For safe loop of vehicle door, its function, except controlling the opening and closing of car door, also needs to realize carrying out fault in time when car door breaks down and declares.But traditional Car's door controlling device does not feed back the information of any identification when declaring fault, so it is indiscriminate that fault declares each Car's door controlling device of connecting in a safety return circuit in process, the system that responsible handling failure is declared directly cannot lock the position that fault occurs.In existing secondary safety loop, subordinate's safety return circuit is in units of compartment, so just can learn when fault is declared fault comes from which concrete subordinate loop, also just fault coverage can be determined, in the compartment that this subordinate loop covers, to reduce the scope of trouble shoot to a certain extent.And for safe loop of vehicle door of the present invention, declare if utilize traditional vehicle door controller to carry out fault, then fault may come from any one car door of train, and maintainer has to all car doors to check one time successively.If car door quantity is more in train, so lock abort situation and just must consume a large amount of manpowers and time, the maintenance for fault brings serious difficulty.So under the application scenarios that car door quantity is many, the value not possessing practical application embodiment illustrated in fig. 1.
Safe loop of vehicle door described in the present embodiment is by overcoming above-mentioned defect for the optimization of described Car's door controlling device, and concrete with reference to Fig. 2, described in the present embodiment, safe loop of vehicle door comprises:
Car door administration module, for sending corresponding coach number information and car door information for each Car's door controlling device, and receives the fault that Car's door controlling device sends and declares information;
Described car door administration module realizes based on Train Control and management system (Train Control and Management System is called for short TCMS); In the city rail vehicle of present stage, the function treatment car door of TCMS also comprises monitoring air-conditioning, traction, braking, the control of high-speed circuit breaker condition monitoring etc. outside managing, but in the present invention, is only applied to the partial function that TCMS only relates to car door management.Described car door administration module plays the effect of control and management effect to Car's door controlling device; Car door administration module comprises the corresponding coach number information of car door that this Car's door controlling device controls and car door information to the information that Car's door controlling device sends.Namely coach number information and car door information designate compartment and the numbering of this car door in this compartment at car door place corresponding to this Car's door controlling device, namely directly determine the position of some car doors.
Car's door controlling device, for controlling the opening and closing of car door; And when car door exists fault, coach number information and car door information Write fault are declared information, the fault information of declaring is sent to car door administration module.
The coach number information received before and car door information, when generation fault declares information, are written to fault and declare in the middle of information by the device of Car's door controlling described in the present embodiment; This step is also the final steps realizing abort situation directly to lock onto concrete a certain car door.Aforesaid car door administration module sends coach number information and car door information is that this step provides necessary prerequisite to this link of Car's door controlling device.Car door administration module receives the fault comprising coach number information and car door information and declares information, just directly can determine that fault has appearred in which car door in specifically which compartment.
Safe loop of vehicle door described in the present embodiment comprises a relay equally, its function is identical with embodiment illustrated in fig. 1, safe loop of vehicle door described in the present embodiment is taked consistent with embodiment illustrated in fig. 1 equally, directly by single step arrangement that relay is connected with Car's door controlling devices all in the middle of train.Repeated description is not made at this.
Safe loop of vehicle door described in the present embodiment can also comprise display, for receive at car door administration module fault declare information time, display fault declares coach number information in information and car door information.
In the present embodiment, by car door administration module for Car's door controlling device sends coach number information and the car door information of the car door that this Car's door controlling device controls; When described Car's door controlling device feedback fault declares information, corresponding coach number information and car door information Write fault are declared in information.So described car door administration module is when receiving fault and declaring information, the position of fault car door just directly can be determined.Thus, by the optimization to described Car's door controlling device in the present embodiment, Car's door controlling device is made to feed back car door position when fault is declared, avoid described safe loop of vehicle door when car door quantity is many, locking abort situation just must consume a large amount of manpowers and the defect of time, make the technical scheme of described safe loop of vehicle door more complete, under various application scenarios can being applied in widely.
In the present embodiment, do not make concrete restriction to described Car's door controlling device, every Car's door controlling device that can possess similar functions all can be applied under the overall technical architecture of the present embodiment.But, in order to make technical solution of the present invention openly more abundant, list a kind of Car's door controlling device that can realize function described in the present embodiment once.In the present embodiment, available Car's door controlling device includes but are not limited to door controller once get off.
With reference to Figure 3 shows that a kind of selectable Car's door controlling device in safe loop of vehicle door of the present invention.The structure of described Car's door controlling device as shown in Figure 3, specifically comprises:
Control circuit unit, for controlling the opening and closing of car door;
Described control circuit unit realizes Car's door controlling device traditional function, namely controls the functional unit of door contact interrupter; And the signal of telecommunication in the signal of telecommunication of described breakdown judge foundation i.e. control circuit unit.
The current signal of telecommunication of control circuit unit comprises first signal of telecommunication and second signal of telecommunication; And the unit of control circuit described in the present embodiment comprises:
First switch contact, for generating first signal of telecommunication, and is sent to detecting unit by network by first signal of telecommunication;
Second switch contact, for generating second signal of telecommunication, and is sent to detecting unit by circuit by second signal of telecommunication;
Above-mentioned two contact switch are all closed when door closing, disconnect in car door opening formula; And the signal of telecommunication changes when opening and disconnect.Difference is that described first switch contact sends the signal of telecommunication by network, and second switch contact sends the signal of telecommunication by circuit; Two pairs of contact concurrent workings, and only have when the two pairs of contacts all show car door normally close when, train can be exercised, so the setting of two pairs of contacts is a kind of means increasing vehicle safety in the present embodiment.
In addition, described second switch contact is linked in the middle of pulliung circuit, and when second switch contact is not closed, pulliung circuit disconnects, and also just achieves so-called tractive force and block, namely stop train driving when car door is not closed.
