Abstract


In order to solve some question such as different distribution region, wide distribution, large amount, device proving and incommodious maintainance of the present tumbling-type advertising machine, control system design scheme of advertising machine based on GSM information communication was developed in this thesis.As a proven communication mode, GSM short message has the advantage of less investment, low operating costs and wide information coverage. And it has the incomparable advantage of solving some system with wide monitoring coverage, not too high real-time demand and scattered monitoring collect point of advertising machine. This method can free operation maintenance personnel from heavy maintenance monitoring job, find and locate equipment failure in time, greatly reduce undesirable impact because of the system outage. GSM short message was used for a kind of data transmission mode. SIEMENS TC35i wireless module was used for monitoring advertising machine device by sending and receiving short message. These methods effectively solve the problem of remote monitoring equipment, have bigger promotion in performance than traditional tumbling-type advertising machine.This thesis mainly includes control system hardware design of tumbling-type advertising machine based on GSM information communication and implementation of GSM information communication. Firstly, hardware circuit design of systematic function and each functional module were introduced in detail, including the circuit design of human-computer interface, wireless module, brushless continuous current dynamo and clocking. Then the controlling difficulty of advertising machine in the process was solved: The vibration and noise which were generated by advertising machine in the process were reduced by the way of canvas moving, slow startand slow brake. The exact location information can be obtained by the way of self-checking and triphase Hall detection with triphase brushless continuous current dynamo, makes advertising machine canvas locate exactly, avoids producing deviation. Finally, the communication between STC12C5A60S2 processor and SIEMENS TC35i wireless module was implemented. When all kinds of signal and data were computed and handled by the processor, the corresponding failure warning message code by some encoded mode. Then PDU format data was produced by short message center number, purpose user number of receiving message, encoded mode, deadline. Then mobile phone user receives the short message by using AT instruction[AT+CMGS], or advertising machine receives command information and make corresponding actions form mobile phone user.At present, the basic functionality of advertising machine control system based on GSM information communication is implemented, the system can run normally, basically achieve the expected outcomes.
