Embodiment Construction

[0013] Such as figure 1 As shown, the locomotive signal part directly communicates with the train monitoring part through the electrical interface, or the locomotive signal part communicates with the train monitoring part through the electrical interface of the TAX box, so that the locomotive signal part can be purchased in real time to obtain various information of the train monitoring.

[0014] Such as figure 2 As shown, the locomotive signal collects the carrier frequency information sent by the train operation monitoring and recording device in real time to automatically determine the up and down status of the ground track circuit at the current locomotive operation site to determine the up and down status of the locomotive signal decoding, and then according to the The determined uplink and downlink lock and switch the decoding carrier frequency to perform accurate locomotive signal decoding and prevent the intrusion of adjacent line interference from affecting the locomotiv...

Abstract

The invention relates to a locomotive signal system which employs information of a locomotive running monitor and record device to automatically judge uplink and downlink and to lock and switch carrier frequency. The locomotive signal system automatically judges the uplink and downlink state decoded by locomotive signal through real-time collecting the information of carrier frequency of ground track circuits, which is corresponding to a locomotive running section and sent by the monitor and record device, and then locking and switching process is carried out according to the judged decoding carrier frequency of the uplink and downlink, thereby accurately decoding the locomotive signal and preventing the invasion of adjacent lines interference from influencing the decoding of the locomotive signal. The invention changes the selection of uplink and downlink of the locomotive signal from a traditional manual mode of 'people' controlling a 'machine' into an automatic mode of 'machine' controlling 'people'. The uplink and downlink automatic mode selection of the invention eliminates the work load of drivers generated from manual selection of the uplink and the down link in the traditional locomotive signal system, thereby avoiding serious consequences of train operation accidents resulting from mistaken on-lights of the locomotive signal caused by manually and mistakenly switching uplink and downlink switches.

Description

Technical field: [0001] The invention relates to a method for automatically judging upward and downward directions in a locomotive signal. Background technique: [0002] In order to ensure driving safety and prevent the intrusion of interference signals from adjacent lines, the locomotive signal system must have the function of decoding the uplink and downlink carrier frequency signals corresponding to the ground track circuit. In the current locomotive signal system, the choice of uplink and downlink carrier frequency requires manual control by the locomotive driver according to the operating section. This manual control method not only causes a great workload for the driver, but is also prone to wrong conversions, causing the locomotive signal to be turned on incorrectly, which will cause serious consequences in a driving accident. Summary of the invention: [0003] The purpose of the present invention is to realize a method for automatically judging the up and down in the loc...
