When the duration time information reaches or exceeds a preset second time threshold value, alarm indication information used for indicating that a trapped target object exists in the elevator is generated, and the alarm indication information is sent to authentication terminal equipment through a preset communication device.
In the embodiment of the application, when the two confirmation processes are detected, the elevator taking request instruction can be generated and sent to the instruction cache queue of the elevator for controlling the elevator to execute corresponding operation. Specifically, a pressure signal generated by pressing the elevator riding button is obtained as a first confirmation process. After the pressure signal is obtained, detection information aiming at a target detection area is obtained through an infrared detection device arranged in the elevator taking button, and the existence of the target object in the target detection area is judged to be used as a second confirmation process according to the detection information. When the target object exists in the target detection area, generating the elevator taking request instruction, and sending the elevator taking request instruction to an instruction cache queue in an elevator through a preset instruction sending device.
By adopting the elevator monitoring device based on the infrared detector, invalid elevator taking request instructions can be effectively identified in a secondary confirmation mode, unnecessary stopping of an elevator is reduced, the operation efficiency of the elevator is improved, and accordingly maintenance cost is reduced.
