The invention provides a wake-up and sleep circuit of a Hall switch, which aims to solve the technical problem that the power consumption of the existing solar lamp is high when the solar lamp is stored or is in standby.
In one embodiment, as shown in fig. 1 and 2, the wake-up and sleep circuit of the hall switch includes a controlled circuit 105, a hall switch 103, a magnetic element 101, and a single-chip microcomputer 104. The power input end of the Hall switch 103 is connected with a power supply, and the signal output end of the Hall switch 103 is connected with the signal input end of the singlechip 104; the signal output end of the singlechip 104 is connected with a controlled circuit 105.
The hall switch 103 senses the magnetic induction intensity of the magnetic member 101, and outputs a first level signal when the magnetic induction intensity reaches a preset magnetic intensity value, and outputs a second level signal when the magnetic induction intensity is lower than the preset magnetic intensity value. At this time, the preset magnetic intensity value of the magnetic induction intensity is determined according to the type of the hall switch 103, and the hall switch 103 is turned over when the hall switch 103 is lower than or higher than the preset magnetic intensity value. In this embodiment, if the hall switch 103 senses that the magnetic induction intensity of the magnetic element 101 is equal to the preset magnetic intensity value, a first level signal is output, optionally, the first level signal is at a low level at this time, and the singlechip 104 controls the controlled circuit 105 to sleep when receiving the first level signal output by the hall switch 103, and at this time, no power consumption device in the whole system is running, so that the wake-up and sleep circuit of the whole hall switch has no path, and no current loss occurs. If the hall switch 103 senses that the magnetic induction intensity of the magnetic piece 101 is lower than the preset magnetic intensity value, the output second level signal, and the singlechip 104 controls the controlled circuit 105 to work when receiving the second level signal output by the hall switch 103, and the circuit is turned on. Alternatively, the second level signal is low at this time. It is noted that the electrical appliances are subjected to a transportation process from the completion of their manufacture to their installation, because they are tested when shipped from the factory, and each electrical appliance has a battery, either for powering a sleep circuit or for powering the entire electrical appliance, which is charged during the off-site test, and then tested for performance. And finally, leaving the factory and transporting the storage battery to an installation destination, wherein in the transportation process, the circuit where the storage battery is positioned supplies power to the dormant circuit all the time, so that the power of the storage battery is gradually reduced, and finally, the residual power of the storage battery is possibly insufficient to support the work of the dormant circuit, thereby influencing the accuracy and the reliability of subsequent installation. In particular, after the electric quantity of the storage battery is output or when external current acts, irreversible damage can be caused to the storage battery or the whole electric appliance. The technical scheme in this embodiment can make the wake-up and sleep circuit of the hall switch not need to preset a signal receiving circuit, that is, no extra sleep power supply is required to be set to accept external, wake-up and sleep signals during sleep, in addition, the hall switch 103 is set to disconnect the circuit under the action of the magnetic element 101, so that external current or current possibly flowing through an electric appliance cannot pass through an induced magnetic field or an induced electric field, thereby affecting the sleep state and the wake-up state of the wake-up and sleep circuit of the hall switch, better isolating external interference, more reliably realizing zero-power sleep.
Optionally, as shown in fig. 3, the controlled circuit 105 includes a sampling circuit and a charging circuit, the charging circuit has an input end, an output end and a controlled end, the input end of the charging circuit is used for being connected with a charging power supply, the output end of the charging circuit is used for being connected with a storage battery, and the controlled end of the charging circuit is connected with the singlechip 104; the input end of the sampling circuit is connected with the storage battery, and the output end of the sampling circuit is connected with the singlechip 104.
When the sampling circuit works, the voltage of the storage battery is detected and output to the singlechip 104. The singlechip 104 outputs a first control signal or a second control signal according to the voltage of the storage battery detected by the sampling circuit, controls the charging circuit to work or sleep, at this time, compares the collected voltage of the storage battery with the real-time charging power supply voltage, in this embodiment, optionally, the charging power supply is a solar panel, so that the real-time charging power supply voltage is the voltage converted by the solar panel during this time, namely, the light-operated voltage is compared with the voltage of the storage battery, when the light-operated voltage is greater than the voltage of the storage battery, the singlechip 104 outputs the first control signal, and after receiving the first control signal, the charging circuit conducts a path between the charging power supply and the storage battery, namely, the solar panel starts charging the storage battery. When the photo-controlled voltage is lower than the voltage of the storage battery, the singlechip 104 outputs a second control signal, and the charging circuit cuts off a passage between the charging power supply and the storage battery after receiving the second control signal, so that the charging of the storage battery is stopped. In this embodiment, the state of charge of the battery can be controlled by detecting the battery voltage versus the charging source to achieve a self-regulating function without additional control circuitry or manual control. The intelligent charging device is used for comparing the light-operated voltage of the solar panel with the voltage of the storage battery, not only can realize intelligent charging of the storage battery, but also can judge whether the external environment is in daytime (bright) or in dark (dark) according to the voltage, and the light-operated voltage of the solar panel can be higher than the voltage of the storage battery during the daytime to charge the storage battery, so that the intelligent charging of the storage battery is realized, the solar panel is convenient for recycling, and the intelligent charging device has a stronger self-regulating function.

The singlechip 104 outputs a third control signal or a fourth control signal according to the voltage of the storage battery detected by the sampling circuit, and controls the discharge circuit to work or sleep. At this time, the collected voltage of the storage battery is compared with the voltage of the real-time charging power supply, in this embodiment, the charging power supply is a solar panel, so the voltage converted by the solar panel is the voltage converted by the real-time charging power supply, namely, the photo-control voltage is compared with the voltage of the storage battery, when the photo-control voltage is greater than the voltage of the storage battery, the singlechip 104 outputs a third control signal, and the discharging circuit cuts off the path between the storage battery and the electric appliance after receiving the third control signal, namely, the storage battery stops discharging. When the light-operated voltage is lower than the voltage of the storage battery, the singlechip 104 outputs a fourth control signal, and the discharging circuit conducts the passage between the storage battery and the electric appliance after receiving the fourth control signal, namely, the storage battery starts to discharge. In this embodiment, the discharge state of the battery can be controlled by detecting the battery voltage to be compared with the charging power source, so as to realize the self-adjusting function without additional control circuit or manual control. The intelligent charging and discharging device is used for comparing the light-operated voltage of the solar panel with the voltage of the storage battery in a solar system, not only can realize intelligent charging and discharging of the storage battery, but also can judge whether the external environment is in daytime (bright) or in dark (dark) according to the voltage, the light-operated voltage of the solar panel can be higher than the voltage of the storage battery during daytime to charge the storage battery, and the light-operated voltage of the solar panel can be lower than the voltage of the storage battery during evening to discharge the storage battery. Thereby realizing the intelligent charge and discharge of the storage battery and facilitating the recycling of the solar energy system.
