Description

  The present invention relates to a monitoring system, a monitoring device, a monitoring terminal, and computer software, and particularly relates to a technique for monitoring water supply and distribution of water and sewage, industrial production equipment, sales data collection equipment, and the like.

  Conventionally, a system in which a monitoring terminal and a monitoring device communicate to monitor equipment is known. As an example of a conventional monitoring system, there is Patent Document 1 or the like.

  In the conventional monitoring system shown above, for example, when monitoring what is called a manhole pump for draining sewage, monitoring is performed to accurately monitor the facilities where manholes are installed. Equipment installation work is performed.

  When the monitoring terminal installed in the manhole control panel on the site side and the central monitoring center etc. Therefore, it is necessary to perform an initial setting operation including a communication function and communication operation, a test operation operation, or an initial operation confirmation operation so that monitoring or control can be performed as specified.

  Conventionally, in order to start the operation of such a monitoring system, there has been a problem that the amount of work during the trial operation is very large and the cost for constructing the monitoring system has been increased.

  Conventionally, during the test operation of the monitoring system, setting data almost identical to the setting data of the monitoring terminal on the machine station side is also set in the monitoring device on the upper side. In addition, since the monitoring terminal and the monitoring device operator are usually different persons in charge, these setting data are input by individual input operations. For this reason, the work man-hours for inputting the setting data were required twice.

  Moreover, since both data were input by the operator's manual work, it was necessary to confirm at the time of a trial run whether there was any mistake in those data inputs.

In the conventional monitoring system, since the communication means is a method unique to the monitoring system, it is difficult to communicate with a general-purpose computer. Therefore, it is necessary to prepare a dedicated data input device at the time of trial operation, and it is necessary to prepare a dedicated data input device and an operator who masters the operation when performing the test operation.
Japanese Patent Laid-Open No. 11-361237

The above conventional problems are summarized as follows.
(1) The work man-hours for creating the conversion table (monitoring device setting file) are large. The numerical data used for communication between the monitoring terminal and the monitoring device is converted into signal names, signal analog values, and contact signal on / off values. Therefore, it is necessary to create a conversion table (monitoring device setting file) in the monitoring device. The number of work steps for creating this conversion table is large, and when a monitoring device is newly introduced, the monitoring device becomes expensive. For this reason, it has become an obstacle for introducing a monitoring device. In addition, in order to create the conversion table for the monitoring device, specialized knowledge about the monitoring device is required, and thus an expert has to work. This also causes an increase in cost for creating the conversion table.

(2) Large work man-hours during test operation Conventionally, the man-hours during test operation of the monitoring device were large. Factors for increasing the number of man-hours during trial operation were as follows. (B) During the test operation, it was necessary for a specialist with specialized knowledge of the monitoring device to go to the central monitoring room where the monitoring device was installed. (B) Since the conversion table to be set in the monitoring device was created manually, it was necessary to check whether the contents were correct during the trial run. (C) It took man-hours to create a checklist for trial operation. The check list is created as a list corresponding to each signal item monitored by the monitoring device, and is created by manually confirming a number of items.

(3) The need for trial operation when changing or adding monitoring equipment After a while, the equipment of the equipment to be monitored is often changed or the number of equipment is increased. Conventionally, even if it is a small change or expansion, it is necessary to change the setting of the conversion table of the monitoring device, etc., so it is necessary for an expert to go to the central monitoring room to perform trial operation work, which is a cause of high cost It was.

In light of the above problems, the present invention intends to respond as follows.
(1) The conversion device automatically creates a conversion table. The monitoring device takes in the setting data set in the monitoring terminal, and the numerical data used for communication between the monitoring terminal and the monitoring device is converted into the signal name, the analog value of the signal, A conversion table for converting and displaying contact signal ON / OFF values is automatically created. The monitoring device can communicate with the monitoring terminal by setting the communication condition to the standard state in advance even after the start of the trial run and before making a special setting. Under standard communication conditions, the monitoring device communicates with the monitoring terminal, and the setting data set in the monitoring terminal is automatically captured. By automatically importing the setting data in the monitoring terminal, it is necessary to take the procedure of first testing the monitoring terminal on the site side, then connecting the site and the center with a communication line, and testing the entire monitoring system. Rather, if the monitoring terminal is trial run on the site side, then it is possible to automatically test the entire monitoring system by connecting the site and the center with a communication line. Setting data created by a single test run on the monitoring terminal is also automatically used on the monitoring device side.

