Elevator floor display detection device

Abstract

The invention relates to an elevator floor display detection device. The elevator floor display detection device comprises a controller and further comprises a signal simulator, an encoder frequency division card, a power device and an operator, wherein the signal simulator is used for receiving a pulse signal, converting the pulse signal into an analog signal and inputting the analog signal into the controller. The encoder frequency division card is used for reading the autorotation motion of an encoder and converting the autorotation motion to generate the pulse signal. The power device is driven by the controller to rotate, and the encoder is coaxially mounted on the power device. The operator is used for setting parameters of the controller. Through the arrangement of structures such as the power device, the signal simulator and a display test interface, the signal simulator can simulate the state information of switches such as an upper flat layer, a lower flat layer, upper and lower forced speed reduction, upper and lower limiting positions and the like in an elevator shaft; and by additionally arranging an external interface directly connected to a display, the display content of the developed novel elevator floor display can be effectively checked and debugged, personnel do not need to collect data of a real elevator on site, a plurality of electrical signals are detected, the test is accurate, and the efficiency is high.

Description

technical field [0001] The invention relates to the technical field of elevator floor display detection, in particular to an elevator floor display detection device. Background technique [0002] Elevator manufacturing enterprises should carry out full-function inspection of the elevator human-machine interface during the production inspection of the elevator human-machine interface. After the elevator control system has completed the self-learning of the hoistway data, the inspection should be carried out in the normal express running mode. . [0003] At present, the elevator floor display is detected by the simulated elevator floor display signal data given by the original elevator system manufacturer. The signal is different from the actual elevator floor display signal, and communication anomalies often occur; go to the real elevator to collect and detect The elevator floor displays signal data. This method will affect the normal use of the elevator, resulting in inconv...

Problems solved by technology

[0003] At present, the elevator floor display detection is carried out through the simulated elevator floor display signal data provided by the original elevator system manufacturer. The signal is different from the actual elevator floor display signal, and communication abnormalities often occur; go to the real elevator on site to collect and test The signal data is displayed on the elevator floor. This method will affect the normal use of the elevator, and there are situations such as inconvenient operation and low efficiency.
