  The present invention relates to a logger that collects data related to the operating state of a monitoring target such as a heat source system including a refrigerator, a logger server that processes and stores data collected by the logger, and various data collected by the logger to a user. The present invention relates to a server device to be provided and an operation state monitoring system composed of these devices.

Conventionally, various sensors such as pressure sensors and temperature sensors are attached to heat source systems that supply cold water to semiconductor manufacturing equipment such as LSI, and the operating status of the heat source system is monitored based on various physical quantities notified from these sensors. In addition, an operating state monitoring system that effectively notifies the information on the equipment by providing this operating state to a maintenance company, a user, or the like is known.
For example, JP-A-2002-288369 (Patent Document 1) discloses the following monitoring system.

[1-1. Monitoring target and basic sensor)
In the present embodiment, the heat source system 10 to be monitored includes, for example, a plurality of refrigerators, a cooling tower, a water flow system that connects the cooling tower and the refrigerator, and the like.
The basic sensor 2 is a variety of sensors installed in each device or system constituting the heat source system 10, and detects various state quantities of the heat source system. The basic sensor 2 is, for example, a thermometer that measures the temperature of a refrigerator, cooling tower, cooling water, etc., a flow meter that detects the flow rate of the cooling water, and detects the opening and closing and opening of various valves installed in the chilled water system And various sensors.
The basic sensor 2 is connected to the A / D converter 21, the sequencer 22, and the control unit 23 of the heat source system 10. The A / D converter 21, the sequencer 22, and the control unit 23 convert the acquired physical quantity acquired by the basic sensor 2 from an analog value to a digital value and supply it to the logger 3. In this case, a plurality of basic sensors 2 are connected to the sequencer 22 and the control unit 23, and the acquired physical quantity supplied from these basic sensors 2 is processed into digital data having a predetermined bit length according to a predetermined format. And supply to the logger 3.

[1-2. About the configuration of the logger)
As shown in FIG. 2, the logger 3 includes a control device 31 that executes arithmetic processing, and a storage device (first table) that stores various tables and programs that are referred to when the control device 31 executes processing. 1 storage means) 32, a sampling data storage device 33 in which the acquired physical quantity acquired by the basic sensor 2 is stored as a digital value, and a storage device (second storage) in which the acquired physical quantity or the calculated physical quantity is stored at predetermined intervals. A storage unit 34 and a communication unit 35 for exchanging information with an external device via the Internet 100 (see FIG. 1) are provided as main components.

The storage device 32 stores, for example, a device table 321, a basic sensor table 322, an extended sensor table 323, a link table 324, an event table 325, a store table 326, and the like.
In these tables, the acquired physical quantity registration information 51 shown in FIG. 3 and the calculated physical quantity registration information 52 shown in FIG. 4 are described in a distributed manner according to the attributes of the respective information.

The acquired physical quantity registration information 51 is provided corresponding to each basic sensor 2 and includes information on the basic sensor itself, various information on the acquired physical quantity to be detected, and the like.
As shown in FIG. 3, the acquired physical quantity registration information 51 includes, for example, sampling data information, basic information, error determination information, output interval information, link information, and the like.
In the sampling data information, an address, a data error, etc. are registered. The address is information indicating an address at which the acquired physical quantity related to the registration information is written in the sampling data storage device. The data error is information for detecting an error in the data itself supplied from the above-described A / D converter 21 or the like.
Sampling data information including these pieces of information is stored in the device table 321 shown in FIG.

The basic information is information indicating the basic sensor 2 actually attached to the heat source system 10 to be monitored and the acquired physical quantity attribute detected by the basic sensor 2, in other words, the attribute indicating the acquired physical quantity attribute. Information.
For example, it consists of a sensor ID uniquely set for each basic sensor 2, the name and unit of the acquired physical quantity detected by the basic sensor 2. This basic information is stored in the basic sensor table 322 shown in FIG.

  The error determination information is information necessary to determine whether or not the acquired physical quantity is an abnormal value. For example, an upper limit value and a lower limit value that can be taken by the acquired physical quantity, and a width ( Upper limit value−lower limit value). This error determination information is stored in the event table 325 shown in FIG.

The output interval information is information indicating the timing for storing the acquired physical quantity or the calculated physical quantity in a predetermined storage area of the storage device 34 and the timing for releasing the acquired physical quantity or the calculated physical quantity to the Internet 100 shown in FIG.
By registering an optimum output interval according to the properties and characteristics of the acquired physical quantity, data storage and monitoring of operation information can be effectively realized. For example, regarding an acquired physical quantity that is drastically changed with respect to time and that is frequently required to be monitored, more detailed monitoring can be realized by setting the output interval information short. For acquired physical quantities that do not require strict monitoring, setting the output interval information longer can reduce the amount of stored data and improve communication efficiency.
Further, in the output interval information, it is possible to register not only the time interval as described above but also contents that store an average value for one day.
This output interval information is stored in the store table 326 shown in FIG.
The link information is information that associates the acquired physical quantity registration information with the calculated physical quantity registration information described later. This link information is stored in the link table 324.

