Detailed description of the invention
A kind of overspeed protection device of rail cars, as shown in Figure 1, comprise speed measurement module 1, control module 2, display module 3, load module 4, alarm module 5, zero-speed functional module 6 and purpose overspeed protective module 7, described speed measurement module 1 is arranged on rail cars, the mouth of speed measurement module 1 is connected with the input end of display module 3, and is connected with the input end of load module 4; Described display module 3 is arranged on the driving position of rail cars; The mouth of described load module 4 is connected with the input end of control module 2; The mouth of described control module 2 is connected with alarm module 5, zero-speed functional module 6 and purpose overspeed protective module 7 respectively; Described alarm module 5 inside is provided with report to the police instruction flash light and instruction jingle bell of reporting to the police; Described purpose overspeed protective module 7 inside is provided with safety relay, and the mouth of purpose overspeed protective module 7 is connected with the brake system of rail cars.
The speed Negotiation speed measurement module 1 of described rail cars is measured.
The signal of described display module 3 inbound pacing measurement module 1, shows the real-time speed of rail cars.
The ratio value of the velocity constraint that described alarm module 5 gives the alarm carries out manual amendment by load module 4, and load module 4 is connected with control module 2 data transmission.
Described alarm module 5 receives the signal of control module 2, when the real-time speed value of rail cars exceedes by locomotive work personnel speed limit set in advance 85%, starts report to the police instruction flash light and instruction jingle bell of reporting to the police.
The limit value of described zero-speed functional module 6 carries out manual amendment by load module 4, and load module 4 is connected with control module 2 data transmission.
Described zero-speed functional module 6 receives the signal of control module 2, when the limit value of zero-speed function lower than setting of the running velocity of rail cars, triggers zero-speed function.
The speed limit that purpose overspeed protective module 7 carries out overspeed protection can be modified setting by load module 4, and load module 4 is connected with control module 2 data transmission.
Described purpose overspeed protective module 7 receives the signal of control module 2; when the real-time speed value of rail cars exceedes by locomotive work personnel speed limit set in advance 100%; the safety relay of purpose overspeed protective module 7 disconnects, and controls rail cars brake equipment emergency braking.
The speed measurement module 1 be arranged on rail cars obtains the electric signal corresponding with rail cars real-time speed accurately and rapidly, and by this electric signal, the display module 3 be sent on rail cars shows, observe to facilitate rail cars staff, meanwhile, this electric signal is sent to control module 2 by load module 4.
The overspeed protection device of a kind of rail cars of the present invention realizes zero-speed function by zero-speed functional module 6; the limit value of zero-speed function can manually be modified by the load module 4 be connected with control module 2; when the limit value of zero-speed function lower than setting of the running velocity of rail cars, control module 2 controls zero-speed functional module 6 and triggers zero-speed function.
