Locomotive short-distance wireless communication control system

Abstract

The invention provides a locomotive short-distance wireless communication control system. A driver control unit is communicated with region control units by a short-distance wireless manner; all signal acquisition devices and execution devices on a locomotive are nearby divided into all control regions; each control region is internally provided with one region control unit; the region control units in the control regions are used for receiving signals transmitted by the signal acquisition devices by lead wires and transmitting control instructions to the execution devices; a driver controls the generated driver control instructions to be transmitted to a locomotive control center by the driver control unit; the locomotive control center is used for transmitting execution instructions to all the region control units; and all the region control units are used for transmitting the signals transmitted by the signal acquisition devices in the regions to the locomotive control center. According to the locomotive short-distance wireless communication control system, the quantity of solid lead wires is greatly reduced and locomotive fault links are reduced; holes which are used for wiring and are formed in all steel structures are reduced; reconnection control does not need solid connection wires; and the portable driver control unit can realize under-locomotive operation.

Description

technical field [0001] The invention relates to a locomotive short-distance wireless communication control system, which belongs to the technical field of railway locomotive manufacturing. Background technique [0002] In the prior art, the control of the locomotive is to transmit the signal sent by the driver's operation controller to the locomotive microcomputer or other control unit through the wire, and then the control unit sends control instructions to the locomotive control contactors, relays, etc. through the wire. Control the operation of the locomotive, or the signal of the controller is directly transmitted to each control contactor, relay, valve and other control components through the wire to achieve the purpose of controlling the locomotive. The signals collected by the sensors all over the locomotive are also transmitted to the locomotive microcomputer through wires. There are a large number of these control lines and signal lines, and the wiring has the foll...

AI Technical Summary

Problems solved by technology

[0003] 1. There are too many intermediate nodes, so there are many fault links

[0004] 2. After long-term use, the wires are prone to insulation aging or damage and short-circuit to the ground, resulting in burning of electrical parts, and serious fires

[0005] 3. Many wires need to pass through various partition walls or underframes inside the locomotive, causing too many holes in the steel structure of the locomotive, which has a great impact on the sealing performance and sound insulation performance of the locomotive.

[0006] 4. The locomotive can only be controlled in the driver's cab, and the off-board control required under certain circumstances cannot be realized

[0007] 5. The wire connection is complicated when the locomotive is reconnected
