How to solve the difficulties encountered in the elevator display?

You can consider the way of three-dimensional display, the use of virtual reality means, the whole elevator into the form of a three-dimensional body, customers can freely observe the elevator from all angles, but also free to match the ceiling, floor, handrails and other parts, very intuitive, much better than the sample book, I have seen it in the Guangzhou exhibition, it seems to be called the elevator three-dimensional display system.

Now the elevator exhibition, it generally takes a few months to prepare! If you want to put a few elevators and escalators, the booth will be very large, and the rent will be expensive! Generally, there is a strong elevator factory, and the rented booths are very large, which is impressive The current elevator exhibition, I feel that it is the first business and elevator manufacturers to meet in the circle, and there are not many ordinary people who really visit.

There are really not many elevators advertised on TV stations, except for Shanghai Mitsubishi, which advertises on ** stations! Generally, elevator manufacturers set up billboards on the side of the highway.

To sell elevators well, or to have good sales channels (good relationship), ** business strong, these are the king! But the elevator has to be passable

Decorate an elevator model room next to the city where the elevator is sold, take your intended customers to see, understand your company's products through physical objects, have a visual impact, and have been used by many people for many years, which is more economical.

Take customers to visit the factory or model house.

Summary. Kiss hello <>

The elevator shows fault for more than 2 minutes: the single running time exceeds the set value. To put it simply, a single run, from start to stop, must be completed within the allotted time.

Procedurally speaking, that is, within the specified time, there must be a photoelectric signal from the leveling sensor to be input to the motherboard. The following phenomenon may occur: 1: The creeping speed of the inverter is set too low during multi-stage operation.

Phenomenon 2: The door area of the target floor is lost, resulting in too long a low-speed crawling time after the elevator speed change. Phenomenon 3:

Wrong number operation, unable to change speed to the target door area normally, low-speed crawling time is too long. Phenomenon 4: The section speed output relay is sticky, the zero speed cannot be given, and the crawling time is too long.

Phenomenon 5: The wire rope slips and the car is stuck, resulting in the elevator running time is too long. Phenomenon 6:

The motherboard over time is set to too small.

The elevator is more than 2 minutes to show a malfunction.

The elevator shows fault for more than 2 minutes: the single running time exceeds the set value. To put it simply, a single run, from start to stop, must be completed within the pickpocketing room at the specified time.

Procedurally speaking, that is, within the specified time, there must be a photoelectric signal of the sensitive car leveling sensor input to the motherboard. The following phenomenon may occur: 1: The creeping speed of the inverter is set too low during multi-stage operation.

Phenomenon 2: The door area of the target floor is lost, resulting in too long a low-speed crawling time after the elevator speed change. Phenomenon 3:

Wrong number operation, unable to change speed to the target door area normally, low-speed crawling time is too long. Phenomenon 4: The section speed output relay is sticky, the zero speed cannot be given, and the crawling time is too long.

Phenomenon bridge 5: wire rope slippage and car stuck, resulting in long elevator running time. Phenomenon 6:

The motherboard over time is set to too small.

How to fix it. The easiest way to judge the elevator fault is through the following steps:1

Observe the operating status of the elevator: First of all, it is necessary to observe the operating status of the elevator, including whether the elevator is operating normally, whether there is abnormal sound, whether there is any peculiar smell, etc. If there is an abnormal situation in the elevator, it is likely that there is a fault.

2.Press the elevator button to congratulate: If the elevator does not reach the designated Hongchun floor or cannot open the door, you can try pressing the button inside or outside the elevator to see if there is a response.

If there is no response, it is likely that the elevator is out of order. 3.Check the elevator display:

If the elevator is equipped with a display screen, you can observe the information on the display, including the current floor, elevator status, etc. If the information on the display is abnormal or cannot be displayed, it is likely that the elevator is out of order. 4.

Contact elevator maintenance personnel: If it is confirmed that the elevator is faulty, you need to contact the elevator maintenance personnel in time to deal with it. Before contacting the elevator maintenance personnel, the pants can stop the elevator and set up warning signs at the elevator door to prevent others from entering the elevator by mistake.

