When the battery running out of the wireless transmitter is solved, and a normal signal is transmitted from the wireless transmitter, the data stored in the memory 29 are cleared.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an improvement in a unidirectional wireless transmission system used in a wireless monitoring system using weak waves.

[Background technology]

This type of system is configured by combining one wireless receiver and multiple wireless transmitters, and the receivers in the system are wireless transmitters attached to security sensors, fire sensors, etc. What happens when a security signal is received in the form of a radio wave signal from a portable wireless emergency transmitter carried by an elderly person walking alone or a sick person away from a caregiver? The system is configured to monitor the system without activating the J-report means or displaying the location where an abnormality has occurred on the display.

In such wireless systems, a house code is attached to the security signal sent from the transmitter, and by checking the match of this house code on the receiver side, it is possible to communicate with other wireless systems. Consideration is usually taken to prevent interference. However, since such a system generates an alarm if the house codes match, it is impossible to divide the system into multiple warning zones and activate only one of them. The flexibility in terms of use could not be said to be sufficient.

Further, in order to simplify the configuration of the conventional wireless system as described above, it is a unidirectional communication system in which a security signal is sent from the transmitter to the receiver only when an abnormality occurs. For this reason, transmission checks are not performed during normal times when no abnormalities occur, so even if an abnormality occurs in the transmission system, the abnormality cannot be discovered until actual operation is performed, and reliability is also insufficient. Ta.

Therefore, considering that the conventional wireless transmission system has problems such as ridges, the present inventors filed an application on the same day and selected a system with a wireless transmitter included in the system. proposed a wireless transmission system in which the wireless transmitter is registered as a wireless transmitter and can only process security signals from the registered wireless transmitter when in alert mode. If this happens, the alarm will be activated immediately like any other abnormal signal. However, in such a system, if the wireless transmitter runs out of battery, it will send a dead battery signal at regular intervals until the condition is restored, causing the alarm to continue ringing each time. However, if the user confirms that the battery is dead, the user operates the reset switch to stop the beeping. When such a dead battery problem occurs at night, the reset switch is often left on to release the shutdown so as not to disturb a good night's sleep. The problem arises that the

Therefore, in order to prevent such problems from occurring in the system of the present invention, if the security -1ε signal received from the receiver is a dead battery signal, the system operates the reset switch to stop the +i information device ringing, and then After that, the 7 alarm will not sound again until the predetermined set time has passed.
! It has added functionality.

[Purpose of the invention]

Therefore, an object of the present invention is to improve the wireless transmission 18 system so that it can only process security signals from registered wireless transmitters.

There is.

(Margin below) Example Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 explains an example of the use of the system of the present invention.
A indicates a wireless transmitter, and B indicates a wireless receiver.

The wireless transmitter indicated by A is available in various types depending on the purpose of monitoring the system, and all of them are equipped with a wireless transmitter and an antenna for transmitting a security signal inside the main body.

11.12 is a wireless transmitter (1) used by connecting to fire sensor Sa and security switch sb, respectively.
1 has a part of its cover cut away to expose the internal loop antenna), and the house code (described later) is included in monitoring data such as fire sensor alarms and window opening/closing detection signals. , -7 zone code, and unit code are generated, and a carrier radio wave is modulated with this data to form a security signal, which is radiated from each antenna in the form of a radio wave signal.

On the other hand, reference numerals 13 to 15 are portable wireless transmitters that are carried by people who require nursing care, such as the elderly and sick, and which transmit emergency signals by pressing pushbutton switches 13a to 15a when an emergency occurs. So, the above transmitter 11.12
A similar security signal is radiated in the form of a radio wave signal from an internal antenna.

Security signals transmitted from these wireless transmitters 11 to 15 are received by receiver B, and necessary measures for security are taken. When receiver B receives the security signal transmitted from each wireless transmitter A, it deciphers the monitoring data and takes necessary measures such as activating a TI information device (not shown). - It has an antenna 2a for receiving signals and a display section 24 for displaying security information according to the security signal received via the antenna 2a.

In addition, the monitoring data table provided in receiver B is shown in Figure 1a.
4b and the details of the display control switch.

FIG. 2 shows a schematic configuration of the internal circuit of a portable wireless transmitter A among the wireless transmitters used in the system of the present invention.

