Abstract

PURPOSE:To prevent the setting mistakes at the time when plural types of transmitters are set with use of a single portable terminal equipment. CONSTITUTION:When a parameter is set to a transmitter 2 from a portable terminal equipment 1 and this set parameter is inputted through a set value input part 11, a device type code generating part 12 produce the device type codes. A reception part 21 receives these codes and compares its own device type code with the received device type code through a device type comparison part 22. If the coincidence is secured between both codes, these coincident codes are set at a set value setting part 23. If not, a setting mistake is decided and a misset signal. is outputted to the equipment 1. Then the misset signal is displayed at a misset display part 13 of the equipment 1.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] This invention is a transmitter that transmits industrial quantities such as temperature, pressure, and flow rate as electrical signals, and in particular, a transmitter that can set parameters by connecting a mobile terminal (communicator) to the output line. Regarding transmitters.

0002

[Prior Art] Conventionally, industrial transmitters that detect industrial quantities such as temperature, pressure, and flow rate, convert them into electrical signals, and transmit the signals include:
A key for inputting parameters, etc. and a portable terminal (communicator) with a display are connected to the electrical signal transmission (output) line, and communication is performed with the transmitter, and a pulse-like signal is sent to the transmission line. So-called intelligent transmitters, which communicate by superimposing signals and enable remote settings for each transmitter, have been put into practical use.

0003

[Problems to be Solved by the Invention] With the conventional intelligent transmitter described above, one mobile terminal device can support multiple types of transmitters, such as differential pressure, gauge pressure, absolute pressure, and liquid level. The system is configured such that individual settings are made for each corresponding transmitter, and after the settings are completed for one transmitter, the mobile terminal is connected to the transmission line of the next transmitter. transmitters and configure different settings for different types of transmitters.

[0004] In this type of transmitter, if the settings are continued without initialization even after changing the mobile terminal, the contents of the setting parameters may differ depending on the transmitter, so the settings may be unintended by the operator. There was a problem that changes could be made. This invention has been made in view of the above-mentioned problem, and when changing the settings of multiple transmitters using a mobile terminal, there is a risk of incorrect settings for different types of transmitters. The purpose is to provide a transmitter without

[0005]

[Means and operations for solving the problems] A transmitter of the present invention includes a receiving section (21) that receives a model code added to a parameter and inputted from a mobile terminal (1), and a model code comparison section (22) that compares its own model codes; a setting section (23) that sets input parameters when the comparison result codes match;
An erroneous setting signal output section (24) is provided which outputs an erroneous setting signal if the codes do not match as a result of the comparison.

[0006] In this transmitter, the model code to be set is inputted from the mobile terminal in addition to the parameter setting values. The receiving section receives this, and the model code comparison section compares the received model code with its own model code. As a result of the comparison, if it is your own model code, it will be interpreted as a setting for yourself and you will perform settings (including setting changes), but
If the own model code and the received model code do not match, it is assumed that the setting is not for the user, and an incorrect setting signal is transmitted to the mobile terminal.The mobile terminal displays this on the display to notify the operator. will find out about the incorrect settings.

[0007]

[Examples] The present invention will be explained in more detail with reference to Examples below. FIG. 2 is a schematic block diagram of a system showing one embodiment of the present invention. In the figure, transmitter 2-
A is a differential pressure transmitter with a maximum range of 40,000 mmH20, and is connected to the power supply 3-A and the load resistor 4 via the transmission line 5-A.
-A, and the transmitter 2-B is a gauge pressure transmitter with a maximum range of 20Kgf/cm2 or more, and is also connected to the power supply 3-B and load resistor 4-B via the transmission line 5-B. These transmitters 2-
Mobile terminal 1 is connected to transmission line 5-A and 2-B respectively.
Assume that the connection is switched to 5-B and the parameter settings are changed. First, transmitter 2-A has 4Kgf/
Naturally, the range settings are different when setting the maximum range conversion value to 100% with the data weight of cm2 and when setting the maximum range conversion value to 20% with the data weight of 4Kgf/cm2 of transmitter 2-B. Therefore, mobile terminal 1
When setting parameters for transmitters 2-A, 2-B, or other transmitters, these are added to the parameter settings as shown in FIG. It is designed to be sent with a model code of .

[0008] The mobile terminal 1 and the transmitter 2 are each equipped with means as shown in FIG. , and further includes a model code generation section 12. All of these will be input using keys. The mobile terminal 1 also includes an incorrect setting display section 13. On the other hand, the transmitter 2 has a receiving section 21 that receives setting values with a model code sent from the mobile terminal 1, and a model code that compares the sent model code with its own model code stored in advance. When the model codes compared by the comparing unit 22 and the model code comparing unit match, the code is sent to the setting unit 23, which sets the sent setting values, that is, parameters, or changes the settings to the previous setting values. If they don't match,
An erroneous setting signal output section 24 is provided to output an erroneous setting signal to the mobile terminal 1.

[0009] Now, for example, if a parameter of 4Kgf/cm2 is input to the transmitter 2-A using the ordinary mobile terminal 1,
Maximum range conversion value 100 for 40000mmH20
% range setting, and then connect mobile terminal 1 to transmitter 2.
-B and configure the settings, the data of 4Kgf/cm2 for transmitter 2-B will be the maximum range conversion value 2
Corresponding to 0%, erroneous settings with different weights will be made. Therefore, in this embodiment device, when inputting a parameter setting value from the mobile terminal 1, following the setting value, when setting it to the transmitter 2-A, the model code of the transmitter 2-A is input to the transmitter 2-A. -B, transmitter 2
- Send with the model code of B attached to each. In response to this, the transmitters 2-A and 2-B each make a model code determination.

For example, when the transmitter 2-A is connected to the transmission line 5-B of the transmitter 2-B of the mobile terminal 1, as shown in FIG. Receives the model code (step ST1), then determines whether the received code matches its own code (step ST2), and if the codes match, sets the setting value as its own parameter. However, if the received code does not match the own code, an incorrect setting signal is output to the mobile terminal 1, and the incorrect setting is corrected on the mobile terminal 1. Display (step ST
4). If this incorrect setting of the mobile terminal 1 is displayed, it means that the parameters have been set as they are without changing the model code, and the operator can notice the incorrect setting and change the original parameters corresponding to the transmitter 2-B. All you have to do is make the settings, and you can prevent incorrect settings.

[0011]

[Effects of the Invention] According to the present invention, when setting parameters for multiple models of transmitters using one mobile terminal, a model code is transmitted for each set value,
Since the transmitter side determines whether the code matches its own model code, incorrect settings can be reliably prevented.