As described above, the acquired physical quantity registration information 51 shown in FIG. 3 is distributed and stored in the various tables 321 to 326 in the storage device 32. Various information elements (sampling data information, basic information, etc.) are associated with each other and described in the tables 321 to 326 shown in FIG.
Further, an address (reference destination address) to be referred to in the next processing is described in the address of each table in which these various information elements are described.
The control device 31 shown in FIG. 2 reads the address of each table in accordance with the reference destination address, and executes the processing described therein, thereby one program in which a series of processing contents are written. Can be obtained, and the processing procedure can be changed very easily.

Next, the calculated physical quantity registration information 52 shown in FIG. 4 uses the acquired physical quantity detected by the basic sensor 2 to calculate a new physical quantity (the physical quantity calculated by the calculation is hereinafter referred to as “calculated physical quantity”). This is the registration information required to obtain
For example, when it is desired to detect the temperature difference between the external temperature and the internal temperature of the refrigerator of the heat source system 10, it is difficult to actually provide a basic sensor and detect such a temperature difference. Therefore, when the acquired physical quantity related to the registration information B is the internal temperature of the refrigerator, and the acquired physical quantity related to the registration information C is the external temperature of the refrigerator, an arithmetic expression for subtracting the internal temperature from the external temperature, that is, “ “001C-001B (the character string indicates a sensor ID)” is registered in the calculation rule of the calculated physical quantity registration information 52. This makes it possible to obtain a new calculated physical quantity called a temperature difference by using the internal temperature and the external temperature that are acquired physical quantities respectively detected by the existing basic sensor 2 without newly installing the basic sensor 2. It becomes possible.
Thus, by registering the calculated physical quantity registration information 52, it becomes possible to monitor a new acquired physical quantity as if the basic sensor was installed there.

The calculated physical quantity registration information 52 includes basic information, calculation rules, error determination information, output intervals, link information, and the like.
The basic information is attribute information of the calculated physical quantity, and includes, for example, a name and a unit.
The calculation rule is an arithmetic expression for calculating an arithmetic physical quantity. This basic information and calculation rule are stored in the extended sensor table 323 shown in FIG.
The error determination information, the output interval information, and the link information are the same as the information related to the acquired physical quantity registration information 51 described above, and are stored in a predetermined table.
As described above, the calculation physical quantity registration information 52 is provided, and the control device 31 executes processing in a predetermined procedure while referring to these pieces of information, whereby information related to more operating states can be obtained.
In addition, as the calculation rule, calculation physical quantity registration information that can grasp the operation state and the like in the entire heat source system, for example, calculation physical registration information in which the calculation formula of the operation efficiency of the entire heat source system is set as the calculation rule. By creating the information, it is possible to obtain information that is very effective for the operation management of the heat source system, and it is possible to realize more advanced system operation.

Returning to FIG. 2, the sampling data storage device 33 is a storage device that sequentially stores acquired physical quantities of digital values supplied from the A / D converter 21, the sequencer 22, and the control unit 23. For example, in the present embodiment, each acquired physical quantity is sequentially written in a predetermined address area of the sampling data storage device 33 at intervals of 1 second. Here, the predetermined address area is an “address” registered as sampling data information in the acquired physical quantity registration information 51 shown in FIG.
Thus, since the sampling data storage device 33 is a storage device that temporarily holds the acquired physical quantity, a memory having a relatively small storage capacity and a high access speed is suitable. For example, a storage device such as a cache memory Is used.

The storage device 34 has an acquired physical quantity storage unit 341 that stores each acquired physical quantity output from the control device 31 at a predetermined output interval in a predetermined address area, and each calculation output from the control device 31 at a predetermined output interval. An arithmetic physical quantity storage unit 342 that stores physical quantities in a predetermined address area, a primary data storage unit 343 that holds an acquired physical quantity corresponding to a predetermined event, and the like.

The acquired physical quantity processing unit 311 executes predetermined calculation processing based on each acquired physical quantity registration information 51 (see FIG. 3) distributed and stored in each table of the storage device 32.
Similarly, the calculated physical quantity processing unit 312 performs a predetermined calculation process based on the calculated physical quantity registration information 52 (see FIG. 4) distributed and stored in each table of the storage device 32.
Based on the output interval information stored in the store table 326, the output processing unit 313 stores the acquired physical quantity and the calculated physical quantity received from the acquired physical quantity processing unit 311 and the calculated physical quantity processing unit 312 in the acquired physical quantity storage unit in the storage device 34. 341 or the calculated physical quantity storage unit 342, and outputs to the SOAP interface 315.
When the registration information change unit 314 receives the registration change instruction information from the logger server device 6 or the WEB server device 7 connected via the Internet 100, the registration information change unit 314 stores the information in the storage device 32 based on the registration change instruction information. A process for collectively changing various existing registration information described in a distributed manner in each table and a process for adding or deleting new registration information in a batch are performed.