The wireless transmitter A includes a CPU10A that constitutes the main part of a one-chip microcomputer, a wireless transmitter IDB, and a house code, zone code, and unit code setting device IDC-I that consists of multiple dip switches.
DE, Operation switch SW to be pressed in case of emergency
a, and when the operation switch SWa is pressed, the CPU 10A detects this state and sends the house code to the emergency signal.

The security data (see Figure 3! q) with a zone code and unit code is sent to the wireless transmitter IDB and transmitted in the form of a radio wave signal via the antenna IDa.

Here, the house code is a unique code assigned to security and e-systems, the zone code is a unique code assigned according to the monitoring area (warning zone) of the wireless transmitter, and the unit code is a unique code assigned to each transmitter. It means.

Note that S W c is a supervisor setting switch,
By outputting a quantitative signal from wireless transmitter A to receiver B at predetermined time intervals, abnormalities in the wireless system can be detected on the receiver side. This is a tamper switch that outputs an abnormal signal when the cover to the wireless transmitter is removed.

Also, IOF is a voltage drop detector and wireless transmitter A
The device detects a voltage drop in a built-in battery (not shown) and detects a dead battery.

In the wireless transmitter A of this embodiment, the supervisor setting switch SWc allows periodic transmission of security data in a function code to be described later.

When the voltage drop detector IDE detects a dead battery, a dead battery signal with a house code, zone code, and unit code is sent from the wireless transmitter IDB in the form of a radio signal in the same way as an emergency signal. (See Figures 3a and 3b).

FIG. 3 shows an example of the structure of the signal format of the security signal transmitted from the wireless transmitter A.

In the figure, one unit of the security signal is the pause time Tk
The format is such that a burri receive Tp is provided at the beginning of two frames of data divided by Signal, battery other terms signal.

A tamper signal) is provided, followed by a function code, and finally a backup code and an odd parity check code.

The house code consists of 8 bits from H7 to HO, the zone code consists of 3 bits from 22 to ZO, the unit code consists of 3 bits from U2 to UO, and the monitoring data and function code consist of 4 bits and 2 bits, respectively. has been done.

Figure 3a shows the bit configuration diagram of the monitoring data, and Figure 3b shows the bit configuration diagram of the function code.
-53 carries information on battery exhaustion, tampering, and W alarm, respectively. When each is abnormal, "l" is loaded, and when it is normal, "0" is loaded, and the function codes FO and Fl are for periodic transmission. When the information on the presence or absence of OFF output is both omitted, “l” is placed, and when it is present, “0” is placed. Note that S3 is provided as a backup, and no information is normally sent to it.

Here, the periodic transmission function refers to the so-called supervisory function that detects abnormalities in the transmission system by transmitting signals from the wireless transmitter to the receiver side B at fixed time intervals.
FF output Regarding the output, if a wireless transmitter is attached to something like a window sensor, which outputs ON when the window is open and outputs FF when the window is closed, it will operate instantaneously like a human body detector. ○This setting is made so that the receiver B side can distinguish the difference when it is attached to a device with only N outputs, so as not to interfere with the control such as the C1 display.

In order to improve the reliability of such security signals, if an abnormality occurs in the wireless transmitter A, a 5-frame signal is transmitted from the wireless transmitter A at predetermined intervals, and a 2-frame signal is transmitted during periodic transmission. The transportation information is transmitted at predetermined time intervals.

In contrast to the wireless transmitter A having the above-described configuration, the configuration of the receiver, which is a main part of the system of the present invention, is as shown in FIG.

The basic configuration of the receiver is the same as wireless transmitter A, consisting of a combination of a microcomputer and its peripheral equipment, but in order to facilitate understanding of the system of the present invention, FIG. The configuration of the device is shown as a block diagram combining various vR function realizing means.

To explain with reference to the figure, receiver B is in registration mode,
Each mode setting switch 27.28 for switching to alert mode. Front end/decoder section 20. House code match determining means 21. ID code match determination means 23. It has a system data registration means 229 for registering any wireless transmitter A in the system, a display control switch 25, an ID code display 24a, and a monitoring data display 24b for displaying monitoring data (both shown in FIG. security information display means 24 and condition memory 29. Battery dead data determination means 3
4. It is constructed by combining a timer means 35 and a W alarm activation means 26 for driving an alarm.

