Detailed implementation manners
[0037] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0038] Currently, there are mainly two types of solar cell cameras. One is to add a solar panel and a battery to an ordinary camera; the other is to add a solar panel and a battery to an associated low-power quick-start camera. However, the design of ordinary cameras usually does not consider the power issue. Usually, maximizing functions is taken as the competitive advantage of the product, which often results in a short battery life of the camera and is only applicable to areas with sufficient sunlight. It has great limitations in areas with insufficient sunlight. Since the associated low-power quick-start camera only starts to output pictures when the sensor is triggered, its battery life is often long, but it does not record pictures all the time, which often gives customers a low sense of reliability. Moreover, there is indeed a probability of false triggering and non-triggering, resulting in the loss of some important pictures, such as bad weather. Therefore, there is no product in the prior art that combines low power consumption and full-time video recording.
[0039] Based on the above problems, the present utility model provides a camera device. When the camera is in a non-working state, the trigger power supply signal is used to trigger the power-on of the processing module at regular intervals, so that the camera records videos at regular intervals. After the regular video recording, the low frame rate is made into full-time video recording. When the camera needs to work, the trigger power supply signal is used to continuously trigger the power-on of the processing module, so that the camera continuously records videos, realizing the coexistence of the two functions of low power consumption and full-time video recording, and improving the usability and standby time of the product.
[0040] The following will describe the camera device of the present utility model in conjunction with Figures 1 - 13 the description of the camera device of the present utility model.
[0041] Figure 1 is one of the connection schematic diagrams of the camera device provided by the present utility model. As Figure 1 shown, the camera device 100 includes: a first control module 110, a second control module 120, a processing module 130, and a radio frequency module 140, where:
[0042] The first control module 110 is respectively connected to the second control module 120, the processing module 130, and the radio frequency module 140, and the second control module 120 is connected to the processing module 130;
[0043] The processing module 130 is used to generate a camera working state signal; the radio frequency module 140 is used to generate the camera working state signal;
[0044] The second control module 120 is used to generate the trigger power supply signal at regular intervals when the first control module 110 does not receive the camera working state signal, and trigger the processing module 130 to power on at regular intervals through the trigger power supply signal; the trigger power supply signal is used to trigger the processing module 130 to power on;
[0045] The first control module 110 is used to generate an interrupt signal and a wake-up signal based on the camera working state signal sent by the processing module 130 and / or the radio frequency module 140; the interrupt signal is used to interrupt the second control module 120 from generating the trigger power supply signal at regular intervals, and the wake-up signal is used to control the second control module 120 to continuously generate the trigger power supply signal.
[0046] It should be noted that the camera working state signal is a switching control signal for the camera to switch to the working state. If the camera working state signal is generated, it indicates that the camera needs to switch from the non-working state to the working state. If the camera working state signal is not generated, it indicates that the camera maintains the non-working state.
[0047] It should be noted that the trigger power supply signal can be an active level signal. If the active level signal is high level, the trigger power supply signal is high level. If the active level signal is low level, the trigger power supply signal is low level. The trigger power supply signal can also be an edge trigger signal, such as a rising edge or a falling edge. The present invention does not make specific limitations on the trigger form.
[0048] It should be noted that the timing duration can be a preset value. To ensure the real-time nature of video recording, generally, the timing duration can be 900 milliseconds, 800 milliseconds, etc. That is to say, every 900 milliseconds or 800 milliseconds, the power supply signal triggers the processing module 130 to power on once, enabling the camera to perform timed video recording.
[0049] It should be noted that the RF module 140 may include hardware such as a RF front-end part (such as an amplifier, a filter, a mixer, etc.), a control circuit, an antenna, a RF connector, etc.
