Description

How to simplify program backup in an electronic simplified exchange device {METHOD FOR PROGRAM BACKUP IN KEYPHONE SYSTEM}

The present invention relates to an electronic simplified switching device, and more particularly, to a method for simplifying program backup for easily setting the changed user function data upon initialization and replacement of the electronic simplified switching device operated from basic data.

In general, a variety of basic functions are provided in an electronic switching system (keyphone system). The basic functions are permanently stored in the nonvolatile memory ROM as an operating program. The basic functions are basically set by the manufacturer and shipped. The basic data stored in the ROM is user function data stored at the corresponding area of the RAM when the power is turned on. The data stored in the RAM is not erased even when the main power supply is disconnected by a battery, which is an auxiliary power supply. The user changes the basic data according to the user's environment and needs. At this time, the change data stored in the RAM and changed to match the user's environment is referred to as user function data. Such operations are performed via a keyphone terminal or a personal computer.

The user function data stored in the RAM is erased during initialization and replacement of the electronic simplified switching device, and the electronic simplified switching device operates with the basic data stored in the ROM. Accordingly, the user must change the basic data to reset to the user function data, which is the previous system operation environment.

In other words, the conventional problem is that the user function data changed by the user must be backed up and re-stored in the RAM of the electronic simplified switching device during initialization and replacement of the electronic simplified switching device. It takes a lot of time and effort, and there was a lot of errors due to the user's incorrect entry.

Accordingly, an object of the present invention is to solve the above problems in the electronic simplified switching system to display the changed data by comparing the basic data preset in the electronic simplified switching device and the user function data changed by the user. It provides a method to simplify program backup.

In order to achieve the above object, the present invention compares basic data of a ROM with user function data of a RAM when the data backup function mode is set, and prints only the data which is not identical or outputs it to the display means of the terminal.

3 is a control flowchart of a control unit for data backup according to an embodiment of the present invention;

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

1 is a block diagram of an electronic simplified exchange device for implementing the present invention. Hereinafter, a description will be given with reference to FIG. 1. The controller 110 controls the call switching and overall control of the electronic simple switching apparatus, for example, the key phone system 100, to provide various services to the user. The ROM 120 stores basic data on an operator program that stores the operation of the key phone system 100 in a program form, and the RAM 130 stores the basic data when the key phone system is powered under the control of the controller 110. Copy it to and save it. The user function data is changed and stored by the user. The key phone terminal interface 140 forms a connection between the key phone terminal 150 and the key phone system 100 to interface the transmission and reception signals. The key phone terminal 150 is used by the user to change the key phone function. In addition, the keypad 150 is provided with a liquid crystal display means to display a display signal under the control of the controller 110. The printer unit 160 drives the print under the control of the controller 110.

2 is a flowchart of a process for an updater of user function data according to an embodiment of the present invention. Hereinafter, referring to FIG. 1, when the user turns on the key phone system 100 in step 211, the controller 110 stores the basic data (initial value) of the key phone system 100 stored in the ROM in step 212. Copy to and use as user function data. Thereafter, when the user sets the function change mode through the key input unit of the keypad terminal 150, the step 213 is shifted to step 215. If the function change mode is not set in operation 213, the controller 110 performs a corresponding function in operation 214. The control unit 110 set to the function change mode in step 215 updates the user function data according to the user's environment and needs. That is, the controller 110 updates the user function data stored in the RAM 130 according to the user's processing and repeats the process of storing the RAM 130 again. The RAM 130 always has only newly changed user function data, and all functions of the key phone system 100 are updated. Is performed based on user function data stored in the RAM 130.

3 is a control flowchart of a control unit for data backup according to an embodiment of the present invention. This is a flow chart of FIG. 2 and later. When the user is set to the data backup function mode in step 311 in order to receive the changed user function data during system initialization and system replacement, the control unit 110 compares the basic data of the ROM 120 in step 313. Compare the user function data of RAM 130. Thus, if there is no difference between the two data in step 314, the result is that the user did not change the function. In step 315, the same message is displayed using the liquid crystal display means of the printer unit 160 or the keypad 150. On the other hand, when there is a difference between the two data in step 314, only the changed data of the basic data and the user function data of the key phone system 100, that is, the part where the user changes the function, is searched. The change data is displayed by means.

As described above, the present invention can be easily backed up using only the changed data even when the system is initialized or replaced by changing the basic data according to the user's environment. There is an advantage to reduce.
