Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example one

For solving traditional CAN bus and to carriage door ID setting, need the staff manual to carry out CAN communication to the carriage door switching on and shutting down one by one, the inefficiency just appears human error easily, and the current technique of carrying out carriage door ID setting through CAN communication simultaneously still needs to carry out the ID setting to the slave unit one by one through the master, and efficiency is the efficient problem still inadequately, combines fig. 1 and fig. 2, the utility model provides a door controller based on CAN bus intelligent configuration ID, including a plurality of door controller, host computer, CAN bus and hard wire in its main part, wherein:

the gate controllers are sequentially connected and used for sending an electric signal to the next gate controller through a hard wire after being electrified and broadcasting an ID number through a CAN bus;

the gate controllers are also used for generating an ID configuration instruction after receiving the electric signal sent by the previous gate controller, generating self ID numbers after monitoring the ID numbers broadcasted on the CAN bus and broadcasting the ID numbers through the CAN bus;

and the upper computer is used for receiving and storing the ID number on the CAN bus (because the upper computer cannot directly monitor the CAN bus, a debugging person carries the CAN-Ethernet equipment to connect the upper computer and the gate controller during actual application, thereby finishing the CAN bus monitoring function).

Specifically, in order to realize the functions of transceiving electric signals and ID numbers, the gate controller comprises a signal receiving unit, a signal generating unit and a CAN communication unit, wherein:

the signal receiving unit is used for receiving the electric signal sent by the previous gate controller, generating an ID configuration instruction and sending the ID configuration instruction to the signal generating unit;

the CAN communication unit is used for monitoring the ID number broadcasted on the CAN bus and transmitting the ID number to the signal generation unit;

the signal generation unit is used for generating an ID number of the signal generation unit according to the received ID number after receiving the ID configuration instruction, and sending a power signal to the next door controller;

and the CAN communication unit is also used for broadcasting the generated ID number per se through a CAN bus.

Through the mode of CAN bus communication, connect host computer and door controller in proper order, removed from traditional carriage door ID setting and need the staff to remove the trouble that sets up ID number before corresponding carriage door one by one with the configuration equipment, avoided the work error problem that the manual operation probably takes place simultaneously.

Simultaneously, because of the market demand of difference, the quantity of vehicle carriage door often can not be confirmed, consequently the utility model discloses a door controller can increase and decrease quantity according to actual demand. And in order to guarantee that the formation of door controller ID and feedback do not receive the influence of arranging the order between door controller quantity and the door controller, the utility model discloses set up the door controller of foremost into predetermineeing first door controller to parallelly connected with its power cord and signal receiving unit's input, thereby make its circular telegram back, directly generate first ID serial number by its signal generation module.

Meanwhile, in order to simplify the procedure of the ID number, the ID number generated by the gatekeeper after receiving the electric signal of the previous gatekeeper is added with 1 on the basis of the ID number sensed from the CAN bus to be used as the ID number of the gatekeeper. For example, if the number automatically generated by the first gate is assumed to be 100(N), the signal generation module of the subsequent gate generates the ID number of the number 101(N +1), the subsequent gate generates the ID number of the number 102(N +1+1), and so on.

Through the means, the CAN communication and the electric signal transmission between the gate controllers are utilized, the establishment of the ID numbers is completed on the gate controllers and is uploaded to the upper computer, the step that the upper computer generates the ID numbers independently and sends the ID numbers to the gate controllers is omitted, the step that the upper computer and the lower computer communicate back and forth when the traditional CAN buses are numbered is simplified, and the overall efficiency is improved. Meanwhile, the serial number adopts a form of N-N +1(N >0), and the ID serial number is carried out in the simplest mode, so that the self-coding generation can be completed only by simple coding, excessive memory cannot be occupied, and the efficiency is also improved.

In order to avoid the influence of a plurality of door controllers broadcast to CAN bus communication simultaneously, still carried out corresponding setting to the door controller: when the gater a has completed the ID number configuration, the generated ID number is 100, and broadcasts the ID number out through the CAN bus, and the next gater B generates the ID number 101 and broadcasts out through the CAN bus after receiving the electric signal and listening to the ID number of 100. At this time, the gater a listens to the ID number 101, determines that the number is larger than the self number 100, and stops broadcasting the self ID number. Through the processing, the influence of simultaneous broadcasting of a plurality of gate controllers on CAN communication CAN be avoided.

Further, the faults of some parts can be avoided in the use process of the door controller, the traditional door controller cannot well judge fault parts, and the faults need to be judged through the experience summary of maintenance personnel. Therefore, the door controller in still include overtime alarm unit for behind the door controller circular telegram, and surpass first preset time (concrete time can be adjusted according to the user demand):

successful power-on, but no ID configuration command (indicating signal receiving unit failure) is received by the signal generating unit, failure signal 1;

the ID number (indicating a failure of the signal generating means) and the failure signal 2 are broadcast but the power-on is successful.

Under the two conditions, the gate controllers CAN send out corresponding alarm signals through the CAN bus, the alarm signals comprise the ID number and the fault signals of the previous gate controller and are displayed in different forms (different color marks or different patterns) on the upper computer,

meanwhile, the upper computer is also provided with an overtime alarm unit which is used for sending out fault information 3 and displaying the fault information on the upper computer when the ID number or the alarm signal (indicating that the CAN communication unit of the door controller has a fault) is not received after the first preset time is exceeded.

Through setting up the overtime alarm on door controller and host computer, can be according to ID configuration instruction, ID serial number and alarm signal's receiving and dispatching state, the concrete position that damages of accurate judgement door controller makes things convenient for maintenance personal's judgement, time consumption when having reduced later stage maintenance.

the second port of the front door controller is connected with the first port of the rear door controller through a hard wire, wherein the first port of the first preset door controller positioned at the foremost end is connected with a switching power supply, and the second port of the door controller positioned at the rearmost end is suspended;

the third port of the gate controller is connected with an upper computer in parallel;

the fourth port of the gate controller is connected with one ends of parallel resistors R1 and R2 in parallel, and the other ends of the parallel resistors R1 and R2 are connected with an upper computer.
