Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
With reference to figure 1 and Fig. 2, a kind of switch board testing table, comprise testing table main body 100, servo-driver 200, servomotor 300 and scrambler, testing table main body 100 comprises host computer and the controller being connected with host computer, scrambler is connected with servomotor 300 respectively with servo-driver 200, and host computer is connected with servo-driver 200 by controller.
As the preferred scheme of one, the scrambler in the present embodiment has adopted absolute type encoder 400.Its advantage is: because its each position is definitely unique, anti-interference, without power-failure memory, angle, linear measure longimetry and positioning control in various industrial systems have been applied to more and more widely, therefore can guarantee the precision of position feedback in the present embodiment, improve the accuracy of test result.In the situation that those skilled in the art can be known, can adopt the scrambler of other types to reach and be equal to absolute type encoder 400 or approaching effect, as incremental encoder.
As the preferred scheme of one, the controller in the present embodiment has adopted Programmable Logic Controller.Its advantage is: Programmable Logic Controller is the electronic system of a kind of digital operation operation, application and designing under industrial environment specially.It adopts the storer that can program, be used for carry out stored logic computing and sequential control, regularly, the instruction of the operation such as counting and arithmetical operation, and by input structure mouth and the output interface of numeral or simulation, control various types of plant equipment or production run.In the situation that those skilled in the art can be known, can adopt the controller of other types to reach and be equal to Programmable Logic Controller or approaching effect.
Host computer adopts computing machine, by communication bus and Programmable Logic Controller communication.The output point of Programmable Logic Controller is connected with the input point of tested switch board 500, and the input point of Programmable Logic Controller is connected with the output point of tested switch board 500.Concrete connected mode: as being connected with switch board via serial communication plate and/or being directly connected with switch board.
While testing the position feedback function of switch board: host computer is by Controlled by Programmable Controller servo-driver 200, drive servomotor 300 to turn round, produce elevator car position deviation signal, then absolute type encoder 400 is carried tested switch board 500 by the car position deviation signal of generation, tested switch board 500 is finely tuned the traction machine 600 of elevator according to car position deviation signal, simultaneously Programmable Logic Controller is connected to host code device on the traction machine 600 of elevator and gathers the operation conditions of traction machine 600, feeds back to host computer.The equipment volume of the limiter of speed in elevator device is huger, although directly adopt this limiter of speed and scrambler to reach, produce test desired position shifted signal, the very trouble but test is got up, adopt servo-driver 200, actuator and absolute type encoder 400 to replace limiter of speed and the scrambler in elevator device herein, when reaching test effect, simplified testing apparatus, also reduced and tested required implementation cost.
While testing the conventional func of switch board: host computer issues operational order to Programmable Logic Controller, the instruction that Programmable Logic Controller issues according to host computer is exported corresponding signal to elevator control cabinet, a series of actions state of Programmable Logic Controller fast detecting elevator operation simultaneously, then be uploaded to host computer, host computer records the feedback information of Programmable Logic Controller, comprise the input/output signal of tested switch board 500, by the logical relation of input/output signal relatively being judged to the major loop of tested switch board 500, electric power loop, signal circuit, control loop, safety return circuit, the correctness of ac circuit and alarm circuit, and testing result is shown.
