Abstract
The utility model provides a central control system of subway platform screen doors. In particular, the central control system is composed of programmable controllers, a Y-Link suite, power supply modules, and an I/O module. The central control system has the advantages including strong expansibility, strong functions, easy programming, high reliability, small size and convenient maintenance.
Description
Technical field
The present invention relates to the automatic control technology field, specifically, relate to a kind of central control system of subway shield door.
Background technology
The subway station is the bigger place of flow of the people, in order to guarantee passenger's safety, between platform and track, shield door is installed.After train entered the station and rests in appointed positions, shield door was opened and is let up and down train of passenger, and after all shield doors were closed and locked, screen door sent " door complete shut-down and locking " signal to train system, allows train to sail out of the station.At present; The control system of most of subway shield doors all is to adopt the mode of relay control; This control mode implement have bulky, the production cycle is long, wiring is complicated, failure rate is high, reliability and very flexible, extendability are poor, and has no idea to realize real hardware redundancy.
Summary of the invention
In view of this, the purpose of the utility model is to provide a kind of security and reliability is high, extendability is strong, volume is little, function is strong, programming is easy, easy to maintenance subway shield door control system, and particular content is following:
A kind of central control system of subway shield door, said central control system comprise PLC, Y-Link external member, power module, I/O module;
Said Y-Link external member uploads to many said PLC synchronously with fieldbus, also can realize that internal data is synchronous with the optical fiber connection between the said PLC.
Said central control system has the control system of the mutual real time monitoring of two covers, and every cover control system all has CPU, power supply, communication module and Y-Link external member; A following in working order wherein cover control system is a master controller, and another set of system is a slave controller, and said master controller is state of activation and the control function of undertaking said central control system; The role of said master controller and said slave controller can switch automatically.
The time of said switching is not more than 10 milliseconds.
Said central control system is reported to the police when said master controller breaks down, and said slave controller activates and switch to duty.
The central control system of the subway shield door of the utility model, its effect is following:
1. two cover PLC are independent operating, and again synchronously in real time, any cover PLC breaks down, and another set of PLC can in time switch, and becomes current operation PLC, bears the work of control section.And on surveillance and Long-Range Surveillance System, can report to the police, so that notify the maintenance personal to carry out maintenance process;
2. 64 inputs and 64 outputs are reserved in the utility model design, and can expand at any time;
3. be controlled by the signal system directive owing to shield door, and the various signals systems provider, different operation modes; The capital exerts an influence to the interface of signal system, causes interface shape varied, adopts the PLC control mode; As long as reserve good enough I/O, carry out a spot of modification of program, can realize different manufacturers; The butt joint of distinct interface form greatly reduces the cost of development and the maintenance cost of system;
4. PLC is connected with the platform door control unit through fieldbus, uploading unit door state and download parameter etc.Can carry out query modification to single door, also can carry out query modification in batches.
Description of drawings
Fig. 1 is the hardware configuration of shield door central control system;
Fig. 2 is the arrangenent diagram of shield door central control system.
Embodiment
Explanation through following examples helps to understand the utility model, but does not limit the content of the utility model.
Embodiment 1
The central control system of subway shield door comprises two controllers in the present embodiment; As shown in Figure 1, comprise the 412-3H type CPU (Siemens production) that 2 S7-400 are serial, 2 power supply (PS407; Siemens is produced); 2 communication modules (CP443-1, Siemens production), a cover Y-LINK coupling mechanism external member (Siemens production); Employing 2 covers fully independently programmable logic controller (PLC) (PLC) carry out hard Redundancy Design; The Y-LINK external member can upload to 2 PLC synchronously with a fieldbus (PROFIBUS), and the PLC internal data carries out really accomplishing the hard redundancy of subway shield door control system synchronously through 2 synchronous optical fiber.Through synchronizing cable two CPU are connected, can form Ethernet, carry out data interaction mutually, and be independent of each other with industrial computer MMS and PSA.
Two controllers are worked simultaneously, and mutually real time monitoring and information synchronization are in state of activation (that is what, be in state of activation is master controller but the same time only has a controller; Another is a slave controller), shoulder the control function of shield door central control system; When master controller breaks down; System alarm (reminding the repair and maintenance personnel in time to overhaul); Another controller can automatically switch to state of activation (being not more than 10 milliseconds switching time); That is, all information before being automatically switched to the status of master controller and continued fault fully by the status of slave controller are started working.
Above-mentioned master-slave network switching adds the supply of relay control repeater power supply through output module and realizes, in PLC software, switches master slave mode through activation and deactivation.
Claims (4)
1. the central control system of a subway shield door is characterized in that, said central control system comprises PLC, Y-Link external member, power module, I/O module;
Said Y-Link external member uploads to many said PLC synchronously with fieldbus, also can realize that internal data is synchronous with the optical fiber connection between the said PLC.
2. central control system according to claim 1 is characterized in that, said central control system has the control system of the mutual real time monitoring of two covers, and every cover control system all has CPU, power supply, communication module and Y-Link external member; A following in working order wherein cover control system is a master controller, and another set of system is a slave controller, and said master controller is state of activation and the control function of undertaking said central control system; The role of said master controller and said slave controller can switch automatically.
3. central control system according to claim 2 is characterized in that, the time of said switching is not more than 10 milliseconds.
4. central control system according to claim 2 is characterized in that, said central control system is reported to the police when said master controller breaks down, and said slave controller activates and switch to duty.
