(Eighth Embodiment) By the way, in the history information storage unit 24c described in the first embodiment, a certain action detection sensor 1
When storing the data of the detection signal for one day of a ...
If information of the detection time is added to each detection signal, the required memory capacity becomes enormous, and it is necessary to prepare the history information storage unit 24c having a large storage capacity. Therefore, in the present embodiment, a memory address space in which addresses and times correspond one-to-one is provided in the history information storage unit 24c,
The data of the detection signal is stored at the address corresponding to the detection time, and the detection time of the latest detection signal is stored. Since each detection signal does not have the information of the detection time, the detection time Need not be stored, and the required memory capacity can be reduced. The detection time of each detection signal can be specified from the address where the data is stored, and since the detection time of the latest detection signal is stored, it is possible to grasp which address data is valid. Since the basic configuration of the monitoring system is the same as that of the first embodiment, illustration and description are omitted.

Here, the memory capacity required when time information is added to each detection signal is as follows. Assuming that each of the action detection sensors 1a generates a 1-bit detection signal every minute, the data of the detection signal for one day is 1 (bits / minute) × 60 (minutes / hour) × 24 (hours). / Day) = 1440 (bits / day). Further, assuming that a memory capacity of one byte (16 bits) is used to store the detection time (hour, minute) of each detection signal, the data of the detection time for one day is 16 (bits / minute).
Minute) × 60 (minute / hour) × 24 (hour / day) = 2304
0 (bits / day). Therefore, the memory capacity required to add time information to each detection signal is 1440 + 23040 = 24480 (bits / day)
Becomes

On the other hand, in the present embodiment, as shown in the upper half of FIG. 12, a memory address space in which addresses and times correspond one-to-one is provided in the history information storage unit 24c. 00:00, 000
1H is 0: 1, 0002H is 0: 2,
An address and a time are associated with each other on a one-to-one basis, and a one-bit detection signal (for example, 1 when detection is performed and 0 when no detection is performed) is stored in each address. The lower half of FIG. 12 shows a memory address space for storing the detection time of the latest detection signal, and the detection time (year, month, day, hour,
In order to store (minutes), a memory capacity of 16 bits (year) +8 bits (month) +8 bits (day) +8 bits (hour) +8 bits (minute) = 48 bits is used. Therefore, the memory capacity required to store one day's data is a 1440-bit memory capacity for storing detection signal data and a 48-bit memory capacity for storing the latest detection signal detection time. The value obtained by adding the capacity is 1440 + 48 = 1488 (bits / day).
Approximately 1 when time information is added to each detection signal
Since only one sixth is required, the memory capacity of the history information storage unit 24c can be saved.

(Embodiment 9) By the way, in the monitoring system of Embodiment 1, when each action detection sensor 1a generates a detection signal at a predetermined time interval, the detection signal is transmitted to the monitoring device 2 sequentially. Each action detection sensor 1a
Have a large power consumption, and when a battery is used as a power source for each of the action detection sensors 1a, there is a problem that the life of the battery is shortened. Therefore, in the present embodiment, in the monitoring system of the first embodiment, each action detection sensor 1a
Are provided with a memory (storage means) for storing the history of the detection signal, and the detection signal stored in the memory is transmitted to the monitoring device 2 at regular time intervals. The reduction reduces power consumption and extends battery life. Since the basic configuration of the monitoring system is the same as that of the first embodiment, illustration and description are omitted.

FIG. 13 is a block diagram of each of the action detection sensors 1a. Each of the action detection sensors 1a has a pyroelectric sensor 11 composed of a pyroelectric sensor, a control unit 12, a memory 13,
And a wireless transmission unit 14. Then, when the detection signal is input from the pyroelectric sensor 11, the control unit 12
The detection signal is stored in the memory 13, and the detection signal for a predetermined time stored in the memory 13 at a predetermined time interval is transmitted from the transmission unit 13 by a wireless signal.

When the detection signal of the pyroelectric sensor 11 is stored in the memory 13 in each of the action detection sensors 1a, if the information of the detection time is added to each detection signal, the memory capacity of the memory 13 is increased. There is a problem that becomes large. Therefore, in the present embodiment, a memory address space in which the address and the time correspond one-to-one is provided in the memory 13, the data of the detection signal is stored in the address corresponding to the detection time, and the detection time of the latest detection signal is stored. Is stored in a predetermined address of the memory 13, and one by one
Since no detection signal has information on the detection time,
The memory capacity can be reduced. The detection time of each detection signal can be specified from the address where the data is stored, and since the detection time of the latest detection signal is stored at a predetermined address, it is possible to grasp which address data is valid. be able to.

Here, each of the action detection sensors 1a stores a 1-bit detection signal in the memory 13 every 5 seconds, and transmits the detection signals stored in the memory 13 to the monitoring device 2 at 5 minute intervals. In this case, the memory capacity required to add information of the detection time to each detection signal is as follows. That is, the data of the detection signal transmitted in one transmission is 1 (bits / piece) × 12 (pieces / piece).
(Minutes) × 5 (minutes / time) = 60 (bits / time), and once when a 1-byte (16-bit) memory capacity is used to store the detection time of each detection signal. The data of the detection time to be transmitted by the transmission is 16 (bits / bit).
Since (number) × 12 (number / minute) × 5 (minute / time) = 960 (bits / time), the memory capacity required for adding time information to each detection signal is 60 + 960 = 1.
020 (bits / time).

