In recent years, with the rapid development of the warehousing and logistics industry, there is an increasing demand for forklifts in factories, ports, docks, and logistics companies. The subsequent forklift accidents are also on the rise. Forklifts are heavy-tonnage transportation equipment in warehouses. Because the goods in front block the sight of operators, there are many visual blind spots. In the event of a vehicle collision, it is easy to hit people or hit the shelves and cause the goods to collapse and hurt people. Forklift collision avoidance is imperative! The responsibility for safe production is more important than Mount Tai. Doing a good job in forklift collision avoidance is the primary task of safety protection in the factory area. The editor of this article will share with industry customers the UWB TWR two-way ranging personnel forklift anti-collision solution that effectively prevents and eliminates high-risk accidents such as forklift-forklift collisions and forklift crushing workers .
UWB TWR two-way ranging scheme
The hardware composition of the scheme: it is composed of UWB base station (plus base station power supply, sound and light alarm device, etc.), UWB label (work card) and so on.
working principle:
Install UWB base station VDU2506 and sound and light alarm device on the forklift to form an anti-collision warning device. Personnel wear matching UWB anti-collision work card VDB1501R . Through the high-precision distance measurement between the UWB base station installed on the forklift and the UWB work card worn by the personnel, the precise distance measurement between multiple forklifts and the precise distance measurement between multiple personnel and the forklift can be completed at the same time. Realize the anti-collision warning between forklifts and forklifts, forklifts and personnel.
At the same time, the UWB base station can set the ranging range and early warning threshold according to the scene . When the distance between two forklifts is lower than the set safety warning threshold , the UWB base station outputs a control signal to the relay after measuring the distance with another UWB base station, and then controls the alarm and the power supply of the forklift itself, thereby realizing sound and light. Alarm and emergency braking .
Advantages of UWB TWR two-way ranging solution
1. Precise ranging: The
two-way ranging accuracy is as high as 10 cm, and the error is small;
2. Long-distance coverage:
The two-way ranging between the base station and the base station can reach 500 meters, and the ranging range can be set according to the actual use scene;
3. The early warning threshold can be adjusted Setting
The early warning threshold can be set according to the actual usage scenario;
4. The 360° no dead angle UWB
base station can realize 360° no dead angle real-time ranging, which is not affected by various bad weather and dust ; Area electronic fence, enter to trigger the corresponding level of alarm.
Application scenario of UWB TWR two-way ranging solution
1. Forklift and personnel anti-collision warning
Due to the occlusion of the line of sight, the driver failed to discover the existence of the staff in time. The UWB base station can sense the presence of the staff wearing the work card and the forklift with the UWB base station installed, so as to realize the early warning.
2. Forklift and forklift anti-collision warning
The UWB base station on the forklift measures the distance with the UWB base stations on other nearby forklifts, and outputs control signals to the relay to control the alarm and the power supply of the forklift itself, so as to realize sound and light alarm and emergency braking.
Anti-collision warning solution for people and forklifts based on UWB TWR technology. SKYLAB can provide hardware products and software support such as long-distance UWB base stations, UWB work cards, and UWB safety helmet labels in forklift anti-collision solutions .
