Description

Automatic detection platform for railway vehicle-mounted wireless communication equipment
Technical Field
The invention relates to the technical field of rail transit, in particular to an automatic detection platform for railway vehicle-mounted wireless communication equipment.
Background
Locomotive integrated radio communication equipment (CIR) has been operated on nationwide railways for more than 10 years, and the total number of CIRs of all-road equipment has exceeded 30000 by the end of 2018. The CIR warehouse inspection platform is arranged on the whole road at present, and is used for detecting various functions of the CIR when the motor train unit/locomotive goes out of the warehouse, so that the CIR warehouse inspection platform plays an important role in CIR detection and maintenance, but many links of the conventional CIR detection operation need manual intervention, and the automation degree needs to be further improved.
In recent years, the technical requirements for CIR have been changing: with the development of railway business, an application department puts forward a new functional requirement on the CIR; due to the planning and adjustment of national radio frequency, the existing 450MHz wireless train adjustment frequency of a head office is gradually recovered, and a CIR (channel radio identity) needs to realize a 400MHz digital wireless communication function; research and test are carried out on the next generation broadband mobile communication system of the railway, and the CIR can realize various existing services and new services in the system. Therefore, the China railway science research institute and the China railway general company sign a topic contract (number: 2016X 009-D) of the research on the key technology of the next generation mobile communication of railway-the research on the comprehensive radio communication equipment (CIR) of the new generation locomotive in 2016, and complete the research on the CIR of the new generation, including the establishment of the general technical scheme, the development of CIR prototype, test and verification, and the like.
At present, a new generation of CIR is about to start on-site test point application, and needs to be equipped with an automatic detection platform, when a motor train unit/locomotive goes out of a warehouse, the new generation of CIR is subjected to comprehensive automatic detection, including CIR self-checking test, dispatching communication voice detection, dispatching command detection, passenger train tail function detection, train protection alarm test and other items, and the CIR automatic detection level is improved. Therefore, it is necessary to develop research on the automatic detection technology and equipment of the new generation of vehicle-mounted wireless communication equipment as soon as possible to meet the requirement of field detection and maintenance operation of the new generation of CIR and ensure reliable application of the CIR.
At present, the following two detection methods are mainly adopted.
1. Technical scheme for detecting by CIR in-out warehouse detection table
After the bullet train/locomotive is put in storage, the detection personnel uses the CIR in-out storage detection table to perform functional detection on CIR equipment, such as self-detection, GPRS data, 450MHz data, passenger train tail function test, LBJ in-out storage detection, 450MHz same frequency call, 450MHz different frequency call, GSM-R call and the like, so that the normal operation of the equipment is ensured when the CIR is out of the storage. The CIR can also be remotely measured by a CIR in-out warehouse detection station on the ground to carry out self-detection single-item test.
The disadvantages of this solution are: the CIR in-out warehouse detection project requires detection personnel to perform detection step by step according to the operation flow sequence, and the automation degree is low. And only 1 CIR is supported for detection at the same time. Only self-checking, 450MHz data, GPRS data, passenger train tail function test and LBJ warehouse-in and warehouse-out detection can be automatically evaluated, voice detection of dispatching communication such as 450MHz same frequency call, 450MHz different frequency call, GSM-R call and the like must be qualitatively evaluated manually, and automatic quantitative evaluation cannot be achieved. The existing CIR and the new generation CIR can not be compatible for detection, field operators need to adopt a plurality of detection platforms to complete the detection of various vehicle-mounted wireless communication devices, and the detection efficiency is low.
2. Technical scheme for detecting by using double-mode train tail locomotive platform warehouse-in/out detection platform
After the locomotive is warehoused, detection personnel use the double-mode train tail locomotive platform warehouse-in and warehouse-out detection platform to perform functional detection such as self-detection, data testing (including GPRS data and 400MHz data), train tail function testing and the like on double-mode train tail locomotive platform equipment, and the normal operation of the equipment is ensured when the double-mode train tail locomotive platform is warehoused. And the double-mode train tail locomotive platform is remotely measured on the ground by using the double-mode train tail locomotive platform in-out and in-in detection platform to perform single self-detection test.
The disadvantages of this solution are: the dual-mode train tail locomotive platform warehouse-in and warehouse-out detection only supports 1 dual-mode train tail locomotive platform for detection. The existing CIR and the new generation CIR can not be compatible for detection, field operators need to adopt a plurality of detection platforms to complete the detection of various vehicle-mounted wireless communication devices, and the detection efficiency is low.
