Abstract
The utility model belongs to the technical field of railway signal engineering and particularly relates to an outdoor misconnection-preventing alarm device for a signal switch machine. An outdoor signal switch machine is controlled by an indoor interlock system which carries out the consistency examination of outdoor equipment and indoor equipment. When wiring of an outdoor indication circuit is not correctly matched in maintenance, the indoor indication and the outdoor indication are not consistent, and a turnout can be switched to a direction opposite to the required direction, thereby causing a safety accident. The outdoor misconnection-preventing alarm device consist of an outdoor control unit and the indoor equipment; existing electrical signals of the switch machine received by a pulse trigger in the outdoor control unit is modulated and then is transmitted to the indoor equipment for comparing with existing signals of the interlock system received by a collector so as to complete the consistency examination. In the outdoor misconnection-preventing alarm device, a control panel is small, existing core wires can be used, an indoor comparison circuit and an indoor alarm are easy to install, and the anti-interference performance of an indoor control circuit and an outdoor control circuit is good, thereby effectively meeting the requirements of the error monitoring of the indoor and outdoor indication circuits.

Background technology
In the railway signal control system, switch machine is as the visual plant that guarantees train operating safety, and its radical function is to rotate track switch, guarantees that train moves on pre-set route.
National at present more than 6000 main ZD6-D of switch machine type existing and that adopt at the station of building, ZD6-E/J, ZD6-F/G, S700K, ZYJ7, ZDJ9 etc.The outdoor signal switch machine is to control through indoor interlock system; After the switch machine action is accomplished; Can accomplish the state of outdoor facility and indoor consistency check by interlock system through the indication circuit in the node drive chamber in the outdoor switch machine, reach the effect of monitoring.
This kind mode is to be to guarantee that indoor and outdoor control is consistent under the correct situation of outdoor switch machine wiring; But; If the switch machine maintainer can not can cause the expression of indoor and outdoor inconsistent, when handling the train receiving route distribution correct pairing of outdoor indication circuit when carrying out maintenance of equipment so; Can carry out reversing sense control to track switch to demand, can cause safety misadventure like this.
Summary of the invention
The purpose of the utility model provides a kind of can actv. preventing because the outdoor anti-error device taking alarm of signal switch machine of the outdoor switch machine misoperation that outdoor switch machine indication circuit connection mistake causes, prevents that track switch misrouting from changing the generation of the train operation accident that causes.
The technical scheme that the utility model adopted is:
The outdoor anti-error device taking alarm of a kind of signal switch machine is characterized in that:
This device is made up of interconnected outdoor control unit and indoor equipment;
Be provided with impulse trigger, suppressor and power supply changeover device in the described outdoor control unit, impulse trigger is connected with suppressor, and suppressor is connected with indoor equipment with power supply changeover device;
Be provided with the chain interface cabinet of constant-delay discriminator, collector, comparator and computing machine in the described indoor equipment, constant-delay discriminator and outdoor control unit, constant-delay discriminator is connected with comparator with collector, and the chain interface cabinet of computing machine is connected with collector.

Connect through the four-core signal cable between described outdoor control unit and the indoor equipment.
The utlity model has following advantage:
1, outdoor switch machine inner control plate bulk is little: because installing space is little in the existing outdoor switch machine, the inside cable distribution is more, and the utility model can adopt the less circuit card of volume to be installed in the switch machine, has high integrated advantage.
2, control cable existing heart yearn capable of using: the utility model utilizes the heart yearn in the cable of existing switch machine, and one the tunnel is the control heart yearn, and one the tunnel is power lead, reduces new cable laying causes owing to increase outdoor facility with high investment, high maintenance amount.
3, indoor comparator circuit, annunciator are easy to install: the utility model utilizes the clear position of the indoor modular block rack of signal machinery to install, and not needing increases control housing owing to increasing indoor equipment.
4, indoor and outdoor control circuit strong interference immunity: because the cable in the switch machine is high-tension cable, high-intensity magnetic field, heavy current interference are strong; The utility model adopts interference protection measure, satisfies the reliable and safety of information transfer.
5, can effectively satisfy the fault monitoring of indoor and outdoor indication circuit: the utility model adopts the comparator form; Utilize outdoor impulse singla of sending back to, have controller to carry out demodulation indoor, the information of fetching with interlocking compares; When satisfying unanimity; Display plate gives a green light, inconsistent sending out a warning, and can pass through alarm equipment alarm.
Description of drawings
Fig. 1 is the utility model johning knot composition.
Fig. 2 is the utility model outdoor control unit constructional drawing.
Among the figure, 1-outdoor control unit, the indoor lightning protection unit of 2-, 3-constant-delay discriminator, 4-collector; The 5-annunciator, 6-comparator, the chain interface cabinet of 7-computing machine, 8-indicator lamp, the existing switching machine electric signal of 9-; The 10-impulse trigger, 11-suppressor, 12-power supply changeover device, 13-indoor equipment.
The specific embodiment
Below in conjunction with the specific embodiment the utility model is carried out detailed explanation.
The outdoor anti-error device taking alarm of the described a kind of signal switch machine of the utility model is made up of with indoor equipment 13 interconnected outdoor control unit 1, connects through the four-core signal cable between outdoor control unit 1 and the indoor equipment 13.
Outdoor control unit 1 is made up of impulse trigger 10, suppressor 11 and power supply changeover device 12; Impulse trigger 10 is connected with suppressor 11; Suppressor 11 is connected with indoor equipment 13 with power supply changeover device 12; Indication circuit line in the outdoor switch machine is also received on the impulse trigger 10, makes existing switching machine electric signal 9 be input in the impulse trigger 10.
