Device, translation interface and PLC controller are sequentially connected, PLC controller respectively with GPRS communication module, voice module, ac contactor
Device, steel wire braking, relay are connected with contactor；
Wherein, the laser displacement sensor is arranged on the ground between computer room and hoistway；The A.C. contactor with
Elevator runs circuit connection；The steel wire braking is mounted between traction machine and carriage.
Further, the contactor includes operation contactor and band-type brake contactor, operation contactor and band-type brake contactor
It is connect respectively with PLC controller.
Further, the relay includes layer door relay and gate relay, layer door relay and gate relay
It is connect respectively with PLC controller.
Further, the laser displacement sensor is LDM301 laser precision distance measuring velocity sensor.
Further, the PLC controller uses S7-200CPU224XP chip.
Further, the GPRS communication module uses MD720-3 module.
The invention has the following advantages:
(1) movement speed and present position information of carriage are monitored by laser displacement sensor, and by directly from fortune
Row contactor, band-type brake contactor, layer door relay and gate relay obtain elevator operation information, stored by PLC controller,
Collected information is analyzed, and drives A.C. contactor, GPRS communication module, steel wire braking and voice module movement, and
When stop carriage, notify administrative staff and pacify passenger in carriage；
(2) existing elevator structure is had no need to change, it is only necessary to signal is read from control element, it is appropriate to increase sensor and system
Stop component, can effectively detect accidental movement of elevator cage and takes measures to prevent accident；
(3) structure is simple, versatility is good.
Detailed description of the invention
Fig. 1 is structural block diagram of the invention.
Specific embodiment
As shown in Figure 1, lift car provided in this embodiment lifting monitoring device include elevator control cabinet, PLC controller,
Traction machine, wirerope, carriage and laser displacement sensor, be equipped in the elevator control cabinet operation contactor, band-type brake contactor,
