Abstract
The present invention relates to a kind of patrol machine, comprise liquid crystal display, CPU (central processing unit), CF card, MI Card Reader chip, wherein liquid crystal display, CF card, MI Card Reader chip are connected with CPU (central processing unit) respectively, also comprise, RC500 card read head for ID, battery detection unit, be connected with CPU (central processing unit) respectively, also comprise clock circuit and thumb-acting switch, be connected with CPU (central processing unit) respectively, described thumb-acting switch is ten thumb-acting switch, also comprise watchdog unit and 24C256EEPROM, all be connected with CPU (central processing unit).In the CF card, the kernel file under the assigned catalogue is extracted in the SDRAM zone, thereby finished the loading of kernel.Increasing the CF card has increased the information of patrol machine greatly, has increased night watching step, night watching personal information etc.
Description
Technical field
The present invention relates to a kind of patrol machine.
Background technology
The patrol machine in early stage need carry out host mostly and be connected with the actual of hardware circuit between Target Board when system debug, perhaps do not have effective debugging method.It is convenient inadequately to use, and the velocity ratio of burning sheet is slower, and the efficient of debugging is not high; Hardware aspect needs the support of jumbo Flash, has increased R﹠D costs; Carry out the underaction that seems when kernel upgrades.Hardware aspect needs the support of jumbo Flash, has increased R﹠D costs; Carry out the underaction that seems when kernel upgrades.
Need to store bulk information in the patrol machine, need the support of CF card, make full use of the CF card thus system kernel is stored.Benefit with this guidance mode is, need not a host and carry out hardware with Target Board and is connected when debugging, improved the efficient of debugging, and it is more convenient, more flexible to use; Carry out seeming more flexible when kernel upgrades that only need to dump to assigned catalogue upgrading kernel, its realization is also fairly simple in addition.
Summary of the invention
The purpose of this invention is to provide a kind of patrol machine, solve that patrol machine main frame commonly used burns that sheet speed is slow, efficient is high and carry out kernel inflexible problem when upgrading debugging the time.
Technical scheme of the present invention:
Patrol machine comprises liquid crystal display, CPU (central processing unit), CF card, MI Card Reader chip, and wherein liquid crystal display, CF card, MI Card Reader chip are connected with CPU (central processing unit) respectively.
Comprise that also RC500 card read head for ID, battery detection unit are connected with CPU (central processing unit) respectively.
Also comprise clock circuit and thumb-acting switch, be connected with CPU (central processing unit) respectively.
Described thumb-acting switch is ten thumb-acting switch.
Also comprise watchdog unit and 24C256EEPROM, all be connected with CPU (central processing unit).
In the CF card, the kernel file under the assigned catalogue is extracted in the SDRAM zone, thereby finished the loading of kernel.Increasing the CF card has increased the information of patrol machine greatly, has increased night watching step, night watching personal information etc.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structured flowchart of patrol machine of the present invention.
Embodiment
Patrol machine comprises liquid crystal display, CPU (central processing unit), CF card, MI Card Reader chip, and wherein liquid crystal display, CF card, MI Card Reader chip are connected with CPU (central processing unit) respectively.
Comprise that also RC500 card read head for ID, battery detection unit are connected with CPU (central processing unit) respectively.
Also comprise clock circuit and thumb-acting switch, be connected with CPU (central processing unit) respectively.
Described thumb-acting switch is ten thumb-acting switch.
Also comprise watchdog unit and 24C256EEPROM, all be connected with CPU (central processing unit).
This invention improvement place is on the basis of original BootLoader, increases mobile memory medium CF card to be carried out with the FAT form instruction of reading of data realizes.Its function is, in the CF card kernel file under the assigned catalogue extracted in the SDRAM zone, thereby finished the loading of kernel.Increasing the CF card has increased the information of patrol machine greatly, has increased night watching step, night watching personal information etc.
The concrete course of work of the present invention is:
The format of CF card, one-piece construction according to the FAT file system is made up of 4 major parts: MBR district (Main Boot Record district), DBR district (dos boot record district), (file allocation list area, FAT district, FAT1 is that master file distributes the list area, FAT2 is that backup file distributes the list area) and the DATA district (data field comprises the FDT district---the file directory list area).When format, realize the purpose that format is handled not being made in the most last 16MB zone of CF card memory area by the data that MBR district and DBR district are set, promptly it is changed to the RAW district.
CF is to the preservation of system kernel; By the system kernel of upper PC cross compile, and then pass through pc machine copy to above-mentioned RAW district.
The CF card is finished the start-up loading to system kernel.The realization of system kernel backup is instructed the system kernel code exactly and is filled into the RAW district by writing of CF card.The loading of system kernel is the kernel code that directly reads backup from the RAW district.
By change CF card program, just can directly change the patrolling management program among the LPC 2134 like this.