Here, the dead battery data determining means 34 determines whether the security data received by the injury device is a dead battery signal, and the condition memory 29 stores the security data received by the receiver B in the order of occurrence.

In the system of the present invention, when the front end/decoder unit 20 receives and decodes the security signal from the wireless transmitter and extracts the security data, the house code match determining means 21 confirms that the house code matches, and then the ID In the code match determining means 23, I
Check the registration of the D code. In this way, only the security data for which ID code matching has been confirmed will be processed, and the alarm activation means 26 will be activated, and at the same time, the security data at that time will be stored in the condition memory 29 together with the ID code, as will be described later. is memorized.

The timer means 35 is activated when the alarm activation means 26 is reset, and if the security data received thereafter is a dead battery signal, the timer means 35 stops driving the alarm activation means 26 again, and the timer means 35 is activated. When the time is up, does it happen again? The JI [3 means 26 is driven here, and the condition memory 29 is configured to store the security data signals received by the receiver together with the ID codes in the order of occurrence.

In addition, the registration mode setting switch 27

7a, an additional charge 8, and a switch 27b.

The basic operation of the receiver B that constitutes the system of the present invention will be explained with reference to this figure. When the first IJI registration switch 27a is operated, the receiver B is set to the registration mode, and the system data registration means 22 is set to the registration mode. All registered data will be deleted.

When the first MJI registration mode is set, the security signal transmitted from the wireless transmitting WA in the form of a wave signal is received by the antenna 2a, decoded by the front end/decoder section 20, and sent here. Security data, that is, house code 1g precept zone code, unit code.

Monitoring data with a function code is retrieved (third
(see figure).

Thus, the decoded security data is manually inputted to the house code matching determination means 21, and it is determined whether the house code matches the house code set in advance in the house code setting device 21a of the reception device. is,
If the house codes match, it is determined that the security signal is from wireless transmitter A included in the system monitored by receiver B, and system data registration means 2
Registered in 2.

In this way, the security signal transmitted from the wireless transmitter A is registered in the address of the system data registration means 22 one after another each time a match of the house code is confirmed, and the security signal transmitted from the wireless transmitter A is registered in the address of the system data registration means 22 one after another. An ID code consisting of a zone and unit code will be registered.

In this way, in the first IIJI registration mode, all the data registered in the system data registration means 22 is cleared first, and all the ID codes of the wireless transmitter A received by the receiver B side are registered in the system data. However, in the other additional registration mode, only newly received ID codes of wireless originating WAs are successively registered in the system data registration means 22 without erasing the ID codes already registered in the system data registration means 22. It will be registered.

Then, registration is completed with these steps, and the registered ID is
The code can be confirmed by operating the display control switch 25 provided on the security information display means 24. That is, among the plurality of operation switches 25 provided on the security information display means 24,
Operate the scroll start switch 25a (1st a)
(see figure) Then, the ID code of wireless transmitter A registered in the system data registration means 22 is sent to the display memory (not shown), and the
In the system of the present invention, the security code having the ID code registered in the system data registration means 22 is scrolled and displayed one after another on the ID code display 24a. Since only the signal will be processed, such a scrolling display makes it easy to confirm whether the wireless transmitter A to be registered has actually been registered.

FIG. 5 shows an example of a data table constituting the system data registration means, and in the figure, zone 8. A total of 64 wireless transmitters divided into units 8
The D code can be registered along with other data.

@4 The registration of the ID code in the system data registration means 22 shown in the figure includes the function of directly registering the ID code of the wireless transmitter A, but each address in the data table in the figure 5th a Q!
L Data as shown in FIG. 5b is recorded.

