[0073] (i) The microprocessor U1 performs the following processing:

[0074] 1) The microprocessor U1 determines whether the bioelectric circuit B and the external load form a closed current loop, wherein the external load is the human body F or a conductor; the microprocessor U1 determines the voltage value of the PT 3.4 terminal, i.e., the pin 13:

[0075] (1.1) When the voltage value of PT 3.4 is ≥ 1 / 2 of the power supply voltage VDD, the microprocessor U1 determines that no external load is connected between the stainless steel buckle 3 and the shell 2, that is, at least one of the stainless steel buckle 3 and the shell 2 is not in contact with the external load, and the bioelectric circuit B does not form a closed current loop with the external load. At this time, the microprocessor U1 enters a low-power sleep state after a delay of 2S to save battery power. At the same time, the microprocessor U1 turns off PT 1.0, i.e., pin 7, and PT 3.5, i.e., pin 8, so that the finger sensing circuit is not conducting, and the first light-emitting diode G in the function display circuit is not conducting, i.e., it is not lit;

[0076] (1.2) When the voltage value of PT 3.4 is less than 1 / 3 of the power supply voltage VDD, the microprocessor U1 determines that an external load has been connected between the stainless steel buckle 3 and the shell 2, that is, the stainless steel buckle 3 and the shell 2 are in contact with the external load respectively, and the bioelectric circuit B forms a closed current loop with the external load, and the microprocessor U1 enters the normal working state, connects and starts to identify the voltage value fed back by the bioelectric current obtained by the PT 3.3 end, that is, pin 12 after passing through the external load; at the same time, the microprocessor U1 turns on PT 1.0, that is, pin 7, and PT 3.5, that is, pin 8, so that the finger sensing circuit E is turned on, so that the first light-emitting diode G in the function display circuit D is synchronously lit as the finger approaches the finger sensing metal sheet 18, or extinguished as the finger moves away from the finger sensing metal sheet 18;

[0077] 2) The microprocessor U1 determines whether the closed current loop formed by the bioelectric circuit B and the external load is a normal current value loop or a short circuit state according to the voltage value fed back by the bioelectric current obtained from the PT 3.3 terminal after passing through the external load;

[0078] (2.1) When the voltage value obtained from the PT 3.3 terminal is ≥1.3V, the microprocessor U1 determines that the closed current loop is in a short-circuit state, that is, the stainless steel hook 3 and the housing 2 are in short-circuit contact, then the microprocessor U1 will immediately shut off the output of PT5.0 and control PT 3.1, that is, pin 10 is intermittently connected to the ground inside the microprocessor U1, at this time, the second light-emitting diode R in the function display circuit D flashes red intermittently to give a warning; at the same time, the microprocessor U1 shuts off PT 1.0, that is, pin 7 and PT3.5, that is, pin 8, so that the finger sensing circuit is not conducting, and the first light-emitting diode G in the function display circuit is not conducting, that is, it is not lit;

[0079] (2.2) When the voltage value obtained from PT 3.3 is: 0.2V<voltage value≤1.2V, the microprocessor U1 determines that the wearer is wearing the device normally, that is, the bioelectric circuit B has formed a normal closed current loop with the human body F, and the microprocessor U1 maintains the PT5.0 output. At the same time, the microprocessor U1 connects PT 1.0, i.e., pin 7, and PT 3.5, i.e., pin 8, so that the finger sensing circuit E is turned on, and the first light-emitting diode G in the function display circuit D is synchronously lit as the finger approaches the finger sensing metal sheet 18, or is extinguished as the finger moves away from the finger sensing metal sheet 18; when the stainless steel buckle 3 and the stainless steel shell 2 are in contact with the human body at the same time, so that the bioelectric current forms a bioelectric current closed loop with the human body and acts on the human body, the current flowing through the human body ranges from 0.1μA to 8.0μA, as shown in FIG. Fig.21 shown.