  With the above operation, it is possible to reduce the man-hours for creating the conversion table during the trial run. In addition, since the conversion table is automatically created, rework due to an input error can be reduced as compared with the case where the conversion table is manually created. Further, only one setting data creation work on the site side that is the basis of the conversion table is a substantially necessary work. This method requires only the work of inputting the setting data into the monitoring terminal while accurately confirming the name of the signal at the site and the type of signal, and adopting the test operation result as a positive one in the monitoring device Is reasonable.

(2) Create a conversion table and a check list at the time of test run by automatically creating them without specialized knowledge so that the test run can be performed.
During the test operation, the operator of the monitoring device sets the telephone number of the monitoring terminal on the monitoring device before the setting data in the monitoring terminal is taken into the monitoring device. As a result, the monitoring device communicates with the monitoring terminal designated by the telephone number, takes in the setting data in the monitoring terminal, and automatically creates a conversion table. Thereafter, the monitoring apparatus automatically creates a check list for the trial run using the information in the conversion table. These operations can reduce the number of test run man-hours.

  Here, the telephone number is a communication condition that is generally easy to understand. If communication is possible by setting only the telephone number, specialized knowledge about the inside of the monitoring device is not required when the monitoring device is trial run. In addition, since the monitoring device automatically creates a test run check list, it is possible to accurately instruct the content of the test run even for an operator who is not familiar with the test run work.

(3) When the monitoring equipment is changed or added, the monitoring device automatically creates a conversion table, eliminating the need for a trial run by an expert.
The change and addition of the conversion table can also be executed by the operation of the monitoring device by setting the telephone number of the monitoring terminal. This eliminates the need for an expert to visit the central monitoring room for monitoring in response to minor changes in the monitoring system (facility changes, addition of monitoring terminals). Thereby, since it is possible to change the setting of the monitoring device in response to the change of the monitoring system without specialized knowledge, the cost required for the maintenance and management of the monitoring system can be reduced.

  That is, the present invention includes a monitoring terminal that transmits monitoring data of equipment to be monitored, a communication control unit, a storage unit, a display unit, an input unit, and a control unit, and receives and displays monitoring data from the monitoring terminal. A monitoring system including a device that receives setting data used for conversion of the monitoring data when the monitoring data is displayed from the monitoring terminal and stores the setting data in the storage unit. .

  Further, the present invention is a monitoring device comprising a communication means, a storage device for storing a communication program, and a CPU for executing the communication program, wherein setting data from a monitoring terminal for transmitting monitoring data of the facility to be monitored is received. Receiving and storing in the storage device, and using the setting data stored in the storage device, the numerical data transmitted by the monitoring terminal is converted into a signal name, signal analog numerical value, and contact signal ON / OFF value for display A monitoring device having means for

  And this invention is a monitoring apparatus which has a means to transmit / receive with the said monitoring terminal using the input data which the operator input, and to create a check list at the time of a test run.

  Furthermore, the present invention is a monitoring terminal that transmits monitoring data of a facility to be monitored to a monitoring device that receives and displays the monitoring data, and is used to convert the monitoring data when the monitoring device displays the monitoring data. A monitoring terminal having means for transmitting setting data to be transmitted to the monitoring device.

  Further, the present invention is computer software used in a monitoring device comprising a communication means, a storage device that stores a communication program, and a CPU that executes the communication program, and transmits monitoring data of the equipment to be monitored. Function for receiving setting data from the monitoring terminal and storing it in the storage device, and using the setting data stored in the storage device, the numerical data transmitted by the monitoring terminal is converted into the signal name, the analog value of the signal, and the contact It is computer software comprising a program that causes a computer to realize a function of converting and displaying a signal on / off value.

  According to the present invention, it is possible to obtain a monitoring system, a monitoring device, and a monitoring terminal that reduce the work man-hours of an operator and do not require specialized knowledge.

The best mode for carrying out the present invention will be described.
An embodiment of a monitoring system, a monitoring apparatus, and a monitoring terminal according to the present invention will be described with reference to the drawings. FIG. 1 is an explanatory diagram of the overall configuration of the monitoring system. The monitoring system includes at least monitoring terminals 140 to 144 and a monitoring device 111. The monitoring device 111 installed in the monitoring room uses the modem 112 and communicates with the monitoring terminals 140 to 144 via the LAN or telephone line 130 to monitor the operating state of the equipment to be monitored. There are three basic functions of this monitoring system. The first is to display real-time data of the monitored equipment on the screen of the monitoring device 111. Second, if there is a failure in the equipment of the monitoring targets 140 to 144, the monitoring device 111 sends an alarm mail to notify the equipment manager of the failure. Thirdly, the monitoring device 111 collects and stores the operation records stored in the monitoring terminals 140 to 144.

