Description

  The present invention relates to a setting device, a setting system, a program, a program recording medium, and a setting method.

  Field devices that perform calculation processing based on parameter values are set to calculate their output values before use. Here, field devices include sensor devices such as flow meters and temperature sensors, valve devices such as flow control valves and on-off valves, actuator devices such as fans and motors, cameras and videos that capture the situation and objects in the plant. Such devices as imaging devices, acoustic devices such as microphones and speakers that collect abnormal sounds in the plant and emit alarm sounds, position detection devices that output position information of each device, and the like. As an example of the prior art, a multi-variable transmitter, which is a differential pressure type flow meter, calculates and outputs a flow rate based on a differential pressure, static pressure, temperature detected by a sensor, and a preset flow rate calculation parameter. . In order to set the flow rate calculation parameter, for example, a tool operating on a personal computer (PC) calculates the flow rate calculation parameter based on the input from the user.

  For example, FIG. 4 of Non-Patent Document 1 discloses a functional block diagram of a mass flow measurement system. In this functional block diagram, the tool (EJXMVTool) outputs the parameter values in order to set the calculation flow parameters of the differential pressure type flow meter (EJX910).

  The information on the flow rate application that is the target of the flow rate setting is usually static setting information, and once set, it is not necessary to change the set value during plant operation. In other words, using the devices and functions described in Non-Patent Document 1, only setting work is performed on a field device (such as a multivariable transmitter) before operation using a flow rate setting tool that operates on a stand-alone PC in advance. It was good.

Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a schematic device configuration of a setting system for setting field devices. In the figure, reference numeral 10 denotes a setting system. The setting system 10 includes a client computer 1, a client device 2, an analyzer 3, a server computer 5 (setting device), and a multivariable transmitter 8 (field device). The client computer 1, the client device 2, the analyzer 3, and the server computer 5 are connected by a network 100 and can communicate with each other. The network 100 performs communication using, for example, IP (Internet Protocol). Further, there is a communication means for sending data for setting the multivariable transmitter 8 from the server computer 5 to the multivariable transmitter 8.

  In the present embodiment, the event described below is data received by the server computer 5 and can be a trigger for the server computer 5 to set the multivariable transmitter 8. The client computer 1, the client device 2, and the analyzer 3 transmit an event to the server computer 5 when a predetermined event occurs. The client device 2 or the analyzer 3 transmits an event when a predetermined time arrives (based on a timer setting or the like in each device) or when a measured value or a calculated value changes (for example, at a reference time) When there is a change greater than a predetermined threshold value than the value). The client computer 1 transmits an event when there is an operation by a user or the like. When the server computer 5 receives the event and satisfies a predetermined condition, the server computer 5 starts processing for setting the multivariable transmitter 8. There are two types of events: static setting value calculation events and dynamic setting value calculation events. The static setting value calculation event can be a trigger for calculating the static setting value. The dynamic setting value calculation event can be a trigger for calculating the dynamic setting value. In the configuration shown in FIG. 1, it is the client computer 1 that sends out the static setting value calculation event. The client computer 1, the client device 2, and the analyzer 3 send the dynamic setting value calculation event.

The client computer 1 has a function of receiving an input regarding the static setting value or the dynamic setting value of the multivariable transmitter 8 and transmitting an event including the input value to the server computer 5. In the configuration of this embodiment, the main role of the client computer 1 is to transmit data for setting static setting values to the server computer 5. However, the client computer 1 may transmit data for setting the dynamic setting value to the server computer 5 at a relatively low frequency. Note that the client computer 1 performs communication with the server computer 5 via the network 100.
The client device 2 includes various sensors, has a function of measuring or calculating a physical quantity, and outputting measurement result data or calculation result data to the outside. Specifically, the client device 2 transmits measurement result data or calculation result data to the server computer 5 via the network 100. The client device 2 may be regarded as transmitting an event including measurement result data or calculation result data to the server computer 5.
The analyzer 3 identifies components contained in gas (natural gas or the like) using a sensor or the like, and analyzes the molar component ratio (component ratio) of each component. The analyzer 3 outputs the data of the type of component and the numerical value of the molar component ratio to the outside. Specifically, the analyzer 3 transmits data such as molar component ratio to the server computer 5 via the network 100. The analyzer 3 may be regarded as transmitting an event including the molar component ratio data to the server computer 5.
Note that the analyzer 3 includes a sensor and outputs physical quantity data (molar component ratio) to the outside. Therefore, the analyzer 3 can be regarded as one special example of the client device 2.

