Elevator space occupation 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.

Sensors can be installed inside or outside the elevator to determine the occupancy of 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 detected according to the purpose of the elevator, for example, hospital elevators can detect the volume of patient transport to ensure the safety of patients and their equipment.

Elevator space occupation detection can effectively avoid the failure and accident caused by the overload of personnel or items in the elevator, ensure the smooth operation and safe use of the elevator, and have an important safety guarantee role.

Lidar can be applied to the occupancy status detection of automatic driving elevators and intelligent elevators. Lidar can create a three-dimensional map of the elevator by firing a laser beam and measuring the time and location of its reflection. The position and contour information of obstacles such as human body and objects detected by LiDAR can be transmitted to the control system of the elevator 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 situation in the elevator can be intelligent judgment.

When the Lidar monitors that the elevator space has reached or is close to the load capacity of the elevator, it can issue an alarm and prohibit new passengers or items from entering the elevator to prevent the elevator from overloading. At the same time, when personnel or items occur abnormal conditions, such as falling or tipping over, the system will also send an alarm in time and take appropriate measures to reduce the risk of elevator use.

The application of Lidar in the detection of elevator space occupation can make the elevator further realize the goals of automation, energy saving, intelligence, safety, etc., improve the efficiency and use experience of the elevator, and also provide the elevator manager with a high-precision way to obtain elevator use data in order to facilitate elevator maintenance and management.

The advantages of Lidar in the detection of elevator space occupation 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 categories and shapes of objects in the elevator, so that it can more accurately judge the space occupation of the elevator.

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

3. Reliability: Lidar has high stability and reliability in the detection of elevator space occupation, which is not affected by external environment such as temperature or humidity, and can be accurately detected in a variety of 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, which is convenient for the elevator manager to carry out real-time monitoring and management.

5. Safety: Lidar can detect the number of people and items in the elevator in real time, and issue alarms in time to avoid elevator overload or other dangerous situations.

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

In summary, Lidar has significant advantages in the detection of elevator space occupation, which can improve the safety and efficiency of elevator operation, and reduce the work burden of elevator management.
