Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

The state switching control method described in the embodiment of the present invention is applied to an Internet of Things device including a magnetic induction sensor. As shown in FIG. 1 , the method includes:

Step S110, when the energy-consuming component of the terminal is in the first state, detecting a signal triggered by a magnetic induction sensor due to a change in the distance from a magnetic field source;

Step S120, outputting, according to the signal, a switching control command for switching from the first state to the second state to the energy-consuming component of the terminal;

Wherein the first state is one of the dormant state and the working state, and the second state is the other of the dormant state and the working state.

The state switching control method uses a magnetic field source as a trigger source, and a magnetic induction sensor provided on the terminal as a trigger switch to realize switching between the terminal in a dormant state and an operating state. Since the magnetic induction sensor can be a passive component, it can adopt a lower Power consumption realizes switching between sleep state and working state.

Preferably, in the above step S110, the first state is a dormant state, wherein the step of detecting the signal triggered by the magnetic induction sensor due to the change of the distance of the magnetic field source includes:

Detecting a first signal triggered by the magneto-inductive sensor due to the proximity of a magnetic field source.

Wherein, step S120, according to the signal, outputting a switch control instruction for switching from the first state to the second state to the energy consumption component of the terminal includes:

According to the first signal, a switch control instruction for switching from a dormant state to a working state, that is, a wake-up control instruction, is output to the energy-consuming component of the terminal to wake up the terminal.

Based on the above method, when the terminal is in a dormant state, the terminal is awakened according to the trigger of the magnetic field source, thereby completing the non-periodic wakeup task. Compared with the multiple invalid periodic wakeups of the terminal in the prior art, the method of the present invention The purpose of effectively waking up the terminal can be achieved by using lower power consumption.

Preferably, when the first state is the dormant state and the second state is the working state, after the above step S120, the method further includes:

detecting a second signal triggered by the magneto-inductive sensor due to the distance from the source of the magnetic field;

According to the second signal, a switch control instruction, that is, a sleep instruction, is output to the energy-consuming component, so that the energy-consuming component enters a sleep state according to the switch control instruction.

Based on the above steps, the magnetic induction sensor set on the terminal is used as a trigger switch. In the sleep state, the proximity of the magnetic field source is used as a trigger to wake up the object terminal, and the distance of the magnetic field source is used as a trigger to make the terminal enter the sleep state again. The magnetic induction sensor is used as a switch to control the wake-up and sleep of the terminal, and when the magnetic induction sensor uses the approach and distance of the magnetic field source as the trigger for the wake-up and sleep of the terminal, it can be a passive component, so it can use lower power consumption to effectively wake up the terminal. the goal of.

In addition, preferably, after the above-mentioned step of outputting a switch control instruction for switching from the first state to the second state to the energy-consuming component according to the second signal, it further includes:

start timing after receiving the second signal;

After the timing reaches the preset time, a switching control instruction is output to the energy consumption component.

By adopting the above steps, that is, after receiving the second signal triggered by the magnetic induction sensor for a preset time, the dormancy control command is output to the energy-consuming component, so as to ensure the completion of the terminal data receiving and sending tasks.

In the above, the first state is the dormant state, and the second state is the working state. In the state switching control method described in the embodiment of the present invention, the magnetic field source is used as the trigger source, and the magnetic induction sensor provided on the terminal is used as the trigger switch to realize the terminal in the dormant state. And the specific process of switching between working states is described. Of course, the first state can be the working state, and the second state can be the dormant state. When the first state is the working state, step S110, the step of detecting the signal triggered by the magnetic induction sensor due to the change of the distance of the magnetic field source includes:

Detecting a second signal triggered by the magnetic induction sensor due to the distance of the magnetic field source.

In step S120, according to the second signal, a switching control instruction for switching from the working state to the sleeping state is output to the energy-consuming component of the terminal, that is, entering the sleeping state.

