[Industrial use]

The present invention relates to a failure monitoring apparatus and a failure monitoring method of a computer, and more particularly, to monitor the status of an unmanned automated facility including a personal computer and a computer device, and to transmit the failure details to a host computer through a normal telephone line. It relates to a failure monitoring device and a failure monitoring method of a computer.

[Prior art]

In recent years, as the use of computers has become common, unmanned automation facilities that install only a device controlled by a computer have been generalized without arranging manpower at various convenience facilities. Examples of such facilities that are currently put into practical use include unmanned automated corners of banks, cash machines such as subway stations, convenience stores with only vending machines, and unmanned method systems using computer-controlled shutters. The scope of application of the facility is expected to increase significantly.

Such unmanned automation facilities should generally be managed by one host computer. In other words, if such an unattended automation facility fails and fails to function, or if a third party misuses or destroys the automated facility, the host computer is notified of the failure, and the host computer heals itself or needs it. In such cases, alarm signals should be generated so that personnel can repair the unmanned automation facility. In order to enable communication between the unmanned automation facility and the host computer, a dedicated line for communication is currently installed between the unmanned automation facility and the host computer, or a modem is installed between the unmanned automation facility and the host computer to use a telephone line to connect the two devices. The method of communication is used.

However, installing a leased line between an unmanned automation facility and a host computer has a disadvantage in that a large amount of unmanned automation facilities and a large distance from the host computer are expensive to install a leased line. In the case of installing a conventional telephone line, it is not necessary to install a dedicated line, but it is disadvantageous that the cost is not small because a modem must be installed in all the devices for communication.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an apparatus for monitoring a failure of a computer that enables communication between an unmanned automated facility and a host computer using a telephone line.

It is still another object of the present invention to provide a fault monitoring system of a computer that can simply transmit a fault content of an unmanned automated facility to a host computer.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. 1 is a functional block diagram of an apparatus for monitoring a failure of a computer according to an embodiment of the present invention, and FIG. 2 is an operation flowchart of the apparatus for monitoring a failure of a computer according to an embodiment of the present invention.

As illustrated in FIG. 1, the apparatus for monitoring a failure of the present invention includes an input port 20 and an input port 20 for receiving an electrical signal corresponding to an operation state from an unmanned automated facility that is a monitoring target device 10. And a central processing unit 30 for processing the input signal. The CPU 30 includes an oscillator 40 for generating a clock signal to operate the CPU 30, a reset signal generator 50 for resetting the CPU 30, and the fault monitoring device. Is connected to a memory 60 in which an operation program of the program is recorded. As the memory 60, it is preferable to use an EEPROM capable of recording a program in the memory and electrically reading and using the recorded program or data or changing memory information. In addition, the power supply unit 70 is connected to the central processing unit 30 to supply power to the central processing unit 30.

In the memory 60, for example, a program for causing the failure monitoring apparatus to perform the following function is stored. First, the central processing unit 30 monitors the program monitoring signal output from the monitoring target device 10 to monitor whether the program of the unmanned automation facility is down. That is, when there is no signal for a specific time from the monitoring target device 10, for example, if no signal for 10 seconds does not come, the program processing is processed by the central processing unit 30 through the output relay 80 to monitor the device ( 10) Send reset signal to unmanned automation facility. Send the reset signal once to check if the program is running. If the signal still does not come, the CPU 30 generates a dialing signal through the DTMF signal transmitter 90, and the circuit with the signal corresponding to the program error. Send to the controller 100. The DTMF signal transmitter 90 refers to a dual tone multifrequency signal transmitter, and is a device for dialing a combination of tones of two frequencies. The DTMF signal transmitter 90 generates a pulse signal corresponding to each obstacle of the unmanned automation facility, which is the monitoring target device 10, together with the dialing signal for making a call to the host computer 120, and then the circuit controller 100. Send through). Then, the dialing signal for making a call to the host computer 120 is transmitted through a general telephone line or other trunk line or extension, so that the fault monitoring apparatus of the present invention and the host computer 120 are connected through a normal telephone line. After being connected to 120, a pulse signal corresponding to the fault content is subsequently transmitted to the host computer 120. At this time, the selection of the trunk line and the extension line is made by the central processing unit 30. When the pulse signal of the fault content is completely transmitted through the process, the central processing unit 30 stops transmitting the signal.

