Description

Technical Field

[0001] This utility model relates to a high-voltage safety distance early warning system. Background Technology

[0002] Traditional high-voltage safety distance early warning systems rely on physical contact detection and cannot perceive dynamically changing electric field environments in real time. Currently, outdoor construction machinery (such as cranes, pump trucks, and excavators) operating near high-voltage transmission lines face the risk of electric shock due to insufficient safety distance. Existing electronic early warning equipment suffers from poor voltage level adaptability, struggling to be compatible with a wide voltage range from 220V to 220KV; low standardization of data interfaces makes data exchange with the CAN bus systems of construction machinery difficult; and high false alarm rates and decreased detection accuracy occur under adverse weather conditions. Utility Model Content

[0003] The main objective of this invention is to provide a high-voltage safety distance early warning system, which aims to solve the aforementioned technical problems.

[0004] To achieve the above objectives, this utility model proposes a high-voltage safety distance early warning system, which includes a signal transmitter and a signal receiver. The signal transmitter and the signal receiver are electrically connected so that when the signal transmitter detects the distance between the working vehicle and the high-voltage power line, it transmits the detected signal to the signal receiver. The signal receiver is electrically connected to a CAN bus to transmit the detected signal to the CAN bus.

[0005] In one embodiment, the signal transmitter includes a first housing having a first cavity and a first control board disposed within the first cavity. The first housing is provided with an inductive antenna and a first communication antenna electrically connected to the first control board. The first communication antenna is signal connected to the signal receiver.

[0006] In one embodiment, the first outer shell includes a first lower cover, a first middle cover, and a first upper cover, with the first lower cover and the first upper cover respectively disposed on both sides of the first middle cover to form the first cavity.

[0007] In one embodiment, the signal transmitter further includes a first mounting plate disposed on the first lower cover, the first mounting plate having a plurality of first mounting holes.

[0008] In one embodiment, the signal receiver includes a second housing having a second cavity and a second control board disposed within the second cavity. The second housing is provided with a second communication antenna electrically connected to the second control board, and the second communication antenna is connected to the CAN bus signal.

[0009] In one embodiment, the second outer shell includes a second lower cover, a second middle cover, and a second upper cover, with the second lower cover and the second upper cover disposed on both sides of the second middle cover to form the second cavity.

[0010] In one embodiment, the second control panel is provided with a plurality of control buttons, and the second upper cover is provided with through holes for exposing the control buttons.

[0011] In one embodiment, the second upper cover is provided with a panel film, the panel film having an indicator label corresponding to the control button.

[0012] In one embodiment, the signal receiver further includes a second mounting plate disposed on the second lower cover, the second mounting plate having a plurality of second mounting holes.

[0013] In one embodiment, a buzzer electrically connected to the second control board is provided in the second cavity.

[0014] In this invention, the high-voltage safety distance early warning system includes a signal transmitter and a signal receiver. The signal transmitter and receiver are electrically connected, so that when the signal transmitter detects the distance between the working vehicle and the high-voltage power line, it transmits the detected signal to the signal receiver. The signal receiver is electrically connected to a CAN bus to transmit the detected signal to the CAN bus. Therefore, in this invention, when the signal transmitter is installed on the working vehicle, it can detect the distance to the high-voltage power line and transmit the signal to the signal receiver, which then transmits it to the CAN bus. An alarm is triggered when the distance is less than a threshold, avoiding the risks associated with physical contact detection during severe weather. Attached Figure Description

The second outer shell 21 includes a second lower cover 211, a second middle cover 212, and a second upper cover 213. The second lower cover 211 and the second upper cover 213 are respectively disposed on both sides of the second middle cover 212 to form the second cavity 214. The first lower cover 111, the first middle cover 112, and the first upper cover 113 can be connected by fasteners. Meanwhile, to improve waterproof performance, a sealing ring can be provided at the connection point of the first lower cover 111, the first middle cover 112, and the first upper cover 113. Similarly, the connection method between the second outer shell 21 and the first outer shell 11 can adopt the same structure, which will not be described again.
