Description

The present invention relates to an emergency remote notification system for warning a worker working in a vehicle intrusion prohibited area provided on a road.

Conventionally, when performing accident handling and maintenance work on a road, it is almost always performed by regulating the lane in which the vehicle is passing. As the means, a pylon, a guidance sign, etc. are installed in the traveling direction of the vehicle, and an intrusion prohibited area is provided to block the passage of the vehicle. Furthermore, during the work, in order to prevent the vehicle from entering the vehicle intrusion prohibited area by mistake, the worker waves a flag to alert the passing vehicle. However, due to a drowsy driving, vehicle operation mistakes, and the like, there are always accidents in which an operator is involved in an accident due to a vehicle entering the vehicle entry prohibition area by overturning a pylon or a guidance sign.

In view of such a situation, as seen in Patent Document 1 shown in 4-A of FIG. 4 and Patent Document 2 shown in 4-B, a vehicle intrusion into the intrusion prohibited area is detected and an alarm is issued. A system has been devised that prompts workers to call attention. The former uses a switch, a pressure sensor, an ultrasonic sensor, etc. as a trigger for the weight of the vehicle as a method for detecting entry into the vehicle entry prohibition area, and wirelessly sends the detection result to an alarm device to issue an alarm. To alert the workers. In the latter case, a rod-like object with a built-in vibration detection sensor is installed in such a manner that a commercially available rubber cone is connected to a part that is thought to enter the vehicle intrusion prohibited area. An alarm is issued from an alarm device in which the detection result is wired.

However, since the detection result by "the vehicle has contacted the sensor" serves as a trigger in any of these, alerting by an alarm is always performed after that. In other words, in consideration of the notification for avoiding the danger of competing for a few seconds of commas, it is necessary to use a notification means that enables notification at the stage before the vehicle has entered. In addition, even if a warning or light alert is actually issued, if the operator is not aware of the alarm, the meaning of the emergency remote notification system to avoid danger is lost. is there.
