Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention mainly relates to a security management system for observing and managing the health condition of a human body.

(B) Conventional technology Conventionally, this type of security management system generally uses a terminal NCU (Network Control Un).
multiple terminals called IT) and generally a center NC.
The device consists of a central management device called U, and a transmitting device (generally called an emergency button) worn by the person being managed.The terminal also sends notifications to the central management device via a general subscriber line. ing.

(c) Problems to be Solved by the Invention However, in such conventional security management systems, the calling device called the "emergency button" simply has a button and a calling function, as its name suggests. If the person wearing the device sensed something was wrong, they had to press the button themselves to be of any use.Furthermore, since the task of pressing the button was simple, false alarms were constantly occurring. However, there was a problem in that the person who received the report did not have enough information to decide what to do with the report just by knowing whether or not there was a report.Furthermore, when managing multiple managed users at the same time within the same system, abnormalities may occur. Judgment criteria were not managed individually, and if a different standard was required for a normally healthy managed person, it was necessary to set up a new management system. The challenge was how to make an appropriate report in cases where the person himself or herself made a report based on his or her own judgment, or was unable to report due to a sudden abnormality and unconsciousness. The challenge was how to manage each managed person under the same nostem at the same time.

(d) Means for Solving the Problems This invention comprises a plurality of terminals, a central management device, and a transmitting device worn by a person to be managed, and the output from the transmitting device is wirelessly reported to the terminal. In a security management system configured to send information from a terminal device to a central management device via a general subscriber line, the transmitting device is equipped with a sensor that detects the health condition of the body, and a reference range and the identity of the person to be managed in advance. a setting means for setting the hood; a means for comparing the detected value of the sensor with the set reference range;
This security management system is characterized by comprising a wireless transmission means for outputting a detected value and a managed person identification code to a terminal when the detected value is outside a reference range.

In order to accurately detect and communicate abnormal conditions of the person to be managed, the transmitting device further includes a storage means capable of inputting sensor detection values at predetermined time intervals and sequentially storing a certain number of the latest detection values. Preferably, when a predetermined number of detected values out of the stored detected values consecutively deviate from the reference range, the wireless transmission means outputs all detected values in the storage means to the terminal as abnormal data.

Further, it is desirable that the transmitting device collectively transmits data that records how the status of the person to be managed changes from normal to abnormal and from abnormal to normal for a certain period of time.

(E) Effect When the health condition of the managed person becomes abnormal and the detected value of Senna deviates from the standard range, the transmitting device wirelessly reports the detected value along with the managed person identification code from the transmitting device to the terminal, The information is sent to the central management unit via the general subscriber line. Therefore, the administrator can identify the person to be managed from the identification code and the detected value, determine the abnormal state, and take appropriate measures. For administrators, for example,
This prevents situations where the person being managed is very patient and does not report an abnormality early, or on the other hand, is anxious and reports something even though there is no abnormality, so the person being managed can always be managed under the same conditions. .

The transmitting device further includes a storage means capable of inputting the detected values of the sensor at predetermined time intervals and sequentially storing a certain number of the latest detected values, and a predetermined number of detected values among the stored detected values are consecutively stored. By outputting all detected values in the storage means to the terminal device as abnormal data when the detected value falls outside the standard range, the accuracy of detecting the health condition of the person being managed is improved and the health condition is not erroneously transmitted. Never.

In addition, if the transmitting device sends data that records the status of the person being managed for a certain period of time as it transitions from normal to abnormal and from abnormal to normal, the transmission device can change the status from normal to abnormal or from abnormal to normal. Compared to transmitting each time, the power used for starting transmission and transmitting procedures can be saved.

Furthermore, if the setting means is such that it is possible to enter and set a reference range specific to the person being managed, when managing a person who is in normal health and whose health value is different from the general health value, that value is generally considered to be abnormal. You can individually set the reference range so that it is determined to be normal if it falls within the determined range.

(f) Examples Hereinafter, the present invention will be described in detail based on examples shown in the drawings.