[0080] (2.3) When the voltage of PT 3.3 is less than 0.2V, the microprocessor U1 determines that the external load is not connected, that is, the stainless steel buckle 3 and the housing 2 have been separated from the human body F. At this time, the microprocessor U1 enters a low-power sleep state to save battery power. At the same time, the microprocessor U1 turns off PT 1.0, i.e., pin 7, and PT 3.5, i.e., pin 8, so that the finger sensing circuit is not conducting, and the first light-emitting diode G in the function display circuit D is not conducting, i.e., it is not lit;

[0081] 3) The microprocessor U1 determines whether the battery needs to be charged according to the voltage value of the power supply voltage VDD; when the power supply voltage VDD is lower than 2.9V, the microprocessor U1 turns off the bioelectric circuit B by disconnecting the output of PT 5.0, i.e., pin 4, and the input of PT 3.3, i.e., pin 12 and PT3.4, i.e., pin 13, and turns off the finger sensing circuit E by disconnecting PT 1.0, i.e., pin 7 and PT 3.5, i.e., pin 8, so that the first light-emitting diode G in the function display circuit D is not turned on, i.e., not lit; at the same time, PT 3.1, i.e., pin 10 is intermittently turned on to ground for 400ms every 300ms inside the microprocessor U1, so that the second light-emitting diode R in the function display circuit D flashes to give a low voltage warning, prompting timely charging.

[0082] (ii) The finger sensing circuit E is used to detect whether the bioelectric circuit B and the human body F form a conductive current closed loop, and confirm whether they are in a normal usable state;

[0083] When the state output pin 3 of the finger sensing circuit is connected to PT 1.0, i.e., pin 7, of the microprocessor U1, and the distance between the finger and the finger sensing metal sheet 18 is ≥ 2 mm, the state output pin 3 of the touch sensing chip U2 is not connected to the ground inside the touch sensing chip U2, and PT 1.0 is pulled up to a high level by R1. The microprocessor U1 determines that the finger does not touch the finger sensing metal sheet 18 based on the high level of PT 1.0, and disconnects PT 3.5, i.e., pin 8, so that the first light-emitting diode G in the function display circuit is not turned on, that is, it is not lit;

[0084] When the distance between the finger and the finger sensing metal sheet 18 is less than 2 mm, the touch sensing chip U2 determines that the finger has approached the finger sensing metal sheet 18, and the state output pin 3 of the touch sensing chip U2 is connected to the ground inside the touch sensing chip U2, so that the PT 1.0 of the microprocessor U1, that is, the pin 7, changes from a high level to a low level. The microprocessor U1 confirms that the finger has touched the finger sensing metal sheet 18 according to the low level of PT 1.0. At this time, if the bioelectric circuit B is in a state of forming a normal bioelectric current closed loop with the human body, the PT 3.5 end of the microprocessor U1 is connected to the ground inside the microprocessor U1, so that the first light-emitting diode G in the function display circuit D is turned on and lights up, indicating that the bioelectric circuit B is in a state of forming a normal bioelectric current closed loop with the human body F;

[0085] If the bioelectric circuit B is in an abnormal bioelectric current closed loop without contact with the human body F or a state where no bioelectric current closed loop is formed without contact with the human body F, regardless of whether the finger is close to the finger sensing metal sheet 18, the PT 3.5 terminal, i.e., pin 8, of the microprocessor U1 is disconnected from the ground inside the microprocessor U1, so that the first light-emitting diode G in the function display circuit is not turned on, i.e., not lit, indicating that the bioelectric circuit B is in an abnormal bioelectric current closed loop without contact with the human body F or a state where no bioelectric current closed loop is formed without contact with the human body F.

[0086] The pendant blood pressure reducing heart protector of the present invention, when the stainless steel hanging buckle 3 and the shell 2 are in contact with the human body at the same time, the bioelectric current of the bioelectric circuit B on the circuit board 13 forms a bioelectric current closed loop with the human body and acts on the human body, and the current flowing through the human body ranges from 0.1uA to 8.0uA.
