[0024] Figure 1 A schematic diagram of the structure of a radar device provided in an embodiment of the present application is shown. For the sake of convenience, only the parts related to the present embodiment are shown, which are described in detail as follows:

[0025] The radar device 10 includes a power module 100 , a main control module 200 and an external module 300 .

[0026] The power module 100 is used to generate and output an operating voltage based on an input voltage. The main control module 200 is connected to the power module 100. The external module 300 is connected to the main control module 200 and / or the power module 100, the external module 300 is used to connect to an external device, and the main control module 200 is used to control the external module 300 to output a supply voltage.

[0027] The external module 300 can transmit a power supply voltage to an external device to drive the external device, thereby avoiding setting up an additional power supply line for the external device and reducing the complexity, design difficulty and construction cost of the overall circuit.

[0028] In one embodiment, if Figure 2 As shown, the power module 100 includes a DC voltage regulator unit 110 and an energy storage unit 120. The DC voltage regulator unit 110 is used to connect to an external power source, and the energy storage unit 120 is connected between the DC voltage regulator unit 110 and the main control module 200. The DC voltage regulator unit 110 is used to perform voltage conversion based on the input DC power to generate and output DC power of a target voltage, and the energy storage unit 120 is used to store the electric energy output by the DC voltage regulator unit 110 and output a working voltage, which can drive the main control module 200 or other modules to work. Among them, the energy storage unit 120 can be a battery pack.

[0029] For example, the DC voltage regulator unit 110 can convert 24V DC power into 5V, 12V, and 24V DC power. The power output by the DC voltage regulator unit 110 can be directly provided to other power-consuming modules including the main control module 200. The energy storage unit 120 can be charged based on the power output by the DC voltage regulator unit 110, and can also output a working voltage. The main control module 200 can select a suitable working voltage according to demand.

[0030] Exemplarily, in some embodiments, the DC voltage regulation unit 110 includes a DC / DC converter, and the energy storage unit 120 includes a battery pack.

[0031] In some embodiments, Figure 2 As shown, the power module 100 further includes a power output interface 130 , which is connected to the energy storage unit 120 . The power output interface 130 is used to connect to an external device to directly output electrical energy to the external device.

[0032] In one embodiment, if Figure 3 , Figure 4 As shown, the radar device includes a housing 20 , the external module 300 includes a POE (Power Over Ethernet) transmission chip and a POE output interface 320 , and the power supply voltage includes a POE output voltage.

[0033] The first end of the POE transmission chip 310 is connected to the main control module 200, and the second end of the POE transmission chip 310 is connected to the POE output interface 320. The main control module 200 is used to control the POE transmission chip 310 to output the POE output voltage through the POE output interface 320 based on the working voltage.

[0034] It can be understood that the POE output interface 320 can be connected to a camera to provide a POE output voltage to the camera, and the POE output voltage can drive the camera to work.

[0035] In one embodiment, if Figure 3 , Figure 4As shown, the external module 300 includes a network cable transmission chip 330 and a network cable output interface 340, and the power supply voltage includes a network cable output voltage.

[0036] The first end of the network cable transmission chip 330 is connected to the main control module 200, and the second end of the network cable transmission chip 330 is connected to the network cable output interface 340. The main control module 200 is used to control the network cable transmission chip 330 to output the network cable output voltage through the network cable output interface 340 based on the working voltage.

[0037] It is understandable that the network cable output interface 340 can be connected to a corresponding external device via a network cable.

[0038] Exemplarily, in some embodiments, the specific model of the network cable output interface 340 is an RJ45 interface.

[0039] In one embodiment, if Figure 3 , Figure 4 As shown, the external module 300 includes a sensor transmission chip 350 and a sensor output interface 360, and the power supply voltage includes a sensor output voltage.

[0040] The first end of the sensor transmission chip 350 is connected to the main control module 200, and the second end of the sensor transmission chip 350 is connected to the sensor output interface 360. The main control module 200 is used to control the sensor transmission chip 350 to output the sensor output voltage through the sensor output interface 360 ​​based on the working voltage.

[0041] It is understandable that the sensor output interface 360 ​​can be connected to a corresponding sensor. For example, the sensor can be an additional meteorological sensor or other monitoring sensor.

[0042] In some embodiments, the sensor output interface 360 ​​may be a RS232 interface or a RS485 interface. The specific interface used by the sensor output interface 360 ​​may be determined according to the sensor to be connected.

[0043] In some embodiments, the POE output interface 320 , the network cable output interface 340 , and the sensor output interface 360 ​​are all cable direct plug-in ports or multi-core aviation plug-in interfaces.

[0044] In some embodiments, the specific structure of the multi-core aviation plug interface includes a threaded opening, a waterproof nylon connector and a multi-core aviation plug, wherein the waterproof nylon connector is disposed in the threaded opening, and the multi-core aviation plug is embedded in the waterproof nylon connector. The threaded opening can ensure that the connector of the cable can be tightly mounted on the multi-core aviation plug. By configuring the functions of each core in the multi-core aviation plug, the multi-core aviation plug can communicate with multiple sensors and also supply power to each sensor.

