In order to solve the technical problem of high power consumption of existing solar lamps during storage or standby, the present invention provides a wake-up and sleep circuit of a Hall switch.

In one embodiment, as shown in FIGS. 1 and 2 , the Hall switch wake-up and sleep circuit includes a controlled circuit 105 , a Hall switch 103 , a magnetic element 101 and a single-chip microcomputer 104 .

Wherein, the Hall switch 103 senses the magnetic induction intensity of the magnetic member 101, and when the magnetic induction intensity reaches a preset magnetic intensity value, outputs a first level signal, and when the magnetic induction intensity is lower than a preset magnetic intensity value, outputs a second level signal Signal. At this time, the preset magnetic intensity value of the magnetic induction is determined according to the type of the Hall switch 103 , and when the Hall switch 103 is lower than or higher than the preset magnetic intensity value, the Hall switch 103 flips. In this embodiment, if the Hall switch 103 senses that the magnetic induction intensity of the magnetic member 101 is equal to the preset magnetic intensity value, the first level signal is output. Optionally, the first level signal is at a low level at this time, When the single-chip microcomputer 104 receives the first level signal output by the Hall switch 103, it controls the controlled circuit 105 to sleep. At this time, no power-consuming equipment is running in the entire system, so that the wake-up and sleep circuits of the entire Hall switch do not have any power. path, so there is no loss of current. If the Hall switch 103 senses that the magnetic induction intensity of the magnetic member 101 is lower than the preset magnetic intensity value, the output second level signal, when the single chip microcomputer 104 receives the second level signal output by the Hall switch 103, the control is controlled. The control circuit 105 works, and the circuit is turned on at this time. Optionally, the second level signal is at low level at this moment. It is worth noting that there will be a transportation process from the completion of the manufacture of various electrical appliances to the installation, because the electrical appliances will undergo various tests when they leave the factory, and each electrical appliance will have a battery, either for powering the dormant circuit or for powering the battery. The entire electric appliance is powered, and these batteries are charged during the field test, and then the performance is tested. Finally, it leaves the factory and is transported to the purpose of installation. During this transportation process, the circuit where the battery is located will always supply power to the dormant circuit, so that it will be discharged with low power, so that the power of the battery will gradually decrease, and finally the remaining power of the battery may not be enough to support dormancy. The work of the circuit, thus affecting the accuracy and reliability of the subsequent installation. Especially after the battery output is completed or when there is an external current, it may cause irreversible damage to the battery or the entire electrical appliance.

In this embodiment, the charging power supply is a solar panel, so the real-time charging power supply voltage is the voltage converted by the solar panel at this time, that is, the light-controlled voltage. The light control voltage is compared with the voltage of the storage battery. When the light control voltage is greater than the voltage of the storage battery, the single chip microcomputer 104 outputs the third control signal, and the discharge circuit disconnects the path between the storage battery and the electrical appliance after receiving the third control signal, that is, The battery stops discharging. When the light control voltage is lower than the voltage of the storage battery, the single chip microcomputer 104 outputs the fourth control signal. After receiving the fourth control signal, the discharge circuit conducts the path between the storage battery and the electrical consumer, that is, the storage battery starts to discharge. In this embodiment, by comparing the voltage of the storage battery with the charging power source, the discharge state of the storage battery can be controlled to realize the function of self-regulation without additional control circuit or manual control. Used in solar energy systems, comparing the photo-control voltage of the solar panel with the voltage of the battery can not only realize the intelligent charging and discharging of the battery, but also judge whether the external environment is daytime (light) or night (night) based on the voltage.
