Internet network 150.

A user who is requested to collect pollen scattering data or cooperates with the collection carries a sensor-equipped mobile phone 111 having a detachable sensor card. As shown in FIG. 4, for example, the sensor-equipped mobile phone 111 includes a mobile phone 41 and a pollen sensor card 45 that can be attached to the mobile phone. It can be used as a mobile phone by inserting it into a mounting part (not shown) of.

As shown in FIG. 7, the pollen sensor card 45 measures the quantity of pollen scattered in the air and converts it into an electric signal. The pollen sensor 46 processes this pollen sensor output signal into a data signal.

And a DSP 83 having the function of converting the converted voice into a digital signal or of recognizing voice.

Therefore, this mobile phone is used for ordinary calls,
Functions such as mail communication can be used in the same manner as before.

FIG. 2 shows the flow of processing in the mobile phone with a built-in sensor according to this embodiment of the present invention, and FIG. 3 shows the flow of processing in the mobile phone.

The user mounts the pollen sensor card 45 on the cellular phone 41 and starts operating the cellular phone with a built-in sensor 111 for a telephone call or mail transmission. Then, in step 301 of FIG.
As shown in (a), "Sensor card is inserted. Would you like to send data to the center?"
An inquiry is made to the user as to whether or not to transmit the data measured by the pollen sensor to the central office.

When the location where the sensor-equipped mobile phone 111 is operated is indoors or a location unsuitable for collecting pollen data, such an inquiry is not made.

In response to the inquiry in step S301, when the user transmits the measurement data by the pollen sensor, "Yes" is selected as shown in FIG. 5A, and "OK" is clicked and input.

Then, data is read from the pollen sensor card in step S302 of the flowchart of the cellular phone shown in FIG. That is, a signal to start measurement is sent from the CPU section 71 to the inserted pollen sensor card 45 as shown in FIG. 4 via the connector 70 and the connector 47, and the pollen sensor 46 measures the amount of pollen scattering. The analog data signal proportional to the pollen content of this measurement result is
Amplification and waveform processing are performed in the amplification / data processing section 48 of the sensor card, and the data signal is again input to the CPU section 71 of the mobile phone via the connector 70.

This analog data signal is converted into a digital signal in the CPU section 71 and becomes a measured value data packet signal. Then, signal processing for transmission is performed in the modulation section 72 and the high-frequency power amplification section 73, and in step S303, the antenna 74 is transmitted via the antenna sharing section 75.
From the mobile telephone exchange 110 shown in FIG. Further, the transmitted data signal is transmitted from the mobile telephone exchange 110 via the telephone company network 101 to the central office 13.
0 is sent to the central office server 135.

When the pollen amount measurement data arrives at the central office 130 and transmission is completed, the operation flow of the mobile phone is performed at step S3.
The process proceeds to step 04, where the telephone number of the callee is input, a call is started (S305), a normal call operation such as a call or mail transmission is performed, and if the call or the like is ended in step S306, the operation on the user side ends.

If the user wants to make a quick call or give priority to mail transmission in response to the inquiry in step S301, the pollen amount measurement data is transmitted by selecting "No" in FIG. 5 (a). The process proceeds to step S304 without making a call and a normal call can be made.

When the user sends an e-mail, the e-mail is created by operating the screen display of the LCD unit 80 and the key unit 81 shown in the cellular phone 41 to which the sensor card can be attached as shown in FIG. Under the control of 71, transmission processing is performed by the modulation section 72 and the high-frequency power amplification section 73, and transmitted from the antenna via the antenna sharing section 75.

Similarly, when the user talks, the audio signal digitized by the speaker / microphone 82 and the DSP 83 is controlled by the CPU 71 and the modulator 72
The transmission processing is performed by the high-frequency power amplification unit 73, and transmitted from the antenna 74 via the antenna sharing unit 75. When the user receives an e-mail or receives the other party's talk by telephone call, the reception processing is performed by the high-frequency amplification unit 76 and the demodulation unit 77 via the antenna sharing unit 75. These processes are the same as those of a normal mobile phone.

As described above, in the telephone call and the mail, the radio transmission and reception of the digital voice signal and the mail packet data are performed between the mobile telephone exchange 110 and the other mobile telephone exchange 120, for example, as in the related art. Communication with the mobile phone 123 in the service area.

On the other hand, the central office 130 executes step S201.
Are waiting to retrieve relevant data via the Internet from an organization such as a pharmaceutical company or public health center on a regular basis, and when the capturing time comes, the monitoring posts 142a to 142a-1 of the pharmaceutical company terminal 141 in step S202.
42d and the measurement data on the pollen amount from the health center terminal 145 in each area are stored in the data memory 136
And wait again.

In step S203, it is constantly monitored whether there is a report of the transmission of the measurement data from the portable terminal of the user. If there is no notification, the process returns to step S201 and obtains measurement data each time the scheduled time comes. On the other hand, step S
In 203, when the transmission report of the pollen scattering measurement data is made from the sensor-equipped mobile phone 111 carried by the user, the transmission is detected, and the process proceeds to step S204.

In step S204, the measurement data is transmitted from the user's mobile phone.

Next, in step S205, the position where the measurement data has been transmitted is detected. Mobile phone with built-in sensor 1
11 is located within the service area of the mobile telephone exchange 110 that has received and relayed the data, the position information of the sensor mobile phone 111, that is, the data collection position is specified and the data collection position information is specified. Central office 130 as
And is added and stored in the data memory 136.

In the central office 130, the server 135 or another dedicated computer (not shown) executes step S2.
At 07, the pollen amount measurement data stored in the data memory 136 is mapped to the position where the data was transmitted. For this mapping, measurement data of pollen amount at a fixed point obtained via the Internet network is also used.