[0050] Specifically, when the camera does not need to enter the working state, the second control module 120 generates a trigger power supply signal at regular intervals to trigger the processing module 130 to power on at regular intervals; when the camera needs to enter the working state, the processing module 130 or the RF module 140 generates a camera working state signal and sends it to the first control module 110. The first control module 110 generates an interrupt signal and a wake-up signal based on the camera working state signal and sends them to the second control module 120. The second control module 120 stops the function of generating the trigger power supply signal at regular intervals based on the interrupt signal and continuously generates the trigger power supply signal based on the wake-up signal to continuously supply power to the processing module 130.
[0051] In the present utility model, when the camera is in a non-working state, the timing trigger processing module 130 powers on to enable the camera to perform timed video recording. After the timed video recording, the low frame rate is made into full-time video recording. When the camera needs to work, the processing module 130 is continuously triggered to power on to enable the camera to continuously record video, realizing the coexistence of two functions of low power consumption and full-time video recording, and improving the usability and standby duration of the product.
[0052] Figure 2 is the second connection schematic diagram of the camera device provided by the present utility model, as Figure 2 shown, the camera device 100 further includes a power supply module 150,
[0053] The power supply module 150 is connected to the first control module 110, and the power supply module 150 is used to supply power to the first control module 110, the second control module 120, the processing module 130, and the RF module 140.
[0054] Here, the power supply module 150 may include a solar panel, a battery, and a first charge and discharge management chip. Among them, the solar panel is used to convert sunlight into electrical energy and output direct current. After the direct current is input into the first charge and discharge management chip for regulation, the supply voltage is obtained.
[0055] In the present utility model, the power supply module 150 supplies power to other various modules to ensure the normal operation and working of the camera device.
[0056] Figure 3 This is the third schematic diagram of the connection of the camera device provided by the present utility model. As Figure 3 shown, the first control module 110 includes: a first adjustment circuit 111 and a first single-chip microcomputer 112;
[0057] The first adjustment circuit 111 is respectively connected to the power supply module 150, the first single-chip microcomputer 112, and the radio frequency module 140. The first single-chip microcomputer 112 is respectively connected to the second control module 120, the radio frequency module 140, and the processing module 130;
[0058] The first adjustment circuit 111 is used to adjust the power supply voltages of the power supply module 150 to the first single-chip microcomputer 112 and the radio frequency module 140 respectively. The first single-chip microcomputer 112 is used to receive the camera working state signals generated by the radio frequency module 140 and / or the processing module 130, and generate the interrupt signal and the wake-up signal.
[0059] Here, the first adjustment circuit 111 can be a charge and discharge management chip for battery input / output and solar panel output, or an actual circuit including components such as switching tubes, inductors, diodes, and capacitors. For example, a boost circuit (Boost Chopper, BOOST), a buck circuit (DC-DC, BUCK).
[0060] The first single-chip microcomputer 112 can be any suitable type of single-chip microcomputer, such as the MCS-51 series, the STM32 series, the PIC series, etc.
[0061] Here, the first single-chip microcomputer and the radio frequency module can be connected through an asynchronous transmitter (UART_TX0) and an asynchronous receiver (UART_RX0) to send signals.
[0062] Specifically, the power supply module 150 inputs the output voltage to the first adjustment circuit 111. The first adjustment circuit 111 adjusts the output voltage of the power supply module 150 to obtain the power supply voltages of the first single-chip microcomputer 112 and the radio frequency module 140, and supplies power to the first single-chip microcomputer 112 and the radio frequency module 140 respectively. In addition, after the first single-chip microcomputer 112 in the first control module 110 receives the camera working state signals generated by the radio frequency module 140 and / or the processing module 130, it generates an interrupt signal and a wake-up signal.
[0063] It should be noted that the first single-chip microcomputer 112 must be powered on to generate the interrupt signal and the wake-up signal.
[0064] In the embodiment of the present utility model, the first adjustment circuit 111 is used to supply power to the first single-chip microcomputer 112 and the radio frequency module 140, ensuring the normal operation of the first single-chip microcomputer 112 and the radio frequency module 140. The first single-chip microcomputer 112 is used to generate an interrupt signal and a wake-up signal, so that the processing module 130 ends the timed start mode and enters the continuous on mode, realizing the coexistence of two functions of low power consumption and full-time video recording, and improving the usability and standby time of the product.
