I. Systematic overview
This equipment can effectively prevent the occurrence of secondary accidents when dealing with the traffic accident scene, and is a barrier to ensure the safety of police personnel on the scene. The anti-intrusion alarm equipment independently developed by Shenyang De'an Intelligent Technology Co., Ltd. is extremely simple to use. When using the anti-intrusion alarm equipment, only the alarm detection circle is removed from the main equipment and placed on the front cone of the accident scene. When a vehicle intrudes into the accident scene, the back-end main equipment and the accompanying alarm receives the alarm signal, sends out sound, light and vibration to alarm, prompts the police officers on the scene to avoid accidents in time.
2. Equipment Characteristics and Advantages
1. Easy to carry, easy to use, and only 1-3 minutes to arrange to prevent intrusion into the site.
2. It works safely and reliably. The alarm delay is only 0.02 seconds, which is equivalent to synchronous triggering.
3. The communication distance is long, the straight line distance is 1750 meters, and the relay can be used to increase the communication distance.
4. The ultra-low power design of alarm detection circle, which can work continuously for more than 140 hours at a time full of electricity, is enough to meet the needs of long-term on-site work.
5. Wireless transmission adopts 433MHz to 470MHz industrial frequency band, which has strong anti-interference ability.
6. The main equipment is not only the carrier of alarm detection circle, but also its charger. This design is simple in maintenance, flexible in use, compact in structure, and really realizes simple operation.
III. Equipment Function
1. By the alarm detection ring, the preset cone (provided by the user), the main box high-power alarm and hand-held wireless alarm controller.
2. Early warning detection aperture can be detected by vibration, displacement and gravity acceleration, through intelligent judgment and wireless digital transmission technology.
3. It can actively prevent sound and light warning in advance, warn people or motor vehicles to break in illegally, and remind drivers to take prompt measures to brake vehicles so as to avoid accidents.
4. The alarm signal can be sent by wireless to trigger the sound and light hand-held wireless alarm controller that each policeman wears on the scene, prompting the field staff to quickly evacuate the scene, so as to avoid injuries and secondary accidents caused by intruding into motor vehicles.
5. Can trigger the field wireless high-power alarm, prompt other people who do not wear the sound and light hand-held wireless alarm controller to avoid intruding into the vehicle and quickly evacuate to the safety zone.
6. Use mode: outdoor use, portable alarm, wireless networking, wireless transmission reception and control, high-power alarm.
7. Working mode: The alarm detection trap is placed on the preset cone barrel to work automatically on the road without supervision.
8. Early warning mode: collision and displacement passive alarm, alarm sound control output.
9. Equipment Material Requirements: PC polycarbonate high-strength engineering plastics are used in the alarm detection ring, and ABS high-strength plastics are used in the handheld wireless alarm controller, which is rugged and durable.
10. Networking scope: 5-30 wireless networking.
11. Wireless alarm transmission receiving distance: between warning rings (> 350 meters); alarm (> 350 meters);
12. The alarm detection ring has the function of signal relay, and the transmission distance can be greatly increased.
13. Lighting life: 100,000 hours.
14. Continuous use time requirements: alarm detection circle (> 140 hours), alarm controller (> 140 hours), main box alarm (> 140 hours).
15. Equipment alarm volume: the main alarm box is more than 110 decibels.
16. Alarm detection circle: rainproof, anti-corrosion, impact rolling (3 tons without damage), 10 meters high falling without damage
17. Working environment: It can work continuously for a long period of time in the environment of - 40 ~80 ~C all day without any influence.
18. Long-range warning lamp: Ultra-high brightness 4LED (23000-26000mcd); 60 flickers per minute, visible distance 500m, lamp body 360-deg; self-luminescence.
