. Compared with a wired network, especially a field industrial control network, the wireless network is frequently disconnected, the data delay is large, the packet loss ratio is high, and the network is not controlled more seriously. For an internet of things system needing remote control, the reliability of the remote control is seriously influenced by the characteristics.
In the control field, the fieldbus communicates with a plurality of devices, transmitting data for identification, monitoring, management. In the bus, if a plurality of devices transmit data at the same time, data collision is caused, data is distorted, and corresponding information cannot be transmitted. Therefore, in an internet of things system which covers a large range and utilizes a wireless network and a field bus, remote control signals are often lost, and may collide on a serial bus, so that control cannot be completed, even actions are disordered, and harm is caused. Meanwhile, the internet of things system comprises a plurality of software and hardware system platforms and products in multiple places, the working condition difference is huge, various uncertain events are easy to occur, and the reliability of control is affected, such as power failure, damage and the like.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The Internet of things equipment and the control end are communicated with each other. The internet of things device refers to information sensing devices and various action executing devices, such as infrared sensors, global positioning systems, laser scanners, motors, pumps, valves, robots and the like. The control end is used for sending an instruction for controlling the internet of things device to control the execution of corresponding actions of the internet of things device, such as: and starting and closing the Internet of things equipment.
Example one
Fig. 1 is a flowchart of a first embodiment of an internet of things device control method.
As shown in fig. 1, the method for controlling the internet of things device is executed on the control end side, and specifically includes the following steps:
step (1): the control end sends the control command of the Internet of things equipment to the command pool for caching, and command loss is avoided.
Step (2): and detecting the communication state of the equipment in the Internet of things, calling a corresponding control instruction of the equipment in the Internet of things cached in the instruction pool, and sending the control instruction to the equipment in the Internet of things.
And (3): and sending a state confirmation instruction to the Internet of things equipment, and further confirming the state of the Internet of things equipment according to whether a state confirmation instruction response of the Internet of things equipment is received to finally judge whether the control instruction of the Internet of things equipment is successfully executed.
In the step (3), if the control end does not receive the status confirmation instruction response of the internet of things equipment, further judging whether the sent status confirmation times are less than the preset times, and if so, resending the status confirmation instruction; otherwise, judging that the Internet of things equipment is disconnected or abnormal.
Therefore, whether the network transmission data is collided or distorted or not, the invention can correctly execute the instruction once by sending for many times. No matter whether the execution instruction of the Internet of things equipment is correct or not, the final state of the Internet of things equipment is correct by state confirmation and instruction sending.
In the step (3), if the control end receives the state confirmation instruction response of the internet of things equipment, further judging whether the state of the internet of things equipment is consistent with the expected state, and if so, judging that the control instruction of the internet of things equipment is successfully executed; otherwise, returning to the step (2).
If the expected state is not achieved after the command and the state are sent for multiple times, the next round of command sending and state confirmation can be carried out continuously, and therefore the traditional reliability of the Internet of things is improved.
Further, the method further comprises the step that after the control command of the Internet of things equipment is executed successfully, the control end deletes the corresponding control command of the Internet of things equipment in the command pool. Therefore, the instruction redundancy in the instruction pool is avoided, the instruction occupied space is saved, and the control efficiency of the Internet of things equipment is further improved.
Specifically, the method for controlling the internet of things equipment takes the control of a certain agricultural irrigation internet of things system as an example:
the agricultural irrigation Internet of things system comprises irrigation equipment positioned on a farmland irrigation field, an intelligent control cloud platform positioned in a telecommunication room, other accessory sensing equipment, transmission equipment and storage equipment. The system can control remote irrigation equipment through the cloud platform, and realize the operations of starting and stopping the irrigation equipment and the like. Wherein, the cloud platform is the control end.
When the irrigation equipment is remotely started or stopped, a starting or stopping instruction needs to be sent to the irrigation equipment through the cloud platform, so that remote control is realized. The start instruction is "start" and the stop instruction is "stop". The following describes the entire reliable control process by taking the start command as an example.
And (3) instruction caching flow: after the cloud platform sends a starting instruction request, the irrigation equipment identification code '12345' and the starting instruction form a complete instruction '12345 start'. The instruction "12345 start" is stored into the instruction pool. The new instruction '12345 start' is stored to the tail of the queue in the instruction pool for caching in the form of a queue.
