Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.

[0015] Example. A test method for an elevator control cabinet, which is to connect the elevator control cabinet to be tested with an unloaded traction machine and control the operation of the traction machine, and control the operation of the elevator in the well on site according to the operation and direction of the traction machine. The state is simulated, and then the simulated information in the hoistway is transmitted to the control cabinet to be tested, so as to realize the comprehensive operation simulation of the function of the elevator control cabinet to test the correctness and reliability of the elevator control cabinet. The method for simulating the running state of the elevator in the well on the spot according to the operation and direction of the traction machine is: setting a plura...

Abstract

The invention discloses a method and a device for testing elevator control cabinets. The method for testing elevator control cabinets includes: connecting a to-be-tested elevator control cabinet with an unloaded tractor, controlling running of the tractor, simulating running states of an elevator in a field shaft according to running and direction of the tractor, transmitting simulated information inside the shaft to the tested control cabinet, and finally realizing comprehensive running simulation of functions of the elevator control cabinet so as to detect correctness and reliability of the tested elevator control cabinet. The method and the device for testing the elevator control cabinet can be widely applicable to various elevator control cabinets, testing process is more suitable for actual working conditions and testing results are more accurate.

Description

technical field [0001] The invention relates to a test method and device for an elevator control cabinet, belonging to the technical field of elevator control. Background technique [0002] The reliability and accuracy of the traction elevator control cabinet need to be tested before leaving the factory. As for the test of the elevator control cabinet, the most effective method is to connect the elevator control cabinet to the actual elevator system, and examine its reliability and accuracy by observing its operation, but this method is extremely unrealistic. At present, most elevator control cabinet tests use PLC to input various signals to the elevator control cabinet, then detect the output signal of the elevator control cabinet, and compare the detected output signal with the theoretical output signal to judge the elevator control cabinet. reliability and accuracy. However, this method cannot reflect the actual working conditions, so the accuracy of the test results is...