The server computer 5 has a function of causing the multivariable transmitter 8 to perform setting processing using data of the static setting value and the dynamic setting value of the multivariable transmitter 8. Regarding the static setting value, the server computer 5 uses data received from the client computer 1. Regarding the dynamic setting value, the server computer 5 uses data received from the client device 2 or the analyzer 3 or calculates based on the received data.
As an example, the server computer 5 waits for an event from the client device 2 or the analyzer 3, and sets the dynamic setting value of the multivariable transmitter 8 when the event is received. As another example, the server computer 5 sets a timer held by the server computer 5 in advance, and when the event that a predetermined time has arrived is detected by the timer, an inquiry (data transmission) to the client device 2 or the analyzer 3 is performed. Request). Then, the server computer 5 sets the dynamic setting value of the multivariable transmitter 8 based on the data (output value data) transmitted from the client device 2 or the analyzer 3 as a response to the inquiry.
For example, the server computer 5 receives data on the molar component ratio of gas from the analyzer 3. Then, the server computer 5 transmits the molar component ratio data to the multivariable transmitter 8 as dynamic setting value data.
The server computer 5 directly transmits a setting value to the multivariable transmitter 8 to cause the multivariable transmitter 8 to perform setting. Therefore, the server computer 5 may be referred to as a “setting device”.

The multivariable transmitter 8 is a kind of field device. The multivariable transmitter 8 is a device equipped with functions of a differential pressure gauge, a pressure gauge, a thermometer, and a flow rate calculator. Thereby, the multivariable transmitter 8 measures the differential pressure, static pressure, and temperature of the fluid. The multivariable transmitter 8 calculates the mass flow rate of the fluid based on the measured differential pressure, static pressure, and temperature. Then, the multivariable transmitter 8 outputs data of measurement values (or calculation result values) such as differential pressure, static pressure, temperature, and mass flow rate to the outside. The multivariable transmitter 8 includes a memory for storing flow rate calculation parameters therein. The multivariable transmitter 8 has a function of receiving set value data from the outside and writing the received set value into the memory as a flow rate calculation parameter. The flow rate calculator calculates the mass flow rate of the fluid based on each measurement value described above and referring to the set value (flow rate calculation parameter) read from the memory.
Note that the multivariable transmitter 8 itself having a function of calculating the mass flow rate of the fluid and transmitting values such as the obtained mass flow rate, temperature, and pressure (static pressure, differential pressure, etc.) is a related art. Can be realized.

  Note that a field device such as a multivariable transmitter includes a receiving unit, a storage unit, and an arithmetic unit. The calculation unit performs calculation processing using the dynamic setting value read from the storage unit as a parameter. The receiving unit receives a dynamic setting value transmitted from the server computer 5. The storage unit stores the dynamic setting value received by the receiving unit. That is, when the receiving unit receives the dynamic setting value, the field device writes the received latest dynamic setting value in the storage unit in the form of overwriting and updating the dynamic setting value originally stored in the storage unit.

  In the present embodiment, the static setting value is a setting value that is substantially unchanged for the multivariable transmitter 8. Alternatively, even if the static setting value can be changed, it is a setting value that remains unchanged at least for a predetermined period (for example, several weeks to several years (or more)). As a specific example, the data on the size of piping in the plant necessary for calculating the flow rate in the flow meter does not change unless the piping is replaced. The dynamic setting value is a setting value that can change relatively frequently in the multivariable transmitter 8. The dynamic setting value may vary depending on the environment / situation. For example, the set value based on the humidity to be measured is a dynamic set value. Further, for example, the set value based on the component ratio of the fluid to be measured (such as the molar component ratio of natural gas) is a dynamic set value in some cases. The dynamic setting value is recalculated and reset according to the environment / situation at that time within a predetermined period within a range (for example, not limited to this range) of several seconds to several hours or several days. .

  In addition, the function (each function part) which comprises each apparatus shown in FIG. 1 is implement | achieved using an electronic circuit, for example. Each functional unit may include a storage unit such as a semiconductor memory or a magnetic hard disk device as necessary. Each function may be realized by a computer and software.

In the configuration shown in FIG. 1, a plurality of client computers 1, client devices 2, and analyzers 3 may exist. The client computer 1 may not be included. In the case where the client computer 1 is not included, for example, the setting is already performed by the static setting value. In that case, only the setting by the dynamic setting value based on the event from the client device 2 or the analyzer 3 is performed. Further, after setting the static setting value using the client computer 1, the connection of the client computer 1 to the network 100 may be disconnected.
Alternatively, a system in which only one of the client device 2 and the analyzer 3 exists may be used.

