Wireless portable BTM detector

Abstract

The invention provides a wireless portable BTM detector. The wireless portable BTM detector comprises a trackside device and a hand-held device; the trackside device is mainly used for receiving and measuring the radio-frequency energy sent by a BTM antenna, measuring the distance between the BTM antenna and a steel rail surface, and also simulating to send an FSK responder message signal, including simulating of different FSK energy magnitudes; a server is established outside the detector, and in data interaction with a BTM host recorder and the detector; the hand-held device is used for sending a test instruction to the server, generating a report and displaying a test result; and connecting lines and chargers of the trackside device and the hand-held device are placed in a portable box.Due to the wireless detector, which can be taken away by being placed in the portable box, networking can be conveniently realized; the test result is automatically uploaded to the server; due to a wireless sending module configured on the BTM host, wireless data interaction with the server is realized; the detector is adaptive to all kinds of existing BTM host interfaces; and field application is greatly convenient.

Description

technical field [0001] The invention relates to the application field of railway signal equipment detection, in particular to a portable BTM detector, a BTM device for wirelessly dumping data and a detection method. technical background [0002] The Transponder Message Transmission Module (BTM) is mainly composed of a BTM host and a BTM antenna. The main function is to transmit an activation energy signal to the ground transponder through the BTM transmitting antenna, and receive the uplink signal sent by the transponder through the receiving antenna. The text data is sent to the on-board train control equipment. Therefore, the identification and diagnosis of BTM equipment abnormalities, and regular maintenance and testing are particularly important. [0003] At present, the overhaul and maintenance of BTM equipment installed on site is mainly through visual inspection, power-on self-inspection, and for the message sending and receiving function, the operator uses the transp...

AI Technical Summary

Problems solved by technology

None of the above can quantify the main functions and performance of BTM equipment, including message receiving and sending functions, detection function of radio frequency energy emitted by BTM antenna, BTM decoding sensitivity detection, etc.

[0004] The following problems exist in the current BTM detection device: 1. Need to receive the message data from the interface (hereinafter referred to as the B interface) of the BTM host and the vehicle-mounted equipment. To the B interface, the ground equipment that sends the data is analyzed. After the detection is completed, it is necessary to reconnect the BTM equipment to the vehicle equipment cable

There are great installation risks in such an operation, including incorrect cable connection, looseness, damage to equipment, etc.; 2. All equipment is integrated in the inspection vehicle, and the operator needs to go down to the maintenance ditch when performing on-site inspection. For the operator There will be problems with electromagnetic radiation, and there will be dangers of strong electricity; 3. The transmitted FSK message signal cannot adjust the amount of energy it transmits, that is, it cannot fully measure the sensitivity of BTM equipment to receive radio frequency energy and decode it; 4. Equipment networking cannot be realized, that is, the test results cannot be automatically backed up to the server or the Internet, which is not convenient for data storage and subsequent analysis; 5. The test system is relatively large and does not have good portability; 6. Some measuring devices pass Manually shrink the fixing device to determine the center point of the BTM antenna. The transmitting antenna cannot be completely positioned at the geometric center point of the BTM antenna through manual positioning.
