Namely, after repeated conduction, the electronic price tag program is electrified again to work, and fault restart is realized, so that the problem of low efficiency caused by the fact that a user needs to disassemble the battery after the electronic price tag fault is solved, and the use experience of the user is improved.
As further shown in fig. 2, as an alternative implementation manner, in this embodiment, D4 is a battery connector of the valence button battery, the sensing element is a hall device S1, the first switching element is a PMOS transistor VT2, and the second switching element is an NMOS transistor Q1. In order to ensure the price tag power consumption, the hall device S1 can be selected as a low-power-consumption device, for example, a hall device with a normal static operating current of not more than 500nA is selected. The 1 pin of a battery connector D4 of the button battery is connected with the anode of the button battery, and the 2 pin of a battery connector D4 is connected with the cathode of the button battery. And a C11 voltage-stabilizing filter capacitor is arranged on the VBAT network of the button cell. The button cell VBAT network is connected to the source electrode of the PMOS tube VT2, a resistor R2 is connected in parallel between the control electrode of the PMOS tube VT2 and the source electrode of the PMOS tube VT2, the control electrode of the PMOS tube VT2 is connected with a C3 capacitor, the drain electrode output power of the PMOS tube VT2 is VBAT _ ESL, and the VBAT _ ESL is the power supply of the electronic price tag. The button cell VBAT network is connected to a power Supply pin Supply of the Hall device S1, an output pin OUT of the Hall device S1 is connected to the button cell VBAT network through a pull-up resistor R3 and is connected to a control electrode of an NMOS tube Q1, a source electrode of the NMOS tube Q1 is connected to GND, and a drain electrode of the NMOS tube Q1 is connected to a control electrode of a PMOS tube VT 2.
The working process is as follows:
when the price tag battery connector is connected with a button battery, the Hall device S1 starts to work, when a nonmagnetic object such as a magnet approaches, the output of the output signal pin OUT of the Hall device S1 is high level by default, namely the control level of the NMOS transistor Q1 is high level, and when the control level of the NMOS transistor Q1 is high level, the NMOS transistor Q1 works in a switch conducting state, namely the drain of the NMOS transistor Q1 is conducted to be low level. When the drain of the NMOS transistor Q1 becomes low level, that is, the control voltage of the PMOS transistor VT2 is low level, and when the control voltage of the PMOS transistor VT2 is low level, the PMOS transistor VT2 works in the on-off state, that is, the button cell VBAT network is output to VBAT _ ESL through the PMOS transistor VT2 to supply power to the total power supply of the price tag, and the electronic price tag is normally powered up and works.
When the price tag is in a fault state such as a dead halt state, the price tag main power supply VBAT _ ESL needs to be powered off to achieve the purpose of power-off restarting, at the moment, the magnet is close to the Hall device S1 of the price tag, and when the price tag Hall device S1 senses that the magnet is close, the output of the output signal pin OUT of the Hall device S1 becomes a low level. That is, the control voltage of the NMOS transistor Q1 is low, when the control voltage of the NMOS transistor Q1 is low, the NMOS transistor Q1 operates in the off state, and the drain of the NMOS transistor Q1 is pulled to high by the pull-up resistor R2. When the drain of the NMOS transistor Q1 goes high, i.e. the control voltage of the PMOS transistor VT2 goes high, and when the control voltage of the PMOS transistor VT2 goes high, the PMOS transistor VT2 operates in the off state. Namely, the PMOS tube VT2 cuts off the VBAT network of the button cell to supply power to the price tag main power supply VBAT _ ESL. When the magnet is removed, the output signal pin OUT of the Hall device S1 is changed into high level, the PMOS tube VT2 works in a switch conducting state, namely, the button cell VBAT network is output to VBAT _ SEL through the PMOS tube VT2 to supply power to the total power supply of the price tag, and the price tag is electrified again to work.
In summary, the electronic price tag start control method provided by the embodiment of the invention can realize the abnormal state restart function in the non-disassembly state, and the price tag fault state power-off restart can be realized by the sensing element receiving the target sensing signal, so that the working efficiency is improved, and the convenience of the after-sale analysis problem is improved.
