How to avoid the elevator injury incident no longer occurs

Elevators and our lives are inseparable, living in the city, it is difficult to imagine if there is no elevator what.

Recent news are concerned about an elevator injury incident, news and comments is nothing but blame shopping malls, blame elevator maintenance, blame manufacturers, discuss elevator industry and so on public opinion level.

How to completely solve the elevator hurt people, so that the incident can not happen again?

The social public opinion one-sided "the management level", namely enhances the mall service consciousness, the staff engagement degree and so on, but these factors are not controllable. In the present celestial kingdom is extremely unreliable.

Another is the "technical level", through technical means to solve the elevator safety problems. It seems to me that this incident was caused by an elevator design flaw.

Elevator wounding incident Solution

Now let me talk about the technical level of "elevator wounding incident solution".

First in the elevator cover under the installation of a pressure switch, when the cover plate is installed, the switch is under pressure, circuit conduction, through the relay, open the elevator power.

Once the cover is opened, the elevator immediately stops powering. Further extends the function, when the cover plate is opened, stops the elevator power supply, and simultaneously triggers the breaking.

What do you think? Cost less than 5 yuan, installed two parts to completely solve the security problem, in the existing elevator equipment modification, only a few hours to complete.

This technology-level solution is far better than the "management-level solution" that media/public opinion expects.

We can make technical improvements in many aspects, install a variety of sensors, to achieve real-time monitoring of working conditions, fault alarm, automatic response and so on.

The following points need to be addressed today:

Real-time monitoring

At present, elevators are inspection once a year, the use of problems in the process to find manufacturers above maintenance. Such a check is far from enough, often elevator problems, light people trapped in it, the heavy will hurt people.

For example, we can monitor elevators with many sensor technologies:

1. Elevators are safe, many elevators now have to prevent the function of the clip, old-fashioned through the limit switch the kind of gradual elimination, the new basic use of light sensor, I have encountered several failures, such as repeatedly unable to close the door. I think there may be a lot of improvements, such as repeatedly closing more than three times to send an alarm, stop the elevator operation.

2. Infrared space sweep anchor, when the elevator stopped running (unmanned ride), scanning elevator indoor heat source, heat source for more than 5 minutes, issued an alarm. This may be the case when the child is trapped or the old man fainted.

Remote monitoring

Remote monitoring means the data collected by the elevator sensor, which is sent to the manufacturer in real time or regularly for data analysis and archival backup.

Fault Alarm

At present the main rely on people to judge the fault, and then decide whether to notify the vendor repair.

With the above monitoring data, the elevator fault manufacturers know the first time, and home repair.

Even manufacturers can collect the monitoring data, through the technical staff analysis, decide whether to remotely close the elevator.

Automatic response

Is the elevator intelligent sign, the elevator can according to the pre-set procedures, to minor faults, to make automatic response. As mentioned above, "Elevators are safe", "infrared space sweep anchor".

Elevator industry should introduce 4S concept

At present the elevator market is very chaotic, I think the elevator industry should introduce 4S concept.

4S is a set of sales (Sale), spare parts (Sparepart), after-sales service (service), information feedback (Survey) Four in one of the sales enterprises.

Let the elevator sales, accessories, after-sales maintenance, as well as the problem of feedback flow, standardization.