FIG. 1 is a system diagram of a security management system showing an embodiment of the present invention, where A is a transmitting device worn on the body of each person under management, that is, an emergency button, and B is a wireless transmitter from the emergency button A. Terminal NCU, C that receives the signal
is the center NCU that performs centralized management, and the emergency button A
The terminal NCU (13) receives the signal via the general subscriber line.

The emergency button A can take various forms such as a pendant, an armband, or a brassiere, but it preferably has a part that can come into close contact with the human body, and various sensors (pulse, body temperature, and blood pressure sensors) are attached to the part that comes in close contact with the human body. Such)
It measures heart rate, body temperature and blood pressure on a regular basis.
Every time there is a change in measured values, the data administrator (attending physician, etc.)
It is determined whether or not the value exceeds a preset normal range value, and if it is determined to be an abnormal value, the abnormal data is encoded and transmitted to the terminal NCU (B) using a chain line. Also, the terminal NCU
(B) compares the values sent several times, confirms that it is not a false alarm, and reports it to the center NCU (C) where the data administrator is located via the general subscriber line. To set the above-mentioned normal range, a removable RAM pack or IC card is used, and the reference range for each person to be managed is written in advance on them using an appropriate data input device.

The emergency button A is equipped with a button that can be pressed in the same manner as before to make a report. However, in this case, the content of the report is distinguished at the center NCU (C) by using a different code from the above-mentioned automatic report.

Further, when the emergency button A automatically reports, an alarm is sounded to prompt the person to confirm. Furthermore, equipment abnormalities and human-induced abnormalities can be managed in the same way, and it is also possible to code and report low battery voltage, out of radio coverage, going out, etc.

Fig. 2 is a perspective view showing the external appearance of the emergency button shown in Fig. 1, and this emergency button A is placed on the arm (above the elbow) of a patient who constantly needs to manage his/her physical condition or an elderly person living alone. will be installed on the 2 is a cylindrical main body made of breathable cloth, 3 is a one-chip microcomputer with a built-in transmitting circuit, 4 is an antenna embedded in the main body, and 5 is an emergency button. In addition, body layer sensor 8, blood pressure/heart rate sensor 9,
A so-called physical condition sensor such as a 1fffi sensor 7 is installed on the surface that comes in contact with the skin, that is, inside the cylindrical body 2, and an environmental sensor 6 for detecting ambient temperature and humidity is installed on the outside of the cylindrical body 2. has been done.

Note that IO is a rechargeable Dentsu.

Fig. 3 is an explanatory diagram of the internal configuration of the emergency button A, and the one-chip microcomputer 3 has a CPU II and a memory 12a-+2d.
, a wireless transmission circuit 13, an emergency button 5, an environmental sensor 6, a sweat rate sensor 7, a body temperature sensor 8, and a blood pressure/
Upon receiving the output of the heart rate sensor 9, a signal corresponding to the output is transmitted from the antenna 4. Further, the one-chip microphone 3 is driven by an electric GIO, and reference range data set in advance is inputted from a removable preset data memory (for example, a RAM pack or an IC card) 14. In this emergency button A, data obtained from each sensor at regular intervals is classified and stored in the memory 12a=I2d. In the memory 12a=I2d, data for five times obtained from each sensor is sequentially stored, the oldest data is deleted, and the new data is updated and stored. This stored data is compared with the conditions stored for each managed person in the preset data memory i4, and if it is determined that there is an abnormality, the stored data is stored in the memories 12a to 12d at that time. All data is simplified and transmitted from the radio transmission circuit 13.

Details of such operations will be explained using flowcharts shown in FIGS. 4 and 5. First, in step 101, the following process is performed when the minutes and seconds of the clock built in the one-chip microcomputer 3 are "0000", that is, once every I hour. Sensed by sensors 7 to 9, 1,000 doses, body temperature,
Heart rate, blood pressure C, etc. are measured (step 102), and the measured data are stored in the corresponding memories 122L-12d (step 103). Note that each of the memories 12a to 12d is configured to store measurement data of five consecutive times. Next, it is determined whether an abnormal state has already been detected and reported (step L04).
If no notification has been made yet, the three most recent measurement data are each compared with the reference data given from the preset data memory 14, and if any of them are abnormal (step 105), a status flag is set. An abnormality is set to (step 106), and all data is updated every 3 minutes.
times, it is sent to terminal NCU2. At this time, the detection time and data obtained from the environmental sensor 6 are also added. Then, in step 108, in the memory 12a=12d, the oldest measurement value among the five stored measurement data is discarded, and the four measurement values are sequentially shifted.
The next measurement value is stored or prepared.

