Embodiment 1 FIG.
Embodiment 1 of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing an action definition generation device according to Embodiment 1 of the present invention.
In FIG. 1, the slave station 20 and the data processing device 30 are connected via a communication line to constitute a monitoring control system, and an input signal that is data related to a monitored device transmitted from the slave station 20 is received by the data processing device 30. Processing such as conversion and determination is performed.
The operation definition generation apparatus 10 is an apparatus for generating definition data necessary for the operation of the data processing apparatus 30, and includes an apparatus model DB (database) 1, apparatus connection information 2 (apparatus connection information database), and item process definition generation. Part 3 (signal item process definition generating means) and item process definition 4 (signal item process definition).
The device model DB1 is a database for inputting information on a device model when a unit for gathering related input signals (including dependency relationships between input signals) is patterned as a device model. 2 and the combination of FIG. Here, the unit to be patterned as a device model does not necessarily correspond to a device that actually exists, but it is generally convenient to correspond to the type of device.
The device connection information 2 is information related to an input signal that needs to be captured by the system, and has a correspondence relationship with the type of input signal and a patterned device model. For example, a combination of FIG. 4 and FIG.

The item processing definition generation unit 3 refers to the device model DB 1 and the device connection information 2 and generates an item processing definition 4 to be described later. Also, it has a function of inputting / editing the device model DB 1 and the device connection information 2 itself.
The item processing definition 4 is definition information necessary for the operation of the data processing device 30 and includes information on how to process the data received from the slave station 20. This has, for example, a configuration as shown in FIG.
The operation definition generation device 10 is configured by a computer including a storage device, and the device model DB1, the device connection information 2, and the item processing definition 4 are stored as files in the storage device.

FIG. 2 is a diagram showing an example of a device model DB of the action definition generation device according to Embodiment 1 of the present invention.
In FIG. 2, a name 1b and the number of input signals 1c are defined for each device model number 1a. In the example of FIG. 2, the number of input signals 1 c is 2 in the device model in which the device model number 1 a is 1.

FIG. 3 is a diagram showing an example of the device model DB of the action definition generation device according to Embodiment 1 of the present invention, together with FIG.
In FIG. 3, an input signal number 1i is defined for each device model number 1h, and a signal type 1j, a signal name 1k, a range switching signal 1l, a code switching signal 1m, and a failure signal 1n are defined for each input signal number 1i. Yes. This input signal number is assigned a number corresponding to the number of input signals in FIG. 2, and does not identify an actual input signal.
In FIG. 3, for each input signal number 1i of the device model number 1h, the corresponding attribute information can be read from 1j to 1n. For example, when the device model number 1h is 1 and the input signal number 1i is 1, the range switching signal 1l is 2 because it is input in the same device as the range switching signal to process this signal. This indicates that an input signal having a signal number of 2 needs to be designated. The input signal whose input signal number is 2 contains information on the range to be switched. Similarly, the code switching signal 1m is an input signal number for switching the code of the analog information, and the input signal designated here includes the code. The input signal indicated by the failure signal 1n indicates that the signal indicates a failure of the device.

FIG. 4 is a diagram showing an example of device connection information of the action definition generation device according to Embodiment 1 of the present invention.
In FIG. 4, a device number 2a that is a device to be monitored and controlled is defined, and for each device number 2a, a related device model number 2b and a device name 2c are defined.

FIG. 5, together with FIG. 4, is a diagram showing an example of device connection information of the action definition generation device according to Embodiment 1 of the present invention.
In FIG. 5, the input signal number 2i of the device model DB1 is defined for each device number 2h, and this input signal number 2i has an address when an actual input signal is transmitted from the slave station 20 to the data processing device 30. In this case, the input address 2j for specifying the input signal is associated.

FIG. 6 is a diagram showing an example of item processing definition of the action definition generation device according to Embodiment 1 of the present invention.
In FIG. 6, for each item number 4a that identifies an actual input signal, an item name 4b, an input address 4c, a corresponding device number 4d, an input signal number 4e, a range switching signal 4f, a code switching signal 4g, and a failure signal 4h Is defined. Related item numbers are associated with the range switching signal 4f, the code switching signal 4g, and the failure signal 4h.

Next, the operation will be described.
The item processing definition generation unit 3 refers to the device connection information 2 and generates an item processing definition 4 by combining information read from the device model DB 1 for the device model used therein.
For example, when the device model DB 1 is configured in FIGS. 2 and 3 and the device connection information 2 is configured in FIGS. 4 and 5, the item process definition generation unit 3 refers to the device connection information 2 in FIG. 4. It can be seen that four devices to be monitored and controlled are registered. A device whose device number 2a is 1 has a device model number 2b of 1. Referring to FIG. 5, it can be seen that there are two input signals in which the device number 2h is also 1. Then, it can be understood that this input signal may be captured at the input address 2j.

Further, the item processing definition generation unit 3 searches the device model number 2b corresponding to the device number 2h from FIG. 4, and searches the device model DB1 for a signal processing method corresponding to the device model number and the input signal number 2i. .
The item processing definition 4 is generated by combining these pieces of information. This is, for example, as shown in FIG. In FIG. 6, item numbers related to the columns of the range switching signal 4f, the sign switching signal 4g, and the failure signal 4h are defined. For example, item number D-1 is entered in the column of range switching signal 4f of item number A-1, indicating that these items are related.
In this way, by creating the device model DB1, even when installing a new device, it is possible to easily define the relationship of the input signal simply by creating new device connection information 2. .

  According to the first embodiment, the item processing definition generation unit generates an item processing definition with reference to the device model DB. Therefore, in the item definition for the same type of device, the operation of repeatedly inputting the dependency relationship between items and the like is performed. There is no need to do so, and efficiency can be improved.