I wish you a happy life! Hope mine is helpful to you ha.

Although the floors of housing buildings are getting higher and higher, elevators have become very popular, especially for high-rise buildings, there is no elevator, or power outage, it will bring great inconvenience to travel, and the elevator as a precision, load-bearing equipment, in use is in need of regular maintenance, otherwise it is very dangerous if there is a failure, but the elevator has been used for a long time, it is inevitable that it will encounter failures, so what should I do if the elevator fails? Let's take a look with Qeeka Home experts.

1. What to do if the elevator fails.

If the elevator fails, you must first keep calm, if you think too much panic, it is difficult to save yourself, and then press the emergency alarm button in the elevator, and at the same time you can also try to call 100 to call the police or call relatives and friends**, during the rescue period, it is best to grasp the handrail of the elevator with your hands open, and squat down with your back against the elevator to avoid the elevator falling suddenly, resulting in secondary injury.

Second, what are the common faults of the elevator?

1. The elevator cannot close and open the door normally.

The elevator can not close and open the door normally, presumably many people have encountered, in this case must be reported to the elevator maintenance personnel in time for maintenance and elimination, it may be caused by the control circuit fuse is too loose, fused, etc., it needs to be tightened or replaced.

2. The elevator door does not open.

After arriving at the floor, the elevator door is not opened generally because the secondary door opening limit switch 2km damage caused by the door opening relay is not electrified, at this time it can be checked and determined by shorting two points, if it can open the door, it means that it is 2km damaged, so it needs to be replaced 2km on the line.

3. There is no response when you press the close button.

There is no response when pressing the door closing button, which is generally caused by poor contact and damage to the AGM contact, at this time, you can short-circuit two points for inspection and measurement, and choose to repair or replace according to the specific situation.

Summary: The above is an introduction to what to do if the elevator fails, I hope the content shared can give you some reference, if you want to know more about relevant knowledge, you can **** Qijia to consult.

Jumping up when you're about to hit the ground to reduce cushioning? This method is not advisable!

In the rapid fall of the elevator, people are in a weightless state in the car, and this environment is not something that can jump up if you want to. The point is that the elevator is already in a fault, the speed of the fall is very fast, you can't predict how many floors you will fall to, how high it is from the ground, so if you want to protect your own safety, this method will not work.

First of all, press the emergency call button first, don't panic and stay calm, and then press the button on the elevator floor from bottom to top in turn, maybe you can bring a little resistance to the fast-falling elevator, and choose to stay away from the corner of the door with your legs in a semi-bent state, and your head and back are close to the elevator wall, so that you can protect the cervical spine and the spine from injury when you fall to the ground.

What should I do if the elevator is out of service and trapped inside? This reaction is understandable, but you must calm down quickly, and don't be too afraid of panic to think, so as to prolong the time you are trapped.

First of all, press the call button first, looking for help from the outside world, and then press the buttons on each floor in turn, maybe the elevator will have some reaction, some trapped people will try to pry the door or hit the door, this way is not advisable, because you don't understand the situation outside, you don't know if the elevator stops at **, whether it will start again You don't know, so reckless behavior will bring safety hazards.

But you can bang on the elevator door to get the attention of people outside, and help you ask for help.

Be aware of unexpected situationsWhen taking the elevator, do not enter or exit immediately as soon as the elevator door opens, and be sure to check the outside environment first.

The elevator will generally not fail, but if there is a problem with the program, the computer software control system will issue an error instruction, so that there will be no floor and the door is open, then the passenger just subconsciously come in or out, then it will be dangerous.

Do not use your hands or feet and other body parts to block the elevator door at will, as this will interfere with the operation of the program and may trap yourself.

When the elevator is impacted, the push under abnormal circumstances, and the repeated back and forth pressing of the floor buttons will cause confusion in the instructions, thus affecting the normal operation of the elevator.

First of all, I want to stay calm. Then press the elevator alarm electricity. At the same time, call the elevator for help**. Wait patiently for repairs from the relevant personnel.

In case of this kind of failure, you should press the alarm button in time, you should ask the relevant departments for help, you should not panic, and you should save your physical strength.