On the other hand, when the address of the memory 13 is made to correspond to the time on a one-to-one basis and the data of the detection signal is stored in the address corresponding to the detection time, the necessary memory capacity is set to the data of the detection signal. Is a sum of a 60-bit memory capacity for storing the detection time and a 48-bit memory capacity for storing the detection time of the latest detection signal, and 60 + 48 = 108 (bits / times) is sufficient.
About 1/9 of the case where time information is added to one detection signal
Thus, the memory capacity of the memory 13 can be saved.

Each of the action detection sensors 1a... Adds header information for communication and an error correction code (CRC) to the data of the detection signal and transmits the data. When transmitting, data of each detection signal is transmitted with header information and an error correction code added to the data. On the other hand, when the detection signal is transmitted from the action detection sensors 1a to the monitoring device 2 once every 5 minutes, the header information and the error correction code are set to 1 per 5 minutes. As a result, the data amount of transmission data can be reduced as a whole, and the transmission time can be shortened, so that power consumption can be reduced and battery life can be extended.

A memory space for storing the data of the previously transmitted detection signal is prepared in the memory 13, and the control unit 1
When the data of the detection signal stored in the memory 13 is newly transmitted, the data of the detection signal transmitted in the past may be transmitted together. For example, a memory space is provided in the memory 13 for storing data of the previously transmitted detection signal for the last 5 minutes. If the wireless transmission unit 14 transmits the data for 10 minutes including the data of the above, the data of all the detection signals is transmitted twice.

Here, when any one of the action detection sensors 1a... Transmits a detection signal to the monitoring device 2, if the detection signal is transmitted from another action detection sensor 1a. May occur and the wireless receiver 21 of the monitoring device 2 may not correctly receive the detection signal. However, each of the action detection sensors 1a... Transmits the detection signal transmitted last time at the next transmission. Is unlikely to collide twice with the detection signal from another action detection sensor 1a. Therefore, the probability that the wireless reception unit 21 of the monitoring device 2 can correctly receive the detection signal increases.

Note that the transmission interval of each action detection sensor 1a may be slightly shifted, such as 5 minutes, 5 minutes 10 seconds, 5 minutes 20 seconds, and so on. The probability of collision of the transmitted detection signal data can be further reduced, and the detection signal data can be normally received by the wireless reception unit 21 of the monitoring device 2.

As described above, the time is displayed on the display unit 3a of the mobile phone 3 in a predetermined time unit (for example, one hour unit). A first character string A1 and a second character string A5 representing the detection time during which each of the action detection sensors 1a to 1g detected the movement of a person during each time unit are displayed side by side. Here, the second character string A5 is configured by arranging different types of characters for each of the action detection sensors 1a in the order of the action detection sensors 1a... Specified in advance. The number of corresponding characters is proportional to the detection time (see Tables 2 and 3). Table 2 shows the correspondence between the location of each action detection sensor 1a ... and the type of character. The sensor installed in the living room is "*", the sensor installed in the bedroom is "b", and the sensor is installed in the toilet. Since the sensor uses "t" and the sensor installed at the entrance uses different types of characters such as "e" depending on the installation location, it is possible to grasp the location where the movement of a person is detected from the type of character. Further, the characters corresponding to the respective action detection sensors 1a are displayed in a preset order, so that the same type of characters are displayed together, so that the display on the display unit 3a can be easily viewed.

Can be grasped over time. FIG. 15 shows the contents of the e-mail in this case, and the display unit 3a of the mobile phone 3 displays a first character string A1 indicating time in a predetermined time unit (for example, one hour unit).
And a second character string A6 indicating the number of times that each of the action detection sensors 1a to 1g has detected the movement of a person during each time unit.
And are displayed side by side. Here, the second character string A6 is configured by arranging different types of characters for each of the action detection sensors 1a in the order in which the detection signals are generated.
Further, the number of characters corresponding to each of the action detection sensors 1a is between the time when one action detection sensor 1a detects the motion of a person and the time when another action detection sensor 1a detects the motion of the person. The number of characters is proportional to the number of times the action detection sensors 1a... Have generated detection signals, and the sum of the number of detections of the action detection sensors 1a to 1g in each time unit is displayed in a histogram.

Table 4 shows that the action detection sensors 1a... Between each time unit and from the time when another action detection sensor 1a. .. And the second character string A
6 shows the relationship with the number of characters. When the number of detections is 0, the number of characters in the character string A6 is 0. When the number of detections is 1 to 5, the number of characters is 1 and the number of detections is 6 to 10. , The number of characters is two, and if the number of times of detection is 11 to 15, the number of characters is three. For example, the number of characters of the second character string A6 is proportional to the number of times of detection.
