Description

The wheel rim of locomotive automatic oil spout and the device of blowing a whistle automatically

Technical field

The utility model relates to a kind of wheel rim of locomotive automatic oil spout and the device of blowing a whistle automatically.

Background technology

At present, locomotive oil spout and blowing a whistle by driver's personnel operation.In more complicated location, to blow a whistle often, driver's labour intensity is forgotten greatly and easily, the problem of occur the wheel rim oil spout simultaneously, being forbidden the time of blowing a whistle.Therefore, according to the position of locomotive operation wheel rim automatic oil spout and blowing a whistle automatically on request, what train was saved grease, traffic safety, minimizing railway security accident is very significant.

Summary of the invention

The purpose of this utility model provides a kind of wheel rim of locomotive automatic oil spout and the device of blowing a whistle automatically, and it comprises: microcontroller circuit 1, RS485 communicating circuit 2, keyboard circuit 3, data memory circuit 4, indicator light circuit 5, relay output circuit 6 and the power circuit 7 of dc supply is provided for the each several part circuit;

Described microcontroller circuit 1 is made of a micro controller system and peripheral component thereof, described keyboard circuit 3 links to each other with the keyboard interface end of micro controller system, data memory circuit 4 links to each other with the address end with the corresponding data end of micro controller system by bus, the data communication port of described micro controller system links to each other with the corresponding interface of RS485 communicating circuit, finishes and reception from the operational factor of locomotive TAX2 cabinet or monitor recording device; Indicator light circuit 5 is connected with the corresponding control signal mouth of the micro controller system of microprocessor 1 by bus; Relay output circuit 6 is connected with the corresponding control signal mouth of micro controller system by bus.

This device adopts expansion plugin in the TAX2 cabinet, wheel rim of locomotive automatic oil spout or blow a whistle automatically when being implemented in through bend and tunnel or appointed place.On the basis based on stable monitored control system, adopt communication control circuit industrial grade, that have strong anti-interference ability combination with it.Having the wheel spray ground data software for editing of blowing a whistle simultaneously can revise parameter such as kilometer post and be fit to the needs that different Railway Environment require to reach.

The specific embodiment

As shown in Figure 1, it comprises: microcontroller circuit 1, RS485 communicating circuit 2, keyboard circuit 3, data memory circuit 4, indicator light circuit 5, relay output circuit 6 and the power circuit 7 of dc supply is provided for the each several part circuit;

Described microcontroller circuit 1 is made of a micro controller system and peripheral component thereof, described keyboard circuit 3 links to each other with the keyboard interface end of micro controller system, data memory circuit 4 links to each other with the address end with the corresponding data end of micro controller system by bus, the data communication port of described micro controller system links to each other with the corresponding interface of RS485 communicating circuit, finishes and reception from the operational factor of locomotive TAX2 cabinet or monitor recording device; Indicator light circuit 5 is connected with the corresponding control signal mouth of the micro controller system of microprocessor 1 by bus; Relay output circuit 6 is connected with the corresponding control signal mouth of micro controller system by bus.Use light-coupled isolation to handle at the relay drive end.

The whole control system is just under the co-operative control of microcontroller circuit, utilize the 89C55 of atmel corp treater in-to-in FLASH to deposit program, after powering at first CPU will carry out self-check program, normal start back CPU constantly intercepts the monitoring that 485 buses send by 485 isolating device MX1480 information such as kilometer post, speed, distance.Constantly with leave that the bend of depositing in the 27C040 data chip begins and the ending message comparison in, find qualified data, then according to being that bend or tunneling data send the oil spout of corresponding 110V bend or the tunnel control signal of blowing a whistle.

As Fig. 3, Fig. 4, described keyboard circuit 3 is made of testing button, and its mouth is connected with micro controller system Keyboard Control input end; Indicator light circuit 5 is accepted lamp 1B, morse signal light 2A, testing button lamp 2B, the 110V I that blows a whistle output 4A, the 110VII that blows a whistle output 4B, breakdown of equipment indicator lamp 5B, I end indicator lamp 6A, II end indication 6B by power light 1A, data, and its interface end is by bus and micro controller system corresponding connection respectively; Described RS485 communicating circuit 2 is made of RS485 communication IC and peripheral circuit thereof, and its receiving end links to each other with transmitting terminal with the corresponding receiving end of micro controller system respectively with sending end; Power circuit 7 is power circuits that 110V converts 5V to.

As shown in Figure 2, the control setup of making according to the utility model is installed in the TAX2 case of locomotive, and monitor recording device installs to this by establishing information such as communication interface transmission kilometer post, speed, distance in the TAX2 case.

LKJ2000 type monitor recording device, TAX2 case are existing fexible unit model on the locomotive.