[0065] Figure 4 Figure 4 is the fourth connection schematic diagram of the camera device provided by the present utility model. As Figure 4 shown, the second control module 120 includes: a second adjustment circuit 121 and a second single-chip microcomputer 122;
[0066] The second adjustment circuit 121 is respectively connected to the power supply module 150 and the second single-chip microcomputer 122. The second single-chip microcomputer 122 is connected to the first single-chip microcomputer 112. The second adjustment circuit 121 is used to adjust the power supply voltage of the power supply module 150 to the second single-chip microcomputer 122. The second single-chip microcomputer 122 is used to continuously generate the trigger power supply signal based on the interrupt signal and the wake-up signal.
[0067] Here, the second adjustment circuit 121 can be a charge and discharge management chip for battery input and output and solar panel output, or an actual circuit including components such as a switching tube, an inductor, a diode, and a capacitor. For example, a BOOST circuit or a BUCK circuit.
[0068] The second single-chip microcomputer 122 can be any suitable type of single-chip microcomputer, such as the MCS-51 series, the STM32 series, the PIC series, etc.
[0069] Specifically, the power supply module 150 inputs the output voltage to the second adjustment circuit 121. The second adjustment circuit 121 adjusts the output voltage of the power supply module 150 to obtain the power supply voltage of the second single-chip microcomputer 122. Then, after the second single-chip microcomputer 122 receives the interrupt signal and the wake-up signal, it continuously generates a trigger power supply signal to continuously trigger the power-on of the processing module 130, so that the camera keeps recording video.
[0070] It should be noted that the second single-chip microcomputer 122 must be powered on to generate the trigger power supply signal.
[0071] In addition, when the second single-chip microcomputer 122 is powered on, the second single-chip microcomputer 122 is further configured to send a single-chip microcomputer heartbeat signal to the first single-chip microcomputer 112, and the first single-chip microcomputer 112 is further configured to generate a single-chip microcomputer reset signal corresponding to the second single-chip microcomputer 122 when the single-chip microcomputer heartbeat signal is not received. In this way, when the second single-chip microcomputer 122 fails, the first single-chip microcomputer 112 can reset the second single-chip microcomputer 122 in time to ensure the normal operation of the camera.
[0072] In the embodiment of the present invention, the second adjustment circuit 121 is used to supply power to the second single-chip microcomputer 122 to ensure the normal operation of the second single-chip microcomputer 122. After the second single-chip microcomputer 122 receives the interrupt signal and the wake-up signal, it continuously generates the trigger power supply signal, so that the processing module 130 ends the timed start mode and enters the continuous on mode, realizing the coexistence of two functions of low power consumption and full-time video recording, and improving the usability and standby time of the product.
[0073] Figure 5 It is the fifth connection schematic diagram of the camera device provided by the present invention, as Figure 5 shown, the processing module 130 includes: a third adjustment circuit 131 and a chip 132;
[0074] The third adjustment circuit 131 is respectively connected to the power supply module 150, the second single-chip microcomputer 122 and the chip 132. The chip 132 is connected to the second single-chip microcomputer 122. The third adjustment circuit 131 is configured to adjust the power supply voltage of the chip 132 by the power supply module 150 based on the trigger power supply signal of the second single-chip microcomputer 122, and the chip 132 is configured to generate the camera working state signal.
[0075] Here, the third adjustment circuit 131 can be a charge and discharge management chip for battery input and output and solar panel output, or an actual circuit including components such as switching tubes, inductors, diodes, and capacitors. For example, BOOST circuit, BUCK circuit.
[0076] Here, the chip 132 can include: digital chips, analog chips, hybrid chips, etc. The embodiment of the present invention does not limit this.
[0077] Here, the chip 132 and the second single-chip microcomputer 122 can be connected through an asynchronous transmitter (UART_TX0) and an asynchronous receiver (UART_RX0).
