[0019] like Figure 1 As shown, the main system is responsible for the entire center control of the product. The main intelligent management systems include the display system, backlight drive system, and voice system. The main system management reads the power (voltage) value of the lithium battery from the input end of the functional power supply, and performs intelligent control of the system through the changing state of the power value. When the lithium battery power is as low as DC 7.2V, the main system starts intelligent power consumption management. When the lithium battery power is equal to or less than DC 7.2V, the display automatically recognizes that the display is needed according to the user's operating system, and then turns on the working state of the display. When the display function is not needed, it will be turned off, thereby reducing power consumption. The circuit principle of the display module is as follows Figure 2 As shown, the lithium battery power enters the 13th pin of U2 through R4, R5, and C9. When the lithium battery power is equal to or less than DC 7.2V, the main chip U2 cooperates with the system software to obtain a number. After the software determines, the 56th pin of the main chip U2 outputs a high level, and a power control circuit is formed through R4, R5, and OQ1 to stop the power output of OQ1. At this time, the display function of the display will be turned off, thereby reducing power consumption.

[0020] In some embodiments, when the power level of the lithium battery is lower than a first preset value and the user performs a display operation, the display screen is turned on.

[0021] In some embodiments, the backlight module includes twelve LED light emitting diodes, and the operating current of each LED light emitting diode is 20mA.

[0022] Backlight module circuit principle Figure 3 As shown, the lithium battery power enters the 13th pin of U2 through R4, R5, and C9. When the lithium battery power is equal to or less than DC 7.2V, the main chip U2 cooperates with the system software to obtain a number. After the software determines, the output levels of the 7th, 10th, 25th, 26th, 41st, 42nd, 43rd, 53rd, 54th, 64th, 66th, and 67th pins of the main chip U2 are low. At this time, the backlight system is controlled according to the user operation. In order to avoid the password being peeped, the 12 LED full display is intelligently controlled to work together with 6, which reduces the working power consumption and prevents the password from being peeped.

[0023] In some embodiments, the first preset number is six.

[0024] In some embodiments, when the power of the lithium battery is greater than the third preset value, the operating current of the voice module is greater than 200mA; when the power of the lithium battery is lower than the tenth preset value, the operating current of the voice module is lower than 30mA.

[0025] In some embodiments, the first preset value, the second preset value, the third preset value and the fifth preset value are 7.2V; the fourth preset value is 7.0V.

[0026] The circuit principle of the voice module is as follows Figure 4 As shown, the lithium battery power enters the 13th pin of U2 through R4, R5, and C9. When the lithium battery power is equal to or less than DC 7.2V, the main chip U2 cooperates with the system software to obtain a number. After the software determines, the 14th pin of the main chip U2 will adjust the voice volume of the voice system according to the battery power alarm status. The lower the power, the lower the volume. When the voltage is lower than DC 7.0V, the volume is reduced to the minimum, and the working current is less than 30mA.

[0027] The circuit principle of the electronic cat eye module is as follows Figure 5 As shown, the lithium battery power enters the 13th pin of U2 through R4, R5, and C9. When the lithium battery power is equal to or less than DC 7.2V, the main chip U2 cooperates with the system software to obtain a number. After the software determines, the 2nd and 3rd pins of the main chip U2 and the 2nd and 3rd pins of MU2 perform data transmission and communication. The electronic cat eye system controlled by MU2 through pins 11 and 12 will not be started.
