  The present invention relates to a support tool for a transmitter that measures and transmits a flow rate, and more particularly, a multivariable transmitter (multivariable mass flow transmitter) that inputs variables related to a plurality of physical quantities of a process and calculates these variables. Related to support tools.

  A multivariable transmitter will be described with reference to FIG. FIG. 3 is a block diagram showing an example of a general multivariable transmitter (see, for example, Patent Document 1).

  The multi-variable transmitter includes a differential pressure sensor 1, a pressure sensor 2, a temperature sensor 3, an analog / digital (A / D) converter 4, an analog / digital (A / D) converter 5, and an analog / digital (A / D) converter. 6, arithmetic processing means 7, memory 8, digital / analog (D / A) converter 9, output means 10, communication interface (I / F) 14 and others.

  The multivariable transmitter is connected to the external load 11 and the power supply 12 via a transmission line. Furthermore, the multivariable transmitter is connected to the support tool 13 via a transmission line.

  Further, the differential pressure sensor 1 detects a process differential pressure and converts it into an analog electric signal, and the A / D converter 4 converts the analog electric signal into a digital signal ed. The pressure sensor 2 detects the process pressure and converts it into an analog electrical signal, and the A / D converter 5 converts the analog electrical signal into a digital signal ep. Furthermore, the temperature sensor 3 detects the temperature of the process and converts it into an analog electrical signal, and the A / D converter 6 converts this analog electrical signal into a digital signal et.

  Second, in the support tool 13, the support tool automatically calculates transmitter parameters from user data. The transmitter parameters are formed of data that is difficult for humans to understand, including approximate coefficients used for multivariable transmitters. The transmitter parameter is a parameter for setting (flow rate) calculation in the multivariable transmitter to a predetermined value, for example.

  Third, transmitter parameters are downloaded from the support tool 13 to the transmitter via the transmission line and the communication interface 14. The downloaded transmitter parameters are stored in the memory 8.

  Fourth, if necessary, the transmitter parameters are uploaded from the multivariable transmitter to the support tool 13 via the multivariable transmission line and the communication interface 14.

  In this way, the support tool 13 performs flow rate setting of the multivariable transmitter.

  A multivariable transmitter that handles differential pressure, pressure, and temperature is a device in which such configuration is effective. In other words, if the configuration is not sufficient, the multivariable transmitter cannot function effectively.

  The multivariable transmitter has a plurality of flow rate setting modes. Specifically, one flow rate setting mode is an automatic compensation mode in which detailed setting is performed and precise flow rate calculation is performed, and the other flow rate setting mode is simple and simple. This is a basic mode for performing a simple flow rate calculation. Furthermore, the multivariable transmitter has a unique situation that there are many types of parameters to be set.

  Further, the support tool 13 switches between these modes and sets these detailed parameters by configuration, and operates the functions of the multivariable transmitter. Further, the flow setting input screen of the support tool 13 is formed from a plurality of pages.

In addition, the procedure execution state display unit (41, 42,..., 4n) highlights and displays only the portion of one procedure being executed, for example.

  Further, the flow rate setting mode holding buffer 23 is connected to the flow rate setting input screen 21. Furthermore, the flow rate setting mode holding buffer 23 stores a flow rate setting mode for computation in the transmitter selected via the flow rate setting input screen 21.

  Specifically, for example, when the flow rate setting mode is an automatic compensation mode, the flow rate setting mode holding buffer 23 stores a value 0. Furthermore, for example, when the flow rate setting mode is the basic mode (Basic Mode), the flow rate setting mode holding buffer 23 stores the value 1.

Further, for example, in the Basic Mode, there are procedures 1 to 3, and the flow rate setting procedure number holding buffer 24 stores one of the values 1 to 3 corresponding thereto.

  The procedure content explanation character string buffer 25 inputs the value of the flow rate setting mode holding buffer 23. Furthermore, the procedure content explanation character string buffer 25 stores in advance a specific description of the procedure content.

  Here, the configuration of the procedure content explanation character string buffer 25 will be described in detail with reference to FIGS. 1 and 2. FIG. 2 is a block diagram showing an embodiment of the procedure content explanation character string buffer 25 of the present invention.

  When the value of the flow rate setting mode holding buffer 23 in FIG. 1 is 0, the procedure content explanation character string buffer 25 in FIG. 2 selects the procedure content explanation character string buffer 50 for Auto Compensation Mode. When the value of the flow rate setting mode holding buffer 23 in FIG. 1 is 1, the procedure content description character string buffer 25 in FIG. 2 selects the Basic Mode procedure content description character string buffer 60.

  In FIG. 2, the procedure content explanation character string buffer 50 for Auto Compensation Mode is formed from a procedure 1 content explanation 51, a procedure 2 content explanation 52,..., A procedure n content explanation 5n. Similarly, the procedure content explanation character string buffer 60 for Basic Mode is formed of a procedure 1 contents explanation 61, a procedure 2 contents explanation 62,..., A procedure n contents explanation 6n.

  First, when the flow rate setting mode is Auto Compensation Mode, the procedure 1 content explanation display unit 31 in FIG. 1 is connected to the procedure 1 content explanation 51 in FIG. 2, and the procedure 2 content explanation display unit 32 in FIG. 2 is connected to the procedure 2 content explanation sentence 52,..., And the procedure n content explanation display section 3n in FIG. 1 is connected to the procedure n content explanation sentence 5n in FIG.

  As a result, the character string “select flow rate setting mode” is displayed on the procedure 1 content explanation display unit 31, and the character string “select primary element information” is displayed on the procedure 2 content explanation display unit 32. 3. The text string “select fluid type” is displayed on the 3 content explanation display portion 33, the text string “setting natural gas” is displayed on the procedure 4 content explanation display portion 34, and the procedure 5 content explanation display portion.

Displays the character string "Save and Download Data".

  In step 1, the flow rate setting procedure number holding buffer 24 stores the value 1, and only the procedure 1 execution state display unit 41 is lit. In step 2, the flow rate setting procedure number holding buffer 24 stores the value 2, and only the procedure 2 execution state display unit 42 is lit. Thereafter, the same operation is performed.

  That is, the flow rate setting order indicator 22 visually displays the setting order of the user data and indicates in real time which procedure is being worked on. Therefore, the operator can intuitively grasp what setting is performed in which order even for a large amount of user data extending over a plurality of pages. As a result, the operator can input user data efficiently.

  Next, when the flow rate setting mode is Basic Mode, the procedure 1 content explanation display unit 31 in FIG. 1 is connected to the procedure 1 content explanation 61 in FIG. 2, and the procedure 2 content explanation display unit 32 in FIG. 2 is connected to the procedure content description sentence 62 in FIG. 2, and the procedure content description display section 3n in FIG. 1 is connected to the procedure description content 6n in FIG.

  As a result, the character string “select flow rate setting mode” is displayed on the procedure 1 content explanation display portion 31, and the character string “basic mode parameter setting” is displayed on the procedure 2 content explanation display portion 32.
