Description

Technical Field

[0001] The utility model belongs to the technical field of alarm equipment, and in particular relates to a vehicle anti-intrusion alarm device. Background Art

[0002] The on-site road operation vehicle intrusion prevention equipment currently on the market mainly restricts the vehicle's driving route and prevents it from mistakenly entering the on-site work area by setting up physical obstacles (such as anti-collision cones, anti-collision barrels, warning lines, etc.), signal lights and alarm devices. In addition, some advanced equipment can also use radar detection, infrared detection and other technologies to achieve dynamic monitoring of vehicles and real-time alarms.

[0003] However, the above method has the following disadvantages: when the venue is large and long, relying on physical obstacles, signal lights, and alarm devices, it is easy to fail to quickly and timely obtain alarm information after the early warning is triggered, resulting in off-site personnel being unable to obtain alarm information and unable to establish effective contact with back-end support personnel; and radar detection, infrared detection and other technologies are relatively complex, and the cost of equipment is also higher, requiring professional personnel to operate and maintain, which increases the difficulty of work, so a new type of alarm device to prevent vehicle intrusion is needed, and the utility model solves this technical problem.
