Preferably, the vehicle-mounted TBOX further includes signal input module and signal output module, and the CPU module connects institute
Signal input module and signal output module are stated, it is described that dormancy instruction or vehicle are detected by CAN communication module when CPU module
When static first setting time, CPU module also sends suspend mode control letter to the signal input module and signal output module
Number, so that signal input module and signal output module is worked in dormant state.
Preferably, first setting time is 20 minutes, and second setting time is 30 seconds.
The beneficial effects of the present invention are: when vehicle-mounted TBOX detects dormancy instruction or stationary vehicle certain time, CPU
Other each modules of module into TBOX send corresponding dormant control signal, other each modules is made to work in dormant state,
The power supply for controlling other each modules makes these modules enter dormant state by standby mode, then, the quiescent current of each module is big
Amplitude reduction thereby reduces the quiescent current of entire TBOX, and dormancy power consumption is greatly lowered, and extends the use of vehicle-mounted TBOX
Service life, and then the power-on time and service life of battery are extended, even if stock idle also can normally start for a long time,
Vehicle maintenance expense is effectively reduced.
Detailed description of the invention
Fig. 1 is the composed structure schematic diagram of existing vehicle-mounted TBOX；
Fig. 2 is the composed structure schematic diagram of vehicle-mounted TBOX provided by the invention.
Specific embodiment
Referring to fig. 2, the present embodiment provides a kind of vehicle-mounted TBOX, including CPU module, GPS module, gsm module, power supply mould
Block, CAN communication module, bluetooth module, serial communication modular, signal input module and signal output module.Wherein, CPU module
For the core of data processing and the control of vehicle-mounted TBOX, in order to further decrease power consumption when vehicle-mounted TBOX suspend mode, CPU module is
Low power consumption CPU device, it might even be possible to choose ultra low power devices；GPS module is used for bus location；Gsm module is used for and movement
Terminal (such as mobile phone) communication, receives the coherent signal of mobile phone transmission；Power module is used to provide working power for vehicle-mounted TBOX；
CAN communication module with vehicle body CAN bus for being connected, and to be communicated with vehicle body CAN bus, receives the correlation of vehicle body CAN
Signal sends coherent signal to vehicle body CAN bus；Bluetooth module is used for and other relevant devices bluetooth connection；Serial communication
Module is used for and other relevant devices serial communication；Signal input module is used to receive the related letter of other relevant devices sending
Number；Signal output module is used to send signal to other relevant devices.Table 1 provides the model of several correlation modules, wherein GSM
Indicate that gsm module, GPS indicate that GPS module, bluetooth indicate that bluetooth module, CAN indicate CAN communication module, MCU indicates CPU mould
Block, power supply indicate that power module, serial ports indicate serial communication modular.Last column indicates the brand of each module in table 1.
Table 1
For the power input of power module for connecting battery (automobile batteries in corresponding diagram 2), the power supply of power module is defeated
Outlet connects GPS module, gsm module, CAN communication module, bluetooth module, serial communication for being electrically connected CPU module, CPU module
Module, signal input module and signal output module.
When CPU module detects by CAN communication module the dormancy instruction in vehicle body CAN bus, (dormancy instruction can be with
Issued by entire car controller) or the first setting time of stationary vehicle (can by detect car speed judge whether vehicle quiet
Only, here, the first setting time is 20 minutes, it is, of course, also possible to be set as other times) when, CPU module control reduces certainly
The working frequency of body, and mould is inputted to GPS module, gsm module, CAN communication module, bluetooth module, serial communication modular, signal
Block and signal output module send dormant control signal, turn off the power supply power supply of these modules, make the work of these modules in suspend mode
State.Moreover, after CPU module sends dormant control signal to these modules, at interval of the second setting time (here, second
Setting time is 30 seconds, it is, of course, also possible to be set to other times) heartbeat is sent to vehicle body CAN bus by CAN communication module
Packet, to export the working condition of each module.
After vehicle-mounted TBOX enters dormant state, the power supply of each module is turned off, extends the service life of vehicle-mounted TBOX complete machine.Moreover,
After vehicle-mounted TBOX enters dormant state, complete machine electric current is down to 20-30mA, is put even if vehicle is static down to 3mA, vehicle suspend mode battery
It sets 1 month, moreover it is possible to which vehicle maintenance expense is effectively reduced in normal starting.
In above-described embodiment, in vehicle-mounted TBOX include serial communication modular, signal input module and signal output module, when
So, it in subsequent control, needs to send dormant control signal to these modules.As other embodiments, serial communication modular,
Signal input module and signal output module can be selectively arranged according to actual needs, or be not provided with, then, subsequent
In control, dormant control signal only is sent to the module of setting.
In above-described embodiment, before CPU module sends dormant control signal to other each modules, CPU module control drop
Itself low working frequency, can reduce the power consumption of itself, and certainly, this is a kind of embodiment of optimization, general as other
Embodiment, CPU module can not also reduce the working frequency of itself, work in original working frequency.
In above-described embodiment, after CPU module sends dormant control signal to these modules, at interval of the second setting time
Heartbeat packet is sent to vehicle body CAN bus by CAN communication module, for exporting the working condition of each module, certainly, this is one
The embodiment of kind optimization is then just not necessarily to vehicle body CAN bus if you do not need to monitoring the working condition after vehicle-mounted TBOX suspend mode
Send heartbeat packet.
A kind of above-mentioned to be merely given as specific embodiment, on the basis of the embodiment, to each realization rate deformation
It should all be included in the protection scope of the present invention.
