Data concentrator of intelligent meter reading network system

Abstract

The invention discloses a data concentrator of an intelligent meter reading network system. The data concentrator comprises a shell and an inner circuit located in the shell, wherein the shell comprises an upper shell (1) and a lower shell connected with the upper shell (1); a screw (8) is arranged at each of the four corners of the upper shell (1) and is used for fixedly connecting the upper shell (1) and the lower shell; a lug boss (2) is arranged at the upper part of the front surface of the upper shell (1); the lug boss (2) is provided with a liquid crystal display screen (3), an operation indication lamp (5) and a key (6); a data transmission interface is arranged on the side face of the lower shell; the inner circuit comprises a microprocessor, a memory, a clock, an interface driving circuit, a wireless communication circuit, a wireless communication antenna and an encrypted circuit; the microprocessor is connected with the clock, the interface driving circuit, the wireless communication circuit and the encrypted circuit; the encrypted circuit is connected with the memory; the interface driving circuit is connected with the data transmission interface. The data concentrator can be communicated with lower equipment.

Description

technical field [0001] The invention relates to the technical field of data collection, in particular to a data concentrator for an intelligent meter reading network system. Background technique [0002] With the rapid development of science and technology, more and more new technologies are applied to people's daily life. For example, water meters, gas meters and electric meters used to require manual meter reading, which not only consumes a lot of manpower and material resources, but is also prone to errors. Now it has been realized. Remote meter reading is simple, efficient and accurate. As one of the core devices in the automatic meter reading system, the data concentrator is responsible for realizing functions such as command transmission and remote communication of the remote centralized meter reading system. However, the existing data concentrator does not have a communication module, so it cannot communicate with the lower equipment or the meter reading module. Co...