  The monitoring device 111 has a function of collecting and storing data in the monitoring terminals 140 to 144 while assisting the monitoring room and the monitoring terminals 140 to 144 to communicate with each other. The personal computers 100, 101, and 110 display data in the monitoring device 111. The personal computer 110 in the monitoring room displays data stored in the monitoring device 111 via the LAN. Even if the personal computers 100 and 101 are outside the monitoring room, they can display data stored in the monitoring device 111 via the network.

  Even if the monitoring terminals 140 to 144 do not use the function of the monitoring device, the monitoring terminals 140 to 144 are functions of only the monitoring terminal and have a minimum function for monitoring the equipment to be monitored. That is, when a failure occurs, the monitoring terminals 140 to 144 are connected to the mail server 151 and a function for reporting an alarm to the alarm notification destination telephone 102 and notify the mobile phone 150 by an alarm mail. With this function, when there is an abnormality in the monitoring target facility, the facility administrator can notice the abnormality in a short time, go to the facility, perform maintenance, and can maintain and manage the facility.

  In a simple system, there is a case where the system is formed only by the monitoring terminals 140 to 144, the voice report destination 102, and the mobile phone 150 without the monitoring device 111.

  Since the monitoring terminals 140 to 144 have a function of operating without the monitoring device 111, the monitoring terminals 140 to 144 store data for expressing the state of the monitoring target facility by voice or mail.

  2A and 2B are block diagrams of the monitoring terminal 140 (to 144) and the monitoring device 111. FIG. The control unit 148 of the monitoring terminal is a device that executes the program of the monitoring terminal, and operates the functions of the facility monitoring unit 145, the storage unit 146, and the communication control unit 147. The equipment monitoring unit 145 inputs an operation signal of the equipment to be monitored. The storage unit 146 is a device for recording the signal input from the facility monitoring unit 145 by the program operation by the control unit 148 and storing the recorded contents. The communication control unit 147 is connected to a communication line such as a telephone line, and communicates with various higher-level devices such as a monitoring device, a telephone, and a mail server.

  The control unit 125 of the monitoring device 111 is a device that executes a program of the monitoring device, and operates the functions of the communication control unit 121, the storage unit 122, the display unit 123, and the input unit 124. The communication control unit 121 is connected to the LAN in the monitoring room to communicate with the personal computer 110 and the monitoring terminal 140, and controls the modem 112 to connect to the communication line 130 to which the monitoring terminals 141 to 144 are connected. Communicate with. The display unit 123 is a personal computer connected via the CRT of the monitoring apparatus main body or the LAN, and is a device that displays data inside the monitoring apparatus. The input unit 124 is an input device such as a keyboard and a mouse of the monitoring device main body, or an input device such as a keyboard and a mouse of a personal computer connected via a LAN. The monitoring device 111 operates as a server, displays an operation record of the monitoring target facility stored in the monitoring device on a personal computer or the display unit 123, and communicates with the monitoring terminals 141 to 1444 using the modem 112. The current value of the monitoring target equipment is displayed online, or the alarm data transmitted from the monitoring terminals 140 to 144 is displayed.

  FIG. 3 shows an example of a telephone number list. The list of telephone numbers of the monitoring terminals 1 to N is input by the operator operating the monitoring device 111 and stored in the monitoring device. This list is created when the monitoring system is operated for the first time, or when the change of the system configuration is reflected in the monitoring device 111.

  When the operator manually inputs the telephone numbers of the monitoring terminals 140 to 144 and operates the monitoring device 111, the monitoring device communicates with the individual monitoring terminals 140 to 144 and is stored in the monitoring terminal. Read the initial setting data. The monitoring device 111 operates the monitoring system using these initial setting data.

  In this example, the telephone number is designated and the monitoring device 111 is set to communicate with the monitoring terminals 140 to 144. However, the telephone number is not limited depending on the communication line 130 used. For example, in a communication line such as a LAN, since the monitoring device 111 can identify the monitoring terminals 140 to 144 not by a telephone number but by an IP address, an IP address can be used on such a line instead of a telephone number.

