摘要： PROBLEM TO BE SOLVED: To avoid the storage of data having an indefinite value from a volatile memory to a nonvolatile memory even if a power source is cut off after power activation or power recovery.SOLUTION: In a digital type protection relay system 1, after power activation or power recovery, a CPU 2 performs setting for masking a maskable interruption. After the data in an EEPROM 5 is extracted to a RAM 4, the CPU 2 sets the maskable interruption into a non-mask state, receives a power source cutoff signal S1 from a power source cutoff detection section 6, and enables interruption processing due to the power source cutoff.

摘要： PROBLEM TO BE SOLVED: To reduce writing of data and the like from a nonvolatile memory to a storage medium in occurrence of a momentary power failure and the like for preventing generation of an undefined value even when a device power supply is turned on during storage of the data from the storage medium to the nonvolatile memory. SOLUTION: By interruption in a power failure of the device power supply or in power supply turn-off operation, data of the storage medium such as a RAM 1 2 are stored in a backup RAM 1 4 equipped with a short-time specification backup power supply and an EEPROM 1 3 . When a normal keyword is not written in the backup RAM in recovery of the device power supply or in power supply turn-off operation, the data and keyword stored in the EEPROM are written in the backup RAM. In the case of a power failure of the device power supply or in turn-off operation, the data in the backup RAM are stored in the nonvolatile memory only when the normal keyword is written in the backup RAM.

SOLUTION: Data communication is performed between a monitor terminal device and a server 2 by using radio communication channels, and the monitor terminal device is composed of a master device 1 and a plurality of slave devices 4 LAN-connected to the master terminal device through a hub 5. The master device is connected to the server by a single channel of the radio communication channels, and receives downlink data from the server, while transmitting uplink data to the server. The hub transfers the downlink data to the slave terminal device having a data transfer destination number added to the data. The master device is equipped with an IO means to incorporate the transfer destination number when the number is for itself. The master unit transmits the data from the slave devices to the server, while temporarily preserving them in a buffer, and transfers the data from the server to the slave devices, while temporarily preserving them in the buffer.
