Problems solved by technology

[0003] The object of the present invention is to provide an instrument for guiding, upgrading and maintaining based on USB Host to solve the defects of inconvenient software upgrading, maintenance and correction of traditional instruments. The volatile memory, a central processing unit, is connected with the read-only non-volatile memory, and the instrument also includes: a USB Host interface, which is connected with the central processing unit; Afterwards, the central processing unit loads the boot program into the central processing unit from the read-only non-volatile memory and starts running; the boot program judges whether there is a mobile storage access through the USB Host interface, and if there is data read from the mobile storage, judge Whether there is a boot requirement; if it is a mobile memory boot, the data in the mobile memory is loaded into the central processing unit through the USB Host interface for execution

Embodiment 1

[0042] The instrument was suddenly powered off during the software upgrade process, resulting in incomplete code or data, resulting in the system not being able to start or run normally. At this time, you can use the USB removable storage device that comes with the instrument to boot the system, and then upgrade the software. This avoids the hassle of going to a repair center or returning to the factory for repairs. The specific working process is:

[0043] Turn on the power, load the boot program from the read-only non-volatile boot memory into the internal memory of the central processor, and execute it;

[0044] Insert the mobile memory (U disk) storing the boot program into the USB Host;

[0045] Read the boot sector on the U disk to determine whether the boot is valid (here is valid);

[0046] U disk booting is valid, whether to perform U disk booting according to the user's instructions;

[0047] Choose to boot from U disk, load the boot program on the U disk into th...

Embodiment 2

[0050] Instruments have different system parameters, some are critical and only a few people have the right to correct it. Some other parameters are relatively open, and ordinary users may often need to modify it. In this way, users with different permissions are equipped with different USB mobile storage devices and configure password protection at the same time. When the user needs to maintain these parameters, after booting with the USB Host, enter the corresponding password to obtain the corresponding authority and perform the corresponding operation. And the user can also change the password at this time. The specific working process is:

[0051] Turn on the power, load the boot program from the read-only non-volatile boot memory into the internal memory of the central processor, and execute it;

[0052] Insert the mobile memory (U disk) storing the maintenance program into the USB Host;

[0053] Read the boot sector on the U disk to determine whether the boot is vali...

Embodiment 3

[0061] During the development process of the instrument, there will be many test versions, which are only the characteristics of the temporary test version, and it is not expected that this version will be used for a long time. After booting through the USB Host, the test version software can be directly copied to the running space of the software to run without overwriting the original version. After the test is stable, choose to upgrade. This ensures a reliable transition between beta and stable releases. The specific working process is:

[0062] Turn on the power, load the boot program from the read-only non-volatile boot memory into the internal memory of the central processor, and execute it;

[0063] Insert the mobile memory (U disk) storing the maintenance program into the USB Host;

[0064] Read the boot sector on the U disk to determine whether the boot is valid;

[0065] If the U-disk booting is valid, whether to perform U-disk booting according to the user's ins...

Abstract

This invention discloses a kind of device with using the USB interface to finish the device guidance, stage, and maintenance which includes: one read-only nonvolatile memory memorizing the guide program, one central processor which connects with the read-only nonvolatile memory and one USB Host interface which connects with the central processor. This device includes a protected system guide memory and a USB Host interface and the protected system guide memory locates a USB Host drive and a guide stage maintenance code in it so it can finish the work of self guidance, stage, and maintenance effectively further ensure the highly active and reliable running and working of the device system.

Description

technical field [0001] The invention relates to an instrument for guiding, upgrading and maintaining based on a USB Host and a method thereof, in particular to guiding the instrument through a USB Host interface, upgrading the software of the instrument, and maintaining the system parameters of the instrument. Background technique [0002] The instrument is a complete system composed of hardware and software. The software is an elastic system relative to the hardware, and will be continuously upgraded according to market demand and version updates. At the same time, the system parameters of the instrument must be calibrated or corrected according to the usage. The traditional non-operating system-based instruments are all software systems of a single version. If there is a problem with the software, they must go back to the maintenance center or the factory to unpack and upgrade. Even if there are other external upgrade methods, if an unexpected situation interrupts the upg...
