Similarly, the following examples are only partial embodiments of the present invention rather than all embodiments, and all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] Traditional self-cleaning systems, especially those for video equipment, are mainly used for video equipment installed at high altitudes. It is difficult to add water to the water tank of the cleaning system and manual water addition is required, which has high maintenance costs and easily leads to waste of water resources.

[0025] Therefore, a liquid circulation cleaning system is provided, which utilizes the first cleaning liquid in the first cleaning liquid tank to clean the camera equipment, collects the second cleaning liquid generated by cleaning the camera equipment through a recovery component, and injects the third cleaning liquid obtained by decontamination of the second cleaning liquid into the first cleaning liquid tank, and then in the process of injecting into the first cleaning liquid tank, part of the third cleaning liquid is used to clean the camera equipment, thereby realizing the sequential utilization of liquid and reducing the waste of liquid resources. In the process of the sequential two-way flow of liquid, the camera equipment can be cleaned, thereby effectively improving the camera effect and reducing maintenance costs.

[0026] See also Figure 1 , Figure 1 It is a structural schematic diagram of the first embodiment of the liquid circulation cleaning system in this application.

[0027] like Figure 1 As shown, the liquid circulation cleaning system 10 includes: a first cleaning liquid tank 100, a cleaning component 200 and a recovery component 300; the cleaning component 200 is connected to the first cleaning liquid tank 100 through a pipeline, and is used to use the first cleaning liquid in the first cleaning liquid tank to clean the camera device; the recovery component 300 is connected to the first cleaning liquid tank 100 and the cleaning component 200 through a pipeline, and is used to collect the second cleaning liquid generated by cleaning the camera device, and decontaminate the second cleaning liquid, and inject the third cleaning liquid obtained after the decontamination treatment into the first cleaning liquid tank 100 through the pipeline; wherein, the cleaning component 200 is also used to inject the third cleaning liquid into the first cleaning liquid tank 100, and use part of the third cleaning liquid to clean the camera device.

[0028] Among them, the first cleaning liquid tank 100 can be set inside the camera device as a water tank for storing cleaning liquid internally; the cleaning component 200 can be set outside the camera device for cleaning the camera device, such as cleaning the lens of the camera device; the recovery component 300 can be set outside the camera device for recovering the second cleaning liquid generated by the cleaning component 200 when cleaning the camera device.

[0029] It is understandable that the first cleaning liquid can be a clean cleaning liquid, such as clean water; the second cleaning liquid can be a liquid produced after cleaning, such as sewage; and the third cleaning liquid can be a cleaning liquid after decontamination treatment, such as clean water.

[0030] Specifically, the cleaning component 200 is connected to the first cleaning liquid tank 100 through a pipeline. When the camera equipment needs to be cleaned, the first cleaning liquid in the first cleaning liquid tank 100 is controlled to flow to the cleaning component 200, so that the first cleaning liquid is sprayed toward the camera equipment through the cleaning component 200, and then the camera equipment is cleaned; and the second cleaning liquid generated by cleaning the camera equipment is sampled and recovered by the recovery component 300, and then the second cleaning liquid is decontaminated by the recovery component 300 to obtain a clean and contaminant-free third cleaning liquid, and the recovery component 300 then injects the third cleaning liquid into the first cleaning liquid tank 100 to realize liquid circulation in the cleaning system and effectively reduce the waste of water resources; and in the process of injecting the third cleaning liquid into the first cleaning liquid tank 100, part of the third cleaning liquid can also be used to clean the camera equipment through the cleaning component 200, to realize cleaning treatment in the two-way flow process, effectively reduce maintenance costs, and thus improve the camera effect.

[0031] See also Figure 2 , Figure 2 It is a structural schematic diagram of the second embodiment of the liquid circulation cleaning system in this application.

[0032] like Figure 2 As shown, the liquid circulation cleaning system 10 includes: a first cleaning liquid tank 100, a cleaning component 200, a recovery component 300 and a control module 400; the cleaning component 200 is connected to the first cleaning liquid tank 100 through a pipeline; the recovery component 300 is connected to the first cleaning liquid tank 100 and the cleaning component 200 through a pipeline; the control module 400 is connected to the pipeline between the first cleaning liquid tank 100 and the cleaning component 200, and uses a first control signal to control the first cleaning liquid in the first cleaning liquid tank 100 to clean the imaging device, or uses a second control signal to control the third cleaning liquid to clean the imaging device.

