[0060] The present application provides a control method of an energy-saving system, which is mainly applied to the scene of shooting small animals in the wild environment. Of course, in some cases, it can also be used in the scene of shooting small animals indoors. Figure 1 is a first flowchart of the control method of the energy-saving system according to the embodiments of the present application. As shown in Figure 1 In an embodiment of the present application, the control method of the energy-saving system is applied to the scene of shooting small animals in the wild environment. The method comprises the following steps:

[0061] In step S101, when the rechargeable battery completes charging and starts discharging, the discharging voltage is obtained. The specific value of the obtained discharging voltage is determined according to the specification of the rechargeable battery, which is not limited here.

[0062] Step S102, based on the discharge voltage to start MS51 power management unit, sends a first enable signal, control charge and discharge management device for A40I minimum system power supply, wherein A40I minimum system is provided with an infrared sensor for detecting infrared signal, the discharge voltage is the discharge voltage after the anti-inrush protection circuit; wherein the infrared sensor is used for detecting the output of the infrared detection signal when the animal is close to the measured infrared area, of course, in some other embodiments, other detection devices can also be used to detect small animals, which are not limited here; in addition, the anti-inrush protection circuit in this embodiment plays a role in protecting the rechargeable battery, preventing the occurrence of current inrush; that is, in the process of discharging the rechargeable battery, the MS51 power management unit enables the charge and discharge management device to supply power to the A40I minimum system, controls the infrared sensor to detect small animals, so that the MS51 power management unit enters normal working mode.

[0063] In addition, since the person skilled in the art knows that A40I minimum system refers to the simplest circuit for single-chip microcomputer to work normally, the specific working principle is not described here.

[0064] Step S103, MS51 power management unit sends a second enable signal to control the power management device to power the camera equipment, so that the camera equipment takes pictures of animals and transmits the animal pictures to the A40I minimum system through the communication interface, and the A40I minimum system receives and stores the animal pictures; that is, this step enables the power management device to power the camera equipment through the MS51 power management, realizes the purpose of taking pictures and transmitting animal pictures, and makes the camera equipment enter normal working mode; wherein the communication interface of the camera equipment in this embodiment is a USB2.0 interface with fast data transmission rate, of course, in some other examples, the communication interface can also be other interfaces with faster maximum data transmission rate, which are not limited here;

[0065] Step S104, MS51 power management unit sends a third enable signal to control the voltage regulator chip to power the EC200S mobile communication unit; that is, this step enables the power management device to power the EC200S mobile communication module through the MS51 power management unit, realizes the purpose of communication between the MS51 power management unit and the EC200S mobile communication unit, and communication between the EC200S mobile communication unit and the external communication equipment, and makes the EC200S mobile communication unit enter normal working mode; for example, after enabling the power management device to power the EC200S mobile communication module through the MS51 power management unit, the EC200S mobile communication module can receive the animal pictures transmitted by the A40I minimum system and transmit the animal pictures to the external communication equipment, so that the external communication equipment can understand the working state of the energy-saving system;

[0066] It can be understood that, through the above steps, the MS51 power management unit sequentially sends the first enable signal, the second enable signal and the third enable signal, so as to respectively control the A40I minimum system, the camera device and the EC200S mobile communication unit to enter the normal working mode, not only achieving the purpose of the camera device shooting and transmitting animal pictures, but also transmitting the animal pictures to the external communication device through the EC200S mobile communication module, so that the external communication device can understand the working state of the energy-saving system, and because the MS51 power management unit sequentially sends the first enable signal, the second enable signal and the third enable signal, the load of the field monitoring device (i.e. the energy-saving system) changes smoothly in the case of power failure, solving the problem that the field monitoring device often appears power failure due to the complex and changeable environment in the field, the load changes instantaneously in the moment of power failure, resulting in the non-monotonicity of the power-off waveform, and prolonging the service life of the rechargeable battery.

[0067] In step S105, when it is detected that the infrared signal exceeds the preset value, the A40I minimum system is caused to send the power saving signal; wherein the preset value is set according to user demand, which is not specifically limited here.

[0068] In step S106, when the camera device receives the power saving signal, the transmission of the animal pictures is stopped, and the animal pictures are stored in the local storage unit of the camera device, so that the electric energy is saved.

[0069] Through the above steps S101 to S106, in the embodiment, firstly, when the rechargeable battery completes charging and starts discharging, after the MS51 power management obtains the discharging voltage, the MS51 power management unit sequentially sends the first enable signal, the second enable signal and the third enable signal to respectively control the A40I minimum system, the camera device and the EC200S mobile communication unit to enter the normal working mode, not only achieving the purpose of the camera device shooting and transmitting animal pictures, but also transmitting the animal pictures to the external communication device through the EC200S mobile communication module, so that the external communication device can understand the working state of the energy-saving system, and because the MS51 power management unit sequentially sends the first enable signal, the second enable signal and the third enable signal, the load of the field monitoring device (i.e. the energy-saving system) changes smoothly in the case of power failure, solving the problem that the field monitoring device often appears power failure due to the complex and changeable environment in the field, the load changes instantaneously in the moment of power failure, resulting in the non-monotonicity of the power-off waveform, and prolonging the service life of the rechargeable battery, and then, when it is detected that the infrared signal exceeds the preset value, the A40I minimum system is caused to send the power saving signal to control the camera device to stop transmitting the animal pictures, and store the animal pictures in the local storage unit of the camera device, so that the electric energy is saved, and the problem of short service life of the field monitoring device in the related art is solved.

