HLSWT is independently developed, designed and produced by Zhengzhou Hengliang Technology Co., Ltd. It is mainly used for vehicle warning on curves, T-shaped or Y-shaped level crossings, cross level crossings and other occasions. It uses narrow beam radar to accurately detect vehicles in the blind spot of vision; wireless communication technology for dual-machine interaction; sound and light alarms for eye-catching prompts; cloud data upload platform interconnection. The safety warning terminal has the characteristics of active detection, active reminders, sound and light multiple alarms, cloud interconnection, etc., which can effectively reduce the occurrence of traffic accidents and perceive the road traffic status in real time.

System Process
As shown in above pic, the minimum system consists of a pair of road safety warning terminals and a cloud management platform. System workflow:
1. The terminal is powered by mains electricity/solar energy. When the millimeter-wave radar detects a vehicle approaching the blind spot, it automatically calculates the vehicle's speed and displays it in real time on the information board.
2. The terminal uploads the device location and detected vehicle speed to the management platform via the 4G network, allowing the center to perceive the traffic status of the traffic section in real time;
3. At the same time, the wireless communication unit is used to inform the opposite device that a vehicle is approaching;
4. The oncoming equipment uses sound and light alarms to alert oncoming vehicles, and text prompts are given on the information board at the same time.
System Features
1. Integrated structural design, beautiful appearance, long service life, easy installation and maintenance.
2. A variety of power supply methods to meet the needs of different scenarios.
3. Cloud interconnection supports remote display content modification, supports remote OTA, and provides data support for intermodulation.
4. The detection accuracy is high and the detection distance is long, up to 300 meters. Early warning reserves sufficient reaction time and reduces traffic risks.
5. Wireless dual-machine communication, low transmission delay and high perception sensitivity;
6. Sound and light stereo warning, 320mm*1600mm dual-color large screen display, tweeter, strong warning effect.
7. Supports vehicle speed detection, speeding judgment, and uses different color fonts for speed prompts.
