The invention belongs to the field of device measuring and control, and provides a device and a system of wireless remote measuring and control. The device comprises a short message data transmission unit, an input and output detecting and control unit and a global system for mobile communication (GSM) transmission unit. The short message data transmission unit is used for receiving a decoding short message order and transmitting to the input and output detecting and control unit, and meanwhile sending the code of report data. The input and output detecting and control unit is used for executing an order sent by an upper computer or sent through mobile phone short messages and sending a report to the upper computer or a mobile phone. The GSM transmission unit is is used for monitoring a sensor device and transmitting management data, receiving the data, transmitted by a GSM network, of the input and output detecting and control unit, and transmitting the received data to a database in a wired mode. According to the device and the system of the wireless remote measuring and control, short messages with the function of transmitting the data in real time are manufactured to a data communication system which transmits various detection and monitor data signals and control orders. Therefore, the device and the system of the wireless remote measuring and control can by widely used for remote monitoring, positioning and navigation and personal communication terminals and the like, and the input of manpower and material resources and errors in work are reduced.
Description
technical field [0001] The invention is applicable to the field of equipment measurement and control, and in particular relates to a wireless remote measurement and control device and system. Background technique [0002] GSM system is a digital mobile communication system based on TDMA (Time Division Multiple Access) multiple access mode. The GSM system consists of mobile station, base station subsystem, network subsystem, A interface and U m The short message service is the only service in the GSM system that does not need to establish an end-to-end service channel. The point-to-point short message is an alphanumeric string in any form, which is transmitted through the digital control channel. Occupies the independent dedicated control channel (SDCCH) when idle, and the information rate is 782b / s; occupies the slow associated control channel (SACCH) when talking, and the channel rate is 383b / s. In order to avoid too long time delay and excessive load on these vying acce...