In other words, in the case of accidental causes, addresses to which zones and unit codes are assigned are prepared in advance for all wireless transmitters A in the system, and all units in zones 1 to 6 have an address with a periodic transmission function. Only wireless transmitters are registered (see 5th al!!l!I!ri, I
The configuration is such that this is done by setting the registration identification flag f1 in accordance with the registration status of the D code. In addition, data f2 that specifies the presence or absence of OFF output of the wireless transmitter
can be registered as is, and furthermore, a confirmation flag f3 for periodic transmission, which will be described later, can also be set. Then, in the unit in zone 7.8, a wireless transmitter without an OFF output is registered, a corresponding registration identification flag fl is set, and data f4 defining whether or not the wireless transmitter has an OFF output is registered. Furthermore, the configuration is such that a confirmation flag f3 for periodic transmission can be set.

Note that the data f2. shown here. f4 indicates what is included in the function code included in the security data from the wireless transmitter, and flags fl and f3 are set and reset on the receiver B side.

It goes without saying that if the system of the present invention does not have a supervisory function, the registration of the data "4", the setting of the flag f3, and the reset are omitted.

When a table like the one shown in the figure is used to register the ID code, there is an advantage that the memory capacity can be reduced compared to the case where the ID code is directly registered.

The OR column for alarms 1 to U8, which is provided at the right end of the table, is used to store abnormalities in monitoring data for each zone, and is provided to send an abnormality signal to the main controller side, which will be described later, for each zone. It is something that was given.

FIG. 6 is a schematic flowchart illustrating the operation of the registration mode executed in the system of the present invention.

As mentioned above, the registration mode can be set to two types: initial registration mode and additional registration mode, and when either registration mode switch is operated, step ID0
0. In each ID01, an initial registration mode and an additional registration mode are distinguished, and if the initial registration mode is set, the process proceeds to step ID06 and all data registered in the data table 22 is erased, but if the additional registration mode is set. In this case, such table clearing is not performed and the process directly proceeds to step ID02.

Step ID02 determines the human power of the front end/decoder section 20, and if there is an input, determines whether the house code matches (step ID03).

The house code is determined by checking whether the house code of the security signal received and decoded by the front end/decoder unit 20 matches the house code preset in the receiver B. Then, the ID code of the security data is displayed on the security information display means 24 and registered in the data table 22 (steps ID04 and ID05).
), if it is determined in step ID03 that the house codes do not match, the ID code of the security data is only displayed on the security information display means 24 and is not registered in the data table 22 (step!
0071' reference).

The above-described procedure is repeated every time there is an input from the decoder section 20, and ID codes whose house codes are confirmed to match are sequentially registered in the data table 22.

Thus, after the ID code of the wireless transmitter is registered in the system data registration means 22, as described above,
The scroll start switch 25a of the display control switch 25 provided on the security information display means 24 is operated. Then, regardless of the registration order, the ID codes registered in a predetermined order are scrolled and displayed, so it can be easily confirmed whether the wireless transmitter in the target security zone has been registered.

In this case, the scroll display will be, for example, "0" if no code is registered in the e-recording mode.
” “O” and blank are displayed, and when the ID code is registered, “O” and “0” are deleted and the registered ID code is displayed. In order to facilitate this, a blank display may be inserted.

FIG. 7 shows a flowchart executed to confirm the ID code registered in the registration mode, and the data table shown in FIG. 5 is used as the system data registration means 22. step 2000
→ 2011 is a routine that executes the ID code registration motor, steps 2012, 2013 → 2019 are scroll display routines that are executed to confirm the registered ID code, and steps 2023 → 2029 are the registered I
An example diagram showing a step-up display routine executed to check the D code one by one by operating the step-up switch 25c, and steps 2032→2040 showing a step-down display routine executed by operating the step-down switch 25d. In the program, when the scroll start switch 25a is operated, the scroll display routine is executed, and the ID code display 24a displays 5! The recorded ID codes are displayed in order from the first (youngest) address. And scroll stop switch 25b1t? When the step-up switch 25c and step-down switch 25d are operated, the parameter n is incremented (indicated as Inc) and decremented (indicated as Dec), respectively, and the ID code display 24a displays the next ID code. Step-up and step-down displays are started in sequence.

In the example, the maximum value of the parameter n is 63 to match the maximum number of addresses, 64, in the data table.

(The following is a blank space) The operation of the registration mode has been described above, but in this system, when the alert mode setting switch 28 provided on the receiver B is operated, the following alert mode is executed.

