Current Problems existing: no matter adopt any starting control mode, the semaphore gathered is all many, the parts producer involved is also many, need to gather ignition key signal, starter relay signal, generator neutral point signal (or engine rotational speed signal), then controlled the work of starter relay, starting power supply main switch by front and back sequential.Controlling component is more, participates in signal more, and control logic is complicated, once break down, does not have word-information display, and maintenance is complicated, not easily checks reason; Simultaneously; prior art electromagnetic power-supply general switch powers on to the main power line of starter motor always; this line is long, and line is also relatively thicker, and installation position is near engine in situ vehicle frame; in driving conditions, vibration is large; easy friction, because starting current is too large, not easily arranges safety plate; the short-circuit protection of this circuit is difficult to solve always, is an industry difficult problem.
Model utility content
It is more to there is controlling component for prior art in the utility model, participates in signal more, and control logic is complicated, once break down, does not have word-information display, and maintenance is complicated, not easily checks reason; Simultaneously; prior art electromagnetic power-supply general switch powers on to the main power line of starter motor always, and this line is long, and line is also thicker; installation position is near engine in situ vehicle frame; in driving conditions, vibration is large, easily rubs, because starting current is too large; not easily safety plate is set; the short-circuit protection of this circuit is difficult to solve always, is the problem of an industry difficult problem, proposes a kind of startup control circuit device with protective gear.
The technical solution of the utility model is: a kind of startup control circuit device with protective gear, comprise storage battery, storage battery is connected with starter motor with electromagnetic power-supply general switch through manual main switch, starter motor connects 24V power supply through starting relay, starter motor guide line is connected with 24V power supply with key STARTA gear through motor ECM, a branch road of electromagnetic power-supply general switch is connected with 24V power supply through general power rocker switch, electric current and temperature-detecting device is serially connected with between described electromagnetic power-supply general switch and general power rocker switch, electric current and temperature-detecting device through wire be arranged on manual main switch and be connected with the CMS power detector on circuit between electromagnetic power-supply general switch, electric current and temperature-detecting device are provided with CAN interface.
The described startup control circuit device with protective gear; circuit between described electromagnetic power-supply general switch and starter motor is serially connected with starter motor main switch; a branch road of starter motor main switch and electric current and temperature-detecting device; the shell of starter motor is connected with shell bonding, the negative terminal of storage battery is connected with bonding.
The described startup control circuit device with protective gear, 24V power supply and key START keep off, 24V power supply and starting relay, be provided with safety fuse cutout between 24V power supply and general power rocker switch.
The beneficial effects of the utility model are: 1, the utility model is by CAN signal, whether power on according to the working state control starter motor main power line of motor ECM completely, control precisely, not easy break-down, starter motor main power line only has electricity when needs start, all the other times are not charged, improve the fire savety of vehicle line.In addition, detect electric current when starting and the electric current of car load by lasting, can auto-breaking when electric current is excessive, after failture evacuation, re-power, battery main switch again can normally adhesive work, is equivalent to serve the effect that big current can recover insurance.
2, whether connect by controlling starter motor main power line with motor CAN communication; control principle is simple; do not need other unnecessary control apparatus; reliable operation; easy to maintenance, only need maintenance two communications, in addition; rear block terminal there are normal work indicator light and overcurrent protection work indicator light, facilitate fault diagnosis.

Embodiment
Embodiment 1: composition graphs 1-Fig. 2, a kind of startup control circuit device with protective gear, comprise storage battery, storage battery is connected with starter motor with electromagnetic power-supply general switch through manual main switch, starter motor connects 24V power supply through starting relay, starter motor guide line is connected with 24V power supply with key STARTA gear through motor ECM, a branch road of electromagnetic power-supply general switch is connected with 24V power supply through general power rocker switch, electric current and temperature-detecting device is serially connected with between described electromagnetic power-supply general switch and general power rocker switch, electric current and temperature-detecting device through wire be arranged on manual main switch and be connected with the CMS power detector on circuit between electromagnetic power-supply general switch, electric current and temperature-detecting device are provided with CAN interface.Circuit between described electromagnetic power-supply general switch and starter motor is serially connected with starter motor main switch, a branch road of starter motor main switch is connected with electric current and temperature-detecting device.The shell of starter motor is connected with shell bonding, the shell of storage battery is connected with bonding.24V power supply and key START keep off, 24V power supply and starting relay, be provided with safety fuse cutout between 24V power supply and general power rocker switch.
Working principle: open general power rocker switch, electromagnetic power-supply general switch adhesive is connected, full car powers on, rotate key and keep off-ACC gear-ON gear-START gear from OFF, when ON keeps off, motor ECM powers on and starts working, when motor ECM receives the bootwait order that key sends, ECM can send starting ready signal in CAN, now, send control command after the CAN module (electric current and temperature detecting module) be built in rear block terminal receives the starting ready signal of motor and connect starter motor main switch, after getting to START gear, motor ECM controls starter relay adhesive, starter motor entry into service, when after engine start, motor ECM can send the signal that vehicle launch completes, now, be built in the electric current in rear block terminal and temperature detecting module cut-out starter motor main switch, the power-off of whole starter motor mair motor.As can be seen from above control logic, the main power line of starter motor only has electricity in the process of accurately starting and starter motor running, and remaining time does not have electricity, can reduce the probability of starter motor main power line short-circuit fire like this.In addition; in starting process or in running process, if starting current is excessive or total current is excessive, or temperature is too high; be built in electric current in rear block terminal and temperature detecting module all can cut off electromagnetic power-supply general switch, start the object of car load power-off protection.
