2. Description of the Related Art Recently, a terminal device of a remote monitoring device provided in a building includes an abnormality monitoring signal of equipment of the building,
Signals for metering the amount of electricity and gas used are input, and each time a signal having a different input form is input, an input port is manufactured at an input portion of the terminal device. The number of input ports, which is the number of input points of the terminal device, determines input specifications such as, for example, 8 abnormal signal inputs and 4 pulse signal inputs, based on the size of the terminal device and the results of marketing research. Furthermore, when an order is received from a customer that does not conform to the input specifications of the terminal device, such as a shortage of input ports, a new terminal device is installed or the number of input ports is increased. Although a terminal device was manufactured and responded to quickly, the input port
It is necessary to commercialize a plurality of types of terminal devices having different numbers of points, and prepare them so that they can immediately respond to the monitoring points and meter reading points desired by customers. In addition, when a customer requests that the number of monitoring points be increased, the terminal device is replaced with a terminal device having a large number of input ports, or a board for additional input such as an abnormal signal input or a meter reading input is attached to the terminal device. Was.

[0003]

However, the conventional remote monitoring terminal apparatus has eight abnormal signal inputs and four pulse signal inputs, and another 16 abnormal signal inputs and eight pulse signal inputs. If three types of products have been commercialized, one with 50 points and the other with 50 points of abnormal signal input and 50 points of pulse signal input, the order of terminal equipment which performs 6 points of abnormal monitoring and 5 points of meter reading will be Either select the signal input of 16 points and the pulse signal input of 8 points, or add an input port board exclusively for pulse signal input to the input of 8 points of abnormal signal and 4 points of pulse signal input. In the end, even if a plurality of types of terminal devices are prepared, the cost becomes high.

[0004] It is an object of the present invention to provide a terminal device of a remote monitoring device which enables an input port to be used efficiently.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a terminal device of a remote monitoring device according to an embodiment of the present invention. The terminal device 1 and the monitoring center 2 are remotely connected via a communication line 3. This terminal device 1 has a CP
U4, a ROM 5 in which an operation program is registered, a RAM 6 in which fluidly changing data and various changeable data are registered, an input unit 7 having a plurality of input ports 7a to 7n, an external personal computer and the like. Communication port for connection
And a line controller 9 for connecting to the communication line 3 are connected by a bus line 10, respectively.
The input ports 7a and 7b are connected to contacts 11a and 11b which are closed and output an abnormal signal when an abnormality occurs in the equipment of the building (not shown). The input port 7m is connected to the building (not shown). A device 12 for outputting a pulse signal according to the amount of power used as equipment is connected, and the input port 7n is unused. The analysis result of the data input from the input ports 7a to 7n is registered in the analysis result 6a in the RAM 6, and whether the one connected to the input ports 7a to 7n is an abnormal signal input or a pulse signal input. The specification data, which is an input type determination means for identifying the ID, is registered in the specification data 6b in the RAM 6. A data setting device 14 is connected to the communication port 8 via a cable 13.
The data setting device 14 stores the specification data 6b in the RAM 6
Is configured to be rewritable.

FIG. 3 shows the data structure of the specification data 6b. The data 6ba is input to the input port 7a,
bb corresponds to the input port 7b, and similarly, data 6bn corresponds to the input port 7n, data 6bm corresponds to the pulse signal input 0xff, and data 6ba, 6bb, 6bn.

Next, the operation of the terminal device of the above-described remote monitoring device will be described with reference to the flowchart shown in FIG.
First, when data is input to any of the input ports 7a to 7n provided in the terminal device 1 in step S1, the CPU 4 reads out the specification data 6b in the RAM 6 in step S2, and inputs the data in step S3. Input type determining means for determining whether the signal is an abnormal signal input or a pulse signal input is operated. For example, when there is an input to the input port 7a, the input type determining means reads the data corresponding to the input port 7a of the specification data 6b and reads the abnormal signal input 0x00. It is determined that the input is a signal, and the process proceeds to step S4. Step S
In step 4, the CPU 4 performs an abnormal signal processing for generating abnormality occurrence information to which a building name or an abnormality occurrence time, which is the type of the abnormal signal stored in advance in the analysis result 6a of the RAM 6 corresponding to the input port 7a, is added. Activate the data processing means.

On the other hand, if the type of the signal input in step S3 is, for example, a data input to the input port 7m, the input type determining means determines the input port 7 of the specification data 6b.
Since the data 6bm corresponding to m is read to read the pulse signal input 0xff, it is determined that this input signal is a pulse signal input. Thereafter, in step S5, the data processing means stores the data in the RAM 6 corresponding to the input port 7m.
The pulse signal processing for creating pulse generation information to which the pulse signal type, the building name, and the pulse input time stored in advance in the analysis result 6a are added. The abnormality occurrence information and the pulse occurrence information created by the data processing means of the CPU 4 in steps S4 and S5 are stored in the analysis result 6a of the RAM 6 as needed in step 6. Next, in step S7, the data transmission processing determination means of the CPU 4 determines whether or not the stored data is to be transmitted to the monitoring center 2.
Perform data transmission processing.

In the case where the gas is to be read for a new need, for example, a device 11n for outputting a pulse signal corresponding to the amount of gas used is connected to an unused input port 7n, as shown in FIG. As described above, the data setting device 14 such as a personal computer or a handy terminal is connected to the communication port 8 via the cable 13, and the data 6bn corresponding to the input port 7n is set to the pulse signal input 0xff. Therefore,
Like the other ports, the input type determining means identifies whether the one connected to the input port 7n is an abnormal signal input or a pulse signal input, and is registered in the specification data 6b in the RAM 6, and Based on this, pulse signal processing is performed by the data processing means. The analysis result of the data input from the input port 7n is registered in the analysis result 6a in the RAM 6.

As described above, the data setting device 14 can set the data 6ba to 6bn of the specification data 6b corresponding to the input ports 7a to 7n to the abnormal signal input 0x00 or the pulse signal input 0xff. If the number of abnormal signal inputs and the number of pulse signal inputs are appropriately determined without distinction, the input ports 7a to 7n can be switched according to customer needs to handle both abnormal signal input and pulse signal input. As a result, the input port can be used efficiently, and it is possible to respond quickly without preparing various types of terminal devices in advance as in the prior art.

[0013]

As described above, the terminal device of the remote monitoring device according to the present invention is provided with a data setting device connected to the terminal device, and the data setting device uses the input type corresponding to each input port of the input section. Since the data of the specification data of the determination means is set to the abnormal signal input or the pulse signal input, the input port can be switched so that both the abnormal signal input and the pulse signal input can be handled. Ports can be efficiently used to meet various customer needs with a small number of models.
