Figure 3 is a flow chart illustrating a method for providing a two-way abnormality diagnostic alarm of the machine according to a preferred embodiment of the present invention.

When the WDL terminal 110 has an error in a measuring sensor such as a PLC or a measuring sensor composed of several sensors or a single sensor measuring one or more of level, flow rate, pressure, temperature, humidity, gas, etc. When an abnormal state signal of the equipment is transmitted to a predetermined communication means or when an abnormality occurs in its own power source or other equipment, it generates an abnormal signal of the equipment (S300). Next, the WDL terminal 110 extracts a customized alarm message suitable for the abnormal state of the equipment or the type of the equipment from the memory unit 210 using the abnormal state signal or the generated abnormal signal received under the control of the controller 220. The final customized alarm message is generated by combining information such as identification information (equipment code, location information, etc.), custom alarm message, and time of the WDL terminal 110 (S302).

Here, the equipment abnormality includes all hardware / software abnormalities of the measurement equipment, abnormalities of the power supply unit 230, the control unit 220, and the like of the WDL terminal 110, and other abnormal states of all the connected equipment.

Even in the case of generating an abnormal signal of the above-described equipment, there are two software / hardware methods.

In the hardware method, when the WDL terminal 110 receives the error generation signal of the device from the measurement device 100 or the PLC, that is, the error generation signal is received through the hardware contact point, the WDL terminal 110 meets the previously stored error table. It is a method of searching and extracting alarm messages that match the error generating signal according to the fault condition of the equipment.

In the software method, when an abnormal signal of the equipment is transmitted from the measurement sensor, for example, the measurement sensor is a temperature sensor, and it is assumed that the normal temperature data stored in the WDL terminal 110 is 20 to 30 ° C. When the temperature data is measured from the sensor to less than 20 ℃ or more than 30 ℃ and transmitted to the WDL terminal 110, the WDL terminal 110 does not enter the normal temperature data range compared to the normal temperature data (20 ~ 30 ℃) It is a method of controlling programmatically to generate an abnormal signal of the equipment by determining and generate an alarm message according to the generated abnormal signal.

Subsequently, the WDL terminal 110 uses the communication module to receive the last personalized alarm message generated in step S302 and the received telephone number (MIN) and the IP address of the manager (the management system 132 or the mobile communication terminal 134) previously stored. Through the communication network 120 is transmitted to a predetermined external management system 132 or mobile communication terminal 134 (S304).

After transmitting the customized alarm message to the external management system 132 or the mobile communication terminal 134 through the communication network 120 in step S304, the steady state from the measurement equipment 100 is periodically connected to the mechanical equipment or device It is determined whether a signal, that is, a signal indicating that the equipment abnormality is solved, is received, and the WDL terminal 110 diagnoses a power failure or other equipment abnormality by itself and determines whether the equipment abnormality exists (S306). If it is determined in step S306 that a steady state signal is not received from the measurement equipment, or if it is determined that the equipment abnormality still exists as a result of the self-device diagnosis of the WDL terminal 110, that is, if there is no action on the abnormal condition of the equipment even after a certain period of time. In operation S308, the personalized alarm message is retransmitted to the external management system 132 or the mobile communication terminal 134 through the communication network 120. In this case, the customized alarm message to be resent may have the same content as the alarm message that was initially transmitted, but may further include information such as the time elapsed from the occurrence of the first equipment error until retransmission.

If it is determined in step S306 that the steady state signal is being received from the measurement equipment or if the WDL terminal 110 self-diagnosis results indicate that the equipment abnormality has been solved, that is, if a certain action is taken for the alarm situation, The situation termination message is transmitted to the external management system 132 or the mobile communication terminal 134 through the communication network 120 (S310).

Although FIG. 4 illustrates a customized alarm message output to the mobile communication terminal 134, the management system 132 may also output the same / different custom alarm message as the mobile communication terminal 134.

In addition, the customized alarm message output to the mobile communication terminal 134 may be configured to identify the type of the equipment and the failure parts, including the code information.

When an alarm situation occurs due to an abnormality of a machine or a device, the WDL terminal 110 may perform a voice call connection to the mobile communication terminal 134 in order to prevent the loss of a customized alarm message due to the administrator's sleeping.

The information output to the mobile communication terminal 134 is the location information of the measurement equipment 100, the type of equipment in which the error occurs, the abnormal state information, code information, such as the administrator of a machine or device installed at a certain location by looking at the customized alarm message It is configured in detail so that you know at a glance which parts and which parts have failed.

In addition, when the predetermined action is taken for the abnormal state of the equipment, the present invention has an effect of transmitting a situation end message for the abnormal state of the equipment to the external system to prevent the movement of personnel for repeated measures.

In addition, the present invention has the effect of having the safety and security of the operation of the equipment by blocking the external unspecified message or telephone connection so that only the administrator designated for the security function is accessible.

In addition, the present invention has the effect of preventing the case that the administrator does not see the alarm message due to bedtime by outputting the alarm message by voice by connecting a voice call to the manager when an alarm situation occurs due to the abnormality of the equipment at night.

In addition, the present invention generates a customized alarm message suitable for the type of equipment or the abnormal state of the equipment when an abnormal state occurs in the equipment, such as power, sensors, etc. of the mechanical equipment or device, and transmits to the external system, the administrator to the equipment abnormal state information This can save time and effort fixing equipment by quickly and accurately identifying the system.

In addition, the present invention can edit the alarm message, the equipment parameters through the message bi-directional editing interface with the external system has the effect of providing a suitable alarm message according to the abnormal state of the equipment.
