Embodiment Construction

[0007] The hardware part of the system realizes the communication between the single-chip microcomputer and the 4 meters and the GPRS module. The data communication between the single-chip microcomputer and the 4 meters is carried out through the RS-485 bus. The single-chip computer in the terminal is 77E58. A serial port, three 16-bit timers.

[0008] The selection of this single-chip microcomputer mainly considers the following aspects:

[0009] 1. Because it needs to communicate with the GPRS module (motorola G18 module) and the meter reading module, it is necessary to use a single-chip microcomputer with 2 serial ports.

[0010] 2. Because this system needs to collect information from the meter reading module, and perform related data calculation, processing, storage and output in the single-chip microcomputer, and the real-time requirements of the whole system are relatively high, so the processing speed is relatively fast. Single-chip microcomputer, after receiving the ...

Abstract

The invention provides a meter reading control method for a family meter, comprising an electricity meter and control device; the invention is characterized in that a control system adopts a mode of collaborative work of multi computer chips, and a method of integrating the system and an electric circuit into a specialized SOC chip for convenient control and operation. the invention adopts a wireless meter reading and can be networked with a banking system, realizing the automatic transfer of costs, thereby the invention has the advantages of cost save, easy assembly and convenient maintenance, and can be applied to reading family meters such as electric meter and water meter, etc.; therefore, the invention is particularly suitable for occasions where the space span is large, the manual reading is inconvenient and the real time requirement of the data is high.

Description

technical field [0001] The invention relates to an instrument control method, in particular to a meter reading control method for household meters. Background technique [0002] At present, the power consumption of users is displayed by the electric meter, and each house is equipped with electric meters. The electrician will read the meter from door to door on time, calculate the electricity consumption, and collect the payment. This process is very cumbersome and brings trouble to the meter reader. And sometimes the phenomenon of reading the wrong meter also occurs, and the user brings losses. Contents of the invention [0003] Aiming at the defects of the prior art, the invention provides a practical meter reading control method for household meters. [0004] In order to achieve the above object, the present invention takes the following measures to achieve: [0005] A meter reading control method for household meters, including electric meters and control equipment, i...