An outline of the operation in this warning mode is shown in FIG. 8, so the operation in this mode will be explained with reference to this figure. When the decoder unit 200 Å force is confirmed in step 3000, in step 3001, Matching of house codes is determined in the same manner as in the registration mode. Data for which house code matching has been confirmed is processed in step 30.
In step 02, it is further determined whether the ID codes match, and the registration is confirmed. In this way, the security data whose entry has been confirmed is classified into monitoring data in steps 3003→3005, and the monitoring data is classified into warning signals (alarms),
If it is a tamper, the process proceeds to step 3009, stores the data in the condition memory 29, activates the alarm, and displays the ID code and its monitoring data on the security information display means 24 (steps 3009→301
1).

When the receiver B receives a dead battery signal for the first time, since the timer means 35 is not set at that time, the data is first stored in the condition memory 29, the alarm is activated, and the data is stored together with the ID code. The information is displayed on the security information display means 24.

When a reset operation is performed on an activated alarm, the activated alarm is immediately stopped and the timer means 35 is activated.

Here, the timer means 35 has a set time of 8 hours or more and within 24 hours.

In this way, even after the alarm has been deactivated, if the wireless transmitter sends a low battery signal, receiver B will receive this signal, but at this time the timer means has already been set. until the timer times out! Activation of the care is inhibited and the timer means 35
When the time-up occurs, the condition memory 26
The data will be stored together with the ID code.

However, since the condition memory 26 is configured not to accept the same data, the memory will not be filled with useless information.

In this way, when a signal is received and decoded by the receiver B, the data remains in the condition memory 29 unless the wireless transmitter sends a signal indicating that the battery is not running out. left behind. When the battery of the wireless transmitter is no longer exhausted and the wireless transmitter transmits a normal signal, the data stored in the condition memory 29 is cleared.

If there is an abnormality in any of the monitoring data, step 300
Proceeding to step 6, the alarm is activated, and the security information display means 24 displays its ID code and monitoring data (step 3007).

On the other hand, if the house codes match but the ID codes do not match in step 3001, the ID code of the received security signal is displayed on the ID code display (step 3008).

In a system equipped with the condition memory 29 of the present invention, the security data received from the wireless transmitter A can be stored in the order of occurrence, and read out in the order of occurrence. The cause of this can be clarified later.

FIG. 9 is a diagram showing the relationship between the condition memory and the security information display means 24. The condition memory 29 stores the monitoring data of 16 steps by its ID.
The ID code of the security data and the monitoring data are stored sequentially from steps 1 to 16 in the order in which they occur.

When reading out stored data, when a display data readout control means (not shown) is activated, step 1 is performed.
The ID code is read out sequentially from the data stored in the 7-segment display 24 provided for each zone and unit.
In a, the monitoring data is displayed by lighting up the LED display 24b corresponding to the data.

Here, among the LED indicators 24b, "A" is a warning signal (alarm), and "rT" is a tamper signal.

rLJ indicates a dead battery signal, but in a system that includes periodic transmission abnormality determining means, which will be described later, an indicator light "S" indicating periodic transmission abnormality is further provided (see FIG. 1).

The ID 121 shows an example of a flowchart that is executed when the monitoring data stored in the condition memory 29 is displayed together with the ID code.

Step 4000→40ID is the display control switch 25
The data executed when the scroll start switch 25ate is operated and stored in the memory 29 is as follows.
They are displayed one after another on the security display means 24 at 2 second intervals in the order of occurrence, and if the data is not registered,
The display will be blank. Furthermore, in order to indicate the separation of 16 steps of data, a blank display is provided after a series of registered data displays.

Steps 4011→401 show a so-called step-up display routine, in which the scroll stop switch 25b is operated and the step-up switch 25c is operated, as in the case of ID code confirmation in the registration mode. will be started. In this example, the step-up display differs from the scroll display in that the next data is sequentially stepped up and displayed.

Furthermore, steps 4019→4o25 indicate a step-down display routine that is started by operating the step-down switch 25d. Similar to the step-up display routine, this routine also has a structure in which the next data is sequentially displayed in a step-down manner.

Furthermore, by further expanding the system of the present invention, it is also possible to construct a system that can check for abnormalities in periodic transmissions to wireless transmitters.