The SOAP interface 315 converts the acquired physical quantity or the calculated physical quantity received from the output processing unit 313 into a SOAP (Simple Object Access Protocol) message in a predetermined format, and outputs the SOAP message to the communication unit 35.
Specifically, when an acquired physical quantity is received, the acquired physical quantity is described as a SOAP text, and attribute information of the acquired physical quantity (for example, basic information of the acquired physical quantity registration information 51 is used) is an envelope element. Is generated, and the SOAP message is output to the communication unit 35 to be transmitted to the logger server device 6 and the WEB server device 7 connected via the Internet.
Similarly, when an arithmetic physical quantity is received, the arithmetic physical quantity is described as a SOAP text, and attribute information of the arithmetic physical quantity (for example, basic information and calculation rule of the arithmetic physical quantity registration information 52) is described as an envelope element. A SOAP message is created, and the SOAP message is output to the communication unit 35 so as to be transmitted to the logger server device 6 and the WEB server device 7 connected via the Internet.
The communication unit 35 outputs the SOAP message received from the SOAP interface 315 to the Internet 100 in order to deliver it to a predetermined destination.

  In this way, various information is transmitted as a SOAP message, so it is possible to pass through security walls such as firewalls, and even between terminals with different platforms, information can be passed without any trouble. It becomes. As a result, it is possible to deliver information to the transmission destination safely and efficiently.

First, processing for an operation state monitoring request, which is a basic operation of the operation state monitoring system of the present invention, will be described below.
(A) Regarding Operation State Monitoring Request Transmission Processing In the operation state monitoring system according to this embodiment shown in FIG. 5, the input device 82 of the terminal device 8 is operated by the customer, and the control device 84 is transmitted via the input device 82. Upon receiving information requesting monitoring of the operating state of the heat source system that is the monitoring target, the control device 84 creates an operating state monitoring request and transmits it to the WEB server device 7.
In the WEB server device 7 that has received the operation state monitoring request, the SOAP interface 723 edits the operation state monitoring request into a SOAP message of a predetermined format and transmits it to the logger server 6. The logger server 6 that has received this operation state monitoring request mainly performs various processes based on information stored in the secondary data storage unit 632. However, as described above, the various secondary data stored in the logger server 6 is supplementarily managed based on the primary data created by the logger 3 based on the SOAP message transmitted from the WEB server device 7. In the logger 3 that has received the SOAP message, the SOAP interface 315 analyzes the SOAP message, whereby various processes based on the operation state monitoring request from the terminal device 8 are performed by the processing units 313 to 315 of the control device 31. Realized.
Hereinafter, the processing contents executed by the processing units 313 to 315 of the control device 31 will be specifically described with reference to FIGS. 6 to 9.

(B) Operation Information Transmission Processing and Store Processing by Logger 3 First, as shown in FIG. 6, basic sensor processing is executed by the acquired physical quantity processing unit 311.
The acquired physical quantity processing unit 311 refers to a predetermined address set in advance in the device table 321 (step SA1), and executes the process described therein. For example, as this predetermined address, as shown in FIG. 3, an address in which sampling information of registration information A, which is the first registration information of the heat source system, is described is set.
The acquired physical quantity processing unit 311 refers to the reference destination address of the device table 321 and executes the process described here. For example, in this reference destination address, the address of the sampling data storage device 33 (see FIG. 2) that holds the acquired physical quantity related to the registration information A, the data error information of the acquired physical quantity, and the next process are described. The reference address of the basic sensor table 322 is described.

  In accordance with this description, the acquired physical quantity processing unit 311 reads the latest acquired physical quantity from the sampling data storage device 33 (see FIG. 2) (step SA2 in FIG. 6), and executes error determination on this acquired physical quantity (step SA3). Here, in the error determination, it is determined whether or not the data format itself of the acquired physical quantity is an error. For example, if the read data has a data length other than 8 bits, it is determined as an error.

As a result, if it is determined that there is a data error (“YES” in step SA3), the acquired physical quantity processing unit 311 describes an error event at a predetermined address in the event table 325 shown in FIG. 2 (step SA4). . If the number of data bits is an error, the failure is mainly due to a failure of the sensor itself or a disconnection of a signal line or the like.
As described above, when an error event is described at a predetermined address in the error event table 325, the output processing unit 313 detects the error event and outputs information related to the error to the SOAP interface 315. As a result, a message notifying an error in a predetermined format is created and transmitted to the WEB server device 7 or the like via the communication unit 15.

On the other hand, if it is not the data error (“NO” in step SA3 in FIG. 6), the next reference destination address described in the device table 321 is referred to (step SA5) and described here. Execute the process.
For example, the basic table 322 describes the reference information of the link table 324 in which offset information, the sampling interval, and the next processing are described, along with the basic information of the acquired physical quantity (see FIG. 3).

