Technical Field

[0001] The present invention relates to the field of intelligent control, and in particular to a CORS terminal host, an automatic backup and recovery method, and a storage device. Background Art

[0002] At present, in order to achieve real-time dynamic high-precision positioning, GNSS (Global Navigation Satellite System) terminal handheld devices and RTK (Real-Time Kinematic) must receive differential data transmitted by CORS (Continuous Operating Reference System) in real time.

[0003] At present, in order to generate and send stable and accurate differential data, many perfect CORS networks have been established across the country. The CORS network is composed of many CORS terminal hosts connected to the network. Therefore, the stability of the CORS terminal host is related to the security of the entire CORS network.

[0004] The CORS terminal hosts on the market mainly run the Linux operating system. However, since most CORS terminal hosts are placed in remote places without human supervision, once the host fails to function properly, the Linux system files will be damaged and the system will be unable to restart. It will require professionals to manually handle it in person to restore it to normal. Therefore, it takes a lot of time, manpower and financial resources. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the present invention proposes a CORS terminal host, an automatic backup and recovery method and a storage device. An EEPROM memory is set on the CORS terminal host, and the characteristics of the EEPROM memory are used to save data, thereby preventing the data from being affected by power outages. The system is backed up and restored through the state of the F1 flag, and can be automatically restored when the system is damaged. Manual processing by professionals is unnecessary, which saves time and reduces the consumption of manpower and material resources.

[0006] To solve the above problem, a technical solution adopted by the present invention is: a CORS terminal host automatic backup and recovery method, the CORS terminal host has a built-in EEPROM memory, and the CORS terminal host automatic backup and recovery method comprises: S101: reading the F1 flag of the EEPROM memory, judging whether the F1 flag is a first preset flag, if so, executing S102, if not, executing S103; S102: starting the system, and backing up the system to a memory card after the system is started, and modifying the F1 flag to a second preset flag; S103: judging whether the F1 flag is the second preset flag, if so, executing S104, if not, executing S105; S104: starting the system, and modifying the FI flag according to the startup status of the system; S105: determining that the F1 flag is a third preset flag, booting the system from the memory card, copying the system backup in the memory card to a preset storage location of the system, and restarting the CORS terminal host after modifying the F1 flag to the second preset flag.

[0007] Furthermore, the step of starting the system specifically includes: guiding the system to start, modifying the F1 flag to a third preset flag, and starting the CPU hardware watchdog.

[0008] Furthermore, the NFC tag includes an NFC memory, and the physical address of the WiFi module and the built-in web page IP address of the RTK host are stored in the NFC memory.

[0009] Furthermore, the step of modifying the FI flag according to the startup status of the system specifically includes: determining whether the system starts normally; if so, starting an application, and using the application to periodically feed the CPU hardware watchdog and modify the F1 flag to a second preset flag; if not, keeping the F1 flag at a third preset flag.

[0010] Furthermore, after the step of maintaining the third preset flag at the F1 flag bit, the method further includes: restarting the CORS terminal host through the CPU hardware watchdog.

[0011] Furthermore, before the step of backing up the system to the memory card, the step also includes: starting an application program, and feeding the CPU hardware watchdog through the application program.

[0012] Furthermore, the step of copying the system backup in the memory card to the preset storage location of the system specifically includes: starting an application, and copying the system backup in the memory card to the preset storage location of the system through the application.

Figure 1-3 The CORS terminal host automatic backup and recovery method of the present invention is described in detail.

[0025] In this embodiment, the CORS terminal host has a built-in EEPROM memory. In other embodiments, a hard disk, a floppy disk, a VGA BIOS, a CMOS, and other storage devices that support storage and read-write can also be set in the CORS terminal host.

[0026] In this embodiment, the CORS terminal host automatic backup and recovery method includes:

[0027] S101: Read the F1 flag of the EEPROM memory to determine whether the F1 flag is a first preset flag. If so, execute S102; if not, execute S103.

[0032] S102: Start the system, and after the system starts, back up the system to the memory card, and modify the F1 flag to a second preset flag.

[0033] In this embodiment, the step of starting the system specifically includes: guiding the system to start, modifying the F1 flag to a third preset flag, and starting the CPU hardware watchdog.

[0034] In this embodiment, when the CORS terminal host confirms through the boot program that the F1 flag is the first preset flag, the boot system is started from Nandflash.

[0035] In a specific embodiment, the third preset flag is 0x2, and the CORS terminal host modifies the F1 flag bit to the third preset flag through a boot program.

[0036] In this embodiment, after the system is started, an application for feeding the CPU hardware watchdog and backing up the system is started, the watchdog is fed and the system is backed up through the application, and the system backup is copied to the memory card to implement the system backup. After the backup is successful, the F1 flag of the EEPROM memory is modified to the second preset flag through the application.

[0037] In this embodiment, the application program may be stored in the form of an APP on the CORS terminal host.

[0038] In a specific embodiment, the second preset flag is 0x1, and the second preset flag represents that the system is normal (ie, represents that the system has been started normally).