No. 111 shows a basic configuration diagram of the system in this case, which has a configuration in which a periodic transmission abnormality determination means 30 for determining periodic transmission abnormality is added to the basic system shown in FIG.

Since the basic configuration is the same as that shown in FIG. 4, the description of the overlapping parts will be omitted, and the configuration of the periodic transmission abnormality determination means and its determination principle will be described.

To determine whether there is an abnormality in periodic transmission, the ID code of wireless transmitter A and the function code Fo (see Fig. 5b) that specifies whether periodic transmission is available are registered in the address of the system data registration means 22, and the wireless transmitter If there is a periodic transmission from A, the configuration is such that the periodic transmission confirmation flag r3 can be set as described above (see FIGS. 5 to 5b).

Then, the set state of the confirmation flag f3 is determined at intervals sufficiently longer than the periodic transmission time interval of the wireless transmitter A, and the confirmation flag f3 is then reset. The period for checking this periodic transmission can be set by a timer means, and if the wireless transmitter A to be monitored requires particularly high reliability, the number of timer means can be individually provided. If not, one timer means can be used in common.

For example, FIG. 12 shows a case where one timer means is used in common to perform the abnormality determination operation of such periodic transmission, and the setting time of the timer means is specified to be 4 hours.
The periodic transmission time interval of the wireless transmitter is shown set to 1.2 hours.

When there is a regular transmission from wireless transmitter A, the front end/decoder section 20 receives and decodes it and extracts security data. The retrieved security data is checked for house code matching by the house code match determining means 21, and is further passed to the ID code matching determining means 2.
3, it is determined whether the received wireless transmitter A is registered.

As a result of this determination, if it is confirmed that the wireless transmitter A is registered, a periodic transmission confirmation flag f3 is set in the corresponding address of the system data registration means 22, indicating that periodic transmission has occurred. Ru. In this way, wireless transmitter A performs 1. Regular transmission is performed every two hours, and the system data registration means 22 sets the regular transmission confirmation flag f3 to the corresponding address each time.

On the other hand, the regular transmission abnormality determination means 30 determines the state of the regular transmission confirmation flag f3 set in the system data registration means 22 at each set time of the timer means, that is, every time the timer means times out. That is, when the timer means times up, the system data registration means 2
The regular transmission confirmation flags f3 of the addresses specified as having periodic transmission No. 2 are referred to all at once, and when the determination of the confirmation flags f3 is completed, the set flags are reset.

At the time of such determination, if the flag has been reset, it is determined that the periodic transmission is abnormal, and the periodic transmission abnormality information and ID code are displayed on the above-mentioned security information display means 24, and at the same time, the tita activation means Necessary measures will be taken, such as activating the 911 alarm through 26. In addition, condition memory 29
In a system equipped with this system, the abnormality data (supervisor trouble) at this time is stored together with the ID code. The same figure (
(a) is the reception input of the periodic transmission sent from the wireless transmitter, (b) is the shape of the periodic transmission confirmation flag, (C)
is the abnormality determination timing by the timer means, and (d) is the periodic transmission abnormality signal (
supervisor trouble alarm) is indicated.

13 shows an example of a flowchart from 5000 to 6018 in a case where abnormality determination of regular transmission is included in execution of the warning mode.

In this program, for convenience of explanation, every time the timer times up, the address 0 of the data table 22 is
Although periodical transmission is confirmed by referring to steps 63 to 63, it goes without saying that other programs may be used to confirm the periodic transmission.

Furthermore, Figures 14(a) to (c) show the abnormality determination operation of regular transmission when one wireless transmitter is provided with one timer means (setting time is 4 hours). In this case, each time there is a reception input for periodic transmission from wireless transmitter A, the corresponding timer means is reset, so that reception is not received within the set time (4 hours) of the timer means. If not confirmed, the timer means times out and generates a supervisor trouble alarm.

6000 → 6018 in Fig. 15 is a specific usage example in which a zone 6 wireless transmitter is equipped with an individual timer means for monitoring fire sensors that require high iMH properties. This is an example of incorporating an abnormality determination routine for regular transmission into an IF command mode program.Unit codes 1 to 8 are assigned to each of the 8 wireless transmitters in zone 6, and the corresponding 4-hour timer UNIT (n) 4H is provided. 601146
018 indicates a subroutine that is executed by referring to the periodic transmission confirmation flag for each unit.

