Overhead cranes, also known as cranes/overhead cranes, are lifting equipment that is used to lift materials over workshops, warehouses and stockyards. When the bridge crane works, it needs to move back and forth on the track to lift the goods, and most of the plant bridge crane tracks will use multiple machines to cooperate with the operation. It is inevitable that collisions will occur between bridge cranes, and the mechanical limit collision avoidance warning distance is too short, and disrepair will lead to collisions between adjacent and upper and lower rails, resulting in accidents.

As an important equipment in modern industrial production, the crane has a wide variety and large use, and is widely used in industrial and mining enterprises, often used in indoor and outdoor warehouses, workshops, wharves and open-air storage yards. In the same building, in the case of rail-running cranes on the same floor, upper and lower floors, or upper, middle and lower floors, due to the difficulty of scheduling, collision accidents are prone to occur, resulting in the life threat of operators and property losses.

The intelligent driving anti-collision device will automatically detect the position of the vehicle, and when the vehicle runs to the warning area (i.e. set the upper limit or set the lower limit), the system will send out an audible and visual warning signal. At the same time, the system will remotely output the control signal and force the brake to ensure the safety of driving. As an advanced safety protection device. Laser ranging sensors are widely used in intelligent driving anti-collision systems, and they are also the key to the system.

Based onSDC series laser distance sensor intelligent driving anti-collision device

The SDC series has a maximum range of 200 m and an absolute accuracy of ± 1.0 mm. It can withstand ambient light up to 100,000 lux and is equipped with RS485/RS422/4-20mA/switch/Canbus/SSI/Ethernet/Profinet interfaces. With its outstanding product performance and operational performance, it is widely used in modern logistics and transportation, automobile manufacturing, food production and other industrial fields. The intelligent driving anti-collision device based on the SDC series laser ranging sensor includes the driving body, the SDC series laser ranging sensor, the special laser reflector, the industrial all-in-one machine, the data acquisition control unit and the sound and light alarm.

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

In the process of driving in the workshopThe SDC series laser distance sensor emits a laser ranging signal, and if the front of the vehicle is close to other overhead cranes or side walls that are coming from each other, the special reflector plate set on the driving body or side wall will reflect the laser signal back to the SDCSeries laser ranging sensor, after the sensor receives the reflected laser signal, the received reflected laser signal is transmitted to the data acquisition control unit, and the data acquisition control unit calculates the distance between the adjacent two driving bodies or the driving and the side wall according to the time difference of the laser emission time and the receiving time. When the distance is less than the safe distance, the data acquisition control unit will prompt an alarm on the industrial all-in-one machine, and at the same time, it will also warn the driver to brake urgently through the sound and light alarm to avoid collision. This kind of driving anti-collision device based on SDC series laser ranging sensor has reliable structure, stable communication transmission, convenient operation and maintenance, and also reduces special operators, improves the work efficiency of the workshop, and also saves labor costs.

Two units can be usedSDC series laser ranging sensor is symmetrically installed on both sides of the main beam of the driving body respectively, can monitor the relative position distance of the main beam of the driving body on both sides respectively, when the SDC series laser ranging sensor on one side of the driving detects that the adjacent distance is less than the set safety distance, the data acquisition control unit can be verified according to the monitoring data of the other side, Check whether it is a false alarm caused by the fault of the data acquisition control unit or the fault of one of the sensors, reduce the probability of false alarm, and make the monitoring data more accurate.