Second, the CPU 30 senses the power output from the monitoring target device 10 and determines that the power is down when no voltage is detected, and transmits a signal corresponding to the power down to the DTMF signal transmitter 90. Send to). Third, the CPU 30 detects a signal output from the monitoring target device 10 and monitors whether or not the capacity of the hard disk is saturated, and transmits the corresponding signal to the DTMF signal transmitter 90 when saturated. send. As described above, the signal detected by the fault monitoring apparatus of the present invention is not limited to the above-described power monitoring signal and program monitoring signal, and various sensor detection signals and the like may be detected and processed by appropriately changing a program in the memory 60. .

The host computer 120, which is a monitoring computer, is provided with means for decoding the pulse signal input from the fault monitoring apparatus. The host computer 120 displays the fault contents transmitted from the fault monitoring apparatus and stores and prints the fault contents on the hard disk. The user can know the trouble of the unmanned automation facility by the display content of the host computer 120. In addition, the host computer 120 may transmit a signal for controlling or resetting the power of the monitoring target device 10 by outputting a control signal to the DTMF signal inputter 110 through the trunk line and the extension. As such, when the control command is received from the host computer 120, the CPU 30 outputs a control signal corresponding to the control signal to the output relay 80, and the output relay 80 outputs the monitoring target device 10 according to the signal. Or control the operation of other peripherals. Examples of control signals output from the output relay 80 may include a power control signal, a device on / off signal, a lamp on / off signal, a motor control signal, an illumination control signal, and the like. By changing the program contents of 60), it is possible to generate various control signals that can protect or repair an unmanned automation facility, such as controlling motors, shutters, and other controllers.

The fault monitoring device of the present invention is preferably configured as a separate device to be electrically connected to the unmanned automation facility, the LED is installed on the outside to inform that the fault monitoring device is currently operating, or the fault monitoring device is a host It may be displayed to indicate that the computer 120 is in a call.

Next, the operation of the failure monitoring apparatus of the computer of the present invention will be described with reference to FIG.

First, when power is supplied to the central processing unit 30 of the failure monitoring apparatus by the power supply unit 70, the failure monitoring apparatus enters the failure detection mode (S10). When the failure monitoring apparatus is in the failure detection mode, when a failure of the monitoring target device 10 is detected (S20), the CPU 30 determines the failure details (S30).

The central processing unit 30 controls the DTMF signal transmitter 90 so that the DTMF signal transmitter 90 generates a dialing signal and a pulse signal corresponding to each obstacle of the unmanned automation facility, which is the monitoring target device 10, The DTMF signal transmitter 90 generates a pulse signal corresponding to the dialing signal and the trouble content and transmits it through the line controller 100. Then, a pulse signal for making a call to the host computer is transmitted through a general telephone line or other trunk line (S40), and at this time, the fault monitoring apparatus and the host computer 120 of the present invention are connected through a normal telephone line. After connecting to the host computer (S50), the pulse signal corresponding to the fault content is subsequently transmitted to the host computer (S60). When the pulse signal related to the disturbance is completely transmitted through the above process (S70), the CPU 30 stops the transmission.

In addition, the host computer 120 may also send a control signal to the circuit controller 100 using a trunk line or an extension line, and the central processing unit 30 may process the pulse signal sent by the DTMF signal input unit 110. It is converted into a signal that can be used to control the monitoring target device 10 or various peripherals.

In the case of using the fault monitoring device and fault monitoring method of the computer of the present invention, it is not only necessary to install a dedicated line for communication for communication between the monitored device and the host computer, but also a modem in each monitored device and the host computer. There is no need to install a device, which lowers the cost of the equipment and allows for easy communication between the monitored device and the host computer.
