JP3013157U - Emergency vehicle approach wireless alarm device - Google Patents

Abstract

(57) [Summary] [Purpose] The sound of the warning siren emitted by an emergency vehicle is often not heard by the driver of the vehicle in front of it or the vehicle near the intersection, which prevents the emergency vehicle from running quickly. The purpose is to solve this and eliminate social anxiety. The present invention comprises an alarm transmitter mounted on an emergency vehicle, an alarm receiver equipped on a general vehicle, and an in-vehicle alarm device, that is, an alarm buzzer and an alarm light, which are linked to the alarm transmitter. The transmitted radio wave is weak at a specific frequency that does not affect others and the direction is limited only to the front. When the alarm receiver receives a radio wave of a specific frequency, it amplifies this, turns on the switch of the in-vehicle alarm device, connects the alarm buzzer and the alarm light to the battery, and alerts the driver. As a result, an emergency vehicle can be driven quickly and social unrest can be resolved.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for revising that a siren or a red or yellow rotating light of an emergency vehicle is hard to be noticed by a driver who is driving the vehicle.

[0002]

[Prior art]

 Emergency vehicles use red or yellow lights to rotate or blink and warning sirens as approach warning devices, and are driving while giving warnings to vehicles traveling in front or in other lanes. For people, there is a lot of noise in the surroundings, and most of the outside noise is blocked when the windows are closed, so in any case, the approach of an emergency vehicle may not be noticed. In this state, it is impossible for an emergency vehicle to drive quickly, and it is not possible to reduce the number of emergency vehicle accidents at intersections. In addition, the delay of an emergency vehicle involves a serious problem and requires an urgent solution.

[0003]

[Problems to be solved by the device]

 An object of the present invention is to provide a device for ensuring that the alarm of an emergency vehicle reaches the drivers of vehicles in front of and around the vehicle in order to ensure that the emergency vehicle travels smoothly and travels smoothly as described above. To do.

[0004]

[Means for Solving the Problems]

 The woodworking device consists of the following three combinations. They are an alarm radio transmitter mounted on an emergency vehicle, an alarm receiver equipped on a general vehicle, a warning light and a warning buzzer that are turned on to warn the driver.

[0005]

[Action]

 Warning radio wave transmitter Wire in an emergency vehicle to link with the warning siren and transmit only the specific frequency that has less effect on others. The transmission direction is limited to the front, and the transmission distance is limited to a short distance, so the transmission power is limited to an extremely small amount. Dedicated receiver for alarms Dedicated to a specific frequency so that it will not be activated by radio waves other than emergency vehicle alarms, and will be ready to receive signals only when the engine switch is activated. Alarm device When an alarm signal flows to the alarm receiver, the current is amplified and the alarm light installed in front of the driver is turned on and the alarm buzzer sounds. By the above operation, the general vehicle opens the passage to the emergency vehicle, and the emergency vehicle can smoothly and promptly reach the destination and accomplish the mission.

【Example】

 FIG. 1 is a circuit diagram of an alarm radio transmitter mounted on an emergency vehicle. When the switch 1 is turned on, the siren 3 sounds by the power of the battery 2 and at the same time the transmitter 4 is activated, and the antenna 5 emits a weak radio wave of a specific frequency forward. The back of the antenna 5 is covered with a shield 6. FIG. 2 shows a receiver installed in a general vehicle and an alarm device interlocked with the receiver. Switch 11 should be turned on when passing through a place with a lot of vehicles where the siren of an emergency vehicle cannot be heard. When the switch 11 is turned on, the voltage of the battery 12 is applied to the receiver 14. If there is a specific radio wave transmitted from an emergency vehicle, it will be amplified from the antenna 15 to the receiver 14 and the switch 19 of the alarm device 16 will be automatically turned on to sound the warning buzzer 17 in the driver's seat and the warning light 18 Illuminates to warn of an approaching emergency car.

[0007]

[Effect of device]

 In recent years, the number of vehicles on the streets has increased and it has become difficult for emergency vehicles to pass through.In addition, the noise on the roads has become so severe that it is difficult for drivers of ordinary vehicles to hear the approach warning of emergency vehicles. Obstacles to frequent traffic became common. This is a serious problem for society and must be resolved immediately. The present invention solves this problem and is desired to be widely spread.
