[0022] To enable those skilled in the art to better understand the technical solution of this application, the following description is provided in conjunction with the appendix.

[0023] The figures and preferred embodiments further illustrate the present invention in detail.

[0024] like Figure 1 , Figure 2 and Figure 10 As shown, this application proposes an image acquisition device suitable for urban drainage environments: it includes an image acquisition module 1, a supplementary light 2, a body 3, and a bracket 4. The image acquisition module 1 is fixedly installed on one side inside the body 3, and several supplementary lights 2 are arranged in a circular array around the image acquisition module 1. A sealing plate 5 is fixedly installed at the end of the body 3, and a lens 6 capable of covering the projection range of the supplementary lights 2 and the image acquisition module 1 is installed in the middle of the sealing plate 5. The bracket 4 is hinged to the side end of the body 3. A main control unit connected to the image acquisition module 1, and a power control circuit and a communication circuit connected to the main control unit are installed inside the body 3.

[0025] The sealing plate 5 is connected to the end flange of the body 3, and the lens 6 is snapped into the middle area of ​​the sealing plate 5.

[0026] The bracket 4 has a base 4-1 at its bottom, and the base 4-1 has a positioning hole 4-2.

[0027] The power control circuit includes a buck converter circuit, a boost converter circuit, and a power acquisition circuit, all connected to the battery. The buck converter circuit is used to generate a power supply voltage suitable for use by circuit board components. The boost converter circuit is used to generate a power supply voltage suitable for use by external sensors. The power acquisition circuit is used to collect the remaining battery power in real time.

[0028] like Figure 3 As shown, the main power source of the device in this application is a high-capacity lithium battery. The voltage of the lithium battery is reduced to a power supply voltage suitable for the circuit board components through a step-down conversion circuit. Specifically, the lithium battery is connected to the P1 terminal, and the voltage is reduced to 3.8V through the DC-DC chip U2. At the same time, C7 is set as a 20F supercapacitor. Its function is to cut off the voltage converted by the step-down conversion circuit when the device is in low power operation, so that the overall power supply of the device is turned off.

[0029] like Figure 4 As shown, the power input of the boost converter circuit comes from the lithium battery. After boosting, it supplies power to the external sensor through P2. The external power supply is controlled by PWRVOUT. CTLUP is used to control the working state of the boost chip U6 to achieve different voltage outputs and generate voltages that are compatible with more sensors.

[0030] like Figure 5 As shown, the power acquisition circuit includes an operational amplifier attenuation circuit to achieve accurate power measurement.

[0031] The image acquisition module 1 is a black-light level CMOS photosensitive module. The image acquisition module circuit is as follows: Figure 9 As shown, TXD4 and RXD4 are data communication pins, RST3 is the module reset pin, and EN0 is the module low-power control pin.

[0032] The communication circuit includes a sensor communication circuit, a LoRa communication circuit, and a 4G communication circuit arranged in parallel.

[0033] The sensor communication circuit interacts with external sensors, the LoRa communication circuit is used to build a Mesh network among multiple image acquisition devices, and the 4G communication circuit directly transmits data to the cloud server through the cellular network.

[0034] The specific settings of the sensor communication circuit are as follows: Figure 6 As shown, the communication between the device and the external sensor uses RS485. TXD1 and RXD1 are data communication pins, RTS is the RS485 transmit / receive control pin, and P2 is connected to the external sensor communication interface.

[0035] The specific settings of the LoRa communication circuit are as follows: Figure 7 As shown, TXD2 and RXD2 are data communication pins, RST1 is the module reset pin, and RING is the data reception wake-up pin.

[0036] The specific settings of the 4G communication circuit are as follows: Figure 8 As shown, TXD3 and RXD3 are data communication pins, RST2 is the module reset pin, and CARD1 is the SIM card.

[0037] The device in this application adopts a multi-channel communication mechanism, prioritizing data transmission via the 4G network. When the 4G network communication fails, the LoRa Mesh network is used for data communication. The LoRa Mesh network only transmits data; the collected image information is stored in the device and will be transmitted again once the 4G network is restored.

[0038] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
