Abstract
The utility model relates to double local controlling devices applied in subway shield door, which are characterized in that: two local control panels are respectively connected with the input terminal of a logic signal interface box by cables; the output terminal of the logic signal interface box is connected with the signal input terminal of a platform door controller; thereby the double local control panels realize to control the opening/closing of the subway shield door, and its work state can be monitored. Advantages: on the premise that the control panels on both the head and the tail of the train can be operated to control the shield door on the corresponding side, the device adds less components, can be mounted conveniently, and is especially suitable for existing engineering reconstruction; and a safety authentication circuit accorded with the signal system is applied for the inside shifting logic; is designed according to the principle of failure guiding safety, causes no reduction to system reliability, and achieves a stable work performance.
Description
Technical field
The utility model relates to a kind of two local control devices that are applied in the subway shield door, belong to the track traffic technical field.
Background technology
Domestic prior art constructions: shielding every body, composition such as control panel, shield door electrical system on the spot.Wherein, single control panel is on the spot realized the control to a side shield door, under this control mode, the driver can only carry out switch control to one-sided shielding every body at headstock or vehicle tail end, and is needing train under the situation that platform is turned back on the spot, and the driver needs to go to the tailstock from headstock, otherwise or, normal operation has caused bigger influence to train, causes the delay at the time of departure, and brings other potential safety hazard.
Summary of the invention
The utility model proposes a kind of two local control devices that are applied in the subway shield door.Its purpose is intended to overcome the above-mentioned defective of existing in prior technology, realizes the control mode of the one-sided shield door of control.
The utility model technical solution: it is characterized in that comprising logical signal interface box, shield door controller, two headstocks control panel on the spot, corresponding joining of signal I/O end of the first signal output/input of logical signal interface box and shield door controller wherein, secondary signal output/the input of logical signal interface box and first headstock be corresponding the joining of I/O end of control panel on the spot, and the 3rd signal output/input of logical signal interface box and second headstock be corresponding the joining of I/O end of control panel on the spot.
Advantage of the present utility model: the platform other end of control panel on the spot is being installed, increase a control panel on the spot, two on the spot the signal of control panel by the logical signal interface box handle, realize the priority interlocking, each on the spot control panel all can control this side shield door, simultaneously two on the spot the operation of control panel by the monitoring of the man-machine interface HMI in the shield door electrical system.All can operate on the spot control panel and control under the prerequisite of this side shield door satisfying the train head and the tailstock, the parts that increase are few, be convenient to install, be particularly suitable for transformation to existing engineering, and its inner switch logic adopts the circuit of the safety certification that meets signal system, according to the principle design of fault-safety principle, do not reduce the reliability of system, stable work in work.
Description of drawings
Accompanying drawing 1 is the structural representation that is applied in the two local control devices in the subway shield door.
Accompanying drawing 2 is structural representations of shield door controller.
The specific embodiment
Contrast accompanying drawing 1, comprise logical signal interface box, shield door controller, two headstocks control panel on the spot, corresponding joining of signal I/O end of the first signal output/input of logical signal interface box and shield door controller wherein, secondary signal output/the input of logical signal interface box and first headstock be corresponding the joining of I/O end of control panel on the spot, and the 3rd signal output/input of logical signal interface box and second headstock be corresponding the joining of I/O end of control panel on the spot.
Two on the spot control panel be connected on the input port of logical signal interface box by cable separately, after handling, the logical signal interface box outputs to the shield door controller, shield door controller control shielding door switch, realize two control panels on the spot to the control of the switch door of subway shield door, and to the monitoring of the duty of control panel on the spot.
Described logical signal interface box, its structure is made up of relay and holding circuit, wherein protection
The coil and the contact of circuit and relay join, and this holding circuit realizes the protection to fortuitous events such as overvoltage, overcurrents.
Contrast accompanying drawing 2, the structure of shield door controller mainly is made up of core cpu plate, relay module (a plurality of relays are formed), data storage circuitry, digital quantity input/output port, two CAN communication interface, Dual-Ethernet communication interface, power circuit etc.
The shield door controller is responsible for controlling and carrying out the switch door order of shield door and the running state information of gathering shield door by relay contact.The input termination external signal of relay group, be used for driving external circuit or gather external status signals, output is connected to CPU, and CPU is connected with memory circuit with Ethernet interface, CAN interface simultaneously, and power circuit is responsible for externally fed is converted to the voltage that is fit to the internal circuit use.
The course of work: the station staff operates the control panel on the spot of subway platform one end, send the order of switch door, after the logical signal interface box receives and handles, useful signal is sent to the gate controller, carry out switch motion by gate controller control shield door; Simultaneously, the logical signal interface box will forbid that work order sends to the control panel on the spot of the other end, make this on the spot control panel be in closed condition.When the station staff closes the control panel on the spot of current operation, at this moment, the former control panel on the spot that is in closed condition of the other end will restart, and will be in running order., do not turn around to travel and turn back on the spot at platform because of operation needs as railcar, the driver can operate former control panel on the spot of closing, the switch motion of control shield door.In this process, all on the spot the working state signal of control panel will send in the shield door controller by the logical signal interface box, the shield door controller monitors and sends the indication of reporting to the police when fault to duty.
Claims (2)
1. be applied in the two local control devices in the subway shield door, it is characterized in that comprising logical signal interface box, shield door controller, two headstocks control panel on the spot, corresponding joining of signal I/O end of the first signal output/input of logical signal interface box and shield door controller wherein, secondary signal output/the input of logical signal interface box and first headstock be corresponding the joining of I/O end of control panel on the spot, and the 3rd signal output/input of logical signal interface box and second headstock be corresponding the joining of I/O end of control panel on the spot.
2. the two local control devices that are applied in the subway shield door according to claim 1 is characterized in that described logical signal interface box, and its structure is made up of relay and holding circuit, and wherein the coil of holding circuit and relay and contact join.