[0033] Specifically, a first control signal is used to control the first cleaning liquid in the first cleaning liquid tank 100 to clean the imaging device. Specifically, the first control signal is used to control the first cleaning liquid in the first cleaning liquid tank 100 to flow out of the first cleaning liquid tank 100, and when flowing through the cleaning component 200, the imaging device is cleaned by the cleaning component 200; a second control signal is used to control the third cleaning liquid to clean the imaging device. Specifically, the second control signal is used to control the third cleaning liquid to be injected into the first cleaning liquid tank 100, and when flowing through the cleaning component 200, the imaging device is cleaned by the cleaning component 200; that is, when the cleaning liquid flows out of or flows to the first cleaning liquid tank, it will flow through the cleaning component 200, thereby achieving that the cleaning liquid flowing out of or flowing to the first cleaning liquid tank can clean the imaging device, thereby improving the cleaning efficiency.

[0034] In some embodiments, the cleaning component 200 may be an outlet for the cleaning liquid and may correspond to an imaging device, such as a nozzle, so that the first cleaning liquid or the third cleaning liquid flowing through the nozzle may be sprayed out from the nozzle to clean the imaging device.

[0035] In some embodiments, continue to refer to Figure 2 The control module 400 may include a motor assembly 410 and a control assembly 420, wherein the motor assembly 410 is connected to the pipelines of the first cleaning liquid tank 100 and the cleaning assembly 200, and the control assembly 420 is connected to the motor assembly 410; in response to a first control signal, the motor assembly 410 rotates in a first direction to control the first cleaning liquid in the first cleaning liquid tank 100 to flow to the cleaning assembly 200 and clean the camera device, or in response to a second control signal, the motor assembly 410 rotates in a second direction to control the third cleaning liquid to be injected into the first cleaning liquid tank 100.

[0036] Among them, the motor assembly 410 can be a motor rotating device, such as a water pump motor, which is used to control the forward flow or reverse flow of the cleaning liquid in the pipeline of the first cleaning liquid tank 100 and the cleaning assembly 200; for example, setting the cleaning liquid to flow from the first cleaning liquid tank 100 to the cleaning assembly 200 is a forward flow, and setting the cleaning liquid to flow into the first cleaning liquid tank 100 is a reverse flow.

[0037] It can be understood that the rotation of the motor assembly 410 along the first direction may be a forward rotation of the motor assembly, and correspondingly, the rotation of the motor assembly 410 along the second direction may be a reverse rotation of the motor assembly.

[0038] Specifically, after receiving the first control signal, the control component 420 can control the motor component 410 to rotate in the first direction, that is, the motor component 410 rotates forward in response to the first control signal to control the first cleaning liquid in the first cleaning liquid tank 100 to flow out, and the first cleaning liquid cleans the camera device when it flows through the cleaning component 200; or after receiving the second control signal, the control component 420 can control the motor component 410 to rotate in the second direction, that is, the motor component 410 rotates reversely in response to the second control signal to control the third cleaning liquid to be injected into the first cleaning liquid tank 100, and when the third cleaning liquid flows through the cleaning component 200, part of the third cleaning liquid is used to clean the camera device.

[0039] In some embodiments, the control component 420 includes a first drive unit and a second drive unit, wherein the first drive unit includes a first field effect transistor M1 and a second field effect transistor M4, the motor component 410 is respectively connected to the first field effect transistor M1 and the fourth field effect transistor M4, and the first field effect transistor M1 is connected to the fourth field effect transistor M4 to form a first loop; the second drive unit includes a second field effect transistor M2 and a third field effect transistor M3, the motor component 410 is respectively connected to the second field effect transistor M2 and the third field effect transistor M3, and the second field effect transistor M2 is connected to the third field effect transistor M3 to form a second loop.

