Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a solar-powered low-power camera. Background Art

[0002] Currently, the most common cameras on the market can only operate normally when there is a mains power supply and a fiber optic network. However, in remote wilderness areas, areas without electricity, remote mountain villages, as well as rural areas, islands, and remote regions with underdeveloped transportation where there are no power transmission lines erected and no power generation and supply facilities.

[0003] Currently, compared with thermal power generation, the cost of power generation is high, so it is difficult for individuals to generate electricity. Moreover, there are no fiber optic network wiring facilities. For farms, individuals, or units with important and special confidentiality requirements, the cost of sending personnel to monitor the site is high. For example, in harsh weather conditions such as day and night rain, snow, etc., personnel are prone to fatigue, and the monitoring effect may not be good. Therefore, it is necessary to use low-power cameras for monitoring to provide better security for property or personnel and also reduce the application cost. Based on this, a solar-powered low-power camera is proposed to solve the above problems. Summary of the Utility Model

The camera body 5 also supports night infrared light compensation, with a support distance of 15 meters, and supports automatic switching between night and day vision. Even in the black night, it can clearly see the monitored images, providing a safe care effect and ensuring the field environment.

[0021] A PIR induction module is installed at the bottom of the control box 2, and it is electrically connected to the MCU through a wire. An alarm module and an LED infrared light board are also installed in the control box 2, and both are electrically connected to the microcontroller. As an optional technical solution of the present invention, the PIR induction module is a sensor that can detect infrared rays emitted by the human body and output an electrical signal, and is used to monitor the surrounding moving personnel. When the PIR induction module senses that a person or an object is moving, the machine starts to run. When there is no response in the environment or the APP does not enter the viewing monitoring state, the device enters the sleep state to save power.

[0022] An SD card, a microphone, and a speaker are installed on the processing circuit board 7, and the SD card, the microphone, and the speaker are all electrically connected to the microprocessor. As an optional technical solution of the present invention, the microphone inputs the voice for intercom, the speaker outputs the voice, and when the alarm module detects abnormal sounds or abnormal images in the device, it issues an alarm to external personnel. At the same time, it can also issue a voice warning through the mobile phone and make a sound through the speaker, which has a deterrent effect on driving away foreign objects or personnel.

[0023] The communication module is integrated with a 5G module and GPRS / GPS antennas. A mobile SIM card chip is installed inside the 5G module. The GPRS / GPS antennas are used for two-way information exchange with the external Internet. As an optional technical solution of the present utility model, this facilitates the two-way information exchange between the 5G module and the external Internet through the GPRS antenna, and facilitates the user to establish an information connection link between the mobile phone APP and the 5G module to remotely and real-time view the captured video or review the previous monitoring.

[0024] The power supply management module includes a charging circuit and a current protection circuit. The charging circuit and the current protection circuit are electrically connected to multiple storage batteries 6. The power calculation module includes a power calculation circuit. As an optional technical solution of the present utility model, the storage batteries 6 are all lithium batteries with a relatively large energy density. The power meter circuit uses the chip CW2017 for high-precision power calculation, adopts I2C serial data control, tracks the operating conditions of the lithium batteries, and executes the most advanced algorithms to calculate different battery chemical systems. It has a 14-bit Sigma-Delta ADC, a precision voltage reference, and a built-in NTC bias circuit. The IC issues an interrupt alarm signal, and the mainframe of the chip measures the temperature to report reaching the pre-programmed threshold, characterizes the data, and measures the battery voltage and temperature. It can achieve high-precision calculation by the microprocessor and extend the battery life.

[0025] The battery protection circuit adopts a protection circuit for single-cell built-in MOSFET rechargeable lithium batteries with a high-precision lithium battery protection chip (DW02A). It integrates high-precision overvoltage, charging protection, overvoltage discharge protection, overcurrent discharge protection and other performances. Overcharge and over-discharge self-recovery, temperature measurement, and resistance measurement are carried out by detecting the voltage at the VDD or VM terminal (relative to the GND terminal) for overcharge / discharge protection. When the overcharge / discharge protection condition occurs, the built-in N-MOS changes from conduction to cut-off, thus stopping the charge / discharge process.