In the system of the present invention having the above-described functions, when setting the registration mode, the ID code of the wireless transmitter can be registered, and when in the alert mode, among the security signals from the wireless transmitter A received by the receiver B, the ID code of the wireless transmitter can be registered. Although it is possible to configure the system to process only those registered in the registration mode, it is also possible to set the test mode by devising a program that executes the system of the present invention.

7000 → 7021 in FIG. 16 shows the basic operation in the test mode. After completing the registration mode, operate the test mode setting switch (shown as test switch 31 in the example in FIG. 1a). Then, the alarm LED that flashes when an alarm signal is received will flash to indicate that the test mode has been entered (step 7001), and the ID code display 24a of the security information display means 24 will display the registered wireless transmitter A. ID codes are scrolled and displayed sequentially for 2 seconds (7005→7009)
. To execute this program, first read the data registered in the data table 22 into another display memory, and then read the data in this memory when displaying. When the received security signal is determined to be an alarm signal on the receiver B side after a trial transmission, the ID code is sequentially erased from the above-mentioned scroll display and the line <(7015→7021) is , the received and decoded security signal is not an alarm signal due to experimental operation,
If it is another abnormal signal (for example, a tamper signal, a dead battery signal), the alarm is activated and the abnormal data is stored in the condition memory 29 together with the ID code (7015→7020).

If you run the test mode in this way, the ID codes of wireless transmitters that are operating normally will be erased from the scroll display, and the ID codes of wireless transmitters that have not completed test operation will remain in the scroll display. left behind. In addition, as for the wireless transmitter in which an abnormality has occurred, its ID code and abnormality data are stored in the condition memory 29, making it easy to deal with abnormalities and to check operation during testing. All you have to do is test the wireless transmitter randomly with
This also has the advantage of easy maintenance.

Incidentally, in the above explanation, the configurations of the wireless transmitter A and the receiver B, which are the main components of the present invention, have been explained in detail. However, when considering the actual usage of the system of the present invention, it is necessary to install a main controller in the receiver. A connected system configuration is common.

Therefore, the following describes the system configuration when the main controller is connected to the receiver.

In configuring the system, the requirements for the main controller are to set a warning zone and to provide a display means to display abnormalities in the warning zone.In the latter case, the abnormality should not be displayed. , any configuration that can display each warning zone is fine.

FIG. 17 shows the external configuration of the main controller MC, in which warning switches 51 to 58 . Warning indicator lamps 51a to 58 that display the setting status by lighting them
a, warning lamps 51b to 58b that blink when an abnormality occurs in a zone under warning, a W caretaker 50, and a reset switch 59 for restoring the system.

In addition, in order to execute a special vigilance mode described later, home vigilance 61. A going-out warning switch 62 and corresponding operation indicator lamps 61a and 62a are provided, as well as a test mode setting switch 63 for executing the above-mentioned test mode and its indicator lamp 83a. In this example, since the receiver B is integrated into the main controller MC, the antenna 2a is provided.

FIG. 18 is a circuit configuration diagram of a group of switches provided on the main controller MC side, and FIG. 19 is a circuit configuration diagram of its display section, and the same symbols as those shown in FIG. 17 are given. The corresponding figures are shown below.

When configuring such a system, the signals processed on the receiver B side are sent to the main controller MC! Therefore, it is necessary to properly transfer data between the computer on the receiver B side and the computer on the main controller MC side.

In the system of the present invention, it is particularly important to pay attention to the case where the abnormal signal (security data) processed on the receiver B side is transmitted to the main controller MC side for display. It is necessary to consider the characteristics of the attached sensor.

As mentioned above, some of the wireless transmitters A of the present invention detect the opening and closing of a window, etc., and transmit a security signal when the window is opened and closed. , some devices transmit a detection signal as a security signal only at the moment of detection.

If such a signal is processed on the receiver B side, it can be treated as an abnormal signal as shown in -, but if it is transmitted as a signal for display to the main controller MC side, the display should match the sensor operation. In order to do so, signals specifying these types must be transmitted.