That is, through the above-mentioned manner, the terminal enters sleep mode through the change of the magnetic field intensity when the magnetic field source is far away. Of course, the method also includes:

detecting a first signal triggered by said magneto-inductive sensor due to the proximity of a magnetic field source;

According to the first signal, a switching control instruction for switching from the second state (sleep state) to the first state (awake state), that is, wake-up, is output to the energy-consuming component of the terminal.

The above process is described by taking the approach of the magnetic field source, the control terminal enters the working state from the dormant state, and the distance from the magnetic field source, and the control terminal enters the dormant state from the working state as an example. Of course, the above control process can also be reversed, that is, the control terminal enters the sleep state from the working state when the magnetic field source is close, and the control terminal enters the working state from the sleep state when the magnetic field source is far away. The specific working process can refer to the above description. This embodiment will not be described in detail here.

In addition, in the state switching control method described in the embodiment of the present invention, the terminal may be an Internet of Things device, and the energy consumption components of the terminal include a central processing unit CPU, a power conversion device, a memory, a display and other peripheral components.

On the other hand, the magnetic induction sensor installed on the terminal can be formed into a structure similar to a reed relay, including a tube body with two reeds inside, as shown in FIG. 2 , a schematic diagram of the internal structure of the magnetic induction sensor. Referring to Fig. 2, the magnetic induction sensor includes a tube body 1 filled with an inert gas (such as nitrogen, helium, etc.) or vacuum and two reeds 2 arranged in the tube body 1, preferably, the tube body 1 is made of glass material , The two reeds 2 are made of alloy material with high magnetic permeability, high electrical conductivity and low coercive force. The two reeds 2 are packaged in parallel inside the tube body 1 , have overlapped parts at the ends, and form contacts with a certain gap, forming normally open contacts. In addition, the tube body 1 is provided with lead wires 3 respectively connected to the two reeds 2 for realizing the state detection of the connection or separation of the two reeds 2 .

When the magnetic field source (such as a component with a permanent magnet) is close to the tube body, the ends of the two reeds 2 will induce magnetic poles with opposite polarities. Due to the opposite polarity of the magnetic poles and mutual attraction, when the attracted magnetic force exceeds the resistance of the reed, the separation ends of the two reeds 2 will attract; Under the action, the end points of the two reeds 2 are restored to the initial state.

The magnetic induction sensor with the above structure has the advantages of small size, small inertia, fast action and no power consumption.

In the state control method described in the embodiment of the present invention, by using the above-mentioned magnetic induction sensor, when the magnetic field source approaches, the control terminal enters the working state from the dormant state, and when the magnetic field source moves away, the control terminal enters the dormant state from the working state, the performance of the terminal The consumption part is in a dormant state, and a part with a magnetic field source is close to it, and the magnetic induction sensor is in the magnetic field generated by the magnetic field source. When the magnetic field strength is large enough, the magnetic attraction force generated by the two reeds 2 after being magnetized exceeds the reed. Resistance, the separation end points of the two reeds 2 will be attracted, and the two reeds 2 will change from the disconnected state to the conducting state. When the signal of the state change of the two reeds 2 is detected through the lead wire 3 , then a wake-up control signal can be output to the energy-consuming part to wake up the energy-consuming part of the terminal; when the part where the magnetic field source is set is far away, the magnetic field strength of the magnetic field where the magnetic induction sensor is located is small enough, and the elastic force of the two reeds 2 can be used to restore to The initial state, that is, the ends of the two reeds 2 are restored to separate, and the two reeds 2 are changed from the conduction state to the disconnection state. When the signal of the state change of the two reeds 2 is detected through the lead wire 3 , the dormancy control signal may be output to the energy consumption component, so that the energy consumption component of the terminal enters dormancy again.

Based on the above arrangement structure of the magnetic induction sensor, step S110 shown in FIG. When the two reeds of the magnetic induction sensor are in the open state, the signal triggered when the two reeds of the magnetic induction sensor changes from the open state to the closed state due to the proximity of the magnetic field source can be used as a trigger signal to wake up the terminal, based on this The signal can output switching control instructions for waking up to the energy-consuming components.
