Detection equipment and detection method for single-phase carrier module of intelligent meter

Abstract

The invention discloses detection equipment and a detection method for a single-phase carrier module of an intelligent meter. The detection equipment consists of a strong and weak current converting unit, an isolating circuit of an alternating current power supply, a pure 220V alternating current interface, an attenuation circuit and a detection circuit, wherein the detection circuit comprises a strong current interface, a microcontroller, a 'test start triggering' button at a triggering end, a relay control unit, a level detection unit, a reading controller communication interface, a weak current interface, a weak current interface protection unit and a sound and light alarm circuit connected at a judgment output end of the microcontroller, the reading controller communication interface is connected with the pure 220V alternating current interface through a reader, a control end of the sound and light alarm circuit is connected with an output end of the microcontroller, and the 'test start triggering' button is connected with the microcontroller. The equipment is used for detecting newly-mounted modules, and the modules which are detected to be normal are taken to sites to be mounted newly; modules to be sent to the sites to replace fault modules are also required to be detected, so that fault modules are prevented from being brought to the sites.

Description

technical field [0001] The present invention relates to a method and a detection device for judging the failure of the intelligent meter phase carrier module mainly aiming at the power carrier fault in the communication of the smart meter phase carrier module that occurs during the installation and use of the smart meter of the electric power enterprise, and particularly relates to a Intelligent single-phase carrier module detection equipment and detection method. Background technique [0002] Low-voltage power line communication (Power Line Communication) refers to a technology that uses the existing low-voltage power line network as a transmission medium to realize data transmission and information exchange. The characteristics of low-voltage power line carrier communication, such as wide distribution of transmission channels, no need for additional construction, plug and play, and convenient movement, are very attractive to meet people's needs. At present, they are widely...

Problems solved by technology

However, in the installation and promotion of smart meters, it is found that many smart meter signals cannot be returned normally. The current method is: go to the customer's site to use the copy controller and the handheld to cooperate, connect the copy controller to the power line, and collect the signal sent by the carrier module. , if the CC data is displayed in the handheld, the module can work normally, otherwise it will be judged that the module is faulty, and the module will be replaced on site and tested again until the signal is detected to be correct

This method requires repeated round trips, and it is easy to bring faulty modules to the site