In accordance with this description, the acquired physical quantity processing unit 311 applies an offset or the like to the acquired physical quantity related to the registration information A, and then refers to the reference destination address of the link table 324 (step SA6).
In the reference destination address of the link table 324, when the calculated physical quantity is calculated using the acquired physical quantity, the reference destination address of the extended sensor table for calculating the calculated physical quantity is described.
On the other hand, in the case where the physical quantity is not used for calculation of the calculated physical quantity, such as the acquired physical quantity related to the registration information A (see FIG. 3), event processing is performed on the reference destination address of the link table 324. Reference address of the event table is described.
Therefore, in the case of the process, the reference address of the event table is described (“YES” in step SA7), and the event process is executed according to this description (step SA9).

In the event processing, as shown in FIG. 7, the reference destination address of the event table 325 is referred to (step SB1). The reference address of the event table 325 describes the error determination information (see FIG. 3) of the acquired physical quantity and the reference address of the store table 326 in which the next processing is described.
The acquired physical quantity processing unit 311 performs an error determination according to this description (step SB2), and if it is a normal value (“YES” in step SB3), by referring to the reference destination address of the store table 326, store processing is performed. Is executed (step SB5).
On the other hand, if the acquired physical quantity is not a normal value as a result of the error determination (“NO” in step SB3), for example, an error event is described at a predetermined address in the event table 325 (see FIG. 2).

In the store process, as shown in FIG. 8, the reference destination address of the store table 326 is referred to (step SC1). In the reference destination address of the store table 326, the output destination (that is, “1 minute”) of the acquired physical quantity and the reference destination address of the device table 321 relating to the acquired physical quantity relating to the registration information B that is the next acquired physical quantity are described. .
Whether the output processing unit 313 matches the output interval, that is, whether one minute has elapsed since the last time the acquired physical quantity related to the registration information A was stored in the acquired physical quantity storage unit 341 of the storage device 34 (see FIG. 2). to decide. As a result, since the process is performed in increments of one second, since one minute has not yet elapsed since the previous storage, “NO” is obtained, and the current acquired physical quantity is held in a predetermined storage area in the control device 31. Then, the process proceeds to the basic sensor process shown in FIG. 5 (step SC5).

As a result, the basic sensor process relating to the next acquired physical quantity, that is, the registration information B is executed according to a predetermined procedure described in the reference destination of each table, as described above.
Here, the acquired physical quantity related to the registration information B is also used to calculate the calculated physical quantity related to the registration information D, as shown in FIG. Accordingly, the link table 324 referred to in step SA6 of the basic sensor process shown in FIG. 6 describes the reference address of the extended sensor table. Therefore, in the basic sensor process for the acquired physical quantity related to the registration information B, “NO” is determined in step SA7, and the process proceeds to the extended sensor process SA8.

In the extended sensor processing, as illustrated in FIG. 9, the reference physical address of the extended sensor table 323 is referred to by the arithmetic physical quantity processing unit 312 (step SD1).
The reference address of the extended sensor table 323 describes the basic information and calculation rule of the calculated physical quantity calculated using the acquired physical quantity related to the registration information B, and the reference destination address describing the next process. ing.
Next, the calculated physical quantity processing unit 312 determines whether or not all the acquired physical quantities necessary for the calculation are satisfied (step SD2). As a result, since the acquired physical quantity related to the registration information C is necessary for the calculation, it is determined that the acquired physical quantity is not satisfied (“NO” in step SD2), and the current acquired physical quantity is held in a predetermined storage area in the control device 31. (Step SD3), the extended sensor process is once ended, and the process returns to the basic sensor process related to the registration information B (Step SD4).

  In the basic sensor process, as shown in FIG. 6, event processing (see SA9 in FIG. 6 and FIG. 7) is executed for the acquired physical quantity related to the registration information B in the same manner as the acquired physical quantity related to the registration information A described above. Further, the store process (see FIG. 8) is executed, and the basic sensor process of the acquired physical quantity related to the next registration information C is executed.

  The acquired physical quantity related to the registration information C is used to calculate the calculated physical quantity related to the registration information D, similarly to the acquired physical quantity related to the registration information B described above. Therefore, in step SA7 of the basic sensor process shown in FIG. 6, the process proceeds to the extended sensor process SA8, and the same reference destination as the acquired physical quantity related to the registration information B is referred to.

Here, in this case, in step SD2 in FIG. 9, in order to satisfy all the acquired physical quantities required for the calculation, the process proceeds to step SD5, and the calculation is performed according to the calculation rule using the acquired physical quantities related to the registration information C and D To calculate the calculated physical quantity. When the calculated physical quantity is calculated in this way, event processing SD6 is performed on the calculated physical quantity.
In the event process (see FIG. 7), similarly to the above-described acquired physical quantity, an error determination is performed on the calculated physical quantity. Executed.
In the store process, the output processing unit 313 refers to the reference address of the store table in which the output interval information of the calculated physical quantity is described (step SC1), and determines whether or not the output interval matches (step SC1). SC2). As a result, as with the acquired physical quantity related to the registration information A and the like described above, “NO” is determined because one minute has not yet passed since the previous storage, and the current calculated physical quantity is stored in a predetermined storage area in the control device 31. The subsequent basic sensor processing is executed by holding and referring to the reference destination address described in the store table (step SC5).