When the client flow setting tool 11 is realized by a program, each function therein corresponds to a program module. The client flow setting tool 11 may constitute a DTM (Device Type Manager).

Further, as shown in the figure, the client flow rate setting tool 11 includes functions of an input unit 111 and a network output unit 112.

The network output unit 32 outputs the molar component ratio data for each component obtained by the molar component ratio analysis unit 31 to the outside. Specifically, the network output unit 32 transmits the output value to the outside via the network 100.

FIG. 5 is a functional block diagram showing a schematic configuration of functions provided in the server computer 5. As shown in the figure, the server computer 5 has a function of a server flow setting tool 51 inside. The server flow rate setting tool 51 can be realized, for example, by causing a CPU in the server computer 5 to execute a predetermined program. When the server flow rate setting tool 51 is realized by a program, each function therein corresponds to a program module. The server flow rate setting tool 51 is a tool having a function for setting the flow rate of the multivariable transmitter 8. The server flow setting tool 51 may be configured by a DTM (Device Type Manager).
Further, as shown in the figure, the server flow setting tool 51 includes a flow setting processing unit 52. The flow rate setting processing unit 52 performs flow rate setting (static flow rate setting and dynamic flow rate setting). The flow rate setting processing unit 52 includes an event receiving unit 521, a static setting processing unit 53, a dynamic setting processing unit 54, and a set value transmission unit 55.

The event receiving unit 521 receives an event from an external device. Here, the external devices are the client computer 1, the client device 2, the analyzer 3, and the like. As described above, there are two types of events, static setting value calculation events and dynamic setting value calculation events. When receiving the event, the event receiving unit 521 distributes the event to the static setting processing unit 53 or the dynamic setting processing unit 54 according to the type of the event. Specifically, when the event reception unit 521 receives a static setting value calculation event, the event reception unit 521 passes the static setting value calculation event to the static setting processing unit 53. In addition, when receiving the dynamic setting value calculation event, the event reception unit 521 passes the dynamic setting value calculation event to the dynamic setting processing unit 54.
The event receiving unit 521 may make an inquiry to the client device 2 or the analyzer 3 before receiving an event from the client device 2 or the analyzer 3. In that case, in response to the inquiry from the event receiving unit 521, the client device 2 or the analyzer 3 returns an event to the event receiving unit 521.
That is, the event receiving unit 521 receives an event (dynamic setting value calculation event) including an output value from the client device based on a physical quantity measured by an external client device (client device 2 or analyzer 3). Further, the event receiving unit 521 receives an event (a static setting value calculation event or a similar setting value calculation event) including a value input in the client computer 1 or the like.

  The static setting processing unit 53 includes a static flow rate setting value calculation unit 531. The dynamic setting processing unit 54 includes a dynamic flow rate set value calculation unit 542 (dynamic set value calculation unit) and a natural gas compression coefficient calculation unit 543 (dynamic set value calculation unit). .

The dynamic flow rate set value calculation unit 542 and the natural gas compression coefficient calculation unit 543 calculate the dynamic set value based on the dynamic set value calculation event received by the event reception unit 521. The dynamic flow rate set value calculation unit 542 and the natural gas compression coefficient calculation unit 543 may be collectively referred to as “dynamic set value calculation unit”. That is, the dynamic flow rate set value calculation unit 542 and the natural gas compression coefficient calculation unit 543 dynamically set the field device based on the output value included in the dynamic set value calculation event received by the event reception unit 521. The dynamic setting value that is the setting value of is calculated.
The dynamic flow rate set value calculation unit 542 calculates a dynamic set value based on the dynamic set value calculation event sent from the client device 2.
The natural gas compression coefficient calculation unit 543 calculates a dynamic setting value based on the dynamic setting value calculation event sent from the analyzer 3. Specifically, the natural gas compression coefficient calculation unit 543 calculates the natural gas compression coefficient based on the molar component ratio data for each component of the fluid (natural gas) included in the event sent from the analyzer 3. . The natural gas compression coefficient is one of dynamic setting values for performing dynamic setting of the multivariable transmitter. The natural gas compression coefficient calculation unit 543 calculates a set value for performing arithmetic processing based on, for example, the following standard natural gas calculation standards. Examples of the standard include AGA8 and ISO 12213: 1997.
The natural gas compression coefficient calculation unit 543 calculates a dynamic set value based on an event, and thus can be regarded as one special example of the dynamic flow rate set value calculation unit 542.

