Embodiment 1

[0045] Such as figure 1 , figure 2 , according to the plant area diesel locomotive automatic control system provided by the present invention, comprising:

[0046] Module M1: Add a locomotive control cabinet in the locomotive control room, with built-in locomotive controllers and access modules, etc., so as to complete the automation transformation of the locomotive control system and equip it with a remote control equipment foundation.

[0047] Module M2: Establish a distance-speed model by fitting the speed and distance state curves of diesel locomotives under multi-level loads. At the same time, by comparing the real-time gear status of the train, the multi-level speed gear, multi-level brake pressure gear and coasting acceleration\deceleration empirical range values ​​are obtained, and the locomotive is customized according to the empirical operation steps of the locomotive operation under different working conditions. Expert library model. Then use the speed, distance...

Embodiment 2

[0054] Such as Figure 7 The locomotive control cabinet is installed in the locomotive control room, and the locomotive controller, display device, switch, access module, power module, emergency stop button and relay are built in the cabinet to realize the access to the locomotive signal and the control command. send, and remotely control the locomotive. Specifically: the upper platform uses the wireless network to issue operation instructions to the locomotive controller through the switch, and the expert system in the controller controls the locomotive operation instructions, and realizes the safety protection function of the locomotive according to the protection strategy. The command needs to issue control operations such as valve gear position, and realize the signal access and equipment control of various equipment of the locomotive through the signal access module, so as to realize the automatic control function of the locomotive; the display device is mainly used to di...

Abstract

The invention provides an automatic control system and method for a diesel locomotive in a factory. The system comprises a locomotive control cabinet, and a locomotive controller, a display device, a switch, an access module, a power module, an emergency stop button, and a related relay are arranged in the locomotive control cabinet; the automatic control system receives an upper operation instruction from the switch through a wireless network and sends the upper operation instruction to the locomotive controller, and an expert system in the locomotive controller analyzes the operation instruction to realize locomotive control; the access module is directly connected with the locomotive controller through a network; the display device is connected with the locomotive controller through the switch; the power supply module is connected with all equipment in the locomotive control cabinet and supplies power; the emergency stop button is directly connected with the locomotive controller through a hard wire; and the relay acts between the locomotive controller and a locomotive actuating mechanism. Automatic control of the locomotive is achieved through the vehicle-mounted PLC and the ground PLC, the labor cost of transportation operation is reduced, the safety risk of operation is reduced, and meanwhile the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic control system and method for a diesel locomotive in a factory area. Background technique [0002] At present, most of the iron and steel factories in China use diesel locomotives as power to realize the transportation of molten iron, steel and other materials in the factory. However, due to the inaccurate speed control of diesel locomotives and the inflexibility of external interfaces, the degree of automation of their operations is not high. At present, most locomotives in the factory area still use manual driving to achieve transportation operations. In order to realize the requirements of the unmanned development trend of the factory area, it is imperative to realize the automatic control of the transformation of the diesel locomotive. This system and related implementation plans are developed and designed based on this background. [0003] In order to...
