As shown in FIG. 6, the data aggregating device 1A transmits a polling signal to the wireless communication devices 3A and 3B at a time interval T for one polling operation and responds from each of the wireless communication terminals 3A and 3B. The signals A1 and A2 are received. At this time, as the polling time, for example, one of two polling times generated by one polling operation is adopted.

The response signals A1 and A2 are signals generated by the data collection devices 5A and 5B, respectively.

When data is to be accumulated by the data accumulation device 1A, the control unit 12 first calls the wireless terminal 4A according to the ordinary PHS communication protocol, connects the wireless line, and connects the wireless communication device 3A to the line. The data accumulation device 1A controls the polling generation circuit 14 periodically or irregularly in the connected state to generate the polling signal PS.

In this PHS system, communication data is, for example, ADPCM (Adaptive Differential Predictive).
Coding Modulation) Converted and communicated.

Since the data collection device 5A is connected to the wireless terminal 4A, the data is transmitted to the transmission / reception unit 52 of the data collection device 5A received by the wireless terminal 4A. When the control unit 51 receives the data arriving at the wireless terminal 4a via the transmission / reception unit 52, the control unit 51 determines whether or not the data is the polling signal PS by using the polling detection circuit 55.

When the control unit 51 confirms the reception of the polling signal PS, it reads out the latest collected data stored in the collected data memory 54 and outputs the collected data to the transmission / reception unit 52 after the elapse of the time t after the polling confirmation. I do.

The collected data is sent as a response signal A1 from the transmission / reception unit 52 to the wireless terminal 4A.

In the data collection device 5A, the control unit 51
Controls the polling generation circuit 57 periodically or irregularly to generate a polling signal. The polling signal is spread-spectrum-modulated by the spreading section 59 using the spreading code SC1, and is then superimposed on the power line 6A as a spread signal. As a result, polling is performed simultaneously from the data collection device 5A to all the terminal devices 7A and 7B.

In terminal apparatuses 7A and 7B, spectrum despreading is performed on high-frequency signals in despreading sections 72 and 76, respectively. Therefore, when polling is performed from the data collection device 5A as described above, the polling signal arrives via the power line 6A as a high-frequency spread signal, so that a signal that can be despread with the spreading code SC1 is used as a polling signal. Demodulated.

The polling signals demodulated by the terminal units 7A and 7B are further supplied to terminal units 74 and 78, respectively.

When the terminals 74 and 78 confirm the polling by the polling detection circuits 74a and 78a, respectively, the terminal units 74 and 78 wait for a predetermined period of time set differently for each terminal based on the polling reception time, and then prepare the response. The signal is transmitted to the data collection device 1.

Each response signal is supplied from terminals 74 and 78 to spreading sections 73 and 77 and is spread spectrum modulated by spreading codes SC2 and SC3. Each spread signal thus obtained is superimposed on the power line 6A.

In the data collection device 5A, similarly to the terminal devices 7A and 7B, spectrum despreading is always performed on high-frequency signals in the despreading units 60 and 61. Therefore, as described above, each terminal device 7A,
When there is a response to polling sequentially from 7B, since each response signal arrives via the power line 6A as a high-frequency spread signal, a signal that can be despread spectrum by the spread codes SC2 and SC3 is demodulated as a response signal.

Each response signal thus demodulated is:
The signal is output to the multiplexing unit 62 and multiplexed there. The multiplexed data is stored in the collected data memory 54 as collected data.

As described above, according to the first embodiment, each of the data collection devices 5A and 5B and the data accumulation device 1A
Are connected to the PHS network 2A as a wireless line, and the data aggregating device 1A uses the wireless line to connect each data collection device 5A.
Since the polling signals are transmitted to the data collection devices 5A and 5B to collect the data of the data collection devices 5A and 5B, the data collection device 1A can transmit the data collection devices 5A via the wireless line from the PHS network 2A as necessary. , 5B,
As a result, it is possible to appropriately accumulate required data from a remote place.

Although the PHS network 2A is applied to the data integration system according to the first embodiment as an example of a portable telephone network, the present invention is not limited to this. For example, JDC (Japa)
n Digital Cellular), PDC (Personal Digital Cel)
lular), GSM (Global System for Mobile Communi)
Cell phone networks such as cations) are also applicable.

As described above, by using the polling signal, a plurality of data collection devices 5 can be transmitted from the data accumulation device 1A.
It is possible to request data transmission to A and 5B simultaneously.

The data collection device 5A collects data from the terminal devices 7A and 7B via the power line 6A, and the data collection device 5B collects data from the terminal devices 7C and 7C via the power line 6B.
Since data is collected from 7D, communication between the data collection device 5A and each of the terminal devices 7A and 7B and communication between the data collection device 5B and each of the terminal devices 7C and 7D need to be performed by general power lines 6A and 6B, respectively. It is not necessary to lay a new line, and an inexpensive system can be constructed as a whole.

Further, since the communication network is the PHS network 2A and the radio terminals 4A and 4B are PHS terminals for bidirectional communication with the PHS network 2A, the data collection device is provided by the bidirectional communication between the PHS network and the PHS terminal. It is possible to construct a new system for transmitting and receiving between 5A and 5B and the data accumulation device 1A.

In each of the wireless communication devices 3A and 3B, data collection is performed using spread spectrum communication, so that data can be simultaneously transmitted from the terminal devices 7A and 7B to the power line 6A. In addition, each data can be accurately extracted by the data collection device 5A. The same applies to the data collection device 5B.

In the first embodiment, each of the wireless communication devices 3A and 3B transmits data that has already been collected at the time of polling. However, data collection may be performed at the time of polling.

In this case, each of the wireless communication devices 3A and 3B
When the polling is detected, the line is temporarily disconnected, and data is collected from each of the terminal devices 7A, 7B, 7C, and 7D at this timing. Thereafter, each of the wireless communication devices 3A and 3B calls the data accumulation device 1A and transmits the collected data. At this time, each of the wireless communication devices 3A and 3B may transmit the polling time together with the collected data so that the data collecting device 1A can confirm the polling time.

The operation is performed, for example, when the data accumulating operation is performed by the data accumulating apparatus 1A, for example, the base station 2 of the PHS network 2A.
Direct wireless communication is not performed between 0A and each of the wireless communication devices 3A and 3B, and relay communication is performed by the wireless relay device 3C.

This relaying is performed because the radio waves are difficult to reach between the base station 20A and each of the radio communication devices 3A and 3B. As described above, since the wireless relay device 3C has a function as a repeater, a radio signal is amplified by the wireless relay device 3C, and wireless communication between the base station 20A and each of the wireless communication devices 3A and 3B is stabilized.

As described above, according to the second embodiment, the wireless communication device relays the wireless communication device 3A between the PHS network 2A connecting the wireless communication device 3A and the data aggregating device 1A with the wireless relay device 3C, and performs data integration. Since the device 1A transmits a polling signal to each of the wireless communication devices 3A and 3B by using the wireless line and integrates the data of each of the wireless communication devices 3A and 3B, the data aggregating device 1A becomes the wireless relay device 3C.
Thus, each of the wireless communication devices 3A and 3B can be accessed stably, whereby required data can be appropriately accumulated from a remote place.
