DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data collection method and a data collection device used in the health field, the medical field, the welfare field and the like. The present invention relates to a collection method and a data collection device.

[0002]

2. Description of the Related Art With the rapid aging of society in recent years, medical financing in Japan has become tight, and it is necessary to respond to this. The government will increase the burden of medical expenses on the people and, as a basic policy, shift from the conventional policy of "early detection and early treatment of illness" to "improving health to prevent illness". I'm watching.

[0003] As one of the means for effectively performing the above-mentioned "building health to prevent illness", a "health management system" has been proposed. This is measured in each household by measuring data on a health condition that can be measured in a general household (for example, a blood pressure value measured by an electronic sphygmomanometer, a body temperature measured by a thermometer, and the like, hereinafter referred to as health data). The data is transmitted to a center device installed in a medical institution or a health center via a communication network such as a public line or a CATV line by a dedicated health management terminal, and the data is analyzed / determined by an expert. Things.

[0004] According to such a health management system, daily health management at home can be performed under the guidance of a specialist, and more reliable health management can be performed. Can be expected to be reduced.

In the above-mentioned health management system, when a plurality of health management terminals and one center device are connected via a public telephone, the telephone line on the center device side is one.
In the case of a line, multiple health management terminals are connected to the center device and one
Since data is transferred by a method of making a one-to-one connection in order, the number of health management terminals that can be connected for health management is limited. For example, if the data reception time of the center device is limited to midnight 6:00 to 6:00 in the morning, the number of connected health management terminals per day of the center device is determined by the relationship with the data transmission time allocated to each health management terminal. The limit was about 50 units.

Therefore, when it is desired to connect, for example, 500 home health care terminals to one center device, a plurality of telephone lines are secured, a router is introduced, and the plurality of telephone lines are connected to the router. And the center device had to be connected. But with this method,
A plurality of telephone lines and routers must be introduced, and a plurality of telephone lines must be maintained during operation, resulting in a very large burden of introduction and maintenance costs. In addition, when introducing a health management system to individual practitioners, additional telephone line construction is required,
This was a factor that hindered the introduction of the system.

[0007]

However, in the health management system having the above-described configuration, when a plurality of health management terminals and one center device are connected via a public telephone, the center device side has a problem. If there is only one telephone line, the number of health management terminals that can be connected for health management is limited because multiple health management terminals transfer data in such a way as to make a one-to-one connection with the center device in order. There was a problem that there is. For example, if the data reception time of the center device is limited to midnight 6:00 to 6:00 in the morning, the number of connected health management terminals per day of the center device is determined by the relationship with the data transmission time allocated to each health management terminal. The limit was about 50 units.

Therefore, for example, when it is desired to connect 500 home health care terminals to one center device, a plurality of telephone lines are secured, a router is introduced, and the plurality of telephone lines are connected to the router. And the center device had to be connected. But with this method,
A plurality of telephone lines and routers must be introduced, and a plurality of telephone lines must be maintained in operation, which has a problem that the burden of introduction and maintenance costs becomes very large. Therefore, for example, when introducing a health management system to a private medical practitioner, additional telephone line construction is required, which hinders the introduction of the system.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a single line on the data receiver side without increasing the burden of introduction and maintenance costs.

In this case, a mechanism for charging a mobile phone or a PHS may be provided during an idle time such as nighttime during data transfer standby.

In the above-described configuration, the center apparatus manager divides the health management terminals 5-1 to 5-N into some groups in advance. For example, in the example shown in FIG. 4, nine terminals from the starting health management terminal 26 to the terminal health management terminal 27 belong to the group 25. Note that the number of terminals belonging to a group is not limited to this, and the number of each group does not need to be the same.

In the center apparatus 1 according to the present embodiment, at 0:00 every day at night, the circulation list generating means 1
A circulation list is automatically generated according to 0. A circulation list is generated for each group. In the circulation list, the telephone numbers of the health management terminals 26 to 30 in the group are described in the circulation order, and a circulation completed check column indicating whether the health management terminals 26 to 30 have completed circulation, that is, whether circulation has been completed. Is provided. The circulation order changes daily, and the reason and the circulation order determination method will be described later in detail. At the same time as the circulation list, a circulation table in which the health management terminals 26 to 30 store vital data and medical inquiry response data is automatically generated by the circulation table generation means 11.

First, the center apparatus 1 attempts to connect to the starting health management terminal 26 described at the top of the circulation list. If the connection is successful, transfer the circulation list and the circulation table. After transmitting the circulation list and the circulation table to a certain group, the center device 1 attempts to connect to the starting health care terminal of another group after a certain period of time has elapsed, and if the connection is successful, the circulation list and the Transfer the routing table. Do this for all groups.

