Electricity collection terminal function tester

Abstract

The invention relates to an electricity collection terminal function tester which is especially suitable for the electricity collection and maintenance of a power system. The electricity collection terminal function tester is structurally characterized in that a power supply is connected with an electric shock protector; an AC (alternating current) converter, a switch, a computer, a printer and an electricity centralizer are respectively connected with the electric shock protector; both the AC converter and the electricity centralizer are connected with a watt-hour meter protocol simulator; the switch is respectively connected with the electricity centralizer and the computer; and the electricity centralizer and the computer are respectively connected with a telephone set. According to the communication protocol specification of the electricity collection terminal and the support condition of a testing terminal to a plurality of communication manners and communication protocols, the electricity collection terminal function tester can be used for verifying the correctness of the flow, analyzing and processing the feedback information of the collection terminal to form an integral terminal testing report, assisting test operators to test the function of the electricity collection terminal and also has a certain fault analysis effect.

Description

technical field [0001] The invention relates to a function tester, in particular to a function tester for a power collection terminal, and is especially suitable for power system power collection and maintenance. Background technique [0002] The electricity collection terminal is the basic equipment of the electric energy metering automation system. It plays a connecting role in the electric energy metering collection system. It is responsible for collecting, processing, and storing various data on the electric meter. Provide data, which is the basis for ensuring the integrity and accuracy of power data. With the expansion of the scale of the electric energy metering system, it is usually necessary to connect multiple collection terminal devices and watt-hour meters. Although the statutes of each equipment manufacturer support the DL / T645 and IEC60870-5-102 statutes, since the statute is only a framework, no specific details are stipulated; and in the specific implementati...