[0045] In one embodiment, if Figure 3, Figure 4 As shown, the radar device 10 further includes a communication interface 400 .

[0046] The communication interface 400 is connected to the main control module 200;

[0047] The communication interface 400 is used to connect to an external communication device, and the communication interface 400 is used to exchange data with the external communication device.

[0048] It is understandable that the main control module 200 can perform logic operations, data processing, and control the communication unit. The number and model of the communication interface 400 can be configured according to the actual needs of the external communication device.

[0049] The main control module 200 may be a microcontroller such as a chip or a digital circuit. The external communication device may be a sensor, a remote controller, a mobile phone, a computer, a server, or other devices.

[0050] In one embodiment, the communication interface 400 includes a fiber optic communication chip 410 and a fiber optic interface 420;

[0051] A first end of the optical fiber communication chip 410 is connected to the main control module 200 , and a second end of the optical fiber communication chip 410 is connected to the optical fiber interface 420 .

[0052] It is understandable that the external communication device may be connected to a suitable communication interface 400 according to the type and model of the external communication device.

[0053] In some embodiments, the POE transmission chip 310, the network cable transmission chip 330, the sensor transmission chip 350 and the optical fiber communication chip 410 can be arranged on an independent PCB board and arranged near the corresponding interface. It is understandable that since each interface needs to perform the operation of plugging and unplugging cables, arranging the POE transmission chip 310, the network cable transmission chip 330, the sensor transmission chip 350 and the optical fiber communication chip 410 on an independent PCB board can reduce the structural stress caused by plugging and unplugging cables on other internal PCB boards.

[0054] In one embodiment, if Figure 3 , Figure 4 As shown, the radar device 10 further includes a radio frequency antenna 500 and a radio frequency unit 600. The radio frequency unit 600 is connected to the radio frequency antenna 500 and the main control module 200 respectively.

[0055] The main control module 200 can transmit and receive RF signals by controlling the RF unit 600 and the RF antenna 500 to perform speed measurement, distance measurement, etc., and transmit the acquired data to the main control module 200. The main control module 200 can process the data and then transmit the processed data to the server through the communication unit.

[0056] The number and type of the RF antenna 500 can be set according to actual conditions. The RF unit 600 and the main control module 200 can be connected via a 4-core network cable.

[0057] It is understandable that when the RF antenna 500 is an external antenna, the RF unit 600 and the RF antenna 500 can be connected through the corresponding RF interface 700. When the RF antenna 500 is a fixed antenna of the radar device, the RF unit 600 and the RF antenna 500 can be directly connected through a circuit.

[0058] In one embodiment, the RF antenna 500 includes multiple millimeter-wave radar antennas, the RF unit 600 includes multiple millimeter-wave radar control chips, and the millimeter-wave radar antennas correspond to the millimeter-wave radar control chips one by one and are interconnected.

[0059] It is understandable that the millimeter wave radar antenna and the millimeter wave radar control chip can be connected through the corresponding RF driver chip, and the RF driver chip is used to send and receive RF signals. Multiple millimeter wave radar antennas and multiple millimeter wave radar control chips can detect different detection areas respectively to achieve the effect of mutual blindness.

[0060] Exemplarily, in one embodiment, the radar device 10 includes two millimeter-wave radar antennas and two millimeter-wave radar antennas.

[0061] In some embodiments, the two millimeter wave radar antennas can be respectively arranged on different PCB boards, the RF driver chip can be arranged on another independent PCB board, and the main control module 200 can be arranged on an independent PCB board. The PCB boards are installed in parallel and at intervals.

[0062] In one embodiment, if Figure 3 , Figure 4 As shown, the RF antenna 500 includes a cascade communication antenna 510, and the RF unit 600 includes a cascade communication chip. The first end of the cascade communication chip is connected to the main control module 200, and the second end of the cascade communication chip is connected to the cascade communication antenna 510. Wireless communication can be carried out with other radars through the cascade communication chip and the cascade communication antenna 510 to realize the cascading of multiple radars.

[0063] Specifically, in some embodiments, the cascade communication antenna 510 is a 433 antenna.

[0064] In one embodiment, if Figure 3 , Figure 4 As shown, the radio frequency antenna 500 includes a positioning antenna 520 , and the radio frequency unit 600 includes a positioning chip. The positioning antenna 520 and the positioning chip are used to obtain the position information of the radar device 10 .

[0065] The position of the radar device 10 can be quickly determined by the positioning antenna 520 and the positioning chip, so that the radar device 10 can be quickly deployed. The radar device 10 can adjust some of its own parameters according to its own position information.

[0066] Among them, the positioning antenna 520 and the positioning chip can be specifically used for GPS positioning and / or Beidou positioning.

[0067] Exemplarily, in one embodiment, the positioning antenna 520 is a Beidou antenna, and the positioning chip is a Beidou chip.