[0078] Here, the third adjustment circuit 131 and the second single-chip microcomputer 122 can be connected through MCU1_IO to send a trigger power supply signal.
[0079] Specifically, the power supply module 150 inputs the output voltage to the third regulation circuit 131. When the third regulation circuit 131 receives the trigger power supply signal from the second single-chip microcomputer 122, it converts the voltage output by the power supply module 150 to obtain the power supply voltage for the chip 132, supplies power to the chip 132, and then the chip 132 generates a camera working state signal.
[0080] It should be noted that the chip 132 must be powered on to generate the camera working state signal.
[0081] In the embodiment of the present invention, when the third regulation circuit 131 receives the trigger power supply signal from the second single-chip microcomputer 122, it converts the voltage signal output by the power supply module 150, supplies power to the chip 132, and ensures the normal operation of the chip 132. The chip 132 generates a camera working state signal, controls the first single-chip microcomputer 112 to generate an interrupt signal and a wake-up signal, and after using the interrupt signal and the wake-up signal, controls the second single-chip microcomputer 122 to continuously generate the trigger power supply signal, so that the processing module 130 ends the timing start mode and enters the continuous on mode, realizing the coexistence of the two functions of low power consumption and full-time video recording, and improving the usability and standby time of the product.
[0082] Figure 6 It is the sixth connection schematic diagram of the camera device provided by the present invention. As Figure 6 shown, the camera device further includes: a first control circuit 160;
[0083] The first end of the first control circuit 160 is connected to the second regulation circuit 121, the second end of the first control circuit 160 is connected to the chip 132, the third end of the first control circuit 160 is connected to the first regulation circuit 111, and the fourth end of the first control circuit 160 is connected to the first single-chip microcomputer 112;
[0084] The camera working state signal sent by the chip 132 is used to control the switching tube of the first control circuit 160 to be in the on state, so that the first single-chip microcomputer 112 generates the interrupt signal and the wake-up signal.
[0085] Figure 7 It is the connection schematic diagram of the first control circuit provided by the present invention. As Figure 7 shown, the first control circuit 160 includes: a resistor R1, a resistor R2, a resistor R3, a resistor R4, a Metal-Oxide-Semiconductor (MOS) transistor Q1, and a capacitor C1. The first end of the resistor R1 is respectively connected to the chip 132 (i.e., Figure 7The source (S) of the MOS transistor Q1 and the second end of the resistor R1 are respectively connected to the second regulating circuit 121 (i.e., Figure 7 the VDD3V3_RTC interface in), and the first end of the resistor R2. The second end of the resistor R2 is respectively connected to the first end of the capacitor C1 and the first end of the resistor R3. The second end of the capacitor C1 and the second end of the resistor R3 are both grounded. The first end of the resistor R3 is connected to the gate (Gate, G) of the MOS transistor Q1. The drain (Drain, D) of the MOS transistor Q1 is respectively connected to the first end of the resistor R4 and the first single-chip microcomputer 112 (i.e., Figure 7 the SOC_WAKE_MCUO interface in), and the second end of the resistor R4 is connected to the output end of the first regulating circuit 111 (i.e., Figure 7 the VDD3V3 interface in).
[0086] Here, the camera working state signal can be a low-level signal. After the chip 132 sends the camera working state signal to the first control circuit 160, a voltage difference is formed with the output voltage of the second regulating circuit 121, thereby turning on the MOS transistor in the first control circuit 160 and enabling the first single-chip microcomputer 112 to generate an interrupt signal and a wake-up signal.
[0087] In the embodiment of the present invention, by using the camera working state signal sent by the chip 132 to control the switching transistor of the first control circuit 160 to be in the on state, so that the first single-chip microcomputer 112 generates an interrupt signal and a wake-up signal, the coexistence of the two functions of low power consumption and full-time video recording is further realized, and the usability and standby time of the product are improved.
