Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventionally, a telemeter has been premised on the fact that there is no mistake in the wiring with the monitoring target device. Therefore, when the monitoring target device is reconfigured or in the event of accidental miswiring, it has been necessary to perform a rewiring reconfiguration operation again. This has required time-consuming and manpower-intensive countermeasures. When there is no wiring worker when miswiring is noticed after wiring, reordering etc. has been necessary.

[0005] Therefore, an object of the present invention is to provide a highly convenient telemeter that can be easily corrected even if miswiring or the like occurs.

Means for Solving the Problems

[0006] In a telemeter device that receives a signal related to the operating state of an external device at an input terminal and can display the operating state of the external device on a field display unit, the telemeter device is capable of correcting the assignment or association of the external device input to the input terminal and the information related to the operating state of the external device displayed on the field display unit.

Effects of the Invention

[0007] According to the present invention, it is possible to provide a highly convenient telemetry system that allows for easy correction of miswiring and other errors.

[0008] Further means and effects of the present invention will become apparent throughout the entire specification below. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification, the term CPU is used to mean an arithmetic unit. Therefore, the type and implementation form of any configuration having arithmetic functions are not limited. [Examples]

[0011] FIG. 1 is an explanatory diagram of a telemeter system. The telemeter device is composed of a telemeter main body 10 and a field display unit 30. The telemeter main body 10 has an input terminal 11, a CPU 12, and a memory 13. The memory can be of any type as long as it can function as a storage device. It can also be integrated with the CPU 12.

[0012] The input terminal 11 is directly or indirectly connected to an external device, and the operation information of the external device is input to the input terminal 11.

[0013] The CPU 12 assigns the information input to the input terminal and the information such as the name of the external device from the information in the memory 13.

[0014] The field display unit 30 has a display device 31 and a CPU 32. It is desirable to implement the field display unit 30 by applying an application program to a general-purpose PC or a tablet device. Also, when configured with a tablet device, portability can be achieved. It is more desirable because an operator can check and verify the information displayed on the display device 31 while looking at the actual external device at the site.

[0015] Based on the operation information of the external device and the assignment information of the name of the external device in the memory, the operation state of the external device is transmitted from the communication device 19 of the telemeter main body 10 to the communication device 39 of the field display unit 30. The CPU 32 displays the information on the display device 31.

[0016] In addition, the telemeter main body 10 sends information to the remote monitoring device 50 via the communication device 19. An example of the information to be sent is the information sent to the field display unit 30. Of course, other information may be added.

[0017] The communication device 19 and the communication device 39 only need to be able to realize their communication functions, including any case of wired, wireless, or a combination of both. It also includes the case of simple wiring.

[0018] Figures 2A to 2C illustrate the input information, memory allocation, and display information on the display device under normal conditions.

[0019] Figure 2A is an explanatory diagram of terminal input under normal conditions. Terminal input 21 is made to the terminal block. In a normal state, connection destination information 22A is shown, and for example, P1 to P4 are connected sequentially from left to right in the figure. P1 to P4 are all connections from external connection devices. Examples include pumps in water and sewage systems, dams, water treatment plants, and pressurized water supply stations. Of course, other monitored equipment may also be used.

[0020] In the following explanation, P1 is the signal received during normal operation of Unit 1, P2 is the signal received during a malfunction of Unit 1, P3 is the signal received during normal operation of Unit 2, and P4 is the signal received during a malfunction of Unit 2.

[0021] P1 to P4 are input as X1 to X4, respectively, as internal connection information 22B.

[0022] Figure 2B is an explanatory diagram of the memory allocation 23 under normal conditions. It is a diagram showing the electronic allocation relationships. Corresponding to X1 to X4, the external device name information 24 is allocated from left to right as WR1OK, WR1NG, WR2OK, and WR2NG.

[0023] Figure 2C shows an example of the display screen on the display device 31 in a field display unit under normal conditions. This is the case when the input from the external device matches the allocation in memory.

[0024] In that case, the correct information will be displayed in the appropriate location for the external device status 40. For this reason, the display units for Unit 1 operation, Unit 1 malfunction, Unit 2 cloud and smoke, and Unit 2 malfunction are assigned to P1 to P4 from left to right.

[0025] Therefore, for example, if a signal indicating that unit 1 has malfunctioned is received from P2, the display device 31 will show an indication such as the second indicator from the left lighting up. This allows the status of the external device to be monitored and confirmed by the telemetry device.

[0026] Figures 3A to 3C illustrate the input information, memory allocation, and display information on the display device when there is a wiring abnormality.

[0027] Typically, telemetry devices are designed to display information from external devices. This allows for monitoring of the situation without having to go directly to the installation site of equipment such as pumps. For this reason, there is usually a distance between the external device and the telemetry device.