[0040] The connection relationship of the field effect transistors is as follows: the first field effect transistor is connected to the power supply through the first pole of the first field effect transistor, connected to the control signal generating component through the second pole of the first field effect transistor, and connected to the motor component through the third pole of the first field effect transistor; the second field effect transistor is connected to the third pole of the first field effect transistor through the first pole of the second field effect transistor, connected to the control signal generating component through the second pole of the second field effect transistor, and grounded through the third pole of the second field effect transistor; the third field effect transistor is connected to the power supply through the first pole of the third field effect transistor, connected to the control signal generating component through the second pole of the third field effect transistor, and connected to the motor component through the third pole of the third field effect transistor; the fourth field effect transistor is connected to the third pole of the third field effect transistor through the first pole of the fourth field effect transistor, connected to the control signal generating component through the second pole of the fourth field effect tube, and grounded through the third pole of the fourth field effect tube.

[0041] It can be understood that the first electrode is the drain, the second electrode is the gate, and the third electrode is the source.

[0042] Specifically, in response to a first control signal, a first circuit consisting of a motor assembly, a first field effect transistor and a fourth field effect transistor is turned on, so that the motor assembly rotates in a first direction, i.e., forward rotation, to control the outflow of the first cleaning liquid in the first cleaning liquid tank 100, and the first cleaning liquid cleans the imaging device when flowing through the cleaning assembly 200; or in response to a second control signal, a second circuit consisting of a motor assembly, a second field effect transistor and a third field effect transistor is turned on, so that the motor assembly rotates in a second direction, i.e., reverse rotation, to control the injection of the third cleaning liquid into the first cleaning liquid tank, and use part of the third cleaning liquid to clean the imaging device when flowing through the cleaning assembly 200.

[0043] In this embodiment, when the cleaning liquid flows out of or flows into the first cleaning liquid tank, it will flow through the cleaning assembly, so that the cleaning liquid flowing out of or flowing into the first cleaning liquid tank can clean the imaging device, thereby improving the cleaning efficiency.

[0044] In some embodiments, continue to refer to Figure 2 The liquid circulation cleaning system 10 may further include: a feedback module 500, and the feedback module 500 is connected to the control module 400 and the first cleaning liquid tank respectively.

[0045] Among them, the feedback module 500 is used to obtain the storage amount of the first cleaning liquid in the first cleaning liquid tank 100, and obtain the current value of the motor component in the control module 400, and use the storage amount and current value to generate a feedback signal, and then use the feedback signal to determine the first control signal and the second control signal.

[0046] For example, during the forward rotation of the motor assembly, the corresponding forward current value is obtained, and when the storage amount of the first cleaning liquid in the first cleaning liquid tank 100 is lower than the minimum storage amount, the feedback module determines the second control signal using the forward current value and the storage amount, and feeds the second control signal back to the control module to enable the second circuit to be turned on, thereby controlling the motor assembly to rotate in the opposite direction, so as to control the injection of the third cleaning liquid into the first cleaning liquid tank; or during the reverse rotation of the motor assembly, the corresponding reverse current value is obtained, and when the storage amount of the first cleaning liquid in the first cleaning liquid tank is higher than the maximum storage amount, the feedback module determines the first control signal using the reverse current value and the storage amount, and feeds the first control signal back to the control module to enable the first circuit to be turned on, thereby controlling the motor assembly to rotate in the opposite direction, so as to control the outflow of the first cleaning liquid in the first cleaning liquid tank.

[0047] In some embodiments, the feedback module 500 includes: a sampling circuit 510 and a control signal generating component 520, the sampling circuit 510 is connected to the control module 400, and is used to obtain the current value of the motor component in the control module 400; the control signal generating component 520 is respectively connected to the sampling circuit 510, the first cleaning liquid tank 100 and the control module 400, the control signal generating component receives the current value and the storage amount, uses the storage amount and the current value to generate a feedback signal, and then uses the feedback signal to determine the first control signal and the second control signal, and feeds the first control signal or the second control signal back to the control module.

[0051] In some embodiments, the sampling circuit may further include a first resistor R1 and a second resistor R2, wherein the first resistor R1 is connected in series to a first input terminal of the first operational amplifier U1, and the second resistor R2 is connected in series to a second input terminal of the first operational amplifier U1; it can be understood that the first input terminal of the operational amplifier refers to the inverting input terminal, and the second input terminal of the operational amplifier refers to the non-inverting input terminal.

