Technical features and measures
Mechanical technical characteristics
Flexible interception
The flexible interceptor adopts advanced synthetic materials in China. When the vehicle collides with the interceptor, it can fully protect the vehicle and avoid vehicle damage. The breaking force of the flexible interceptor is 300KN.
Flexible cushioning
The flexible energy absorption device adopts multi-stage buffer energy absorption structure, uses advanced elastic materials and pressure plate energy absorber to transform the impact energy of rubber tyred vehicle into elastic deformation of flexible elastic material and friction energy of energy absorber device, so as to achieve the effect of multi-stage flexible buffer braking.
Adjustable energy
The interception energy of each stage of energy absorber is adjustable, and the energy absorption of each stage of energy absorber can be reasonably set according to the type and weight of intercepted vehicles to realize flexible interception of different vehicles;
Controllable distance
According to the type and weight of intercepting vehicles, the energy of each stage of energy absorber can be adjusted, so that the interception distance of each vehicle can be controlled. Specifically, the vehicle can be braked within the reasonable distance required by the mining party.
Easy to install
In the process of construction and installation, on the premise of not refitting vehicles and occupying the driving space of roadway, the installation of mechanical part is simple and convenient. Only the buffer energy absorption device is installed on the two sides of the roadway, and the flexible blocking device and actuator are installed on the roof of the roadway.
Electrical technical characteristics
Equipment self diagnosis
In order to solve the problems of daily monitoring and maintenance of equipment. The system can monitor the running state of key equipment such as vehicle controller and obstruction controller, so as to realize self diagnosis of equipment.
The timing task is set by the system software, and the operation status data (such as power on state, communication state, execution state, etc.) of key equipment such as vehicle mounted controller and obstruction controller are collected actively. The collected data are uploaded to the server software for analysis, early warning and display. At the same time, the early warning information is timely pushed to the relevant staff, so that the staff can master the operation status of the equipment in real time.
Communication double guarantee
In order to improve the stability and timeliness of communication in the electrical part, the dual communication guarantee with 4G communication as the main communication and Lora communication as the auxiliary is adopted.
Take the vehicle transmitter as an example