  In the basic sensor process, the process of the acquired physical quantity related to the registration information C is interrupted by the extended sensor process (step SA8), and therefore event processing that is subsequent processing of the extended sensor process is executed (step SA9). Then, event processing (see FIG. 7) and store processing (see FIG. 8) for the acquired physical quantity of the registration information C are executed according to a predetermined procedure.

  Then, the processes according to FIGS. 6 to 9 described above become a series of loop processes, and the acquired physical quantity and the calculated physical quantity related to all the registration information (see FIGS. 3 and 4) related to the heat source system to be monitored are targeted. It is repeatedly executed, and the acquired physical quantity and each calculated physical quantity are stored in a predetermined storage area in the storage device 34 based on the output interval information of each registration information (see step SC3 in FIG. 8) and output to the SOAP interface 315. The Rukoto.

  In this embodiment, since the sampling interval of the basic sensor 2 is set to 1 second, the acquired physical quantity registration information 51 (see FIG. 3) and the calculated physical quantity registration information 52 registered for the heat source system to be monitored. The processing shown in FIGS. 6 to 9 (see FIG. 4) is also executed at intervals of 1 second, and the processing is completed in less than 1 second. Therefore, for example, when the output interval is set to “1 minute”, the acquired physical quantity is stored in the storage device 34 for the first time when the above processing for the acquired physical quantity related to the registered information is executed 60 times. And output to the SOAP interface 315 (see step SC3 in FIG. 8). Further, the 59 acquired physical quantities held in the predetermined storage area in the control device until then are deleted (see step SC4 in FIG. 8).

Next, by performing the processing described above, the acquired physical quantity and the calculated physical quantity are output from the output processing unit 313 to the SOAP interface 315 illustrated in FIG. 2 at each output interval.
The SOAP interface 315 performs the following processing every time the acquired physical quantity or the calculated physical quantity is received from the output processing unit 313.
First, basic information such as an acquired physical quantity input from the output processing unit 313 is acquired from the basic sensor table 322 or the extended sensor table 323. Then, a SOAP message in which the acquired physical quantity or the calculated physical quantity is described as a SOAP text, and the corresponding basic information is described as an envelope is created, and this SOAP message is stored in the logger server device 6 (see FIG. 5) shown in FIG. It transmits to the WEB server apparatus 7. Thereby, the SOAP message is transmitted to the device via the Internet 100.

(C) Operation Information Providing Process to Terminal Device 8 in WEB Server Device When the WEB server device 7 shown in FIG. 5 receives a SOAP message, the SOAP interface 723 analyzes the SOAP message and displays the contents as a screen data creation unit. To 721. The screen data creation unit 721 creates the latest monitoring screen data by reflecting the input content, that is, the acquired physical quantity or the calculated physical quantity in a predetermined monitoring screen data format, and sends this monitoring screen data to the terminal device 8. To send.
The terminal device 8 that has received the monitoring screen data analyzes the monitoring screen data and displays it on the output device 83. As a result, the monitoring screen of the heat source system, for example, a schematic representation of the heat source system to be monitored, the location where the acquired physical quantity and the calculated physical quantity are detected (for example, the mounting position of the basic sensor), and their values A screen and the like shown in association with each other are displayed.

(D) Store Processing in Logger Server Device 6 When the logger server device 6 shown in FIG. 5 receives a SOAP message, as in the case of the WEB server device 7 described above, the SOAP message is analyzed by the SOAP interface 622. The attribute of the acquired physical quantity or the calculated physical quantity included in the SOAP message is determined based on the basic state described in the envelope.
The acquired physical quantity and the like are written in a predetermined storage area in the primary data storage unit 631 specified according to the attribute.
The acquired physical quantity or the like written in the primary data storage unit 631 is subjected to a complementing process by the complementing processing unit 621, and then stored in a predetermined storage area of the secondary data storing unit 632 specified according to the attribute information. Stored.
Thus, the acquired physical quantity and the calculated physical quantity transmitted from the logger 3 are accumulated in the logger server device 6.

[2-2. (Data transmission processing for instantaneous value request)
Next, to the WEB server device 7, the logger server device 6, and the logger 3 when an instantaneous value monitoring request (here, an instantaneous value monitoring request for the acquired physical quantity related to the registration information A) is transmitted from the terminal device 8. The processing performed will be described with reference to FIG. In FIG. 5, a part of the configuration of the logger 3 is omitted.
In this case, the instantaneous value monitoring request transmitted from the terminal device 8 is transmitted to the WEB server device 7. In the WEB server device 7 that has received the instantaneous value monitoring request, the SOAP interface 723 edits the instantaneous value monitoring request into a SOAP message of a predetermined format and transmits it to the logger 3.

