Abstract:

The design of the automatic data acquisition system for the multi-meter and hydraulic system can improve the efficiency of the meter reading, improve the work quality of the public institution and facilitate the users. At present, the design method of automatic data acquisition system of water and electricity multimeter is the use of GSM/GPRS network, design of water and electrical acquisition scheme and some programming examples. The system is inefficient and the system is not stable. To this end, a design method of automatic data acquisition system based on ATT7022B is proposed. This method USES data acquisition system master circuit, data acquisition system control circuit, data acquisition system interface, data acquisition system power supply circuit to form the hardware part of the system. Data acquisition circuit design is completed, according to measurement chip ATT7022B control circuit of the data acquisition system of warm moisture data collection, using K60 I/O pins to complete count, for gas data acquisition of ADC in available K60 power acquisition through multi-channel switch for switching current users, system of the power supply circuit with three groups of 5 v power to form a complete. The software part of the system USES the data collection system main program flow, and the process composition of the data collection as an example, the whole design of the data automatic collection system is realized. It is proved by experiment that the proposed method can realize the design of the automatic data acquisition system of the water and electric multi-meter, and improve the stability and reliability of the system.
