Finally, communication module 14 is UART communication module, RS-285 communication module and MS-CAN logical in this embodiment of the utility model
Believe module, so that the cd-rom recorder 1 based on multiple types bus can be adapted to the driving in the different ends PC 2, and realizes the firmware of vehicle-mounted end 3
It is offline to update.
Specifically, as depicted in figs. 1 and 2, control chip 11 includes logic control element 111, operating status display unit
112 and buzzer alarm unit 113, operating status display unit 112, buzzer alarm unit 113 be all connected to logic control
Unit 111 processed.Wherein, 111 one side of logic control element is for executing the objective chip that source program is burnt to vehicle-mounted end 3
In, or executing will need the source program updated to be transferred in memory 12 by other equipment, on the other hand can be achieved to operation
The control of status display unit 112, buzzer alarm unit 113；And operating status display unit 112 is used for cd-rom recorder 1 for source
The display of operating status when program transportation is to vehicle-mounted end 3, or when debugging the objective chip program of vehicle-mounted end 3 for cd-rom recorder 2
The display of operating status, or the source program updated will be needed to be transferred to 12 luck of memory by other equipment for cd-rom recorder 2
The display of row state in the present embodiment as shown in figure 3, by LED diode displaying, and names LD1, LD2 respectively, with
LED's lights, extinguishes, flashing these three states to indicate the working condition of cd-rom recorder 2；Buzzer alarm unit 113 is then used for
Realize the function of alarm and reminding.
As shown in Figure 1, cd-rom recorder 1 carries out the mutual of working condition by interacting for heartbeat signal with the end PC 2 or vehicle-mounted end 3
It checks.When i.e. setting cd-rom recorder 1 and the end PC 2 or vehicle-mounted end 3 mutually be can not receive to square signal within a preset time, then burning is judged
Device 1 or the end PC 2,3 delay machine of vehicle-mounted end, in the case where wherein side's delay machine, system is out of service, waits in delay machine state
The cd-rom recorder 1 or end PC 2, vehicle-mounted end 3 are restarted or system continues to run, but data are directly stored in the cd-rom recorder 1 or PC of normal work
2, vehicle-mounted end 3 are held, after delay machine side restarts, then send data to delay machine side.Wherein, judge the end cd-rom recorder 1 and PC 2 or vehicle-mounted
End 3 between whether normal preset time be not more than 1 minute, when there are problem, or occur certain symptom need handle but temporarily
When will not influence normal operation and the variation of cd-rom recorder 1 in error range when, done by buzzer alarm unit 113
The instruction information that refusal is used, alerts or normally enabled out.
As shown in Fig. 2, be stored in logic control element 111 firmware offline in more new system each component normal work ginseng
Several and/or working life information, can be judged according to the normal operating parameters and/or working life information of each component its whether needs
Replacement or maintenance realize if so, control buzzer alarm unit 113 carries out local warning to each component working condition
Warning function reminds staff's replacement or maintenance in advance, prevents failure, improves working efficiency.
As shown in figures 1 and 3, by 12 division operation of memory, according to physical address can be divided into Flash1 memory and
The area Flash2 memory Liang Ge, wherein stores Firmware program in Flash1 memory, Firmware program has cd-rom recorder 1
Some functions include the realization of the realization of usb 13, communication module 14, and offline update institute is in addition stored in Flash2 memory
The source program needed.This configuration has improved the logics of 12 storing data of memory, and improve the operational efficiency and fortune of cd-rom recorder 1
Row stability improves whole performance and quality.
As shown in figure 3, the standard compliant USB2.0 agreement of the VBUS electric signal of usb 13, passes through external equipment
Standard USB interface provides 5V DC power supply to cd-rom recorder 1, solves the powerup issue of cd-rom recorder 1.Wherein, the HID of usb 13
Agreement is stored in memory 12 as a part of Firmware program.In this embodiment of the utility model, chip is controlled
11 be GD32F103 single-chip microcontroller, and highest works dominant frequency as 108Mhz, and Flash is up to 3MB, and RAM is up to 96KB, and can guarantee
Size of cores area is minimum.
Because being easy to misread the system update data being stored in cd-rom recorder 1 using the vehicle-mounted end 3 of offline update mode, make
At improper update.Therefore to solve this problem, as shown in Figure 1, vehicle-mounted end 3 include trigger unit 31, search unit 32 and
Updating unit 33；Wherein, when trigger unit 31 is used to obtain the more new command of the cd-rom recorder 1, software upgrading event is triggered；It searches
Cable elements 32 are for searching for the file for having more new logo in the cd-rom recorder 1；Updating unit 33 is for reading in the cd-rom recorder 1
There is the file of more new logo, carries out the update of software.I.e. after cd-rom recorder 1 is connect with vehicle-mounted end 3, the specific steps that update offline
As follows, trigger unit 31 triggers the software upgrading time when obtaining preset more new command.After the triggering of software upgrading event,
There is the file of more new logo by the search of search unit 32, the text with more new logo is then read by updating unit 33
Part carries out the update of software, to improve the usage experience of user.
Based on the working principle of the firmware more new system offline of multiple types bus: first at the end PC 2 by firmware update journey
Sequence downloads in cd-rom recorder 1, is then that product progress firmware update specifically works as burning in vehicle-mounted end 3 by the cd-rom recorder 1
After device 1 is connect with vehicle-mounted end 3, trigger unit 31 obtains preset more new command, the software upgrading time is triggered, in software upgrading thing
After part triggering, there is the file of more new logo by the search of search unit 32, then has by the reading of updating unit 33 and update
The file of mark carries out the update of software.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