  4 and 5 show examples of the initial setting data stored in the monitoring terminal. FIG. 4 is a table of contact data initial setting data monitored by the monitoring terminals 140 to 144. FIG. 5 is a chart of initial setting data of analog data. The initial setting data of the contact data in FIG. 4 indicates what data is the contact signal connected to the monitoring terminals 140 to 144. For example, if the contact name signal with the device name “No. 1 pump operation” in this chart is ON, it means “No. 1 pump is operating”. Similarly, if the “No. 1 pump failure” signal is ON, It means that one pump has failed. In FIG. 5, for example, it means how an analog signal indicating “water level” can be interpreted. That is, if the maximum value of the analog signal is input, it means that it can be interpreted as a water level of 5 m indicated by a span. If the minimum value of the analog signal is input, it can be interpreted as a water level of 0 m indicated by a span. Further, the unit of the signal is m, the range that the analog signal can take is 0 to 5 m, the upper limit set value is 3.5 m, and the lower limit set value is 0 m. When an analog value exceeding the upper limit is input and when an analog value lower than the lower limit is input, it indicates that the monitoring terminals 140 to 144 report as alarms.

  Further, the signal address and bit in FIG. 4 indicate where the data is input in the signal allocation of the monitoring terminal. That is, “No. 1 pump operation” is connected to the contact signal of bit 0 of WR0000, and “No. 1 pump failure” indicates that it is connected to the contact signal of bit 1 of WR0000. FIG. 9 shows an example of a specific wiring state of these assignments.

  Similarly, the signal address in FIG. 5 indicates where the analog signal is input to the monitoring terminals 140 to 144. An example of a specific wiring state of this assignment is shown in FIG.

  The initial setting data as shown in FIGS. 4 and 5 is conventionally set in the monitoring terminals 140 to 144 and individually in the monitoring device 111. In the present invention, when the initial setting data of the monitoring terminals 140 to 144 is stored and the telephone number of the monitoring terminal 111 is set in the monitoring apparatus 111, the monitoring apparatus 111 monitors the monitoring terminals 140 to 144 based on the set telephone number. , And automatically acquire these data from the monitoring terminals 140 to 144 and use them for the operation of the monitoring device 111.

  Furthermore, since the monitoring terminals 140 to 144 have an alarm notification function, the monitoring terminals 140 to 144 also have initial setting data regarding the content of the alarm notification. FIG. 13 shows an example of the alarm notification initial setting data. In FIG. 13, a range 1000 is the initial setting data of the contact data and the analog data described above, and a range 1001 is the initial setting data indicating the means for alarm notification.

  6 to 8 show examples of contents displayed on the screen of the monitoring apparatus using these initial setting data. These are screens showing the current value of the operating state of the monitoring target equipment on the monitoring terminal side through communication between the monitoring device and the monitoring terminal. FIG. 6 is a flow chart of equipment to be monitored displayed on the screen. The flow diagram shows the relationship between the individual devices of the facility. FIG. 7 shows an example of the current value of the contact signal in the contact list. Here, “No. 1 pump operation” is a signal input to bit 0 of the signal address WR0000, and indicates that the signal is currently ON (the No. 1 pump is operating). No. It indicates that the contact signal from 1 pump failure to 200V power failure is OFF.

  FIG. 8 shows an example in which the current value of the analog signal is displayed on the screen. It indicates that the water level is a signal from the signal address WR0000, and that the current value of the signal is 4.7 m.

  FIG. 9 shows an example of how contact signals and analog signals are specifically wired on the monitoring terminal side. The monitoring device 600 is in the center and communicates with the monitoring terminal via a telephone line 601. The monitoring terminal includes a communication unit 603 and an I / O unit 607. The communication unit includes a CPU, a memory, and a program for communicating with the monitoring device 600, and has a function of temporarily recording and storing an operation state to be monitored. The communication unit 603 also has a program for notifying the alarm when the alarm signal in the contact signal is turned ON and when the analog signal exceeds the upper and lower limits.

  The I / O unit 607 is a device for taking in contact signals and analog signals. In FIG. The one pump operation signal indicates a state in which it is connected to the I / O unit 607 as a contact signal for turning on and off. Signal addresses and bits are determined in the order of connection to the I / O unit 607. That is, the contact signal (No. 1 pump signal) 608 connected to the 0th terminal and the 24V terminal of the I / O unit 607 in FIG. 9 is input as bit 0 of WR0100. Similarly, a contact signal (No. 1 pump failure) 609 connected to terminals 1 and 24V is input as bit 1 of WR0100.

