Description

Technical Field

[0001] The utility model belongs to the technical field of power consumption control, and in particular relates to a photoelectric deflectometer. Background Art

[0002] The photoelectric deflectometer is an imaging recognition technology that utilizes optical lenses, image sensors, controllers, and other components. It calculates the displacement change of the measured point by identifying the change in the imaging position of the measured point in the image. The measured point is equipped with an actively emitting infrared target light with a central wavelength of 850nm, which requires a long power supply. Although there are also deflectometer systems using passive targets on the market, in certain specific environments, such as dense fog and rainy days, actively emitting light source targets have more advantages due to their stronger penetration and anti-interference capabilities. However, the disadvantage of actively powered infrared targets is that the target needs to be powered for a long time, resulting in excessive energy consumption of the system. For outdoor use, photovoltaic cells are used for power supply, which is difficult and costly. Utility Model Content

[0025] In one embodiment of the present invention, Figure 1 As shown, a photoelectric deflectometer includes an infrared target assembly and a photoelectric deflectometer assembly electrically connected to each other, the infrared target assembly includes a first power supply assembly, an LDO assembly 5 and a DC-DC assembly 4 electrically connected to the first power supply assembly, a first MCU assembly 6 electrically connected to the LDO assembly 5 and the DC-DC assembly 4, a first LoRa assembly 8 electrically connected to the first MCU assembly 6, and an infrared target lamp 7 electrically connected to the DC-DC assembly 4, the photoelectric deflectometer assembly includes a second power supply assembly, a second MCU assembly 10 electrically connected to the second power supply assembly, and a 4G transmission assembly 14, a second LoRa assembly 17, an RTC 15, and an image sensor 18 respectively electrically connected to the second MCU assembly 10, the first MCU assembly 6 is electrically connected to the second MCU assembly 10, and the first LoRa assembly 8 is electrically connected to the second LoRa assembly 17;

[0026] Specifically, the LDO component 5 is an LDO power supply device, which outputs a voltage of 3.3V. The DC-DC component 4 is specifically a boost module, which is specifically a 3.7V to 12V circuit. The first MCU component 6 is the control processor of the infrared target light 7. The second MCU component 10 is the control processor of the photoelectric deflectometer. The infrared target light 7 is specifically an 850nm infrared light with a parameter of 12V3W. The first LoRa component 8 is specifically a LoRa communication device. The 4G transmission component 14 is used to realize the transmission of wireless signals and can upload the data collected by the photoelectric deflectometer to the platform server. The second LoRa component 17 has the same functional structure as the first LoRa component 8. The RTC15 is specifically a real-time clock component, which adopts an IIC interface and is used to send a timing interrupt signal. The image sensor 18 is used to collect data of the infrared target light 7.

[0027] The RTC 15 is used to issue a timing interrupt signal, the second MCU component 10 is used to receive the timing interrupt signal, control the second LoRa component 17 to issue a sleep instruction and control the image sensor 18 to be in sleep mode or issue a wake-up instruction and control the image sensor 18 to enter a working mode, and the first MCU component 6 is used to receive the timing interrupt signal, control the first LoRa component 8 to issue a sleep instruction and control the infrared target light 7 to be in sleep mode or issue a wake-up instruction and control the infrared target light 7 to enter a working mode;

[0028] Specifically, when the acquisition time is reached, the RTC generates a timing interrupt signal, triggering the first MCU component 6 and the second MCU component 10 to wake up. At this time, the first MCU component 6 and the second MCU component 10 drive each peripheral to work, and at the same time, a wake-up instruction is issued through the first LoRa component 8 and the second LoRa component 17 to wake up each infrared target light 7 to start working, and at the same time wake up the image sensor 18 to collect data;

[0029] When not collecting, the infrared target component and the photoelectric deflectometer component are both in a low-power sleep state, and only the first LoRa component 8 and the second LoRa component 17 are in the monitoring mode. At the same time, after the collection process is completed, the first MCU component 6 and the second MCU component 10 receive the sleep instruction, turn off the voltage of the infrared target lamp and enter the sleep standby monitoring state, and the photoelectric deflectometer also enters the sleep mode, that is, the image sensor 18 is in sleep mode, and the entire system enters the low-power sleep state again;

[0030] It should also be noted that the first LoRa component 8 and the second LoRa component 17 can be the same LoRa component, that is, only one LoRa component is retained in the entire system. At the same time, the first MCU component 6 and the second MCU component 10 can also be the same MCU component. In the entire system, the system wake-up and sleep processes can also be achieved through a single LoRa component and MCU component.

