Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless security system, and more particularly, to improvement of a system in which a wireless transmitter performs regular transmission and various notifications to a wireless receiver by wireless communication.

[0002]

2. Description of the Related Art A wireless security system of this type is designed to notify a receiver of an emergency from a transmitter by radio communication. A sensor is attached to the transmitter or an emergency push button is used. On the other hand, the receiver is provided with an alarming means for informing of an emergency. Therefore, it is possible to notify the occurrence of an emergency in a receiver located at a remote place.

In such a system, when the radio wave condition is bad due to radio wave interference, or when it is erroneously used outside the guaranteed distance range for wireless communication,
It is possible that the wireless signal from the transmitter cannot be received by the receiver or cannot be received correctly. In such a case, the receiver will not be able to report the emergency even though it is an emergency, resulting in a loss of information, which is a problem related to the reliability of the system.

For this reason, in the event of a false alarm, whether there was a problem in the transmission of the alarm signal in the transmitter, a battery dead notification was transmitted from the transmitter, and an alarm was displayed in the receiver. Regardless, it is necessary to analyze whether the information was lost because it was left unattended. However, it was not easy to analyze these states. That is, since the time and contents transmitted by the transmitter are unknown, it is impossible to specify when and what kind of signal could not be received.

On the other hand, since the transmitter carries out regular transmission to the receiver, when all the transmission information and the reception information are accumulated and held in the transmitter and the receiver, the data amount is large. As a result, the cost of each device increases.

[0006]

The one-day history memory M1 is a storage means for storing and holding the presence / absence of wireless transmission as regular transmission information, notification information, and battery exhaustion information at every time from 1 to 144. Here, the time corresponds to the number of resets of the transmission timer 14, and the times 1 to 144 indicate how many times the regular transmission interval is counted from the first reset. In this example, since the regular transmission interval Ts is set to 10 minutes, 144 times correspond to one day.

The regular transmission information is 1-bit data indicating whether or not the regular transmission is performed at the immediately preceding timing, and the alert information is whether or not the alert signal is transmitted within the regular transmission interval. The battery dead information is 1 bit data indicating whether or not the battery dead notification is transmitted. All data are "1"
Indicates that there was a transmission, and "0" indicates that there was no transmission.

It indicates that the battery dead notification is transmitted at time 144. Here, for example, if the data of the one-day history memory M1 corresponds to the third day of the weekly history memory M2a, “0” is stored as the total information on the third day at the time of totaling, and the weekly supplement is added. The memory M2b stores all the information at time 3 and time 144 in the one-day history memory M1.

After that, when totaling the history data for one week, if this week corresponds to the third week of the monthly history memory M3a, "0" is displayed as the total information of the third week at the time of totaling. Auxiliary memory M3b that is stored and stored monthly
All the information in the weekly auxiliary memory M2b, that is, all the information at time 3 and time 144 on the third day is stored in. At this time, data for associating “0” of the third week of the monthly history memory M3a with the two newly stored information in the monthly auxiliary memory M3b is also stored. For example, a pointer indicating where in the monthly auxiliary memory 3b the contents of the abnormality of the third week is stored is written in the monthly history memory 3a together with "0". With such a configuration, even if there is an abnormality in a plurality of weeks in the monthly history memory 3a, it is possible to determine which information in the monthly auxiliary memory 3b corresponds to the abnormality of each week. Can be revealed.

An example of a flow chart of the operation of recording the transmission history of the wireless transmitter 1 is shown in FIGS. 7 to 9. FIG. 8 is a flowchart explaining the step (706) of totaling the memory M1 of FIG. 7 in more detail, and FIG.
8 is a flowchart illustrating in more detail the step (708) of totaling the memory M2a of FIG. 7. First, after the transmission timer 14 is started (700), it is inspected whether a warning or a dead battery has occurred (701, 702). Further, based on the output of the transmission timer 14, the regular transmission interval Ts is 1
It is checked whether 0 minutes have passed (703). As a result, if the alarm is issued, the battery is dead, or the regular transmission time Ts has elapsed, the one-day history memory M1 is updated.

