Software of the server was developed by vc6 . 0 . the software of the server consists of the module of serial communication , the module of resolution , the module of management and the module of print . we use multithreading which can ensure synchronous running of all modules to develop the software of the server 服務(wù)器端的硬件部分由pc機(jī)和無線通信模塊ptr2000及外圍器件組成,軟件部分采用vc6 . 0實(shí)現(xiàn),由串口通信模塊、通信解析模塊以及前臺管理模塊及打印模塊組成;軟件實(shí)現(xiàn)部分由于采用了多線程技術(shù),使得系統(tǒng)的各模塊可以同步運(yùn)行。
