Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a data collection device that collects data stored in each terminal device to a center device through a telephone line or the like.

(Prior art) This type of data collection device connects a plurality of terminal devices to a center device via a telephone line, and transmits a polling signal from the center device, that is, a dial signal specifying the terminal device. After the telephone line with the terminal device is closed, the center device sends a data request to the terminal device and receives the data. Some devices perform such a data receiving operation for each terminal device to collect data from each terminal device. However, in such a device, one telephone line must be installed each time one terminal device is installed, so as the number of installed terminal devices increases, the cost of installing the telephone line becomes enormous. In order to solve this problem, it is possible to install a terminal device where a telephone is already installed and share the telephone line, but in this way, the polling signal from the center device or the call to the telephone I end up not being able to tell the difference between the two.

Therefore, in order to solve the above-mentioned problems, for example, an emergency call device that automatically sends a dial signal when an emergency situation occurs, it is necessary to send a call from a terminal device to a center every time the object to be measured changes. One possible method is to automatically send a dial signal to the device to collect data.

However, when such a method is used, in order for the center device to recognize each terminal device, a unique number or recognition code (ID No.) is given to each terminal device, and this recognition code is added to the data when transmitting data. There is a need. Therefore, the recognition code must be set and registered in the terminal device when the terminal device is manufactured, and when the terminal device is installed on-site, the recognition code must be set and registered at the time of adjustment. Therefore, when setting and registering at the time of manufacture, it is necessary to be very careful when installing the terminal device so that the terminal device is installed with the WG identification code set and registered in accordance with the position. On the other hand, if the settings are registered at the time of adjustment for on-site installation, in order to prevent mistakes in setting registration, workers should be thoroughly trained in advance on how to register the settings, etc. It is necessary to ensure that there are no differences in level. Furthermore, the structure must be such that settings cannot be easily registered by a third party and can be easily performed by an operator.

(Problems to be Solved by the Invention) As described above, it has not been possible to reliably and easily register and set the recognition code for each terminal device.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide a data collection device that can reliably and easily register and set a recognition code.

[Configuration of the Invention (Means for Solving Problems)] The present invention temporarily stores an identification code set for a terminal device in a center device, and registers the ¥ identification code upon receiving a dial signal from the terminal device. It has a function to send commands to the terminal device, and also has a function to force the terminal device to connect to the center device and receive the recognition code and registration command sent from the center device to set and register the recognition code. This is a data collection system that attempts to achieve the above objectives.

(Operation) By providing such a means, the terminal device and the center device are forcibly connected, and the center device sends a registration command together with the recognition code back to the terminal device, so that the recognition code is set and registered.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a data collection device. This device is
The center device 1 and the exchange 2.3 are connected via a communication line 4, and a plurality of transmission terminal devices (hereinafter abbreviated as terminal devices) 5-1 to 5-n are connected to the exchange 3 via a telephone line 6-. 1-5
-n. These terminal devices e5-1 to 5-n each count pulse signals from sensors 7-1 to 7-n, such as pulse-emitting power meters, and store the amount of power for each time period. There is. Note that each terminal device f5-1 to f5-n has a telephone 8.
-1 to 8-n are connected to share the telephone lines 6-1 to 6-n. Now, the center device 1 receives from the outside the recognition code to be set for each terminal device @5-1 to 5-n, temporarily stores it, and receives a dial signal from the terminal device 5-1 to 5-n. Sometimes the terminal device 5-1~5
-n has a function of sending out this Wg identification code and sending out a registration command if there is a new recognition code or recognition code to be changed.

On the other hand, each terminal device [4-1 to 4-n] is of a self-transmission type, and when the data transmission set time comes, it closes the connection with the center device 1 and later sends the data. It connects to the center device W1 and has a function of receiving the 1m code and registration command sent from the center device 1 and registering new and changed settings of the recognition code. The specific configuration is as shown in FIG. Telephone line 6-1~
For 6-n, the network control unit 9 side (data transmission) is also connected to telephone 1.
A central line switching unit 10 is provided to switch between the 8-1 and 8-n sides, and a modulation/demodulation unit 11 is connected to this central line switching unit 10 through a network control unit 9. The modulated or received signal is demodulated and sent to the main control section 12. Note that the office line switching unit 10 is normally connected to the telephones 8-1 to B-n.

Further, the pulse signals from the sensors 7-1 to 7-n are counted and stored in the data storage unit 13 as electric power worker data for each time period. Further, a time setting section 14 and a clock section 1 in which information on the data transmission setting time is set.
5 is set and when the data transmission setting time comes, the main control unit 12
The automatic dialing section 16 is operated in response to a command from the center unit 1 to transmit a dialing signal to the center unit [1].

Now, the recognition code registration section 17 has each terminal device @5-1 to 5.
A recognition code for -n has been set and registered. Each of the terminal devices 5-1 to 5-n is provided with a manual communication instruction section 18, and communication instructions sent from the manual communication instruction section 18 are sent to the main control section 12. Here, when the main control unit 12 receives this communication instruction, it forcibly connects with the center device 1, and thereby sets the recognition code in the recognition code registration unit 18 based on the recognition code and registration command sent from the center device W1. It is to be registered.

