An automobile electricity prevention and control computer, comprising a prevention and control computer and a prevention and control computer body. A conductive sheet is provided inside the prevention and control computer body. The conductive sheet is in close contact with a positive terminal head of a storage battery of a chuck, so that the current at a positive electrode of the storage battery flows through a relay or a thyristor of which the turning on and off is controlled by the prevention and control computer and then is output by an output terminal head on top. The prevention and control computer comprises a central control unit and a remote controller. A signal input end of the central control unit is connected to a signal output end of a signal receiving module of the remote controller. The relay or the thyristor is connected in parallel with an electricity control device, so that the current at the positive electrode of the storage battery also flows through the electricity control device of which the turning on and off is controlled by the prevention and control computer. The signal output end of the central control unit is connected to the signal input end of the electricity control device and the signal input end of the relay or the thyristor. The current input of the electricity control device and the relay or the thyristor is input from an output current at the positive electrode of an automobile battery after flowing through a detection and comparison circuit. By connecting an electricity control device in parallel with a relay of an original structure, it is achieved that when an automobile circuit is short-circuited or consumes electricity with a large current, a single-chip microcomputer controls the relay to be disconnected, and the current can only pass through the electricity control device. The electricity control device is connected in parallel with multiple circuits including a resistor and an auto-recover safety element, and therefore the electricity control device only allows the current not exceeding a predetermined value of the auto-recover safety element to pass though. |
