Abstract
The invention discloses a door position detecting device with a CAN bus fault diagnosis function. The door position detecting device comprises a coil, an induction switch, a controller and a CAN bus transceiver, wherein the mounting position of the coil matches the induction switch. The induction switch is connected with the controller. The controller is connected with the CAN bus transceiver. The CAN bus receiver easily determines the state of the door according to detecting information which is supplied from the controller, namely a closed state or an open state. When the door is in the open state, the door position detecting device disables an engine and other devices which may cause dangers from starting. When the controller is in an offline state or a breakdown state, the door position detecting device disables the engine and other devices which may cause dangers from starting, thereby ensuring high safety in operation of a bus.

The detection means for sending hatch door location status is just very necessary.But there is presently no so hatch door with self-diagnosing function
Position detecting device.
The content of the invention
It is an object of the invention to provide a kind of hatch door position detecting device with CAN fault diagnosis functions, leads to
The application of the device is crossed, existing problem is solved.
To solve above-mentioned technical problem, the present invention is achieved by the following technical solutions：
It is of the invention to open for a kind of hatch door position detecting device with CAN fault diagnosis functions, including coil, sensing
Close, controller and CAN transceiver, the installation site of its coil is engaged with inductive switch, the inductive switch with control
Device processed is connected；The controller is connected with CAN transceiver.
Further, when controller is first powered on, the controller is produced to the coil power supply on hatch door, the coil
Magnetisation field, closes inductive switch, and now controller detects the closure signal of inductive switch；The inductive switch make delay three
To after five seconds, the controller stops to coil power supply, disconnects inductive switch, and now controller detects the disconnection of inductive switch
Signal.
Further, the controller draws testing result then according to the detection signal for receiving, and testing result is sent out
CAN receiver is sent to, wherein detection signal includes inductive switch closure signal and inductive switch cut-off signal, the detection
As a result failure or hatch door position detecting device is not had to there is failure including hatch door position detecting device.
The invention has the advantages that：
The detection information that CAN receiver of the present invention is provided according to controller, is easy to judge hatch door status, that is, locate
In closed mode or opening, when under hatch door opening, then the device controls engine and other may cause danger
Device fail to start；When controller is under broken string with deadlock state, then the device controls engine and other may cause
Dangerous device fail to start, so as to ensure the security that car is operated.
Certainly, the arbitrary product for implementing the present invention it is not absolutely required to while reaching all the above advantage.
Description of the drawings
In order to be illustrated more clearly that the technical scheme of the embodiment of the present invention, use required for describing to embodiment below
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for ability
For the those of ordinary skill of domain, on the premise of not paying creative work, can be attached to obtain others according to these accompanying drawings
Figure.
Fig. 1 is a kind of circuit system of hatch door position detecting device with CAN fault diagnosis functions of the present invention
Schematic diagram.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer to shown in Fig. 1, the present invention is a kind of hatch door position detecting device with CAN fault diagnosis functions,
Including a controller 3 of inductive switch 2, of coil 1, and a CAN transceiver 4, its coil 1 is arranged on cabin
Men Shang, inductive switch 2 and controller 3 are installed on the vehicle frame near hatch door, and installation site and the inductive switch 2 of coil 1 match
Close, inductive switch 2 is connected with controller 3；Controller 3 is connected with CAN transceiver 4.
When controller 3 is first powered on, controller 3 is powered to the coil 1 on hatch door, and coil 1 produces magnetic field, makes sensing
Switch 2 is closed, and now controller 3 detects the closure signal of inductive switch 2；After the time delay 3-5 seconds, controller 3 stops on hatch door
Coil 1 power, disconnect inductive switch 2, controller 3 detect inductive switch 2 cut-off signal；When controller 3 receives sensing
After closure and the cut-off signal of switch 2, determine that hatch door position detecting device be do not have it is faulty, conversely, the then hatch door position
There is failure in detection means.The information for detecting is sent to CAN receiver 4 by controller 3 by CAN signal line, wherein
The information for detecting does not have failure and hatch door position detecting device to there is failure, CAN signal line including hatch door position detecting device
Including CAN height and the low both threads of CAN.
Hatch door position detecting device after the completion of self detection, to the coil 1 on hatch door power by controller 3；Hatch door is opened,
Away from inductive switch 2, inductive switch 2 disconnects the coil 1 arranged on hatch door, and then controller 3 receives cut-off signal, by CAN
Bus is sent to CAN receiver 4；Hatch door is closed, and the close inductive switch 2 of coil 1 arranged on hatch door, inductive switch 2 is closed
Close, then controller 3 receives closure signal, is sent to CAN receiver 4 by CAN.
Controller to CAN receiver 4 sends digital information that is continuous and being continually changing, if CAN receiver 4 is examined
After measuring digital information that is continuous and being continually changing, then controller 3 is judged in normal detection state, conversely, then judging
Controller 3 crashes or breaks.
The detection information that CAN receiver 4 is provided according to controller 3, fail to start engine under hatch door opening
And other may cause danger device, controller 3 in broken string or deadlock state under fail to start engine and other can
The device of danger can be caused, the security that car is operated has been ensured.
One of the present invention has particular application as：When hatch door is in opening, the coil 1 on hatch door is mounted in far away from sensing
Switch 2, inductive switch 2 disconnects, and controller 3 is received after cut-off signal, is opened hatch door with the low both threads of CAN by CAN height
Status signal is sent to CAN receiver 4；When hatch door in off position when, be mounted in the coil 1 on hatch door with regard to proximity switch 2,
Switch 2 is closed, and controller 3 is received after cut-off signal, sends out hatch door closed mode signal with the low both threads of CAN by the way that CAN is high
Give CAN receiver 4；So as to obtain the location status of hatch door.