Next, in step S208, the future pollen scattering state is predicted based on the map on which the measurement data is mapped, that is, the map of the current pollen scattering state. This prediction naturally refers to the current weather, temperature, and the like in the area and future weather forecasts.

Since the measurement data from the mobile phone is not transmitted at the same time, the measurement data obtained from the mobile phone is a pollen scattering state that changes with time, but the measurement data at a fixed point is also obtained. Therefore, it is possible to obtain a map of the pollen scattering status that is considerably detailed geographically and temporally, and it is possible to improve the accuracy of prediction in the future.

In step S209, the central office server 13
5 transmits the current and future pollen scattering status in the area to the mobile phone that provided the measurement data based on the geographical and temporal information described above.

In step S210, the obtained map of the future pollen scattering state is uploaded to the homepage.

For this distribution, data can be collected more effectively by providing a privilege service or the like to the user who possesses the sensor mobile phone 111 and provides the data.

As described above, according to the present embodiment, it is possible to collect measurement data from a point where no monitoring post is installed, and obtain more measurement data relating to the amount of pollen than when only the monitoring post is used. Therefore, the accuracy of grasping the current state of the pollen scattering state can be improved, and the accuracy of future prediction can be improved.

By the way, in the above-described embodiment, the case where the data processing is performed by the central office 130 of the telephone company that performs the connection business of the sensor portable telephone 111 that collects the data has been described. However, the present invention is not limited to such a case where data processing is performed in the central office.

For example, the measurement data and the transmission location data collected by the user are transferred to the pharmaceutical company terminal 141 through the dedicated line 160 connecting the central office 130 and the pharmaceutical company terminal 141 in FIG. Pharmaceutical companies that are experienced in processing data may analyze and analyze the data together with data collected from monitoring posts.

According to this embodiment of the present invention, since data analysis and analysis prediction are not performed by the central station 130, the steps following the step of receiving the measurement data from the user by the central station 130 are performed according to the flow shown in FIG. Will be

That is, the central station 130 acquires the pollen scattering measurement data from the mobile phone in step S602.
Next, the sensor mobile phone 111 from which the measurement data was obtained
Is obtained in step S603. Next step S
In step 604, transfer data is created in which the measurement data and the position information are paired to be transferred to the pharmaceutical company terminal 141 that analyzes the flying situation, and the transfer data is transferred to the pharmaceutical company terminal 141 through the dedicated line 160 in step S605. Send out.

In the pharmaceutical company terminal 141, the transmitted transfer data is stored as measurement data obtained from sources other than the monitoring posts 142a to 142d in a data memory (not shown) of the pharmaceutical company terminal 141 in step S606. I do.

On the other hand, at the pharmaceutical company terminal 141, observations are made at predetermined times by the monitoring posts 142a to 142d. If it is determined in step S607 that the predetermined time has come, in step S608,
A part of the measurement data is updated and stored in the data memory together with the data from the central office 130.

In step S609, step S2 in FIG.
Similarly to 07, the measurement data is mapped on the map in association with the position of the obtained point. Step S610
Then, the present situation of pollen scattering is analyzed based on the geographical and temporal pollen scattering measurement data stored in the data memory, and the future scattering situation is predicted. Then, step S611
In step (1), the current pollen scattering status in each region and the future prediction result in that region are transmitted to the user who sent the measurement data by e-mail.

In each of the above-described embodiments, the shortage of measurement data, such as monitoring posts, which are conventionally provided at limited locations, can be compensated for by measurement data transmitted from a mobile phone. Therefore, measurement data can be collected at many points over a wider area, which is effective in improving the quality of information provision such as current situation analysis and future situation prediction.

In the above-described embodiment, the pollen amount measured at the point of movement by the mobile phone is not limited to the mobile phone.
Of course, data measured by an HS telephone or a general mobile terminal may be sent to the central office.

In the above embodiment, the pollen amount was measured at the installation point of the monitoring post, that is, at the fixed point and the moving point by the mobile phone, and the pollen scattering state was obtained from the data. However, the pollen amount was measured only by the mobile terminal. The pollen scattering status may be obtained from the data. According to this embodiment, there is an advantage that the pollen scattering amount can be measured at a low cost without installing a device for measuring the amount of pollen at the fixed point and without having to maintain them.

Further, in the above embodiment of the present invention, the sensor information network system for measuring the pollen scattering amount has been described.
It is not limited to the amount of pollen. The measurement target of the sensor according to the present invention may be an index relating to the environment such as the amount of dust, noise, ultraviolet light, carbon dioxide, radiation, etc., or the temperature and humidity.

In collecting these measurement data, according to the present invention, the sensor information network system can be measured only by the mobile terminal, and the measurement data at the fixed point can be added as described in the above embodiment. Prediction can be performed by grasping the geographical current state and taking into account the weather forecast and the like in each region.

In the above embodiment, the position where the measurement data is obtained is specified by the area of the mobile telephone exchange. However, the means for specifying the measurement position is not limited to this.
It can be by GPS or other means. If the GPS is built into a mobile terminal such as a mobile phone and the position is specified by this GPS, the position accuracy can be further improved, and the geographical current state can be grasped and the future prediction can be further improved. .

In the present invention, the time at which the measurement data was obtained may be stored together with the measurement data and mapped as the measurement data at that time. However, when collecting and mapping measurement data at relatively short intervals, the measurement time need not be stored.

Further, in the above-described embodiment of the present invention, the future prediction is performed after the measured data is geographically mapped and analyzed. However, in the present invention, prediction may not be performed and analysis may be stopped.