[0028] The wiring between the external device and the telemetry device is usually left unchanged. Changes only occur during the initial wiring when the telemetry device is installed, and when the wiring is reconnected after being disconnected for construction, inspection, equipment changes, or equipment repairs.

[0029] If a wiring error occurred during this wiring process, it was traditionally necessary to physically correct the wiring, which required time and effort.

[0030] In particular, since correcting wiring requires electrical wiring work, it is common practice to establish certain official or internal qualifications and limit the work to only those who hold those qualifications.

[0031] However, this means that physically correcting the wiring requires bringing in a qualified person to perform the work. Against the backdrop of recent labor shortages, securing qualified personnel and maintaining high density of personnel is becoming difficult, creating a need to enable wiring corrections to be practically performed by non-qualified individuals.

[0032] Therefore, this invention makes it possible for general workers, not just qualified personnel, to correct misconnections by enabling them to correct the wiring virtually rather than physically.

[0033] An example of a miswiring situation will be explained using Figures 3A to 3C, corresponding to the situation shown in Figures 2A to 2C.

[0034] Figure 3A shows a state where the wiring for P1 and P3 are swapped. Due to the incorrect wiring, the information for P3 is transmitted as X1, and the information for P1 is transmitted as X3. In memory, the assignments remain WR1OK for X1 and XR2OK for X3. As a result, the display device 31 displays "Operation No. 1" despite the information being for P3. Similarly, it displays "Operation No. 2" despite the information being for P1.

[0035] Using Figures 4A to 4C, the method for recovering from a wiring error in this embodiment will be explained.

[0036] As in Figure 3A, due to the incorrect wiring, the information from P3 is transmitted as X1 and the information from P1 is transmitted as X3. However, as shown in Figure 4B, within the memory 13, the operating status information assigned to X1 and X3 is swapped, that is, WR2OK is assigned to X1 and WR1OK is assigned to X3, thereby electronically changing the incorrect wiring to the correct information connection.

[0037] As a result, as shown in Figure 4C, the display device 31 in Figure 4C will display, from left to right, "Unit 2 Operation," "Unit 1 Failure," "Unit 1 Operation," and "Unit 2 Failure," in the order corresponding to the inputs P3, P2, P1, and P4 from the left side in Figure 4A. Therefore, it becomes possible to correctly grasp the operation information of the external device on the display device 31 of the field display unit 30.

[0038] In this way, by rewriting electronic information, it becomes possible to virtually modify the wiring. Therefore, since it does not involve modifying the actual wiring, it does not require the work of a qualified professional. Furthermore, since the modification can be performed by ordinary workers, quick correction and adjustment are possible.

[0039] This modification can be achieved, for example, by using a touch panel type display as the display device 31 of the field display unit 30 and displaying a modification button 45 on it. Alternatively, it can be achieved by providing an input function that allows modification of the assignment of information between external devices and operating status.

[0040] For example, one method is to tap this modification button and change the assignment of connection destination information and external device name display by changing numerical values ​​such as the connection destination number. Alternatively, one method is to graphically display internal connection information 22B and external device name information 24 on the field display unit 30 and change the wiring relationship between the two using a touch device. Of course, other methods are also acceptable.

[0041] Figure 5A shows an example of the wiring relationships being graphically displayed on the display device 31. For example, clicking the edit button 45 on the display device 31 in Figure 3C will take you to the screen in Figure 5A. In Figure 5A, the linking relationship between the connection destination information 22A and the external device name information 24, or the assignment relationship in memory, is shown by the linking lines 60. If the field display device 30 is a touch panel device, the linking lines 60 are modified by moving the linking lines 60 with a fingertip, as shown in Figure 5B. If the field display device 30 is a PC, the linking lines 60 are modified by moving the linking lines 60 with a mouse, etc., as shown in Figure 5B. After the modification is complete, clicking the apply button 70 confirms the modification, and the linking relationships or assignment relationships are modified as shown in Figure 4B.

[0042] The corrected information is transmitted from the communication device 39 of the field display unit 30 shown in Figure 1 to the communication device 19 of the telemeter unit 10, and the CPU 12 corrects the information in the memory 13.

[0043] In this case, the CPU 12 may modify the ladder program located in memory 13 or on the CPU 12 itself.

[0044] As a result of the modifications, the remote monitoring device 50 will also be able to check the status of the external device.

[0045] In this way, by electronically correcting the assignment of information about the operating status of external devices input to the input terminals and the information displayed on the field display unit, miswiring can be quickly corrected as soon as it is discovered, and the display of the telemetering device can be restored to normal. Therefore, even if miswiring occurs, a highly convenient telemetering system can be provided that can be easily corrected.