  Although two analog signals are input in the example of FIG. 9, the first analog signal (water level) 611 is connected between the IN1- terminal and the IN1 + terminal and input to the signal address of WR0000. The analog signal (No. 1 pump signal) 612 connected to the second terminal is input to the address of WR0001.

  FIGS. 10 and 11 show how the monitoring apparatus 701 and the monitoring terminals 704 to 706 communicate after the monitoring apparatus 701 acquires the initial setting file from the monitoring terminals 704 to 706.

  When the monitoring device communicates with the monitoring terminal, the specific signal names such as “No. 1 pump operation”, “ON”, “water level”, and “4.7 m”, and the physical quantity itself are not sent to the communication line. Communication is performed as alphanumeric data as in this embodiment. This is because it is converted into data to reduce the communication volume, increase the communication speed, lower the communication cost, and communicate in the form of alphanumeric data (binary data) that can be easily processed as computer data.

  In FIG. 10, the monitoring device 701 inquires the monitoring terminals 704 to 706 to transmit data representing the current value. Here, an inquiry “ftp 192.168.10.10...” Is executed. In response to this, the monitoring terminals 704 to 706 respond with a response file “WR0000 0F10...”. With such data exchange, the current value of the monitoring target equipment on the monitoring terminals 704 to 706 side is transmitted to the monitoring device 701.

  FIG. 11 shows this electronic message in detail. The inquiry message transmitted from the monitoring device 701 to the monitoring terminals 704 to 706 is sent from the monitoring terminal 701 to the instant. Request (inquire) to send a file called dat. instant. dat is a file in the monitoring terminals 704 to 706 and is a file indicating the current value of the monitoring target.

  An example of details of response file data transmitted as responses from the monitoring terminals 704 to 706 is shown in the lower half of FIG.

  FIG. 12 shows an example of how to interpret these data. In the example of this table, analog data is allocated to WR0000 to WR0002. The value of WR0000 is 0000111100010000 in binary values and 0F10 in hexadecimal. Since analog data is a value resulting from AD conversion with 12 bits, the minimum value is in the range of 0000 in hexadecimal and the maximum value is in the range of 0FFF. Further, when taking the maximum value of 0FFF from the setting relating to the water level of the initial setting data shown in FIG. 5, the water level is interpreted as 5 m. Therefore, when the data is OF10, 0F10 ÷ 0FFF × 5 = 4.7, and the current value of the water level is 4.7 m. This calculation is performed on the monitoring device 701 side, and the water level is displayed as 4.7 m in the display column of the current value.

  The digital data area is WR0100 to WR0102 in the example of this chart. In FIG. The signal for 1 pump operation was set to be the 0th bit of WR0100. The current value in FIG. 12 is No. 1 because bit 0 of WR0100 is 1. One pump is interpreted as operating. As a result, the monitoring apparatus 701 displays the current value in the display column No. One pump operation is displayed as ON.

  As described above, the monitoring device 701 displays the current value from the data acquired through communication and the initial setting data.

  FIG. 13 shows an example of a check list executed for the trial run. The monitoring device automatically outputs this test run checklist from the initial setting data. The range of the chart is indicated by 1000, 1001, and 1002 below the chart. A range 1000 in the table is digital and analog initial setting data. A range 1001 in the chart is initial setting data indicating the contents of the alarm notification. A range 1002 in the chart is a column for checking whether or not the operation has been successfully performed during the test run, and is a column for the operator performing the test run to manually input. This test run checklist is created for each monitoring terminal.

  During the test run, the signal is actually input to the monitoring terminal, and as a result of communication between the monitoring terminal and the monitoring device, whether the current value is correctly displayed on the monitoring device, whether an alarm report is implemented, or an alarm report is issued. Check whether the content is correct. A test operator for inputting a signal goes to the monitoring terminal side, and a test signal is written (input) to the monitoring terminal according to the order of the test operation checklist.

  The test operator on the monitoring terminal side inputs a simulated analog signal corresponding to the maximum, minimum and specific values of the water level to an analog terminal for inputting the water level. As a result, the other test operator on the monitoring device confirms whether the value is correctly displayed on the monitoring device. In addition, when the upper limit and lower limit values are exceeded, a test run is performed to determine whether the alarm notification is performed according to the alarm notification setting. In this example, the report destination is the default (standard report destination that reports when a report destination is not set specially), and confirms whether voice notification and email notification are performed. If the operation is correct as a result of the above test run, the test runner enters a circle in the column of the range 1002 of the chart.