[0026] The operating principle of the power calculation circuit is as follows:

[0027] The positive electrode of the lithium battery BAT is connected to the 2nd pin (battery voltage monitor I / O) of the U1 (CW2017) chip through the resistor R1, and the 3rd pin (power supply pin) of the U1 chip is powered through the resistor R2. The serial clock data input pins of the U1, the 7th pin (SDA) and the 8th pin (SCL), are connected to the microprocessor controller through resistors. For the stable reading of the clock signal, the microprocessor reads the data of the internal charge and discharge curve graph of the power chip through the SDA / SCL clock signal, accurately grasps the current and voltage state of the camera, and better ensures the operation of the device power supply. The temperature of the chip is read. The 6th pin of the U1 is connected to the 3rd pin (power input pin) of the current protection chip U2 (DV02A) of the NTC varistor R16 and the capacitor C11 through the resistor. The 2nd pin of the U1 (single-chip microcomputer interrupt signal control alarm) is connected to the INT control pin of the MCU to receive the protection information control of overcurrent and overload during charging. The 1st pin (ID) of the U1 is connected to the ground (GND) through a resistor. The resistors R7 and R8 are the 1.8V pull-up voltages of the SDA / SCL of the chip U1. The JPIO control pin of the microprocessor is connected to the ESD1 and ESD2 through the resistor R14 to discharge the static electricity of the 7th and 8th pins to the ground respectively, better ensuring the transmission of a clean clock signal.

[0028] The CPU_BATT_PWR_EN pin of the microprocessor is connected to the D pin of the Q1 (NMOS) transistor through the resistor R13, and from the G pin to the 2nd pin of the fuel gauge chip U1. When a high level is received, it conducts and starts charging. When a low level of the microprocessor is received, Q1 cuts off. When the lithium battery charging is saturated, it will stop overcharging. When the chip U2 receives the battery charging overload of the power chip U1, the chip U2 sends out a low-level signal, and then it will charge the lithium battery. When it is saturated, it will also stop charging. When receiving an external impact and the current is too large, it will protect the battery. The 2nd pin of the battery charge and discharge protection chip U2 (DW02A) is connected to the positive electrode of the lithium battery through the resistor R18 to protect the battery against overcurrent and overvoltage. The capacitors C13 and C14 filter out the voltage ripple for the power supply of the 3rd pin of the U2, making the voltage cleaner and more stable.

[0029] The solar energy component includes a photovoltaic panel 3 and an inverter-rectifier module, which is electrically connected to the power supply management module. As an alternative technical solution of the present invention, the photovoltaic panel 3 is used to convert solar energy into electrical energy. Through the inverter-rectifier module, the output voltage of the photovoltaic panel 3 is converted into 5V direct current, which is convenient for supplying stable electrical energy to the storage battery 6 and the processing circuit board 7.

[0030] In summary, when in use, the user provides stable power supply for the processing circuit board 7, multiple storage batteries 6 and the camera body 5 by setting the solar energy component, the power supply management module and the power calculation module. By setting the microcontroller, it is used to process the external power management data and communication data. At the same time, it conducts two-way information exchange with the external Internet through the communication module. The PIR sensing module detects the infrared rays emitted by the human body in the surrounding environment, facilitating the sending of control signals to the MCU for waking up the camera body 5 and monitoring the surrounding environment through shooting. Subsequently, the alarm module emits a sound through the speaker to give a warning to the outside, and at the same time sends a notification signal to the client through the communication module to inform the maintenance personnel. The whole process is simple and fast, and can conduct round-the-clock monitoring in uninhabited areas, avoiding the maintenance personnel from coming to the scene in person and reducing the application cost.
