Applications

Elevator space occupancy detection refers to the use of sensors and other technical means to monitor the number of people and items in the elevator to ensure the safe operation and use of the elevator environment.

The sensor can be installed inside or outside the elevator to judge the occupancy of the elevator space by measuring the number of people, weight, volume and other parameters in the elevator. When the number of people or items in the elevator exceeds the carrying capacity of the elevator, the system will sound an alarm and restrict the use of the elevator. At the same time, the system can also be tested according to the purpose of the elevator, for example, the hospital elevator can detect the amount of patients transported to ensure the safety of patients and their equipment.

Elevator space occupancy detection can effectively avoid failures and accidents caused by overloading of people or items in the elevator, ensure the smooth operation and safe use of the elevator, and play an important role in safety assurance.

LiDAR can be applied to the occupancy detection of autonomous elevators and intelligent elevators in the detection of elevator space occupancy. Lidar can create a three-dimensional map of the elevator by emitting a laser beam and measuring its reflection time and location. The position and contour information of human body, objects and other obstacles detected by lidar can be transmitted to the elevator control system in real time, and the number of people and items in the elevator can be automatically identified according to the load capacity and space specifications of the elevator, and the space occupation in the elevator can be intelligently judged.

When the lidar detects that the elevator space has reached or is close to the elevator's load capacity, it can sound an alarm and prohibit new passengers or items from entering the elevator to prevent the elevator from being overloaded. At the same time, when abnormal situations occur in personnel or items, such as falling or overturning, the system will also send out an alarm in time and take corresponding measures to reduce the risk of elevator use.

The application of lidar in elevator space occupancy detection can make the elevator further realize the goals of automation, energy saving, intelligence, and safety, improve the efficiency and use experience of the elevator, and also provide the elevator management with a high-precision way to obtain elevator use data for easy elevator maintenance and management.

The advantages of LiDAR in elevator space occupancy detection are mainly reflected in the following aspects:

1. High precision: LiDAR can accurately measure the number of people and objects in the elevator, and can automatically identify the category and shape of objects in the elevator, so as to more accurately judge the space occupation of the elevator.

2. Fast measurement: LiDAR is able to scan all objects in the elevator in a very short time, so as to achieve fast and accurate elevator space occupancy detection.

3. Reliability: LiDAR has extremely high stability and reliability in elevator space occupancy detection, and is not affected by external environments such as temperature or humidity, and can accurately detect in various complex environments.

4. Automation: LiDAR can automatically analyze and identify the number of people and items in the elevator, so as to realize the automatic detection and control of the elevator space occupation, and facilitate the real-time monitoring and management of the elevator management.

5. Safety: LiDAR can detect the number of people and items in the elevator in real time, and send out alarms in time to avoid overloading the elevator or other dangerous situations.

6. Customizable: LiDAR has high customization ability, and can be customized according to the specifications and uses of elevators to meet the special needs of different elevators.

In summary, LiDAR has significant advantages in elevator space occupancy detection, which can improve the safety and efficiency of elevator operation while reducing the workload of elevator management.
