Bridge crane, also known as crane/crane, is a lifting equipment for lifting materials in the workshop, warehouse and yard. When the bridge machine works, it needs to move the cargo back and forth on the track. Most of the plant bridge machine tracks will use multiple machines to cooperate with the operation. Collision between bridge machines is inevitable, and the mechanical limit anti-collision warning distance is too short, and disrepair will lead to collision between adjacent and upper and lower tracks during bridge machine operation, resulting in accidents.

As an important equipment in modern industrial production, driving car has a wide variety of types and large usage, which is widely used in industrial and mining enterprises. It is often used in indoor and outdoor warehouses, factories, docks and open-air storage yards. In the same building, the same floor, the upper and lower floors, or the upper, middle and lower three floors are set up track crane, because the scheduling is not easy, prone to collision accidents, resulting in life threat and property loss of operators.

The intelligent driving anti-collision device will automatically detect the position of the driving, and when the driving runs to the warning area (that is, set the upper limit or set the lower limit), the system will send out sound and light warning signals. At the same time, the system will output the control signal remotely to force the brake to ensure the safety of driving operation. As advanced safety protection equipment. Laser ranging sensor is widely used in intelligent driving anti-collision system, which is also the key point of the system.

Intelligent driving anti-collision device based on SK-Pro series laser ranging sensor

The maximum range of SK-Pro series is 200m, and the absolute accuracy is ±1.0mm. CAN withstand up to 100,000 lux of ambient light, equipped with RS-232, RS-485, SSI, CAN BUS, 4~20mA,0 ~10v analog interface. With its outstanding product performance and operation performance is widely used in modern logistics transportation, automobile manufacturing, food production and other industrial fields. The intelligent driving anti-collision device based on SK-Pro series laser ranging sensor includes driving body, SK-Pro series laser ranging sensor, special laser reflector, industrial all-in-one machine, data acquisition and control unit and sound and light alarm.

The SK-Pro series laser ranging sensor is installed on the main beam of the driving body, and the special laser reflection plate is installed on the side wall of the workshop and the driving body. Data acquisition and control unit, industrial all-in-one machine and sound and light alarm are installed in the control room of the driving body. The signal output end of SK-Pro series laser ranging sensor is connected with the signal input end of data acquisition and control unit, and the data acquisition and control unit is also connected with the industrial all-in-one machine and sound and light alarm respectively.

In the process of driving in the workshop, SK-Pro series laser ranging sensor sends out laser ranging signal. If the front of the driving is close to other relatively driving crane or side wall, the special reflector set in the driving body or side wall will reflect the laser signal back to SK-Pro series laser ranging sensor. After the sensor receives the reflected laser signal, it transmits the received reflected laser signal to the data acquisition and control unit. According to the time difference between the laser emission time and the receiving time, the data acquisition and control unit calculates the distance between the two adjacent vehicles or the distance between the vehicle and the side wall. When the distance is less than the safe distance, the data acquisition and control unit will prompt and alarm on the industrial integrated machine, and also warn the driver to brake urgently through the sound and light alarm to avoid collisions. The anti-collision device based on SK-Pro series laser ranging sensor has reliable structure, stable communication transmission, convenient operation and maintenance, and also reduces the special operator, improves the work efficiency of the workshop, and saves the labor cost.

Two SK-Pro series laser ranging sensors can be symmetrically installed on both sides of the main beam of the driving body, and the relative position distance of both sides of the main beam can be monitored respectively. When the SK-Pro series laser ranging sensor on one side of the driving body monitors that the adjacent distance is less than the set safe distance, The data acquisition and control unit can verify according to the monitoring data on the other side to verify whether the fault of the data acquisition and control unit or the fault of one of the sensors is the false alarm, which reduces the probability of false alarm and makes the monitoring data more accurate.
