Description

Technical Field

[0001] The present application relates to the field of security camera modules, and in particular to an IPC monitoring camera module heating and cleaning system and method thereof. Background Art

[0002] With technological advancements, the application areas of IPC network surveillance cameras have become increasingly diverse, and the number of cameras installed has increased rapidly, from outdoor security to indoor home use. This increased demand for outdoor use has led to a more pronounced impact on the outdoor environment. When ambient temperatures are low (such as in winter) and humidity is high, the lens surface temperature drops below the dew point. Water vapor in the air condenses into tiny droplets on the lens surface, causing image blur, reduced contrast, or even complete obstruction of the field of view. Large temperature differences between indoor and outdoor (such as between an air-conditioned room and the outdoors), in the early morning and evening, in high humidity, or in low-temperature environments such as rain and snow, can cause the lens surface to become covered with snow, or rainwater can freeze directly into ice, physically blocking the lens and impairing optical performance.

[0003] Some cameras used in external environments, such as highway surveillance cameras, are installed in high and hard-to-reach locations. Manual cleaning is difficult and the maintenance cost is high. Rainwater attached to the lens surface needs to be cleaned promptly to ensure its imaging effect and thus improve the user experience. Summary of the Invention

[0004] This application aims to provide an IPC surveillance camera module self-cleaning system. When the lens surface is blurred, the user can issue a cleaning command through the remote control module, and the dirt on the lens surface is removed by heating the cleaning module to ensure the imaging quality of the camera equipment.

[0005] To achieve the purpose, the present invention adopts the following technical solutions: A heating and cleaning system for an IPC surveillance camera module comprises at least a lens and a heating and cleaning module arranged on the lens for heating the lens, and further comprises a network module and a remote control module. The network module is used to establish a communication connection between the remote control module and the lens. The remote control module remotely monitors the imaging picture of the lens and can remotely control the heating and cleaning module to heat the lens when water droplets are present in the imaging picture.

[0006] As described above, the IPC monitoring camera module heating and cleaning system has a control board on the lens that is connected to the network module for communication. The heating and cleaning module is electrically connected to the control board. The control board receives cleaning instructions sent by the remote control module through the network module and controls the start / stop of the heating and cleaning module according to the cleaning instructions.

[0007] The IPC monitoring camera module heating and cleaning system as described above, the heating and cleaning module includes a heating element and a temperature sensing element. The heating element is used to heat the lens, and the temperature sensing element feeds back the lens temperature to the control board. When the control board detects that the lens temperature drops to a preset threshold, the heating element is controlled to heat the lens. When the lens temperature rises to the preset threshold, the heating is stopped.

[0008] In the IPC monitoring camera module heating and cleaning system described above, when the temperature sensing component detects that the lens temperature T0 is less than 0°C, the control board controls the heating element to start heating; When the temperature sensing component detects that the lens temperature T1 is greater than 60°C, the control board controls the heating element to turn off heating.

[0009] In the IPC monitoring camera module heating and cleaning system as described above, an image sensor for collecting images is provided on the control board, and the collected images are transmitted to the remote control module via the network module for remote monitoring.

[0010] Another object of the present application is to provide a method for heating and cleaning an IPC surveillance camera module, the method comprising the following steps: The lens acquires an imaging image; Transmit the imaging image to the remote control module through the network module for remote monitoring; When water droplets are present in the imaging image, the heating and cleaning module is remotely controlled to heat the lens.

[0012] The above-mentioned IPC monitoring camera module heating cleaning method further includes the following steps: Get lens temperature; When it is detected that the lens temperature drops to a preset threshold, the lens is heated; When it is detected that the lens temperature rises to a preset threshold, heating of the lens is stopped.

[0013] The IPC monitoring camera module heating cleaning method as described above starts heating when the lens temperature T0 is detected to be less than 0°C; When the lens temperature T1 is detected to be greater than 60°C, the heating is turned off.

[0014] In the above-mentioned IPC monitoring camera module heating cleaning method, an image sensor for collecting images is provided on the control board, and the collected images are transmitted to the remote control module through the network module for remote monitoring.

[0015] Compared with the prior art, the present invention has the following advantages: The present application provides an IPC monitoring camera module heating and cleaning system and method. The system includes a lens, a heating and cleaning module, a network module, and a remote control module.

[0019] An embodiment of the present application provides an IPC monitoring camera module heating and cleaning system, which includes a lens, a heating and cleaning module, a network module, and a remote control module. When the camera module is connected to a host and working, the lens surface becomes blurred due to rain and other factors, and the image clarity is affected. At this time, the user can issue a cleaning command through the remote control module. The camera module body receives the signal and powers the heating and cleaning module. The heating and cleaning module clears the dirt on the lens surface to ensure the imaging quality of the camera equipment.

[0020] Furthermore, the lens 1 is provided with a control board 11 that is communicatively connected to the network module 3. The heating and cleaning module 2 is electrically connected to the control board 11. The control board 11 receives cleaning instructions sent by the remote control module 4 through the network module 3 and controls the start / stop of the heating and cleaning module 2 according to the cleaning instructions. The present application remotely controls the heating of the camera module through the Ethernet module / network module 3. When there are water stains on the image or water droplets on the lens surface, the lens can be heated and dehydrated by remotely controlling the heating module.