When the logger 3 receives the instantaneous value monitoring request as a SOAP message, the logger 3 executes a process of transmitting the latest acquired physical quantity (instantaneous value) related to the registration information A to the WEB server device 7 as an interrupt process. Send instantaneous value over 1 minute.
When the WEB server device 7 receives the SOAP message related to the instantaneous value, the screen data creation unit 721 creates monitoring screen data reflecting the instantaneous value, and transmits it to the terminal device 8. Thereby, the instantaneous value of the acquired physical quantity related to the registration information A is displayed on the output device 83 of the terminal device 8.
Further, the acquired physical quantity related to the registration information A is transmitted from the logger 3 to the WEB server device 7 at intervals of 1 second over 1 minute. The WEB server device 7 holds this value in a predetermined storage area in the control device 72 without providing it to the terminal device 8 except for the initial instantaneous value.
As described above, when an instantaneous value monitoring request is received from the terminal device 8, an instantaneous value for one minute is ensured, and the instantaneous value monitoring request made within one minute is prepared. Thereby, it becomes possible to respond promptly to a request again.
Further, for such an instantaneous value monitoring request, since communication traffic and arithmetic processing increase compared to the normal value, the WEB server device 7 considers the state of such communication traffic and the like and is within a possible range. Thus, the instantaneous value monitoring request may be transmitted to the logger 3.

[2-3. About data transmission by complementary processing)
Next, a store data complementing process performed when a part of the data stored in the storage device 63 of the logger server device 6 is lost will be described.
For example, when the store data three days ago has disappeared, the complement processing unit 621 creates retransmission instruction information for the disappeared store data and outputs this to the SOAP interface 622. The SOAP interface 622 edits the retransmission instruction information into a SOAP message of a predetermined format and transmits it to the logger 3.

When the logger 3 receives the retransmission instruction information as a SOAP message, the logger 3 stores store data in a range instructed to be retransmitted, that is, store data three days ago, as well as an acquired physical quantity storage unit 341 (see FIG. 2) and a calculation The information is read from the physical quantity storage unit 342 (see FIG. 2), and the information is stored in the primary data storage unit 343.
Then, the data stored in the primary data storage unit 343 is transmitted little by little to the logger server device 6.
Here, as described in the above basic operation, the acquired physical quantity and the calculated physical quantity are periodically transmitted as SOAP messages according to the output interval information from the logger 3 to the logger server device 6. In the transmitted SOAP message, there is an empty space where data can be written. Therefore, by writing the store data of 3 days before the request for retransmission together with its attribute information little by little in the empty part of the normally transmitted SOAP message and transmitting it to the logger server device 6, the data can be efficiently stored. Re-transmission can be performed.

  Also at this time, the attribute information of the acquired physical quantity and the calculated physical quantity to be retransmitted is described in the envelope so that the logger server device 6 can quickly determine which part is the data due to the retransmission request. Can do.

The control device 31 can easily identify transmitted data and untransmitted data by setting a flag or the like for the transmitted data in the retransmitted data stored in the primary data storage unit 343. It becomes possible. Thereby, for example, even when the communication with the logger server device 6 is disconnected, it is possible to execute the retransmission process promptly.
In addition, when such a re-transmission request is made and the arithmetic processing in the logger 3 is hindered, error information is transmitted to the logger server device 6 as a transaction. As described above, the logger 3 executes the retransmission process within a range that does not affect the normal process.

[2-4. (Registration information batch change process)
Next, registration information batch change processing for collectively converting, adding, and deleting registration information distributed and stored in various tables in the storage device 32 of the logger 3 will be described.
For example, in the heat source system 10 shown in FIG. 1, when a new location to be monitored occurs and monitoring is started by newly installing the basic sensor 2, acquisition corresponding to the newly added basic sensor 2 is obtained. The physical quantity registration information 51 (see FIG. 3) needs to be registered in the logger 3. Further, when the existing basic sensor 2 is replaced or removed, it is necessary to change the acquired physical quantity registration information 51.
In such a case, the acquired physical quantity registration information and the like in the logger 3 can be added, changed, and deleted very easily by executing processing according to the following procedure.

First, when the control device 84 accepts a request to change registration information by operating the input device 82 of the terminal device 8 by the user, the control device 84 sends a request to change the registration information to the WEB server device 7. Send.
In the WEB server device 7 that has received the registration information change request, the screen data creation unit 721 in the control device 72 refers to the data format stored in the screen data storage unit 731, thereby registering information change screen data. The registration information change screen data is transmitted to the terminal device 8.

As a result, the terminal device 8 analyzes the screen data received from the WEB server device 7 and displays it on the output device 83. On this registration information change screen, an instruction to input information necessary for changing the registration information is displayed.
For example, when the basic sensor 2 is added, each piece of information (sampling data information, basic information, etc.) constituting the acquired physical quantity registration information 51 shown in FIG. 3 is displayed as an input item. When it is desired to increase items to be monitored by calculation, each piece of information (basic information, calculation rule, etc.) constituting the calculated physical quantity registration information 52 shown in FIG. 4 is displayed as an input item.
When the input to these input items is completed and a transmission operation is performed, the control device 84 accepts this and transmits the input information to the WEB server device 7.