In consideration of this, in the system of the present invention, as shown in FIG. 5b, a function code is provided in the security signal transmitted from the wireless transmitter A, and the function code F
1, the two are distinguished by defining data indicating whether there is an OFF output or not. In this case, a function code with OFF output means a device configured to send an OFF signal when a window is closed, such as a window sensor, and a function code without OFF output means a sensor that sends an OFF signal when the window is closed. This means that the OFF signal is not transmitted.

When the security data with such a function code is sent from the receiver B side to the main controller MC side, on the main controller MC side,
○For those without FF output, after the security data is sent - fixed time! i-report lamps 51a-58
It is sufficient to display the alarm by lighting a, and for those with an OFF output, the alarm lamp may be kept blinking until the OFF output is received.

In addition, in the above configuration, when receiver B receives a security signal from wireless transmitter A in the alert mode, if the house codes match and registration is confirmed, the alarm is activated, and at the same time, the security signal is The ID code of the wireless transmitter that transmitted the message and the monitoring data are displayed on the display unit 24, but in an actual system, such detailed information is not necessary, and it is possible to display in which zone an abnormality has occurred. It would be good if it could be displayed depending on the operation of the sensor.

For this reason, on the main controller MC side, alarm lamps (LEDs) 51b to 58b are provided corresponding to each zone.

(Left below) Next, the necessary configuration for receiving and passing signals between the main controller MC and the receiver B will be described.

Table 1 shows the structure of a memory used as a communicator to hand over data transmitted from receiver B to main controller MC.

(Left below) As shown in Figure 1, the communicator installed on the receiver B side constitutes a 4-byte data packet, and the 2nd and 3rd bytes are sent from the receiver B gq to the main controller MC side. It constitutes a TEXT area that stores data to be sent to. The second byte is the status byte for receiver B, in which the control signal from receiver B is memorized together with the status, and the third byte is the channel byte that indicates the warning zone where the abnormality occurred. Flags Z] to Z8 are configured to be applied to FJ.

The first byte stores hexadecimal data 02, and the fourth byte is provided for checking the data of the second and third bytes.

Here, in NXTPMSG, when this flag changes from O to 1, the main controller M Cg, II can update the current message buffer that stores the message to be sent to the receiver B side, but until this flag changes from O to 1. In this case, the main controller MC side is required to continue sending the same message.

In addition, DEVICE stores the assigned address of receiver B, and RFU is an unused area, RFP
ArL is for a memory check, and when a trouble occurs in the memory on the receiver B side, the flag is set from 0 to 1.

TAMPER, LOBAT, and 5UPER1t are status flags indicating a tamper signal, a dead battery signal, and a periodic transmission abnormality, respectively. When an abnormality occurs, these flags are set.

Furthermore, flags Z1 to Z8 of zones where an abnormality has occurred are set in the channel area.

Table 2 shows the configuration of a memory for passing data from the main controller MC to the receiver B as a communicator.

(Leaving space below) As shown in Table 2, the communicator provided on the main controller MC side constitutes a 5-byte data packet, and the 2nd to 4th bytes are from the main controller MC side to the receiver B side. The second byte is the controller MC control status byte, the third byte is the bypass setting byte, and the fourth byte is the 24-hour alert setting byte. ing. The 3rd byte bypass setting and 4th byte 24-hour warning setting are for each zone 21 to Z8.
This is done by setting a flag in the bit assigned to . The first byte stores hexadecimal data 02, and the fifth byte is provided for a thumb check of the second and third bytes.

Here, in NXTPMSG, when this flag changes from 0 to 1, the receiver B side can update the current message buffer that stores the message to be sent to the controller MC, but until this flag changes from 0 to 1, Device B is required to continue sending the same message.

Also, DEVICE stores the address assigned to receiver B, and TSTMODE is a flag that is set from 0 to 1 when set to test mode, and while this flag is set, other The COMMAND bit is ignored. TMPSTORE can be bypassed or
This is to write abnormal signals generated only in the warning zone where the 4-hour warning has not been set to the temporary memory (described later), and while this flag is 1,
An abnormal signal generated only in a warning zone where bypass or 24-hour warning is not set is written into the temporary memory, but while this flag is 00, the abnormal signal is not written into the temporary memory or condition memory.