If this update is an update by regular transmission, it is checked whether the time is 144 (705). That is, it is checked whether or not one day's worth of data is recorded in the one-day history memory M1, and if it has reached one day's worth, the contents of these one-day history memories M1 are totaled (706). This tabulation work checks whether there is abnormal data in the one-day history memory M1 (800), and if there is abnormal data,
All the information about the time when there is an abnormality is stored in the weekly auxiliary memory M2b (801), and "0" is written in the weekly history memory M2a as the aggregation result (802). On the other hand, if there is no abnormal data, the weekly auxiliary memory M2b is not updated, and "1" is written in the weekly history memory M2a as the aggregation result (802). After these updates,
The contents of the one-day history memory M1 are erased (803).

After the totalization (706) of the one-day history memory M1 is finished, it is checked whether it is the 7th day (707), and if it is the 7th day, the contents of the weekly history memory 2a are further totalized (708). ). This totaling work is performed by the one-day history memory M1.
Similar to the totalization (706), the week history memory M2a is checked for abnormal data (900), and if there is abnormal data, the contents of the weekly auxiliary memory M2b are stored in the monthly auxiliary memory M3b. (901), "0" is written in the monthly history memory M3a as the totalization result (902). On the other hand, when there is no abnormal data, the monthly auxiliary memory M3b is not updated and the monthly history memory M3 is not updated.
"1" is written in a as the aggregation result (902).
After these updates, the contents of the weekly history memory M2a and the weekly auxiliary memory M2b are erased (903).

When the one-day history memory M1 is updated, the transmission timer 14 is reset (709),
The presence / absence of notification is again checked (701). Next, regarding reception history data of the wireless receiver 2, FIG. 10 and FIG.
1 will be described. FIG. 10 shows an example of history data stored in the storage means 20 of the wireless receiver 2 at normal times. That is, the data of the storage means is shown when the wireless signal such as the alarm signal and the battery exhaustion notification is not received, and only the regular transmission signal is received at each regular reception interval Tr. The wireless receiver 2 receives signals from three wireless transmitters, and each transmitter is assigned a number from 1 to 3.

Therefore, the auxiliary memory 5b is one in which a part of the first storage means and a part of the second storage means are shared.

The basic history memory M4 is a storage means for storing and holding, for each wireless transmitter, whether or not a wireless signal is received within a single regular reception interval Tr, and the regular transmission information for each transmitter. , Notification information, and battery exhaustion information are stored. The regular transmission information is 1-bit data indicating whether or not the regular transmission signal is received, the alert information is 1-bit indicating whether or not the alert signal is received, and the battery dead information is This is 1-bit data indicating whether or not a battery exhaustion notification has been received. In both data, "1" indicates that the data has been received, and "0" indicates that
Indicates that it was not received.

The one-day history memory M5a has a regular reception interval T.
It is a storage unit that totals the contents of the basic history memory M4 for each r, and stores and retains only the presence or absence of abnormal data as the totalized result. If there is no abnormality, the daily history memory M5a
"1" indicating normal is stored in a predetermined position of. Here, when there is no abnormality, the regular transmission information regarding all the transmitters is “1” indicating that the transmitter has been received, and the alert information and the battery dead information regarding all the transmitters indicate that the transmitter has not been received. It refers to the case where it is “0”.

The one-day history memory M5a has 1 to 144
It is possible to store and hold the aggregation result for each time up to. In this example, since the regular reception interval Tr is 10 minutes, 144 times correspond to one day. Similarly,
When there is no abnormality in the one-day history memory M5a while the one-day transmission history is stored, "1" indicating normal is stored in a predetermined position of the weekly history memory M6. Here, the weekly history memory M6 is a storage unit that stores and holds the presence / absence data of abnormality for each day of the week.

Further, one week's worth of data is stored in the weekly history memory M6, and if there is no abnormality on any day, it indicates that it is normal at a predetermined position of the monthly history memory M7a. Is stored. Here, the monthly history memory M7a is a memory for storing abnormality existence data for each week of one month. When there is no abnormality, the transmission history is collected in this manner for each regular reception period Tr, each day, and each week, and only the result that is normal is stored in the storage means 10. ,
The amount of data held does not increase even after the period has elapsed. In this case, the auxiliary memory M5b and the monthly auxiliary memory M7b are not used.