The setting value transmission unit 55 transmits the static setting value output from the static setting processing unit 53 and the dynamic setting value output from the dynamic setting processing unit 54 to the multivariable transmitter 8 that is the setting target. To do. Thereby, the setting process of the multivariable transmitter 8 based on a static setting value or a dynamic setting value becomes possible.
Normally, static setting values are not set frequently. However, when the event receiving unit 521 receives a static setting value calculation event for calculating the static setting value and the static flow rate setting value calculating unit 531 calculates the static setting value, the setting value transmitting unit 55 The given static setting value is transmitted to the field device to be set.

  Note that at least some of the functions of the devices such as the client computer 1, the client device 2, the analyzer 3, the server computer 5, and the multivariable transmitter 8 in the above-described embodiment may be realized by a computer. . In that case, a program for realizing this function may be recorded on a computer-readable recording medium, and the program recorded on this recording medium may be read into a computer system and executed. Here, the “computer system” includes an OS and hardware such as peripheral devices. The “computer-readable recording medium” is a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, a DVD-ROM, a USB memory, or a storage device such as a hard disk built in a computer system. That means. Furthermore, a “computer-readable recording medium” dynamically holds a program for a short time, like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line.

[Modification 1]
In the above embodiment, the case where the field device is the multivariable transmitter 8 has been described.
As a modification, field devices include, for example, sensor devices such as flow meters and temperature sensors, valve devices such as flow control valves and on-off valves, actuator devices such as fans and motors, and cameras that capture the situation and objects in the plant. Imaging equipment such as video and video, acoustic equipment such as microphones and speakers that collect abnormal sounds in the plant and emit alarm sounds, position detection equipment that outputs position information of each equipment, and other equipment Also good.
More specifically, the field device may be a Coriolis flow meter, an electromagnetic flow meter, a vortex flow meter, a differential pressure flow meter, an ultrasonic flow meter, or the like for measuring a flow rate. Moreover, the pressure gauge for measuring a pressure, a differential pressure gauge, etc. may be sufficient. Moreover, the thermometer for measuring temperature may be sufficient.
Also in this modification, the server computer 5 receives an event including output value data from the client device 2 or the like. Then, the server computer 5 calculates a dynamic setting value and a static setting value based on the received output value. Then, the server computer 5 sets the field device by transmitting the calculated dynamic setting value or static setting value to the field device.

[Modification 2]
In the second modification, the client flow setting tool 11 and the server flow setting tool 51 are configured as DTMs conforming to the standards of FDT ver. 2 and later (“FDT” is an abbreviation of “Field Device Tool”). Further, the flow setting tool can be executed in an open execution environment (on the FDT frame application) regardless of the manufacturing company. This enables dynamic setting even on a host system provided by a company different from the company that manufactures and sells field devices.

[Effects and Effects of Embodiments and Modifications]
As described above, according to the embodiment and the modification described above, the server computer 5 receives an output value from a device such as the client device 2 or the analyzer 3 via the communication unit. Then, the server computer 5 calculates a dynamic setting value or a static setting value based on the received output value, and automatically sets the field device using the dynamic setting value or the static setting value. Do. Thereby, in the case of dynamic setting, it becomes possible to automatically change the setting of the field device without manual intervention when the environment / situation changes. Thereby, for example, the accuracy of numerical values calculated by the field device is improved.

  The process in which the server computer 5 receives the output value from the client device 2 or the analyzer 3 and dynamically sets the field device does not require human intervention. In this process, no user interface is required, so automatic setting changes can be made during plant operation.

In the case of the first embodiment, for example, it is possible to perform a flow rate calculation that reflects the flow rate setting of dynamic information and the change of the molar component in the natural gas compression coefficient calculation process for each event occurrence. Thereby, the accuracy of the calculated flow rate is improved. For example, since dynamic setting is possible in the first embodiment, it is possible to output a more accurate value in an application for obtaining a natural gas transaction flow rate (mass flow rate).
In the prior art, such calculation of the transaction flow rate can be performed only on a controller such as a PLC, RTU, or flow computer. However, by applying this embodiment or the modification, it is possible to perform such a calculation of the transaction flow rate with the field device. This increases the number of applications that field devices such as multivariable transmitters can handle.

  As mentioned above, although embodiment and modification of this invention were explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design etc. of the range which does not deviate from the summary of this invention are included. It is.

  The present invention can be used for, for example, a measuring instrument used in a plant or the like. However, the application of the present invention is not limited to those exemplified here.
