[0034] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0035] Figure 1 A wireless alarm for preventing scratches on power lines according to an embodiment of the present disclosure is shown. Figure 1 As shown, it includes a sensing device 1 and an alarm device 2. The sensing device 1 is set in an area where the device is close to or far away from the power line during operation, and the alarm device 2 is set at the control end of the device;

[0036] The sensing device 1 is connected to the alarm device 2 via electrical signals, and the sensing device 1 includes a near-electricity alarm 3 .

[0037] It should be noted that in the embodiments of the present disclosure, the equipment includes but is not limited to cranes, loaders, excavators and dump trucks, and can also be applied to equipment in other application scenarios where the equipment may be close to power lines.

[0038] In some embodiments, there may be multiple sensing devices 1 and at least one alarm device 2. The number of alarm devices 2 may depend on the number of operators, and the number of sensing devices 1 depends on the number of areas where interference with power lines may occur. At least one sensing device 1 is provided in an area where interference with power lines may occur.

[0039] Preferably, in the embodiment of the present disclosure, the sensing device 1 and the alarm device 2 are connected wirelessly;

[0040] Specifically, if Figure 2 and Figure 3 As shown, the sensing device 1 is provided with a wireless transmitter 4, and the alarm device 2 is provided with a signal receiving component for receiving the signal sent by the wireless transmitter 4; further, the output end of the wireless transmitter 4 is provided with a first antenna 40, and the signal receiving component includes a wireless relay 41 and a second antenna 42 arranged at the signal input end of the wireless relay 41.

[0041] It should be noted that, in some embodiments, the antenna signals of the sensing device 1 and the alarm device 2 can realize the transmission of electrical signals through impedance matching or frequency matching. Specifically, the impedance matching refers to the impedance matching between the tuning circuit and the antenna, so that their impedance values are equal or similar to achieve maximum power transmission. Impedance mismatch will cause the signal transmission power to decrease and the transmission distance to be shortened, and may also damage the antenna component; for the receiving antenna, impedance mismatch will lead to a decrease in receiving sensitivity, introduce noise interference, and affect the quality of the received signal.

[0042] The frequency matching mentioned above refers to the frequency matching between the tuning circuit and the antenna, so that it has the best transmission performance at a specific frequency. The frequency of the antenna should match the frequency of the wireless module. For example, a 433MHz wireless module needs to match a 433MHz antenna.

[0043] Preferably, in the embodiment of the present disclosure, the sensing device 1 further includes an audio relay 5, the alarm device 2 includes an output terminal connected to the near-electricity alarm 3, and the audio relay 5 converts the signal of the near-electricity alarm 3 into an audio control signal;

[0044] It should be noted that the audio relay 5 can control the audio system to emit a specific alarm sound when the near-electric alarm 3 triggers the alarm. At the same time, the control signal can be amplified by the audio relay 5, so that the weak near-electric alarm signal 3 can drive the audio system to produce a sufficiently loud alarm sound; finally, the audio relay 5 can be used as a logic judgment element to judge whether it is necessary to trigger an audio alarm based on the output signal of the near-electric alarm 3. When the near-electric alarm 3 detects a charged area and issues an alarm signal, the audio relay 5 receives the signal and triggers the audio system to emit an alarm sound. By switching the contacts of the audio relay 5, the on and off of the audio signal can be controlled to turn the alarm sound on and off.

[0045] Preferably, in the embodiment of the present disclosure, the alarm device 2 includes an audible alarm 50 , and further, the alarm device 2 includes a warning light 6 ;

[0046] It should be noted that in some disclosed embodiments, the warning methods include sound warning and light warning. The sound warning is achieved through an audible alarm, which usually includes a sound sensor, a signal processing circuit, and a sound-emitting device. When an emergency is detected, the sound sensor converts the signal into an electrical signal. After processing by the signal processing circuit, the sound-emitting device emits a high-decibel alarm sound; the warning light 6 is used for light warning, and emits colored light when a warning is required to achieve light reservation.

[0047] In other embodiments, in order to improve the applicability of the sensing device 1 and the alarm device 2, the sensing device 1 and the alarm device 2 are both provided with a battery 7, which provides power to each component; further, the sensing device 1 and the alarm device 2 are both provided with a manual switch 8, which can be used to turn the sensing device 1 and the alarm device 2 on and off.

[0048] In other embodiments, the sensing device 1 is detachably connected to the control end of the device; it should be noted that the detachable connection can be achieved through certain connectors or by adsorption. Specifically, the connector can be a snap-on connector or a connector connected by bolts, and the adsorption method can be through magnetic attraction or bonding.

[0049] In some embodiments, the proximity alarm 3 described in this application uses the control circuit of the proximity alarm function of the JW0828 chip. In a non-contact situation, it generates an audible alarm when an electric field is sensed. The 4kHz audio signal of the audible alarm is connected to the audio relay 5. The audio relay 5 is a switch module. The switch module triggers the switch value to control the wireless remote control to output the electrical signal;

[0050] The near-electric alarm 3 adopts the mature Shianda anti-electric shock warning device currently on the market. The near-electric alarm 3 can send out an alarm signal near the live lines of 220V to 220kV. The alarm has 5 gears for adjustment, which can be used as the gears for adjusting the live distance and sensitivity on site. The alarm range is 0.8 meters to 5 meters, which meets the safety distance requirements on site. The near-electric alarm 3 adopts the control circuit of the JW0828 near-electric alarm function. It sends out a 4kHz audio signal when it detects the presence of a live line within the range. When an audio signal is detected, the audio relay 5 is started, and the audio relay 5 disconnection delay range is 0.1 seconds to 99.9 seconds.

[0051] The sensing device 1 and the alarm device 2 are connected by electrical signals through a wireless transmission module. The wireless transmission module is implemented by a common wireless remote control on the market. The remote control distance is 100 meters in an open space without interference. The actual use depends on the degree of interference, obstacles and loads in different environments, and fully meets the on-site wireless transmission distance requirements.

[0052] Specifically, in some other embodiments, the sensing device 1 is installed in an ABS plastic waterproof box with ears, with dimensions of 115mm long, 90mm wide, and 68mm high. Round, perforated NdFeB magnets are installed at the four corners of the bottom. The signal detection box is attached to the top of the crane boom or the upper part of the bucket, allowing for easy removal after construction is completed. The warning light 6 of the alarm device 2 is a QY-01J rechargeable light alarm light with a built-in 12V rechargeable battery. The wireless remote control receiving module is installed inside the alarm device 2, which has a built-in magnetic adsorption function and can be attached to the machine cab. It should be noted that the wireless remote control receiving module includes a second antenna 40 and a wireless relay 41.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
