BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically resetting a key phone, and more particularly, to a method for automatically resetting a key phone that detects an error in a key phone connected to a key system and automatically resets the error.

In recent years, with the development of software technology and hardware technology, the functions of a key system having a plurality of general telephones and a key telephone telephone are increasingly diversified, and the use of the key system has been widely used in offices and hotels.

On the other hand, in a plurality of key phone phones connected to the key system as described above, if an error on the program or an error that is executed in an infinite loop while using the key phone phone occurs, the operator has to manually reset manually. There is this.

Accordingly, an object of the present invention is to provide a method for automatically resetting a phone phone that can be automatically reset by detecting an error of the phone phone.

In order to achieve the above object, the present invention provides a method for automatically resetting a keypad phone connected to a key system, wherein a predetermined time and a predetermined number of times are set in a memory, and then a timer is counted and then counted by the timer. A first step of comparing a time with a set predetermined time stored in the memory; and performing a normal operation if the time counted by the timer in the first step does not exceed the set predetermined time stored in the memory And if the time counted by the timer exceeds the set predetermined time stored in the memory, clearing the timer and checking whether the abnormal operation executed by the keypad phone is completed. If the abnormal operation of the keypad phone is not completed in step A third step of counting the number of counts by driving a counter, clearing the counter and repeating each step when the abnormal operation of the keypad is completed; and the number counted by the counter is stored in the memory. And a fourth step of resetting the keypad phone when the predetermined number of times is exceeded.

Other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

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

1 is a schematic block diagram of a typical typical key system, which is composed of a main device 50, a plurality of general telephones 60, 70, and a plurality of key phone telephones 100,200.

In FIG. 1, the main device 50 controls the overall operation of the plurality of general telephones 60 and 70 and the plurality of key phone telephones 100 and 200 connected to the key system, and the plurality of general telephones 60 and 70 and the plurality of general telephones. The two phone phones 100 and 200 may talk to each other based on control signals of the main device 50 and the connected door main device 50, and may process various programmed functions.

On the other hand, the constituent members of the key phone for the automatic reset method of the key phone according to the present invention is a plurality of key phone telephones (100,200) shown in Figure 1 is composed of substantially the same component, the same operation process Therefore, in order to avoid duplicate descriptions, an operation procedure of an automatic reset method of one key phone telephone 100 will be described herein.

2 is a schematic block diagram of a key phone for executing an automatic reset method of a key phone according to the present invention, and includes a transceiver 110, a memory 120, a microcomputer 130, a timer 140, and a counter. It consists of 150.

2, the transceiver 110 is connected to the main device 50 to transmit and receive control signals and messages between the main device 50 and the keypad phone 100, the memory 130 performs the overall operation of the keypad phone And a predetermined time and a predetermined number of times.

The microcomputer 130 controls the overall operation of the key phone 100 using a program stored in the memory 120. In particular, the microcomputer 130 drives the timer 140 to count the time counted by the timer 140. The control signal for clearing is generated by the timer 140 and the counter 150 is driven when the number of times counted by the counter 150 is stored in the memory 120. When the number of times is exceeded, a control signal for resetting the keypad phone 100 is generated.

In addition, the timer 140 is driven by the control signal for driving from the microcomputer 130 and counts the time, and the counter 150 is driven based on the control signal for driving from the microcomputer 130 and counts the number of times. Count.

An operation process of the automatic reset method of the key-phone telephone having the above-described member will be described in more detail with reference to FIGS. 2 and 3.

First, the memory 120 stores a predetermined time and a predetermined number of times set by an operator (step 310).

Next, the microcomputer 130 generates a control signal for driving the timer 140 to the timer 140, and the timer 140 is driven based on the control signal for driving from the microcomputer 130 to time. Is counted (step 315).

In addition, the microcomputer 130 compares the time counted by the timer 140 with a predetermined time stored in the memory 120 (step 320), and the time counted by the timer 140 is stored in the memory 120. If the stored preset time is not exceeded, the normal routine is processed (step 325), and if the time counted in the timer 140 exceeds the preset time stored in the memory 120, the microcomputer 130 generates a timer. A control signal for clearing 140 is generated, and the timer 140 is cleared based on the control signal for clearing from the microcomputer 1300 (step 330).

Next, the microcomputer 130 checks the work performed by the phone phone 100 (step 335), and generates a control signal for driving the counter 150 when the phone phone 100 executes an abnormal work. The counter 150 is driven based on a control signal for driving from the microcomputer 130.

In addition, the microcomputer 130 compares the number of times counted by the counter 150 with a predetermined number of times stored in the memory 120 (step 350), and the number of times counted by the counter 150 is stored in the memory 120. If less than the predetermined number of times stored, the process returns to step 315 and repeats the steps 320, 330, 335, and 345.

On the other hand, as a result of the check in step 335, when the abnormal operation of the key phone 100 is completed, the microcomputer 130 generates a control signal for clearing the counter 150, and clears from the microcomputer 130 The counter 150 is cleared based on the control signal for the control (step 340).

On the other hand, if the number of times counted in the counter 150 exceeds the predetermined number of times stored in the memory 120 as a result of the check in step 350, the microcomputer 130 generates a control signal for resetting the key phone telephone 100. Is generated and executed again from the beginning of the program stored in the memory 120 based on the control signal for resetting from the microcomputer 130. In other words, the key phone is initialized (step 335).

As described above, when the keypad 140 is executing abnormal work while the timer 140 is driven and the time is counted based on the control signal of the microcomputer 130, the control unit of the microcomputer 130 controls the system. When the number of times that the counter 150 is driven and counted exceeds a predetermined number of times stored in the memory 120, the counter 150 is executed again from the beginning of the program stored in the memory 120 based on the control signal of the microcomputer 130.

Therefore, by using the present invention, when the key phone is abnormally operated, the key phone is automatically reset without an operator's manual operation, so that the key phone can be operated more conveniently.
