The design of interface module software:
Software is formed and function:
Interface module software is meant the program for the micro controller system operation that is solidificated among the micro controller system in-to-in FLASH, this software is finished with micro controller system C language, mainly by initialization module, break in service module, data processing module, data transmission blocks, parameter are provided with five parts of module and form.Finish following function:
(1) reception is from the information of system for recovering environmental protection shopping bag primary controller, comprise recovery information, failure message and facility information etc., information is stored among the FLASH according to certain form together with current time information, and information is packaged into the IP data packet, periodically utilizes the GPRS net to send to control center.
(2) receive Downlink Control Information, and when the request of receiving from the system for recovering environmental protection shopping bag primary controller, control information is sent to primary controller, thereby carry out Long-distance Control system for recovering environmental protection shopping bag from control center.
The software key points in design
What at first will consider during the software design is how to realize the MDB agreement, MDB is kind of a universal serial bus, all peripheral hardwares and primary controller adopt the master-slave communication mode, each peripheral hardware is prescribed unique address and instruction, request for primary controller must be responded at the appointed time, as do not have response, suppose that then peripheral hardware is not on bus.
Data transmission adopts 9600dpsNRZ, and its byte format is as follows:
Totally 11 of 1 Start Bit, 8 Data Bit 1Mode Bit, 1 Stop Bit
Start bit data bit pattern position stop bit
The pattern position is used to distinguish address and data byte, the pattern position is 1 presentation address, 0 expression data, block data during communication is made up of address byte, data byte, check byte or response byte, its limitation of length is in 36 bytes, wherein high 5 of address byte are used as the differentiation address, and hang down 3 is specific instruction, check byte must be at the end of block data, be address byte and data byte sum, the response byte mode position of peripheral hardware is 1, and the pattern position of last 1 byte of peripheral hardware data block transmitted is 1, the expression end of transmission.
Following several modes is roughly arranged:
Pattern one: peripheral hardware is in idle condition, sends reset instruction as primary controller, and peripheral hardware is responded, but free of data transmits.
Must follow the MDB agreement during software design, it is the master-slave communication pattern that microcontroller serial port is set, 9 bit data positions, when sending control information to primary controller, want the check byte CHK of computational data, and with the 9th position 1, promptly mode position 1 when sending, when the information that receives from primary controller, at first to carry out address validation, only when consistent, just deal with in the address, next with address byte and data byte and compare with the CHK byte that receives, as unanimity, then respond, otherwise will not respond, primary controller will resend this frame data behind certain hour.
After having realized the MDB agreement, the software design also must be considered the problem of the following aspects:
(1) how to guarantee data transmission credibility;
(2) how to guarantee data transmission security;
(3) how to guarantee GPRS communication link stability;
(4) how to guarantee the reliability of running software.
Aspect data transmission credibility, we take to store earlier the mechanism of afterwards transmitting to data, and when data transmission, adopt Handshake Protocol, control center is after receiving uplink data frames, should in the time of agreement, send echo message to interface module, if module is not received echo message in the time of agreement, then should continue to send this frame data, till receiving; Aspect data transmission security, adopt simultaneously and encrypt and authenticate two kinds of systems, transmit leg adds the authentication byte of calculating with the identifying algorithm of appointing earlier at the initial data frame end, and then total data is encrypted according to certain algorithm; Guarantee the GPRS data communication link unobstructed aspect, interface module time gap according to the rules sends test data frame to the center, come test link whether unobstructed, after test data frame is received by control center, should in time issue echo message, module is not received in continuous several times under the situation of center echo message, cuts off the current GPRS link automatically and also connects again; Aspect the reliability that guarantees running software, utilize micro controller system in-to-in WatchDog Timer that software is automatically reset when accident appears in operation, thereby guaranteed the normal operation of system.
