(3). technical scheme

The purpose of this utility model provides a kind of USSD communication-type wireless remote controller.Its cost is low, and monitored object is removable, measures accurately, can reduce taking of wireless channel.

For reaching above-mentioned purpose, the utility model is made up of industrial single-chip microcomputer, input channel, output channel, interface and module, it is characterized in that the P1.0 of industrial single-chip microcomputer, P1.1 interface are connected with RX_S0, the TX_S0 interface of GPRS module; P0.6, the P0.7 interface of industry single-chip microcomputer are connected with RX_H, the TX_H interface of GSM/GPRS communication module; P0.2, P0.3, P0.4, P0.5, the P2.3 interface of industry single-chip microcomputer are connected with SCK, MIS0, MIS1, MIS2, the MIS3 interface of flash memory device; P0.0, P0.1 interface and the I of industry single-chip microcomputer ²The SDA of C bus, SCL interface connect; P1.2, the P1.3 interface of industry single-chip microcomputer are connected with RX_S1, the TX_S1 interface of RS-232; P2.4, P2.5P2.6, P2.7, the P1.4 interface of industry single-chip microcomputer are connected with digital quantity input channel AS0, AS1, AS2, AS3, IN interface; 7,8,9,10,11,12,13,14 pin of industry single-chip microcomputer are connected with AIN0, AIN1, AIN2, AIN3, AIN4, AIN5, AIN6, the AIN7 interface of analog input channel; P3.0, P3.1, P3.2, the P3.3 interface of industry single-chip microcomputer are connected with digital quantity output channel interface.

The utility model is realized the industrial telemetry remote control owing to moving on the public network with gsm wireless with USSD, makes full use of the characteristics of wireless mobile public network wide coverage, has extended range of application of the present utility model to greatest extent.On-site data gathering of the present utility model and control terminal select for use the high-speed industrial chip microprocessor of 20MISP and high reliability GSM/GPRS communication pattern piece to constitute high reliability intelligent radio terminal.When communication is not smooth, it will preserve the information of uploading automatically, treat that the normal back of communication recovery benefit passes, thereby improve the overall reliability of system greatly.It is sent to Surveillance center's database to the spot sampling data in real time with the USSD transmission technology, and control command is delivered to intelligent terminal, realizes wireless telemetering remote information platform.In the coverage of GSM net, removable by the observing and controlling object, therefore the observing and controlling administrative staff can reduce taking of wireless channel whenever and wherever possible with the various running statuses and the information of GSM mobile handset or various web browser inquiry measurand.

Below in conjunction with accompanying drawing the utility model is described further.