Detecting unit, for the conventional telecommunications number according to described supply side information determination control circuit unit, and judges that the current signal of telecommunication of control circuit unit is whether number consistent with conventional telecommunications, if inconsistent, thinks that the signal of telecommunication is incorrect; Whether detecting unit is also consistent with second signal of telecommunication for detecting first signal of telecommunication, if inconsistent, thinks that the signal of telecommunication is incorrect.
In train driving process, be called by the drivers' cab one end used and occupy end; Because general city rail vehicle is all two way, two ends are equipped with a drivers' cab, and driver drives in the drivers' cab of front (along direct of travel) in the process of moving; The drivers' cab in described front is just called as and occupies end.City rail vehicle described in the present embodiment is selected in non-one end occupied for described door control system provides power supply, and city rail vehicle two ends general are in other words symmetrical, can occupy or power; The setting adopting one end to occupy the other end in actual traveling to power.Described supply side information is exactly indicate the information of occupying end and feeder ear position.And owing to occupying under the pattern that the other end powers in one end, the signal of telecommunication is flowed to by feeder ear and occupies end, so Car's door controlling device can determine theoretic signal of telecommunication situation in self circuit according to the position of feeder ear.If but break down when this car door, cause car door cannot normal switch time, will cause the signal of telecommunication situation in Car's door controlling device and the theoretic signal of telecommunication inconsistent.Car's door controlling device is once detect that namely this inconsistent situation thinks that this car door breaks down.Detecting unit can determine the theoretic signal of telecommunication in control circuit unit according to the position of feeder ear, using this theoretic signal of telecommunication as conventional telecommunications number.
Reference Fig. 4, Fig. 4 are the structural representation that described Car's door controlling device is connected into safe loop of vehicle door in compartment.When vehicle A end occupies, during the power supply of B end, the signal of telecommunication flows to A from B, and midway is through each Car's door controlling device.Input and the output of described control circuit unit also adopt symmetric design, and when the signal of telecommunication flows to A from B time, all control circuit unit port one inputs, port 2 exports.If contrary to train inverted running, be then the power supply of A end, B holds and occupies, and so the input of control circuit unit and output also can be put upside down thereupon, and change port one output into, port 2 inputs.Occupy with only vehicle A end in the present embodiment, the situation of B end power supply is described.
In actual motion, the on off state of car door is divided into closed condition and opening.When vehicle A end occupies, B holds power supply; Control circuit unit port one inputs, and port 2 exports; The first described switch contact and second switch contact are the equal of just two switches on control circuit unit, and when closing of the door, the two pairs of contacts connect, and the signal of telecommunication can conducting, is two pairs of contact separation at car door opening, and the signal of telecommunication cannot conducting; Then in theory just can be understood as, during car door opening, control circuit at car door everywhere in off-state, electric current not conducting, input current potential is higher than output current potential; Work as closing of the door, control circuit is at car door everywhere in closure state, and current lead-through, input current potential equals output current potential.
So in above-mentioned situation, conventional telecommunications number is specially:
A end occupies, when the power supply of B end; Working as car door opening, port one current potential is higher than port 2 current potential; Work as closing of the door, port one current potential equals port 2 current potential.
Detecting unit is according to the above port one of criterion detection control circuit unit and the current potential of port 2; If the situation of the signal of telecommunication recorded and conventional telecommunications number is consistent, then the car door normal operation that this Car's door controlling device controls is described; If situation is inconsistent, illustrate that the unlatching of this car door or closed condition exist abnormal, namely detecting unit thinks that the signal of telecommunication is incorrect.
In addition, described detecting unit can also judge that whether first signal of telecommunication is consistent with second signal of telecommunication, in theory, the content of two signal of telecommunication feedbacks is necessarily consistent, but when inconsistent if there is the two, also just illustrate that certain fault or network failure have appearred in this car door place, detecting unit thinks that the signal of telecommunication is incorrect at this moment equally, starts follow-up fault and declares.
Fault message unit, declares information for generating fault when the signal of telecommunication is incorrect, described coach number information and car door information Write fault is declared information;
The unit of fault message described in the present embodiment is realize the functional unit that fault detect is accurate to concrete car door.In the present embodiment, each car door has a corresponding Car's door controlling device, and the particular location of this car door that coach number information and car door information are indicated.Coach number information and the car door information Write fault of the car door that this Car's door controlling device controls by described fault message unit declare information, then car door position of clearly breaking down that can be concrete by this fault information of declaring.
Communication unit, declares information for collecting fault, and the fault information of declaring is sent to car door administration module;
In real time, described Car's door controlling device is main gating device and from gating device two kinds of general names for the device of close door.Described main gating device and the difference from gating device are just whether can complete communicating in described car door administration module; Namely be whether be provided with communication unit.In general for a joint compartment, as long as be provided with a main gating device, the fault that can realize collecting in whole compartment in all Car's door controlling devices is declared information, and is sent to car door administration module.So under practical application scene, there is no need as each Car's door controlling device arranges communication unit, in the present embodiment, two main gating devices are set in a joint compartment, be wherein responsible in normal conditions communicating with car door administration module for one, another is redundance unit, as subsequent use.
Isolating switch, for closed fault car door, and prompt system ignores this car door fault.
Determine that a certain car door is deposited in the case of a fault, due to the restriction of some condition in actual motion, not necessarily can complete maintenance for fault car door in the very first time.If but do not do any type of process, then according to the security mechanism of general vehicle, when certain car door place exists fault, vehicle can not continue to run.And the effect of isolating switch is, after determining that a certain car door breaks down, just utilize isolating switch to be isolated by fault car door, make system ignore this fault and do not affect train continuation operation.
