Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment; technical scheme in the utility model embodiment is clearly and completely described; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of band temperature control intelligent protection car emergency starts power supply, comprise lithium cell group, governor circuit and 12V/24V change-over circuit, lithium cell group is connected with governor circuit by reduction voltage circuit 14, the positive pole 4 of lithium cell group is directly connected with mouth wire clamp positive pole, the 0V tap 1 of battery pack and 12V tap 2 access two input ends of 12V/24V change-over circuit respectively, voltage identification circuit 9 one end is connected with black wire clamp, the other end is connected with the control end 3 of 12V/24V change-over circuit, the mouth of 12V/24V change-over circuit is connected with the source electrode 11 of metal-oxide-semiconductor, as the input end of black wire clamp, metal-oxide-semiconductor drain electrode 13 is connected with wire clamp negative pole, the grid of metal-oxide-semiconductor is connected with metal-oxide-semiconductor driving circuit, governor circuit and inverted connection detecting circuit 6, short-circuit detecting circuit 7, over-current detection circuit 8 is connected to form the security protection module of whole system.
Described governor circuit also connects OLED display circuit 10.
Principle of work of the present utility model is: when described wire clamp and automobile rectify negative pole reversal connection or red wire clamp sends corresponding spurious signal to governor circuit respectively with inverted connection detecting circuit 6 during the short circuit of black wire clamp and short-circuit detecting circuit 7; When starting automobile, electric current is excessive, and over-current detection circuit 8 sends over-current signal to governor circuit; The form of error result by code in OLED display circuit 10 that governor circuit is responsible for inverted connection detecting circuit 6, short-circuit detecting circuit 7 and over-current detection circuit 8 to send shows, warning misoperation, the grid 16 of metal-oxide-semiconductor is connected with metal-oxide-semiconductor driving circuit, when there is any fault or improper connection, governor circuit sends instruction allows metal-oxide-semiconductor driving circuit turn off metal-oxide-semiconductor, thus disconnects the connection between battery electrode and black wire clamp.
