Vehicle break-in alarm equipment at traffic accident site
System overview
This equipment can effectively prevent the occurrence of secondary accidents when handling the scene of traffic accidents, and is a barrier to ensure the safety of police officers at the scene. De'an technology independentresearch and development of anti-break-in alarm equipment, the use of extremely simple, anti-break-in alarm equipment, only need to remove the alarm detection ring from the main equipment, placed on the front tapered at the scene of the accident.When a vehicle breaks into the scene of the accident, such as touching the cone or entering the infrared detection area alarm detection ring to issue a wireless alarm signal, the rear-end main equipment and the portable alarm received the alarm signal, sound and light and vibration to alert, prompting police officers at the scene to avoid accidents in a timely manner.
Second, equipment characteristics and advantages
1. Easy to carry, simple to use, layout of anti-break-in site only 1-3 minutes.
2. The work is safe and reliable, the alarm is only 0.02 seconds late, which is equivalent to synchronous triggering.
3. Communication distance is far, straight line distance up to 1000 meters, you can use the relay to increase the communication distance.
4. Alarm detection ring ultra-low power design, a full charge can work continuously for more than 100 hours, enough to meet the needs of long-term field work.
5. Unlimited transmission using 433MHz industrial band, strong anti-jamming ability.
6. The main device is not only the carrier of the alarm detection ring, but also its charger, this design maintenance is simple, flexible use, compact structure, and truly realize the fool-like operation.
Third, the function of the device
1. Consisting of alarm detection ring, preset cone (provided by user), main box high-power alarm and hand-held wireless alarm controller, far-sighted warning light.
2. Alarm detection ring can be detected through vibration, displacement, infrared detection, through intelligent judgment and wireless digital transmission technology, for various reasons into the warning area of people or motor vehicles, detection distance of 0.1-6 meters.
3. Can take the initiative to prevent sound and light warning in advance, alert people or motor vehicles to break in, remind the driver of the vehicle to take prompt measures to brake the vehicle to avoid accidents.
4. Can send a wireless warning signal to trigger the scene of each police officer wearing the sound, light hand-held wireless alarm controller, prompting the scene staff to quickly evacuate the scene, to avoid the intrusion into motor vehicles injured incidents and secondary accidents.
5. Can trigger the field wireless high-power alarm, prompting other non-wearing sound, light-hand wireless alarm controller on-site personnel to avoid breaking into the vehicle and quickly evacuate to safety.
6. Use: outdoor use, portable alarm, wireless networking, wireless transmission reception and control, high-power alarm.
7. Working mode: alarm detection trap placed on the preset cone on the road surface automatically work, no need to look after.
8. Early warning mode: infrared active warning, collision and displacement passive alarm, alarm sound control output.
9. Equipment material requirements: alarm detection ring using PC, PE polycarbonate high-strength engineering plastic, hand-held wireless alarm controller using ABS high-strength plastic, durable.
10.Network range: wireless network ingress.
11. Wireless alarm transmission receiving distance: active warning ring body of 1000 meters;
12. Alarm detection ring can increase the relay, the transmission distance can be more than doubled.
13. Light life: 100,000 hours.
14. Continuous use time requirements: alarm detection ring of 100 hours, alarm controller s 100 hours, main box alarm s 100 hours.
15. Equipment alarm volume: main alarm box body s 110 decibels.
16. Alarm detection ring: rain-proof, anti-corrosion, carrying impact crushing, 2 meters high fall without damage.
17. Working environment: all-weather can be in the environment of -20 degrees C to 80 degrees C long-term continuous work, no impact.
18, far-sighted warning light: ultra-high brightness 4LED (23000-26000mcd);
