Connection, can also be attached and be communicated by way of communication interface, for example, it is preferable to use USB interface.In this mode,
After the source code of program to be upgraded determines, encryption file is converted source code into by program file conversion equipment, and be saved in
Coupled program file storage device (such as program rod)., can after program rod completes the encryption file of reception ROMPaq
Directly to extract program rod from the USB interface of download program box, any one industrial control unit (ICU) to be upgraded is inserted afterwards
USB interface, when upgrading to controller firmware or program, program file storage device solves to the encryption file of storage
It is close, and executable program file is generated, the control program and circuit in program rod will send upgrade command from trend Industry Control,
And binary executable file destination is sent to by industrial control unit (ICU) by USB interface, realize single controller firmware or
Program upgrades.
For other industrial control unit (ICU)s, program rod can be continuing with other industrial control unit (ICU)s are upgraded, another
Preferably, the binary file of ROMPaq is transmitted by the bus between industrial control unit (ICU), is completed in bus
All controllers upgrading.
One exemplary application scenarios of system of the present invention are each hydraulic bracket controller in fully mechanized coal mining face
Upgrading.Subsurface environment is complicated, and communication bus bandwidth is relatively low, and may face complex working condition, is directly connected by program servers
Connect bus mode to upgrade hydraulic bracket controller, certain risk be present, in this case, the side of program rod can be passed through
Formula upgrades to a hydraulic bracket controller in working face, is then passed between hydraulic bracket controller by bus
Defeated and upgrading.
As shown in Figure 1, in fully-mechanized mining working, hydraulic bracket controller connects multiple sensors, such as infrared sensor, inclines
Angle transducer, pressure sensor etc., the firmware and program of sensor again may be by program rod or bus transmission model progress
Upgrading.
Exemplary, bus mentioned in the present invention can be that bus is serial for CAN, EPA or RS232
Bus.
In another exemplary embodiment, program rod directly can be connected with bus, send upgrade command and two and enter
File processed, realize the upgrading of controller firmware or program.
In addition, program rod can also include radio communication device, accordingly, controller also includes radio communication device, example
Such as in fully-mechanized mining working, staff or patrol officer the program rod with radio communication device can be taken take with oneself into
Enter working face to be overhauled or inspection, during maintenance or inspection, program rod passes through radio communication device and controller is carried out
Communication, upgrade command and binary file are sent, complete the upgrading of controller in working face.Under the embodiment, for control
The upgrading of device is actively operated without staff, can be completed simultaneously to all controllers in inspection or maintenance process
Upgrading.
Above-mentioned upgrade file conversion equipment is by file add items title to be upgraded, Program Type, product type, interface class
Type, channel number, whether issue, program version and MD5 check codes, regenerate encryption file.
Under controller normal operating conditions to be upgraded, program storage is connected with controller by CAN, program is deposited
Reservoir sends instruction control unit to controller and is switched to management program by application program, according to program rod internal information, it is determined that rising
Level Program Type, if issue etc., proceed by upgrading, accident power-off in escalation process, re-power then to break before
Point continues to upgrade, and is completed until the control of cascade all upgrades, controller restarts controller from trend upgrading opposite direction, so as to complete
Upgrade into program.
When controller is without application program, the controller is periodically sent from trend both sides inhales programmed instruction, by legal
Property judge after start suction sequence, until program all renewal complete, restart operation automatically.
Another aspect of the present invention, there is provided a kind of industrial control unit (ICU) programme upgrade method, referring to accompanying drawing 2, it shows
The workflow schematic diagram of industrial control unit (ICU) programme upgrade method of the present invention.
Specifically, upgrade method includes step：
Obtain program original document to be upgraded；
The original document is converted into encryption file, and is sent to program file storage device；
By the encryption file decryption and executable file destination is generated,
Program file storage device sends upgrade command to industrial control unit (ICU) by communication bus or communication interface and can held
Row file destination, the industrial control unit (ICU) is set to complete program upgrading.
System for managing program includes PC main frames, upgrade file management conversion software, upgrade file rod and downloaded under software, program
Carry device, program storage, controller and various sensors；Computer is using under upgrade file management conversion software, upgrade file
Load software, Program download are downloaded in program storage to file destination add items information and encryption information, and controller connects
Receive program storage information and complete designated program upgrading.
Above-mentioned upgrade file management conversion software by file add items title to be upgraded, Program Type, product type, connect
Mouthful type, channel number, whether issue, program version and MD5 check codes, regenerate encryption file.
Upgrade file is downloaded software and is connected by USB interface of computer with Program download, under program storage and program
Connected between load device by CAN, binary file is burnt in program storage.
Under controller normal operating conditions to be upgraded, program storage is connected with controller by CAN, program is deposited
Reservoir sends instruction control unit to controller and is switched to management program by application program, according to program rod internal information, it is determined that rising
Level Program Type, if issue etc., proceed by upgrading, accident power-off in escalation process, re-power then to break before
Point continues to upgrade, and is completed until the control of cascade all upgrades, controller restarts controller from trend upgrading opposite direction, so as to complete
Upgrade into program.
PC main frames can be connected by the fieldbus such as Ethernet or RS422 or CAN with controller, it is not necessary to program rod,
Directly controller system is completed to upgrade.
When controller is without application program, the controller is sent from trend both sides inhales programmed instruction, and starts suction sequence, directly
To program, all renewal is completed, and restarts work automatically.
When controller upgrading self-management program error, controller ROMPaq next time is caused to fail, short circuit transmission connects
Mouth communication cable, controller recover factory's backup management program automatically, mistake manages program before covering.
