Background technology
Mobile unit need to consume the electric energy of vehicle as an independent system platform (as the platform based on arm master chip), along with the increase to mobile unit functional requirement, the hardware of mobile unit configuration is (as external GPS, communication module) kind, quantity and performance constantly promote, and also bring larger energy consumption.Traditional vehicular platform is all to form based on the additional various external devices of a master chip (as arm chip), during work, the work of mobile unit is all to be controlled by master chip, according to the different scenes of vehicle, some external device does not need to use, can close with energy-conservation, under extreme case, only need wherein minority peripheral hardware work just can guarantee demand, and very simple to the control of these peripheral hardwares, if at this moment allow the larger master chip of energy consumption work because using these peripheral hardwares always, can additionally produce power consumption.
The mode of operation of onboard system generally depends on the state of vehicle own.For example, under driving states, the working state schematic representation of traditional mobile unit when driving.Vehicle need to obtain vehicle position information, needs the external GPS equipment work of onboard system, and vehicle need to be communicated by letter with the vehicle management center on network, needs the external communication module work of onboard system, and mode of operation as described in Figure 1.Master chip is mutual by bus and communication module, and controls the power supply of communication module.
Under dead ship condition, because vehicle is not activated, invariant position, at this moment can close the external GPS equipment of onboard system, if at this moment also needed, communicate by letter with vehicle management center, as long as open separately external communication module, other peripheral hardwares can be closed, at this moment in fact whole onboard system only has master chip and external communication module in work, i.e. state as shown in Figure 2, but in fact do not have at present corresponding energy-saving control method, under dead ship condition, for guaranteeing the normal work of communication module, will make master chip is still mode of operation, caused very large waste.Therefore, if can be for powerful device provides administration of energy conservation, thereby extend work-hours and the service life of mobile unit under certain electric weight, be highly significant.
Utility model content
The technical problems to be solved in the utility model, be to provide a kind of energy-saving control circuit of vehicular high-power equipment, can according to the state of vehicle own, control the mode of operation of corresponding powerful device, realize energy-saving scheme, also can extend the service life of some equipment.
The utility model is achieved in that a kind of energy-saving control circuit of onboard system, onboard system comprises master chip, communication module, external GPS equipment, all the other peripheral hardwares and power module, described master chip by bus respectively with described communication module, external GPS equipment and all the other peripheral hardwares connect, and described power module is master chip, communication module, external GPS equipment and the power supply of all the other peripheral hardwares, on onboard system, increase a micro controller system and a switch analog switch, described master chip, communication module connects power module by this micro controller system, and this micro controller system communicates by bus and master chip, described switch analog switch is connected in the bus between master chip and communication module, and this switch analog switch also connects described micro controller system by bus.Micro controller system just can be controlled power module whether to master chip power supply according to vehicle-state like this, and master chip during without electricity micro controller system and switch analog switch still can guarantee communication module work, thereby realize effectively energy-conservation.
Further, described master chip is to be connected with described communication module, external GPS equipment and all the other peripheral hardwares respectively by UART bus or usb bus; Described micro controller system communicates by I2C bus or UART bus and master chip; Described switch analog switch is to connect described micro controller system by UART bus or usb bus.
The utlity model has following advantage: the utility model only increases a micro controller system and a switch analog switch on onboard system, micro controller system serves as the power management module of master chip and communication module on the one hand, when not working, master chip still can guarantee that on the other hand communication module is in normal mode of operation, thereby realize when the energy-saving scheme of vehicle during in dead ship condition, therefore the utility model method is simple and reliable, with low cost, can actv. be that powerful device is energy-conservation.
