August 18, Xiamen Lake Xinghu Road  Xiangyu Garden took place with an elevator accident, the elevator crazy jump, 1 year old baby fell to his death. The accident once again aroused concern about elevator safety.  Elevator control system disorder how to do?  What should I pay attention to? ... ... this issue, "product quality testing laboratory" into the Provincial Quality Supervision Bureau special inspection hospital, simulation elevator failure, and asked the hospital vice president Lin Yao analysis of reasons and precautions. At the same time, Lin Yao also revealed that the  "Fujian Province Elevator Safety Management Measures" will be formally implemented on October 1, elevator safety management approach has never been before, it is to solve the old elevator security risks play a positive role.

Experiment 1 elevator screen garbled, key not working, when the ladder when we supposed to do

Simulation failure:  When you take the elevator, there are calls,  outside the call does not show, or the program garbled, the button did not respond, ladder (slow down the elevator), the following test can be used to test the reasons.

Laboratory equipment: elevator comprehensive performance test laboratory (including control systems, drive systems, virtual wells, variable frequency analog load system, software analysis system).

Experimental steps: first remove the faulty elevator control panel, placed in the elevator comprehensive performance test laboratory, the control panel connected to the control cabinet, commissioning, elevator loading operation, and then test analysis.

Test results: 1. Control panel on the original device aging, the emergence of procedural disorder phenomenon; 2. Flat sensor failure, there are ladder and so on.

Emergency treatment: the elevator may be on the next run, then passengers do not panic, this is the elevator in accordance with the instructions set automatically address, once found will stop, the elevator door open, the passengers should immediately leave. These actions can not have:

1. When calling the elevator, do not press the up and down buttons at the same time;

2. Do not beat, tap or hit the operator panel with a hard object;

3. Do not jump in the car;

4. Do not crowded out of the car;

5. Do not stay for a long time at the car entrance;

6. Prohibit the unauthorized dismantling of the elevator car, outside the station parts and ancillary facilities for repair;

7. Do not use the unusual means to open the elevator floor door or car door;

8. Do not take more than the rated load of the elevator.

Experiment 2 When the elevator suddenly falls, it will stuck in a layer

Simulation Failure: When you take the elevator suddenly fall, you can use the following test to test the reasons.

Experimental apparatus: speed limiter test bed.

Analysis: elevator speeding, it will enable the speed limiter, safety gear action. Speed ​​governor electrical switch action, the brake will automatically brake, mechanical action, it will start the safety gear action, safety clamp will be stuck in the rail, the elevator stopped. If there is a drop, you can carry the instrument to the scene to detect the speed limiter, safety gear. If the speed limiter is not detected within 2 years, or the speed limiter, the safety gear has been changed, can also be used to detect the instrument.

What is the elevator stuck in the floor?

1. Do not panic, you can use the car with alarm button or phone call for help, in accordance with the provisions of the bell can reach the duty room, 24 hours are on duty, and require maintenance personnel in half an hour to reach the scene;

2 cars and wells well ventilated, adequate air, the elevator has a number of passengers to ensure safety measures, please be patient waiting for the rescue;

3. Do not attempt to leave the elevator through other dangerous ways,  and do not force the elevator door to open.

Experiment 3 elevator door switch too fast or not the reason is why

Simulation failure: When you take the elevator, found the elevator door can not be closed, or open the door too fast, the following test can be used to test the reasons.

Laboratory equipment: separable elevator door system.

Experimental steps: Collect the fault content of the elevator door system, put on the experimental equipment, the door system failure simulation analysis.

Analysis of the reasons: improperly set the parameters of the door control system, the door by foreign body jamming and other reasons, may lead to open the door too fast or slow. In general, the width of the door to open with B, B ≤ 800 mm, the sub-automatic door switch door time should not be greater than 3.2 seconds, next to the automatic door switch door time should not be greater than 3.7 seconds; 800

To prevent the door system to destroy these acts can not have

1. Do not kick the door, so as not to damage the floor;

2. Do not try to stop the car door by hand, foot or crutches, sticks, sticks and other items;
