And then the elevator is controlled to run, and the electric switches of all tests are controlled by the self-triggering device 7, so that the detection of all the electric switches, the speed limiter, the safety tongs and other components is carried out one by one.

3. And (3) traction performance test:

Specifically, whether the elevator can safely and reliably run has two important aspects: traction performance and braking performance of an elevator. It relates to the full life cycle of elevator products, is an important safety measure, is interactive, indivisible. Whether traction and braking performance are effective or not is a key link to ensure that an elevator control system, an operation instruction, and the like can be reliably executed, and is also an important influencing factor of riding comfort.

The traction force of the elevator is derived from the friction force between the traction steel wire rope and the sheave groove of the traction sheave, the traction performance ensures the safety of the elevator dynamics, is the most basic condition that the elevator can run, and has to provide enough traction force when the elevator car is loaded and stopped. The braking performance is to ensure the safety of the elevator in a static state and ensure that the elevator can reliably and stably stop at a target determined position, so that the brake is the most important component for realizing reliable braking of the elevator. In recent years, the accident of injuring people of the elevator caused by the potential safety hazard of the brake is frequent, and the inspection of the safety state of the brake of the elevator is strengthened. Braking capability is the final embodiment of the technical condition of the elevator brake, and checking of the braking capability is an indispensable technical means for preventing personnel injury caused by elevator sliding.

The application of braking performance of the elevator is mainly that whether the braking force is applied is proper or not, if the braking force is insufficient, the deceleration is small, the braking distance is too large, the elevator cannot be effectively braked, the elevator is in out of control (top-rushing, bottom-squatting, door-opening and car-sliding and the like), and the longer the duration time is, the more dangerous is caused; if the braking force is too large, the deceleration is large, the braking distance is too small, the impact force is large during braking, and even the personal injury of passengers in the car is caused by the too large impact force during braking. If the two performances are problematic, serious casualties such as ladder slipping, roof punching, squat, shearing, extrusion and the like and equipment body damage can be caused.

In the test of this embodiment, the traction performance test of the elevator is completed by the master controller 1, the positioning device 6, the monitoring and identifying device 5, the elevator driving and measuring device 2 and the elevator running performance acquisition device 3.

The test process comprises the following steps: the elevator is repaired and ascended, the limit switch and the buffer switch are triggered successively, short-circuit failure operation is needed to be carried out on the switches, and then the elevator is repaired and ascended continuously. The judgment indexes of the traction performance of the elevator are as follows: the car cannot be lifted further when the counterweight of the elevator fully compresses the buffer, the hoisting machine slips or does not rotate (by means of the positioning device 6 and the elevator drive measuring device 2 together).

The braking performance test scene of the elevator is completed by the aid of the master controller 1, the positioning device 6, the self-triggering device 7, the monitoring and identifying device 5, the elevator driving measuring device 2 and the elevator running performance collecting device 3.

The test process comprises the following steps: the normal speed of the elevator goes up and down, reaches a preset position (judged by the positioning device 6) to trigger the stop switch (the self-triggering device 7 realizes the triggering action). The judgment indexes of the braking performance of the elevator are as follows: the elevator car finally stops (the master controller 1 is discriminated by the collected data of the positioning device 6 and the elevator drive measuring device 2), and the drive main machine stops (the master controller 1 is discriminated by the collected data of the elevator drive measuring device 2).

The elevator inspection comprehensive monitoring management method provided by the embodiment further comprises the following steps:

the method comprises the steps of establishing a data model information database 8 of an elevator hoistway, intelligently comparing and analyzing data model information acquired in real time with information of the data model information database 8 based on an intelligent analysis algorithm, and carrying out alarm prompt when any super-parameter change of an entity in the hoistway is found, and transmitting the alarm prompt to a monitoring terminal (such as a mobile phone, a computer and the like) of a worker in a wireless mode by a master controller 1.

Specifically, drawing and confirming a hoistway diagram of an elevator are necessary skills of a construction unit, and can be measured, tested and accurately measured, so that the subsequent design, installation and manufacturing processes can be smoothly carried out. The safety accident of the elevator falls into a hoistway and the shearing of a door zone is the most dangerous accident, and the emergency rescue after the accident is particularly important, so that the state of the hoistway of the elevator is required to be monitored, and the early warning is provided when the entity of the hoistway is found to be changed.

Based on a three-dimensional laser scanning technology and a 3D depth camera (namely a depth camera device and SLAM simultaneous localization and mapping technology), a three-dimensional model is built for key information in an elevator hoistway in real time, and the accuracy and the error of the three-dimensional model are verified within an acceptable range by combining the existing measurement technology means. An elevator shaft model information database 8 is established, based on an intelligent analysis and judgment algorithm, the data model information acquired in real time is intelligently compared and analyzed with library source information, and when any super-parameter change occurs to an entity in a shaft, alarm prompt is carried out and the alarm prompt is wirelessly transmitted to a handheld terminal 21 of related personnel, so that necessary technical means are provided for better performance responsibilities of production units, inspection and monitoring institutions.

Therefore, the elevator inspection integrated monitoring management method provided by the embodiment can carry out multi-azimuth intelligent inspection work on the elevator, can carry out accurate detection work from the well of the elevator to the car of the elevator, can effectively maintain the elevator, avoid errors caused by manual inspection, and ensure the safe use of the elevator.