If I encounter an elevator failure in the elevator, I will squat down first, turn on the light in my mobile phone, look for the rescue recorded in the elevator**, and try to keep myself calm.

Let the random variable yi=1 mean that the elevator stops on the ith floor, and yi=0 means that the elevator does not stop on the ith floor (i=1,2,......n)

e(yi)=1-(n-1/n)^r;The solution to the original problem is: i=1,,...n, the sum of all e(yi).

Self-rescue measures in case of elevator failure.

When the elevator runs out of order, passengers should not be impatient and panicked, and should use the alarm bell button, intercom device, communication, etc. in the elevator to call for help, or call the fault repair**, 110 alarm** for help; The elevator car is equipped with a ventilation device, which will not cause hypoxia, please wait patiently for rescue, the professional rescue team will rush to the rescue as soon as possible, do not take other self-rescue measures without authorization, so as not to cause unnecessary injury.

After the elevator stops and opens the door, when the car floor is 500mm higher than the floor floor, it is strictly forbidden to jump from the elevator.

Thanks for sharing. Remember: When you are trapped in the ladder, press the emergency spring delay first.

Alarm. After getting in touch with the monitoring personnel, Pick Chi Lee.

Waiting for help.

The problem of holding the brake is generally in the level, if it is in operation, the machine room will definitely have obvious odor and sound.

Generally, the jitter of elevators can be divided into electrical causes and mechanical causes. If the conditions permit, check whether the fault is transferred to the motherboard and inverter.

The main inspection of machinery in the hoistway includes the verticality and joints of the car guide rail, the situation of the car and the counterweight guide shoe, and the tension of the wire rope. The machine room is mainly the bearing of the main engine, whether there is abnormal sound, etc. Check whether the signal lines such as the wiring PG line are independent, and interference may also affect the operation of the elevator.

Traction pulley rope groove inspection, generally there is a problem here, and it will shake up and down.

Since your available conditions are not clear, such as load, balance factor, direction and frequency of jitter, machine usage, etc., I will give you a brief analysis first, I hope it will be helpful to you.

The message from the question "There is jitter on the downside, no on the upside." As long as you stand a few more people when going down, the elevator shake is significantly reduced."

1. The weight of the elevator car is light;

2. Your balance coefficient may be on the large side.

These two reasons may lead to the interstitial slippage of the traction steel rope in the wheel groove when the light load is going down, resulting in jitter. Recommendations:

1. Check the random documents and check the weight of the car. If it is light, you can add additional counterweight to the car.

2. Redo the balance coefficient after adding additional counterweight to the car.

3. Check whether the traction steel rope matches the traction wheel groove (the nameplate of the host is recorded)? Whether the traction steel rope is hung correctly (1:1 rewinding method. Note that the same traction rope passes through the traction wheel twice times)?

If there is no problem with the balance factor, then you press down the main frequency of the inverter to see if it is still shaking, I think the downward jitter, most of the reason is that your inverter parameters are not set properly, refer to the debugging outline to compare, it should be solved.

Adjust the tension of the wire rope to make the balance coefficient.

The weight of the car is a little small, and the idea is to increase the weight of the car (such as installing a counterweight at the bottom of the car) and then readjust the balance factor.

There is also to adjust the parameters of the inverter, the load of the uplink motor is small, the load of the downlink motor is large, and the output current is large. Do you test the uplink again with a full load to see if it jitters? According to what you said, it will definitely not shake when it goes down with full load, and the effect is good, and if it also shakes when it goes up with full load, you need to adjust the parameters of the inverter.

I have encountered a bad encoder cable, it is the twisted pair cable that the OEM is not good, and then it is good to replace the encoder cable of the new Shida!!

There are many reasons for jitter, the gap between the rails is too large, the counterweight is too heavy, and other factors, maybe the parameters are wrong.

The first question: first Chunye rent press 3, 3, 8 are recorded, pick up Zhao to the eighth floor, 3 and 8 are sold number, then press 3, and then record 3, the elevator down, to the ridge town is not to press 3 first, to the eighth floor and then press is the same.

The second problem: the elevators now close automatically.
