The interaction of network control system.
Fig. 2 to Fig. 8 is refer to, embodiments of the invention are：A kind of track train controller is applied on subway train, is made
Being substituted with contactless electron circuit softPLC scheme has the relay logic circuit control program of mechanical contact, another to have heat
The functions such as standby redundancy.
The present embodiment, according to the space requirement of equipment cabinet, is pacified in subway train equipment cabinet using rack fastened by screw
Dress, using aluminum alloy material, weight is no more than 10kg, and operating ambient temperature is -25 DEG C~70 DEG C, degree of protection IP20, is used
The radiating mode of surface anodization technique and natural cooling.
The track train controller of the present embodiment uses the tactic pattern of standard 3U cabinets, and its feature card plate falls into 5 types,
Respectively：Tablet, output board, control panel, power panel and network service plate (apolegamy).
Input signal interface board and output signal interface board be connected respectively cabinet input signal and output signal line, three pairs
It is defeated that electric switch signal, a pair of control plate that tablet is used to detect on vehicle are responsible for the service logic of complete machine, two pairs of output boards
It is responsible for the output of logic control signal, two sets of identical and mutually independent insulating power supplies built in one piece of power panel.All business boards can
Plug, in cabinet back designs PCB backboards, backboard is provided with slot and is used to patching each business board, between business board, business board with
Connected between connection jaws by PCB trace.Business data information between boards are entered by " U-shaped " CAN on backboard as medium
Row interaction.
Electric switch signal on train is transferred to cabinet by wire, and the wire at connection cabinet end need to pass through the side of crimping
Formula is plugged on the connector matched with cabinet, then is connected with cabinet, in the input being electrically adapted to and output type signal electricity
Put down as 110V and 24V.4 indicator lamps are equipped with every piece of business board panel, for active/standby, failure, work, communication instruction.Its
In every two blocks adjacent identical services plates assemble and put as the one of mutual standby redundancy, it is automatic when one of business board breaks down
Another piece of business board work is switched to, obtains control, active/standby indicator lamp is used to indicate the business board for being currently owned by control,
Another business board is in standby ready or failure closed mode.Indicator lamp on tablet panel is used for the shape for indicating input signal
State, lamp is bright to indicate input, and lamp, which goes out, indicates no input.Two DB9 interfaces are designed with control panel panel, and (the pin data of D types 9 connect
Mouth connector, for connecting electronic equipment), the network communication interface being respectively used between complete machine maintenance interface and compartment.Defeated
The logic light of state output and reality output status indicator lamp are designed with ejecting plate panel, for intuitive judgment output whether
Effectively.Two DB9 interfaces are designed with power panel panel, an interface is used to configure cabinet in vehicle (network) system
Coding, another interface are used for the multiple cascade for carrying out cabinet, can carry out the flexible configuration and Function Extension of resource, and indicator lamp is used
In instruction power supply power supply state.
Fig. 2 show system block diagram, and all business boards and power panel are all patched on backboard, it is illustrated that in adjacent complete phase
With plate A and plate B respectively as hot backup redundancy a pair of business boards, business board include tablet, output board, control panel, signal
Input interface plate and signal output interface plate.The input signal interface and the back of the body that external input signal line passes through signal input interface plate
PCB trace on plate is assigned to each tablet, and the output signal of output board is connected to the defeated of signal output interface plate by backboard
Go out on signaling interface, be connected with the output control line of outside.Complete machine power supply introduces backboard from output signal interface board, respectively
Business board is from power taking on backboard power source bus.All business boards are plugged on backboard in a manner of plug-in unit, are passed through on backboard
The relation that PCB layout designs between relation and business board and outer signals between each business board is the basic load of system schema
Body.All input signal cables are divided into 3 groups on backboard, are connected respectively on the pin position of 3 groups of tablet slots, each group of input
The signal that plate A and B is detected is identical, and A plates and B plates are mutually for redundancy, and similar therewith, output board is divided into two groups, and output signal line passes through
Backboard is connected to output interface, has one group of control panel, two sets of same power supplies built in power panel.
The slot position of each business board is equipped with a unique coding information, referred to as slot number on backboard, works as industry
It is engaged in after the upper electricity of plate insertion, you can the coding is read, so as to obtain the location of itself.Also being designed with each slot position can
Encoded from the cabinet of exterior arrangement, the coding information of cabinet where can be read after business board insertion.
Every piece of business board is designed with processor and CAN communication interface, and all business boards pass through the CAN on backboard
Data interaction is carried out, control panel is as data processing and headend, the core business of responsible system.Every piece of business board is in backboard
Upper two CAN communication interfaces of opening, respectively CAN3 and CAN4, the CAN3 interfaces of all business boards are articulated on same bus,
The CAN4 interfaces of all business boards are articulated on same bus.CAN3 and CAN4 hot backup redundancies, any one group of communication bus occur
Systematic function is not influenceed during failure.CAN3 and CAN4 buses are in " U-shaped " winding in cabinet, DB9 interface of the one end from power panel
Into turning again to the DB9 interfaces of power panel as the other end after all Peripheral Interfaces in mounting on backboard.This design
Mode can conveniently carry out the extension of multistage cabinet or carry out the multi-tier of other functional products.
Fig. 3 show core bus schematic diagram, and dotted line represents the turn back line of CAN in the chassis, solid line entrance in figure
Upstream equipment is connected, terminal resistance is connected if without upstream equipment, dotted line entrance connection upstream device, is connected if without upstream device
Connect terminal resistance.
To make A plates in each group of business board and B plates preferably cooperate, reach optimal hot backup redundancy effect,
Mutually exclusive data interaction communication link is devised between A plates and B plate slots on backboard, the same of data can be carried out at any time
Step backup, the hot plug event of other side is detected by the level state of hard wires, it is ensured that reach when needing and being controlled power switching
To effective transition effect.
In addition, considering the compatibility of signal type in the signal definition of back panel connector, wrong plug business board is avoided to cause
Burn plate phenomenon.Because each type of business board has coding, its groove position that can be taken can be configured, when wrong plug business board
When, it can be also identified, be protected with reminding by configured encoding mechanism.
Signal input interface plate and signal output interface plate pass through PCB as backboard and the pinboard of external input signal
Wiring realizes that port is connected using insertion connector, anti-reverse.