In the WEB server device 7, registration change instruction information for collectively changing the registration information in the logger 3 is created based on the information received from the terminal device 8.
Specifically, the registration change instruction creation unit 722 registers the input information for each item received from the terminal device 8 in each item of the batch registration table stored in the batch registration table storage unit 732, thereby registering. Create change instruction information. This registration change instruction information includes, for example, new acquired physical quantity registration information and calculated physical quantity registration information in various tables in the storage device 32 provided in the logger 3 according to their attributes and associating them as one program. This is an execution program.
Then, the SOAP interface 723 creates a SOAP message by editing the registration change instruction information in a format of a predetermined format, and transmits this to the logger server device 6.

  When the logger server device 6 receives the SOAP message from the WEB server device 7, the SOAP interface 622 analyzes the SOAP message. As a result, if it is determined that this message is registration change instruction information, the body of this message is written in the SOAP message storage unit 633 in the storage device 63 and a SOAP message similar to the SOAP message received from the WEB server device 7 is written. Is transmitted to the logger 3.

When the logger 3 receives the SOAP message from the logger server device 6, the SOAP interface 315 analyzes the SOAP message. As a result, if it is determined that this message is registration change instruction information, the body of this message is output to the registration information change unit 314.
The registration information changing unit 314 additionally describes new acquired physical quantity registration information and the like in various tables in the storage device 32 by executing the execution program transmitted as the billion change instruction information. Thereby, the acquired physical quantity registration information of the basic sensor newly added this time is described in various tables in the storage device 32.
As a result, processing similar to that for other acquired physical quantities is also executed for the acquired physical quantities acquired by the newly installed basic sensor.

The same applies to the process of registering and updating the calculated physical quantity registration information, but it is possible to add the following process by taking advantage of the characteristic that the calculated physical quantity is acquired by calculation.
For example, when the calculated physical quantity registration information is newly added, the calculated physical quantity is retroactively calculated by using the acquired physical quantity acquired in the past according to the calculation rule described in the registration information. Is calculated.
Specifically, the acquired physical quantity stored in the acquired physical quantity storage unit 341 of each storage device 34 is associated with time information when the acquired physical quantity is detected. Therefore, for example, when the acquired physical quantity x and the acquired physical quantity y are detected by the respective basic sensors, “acquired physical quantity x / acquired physical quantity y (the acquired physical quantity x divided by the acquired physical quantity y)” is calculated as a calculation rule. When newly registered as physical quantity registration information, the control device 31 extracts the acquired physical quantity x and the acquired physical quantity y detected at the same time from the acquired physical quantity storage unit 341 of the storage device 34, and extracts the acquired acquired physical quantity x. The value divided by the acquired physical quantity y is stored in a predetermined storage area of the calculated physical quantity storage unit 342 of the storage device 34 as a new calculated physical quantity.
This makes it possible to obtain the calculated physical quantity even in the past. Even in this case, if there is no corresponding acquired physical quantity, it is impossible to calculate the calculated physical quantity retroactively.

In the batch change process described above, the case where the user performs input for all input items has been described. However, instead of this, the input process can be performed as follows.
For example, the acquisition physical quantity registration information of the basic sensor currently popularized is registered in advance in the batch registration table storage unit 732 of the storage device 732 of the WEB server device 7. At this time, product identification information (for example, a serial number) of each basic sensor is described as identification information of each acquired physical quantity registration information.
When a registration information change request is received from the terminal device 8, screen data for inputting a serial number or the like of a newly installed basic sensor is transmitted to the terminal device 8.
Thus, when the serial number of the newly installed basic sensor is input and this information is received by the WEB server device 7, the registration change instruction creating unit 722 in the WEB server device 7 uses the serial number as a search key. By searching the collective registration table storage unit 732 described above, acquisition physical quantity registration information of a newly installed basic sensor is automatically acquired. And based on this acquired information, the above-mentioned registration change instruction information is created.

  In this way, by registering acquired physical quantity registration information corresponding to various basic sensors in the batch registration table storage unit 732 in advance, the user does not need to input the acquired physical quantity registration information, and registration information accompanying the addition of the basic sensor. It is possible to greatly reduce the work load related to the input operation.

[2-5. Other operations of WEB server device]
Further, as described above, the WEB server device 7 not only transmits monitoring screen data at a predetermined output interval, but also creates monitoring screen data according to various requests from the terminal device 8 and is a monitoring target. Much information about the heat source system can be provided.

