Accompanying drawing explanation
Fig. 1 is the electric circuit constitute block diagram of the utility model embodiment.
Fig. 2 is the electric circuit constitute schematic diagram of the utility model embodiment.
Embodiment
Referring to Fig. 1, the utility model embodiment is provided with sound light alarming circuit 1, error-polarity connection testing circuit 2, protection control circuit 3, direct current cabinet 4 and electric battery 5; Described sound light alarming circuit 1, error-polarity connection testing circuit 2, protection control circuit 3 are connected successively, the input termination electric battery of the input end of sound light alarming circuit 1 and error-polarity connection testing circuit 2, the output termination direct current cabinet of protection control circuit 3; Described sound light alarming circuit is provided with hummer and light emitting diode; the output terminal of the input termination error-polarity connection testing circuit 2 of hummer and light emitting diode; error-polarity connection testing circuit 2 is provided with isolation optocoupler and control device, and protection control circuit 3 is provided with relay and contactor.
As shown in Figure 2, the utility model embodiment is detected the positive and negative situation of battery polar by error-polarity connection testing circuit 2, hummer BUZ1 and the LED 1 of sound light alarming circuit 1 controlled in one end, realizes and reporting to the police, other end pilot relay, contactor disconnect, and realize intelligence anti-reverse.
In the time that battery polar is correct, BAT+ voltage makes 1,2 pin forward drive of integrated circuit (IC) 1 and makes 3,4 pin conductings of integrated circuit (IC) 1 in low resistive state through diode D1 → resistance R 1 → integrated circuit (IC) 1, thereby by the adhesive of relay R LY1 coil electricity, make 1, the 2 contact conductings of relay R LY1; Be the coil electricity of contactor KM1, the main contacts conducting that makes contactor KM1 is that battery can be powered to direct current cabinet; Due to diode D1 conducting, hummer BUZ1 and LED 1 all can not be lighted.
In the time of battery polar reversal connection, the actual positive voltage of battery is through BAT-end → diode D2 → resistance R 1 → hummer BUZ1 → LED 1, make hummer BUZ1 and LED 1 pilot lamp forward drive, pipe alarm and LED 1 pilot lamp of hummer BUZ1 lighted; Due to diode D2 conducting, integrated circuit (IC) 1 can not forward drive causes the relay R LY1 coil losing electricity can not adhesive, contactor KM1 contact is disconnected from direct current cabinet and disconnect, reverse connecting protection.
In the time that cell voltage is too low or do not connect, integrated circuit (IC) 1 cannot normally be worked, and causes the relay R LY1 can not adhesive, thereby contactor KM1 contact disconnects and also throwing off with direct current cabinet.
The utility model can also be realized the anti-error-polarity connection control of various logic; can not damage electric battery, direct current cabinet equipment as first connect correctly the situations such as reversal connection again; therefore more traditional control circuit has more intelligent; and control circuit is simple and reliable, and just can realize audible and visual alarm and anti-polarity protection without other accessory power supply.
(1) in the time that battery polar is correct, this pick-up unit pilot relay RLY1 adhesive; Thereby carry out the coil electricity of control contactor KM1, connect main battery loop and power to direct current cabinet through isolating diode (can cancel short circuit substitutes); Also can cancel relay and directly drive contactor control coil with triode Q1.
(2) above circuit can increase some anti-interference resistance capacitance and fly-wheel diodes in actual applications, is all to belong to rights and interests protection domain.
(3) contactor can be that the similar products such as relay substitute; Triode Q1 can be that the similar circuit such as metal-oxide-semiconductor or IGBT substitutes, and identical method is all to belong to rights and interests protection domain.
(4) electric battery can be the direct voltage source of other type, and direct current cabinet can be the DC load of other type.
