The invention relates to a test apparatus oriented to intelligent measuring communication. The tester comprises a shielding cabinet used for containing intelligent measuring equipment; a signal isolating separator is arranged in the shielding cabinet; a broadband antenna used for receiving and transmitting high-frequency electromagnetic waves is also arranged in the shielding cabinet; the broadband antenna is installed in the shielding cabinet; the other end of the broadband antenna is connected with a shielding cable which is used for outputting a high-frequency signal; the shielding cable is connected with a plurality of program-controlled remote control attenuators which are also uniformly controlled by a console; the shielding cable is also connected with a signal source and a spectrum analyzer, is coupled with a controller and is connected with the console through a communication wire; and the console is used for sending a communication command to the intelligent measuring equipment through the controller for controlling to read data in the intelligent measuring equipment or write the data into the intelligent measuring equipment. The invention provides a pre-test way for establishing an intelligent measuring system and can reduce the risks for the selection of system types, construction and investment.
Description
technical field [0001] The invention relates to a test and test device for smart metering communication, which is a test device for network access detection and evaluation of smart metering products with communication modules. technical background [0002] With the pilot and official use of smart energy meters, a large number of smart energy meters with communication functions will enter the power grid for operation, and conduct necessary performance tests on a large number of smart devices such as energy meters, collectors, and concentrators of many companies entering the grid , It is still blank at present, especially the power supply bureau or power supply company has no applicable detection test device. Developing a test platform with reasonable structure, appropriate investment, convenient use, comprehensive detection, and effective evaluation of smart metering electric energy meters and remote acquisition devices will help power supply companies to evaluate products wh...