And an instruction sending flow: the cloud platform sends the heartbeat packet to the irrigation equipment 12345, and if the irrigation equipment replies to the heartbeat packet, the irrigation equipment 12345 is on line. If the device is not on-line, the sending process is ended, and after the irrigation device 12345 is on-line, the command "12345 start" is started to be sent again. If the device is on-line, an instruction "12345 start" is sent to irrigation equipment 12345. The status confirmation procedure is initiated regardless of whether the cloud platform receives the instruction execution response from the irrigation equipment 12345.
And (3) state confirmation flow: the cloud platform sends a status query instruction "12345 state" to the irrigation equipment 12345, and then waits for receiving a status reply of the irrigation equipment 12345. If the status reply of the irrigation equipment 12345 cannot be received, resending the status inquiry command '12345 state' to the irrigation equipment 12345 until the status reply is received or the status inquiry times reach the preset times; if the number of status inquiries reaches a predetermined number, the equipment is disconnected or otherwise abnormal, the status confirmation process is stopped, and the command is re-sent by starting after the irrigation equipment 12345 is on line. If a status reply of the irrigation equipment 12345 is received, it is confirmed whether its status is the on status (the status in operation). If the state is the open state, the instruction is successfully executed, the instruction '12345 start' in the queue in the instruction pool is deleted, and the whole flow is ended. And if the state is not the opening state, restarting the instruction sending process.
In the method for controlling the internet of things equipment, firstly, an instruction cache flow is started, and an instruction is stored so as to prevent the system or the internet of things equipment from being in fault and losing the instruction; then starting an instruction sending process and sending an instruction; and finally, starting a state confirmation flow, and confirming that the instruction is successfully executed, so that the instruction can be sent to the Internet of things equipment after the equipment is on-line no matter whether the Internet of things equipment is on-line or not, thereby avoiding the instruction from being lost and improving the reliability of the control of the Internet of things equipment.
Example two
Fig. 2 is a schematic structural diagram of the internet of things device control end of the invention. As shown in fig. 2, the internet of things device control terminal of the present invention includes: the command sender and the state confirmer are respectively connected with the Internet of things equipment.
(1) The instruction transmitter is used for transmitting the control instruction of the Internet of things equipment to the instruction cache and caching the control instruction into an instruction pool of the instruction cache;
the instruction transmitter is further used for detecting the communication state of the Internet of things equipment, calling the corresponding Internet of things equipment control instruction cached in the instruction pool and transmitting the Internet of things equipment control instruction to the Internet of things equipment.
(2) And the state confirmer is used for sending a state confirmation instruction to the Internet of things equipment, and further confirming the state of the Internet of things equipment according to whether a state confirmation instruction response of the Internet of things equipment is received so as to finally judge whether the control instruction of the Internet of things equipment is successfully executed.
If the state confirmer does not receive the state confirmation instruction response of the Internet of things equipment, the state confirmer is also used for judging whether the state confirmation times of the state confirmer sent by the state confirmer are less than the preset times, and if so, the state confirmation instruction is sent again; otherwise, judging that the Internet of things equipment is disconnected or abnormal.
Therefore, whether the network transmission data is collided or distorted or not, the invention can correctly execute the instruction once by sending for many times. No matter whether the execution instruction of the Internet of things equipment is correct or not, the final state of the Internet of things equipment is correct by state confirmation and instruction sending.
If the state confirmer receives a state confirmation instruction response of the Internet of things equipment, the state confirmer further judges whether the state of the Internet of things equipment is consistent with an expected state, and if so, the state confirmer judges that the control instruction of the Internet of things equipment is successfully executed; otherwise, starting the instruction transmitter to continuously detect the communication state of the Internet of things equipment, calling the corresponding Internet of things equipment control instruction cached in the instruction pool, and transmitting the Internet of things equipment control instruction to the Internet of things equipment.
If the expected state is not achieved after the command and the state are sent for multiple times, the next round of command sending and state confirmation can be carried out continuously, and therefore the traditional reliability of the Internet of things is improved.
Specifically, the method for controlling the internet of things equipment takes the control of a certain agricultural irrigation internet of things system as an example:
the agricultural irrigation Internet of things system comprises irrigation equipment positioned on a farmland irrigation field, an intelligent control cloud platform positioned in a telecommunication room, other accessory sensing equipment, transmission equipment and storage equipment. The system can control remote irrigation equipment through the cloud platform, and realize the operations of starting and stopping the irrigation equipment and the like. The cloud platform comprises an instruction transmitter, a state confirmer and an instruction buffer.
