Portable sound and light barricade warner

Abstract

The invention discloses a portable sound and light barricade warner which comprises a main box body. The main box body is formed by digital control welding compression moulding and provided with a main power switch, an LED battery electric quantity display key and a fuse holder. A DC 12 V lithium battery, a power converter, a master control circuit board, a display screen driving circuit board, a sound image synchronization circuit board, a sound processor, a power amplifier, a wireless voice receiver, a remote control receiver and a loudspeaker are installed in the main box body. An LED display screen is installed on the front of the main box body, a portable pull rod and a cooling fan are installed on the back of the main box body, a portable rubber roller is installed at the bottom of the main box body, and a flashing light is connected with the main box body through a telescopic pull rod. The warner is powered by the DC 12 V lithium battery, and each warning function, such as sound warning, the flashing light, graphics context display, graphics context modification by a WIFI mobile device and walkie talkie timely interruption real-time scheduling, is subjected to coordinated control by a main control circuit.

[0002] When carrying out "accident handling and emergency rescue", time is often tight, tasks are heavy, and risks coexist; traditional "traffic police accident handling", "highway emergency rescue", "road maintenance and troubleshooting" and other work area warnings are Putting warning signs, cones, tripods and other static warning objects, the warning effect is not good; and when there is bad weather such as rain, ice and snow, the warning effect is even worse; in practice, the above warning objects are easy to weather and age. It often affects its warning effect; and for a long time, how to ensure safe entry to the operation (construction) site at the first time, and place warning signs and cones to delineate the operation (construction) area, and at the same time ensure the safety of operation personnel , to reduce the occurrence of secondary disasters, has been plagued by the majority of traffic police and expressway operating companies

So far, secondary disasters have emerged endlessly due to the backwardness of warning facilities, failure to place more effective three-dimensional warning devices immediately after arriving at the scene, or directly turning around to place cones to delineate the operation (construction) area. It can be said that almost every day There are similar secondary disasters