FIG. 11 shows that when an abnormality occurs,

All the information of the auxiliary memory M5b is stored in. At this time, data for associating “0” of the third week in the monthly history memory M7a with the two newly stored information in the monthly auxiliary memory M7b is also stored. For example, a pointer indicating where in the monthly auxiliary memory 7b the abnormality content of the third week is stored is written in the monthly history memory 7a together with "0". With such a configuration, even if there is an abnormality in a plurality of weeks in the monthly history memory 7a, it is possible to determine which information in the monthly auxiliary memory 7b corresponds to the abnormality of each week. Can be revealed.

Flow charts for recording the transmission history of the wireless transmitter 1 are shown in FIGS. 12 to 14. FIG.
FIG. 3 is a flowchart explaining in more detail the updating step (1204) of the memories M5a and M5b in FIG. 12, and FIG. 14 is a flowchart explaining in more detail the totaling step (1208) in the memory M6 of FIG. .

First, after the reception timer 24 is started (120
0), it is inspected whether a periodical transmission, an alarm signal, or a wireless signal of a battery dead notification is received (1201). Upon receiving these signals, the basic history memory M4 is updated (1
202). After that, based on the output of the reception timer 24,
It is checked whether the regular reception interval Tr of 10 minutes has elapsed (1203). As a result, if the regular reception time Tr has elapsed, the contents of the basic history memory M4 are totaled (120
4).

This totaling work checks whether there is abnormal data in the basic history memory M4 (1300). If there is abnormal data, all the information in the basic history memory M4 is supplemented with a date. Stored in memory 5b (130
1), "0" is written in the one-day history memory M5a as the counting result (1302). On the other hand, if there is no abnormal data, the auxiliary memory M5b is not updated, and "1" is written as the totalization result in the one-day history memory M5a (1302). After these updates, the basic history memory M4
Is erased (1303).

Next, it is checked whether the time is 144 (1205). That is, it is checked whether or not one day's worth of data is recorded in the one-day history memory M5a, and if it has reached one day's worth, the contents of these one-day history memories M5a are totaled (1206). The totalized result is stored in the weekly history memory M6 as "0" or "1", and the one-day history memory M5 is stored.
The contents of a are deleted. In addition, in the auxiliary memory M5b,
Since the information at the time of abnormality has already been stored with a date, it is not updated.

After that, it is inspected whether it is the 7th day (120
7) On the 7th day, the contents of the weekly history memory M6 are further tabulated (1208). In this tabulation work, it is checked whether or not there is abnormal data in the weekly history memory M6a (1400), and if there is abnormal data, the contents of the auxiliary memory M5b are stored in the monthly auxiliary memory M7b (1401), “0” is written in the monthly history memory M7a as the totalization result (1402). On the other hand, if there is no abnormal data, the monthly auxiliary memory M7b is not updated, and "1" is written as the aggregation result in the monthly history memory M7a (1402). After these updates, the contents of the weekly history memory M6 and the auxiliary memory M5b are erased (1403).

When the one-day history memory M5a is updated, the reception timer 24 is reset (120
9) Then, it is checked again whether or not the wireless signal is received (1
201). By the way, the reading terminal device 3 shown in FIG. 1 is connected to the data output terminal 13 of the wireless transmitter 1 as necessary, and stores the information and the transmission timer 14 held in the storage means 10 of the wireless transmitter 1. Read the count value.
The reading terminal device 3 is configured with an internal clock (not shown), and the time of each transmission information is specified based on this internal clock.

For example, after the above-mentioned read operation has performed the 100th periodic transmission counted from the start of the timer, 100
If it is before the second periodic transmission, the information of time 100 at this time and the count value of the timer are read out, so that each transmission information can be associated with the time by performing backward calculation from the read time. . That is, if the alarm information read from the storage means is "1" at time 97, the regular transmission interval Ts is 10 minutes, and the count value of the timer at the time of reading corresponds to 8 minutes, this alarm is issued. The signal is 28
You can see that it was sent between the minute before and 38 minutes before. Further, not only the time but also the day and the week can be dealt with by performing the backward calculation in the same manner.

In exactly the same manner, the reading terminal device 3 is connected to the data output terminal 23 of the wireless receiver 2 and displays the information held in the storage means 20 of the wireless receiver 2 and the count value of the reception timer 24. It is possible to make each reception information correspond to the date and time by reading out and calculating backward from the date and time at the time of reading based on the internal clock. In this way, the wireless transmitter 1 and the wireless receiver 2
