How to operate the playground sensor safely

Sensors are everywhere in life, and this will be an instrument people will see everywhere in the future. The sensor can be said to be more convenient for people's lives to travel, but sensor performance problems, sensor quality issues, and sensor safety issues, etc., all of which will also be a concern.

Yesterday, the Shanghai Happy Valley roller coaster project “Gumu Long” appeared on the alarm and stopped twice, causing the vehicle to stop about 20 meters from the lift. Happy Valley’s maintenance personnel immediately arrived at the fault site after receiving an alarm from the operator. At the same time, the tourists were evacuated. About 3 minutes, 24 tourists on the roller coaster all safely evacuated to the ground and there were no casualties. According to the preliminary investigation results, the cause of the accident was an alarm shutdown due to an abnormal brake sensor of the equipment, which was not directly related to hot weather.

This is also through the investigation of the maintenance personnel. The cause of the malfunction is the sensor abnormality, which caused the system alarm and protective shutdown. After the reasons were ascertained, the maintenance personnel immediately repaired and replaced the accessories and opened the project at 3:30 pm after repeated testing. Visitors received no abnormalities after the operation.

It can be said that this time, the sensor safety problem has once again aroused people's concern. The device is the first wooden roller coaster in China with a track length of 1,165 meters and a height of 33 meters. It can ride 24 people in a single ride and has a maximum operating speed of about 90 per hour. Kilometers. The device has had several similar "snaps" phenomenon, basically all of them are "Gumou Dragon" automatic alarm shutdown, which belongs to the project security early warning automatic protection device start. Here the sensor not only causes accidents, it is also a necessary equipment to protect people's safety. After all, the sensors on this equipment I think must be perfect.

All the equipment in Happy Valley Park was put into operation after being tested by the national and Shanghai special equipment inspection agencies. At the same time, it also has a complete set of weekly, monthly, and annual inspection systems, as well as regular safety emergency drills. The sensitivity of this brake sensor is set according to the relevant standards of the national special equipment. The more sensitive it is, the more it is to protect the safety of tourists, so we will not adjust this setting after replacing the accessories. I hope all this is in accordance with the description of the relevant personnel, or such consequences are unimaginable. At the same time, manufacturers of all sensors should understand that the quality of the sensor can never be sloppy.