[0052] Furthermore, the feedback module 500 may also include a negative power rail generating circuit 530, which is respectively connected to the control module and the sampling circuit, wherein the negative power rail generating circuit 530 is used to generate a negative power rail so that the sampling circuit can sample a negative current when the motor component rotates in the reverse direction, thereby enabling the control signal generating component to determine the second control signal using the negative current.

[0053] See also Figure 3 , Figure 3It is a structural schematic diagram of an embodiment of the negative power rail generating circuit of the present application, including a power supply VIN, a first transistor Q1, a second transistor Q2, a first capacitor C1, a second capacitor C2, a first diode D1 and a second diode D2; the specific connection relationship is: the power supply VIN is connected to the emitter of the first transistor Q1, the collector of the first transistor is connected to the collector of the second transistor Q2, the emitter of the second transistor Q2 is grounded, and the bases of the first transistor Q1 and the second transistor Q2 are connected in parallel and used to receive a pulse (PWM) signal; the connection point of the first transistor and the second transistor is connected to the first capacitor C1, the first diode D1 sampling circuit, such as connected to the first operational amplifier U1, the second diode D2 is connected between the emitter of the second transistor Q2 and the first diode D1, and the second capacitor C2 is connected in parallel to both ends of the first diode and the second diode.

[0057] Specifically, after each cleaning of the camera device by the cleaning component, sewage will be generated. In order to reduce the waste of water resources, the second cleaning liquid tank 310 is set to collect the sewage generated during the cleaning process, and then the sewage collected by the second cleaning liquid tank 310 is transmitted to the liquid treatment component 320 for sewage decontamination treatment to obtain a clean third cleaning liquid, and then the third cleaning liquid is injected into the first cleaning liquid tank 100. It can be understood that the motor component needs to rotate in the opposite direction in response to the second control signal, thereby driving the third cleaning liquid to be injected into the first cleaning liquid tank 100.

[0058] Furthermore, the recovery component 300 may also include a third cleaning liquid tank 330, and the third cleaning liquid tank 330 is connected to the liquid processing component 320, the cleaning component 200 and the first cleaning liquid tank through pipelines.

[0060] In some embodiments, a one-way valve is provided on the pipeline between the third cleaning liquid tank 330 and the liquid processing component 320, so that the third cleaning liquid obtained by the decontamination treatment of the liquid processing component 320 can be unidirectionally injected into the third cleaning liquid tank 330, thereby preventing the first cleaning liquid in the first cleaning liquid tank from flowing to the liquid processing component 320 and affecting the sequential process of the circulation system; at the same time, the third cleaning liquid tank can also collect the first cleaning liquid in the first cleaning liquid tank to clean the camera equipment.

[0061] Specifically, in response to the first control signal, the motor assembly rotates forward, and during the outflow of the first cleaning liquid in the first cleaning liquid tank, the first cleaning liquid flows to the third cleaning liquid tank, and when the first cleaning liquid flows through the cleaning assembly, part of the first cleaning liquid is used to spray from the cleaning assembly to the camera device, thereby cleaning the camera device, and the remaining first cleaning liquid is collected by the third cleaning liquid tank; and in response to the second control signal, the motor assembly rotates reversely, the third cleaning liquid in the third cleaning liquid tank flows to the first cleaning liquid tank, and when the third cleaning liquid flows through the cleaning assembly, part of the third cleaning liquid is used to spray from the cleaning assembly to the camera device, thereby cleaning the camera device, and the remaining third cleaning liquid is collected by the first cleaning liquid tank.

[0062] In this embodiment, the first cleaning liquid in the first cleaning liquid tank is used to clean the camera equipment, the second cleaning liquid generated by cleaning the camera equipment is collected by a recovery component, and the third cleaning liquid obtained by decontamination of the second cleaning liquid is injected into the first cleaning liquid tank, and then in the process of injecting into the first cleaning liquid tank, part of the third cleaning liquid is used to clean the camera equipment, thereby realizing the sequential utilization of liquid and reducing the waste of liquid resources. In the process of the sequential two-way flow of liquid, the camera equipment can be cleaned, thereby effectively improving the camera effect and reducing maintenance costs.

