Description

Data backup device of communication equipment

The present invention relates to a back-up device of the operation and setting state of the communication equipment, and in particular, the data backup device of the communication equipment to reproduce the original information without loss when the power supply to the equipment is normally supplied after a momentary power failure It is about.

1 is a block diagram of a data backup unit of a conventional data communication unit (DCU). As shown, the data communication unit 10 and the memory card unit 20 are configured. The data communication performing unit 10 backs up the system initialization information and the stored data set by the operator to the memory card performing unit 20 to prevent the initial information loss of the system information due to a power failure or an incorrect operation.

The memory card performing unit 20 executes the device operation software in a specific area by uploading / downloading (data backup) the system initialization information and the stored data stored in the memory of the monitoring control unit (MCU) using a command. keep it.

The memory card of the memory card performing section 20 has a capacity of 1 megabyte and the stored data retention period is about 3 to 4 years.

2 shows a configuration diagram of a supervisory control unit (MCU) 100 that provides data to be backed up to the memory card performing section 20.

As illustrated, the intra communication unit 110 includes a boot up and operation program execution unit 120, a CPU control unit 130, a backup execution unit 140, and a memory 150.

The RS-232, the intra communication unit 110 performs the function of connecting the operating terminal and the communication between the equipment and the equipment (Intra).

The boot-up and operation program execution unit 120 operates in conjunction with the CPU control unit 130 to operate the device by operating a boot-up program and an operating system (operating system) during the initial operation of the device.

The CPU controller 130 is responsible for alarm monitoring and control, operation program execution, and command execution.

The backup execution unit 140 transmits, by a command, the setting data stored in the D-memory, which is the memory 150 of the supervisory control unit (MCU), to the memory card of the data communication unit.

The memory unit 150 is configured as a D-memory, and the operator stores equipment setting data.

The monitoring control unit (MCU) configured as described above temporarily stores both the channel configuration information set by the operator and the setting value of each channel in the memory unit 150. At this time, without the external command, the stored data of the memory unit 150 cannot be backed up to the memory card unit 20 of the data communication unit (DCU).

The conventional technology as described above is to store the system information and software in the memory card unit 20 in the data communication unit (DCU), and the monitoring control unit (MCU) by the equipment setting command when the set information is backed up Information stored in the memory memory 150 is stored in the memory card 20.

Therefore, the following problems are encountered.

1) Currently, backup function is only in memory card of data communication unit (DCU), so the important equipment setting information backup function of equipment is weak.

2) The memory card may be lost or damaged (the memory card protrudes about 2cm from the front of the system).

3) It does not save system setting contents immediately (it can be transmitted by command), which causes inconvenience to the operator.

4) Short life of memory card (3 ~ 4 years)

In order to solve the problems as described above, the present invention is intended to solve the problems as described above, and does not perform a backup function by a setting command. It is an object of the present invention to provide a data backup device of a communication device that enables a very high speed backup.

The data backup device of the communication equipment according to the present invention for achieving the above object receives the system setting information of the CPU from the memory in the supervisory control unit (MCU) based on the external command of the operator and backs up to the memory card in the data communication unit. A data backup device comprising: a backup execution unit configured to receive system setting information of a CPU via a data bus and an address bus in a supervisory control unit (MCU), store the information in a nonvolatile memory, and back up the system setting information of the CPU. It is characterized by including the configuration.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is a detailed configuration diagram of the backup performing unit 140 installed in the monitoring control apparatus according to the present invention.

As shown, a data bus unit 141 for transmitting data in association with the CPU control unit 130, an address bus unit 142 for transmitting an address in connection with the CPU control unit 130, and the data. A nonvolatile memory unit 143 which is a backup performing unit for backing up the data of the CPU control unit 130 through the bus unit 141 and the address bus unit 142 is configured.

Looking at the data backup process in the backup device including the backup performing unit 140 configured as described above are as follows.

The system setting information data of the CPU control unit 130 is periodically stored in the memory unit 150 and then transferred to the memory card unit 20 in the data communication unit (DCU) by the operator's command operation and backed up.

On the other hand, the backup performing unit 140 is stored in the nonvolatile memory unit 143 directly through the data bus 141 and the address bus unit 142 associated with the CPU control unit 130. While system setting information stored in the memory unit 150 is erased by data such as an outage, the data stored in the nonvolatile memory unit 143 in the backup performing unit 140 is stored even in the event of a power outage. Is preserved. In addition, although it takes some time to back up from the memory unit 150 to the memory card unit 20 based on an external command of the operator, the nonvolatile memory unit 143 is formed in the backup performing unit 140. Since the data backup is stored directly through the data bus 141 and the address bus unit 142 without the operation of an external command by the operator, the system setting information of the CPU control unit 130 can be backed up at a very high speed. do.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and it is common knowledge in the technical field to which the present invention pertains that various substitutions, conversions, and changes can be made without departing from the technical idea of the present invention. It will be apparent to those who have

According to the present invention, it is possible to solve the disadvantage that the system information is not smoothly backed up due to a failure of a data communication unit or a bad memory card, and the trouble of an operator performing a backup function using a conventional command. By using nonvolatile memory that does not erase contents during power failure in the supervisory control unit, the information set by the operator is immediately stored, which greatly affects the reliability and stability of the system due to the duplication of the setting information.