  The test operation of the contact signal is performed in the same way. The test operator on the monitoring terminal side inputs a temporary contact signal to bit 0 of WR0100 and communicates. Check whether it was implemented and enter the result.

  FIG. 14 is used to explain how the efficiency of the trial run has changed as a result of the present invention. The trial operation of the monitoring system is divided into a trial operation on the monitoring terminal side and a trial operation of the monitoring device.

  In the trial operation of the monitoring terminal, work is performed in the order of 1 to 7 in this chart. 1. Create setting data to operate the monitoring terminal. The setting data includes the telephone number of the report destination, signal name, signal address, alarm status, analog span, analog unit, and the like. 2. Create a commissioning checklist. 3. A monitoring terminal and a setting device for writing setting data to the monitoring terminal are connected. 4). Write the setting data to the monitoring terminal. 5). A temporary signal is input to the monitoring terminal. 6). Check the operation of the monitoring terminal. 7). Create a commissioning report. In the present invention, the trial operation of the monitoring terminal is conventional. In both the prior art and the present invention, the trial operation of the monitoring terminal is carried out by a service person who has been trained in how to operate the monitoring terminal. Since the monitoring terminal can operate independently without a monitoring device, the test run is also performed independently.

  When the test operation on the monitoring terminal side is completed, the test operation on the monitoring device side is performed. The test operation procedure is shown in FIGS. 8). Conventionally, the setting data on the monitoring device side is created by a monitoring device software expert. In contrast, in the present invention, when the telephone number of the monitoring terminal is input to the monitoring device in a list format, the monitoring device automatically communicates with the monitoring terminal and collects setting data stored in the monitoring terminal. come. The collected data is also used as setting data for the monitoring device. The setting data stored in the monitoring terminal has been confirmed by performing a trial run and can be used as it is in the monitoring device. 9. The trial run checklist has been created manually by software experts according to the setting data of the monitoring device, but in the present invention, the monitoring device is based on the data collected from the monitoring terminal. Create automatically. 10. Conventionally, the setting of the communication conditions with the monitoring terminal has been manually set for the monitoring device by a software expert. However, in the present invention, the monitoring device automatically sets based on the telephone number list. As shown in the telephone number list of Table 1, the telephone number is manually set in the monitoring device for each monitoring terminal. The monitoring terminal can communicate with the default IP address before communicating with the monitoring device, but the monitoring device automatically assigns a different IP address to each monitoring terminal. By using a different IP address for each monitoring terminal, communication using a communication device such as a router becomes possible. When a router is not used, it is not necessary to set the IP address separately. The monitoring apparatus automatically performs such communication condition setting work. 11. 11. Input of signals to the monitoring terminal 12. Confirmation of the operation Report creation is not automatic and is done as usual.

  11. To 13. However, according to the present invention, it is not necessary to perform the monitoring operation of the monitoring device. In the present invention, the monitoring operation is not necessary. Since the test run of the apparatus can be performed by only two servicemen, the cost of the test run of the monitoring apparatus is reduced, and the range of workers capable of performing the test run is increased, so that the efficiency of the trial run work is improved. Furthermore, since the work procedures 8 to 10 are automated, the number of test operation man-hours is reduced, and the cost of the test operation occupying a large weight in the cost for constructing the monitoring system is reduced. As a result, the cost of the monitoring system can be reduced.

  In addition, since operations 8 to 10 that have been performed manually are automatically performed, manual rework due to operational errors can be reduced, and the efficiency of trial operation can be improved.

  In addition, the monitoring system may increase the number of monitoring terminals every normal year, but at such times, the number of man-hours for requesting software specialists to set monitoring devices every year was large. Depending on the year, the setting on the monitoring device side could not be changed. According to the present invention, since the setting change and the trial operation of the monitoring device can be performed only by the service person, it is possible to reduce the burden of adding monitoring terminals every year.

  Although the monitoring device has been described in the above embodiment, the computer software used in the monitoring device includes a communication unit, a storage device that stores the communication program, and a CPU that executes the communication program. The function of receiving the setting data from the monitoring terminal that transmits the monitoring data of the equipment to be stored and storing it in the storage device, and the numerical data transmitted by the monitoring terminal using the setting data stored in the storage device, the signal name By using computer software consisting of a program for causing a computer to realize the function of converting and displaying analog values of signals and ON / OFF values of contact signals, the conventional monitoring device is used as the monitoring device of the present invention. Can do.