[0070] Figure 2 is a first circuit function module schematic diagram of the energy-saving system according to the embodiment of the application, as shown in Figure 2 In order to prolong the service life of the rechargeable battery, in some embodiments, when the camera device receives the power saving signal, the transmission of the animal pictures is stopped, and the animal pictures are stored in the local storage unit of the camera device, and the method further comprises the following steps:

[0071] The MS51 power management unit receives the power saving signal and sends a first disable control signal;

[0072] The power management device receives the first disable control signal, stops supplying power to the A40I minimum system, and makes the A40I minimum system stop normal work, so that the system enters the power saving mode, thereby saving power. It is worth noting that in the power saving mode, the camera device can still take animal pictures and store the animal pictures in the local storage unit, but cannot transmit the animal pictures.

[0073] The EC200S mobile communication unit receives the first disable control signal and sends a heartbeat signal to the MS51 power management unit at a fixed time interval, wherein the fixed time is set according to user demand, which is not limited here.

[0074] In some embodiments, in order to save power, after the EC200S mobile communication unit receives the first disable control signal and sends a heartbeat signal to the MS51 power management unit at a fixed time interval, the method further comprises the following steps:

[0075] When the EC200S mobile communication unit receives a sleep instruction, a sleep signal is sent, wherein the sleep instruction is a sleep instruction sent by the server communication module through a communication base station; Figure 3 is a schematic diagram of the EC200S mobile communication unit communicating with an external communication device according to the embodiment of the application, as shown in Figure 3 The server communication module and the EC200S mobile communication unit respectively communicate through a base station;

[0076] When the MS51 power management unit receives the sleep signal, a second disable signal is sent;

[0077] When the power management device receives the second disable signal, the power supply to the camera device is stopped, so that the camera device stops taking animal pictures. At this time, the camera device cannot take or transmit animal pictures. At this time, the system enters the sleep working mode, thereby reducing the overall power consumption of the system.

[0078] It is noted that the MS51 power management unit and the EC200S mobile communication unit maintain normal communication whether working in the power saving mode or the sleep mode.

[0079] In some field application scenarios, animal activities are more frequent. In order to be able to take photos of animals, in some embodiments, after the power management device receives the second disable signal and stops supplying power to the camera equipment, the method further includes the following steps:

[0080] When the EC200S mobile communication unit receives the wake-up instruction, a wake-up signal is sent, wherein the wake-up instruction is a sleep instruction sent by the server communication module through a communication base station.

[0081] When the MS51 power management unit receives the wake-up signal, the first enable signal and the second enable signal are re-sent, so as to enable the charge-discharge management device to supply power to the A40I minimum system, enable the power management device to supply power to the camera equipment to enter the normal working mode, and also enable the A40I minimum system and the EC200S mobile communication module to supply power to enter the normal working mode, so as to realize the sleep mode entering the normal working mode.

[0082] In order to prevent the program from running away and causing the system to be unable to work normally, in some embodiments, after the EC200S mobile communication unit receives the first disable control signal and sends a heartbeat signal to the MS51 power management unit at a fixed time interval, the method further includes the following steps:

[0083] In the case where the EC200S mobile communication unit stores an execution program, when the EC200S mobile communication unit detects that the execution program has an exception, the heartbeat signal sent to the MS51 power management unit is stopped, wherein the MS51 power management unit includes a built-in watchdog circuit; since those skilled in the art know the working principle of the built-in watchdog circuit, it is not described here.

[0084] When the MS51 power management unit does not monitor the heartbeat signal within a preset time, the built-in watchdog circuit is controlled to wake up by itself, so that the MS51 power management unit re-sends the first enable signal, the second enable signal and the third enable signal, i.e. the MS51 power management first enables the charge-discharge management device to supply power to the A40I minimum system to enter the normal working mode, then the MS51 power management second enables the power management device to supply power to the camera equipment to enter the normal working mode, and finally the MS51 power management third enables the power management device to supply power to the EC200S mobile communication module to enter the normal working mode. In this embodiment, the foolproof function is realized through the above steps to prevent the program from running away and causing the system to be unable to work normally. In this way, even if it enters an unknown state mode, it can also be re-awakened and work normally.

[0085] In some embodiments, when the rechargeable battery is completed charging and starts discharging, before the discharging voltage is obtained, the method further comprises the following steps:

[0086] The charging voltage is obtained, wherein the charging voltage is greater than the discharging voltage; in this embodiment, the charging voltage is 5V which is greater than the discharging voltage 3.3V;

[0087] The charging voltage is input into the charge-discharge management device to obtain a charging current in a preset range, and the rechargeable battery is charged based on the charging current;

[0088] The MS51 power management unit is started based on the charging voltage;

[0089] After the MS51 power management unit is started, a first enable signal is sent to control the charge-discharge management device to supply power to the A40I minimum system, wherein a backflow prevention protection circuit and a voltage reduction chip are arranged between the power supply end of the charging voltage and the MS51 power management unit;

[0090] A second enable signal is sent to control the power management device to supply power to the camera equipment;

[0091] A third enable signal is sent to control the voltage stabilizing chip to supply power to the EC200S mobile communication unit.

[0092] Specifically, referring to Figure 2 During the charging process, the mechanical switch is in a normally closed state, the 5V charging power supply is input and passes through the charge-discharge management device to charge the battery and manage the charging current; at the same time, the 5V charging power supply passes through the backflow prevention protection circuit to power up the MS51 power management system to start the MS51 power management system; the MS51 power management unit enables the charge-discharge management device to supply power to the A40I minimum system to enter the normal working mode in the first step, then the MS51 power management unit enables the power management device to supply power to the camera equipment to enter the normal working mode in the second step, and then the MS51 power management unit enables the power management device to supply power to the EC200S mobile communication module to enter the normal working mode in the third step.

[0093] In one example, the backflow prevention protection circuit is an ideal diode.