Next, the operation of the apparatus configured as described above will be explained according to the setting registration flowchart shown in FIG. The center device 1 is in a state of waiting to receive dial signals from each terminal device @5-1 to 5-n. On the other hand, each terminal device 5-1
- 5-n determine whether a communication instruction has been received from the manual communication instruction section 18 in steps S1 and S2, and further determine whether the time has reached the data transmission setting time. Here, to explain the normal data transmission operation, step S
2, when it is determined that the data transmission set time has come, in step S3, the main control section 12 of the terminal devices 5-1 to 5-n switches and connects the station line switching section 10 to the network control section 9 side, and in step S4. After determining whether a call is being made or received, in step S5, a dialing signal for the center device 1 is sent from the automatic dialing section 16, and this dialing signal is sent to the telephone line 6-1 through the network control section 9 and the office line switching section 10.
~6-n. This dial signal is then sent to the center device 1 through the exchange 3.2. Then,
Communication control is exchanged between the terminal devices 5-1 to 5-n and the center device 1, and the telephone lines between the terminal devices 5-1 to 5-n and the center device 1 are connected to the center device. When the incoming call at terminal device 1 is confirmed, in step S7, terminal device 5
-1 to 5-n transmit an identification code, for example, "0001". As a result, the terminal devices 5-1 to 5-n pass the data request signal such as the data length returned from the center device 1 through the office line switching section 10, the network control section 9, and the modulation/demodulation section 11 to the main control section 12. , and the main control unit 12 executes step s1.
Data corresponding to the data length requested at 0 is sequentially read from the data storage section 13 and transmitted to the center device 1.

Thereby, the center device 1 receives the data and stores it in a memory (not shown) together with the time period of data measurement.

Now, when installing the terminal devices 5-1 to 5-n on-site, recognition codes are set and registered for the terminal devices 5-1 to 5-n. At this time, since the mounting positions of the terminal devices 5-1 to 5-n are known, the recognition codes to be set and registered are stored in the recognition code table in the center device 1 as shown in FIG. In other words, the number of terminal devices to be installed is 5.
If it is only -1, a recognition code such as "10101 J" is stored in the area corresponding to the terminal device 5-1.

On the other hand, after installing the terminal device 5-1, the manual communication instruction section 18 is operated by the worker for a transmission test. In addition,
Before operating the manual communication instruction unit 18, the worker informs the worker on the center device 1 side that a transmission test will be performed using the telephone n8-1. Therefore, already the phone 1s-i
Since the telephone line 4 is connected to the center device 1,
The main control unit 12 moves to step S7 and controls the central office line switching unit 10 to forcibly connect the network control unit 9 to the telephone lines 6-1 to 5-n, and registers the settings in the recognition code registration unit 17. The recognized recognition code is sent to the center device 1. Since this center device 1 has received support from the worker on the center equipment W side in advance, the On code table is searched. As a result of this search, the area corresponding to the terminal device 5-1 has the Wg identification code r10.
101 J is stored, the center device 1 returns this recognition code "10101 j" to the terminal device 5-1 and also sends a registration instruction for this recognition code to the terminal device 5-1.
Send to. Note that when the center equipment +ti returns the recognition code, it erases the recognition code on the recognition code table. Now, the terminal bag 5-1 receives the recognition code in steps S8 and S9 and moves to step s12, where the main control section 12 registers the received recognition code in the vl identification code registration section 17 for new and changed settings. After this, the process moves to step s7 again and transmits the Wg identification code "10101 J" with which the new and changed settings have been registered to the center device @1. As a result, the terminal devices 5-1 to 5-n are sent to the center device @1 in the same manner as described above. Upon receiving the data request signal returned from the device@1, the data is stored in the data storage unit 13 in step s10.
The data are sequentially read out and transmitted to the center device 1. and,
The center device 1 receives the data and stores it in a memory (not shown) together with the time period of data measurement. The subsequent operation is as described above, when data is sent to the terminal device at each data transmission set time.
-1 to 5-n are sent to the center device 1.

In this way, in the above embodiment, the terminal devices 5-1 to
5-n and the center device 1 are connected in a strong $1 manner, and the center device 1 sends the registration command along with the recognition code to the terminal device 5-n.
1 to 5-n and new or changed recognition codes are set, so when installing and registering the recognition code to each terminal device 5-1 to 5-n, the installation worker must be careful about the recognition code. The installation work can be done without paying any additional fees, and there is no need to educate the installation staff on how to register the settings. Since settings can be registered from the center device 1 side, mistakes in setting registration are reduced, and each terminal device 5-1
The recognition code setting section in ~5-n becomes unnecessary. Therefore, the recognition code can be set and registered reliably and easily.

Furthermore, when the center device 1 receives a dial signal, it searches the recognition code table and can register the settings at any time if a 01 code is found.

Note that the present invention is not limited to the above-mentioned embodiment, and may be modified without departing from the spirit thereof.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a data collection device that can reliably and easily register and set an H1ffi code.
