Most in the market gsm modules are all supported the AT command set of GSM07.07 regulation.Utilize the serial line interface of gsm module, controller module sends the AT order and by the gsm module feedback information, just can realize control gsm module transmitting-receiving note to gsm module.It is as shown in table 1 that gsm module receives the related AT instruction of short message.
Table 1
| The AT instruction | Functional description |
| AT+OFF | Shutdown is also restarted |
| AT+CMGF＝1 | Selecting messaging format is the TEXT pattern |
| AT+CMGR＝* | Read * bar short message |
| AT+CMGD＝* | Delete * bar short message |
| AT+CMGL＝0 | List and do not read SMS message |
Braille printer function: receive the control command that controller module is sent, return corresponding feedback information, equipment Ready and equipment B usy are arranged and receive three kinds of feedback informations of print data, equipment Ready shows that the ready and data buffer zone of printer has living space, can receive short message content from controller module, equipment B usy shows that printer is printing and the data buffer zone is full, can't receive short message content, receive print data and show that the braille printer successfully receives the short message content that will print from controller module; Convert buffering area character GB2312 coding to the braille matrix of printed dots according to the braille dictionary, braille dot lattice printing is as a result come out, and the content that printing is finished is removed from buffering area.The braille dictionary is to be stored in the Chinese characters in common use national standard codes in the braille printer chip and the table of comparisons of braille word lattice, is specifically designed to output braille literal.
Controller module function: control gsm module access network and SMS receiving; Receive note and remove draft from gsm module; Short message content is become the GB2312 coding from the Unicode code conversion; Control braille printer prints short message content.
Controller module is realized by mcu programming, is the center of whole invention, the operation of control whole system.
Controller module and gsm module and controller module and braille printer adopt the serial asynchronous communication interface, and communication speed can be set, and is generally 9600bps.When adopting this RS232 cable mode to connect, reliability of data transmission is better.The RS232 interface mode connects, be connected with gsm module and braille printer with level shifting circuit by the serial line interface integrated circuit, circuit is fairly simple, and related chip comprises single-chip microcomputer such as 89C52 and level transferring chip MAX232, the interface circuit that right and wrong are usually seen.
51 series monolithics generally have only an IEEE Std serial highway, and controller module of the present invention all is to be connected by the RS232 interface with braille printer and gsm module, so do many serial extended units with numerical control analog switch CD4052, wiring as shown in Figure 2.
CD4052 has 4 independently channel data selectors, has two inputs of A, B and one to forbid importing INH, selects a pair of in 4 pairs of passages by 4 kinds of binary combination states of A, B.
Serial data frame format between gsm module and controller module and controller module and the braille printer module: Frame is made up of 1 Bit start bit, 8 Bit data bit and 1 Bit position of rest.8 Bit data bit sequences be low level (LSB) in proper order preceding, high-order (MSB) after.1 Bit start bit is always low level, and 1 Bit position of rest is always high level.Do not have transfer of data (RXD or TXD) on the connection, be necessary for high level during line idle.
Whole system is the center with the controller module, adopts inquiry-response mode to carry out communication.Be that controller module is given an order to gsm module or braille printer, feed back after gsm module and the braille printer fill order.
Controller module is as shown in table 1 to the AT order that gsm module sends, data encoding format is: the 1st byte at every turn transmitting data sequence is the beginning byte, second byte is for sending the total bytes of data, do not comprise own and CRC length and beginning end byte, last the 2nd byte of transmission data sequence is necessary for 8 the polynomial cyclic redundancy detection check of divisor sign indicating numbers (CRC8) that CCITT (Consultative Committee on International Telegraph and Telephone) recommends, and last byte is an end byte.Gsm module is same as described above to the feedback information coded format that controller module sends.
The order that controller module sends to the braille printer has two kinds of querying command and print commands.First kind of order is used for inquiring about printer modes, and second kind of order makes printer prints braille note under the printer ready state.Data encoding format is: the 1st byte at every turn transmitting data sequence is the beginning byte, second byte is for sending the total bytes of data, do not comprise own and check byte length and beginning end byte, last the 2nd byte of transmission data sequence is check byte, computable number is according to district's byte and remove carry as check results, and last byte is an end byte.The braille printer is same as described above to the feedback information coded format that controller module sends.
In gsm module or braille printer transmission order, can start timer at controller module, if timer surpasses certain hour, controller module is not received feedback information, just retransmit order, retransmit the certain number of times of order and all do not receive feedback, just thinking that controller module loses with command object is connected, and provides warning prompt.And do not carry out this mechanism when the GSM feedback information for gsm module and braille printer, acquiescence packet loss control device module is retransmitted order.
Short message time and date under the Text pattern is ASCII character, can directly read, and only needs to convert the Unicode sign indicating number of Chinese character part in the content to GB.Owing to there is not linear transformation relation one to one between Unicode coding and the GB2312 coding, to adopt look-up method to realize with the conversion of controller module control routine, therefore, need set up the table of comparisons of changing between Unicode sign indicating number and the GB2312 sign indicating number.
Controller module, sends and reads new short message instruction with after gsm module is connected by serial ports: " AT+CMGR=* ", when extracting short message, judge its content encoding earlier, if ASCII character then need not conversion and directly reads; Otherwise, search its corresponding Chinese character GB2312 sign indicating number by look-up table, realize the conversion between different coding, flow path switch is as shown in Figure 3.
Should adopt binary chop when look-up table is searched coding, its worst number of times of searching is log
2(n+1), the length n of the table of comparisons is approximately 7000, so the worst number of times of searching is about 13 times.That is to say that a Chinese character code conversion is relatively searched and can be finished through 13 times at most, controller module can be finished in real time.
As Fig. 4, controller module workflow: choose with the serial ports of gsm module to be connected, the inquiry gsm module is obtained the feedback whether note is arranged, if received the note feedback information, send the short message reading order to gsm module, and will change GB2312 coding from the short message content that gsm module imports in case of necessity into and deposit the data buffer zone in, simultaneously to the gsm module note that deletion obtains of giving an order; Choose with the serial ports of braille printer and be connected, if the note that the data buffer zone remains to be printed, then inquire about the braille typewriter state, if braille typewriter feedback Busy state information, wait for that then certain hour inquires about the braille typewriter state again, if braille typewriter feedback Ready state information is then taken out a note from the data buffer zone, be sent to the braille printer prints by serial communication.More than be flow process in the one-period, constantly repeat this process during controller module work.The controller module data buffer zone adopts round-robin queue's data structure to realize, makes things convenient for the access and the counting of note data and saves when being necessary the buffer pool size needed efficient expense that increases.
After start powered on, program was moved in principal function, and single-chip microcomputer and gsm module carry out initialization respectively.The initialization of single-chip microcomputer comprises serial ports working method, baud rate is set, and initializing variable parameter and flag bit.The gsm module initialization comprises that restarting, select messaging format is the TEXT pattern, opens serial ports interruption preparation reception data.After initial work is finished, can enter controller module periodic duty flow process, realize the printing of braille note.