[0021] Furthermore, the heating and cleaning module 2 includes a heater 21 and a temperature sensor 22. The heater 21 is used to heat the lens. The temperature sensor feeds back the lens temperature to the control board 11. When the control board 11 detects that the lens temperature has dropped to a preset threshold, it controls the heater 21 to heat the lens. When the lens temperature rises to the preset threshold, heating is stopped. Specifically, the heater 21 is a heating resistor or a heating plate. When the temperature sensor detects that the lens temperature T0 is less than 0°C, the control board 11 controls the heater 21 to start heating. When the temperature sensor detects that the lens temperature T1 is greater than 60°C, the control board 11 controls the heater 21 to stop heating. This application uses a heating and cleaning module 2 to heat the lens 1. The heating module 2 includes a heater 21 and a temperature sensor 22. The heater 21 is used to heat the lens. The temperature sensor feeds back the lens temperature to the main control end. When the main control end detects that the lens temperature has dropped, the heating and cleaning module 2 starts to control the heater 21 to heat the lens. When the lens temperature rises to the set threshold, heating is stopped. As a preferred embodiment of the present application, the heating control and temperature feedback signals are composed of a 6-pin connector, and an FPC or wire is led out from the tail end of the lens 1 and plugged into the camera module PCBA module through the connector.

[0022] Further preferably, the control panel 11 is provided with an image sensor 12 for capturing images.

Examples of the network module 3 include, but are not limited to, the internet, an intranet, a local area network, a mobile communication network, and combinations thereof. The remote control heating module and the network module 3 are closely linked. The remote control controls the heating of the camera module via the Ethernet module / network module 3. When water stains are present in the image or water droplets are present on the lens surface, the remote control heating module can be used to heat and remove water from the lens.

When water droplets are present in the imaging image, the heating and cleaning module 2 is remotely controlled to heat the lens.

[0024] An embodiment of the present application provides an IPC monitoring camera module heating and cleaning method, which includes obtaining an imaging picture and remotely monitoring the picture. When the camera module is connected to the host and working, the lens surface is blurred due to rain and other factors, and the imaging clarity is affected. At this time, the user can issue a cleaning instruction through the remote control module 4. The camera module body receives the signal and powers the heating and cleaning module 2. The heating and cleaning module 2 is used to clean the dirt on the lens surface to ensure the imaging quality of the camera equipment.

[0025] Specifically, "remotely controlling the heating and cleaning module 2 to heat the lens" includes: the control panel 11 on the lens 1 receives the cleaning instructions sent by the remote control module 4 via the network module 3, and the control panel 11 controls the start / stop of the heating and cleaning module 2 according to the cleaning instructions. This application remotely controls the heating of the camera module via the Ethernet module / network module 3. When there are water stains on the image or water droplets on the lens surface, the heating module can be remotely controlled to heat and remove water from the lens.

[0026] Furthermore, the method further comprises the following steps: S4, obtaining the lens temperature; S5. When it is detected that the lens temperature drops to a preset threshold, specifically, when it is detected that the lens temperature T0 is less than 0° C., heating is started to heat the lens; S6. When it is detected that the lens temperature rises to a preset threshold, specifically when it is detected that the lens temperature T1 is greater than 60° C., the heating is turned off and the heating of the lens is stopped.

[0027] This application utilizes a heating and cleaning module 2 to heat the lens 1. The module includes a heater 21 and a temperature sensor 22. The heater 21 is used to heat the lens, and the temperature sensor 22 provides feedback of the lens temperature to the main control terminal. Specifically, the heater 21 is a heating resistor or a heating plate. When the main control terminal detects a decrease in lens temperature, the heating and cleaning module 2 controls the heater 21 to heat the lens. When the lens temperature rises to a set threshold, heating stops. As a preferred embodiment of this application, the heating control and temperature feedback signals are provided by a 6-pin connector. An FPC or wire is connected from the rear end of the lens 1 and plugged into the camera module PCBA module via a connector.

When water stains are present in the image or water droplets are present on the lens surface, the remote control heating module can be used to heat and remove water from the lens.

[0029] The working principle of this application scheme is as follows: when the camera module is connected to the host and working, the surface of the lens 1 is blurred due to rain and other factors, and the image clarity is affected. At this time, the user can issue a cleaning command through the host, and the camera module body receives the signal and supplies power to the cleaning module drive device; when the cleaning is completed, the user ends the cleaning command, the module stops supplying power to the cleaning module drive device, and the cleaning action ends. The working principle is as follows Figure 2 shown.

[0030] This application provides an IPC surveillance camera module heating and cleaning system and method thereof, which adds a lens self-cleaning and heating function to the IPC camera. The core value lies in ensuring the continuous provision of clear and reliable surveillance images, significantly reducing the maintenance work and costs caused by lens contamination, and improving the overall availability, reliability and intelligence level of the system. Although it will increase certain initial costs and complexity, the long-term operation and maintenance benefits and performance guarantees it brings in outdoor, harsh environments or difficult-to-maintain scenarios far outweigh these costs, making it a valuable functional enhancement in modern intelligent video surveillance systems. The choice of self-cleaning technology needs to be weighed according to the specific application environment, pollutant type and cost budget.