The start health management terminal 26 that has received the circulation list and the circulation table via the data communication unit 19 first checks the size of the circulation table using the circulation table size determination unit 21. Size is a threshold (for example,
If it exceeds byte), the circulation is stopped. Since the circulation table is empty in the start health management terminal 26, the size does not exceed the threshold. Therefore, vital data and inquiry response data that have been measured from the data storage unit 17 and have not yet been transferred to the center device 1 are inserted into the circular table using the circular table data storage unit 22. Further, after checking that the data collection is completed by checking the check box for the own telephone number in the circulation list, the circulation list is decrypted by using the circulation list decryption means 23, Select a routing destination. Hereinafter, the same operation is repeated up to the terminal health management terminal 27.

If a certain health management terminal 28 in the group 25 tries to connect to the health management terminal 29 which is the next destination and cannot be connected, the next destination selection means 24 returns to the health management terminal 30 of the new circulation destination. Select and try to connect. Thus, even if data cannot be transmitted and received between preset terminals, the transmission of the circulation list and the circulation table does not stop.

When the health management terminal 28 receives the circulation list and the circulation table, the size of the circulation table is 200 Kbytes.
Is exceeded, the circulation table is once transferred to the center device 1 and the health management terminal 2 from which no data is collected in order to collect data that is not collected by the center device 1.
An empty circulation table in which telephone numbers 6 to 30 are described in circulation order is generated, and circulation is started again.

The terminal health management terminal 27 adds the vital data and the inquiry response data stored in its own data storage unit 17 to the circulation table, checks the circulation list, and then sends the circulation list and the circulation to the center device 1. Return the table. The center device 1 that has received the circulation list and the circulation table from the terminal health management terminal 27 stores the circulation list in the data storage unit 14 using the circulation list storage unit 12, and stores the circulation list in the circulation table using the data storage unit storage unit 13. The data is added to the data storage unit 14.

The health management terminals 26 to be circulated later
About 30, the size of the data to be circulated increases, and the communication cost and the like also increase. Therefore, by arranging the order of daily circulation at random, it is possible to prevent unfairness among the health management terminals 26 to 30 in communication cost and the like and a large load on some health management terminals 26 to 30. You may make it.

It should be noted that the present invention is not limited to the data collection method and the data collection device of the above-described embodiment, but includes, within the scope of the contents set forth in the appended claims,

The data transmitter inserts data into the circulation table in order, and the circulation table is transferred to the data receiver at the end, so that the load on the data receiver can be reduced, There is an effect that it is not necessary to perform telephone line extension work which was conventionally required when installing.

According to the second aspect of the present invention, when the data transmitter specified in the circulation list is unable to communicate, the data is transmitted to the data transmitter specified next to the data transmitter. Since the list is provided, the circulation of the circulation list does not stagnate, and the data receiver can efficiently collect data.

According to the third aspect of the present invention, the data receiver randomly changes the order of the data transmitters specified in the circulation list before giving the circulation list to the data transmitter. Therefore, if the order is changed every day, it is possible to prevent an unfair communication charge due to a difference in the amount of communication data for each data transmitter.

According to the fourth aspect of the present invention, the data transmitter that has received the circulation list determines that the total amount of data to be transmitted to the next data transmitter specified in the circulation list exceeds a predetermined threshold. If the data is too large, the data stored in the data receiver and its identifier are added to the circulation list without following the circulation list and given to the circulation list. When a certain threshold is exceeded, circulation is interrupted and the data receiver can once collect data.
This eliminates the need for each data transmitter to communicate data with enormous communication costs, and has the effect of reducing the communication cost burden on each data transmitter.

According to a fifth aspect of the present invention, a plurality of data transmitters having storage means for storing input data, and a data receiver having management means for managing data transmitted from the data transmitter. A data collection device comprising: a data receiver, a circulation list setting means for setting a circulation list in which the order of data collection is defined, and a data transmitter defined first in the circulation list. A circulation list transmitting unit for transmitting the circulation list; and a circulation list receiving unit for receiving the circulated circulation list from the data transmission unit. The data transmitter includes a circulation list receiving unit for receiving the circulation list, and a received circulation list.

The load can be reduced, and there is an effect that it is not necessary to perform a telephone line extension work which was conventionally required when installing the data receiver.

In the invention according to claim 6, the circulation list transmitting means of the data transmitter determines a new data transmitter by the determining means when the data transmitter determined by the determining means cannot transmit. Since the circulation list is transmitted to the determined data transmitter, there is an effect that the data receiver can efficiently collect the data without the circulation of the circulation list being stagnated.

According to the seventh aspect of the present invention, the circulation list setting means of the data receiver randomly changes the order of the data transmitters specified in the circulation list. If performed, it is possible to prevent an unfair communication charge due to a difference in the amount of communication data for each data transmitter.

In the invention according to claim 8, the circulation list transmitting means of the data transmitter updates the data receiver when the data amount of the updated circulation list is larger than a predetermined threshold. The circulation list is transmitted, so if the data volume of the circulation table becomes enormous during the circulation and exceeds a certain threshold, the circulation is interrupted and the data receiver can collect the data once. It works. This eliminates the need for each data transmitter to communicate data with a huge communication cost, and can reduce the communication cost burden of each data transmitter.
