Abstract

The utility model provides a vehicle-mounted timing system and a car with the vehicle-mounted timing system. The vehicle-mounted timing system receives time information of a global position system (GPS) satellite through a GPS signal receiving and processing module and transfers the time information into calibration time information which is transmitted to a timing receiving module through a vehicle-mounted network module, and the timing receiving module receives the calibration time information and sets system time on the basis of the calibration time information. The system time which is set so is slightly affected by outside world, high in accuracy, unnecessary to be manually adjusted and easy to unify.

Preferably, described timing receiver module is human-computer interaction device.

Preferably, described human-computer interaction device is the combination instrument module with time display function.

Preferably, described timing receiver module is drive recorder.

The utility model also provides a kind of automobile, has above-mentioned vehicle-mounted timing system.

The utlity model has following beneficial effect:

Vehicle-mounted timing of the present utility model system receives the temporal information of gps satellite and is converted to alignment time information by the gps signal receiving processing module, the In-vehicle networking module passes to the timing receiver module with alignment time information, and the timing receiver module receives alignment time information and according to alignment time information setting system time.The system time of so setting is subjected to that ectocine is little, precision is high, need not manual adjustment, be easy to unified.

Description of drawings

Fig. 1 is the structural representation of vehicle-mounted timing of the present utility model system.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

Please refer to Fig. 1, the utility model embodiment provides a kind of vehicle-mounted timing system 100 that is arranged on the automobile, comprises gps signal receiving processing module 110, In-vehicle networking module 120 and timing receiver module 130.

Gps satellite 200 communications of described gps signal receiving processing module 110 and outside, be used for receiving the wireless gps data that gps satellite 200 sends, extract the temporal information in the wireless gps data, temporal information is decoded and is converted to the alignment time information that timing receiver module 130 can be identified.In the present embodiment, the DVD(Digital Versatile Disc of described gps signal receiving processing module 110 for having the GPS positioning function, digital versatile disc) navigation module.In other embodiments of the present utility model, described gps signal receiving processing module 110 also can be vehicle GPS receptor or other GPS navigation systems.

Described In-vehicle networking module 120 is used for connecting described gps signal receiving processing module 110 and timing receiver module 130, passes to described timing receiver module 130 so that described gps signal receiving processing module 110 is processed the alignment time information that obtains.In the present embodiment, described In-vehicle networking module 120 is CAN(Controller Area Network, controller local area network) mixed-media network modules mixed-media.In other embodiments of the present utility model, described In-vehicle networking module 120 also can be MOST(Media Oriented System Transport, system transmissions towards media) network, LIN(Local Interconnect Network, local internet network) network or WiFi, bluetooth, the wireless network such as infrared.

Described timing receiver module 130 receives described alignment time information, and according to described alignment time information setting system time.

Described timing receiver module 130 can carry out time calibration automatically receiving the alignment time during information, and the mode of automatic time correction can be that mode or relatively adjustment mode etc. are adjusted in adjustment mode, interval in real time.

Described real-time adjustment mode is: receive in real time described alignment time information and be set and be system time.

Described interval adjustment mode is: every a set time, be system time with the alignment time information setting that receives.

Described relatively adjustment mode is: after receiving described alignment time information, described timing receiver module 130 compares himself system time and alignment time information; When both time differences surpassed predetermined value, such as 1 second, described timing receiver module 130 was made as system time with the time value of described alignment time information.

So by being close to real-time adjustment function, reduced the accuracy requirement to clock crystal oscillator, provided cost savings, and with automatic time correction replaced traditional manually to the time mode, promoted convenience.

In the present embodiment, described timing receiver module 130 comprises in human-computer interaction device 131 and the drive recorder 132 one or all.

Described human-computer interaction device 131 has time display function, and its temporal information that sets is presented on the LCDs.In the present embodiment, described human-computer interaction device 131 is for having the combination instrument module of time display function.

Described drive recorder 132 is used for the various status informations of record automobile, such as time, the speed of a motor vehicle, automotive interior or outside image etc.Described drive recorder 132 also can send the various status informations that comprise temporal information to outside supervisory systems 150 by wireless network, makes things convenient for the relevant personnel to monitor.

The vehicle-mounted timing of the utility model system 100 receives the temporal information of satellite 200 and is converted to alignment time information by gps signal receiving processing module 110, In-vehicle networking module 120 passes to timing receiver module 130 with alignment time information, timing receiver module 130 receives described alignment time information, and according to described alignment time information setting system time.The system time of so setting can be accurate to Millisecond according to the standard time clock of satellite, the rear car load clock accuracy of correction is significantly promoted, so that the time unification of car load has been avoided the inconsistent trouble that causes of each current consumer clock.

The utility model embodiment also provides a kind of automobile, comprises the vehicle-mounted timing system in above-described embodiment.