[0070] Among them, the recovery component collects the second cleaning liquid generated by cleaning the camera equipment, and decontaminates the second cleaning liquid to obtain a third cleaning liquid. The second cleaning liquid is a contaminated liquid obtained by cleaning the camera equipment, such as sewage, and the third cleaning liquid is a clean cleaning liquid obtained by decontaminating the second cleaning liquid.

[0071] Specifically, in response to the second control signal, the third cleaning liquid obtained by the recovery component is controlled to be injected into the first cleaning liquid tank, and then during the injection process, part of the third cleaning liquid is used to clean the imaging device.

[0072] Furthermore, it may also include:

[0073] Y100, obtaining the current value of the motor component in the control module, and obtaining the storage amount of the first cleaning liquid in the first cleaning liquid tank.

[0074] The motor assembly is used to control the inflow and outflow of the cleaning liquid in the first cleaning liquid tank, and the storage capacity refers to the current storage capacity of the cleaning liquid in the first cleaning liquid tank.

[0075] Specifically, when the first cleaning liquid flows out of the first cleaning liquid tank, the motor assembly rotates in the forward direction, and the current value obtained is the forward current value; when the third cleaning liquid flows into the first cleaning liquid tank, the motor assembly rotates in the reverse direction, and the current value obtained is the reverse current value, and the current storage amount of the cleaning liquid in the first cleaning liquid tank is obtained.

[0076] Y200, determine a feedback signal using the current value and the storage amount, and use the feedback signal to generate a first control signal or a second control signal.

[0077] Among them, because the current value has a forward current value and a reverse current value, different first control signals and second control signals can be generated.

[0078] Specifically, during the forward rotation of the motor assembly, the corresponding forward current value is obtained, and when the storage amount of the first cleaning liquid in the first cleaning liquid tank is lower than the minimum storage amount, the feedback module uses the forward current value and the storage amount to determine the second control signal, and the second control signal is fed back to the control module to control the reverse rotation of the motor assembly to control the injection of the third cleaning liquid into the first cleaning liquid tank; or during the reverse rotation of the motor assembly, the corresponding reverse current value is obtained, and when the storage amount of the first cleaning liquid in the first cleaning liquid tank is higher than the maximum storage amount, the feedback module uses the reverse current value and the storage amount to determine the first control signal, and the first control signal is fed back to the control module to control the forward rotation of the motor assembly to control the outflow of the first cleaning liquid in the first cleaning liquid tank.

[0079] In some embodiments, in response to the first control signal, during the forward rotation of the motor assembly, the first cleaning liquid can be used to clean the camera device; for example, during the forward rotation of the motor assembly, the wiper in front of the camera device is controlled to work, and then the camera device is cleaned by the first cleaning liquid. At the same time, it can also be determined whether the storage amount of the cleaning liquid in the first cleaning liquid tank is lower than the minimum storage amount. For example, if there is no cleaning liquid in the first cleaning liquid tank, the second control signal is determined so that the motor assembly responds to the second control signal, and during the reverse rotation of the motor assembly, the third cleaning liquid can be used to clean the camera device; for example, during the reverse rotation of the motor assembly, the wiper in front of the camera device is controlled to work, and then the camera device is cleaned by the third cleaning liquid. At the same time, it can also be determined whether the storage amount of the cleaning liquid in the first cleaning liquid tank is higher than the maximum storage amount. For example, if the cleaning liquid in the first cleaning liquid tank is full, the first control signal is determined, and then the motor assembly is driven forward. This can be repeated until the camera device is cleaned.

[0080] In this embodiment, a first control signal is used to control the first cleaning liquid to flow out of the first cleaning liquid tank, and the first cleaning liquid is used to clean the camera device. The second cleaning liquid generated by cleaning the camera device is decontaminated by a recovery component to obtain a third cleaning liquid. Then, a second control signal is used to control the third cleaning liquid to be injected into the first cleaning liquid tank, thereby recycling the cleaning liquid and reducing the waste of liquid resources. In addition, during the circulation of the cleaning liquid, both the forward outflow and the reverse inflow can clean the camera device, thereby effectively improving the camera effect and reducing maintenance costs.