For example, from the terminal device 8 shown in FIG. 5, for the acquired physical quantity related to the registration information A, the monthly average in this year (for example, 2002) is compared with the monthly average in the previous year (for example, 2003). When the monitoring request information is received, the screen data creation unit 721 of the WEB server device 7 executes the following process.
First, the screen data creation unit 72 of the WEB server device 7 acquires all the acquired physical quantities corresponding to the period for which the monitoring request has been received from the logger server device 6 and holds it in a predetermined storage area in the control device 72.
Subsequently, the screen data creation unit 721 computes an average value of each acquired physical quantity for each held period for each month, and creates monitoring screen data for comparing and displaying the computed monthly averages. This can be realized, for example, by inputting the calculated average value of each month according to the data format of the monthly average comparison display screen stored in the screen data storage unit 731 in advance. Then, when monitoring screen data for comparing and displaying monthly averages is created based on the data format, the screen data creating unit 721 transmits the monitoring screen data to the terminal device 8. As a result, on the output device 83 of the terminal device 8, a comparison display screen of the acquired physical quantities related to the registration information A in the previous year and the current year is displayed.

As described above, the operating state monitoring system according to the present embodiment has the following effects.
As shown in FIG. 2, since the logger 3 includes a calculation physical quantity processing unit 312 that calculates a calculation physical quantity, not only the acquisition physical quantity detected by the basic sensor actually attached to the monitoring target, but also the calculation from these acquisition physical quantities. It is also possible to output the calculated physical quantity obtained by. Thereby, for example, by registering a calculation rule for the state quantity desired to be obtained as a monitoring item, it is possible to monitor a state quantity or the like that is normally difficult to monitor.
Also, the registration information change in which the logger 3 adds, changes, and deletes the acquired physical quantity registration information 51 (see FIG. 3) and the calculated physical quantity registration information (see FIG. 4) based on the registration change instruction information received from the outside. Since the unit 314 is provided, the acquired physical quantity registration information and the like can be easily added even from a remote location.
As a result, it is possible to greatly reduce the labor and time associated with the addition of the basic sensor 2 and the like, and it is possible to complete the setting operation in an extremely short time.

  Further, since the logger 3 includes the output processing unit 313 that stores the acquired physical quantity and the calculated physical quantity in a predetermined storage area of the storage device 34 based on the output interval information, the output interval information is determined according to the properties and characteristics of the acquired physical quantity and the like. By optimally setting and registering, it is possible to extract, select and store data necessary for operation monitoring of the heat source system 10 (see FIG. 1) to be monitored. As a result, the amount of data to be stored can be reduced, and an efficient data store can be realized.

Further, since the logger 3 includes a SOAP interface 315 that associates the acquired physical quantity and the calculated physical quantity with their attribute information and transmits the SOAP message as a SOAP message, the apparatus that has received the SOAP message is included in the SOAP message. There is an effect that it is possible to easily determine what information is the acquired physical quantity and the calculated physical quantity.
Furthermore, the logger 3 describes the attribute information in the envelope element of the SOAP message, so that even if the information reaches the final destination via a plurality of devices, it is interposed in the communication path. In each apparatus, the information is appropriately handled, and in the apparatus that is the final transmission destination, the information can be appropriately acquired and managed.
Furthermore, the logger 3 executes the process according to the acquired physical quantity registration information described in a distributed manner in each of the tables 321 to 326, thereby actually executing a program in which a series of processing contents are written. The processing procedure can be changed very easily while obtaining the same effect as the above.

  Also, as shown in FIG. 5, the logger server device 6 includes the complement processing unit 621, and therefore, when the acquired physical quantity received from the logger 3 is deficient, the secondary is obtained by complementing. Information stored in the data storage unit 632 can be made more complete.

As shown in FIG. 5, the screen data creation unit 721 of the WEB server device 7 receives the acquired physical quantity and the calculated physical quantity received from the logger 3 based on the monitoring request information received from the terminal device 8 or 9, and a predetermined amount. Since the monitoring screen data is created from the image configuration data and transmitted to the terminal device 8 or 9, the operating state of the heat source system 10 to be monitored can be provided as screen information in an easy-to-understand manner.
In addition, since the WEB server device 7 includes a registration change instruction creation unit 722 that creates registration change instruction information for collectively registering acquired physical quantity registration information and calculated physical quantity registration information stored in the logger 3, monitoring is performed. It is possible to very easily realize the change of registration information performed in accordance with the addition, change, and deletion of items.

Further, although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and includes design changes and the like without departing from the gist of the present invention.
For example, in the present embodiment described above, the data stored in the storage device 34 of the logger 3 and the secondary data storage unit 632 of the logger server device 6 are simply different depending on whether or not the complementary processing is performed. Although the same data is stored, instead of this, the functions and roles of the logger 3 and the logger server device 6 may be divided into two, and data suitable for each may be stored. Specifically, the storage device 34 of the logger 3 stores the acquired physical quantity and the calculated physical quantity in the past year, while the secondary data storage unit 632 of the logger server apparatus 6 stores, for example, the logger 3 Data obtained by thinning out data stored in the storage device 34 may be stored over the past several years.