[0031] In this embodiment, the first power supply assembly includes a first solar panel 2 , a first charging manager 1 electrically connected to the first solar panel 2 , and a lithium battery 3 electrically connected to the first charging manager 1 .

[0032] In this embodiment, the parameters of the first solar panel 2 are 5V / 3W, and the parameters of the lithium battery 3 are 3.7V / 20AH.

[0033] In this embodiment, the second power supply component includes a second charging manager 11 and a second solar panel 13 and a lead-acid battery 15 electrically connected to the second charging manager 11 respectively.

[0034] In this embodiment, the parameter of the second solar panel 13 is 12V / 30W, and the parameter of the lead-acid battery 15 is 12V.

[0035] In this embodiment, a communication antenna 9 is electrically connected to one side of the first LoRa component 8;

[0036] Specifically, the communication antenna 9 facilitates the transmission of sleep signals and wake-up signals.

[0037] In this embodiment, the image sensor 18 is specifically a CMOS image sensor, and one side of the image sensor 18 is electrically connected to an optical lens 19;

[0038] Specifically, the data of the infrared target light 7 is collected through the optical lens 19 and sorted and sent through the image sensor 18 .

[0039] In this embodiment, UART1 is used for communication between the first LoRa component 8 and the first MCU component 6 , and between the second LoRa component 17 and the second MCU component 10 .

[0040] In this embodiment, the model of the 4G transmission component 14 is EC20, and the 4G transmission component 14 uses UART2 communication.

[0041] In this embodiment, one side of the second MCU component 10 is electrically connected to an SD memory 16;

[0042] Specifically, after the system acquisition work is completed, the data of the photoelectric deflectometer can be stored in the SD memory 16, and the SD memory 16 uses an SPI interface.

[0043] It should be noted that, in the entire system, after adopting this solution, the problem solved is the excessive power consumption of the traditional system. In the traditional system solution, only one infrared target is powered by 12V, and the power consumption per day is 0.25A*24h=6Ah. After using this solution, based on 24 working times a day and 1 minute each time, the power required for a single infrared target lamp is only 0.25*0.5h=0.125Ah, less than 3% of the original power consumption, and can be met by a small photovoltaic system, which greatly reduces the system power consumption and the cost of the power supply system.

[0044] The photoelectric deflectometer component also adopts a timed sleep mode, with a built-in RTC15 for interrupt wake-up. In the non-collection state, it sleeps with low power consumption and works only when it is working. Under the traditional solution, the photoelectric deflectometer is powered by 12V and consumes 0.3*24=7.2Ah per day. After adopting this solution, the daily power consumption is 0.3A*0.5h+0.02A*23.5h=0.62Aah, which is less than 10% of the original

[0045] In summary, the photoelectric deflectometer in the above-mentioned embodiment of the present invention sends a timing interrupt signal through RTC15, and the first MCU component 6 and the second MCU component 10 can send corresponding sleep instructions or wake-up instructions according to the timing interrupt signal. When the photoelectric deflectometer needs to perform collection work, the wake-up instruction is used to control the infrared target light 7 and the image sensor 18 to enter the working state to complete the data collection process. After the collection is completed, the sleep instruction can be used to control the infrared target light 7 and the image sensor 18 to enter the sleep state, thereby reducing the total power consumption of the system. The present invention adopts the method of powering on during operation and powering off during non-collection, which greatly reduces the system power consumption compared with the traditional long power supply solution.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
