[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. Using the wireless magnetic sensing device and sound and light alarm control module pre-buried in the road, when a vehicle passes through a blind turning area, the vehicle is detected and automatically gives a sound and light alarm to remind oncoming vehicles or people that a vehicle is passing by, thus preventing the risk of collision between vehicles and people, or between vehicles. When no vehicle passes through the road section, the device does not give a sound and light alarm.

[0011] 2. The device is equipped with a magnetic sensitive sensor, which outputs different flux signals based on the magnetoresistance effect when a vehicle passes by, and sensitively captures the information of whether the vehicle passes through the blind spot.

[0019] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application; as used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or their combinations.

[0021] A magnetically sensitive sound and light alarm device for vehicles in blind turning areas, reference Figure 1-3 , including a solar module 5, a power control module 2, an acoustic and light alarm control module 3, an acoustic and light alarm module 1, and a wireless magnetic sensitive sensor 4 pre-buried on the road; the wireless magnetic sensitive sensor 4 contains a transmitter, and the acoustic and light alarm module 1 contains a receiver; the transmitter and the receiver perform channel matching; the acoustic and light alarm module 1 includes an LED lamp bead and a voice broadcast module; the acoustic and light alarm control module 2 is connected to the acoustic and light alarm module 1. When a vehicle passes by the wireless magnetic sensitive sensor 4, the wireless magnetic sensitive sensor 4 automatically activates the pulse working mode, and when the vehicle does not pass by, the device automatically switches to a dormant standby state to achieve low-power communication. The wireless magnetic sensitive sensor 4 has a detection sensing range of a 1.2m sphere centered on the wireless magnetic sensitive sensor 4, an operating temperature of -20℃ to 70℃, and is considered to be pre-buried on the road surface, and the dust and water resistance level is IP68. The solar module 5 and the high-energy lithium battery complement each other to provide power to achieve wireless power supply.

[0022] When a vehicle passes by the wireless magnetic-sensitive sensing device 4 , the wireless magnetic-sensitive sensing device 4 automatically activates the pulse working mode.

[0023] The device uses radio frequency code wireless signal communication. Before use, the wireless magnetic sensitive sensing device 4 (containing a transmitter) is first matched with the sound and light alarm control module 3 (containing a receiver) for channel matching. After the match is successful, when the vehicle passes the wireless magnetic sensitive sensing device 4, a signal is sent. When the sound and light alarm control module 3 receives the corresponding signal, the sound and light alarm module 1 is triggered to play the corresponding voice and emit a flash. The flash is a red and blue LED lamp bead. The sound and light alarm module 1 is a switch signal alarm that supports voice replacement and adjustable volume. The volume range is 60-130dB. The device is set outdoors, with a waterproof and dustproof level of IP54, an operating temperature of -20℃ to 70℃, and an ABS plastic shell. Considering the warning effect, the alarm is wall-mounted. The power control module 2 converts 220V AC into 24V DC that can be used by the device.

[0024] The working principle of the circuit of the embodiment of the utility model is as follows: when a vehicle passes over the wireless magnetic sensitive sensing device 4 embedded in the blind spot of a turn, the ground sensing transmitter of the wireless magnetic sensitive sensing device 4 transmits a signal, and the receiver of the wireless magnetic sensitive sensing device 4 receives the signal, thereby triggering the sound and light alarm module 1 to emit a sound and light alarm. The device power control module converts 220V AC power into 24V DC power that can be used by the device.
