Problems solved by technology

However, there are many types of plug-ins, a large number, and strong professionalism, and their maintenance and management will bring a lot of manpower and material resources; in order to solve this problem, it is urgent to develop an automatic test system to evaluate power protection plug-ins verify
[0003] The traditional automatic test system is mainly designed for specified types of plug-ins, and the compatibility is not good. When the company's products are updated, the hardware and software of the automatic test system need to be re-modified; It can support batch testing of plug-ins, which is difficult to implement

Embodiment 1

[0041] This embodiment introduces a batch automatic testing system for plug-ins of power protection devices. The whole system can be simplified into three layers: control layer, communication layer, and equipment layer. figure 1 The equipment layer is mainly composed of a series of tested chassis and test plug-ins; the chassis stores plug-ins belonging to this type of device, and can store multiple plug-ins (the number is determined according to the size of the chassis). Taking chassis 1 as an example, all the plug-ins of type A are loaded in the chassis. In order to realize the unified control of plug-ins, a fixed IP address is assigned to the network ports of each plug-in, and they belong to the same network segment, and n blocks of plug-ins correspond to The IP address of the device is X.X.X.1~X.X.X.n in sequence, and the plug-ins in the range of 1-n belong to the A-type device, that is to say, the IP address can uniquely identify the device model and the plug-in model, such...

Embodiment 2

[0055] This embodiment provides a method for testing a power protection device plug-in batch automatic test system according to any one of Embodiment 1, which is applied to the control layer, including:

[0056] By reading the IP address table module, enter the mapping table of IP and plug-in information;

[0057] By scanning the plug-in module of the chassis, obtain the IP address that can be communicated, and display the plug-in information and the number of existing plug-ins at the device layer according to the mapping relationship table between IP and plug-in information;

[0058] Transmit one or more of test program and script information to each plug-in in turn through Ethernet;

[0059] Send a unified contract message to the device layer to start the test program inside each plug-in, wherein the device layer returns the test information and test results to the control layer in real time;

[0060] Obtain test information and test results returned by the device layer, an...

Abstract

The invention discloses a power protection device plug-in batch automatic test system comprising a control layer comprising a test process configuration unit, a test result display module and a data analysis module which are connected in sequence; the equipment layer comprises a tested case and plug-ins, and a plurality of plug-ins are stored in the tested case; the communication layer comprises a plurality of switches which are mutually cascaded, the switches and the plug-ins are in one-to-one connection through network ports, and the switches are further connected with the control layer through the Ethernet to form a local area network. The whole system comprises a control layer, a communication layer and an equipment layer, has certain expansibility and compatibility, can better solve the problems of various plug-ins and large test quantity for enterprises, and reduces certain manpower and material resource consumption.

Description

technical field [0001] The invention relates to a batch automatic testing system for plug-in power protection devices, which belongs to the technical field of power protection devices. Background technique [0002] With the country's emphasis on power grid construction and the increase in capital investment, power protection equipment has shown a diversified development trend, and the replacement cycle of substation protection equipment has become shorter and shorter. Based on this, manufacturers need to develop and manufacture different types of functional plug-ins to meet the needs of various application scenarios. The power protection device is mainly composed of a series of internal plug-ins. The correctness of the plug-in function directly affects the expected operation of the device. Therefore, it is particularly important to do a good job of testing and functional verification of the plug-in. However, there are various types of plug-ins, a large number of plug-ins, a...
