Abstract
The utility model discloses an automatic display, heralding and redisplay device for railway protective signal, comprising a red plate, a heralding signal, a transmitting circuit and a redisplay device. The utility model is used for the work field of railway transportation. The utility model displays the track, and the red plate is raised. The utility model displays the faults of the time, a transmitter and the heralding signal and queries and displays the work conditions of the track in seven days.
Description
The utility model relates to a kind of railway protection signal and shows, gives announcement, multiple showing device automatically.This device is suitable for section indication of railway transporting operation station or registration of vehicle position.
At present railway interests is when carrying out loading and unloading operation, and for the personal safety that ensures the operating personnel and the safety of vehicle arrangement, the front end in nearly operating area, loading and unloading operation station track adopts red card, and red light is as protection signal.Though this kind protection signal can avoid other vehicles to enter this station track once more, but range of a signal is short, and whether production scheduling personnel certain station track of having wanted to be situated between have car, must come to operation field personally and observe, otherwise can't Jie's circuit actual conditions, thereby influenced dispatcher's work efficiency greatly.
The purpose of this utility model is will provide a kind of can correctly show the operation situation at a distance, ensure the safety of operating personnel and vehicle arrangement, can make the dispatcher not go out the protection signal that the operation department just can fully understand each bar circuit condition of service again and show, give announcement automatically, answer showing device.Use the utility model also can be on demand at any time the condition of service of each station track that is situated between, even inquire about the nearly seven days operation situation in each station track, this all has positive effect to the level of scientific management that improves despatching work efficient, improves railway transportation.
The purpose of this utility model is finished as follows: shown, given by red card, red light and accuse the railway protection signal that signal, repeating signal three parts form and show, give announcement automatically, answer showing device.Wherein famous red light shows and is made up of red card, red light, limit switch, relay.When loading and unloading operation is carried out in certain station track, hold up by the red card that manually will be installed on this operating area, station track front end sleeper, make limit switch open contact closure, the actuating of relay, red light on one group contact point is sent out a warning, another group contact are delivered to power supply by cable and are given the AC contactor of accusing signal.
Giving the announcement signal is made up of beacon, can, AC contactor, red eye, greensignal light, micro controller system, transmission circuit.The left and right sides, beacon top is equipped with two groups respectively and is represented adjacent two station tracks busy not busy red eye, greensignal light.AC contactor, micro controller system, radio transmitter circuit all are contained in the can of position, beacon middle and lower part, after certain station track red card is holded up, the AC contactor action of accusing signal is given in this station track, its normally closed contact disconnects, primitive green signal lamp on the beacon top is gone out, and its two pairs of open contact closures make red eye bright simultaneously, two make micro controller system export the pairing code signal of this number red card, launch by transmission circuit.
Accuse signal lamp just often when giving, be serially connected in and give the dried spring G that accuses in the signal lamp loop
1, G
2The closing of contact makes marking signal of transmission circuit per minute emission with computer software, and the acceptor circuit per minute is received marking signal, if a certain giving accused the signal lamp damage, because dry-reed tube G
1, G
2Coil do not have electric current to pass through, contact open, acceptor circuit just can not receive marking signal, the cooresponding not under command light of repeater display panel is bright, and sends sound alarm.
Repeater is made up of acceptor circuit, reception display logic, repeater display panel.Acceptor circuit detects, differentiates according to the code signal of receiving, correct signal is passed to receiving and displaying system, make by logic and computer software and to show that again display panel makes corresponding demonstration, comprise a strand Taoist monastic name, red card number, time, week, standard time clock, again show demonstration such as red light, fault and inquiry, station track, week correction, the time, button such as minute, second correction.After certain station track red card is holded up, answering of corresponding station track shows that red light is bright on the repeater display panel, and show lighting time, when this station track operation finishes, when falling down red card, the repeater red light of this station track goes out on the repeater display panel, the time that the time showing window cooperates Alternation Display light-emitting diode Alternation Display red card to hold up and fall down.
Use the utility model not only to make the safety of operating personnel's personal safety and vehicle arrangement more reliable, more secure and dispatcher is at the indoor condition of service that can understand each station track by the repeater display panel, to guarantee railway safety, worker's personal safety, increase work efficiency, put forward the high site level of scientific management positive role is all arranged.