When the irrigation equipment is remotely started or stopped, a starting or stopping instruction needs to be sent to the irrigation equipment through the cloud platform, so that remote control is realized. The start instruction is "start" and the stop instruction is "stop". The following describes the entire reliable control process by taking the start command as an example.
And (3) instruction caching flow: after the command transmitter receives the request of sending the starting command, the irrigation equipment identification code '12345' and the starting command are combined into a complete command '12345 start'. The instruction "12345 start" is stored to the instruction buffer. The instruction buffer is a queue, and stores a new instruction "12345 start" to the end of the queue.
And an instruction sending flow: the command transmitter sends a heartbeat packet to the irrigation device 12345, and if the irrigation device replies with a heartbeat packet, the irrigation device 12345 is on-line. If the device is not on-line, the sending process is ended, and after the irrigation device 12345 is on-line, the command buffer starts the resending of the command. If the device is on-line, the command transmitter sends a command "12345 start" to irrigation equipment 12345. The status confirmation procedure is initiated regardless of whether the command transmitter receives a command execution response from the irrigation equipment 12345.
And (3) state confirmation flow: the status validator sends a status query "12345 state" to the irrigation equipment 12345 and then waits to receive a status reply from the irrigation equipment 12345. If the status reply of the irrigation equipment 12345 cannot be received, resending the status inquiry command '12345 state' to the irrigation equipment 12345 until the status reply is received or the status inquiry times reach the preset times; if the number of state inquiry times reaches the preset number, the equipment is disconnected or is abnormal, the state confirmation process is stopped, and the command buffer starts the resending of the command after the irrigation equipment 12345 is on line. If a status reply of the irrigation equipment 12345 is received, it is confirmed whether its status is the on status (the status in operation).

EXAMPLE III
Fig. 3 is a flowchart of another method for controlling the internet of things device according to the invention. As shown in fig. 3, the method for controlling the internet of things device is described from the control end and the two sides of the internet of things device, and specifically includes the following steps:
step (1): the control end sends the control instruction of the Internet of things equipment to the instruction pool for caching, so that the instruction is prevented from being lost, and the instruction is prevented from being lost;
step (2): the control end detects the communication state with the Internet of things equipment, calls a corresponding Internet of things equipment control instruction cached in the instruction pool and sends the Internet of things equipment control instruction to the Internet of things equipment; the Internet of things equipment responds after receiving the corresponding instruction;
and (3): the control end sends a state determination instruction to the Internet of things equipment, the Internet of things equipment responds after receiving the state determination instruction, and the state determination instruction response is fed back to the control end;
and (4): and the control terminal further confirms the state of the Internet of things equipment according to whether the state confirmation instruction response of the Internet of things equipment is received or not so as to finally judge whether the control instruction of the Internet of things equipment is successfully executed or not.
In the step (4), if the control end does not receive the status confirmation instruction response of the internet of things equipment, further judging whether the sent status confirmation times are less than the preset times, and if so, resending the status confirmation instruction; otherwise, judging that the Internet of things equipment is disconnected or abnormal.
Therefore, whether the network transmission data is collided or distorted or not, the invention can correctly execute the instruction once by sending for many times. No matter whether the execution instruction of the Internet of things equipment is correct or not, the final state of the Internet of things equipment is correct by state confirmation and instruction sending.
In the step (4), if the control end receives the state confirmation instruction response of the internet of things equipment, further judging whether the state of the internet of things equipment is consistent with the expected state, and if so, judging that the control instruction of the internet of things equipment is successfully executed; otherwise, returning to the step (2). If the expected state is not achieved after the command and the state are sent for multiple times, the next round of command sending and state confirmation can be carried out continuously, and therefore the traditional reliability of the Internet of things is improved.
The method further comprises the step that the control terminal deletes the corresponding Internet of things equipment control instruction in the instruction pool after the Internet of things equipment control instruction is executed successfully.
In the method for controlling the internet of things equipment, firstly, an instruction cache flow is started, and an instruction is stored so as to prevent the system or the internet of things equipment from being in fault and losing the instruction; then starting an instruction sending process, sending an instruction to a control end, and responding by the Internet of things equipment; and finally, starting a state confirmation flow, and confirming that the instruction is successfully executed by the control end, so that the instruction can be sent to the Internet of things equipment after the equipment is on-line no matter whether the Internet of things equipment is on-line or not, thereby avoiding the instruction from being lost and improving the reliability of the control of the Internet of things equipment.
