理を行う装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is not affected by the turning on / off of the power supply of a device, and the replacement of a substrate is performed by using device-specific information such as a life counter of a maintenance part in the device and system setting information. The present invention relates to an apparatus that performs consistent management from the start-up of the apparatus to disposal without losing the life of the battery.

の情報を保持する必要がある。When using a component having a life, the life is recognized based on the number of times the component is used, the installation period, and the like, and maintenance replacement is required. Therefore, a counter is provided according to the number of times of use, the installation period, etc., the life is recognized, and the counter is cleared by maintenance replacement.
Such a life counter and other device-specific information are frequently rewritten when the power is turned on, and it is necessary to hold this information even when the power is turned off.

とられていなものも問題である。In the above-described conventional technology, when a RAM is used as a nonvolatile memory, a battery backup is required to retain information even when the power of the apparatus is turned off. If the battery life is recognized and the battery is not replaced, the information will be lost. When a dedicated memory is prepared, there is a problem that the capacity becomes large on the hardware side such as a battery backup and a battery life recognition circuit. The same applies when non-volatile memory for other purposes is used or when dedicated memory is mounted on the same board, but if the board is replaced for any kind of failure or maintenance, the whole memory will be lost. There is a problem of losing information. Also, there is a problem that no recovery measures are taken when the memory contents are destroyed for some reason.

ブリットICを用いる。これらをCPU6が操作する。FIG. 1 is a configuration diagram of one embodiment of the present invention. In the figure, a battery built-in RAM is used for the nonvolatile memory 1. The battery built-in RAM 1 is mounted so as to be separable from the device board by an IC socket. A part of the firmware RAM 3 is used for the nonvolatile memory 2. The firmware RAM 3 has a battery backup 4, and the battery life can be detected by the battery voltage drop recognition circuit 5. The battery voltage drop recognition circuit 5 uses a battery backup hybrid IC that recognizes a battery voltage drop and notifies a battery alarm. These are operated by the CPU 6.

上に存在する。The nonvolatile memory 1 is used as a device-specific information exclusive memory, and the nonvolatile memory 2 is considered as a backup, and the contents of the nonvolatile memory 1 are copied to the nonvolatile memory 2. FIG. 2 is a flowchart showing the timing of copying the contents.
Copying is performed at the same time as loading the firmware onto the firmware RAM3 when starting up the device and replacing the board. Thereafter, when the contents of the non-volatile memory 1 are rewritten, the backup area is also rewritten at the same time, so that the same contents as the non-volatile memory are always updated in the firmware RAM 3.
Present on.

る。When the apparatus is powered on, the contents of the non-volatile memory 1 are compared with the contents of the non-volatile memory 2 as a backup area on the firmware RAM 3 at the time of memory diagnosis as shown in FIG. Here, it is possible to discover when the nonvolatile memory 1 is destroyed due to the life of the battery. When the non-volatile memory 1 is replaced, recovery can be performed only by copying the non-volatile memory 2. Non-volatile memory 2 is firmware
Since the contents are guaranteed in the memory of the RAM 3, an error in this comparison can be determined to be an error of the nonvolatile memory 1.

固有情報は保持される。When a board is replaced for trouble, maintenance, or the like, the nonvolatile memory 1 is an IC socket type, so that the device-specific information is retained by removing the nonvolatile memory 1 from the device board before replacement and transferring it to the device board after replacement.

を高める効果がある。As described above, the present invention stores the device-specific information, which is maintained from start-up to disposal of the device, in the nonvolatile memory on the device substrate and the nonvolatile memory separable from the device substrate. This has the effect of maintaining information without being affected by power-on and power-off, replacing the board and losing information over the life of the battery, and improving the reliability and security of the information.
