It can be understood that the low-voltage centralized meter reading system is an important component of a metering automation system or an information acquisition system, and is an information component system with numerous users, complex application environment and great technical difficulty. The low-voltage centralized meter reading system consists of a master station server, a communication channel, a collection terminal (a concentrator and remote control equipment) and a collector. The master station server is the brain of the low-voltage centralized meter reading system, is responsible for data transmission, application, processing analysis and information interaction of the whole system, ensures the safety of the system, and is a complete computer management system comprising software and hardware. The communication channel links the master station server, the acquisition terminal and the acquisition device, is a medium for information interaction, and is divided into uplink communication and downlink communication according to a transmission mode. The acquisition terminal (data acquisition and remote control equipment such as a concentrator) is equipment for realizing data acquisition, data management, data bidirectional transmission, forwarding and execution of control commands of the acquisition equipment, and is core equipment for detecting and controlling the low-voltage centralized meter reading system.

According to the embodiment, the traditional collector incapable of wireless communication can be upgraded and modified, so that a new sampling sensor 10 does not need to be purchased again, and the cost is further reduced; meanwhile, information acquired by a sensor is not directly output to the master station server by the wireless communication module 20, so that the mobile communication network is stable in communication and fast in signal transmission; the problem that the communication information of the original power line carrier communication is mistakenly transmitted due to power interference is solved.
