Rate-limiting control integrative information system for railway

Abstract

The invention provides a rate-limiting control integrative information system for a railway, which comprises an electric rate-limiting signal board, a wireless communication network, a control center, a wireless rate-limiting receiving device arranged in the front of a locomotive and a locomotive running monitoring and recording device (LKJ) arranged on the locomotive, wherein a wireless communication network module receives a rate-limiting instruction transferred by the control center and sends the basic information, working state and locomotive execution feedback information of the electricrate-limiting signal board to the control center; and the wireless rate-limiting receiving device receives the rate-limiting information sent by the electric rate-limiting signal board, and transmitsthe rate-limiting information to the LKJ. The rate-limiting control integrative information system has the advantages that the transparent and high-efficiency transfer of rate-limiting information ina global network are realized, and a dispatching center can acquire the feedback whether the locomotive receives the rate-limiting information or not, and the safety of railway running routes is ensured.

Description

【Technical field】 [0001] The invention relates to a train operation monitoring and recording system, in particular to a railway speed limit management and control system. 【Background technique】 [0002] The train operation monitoring and recording device (LKJ) is an important guarantee equipment to ensure the safe, efficient and reliable operation of trains. After years of development in our country, there are relatively mature JK-93 and LKJ2000 models, and they are widely used in national trains. , belongs to the monitoring device of vehicle data mode. [0003] Before driving, it is necessary to write information such as the speed limit, signals, bridges, tunnels, curves, station coordinates, and the distance between signals, the length of the station to the departure line, etc. Unpredictable factors such as stock lanes and trains heading to other branch lines. There are many problems such as inconsistent system and data format in the LKJ equipped nationwide, which brings...

AI Technical Summary

Problems solved by technology

[0009] Disadvantage 1: Although the Ministry of Railways currently has a strict management process for the speed limit of public works, there are still loopholes in human factors

[0015] After the above three guarantee links failed, the train did not make proper adjustments according to the changed speed limit information on the ground, which led to the accident

[0016] Disadvantage 2: At present, the speed limit signal boards inserted in the public works section are all wooden or iron speed limit signal boards, which cannot be visually managed

[0017] 1. It is impossible to track its specific location in real time

[0018] 2. Unable to change the speed limit content in a timely manner

[0019] 3. The dispatch center cannot obtain whether the train perceives the speed limit information correctly and executes it correctly

[0020] Disadvantage 3: The dispatch center cannot obtain the status and results of train speed limit execution in real time

[0021] The existing LKJ system cannot timely feed back the execution status and results of LKJ according to the pre-stored driving data to the dispatching console, resulting in a huge series of differences between the existing driving status and the actual demand status, and this series of differences is what leads to major accidents potential cause of

[0022] Disadvantage 4: It is impossible to realize the network-wide transparency of speed limit information and LKJ working status

[0023] 1. The dispatch center cannot actively obtain the working status and execution results of LKJ

[0024] 2. In case of emergencies, the dispatch center cannot fully adjust the LKJ system in real time

[0025] 3. The whole network cannot realize the real-time flow and transparency of speed limit information
