Problems solved by technology

But at present, the above-mentioned test operations are all carried out by manual spot checks, which not only requires more personnel to participate (testers are required in both the ground control center and the vehicle), but also has a large labor cost, and the test needs to collect a large number of samples, which takes time. Many, for the vehicles that have been put into use, the test can only be carried out after the vehicle stops operating in the early morning, which is very inconvenient to operate

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] see figure 1 As shown, the embodiment of the present invention provides a kind of automatic test platform for testing rail traffic signal system, comprises the service end (can be a computer) that is arranged on control center, is placed in the vehicle-mounted NTE (NetworkTestEquipment, network test equipment) in the train equipment) and CPE, the vehicle-mounted NTE is connected with CPE (Customer Premise Equipment, customer terminal equipment), and wireless communication is performed between the CPE and the server.

[0038] Wherein, the CPE is used to regularly send heartbeat packets to the server; the server is used to receive the heartbeat packets sent by the CPE, and after receiving the heartbeat packets, the on-board NTE and the vehicle-mounted NTE jointly complete the automated test by sending and receiving data;

Abstract

The invention discloses an automatic test platform and method used for testing a track traffic signal system, relating to the track traffic system test technical field. The CPE (Customer Premise Equipment) of the test platform is used for regularly sending heartbeat packets to a server side; the server side is used for receiving the heartbeat packets sent by the CPE, and completing automatic test with a piece of on-board NTE (Network Test Equipment) after receiving the heartbeat packets; in test, for a flow test, the server side and the NTE receive and dispatch test packets to realize upstream and downstream traffic test; for a packet loss ratio test, the server side and the NTE receive and dispatch data packets with packet sequence numbers to realize upstream and downstream packet loss ratio test; for a time delay test, the server side sends time delay packets to the NTE, and realizes time delay test through calculating the time difference when the on-board NTE returns the time delay packets. The automatic test platform and method can realize track traffic signal system automatic test, and have the characteristics of low human cost, short test time, high efficiency and convenient operation.

Description

technical field [0001] The invention relates to the technical field of testing rail transit systems, in particular to an automated testing platform and method for testing rail transit signaling systems. Background technique [0002] With the rapid development of urban rail transit trains, urban rail transit trains have played an important role in promoting economic and social development. Because urban rail transit has the characteristics of high speed, high density, and uninterrupted operation, the signal system that controls the operation of rail transit plays a vital role in ensuring the safe operation of rail transit and improving the passing capacity of rail transit. [0003] In order to ensure the safe and reliable operation of the signal system that controls the operation of rail transit, it is necessary to regularly test the delay, throughput, and packet loss rate of the system. But at present, the above-mentioned test operations are all carried out by manual spot c...
