Embodiment Construction

[0032] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0033] In this embodiment, the combined instrument is based on (attached figure 1 ) from the voltage collected by the voltage divider circuit and the resistance value assigned in the voltage divider circuit, calculate the actual voltage value, and receive the engine speed signal at the same time, and then light the alarm, Make an alarm sound, or even cut off the power supply of some electrical appliances. When the combination meter detects that the voltage of the battery is lower than the alarm value M, the control alarm light will flash and the buzzer will be driven to sound. When it is detected that the voltage is lower than the dangerous value L, the power supply of the high-power electrical appliance is cut off, and the buzzer with twice the frequency is driven to buzz.
