Intelligent electric energy meter detection module based on bluetooth communication and 485 communication and detection method

Abstract

In allusion to a series of problems that the product structure is complicated, the cost is high, the volume is large, the mass is heavy, the usage is not convenient, etc., which are caused by that the conventional intelligent ammeter reading equipment need to execute an ESAM standard, the present invention provides an intelligent ammeter operation condition detection module based on bluetooth and 485 communication and a detection method. An intelligent electric energy meter detection module comprises a CPU module, a 485 communication module, a bluetooth communication module, a USB-to-485 conversion connection line, an indicating lamp, a power supply module, a charging / discharging control module, a shell and a switch button. The detection method comprises seven steps. The beneficial effects of the present invention are that: by adopting a 485 communication mode to carry out the data interchange with an intelligent ammeter, an ESAM authentication link is avoided, at the same time, by adopting the bluetooth communication module to carry out the data interaction with an intelligent mobile phone, the operation information of the intelligent ammeter is transmitted to the intelligent mobile phone to analyze.

Description

technical field [0001] The invention belongs to the technical field of smart electric energy meter detection, and in particular relates to a detection module and a detection method of a smart electric energy meter based on bluetooth communication and 485 communication. Background technique [0002] At present, in the operation and maintenance of electric power consumption, handheld devices are usually used to obtain the operating condition data of smart meters through infrared communication. Only the built-in ESAM module can perform data interaction with the smart meter, which limits the use of the handheld to a certain extent. And the current special-purpose handheld device is inconvenient to operate and expensive. Contents of the invention [0003] Aiming at a series of problems such as complex product structure, high cost, large volume and heavy weight, and inconvenient use caused by the existing smart meter reading equipment that needs to implement the ESAM standard, ...