Also, in step 104, if the terminal NC is already in an abnormal state.
If U(B) has been notified, if it is determined that all of the last five measurement data are normal (step 109), the status flag is set to normal (step 110), and all data are is transmitted three times in a row every three minutes as described above (step 107). And terminal NC
After determining whether or not the data is correct based on the data received three times in a row, U reports it to the center NCU (C) via the general subscriber line. Further, the functions described below are processed at any time, unlike the previous four fixed time intervals.

If the administrator presses the emergency button 5 (step 2)
01), set the button code as the notification content (step 202), and transmit all the measured data, the button code, and the time of occurrence 3 times in a row every 3 minutes (step 20).
3). Also, if the battery is exhausted (step 204), set the battery dead code in step 20.
5) Transmit all measured data, battery dead code, and occurrence time three times in a row every three minutes (step 203). In addition, if the main body 2 is removed from the managed person and then attached, the main body attachment/detachment cord must be set in step 205.
), transmits all measurement data, main unit attachment/detachment code, and occurrence time three times in succession at three minute intervals (step 203).

Further, at the terminal NCU (B), the code wirelessly transmitted from the emergency button A is converted into a code for transmission to the center NCU (C) and transmitted. When receiving the wireless signal, the level of the received carrier wave is measured, and if it is lower than a preset reference level, the out-of-range code is also transmitted from the terminal NCU (B) to the center NCU (
C). Note that, at this standard level, the out-of-radio coverage code is added to the content sent at a level that allows the code data that is still superimposed to be deciphered.

Incidentally, the measured values from each sensor are converted into corresponding codes and then stored in each memory. For example, let us explain the case of body temperature. If the body temperature is measured as 36.5°C, that value is processed as code BO6 shown in Table 1. If the body temperature is 372°C in the next measurement, it will be converted to code BO9 and processed. Codes BO5 to BO8 are determined to be normal, and codes B01 to BO4 and codes BO9 to B12 are determined to be abnormal.

Table 1 Note that in the above, a managed person identification code (ID code) is added to the data transmitted from the emergency button A.

Further, once an abnormal state is transmitted, the transmission is not performed until the next time the state returns to normal, in order to take into account the life of the battery IO. In this embodiment, the emergency button A is attached to the arm of the person to be supervised, but it may be attached to the chest from the viewpoint of ease of movement of the person and accuracy of measurement.

In this way, the administrator can constantly monitor the health condition of the person to be managed, even when not undergoing medical examination, and in the event of an abnormality, the administrator can know the progress and time of occurrence of the abnormality, so that appropriate appropriate measures can be taken.

(g) Effects of the Invention According to the present invention, the health condition of the person to be managed can be reliably monitored, and in the event of an abnormality, it is possible to take reliable measures against it.

Furthermore, there is an advantage for the person being managed that his/her physical condition can be professionally managed without him or her realizing it.

Note that the speech device further includes a storage means capable of inputting the detected values of the sensor at predetermined time intervals and sequentially storing a certain number of the latest detected values. When the values continuously deviate from the reference range, the wireless transmission means outputs all detected values in the storage means to the terminal as abnormal data, so that the health condition of the person being managed is detected with high precision and transmitted without error. .

If the transmitting device sends data that records the state of the person being managed for a certain period of time as it transitions from normal to abnormal and from abnormal to normal, the transmitting device can change the status from normal to abnormal or from abnormal to normal. 7) The power used for starting the transmission and for the transmission procedure, compared to
can be saved.

Furthermore, by providing a setting means that can input and set a reference range specific to the person being managed, when managing a person who is in normal health and whose health value is different from the general health value, the value is within the range that is generally judged to be abnormal. Since the criteria can be set individually so that even if the health condition is judged to be normal, it becomes possible to manage the health of a variety of people under management.
