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 radio 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. , when a security signal is received in the form of a radio wave signal from a portable wireless emergency transmitter carried when an elderly person requiring nursing care is walking alone or a sick person is away from a caregiver. The system is configured to monitor the system by activating alarm means and displaying the location where an abnormality has occurred on a display. And such wireless systems include
The security signal sent from the transmitter includes
A house code is attached, and consideration is usually taken to prevent interference with other wireless systems by checking whether the house code matches on the receiver side. However, in such a system, an alarm is generated if the house codes match, so it is not possible to divide the system into multiple warning codes and activate only one code. It 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 side only when an abnormality occurs. For this reason, since a transmission check of the system is not performed, even if an abnormality occurs in the transmission system, the abnormality cannot be discovered until the actual operation is started, resulting in insufficient reliability. Therefore, in view of the problems mentioned above in the conventional wireless transmission system, the inventors of the present invention proposed a method for transmitting multiple wireless transmitters included in the system by filing an application on the same day as the present invention. Of these,
Selectively register those with registered ID codes,
Although we have proposed a wireless transmission system that can only process security signals from registered wireless transmitters during alert mode, the transmission system of the present invention further improves and extends the earlier invention. In particular, it has added a new function that allows you to run a test mode. [Object of the Invention] Therefore, the object of the present invention is to improve a wireless transmission system that can process only security signals from registered wireless transmitters; An object of the present invention is to provide a wireless transmission system with an added function that allows execution of a test mode according to a predetermined procedure in order to confirm the operation of the wireless transmission system. Another object of the present invention, in addition to the above-mentioned main object, is to provide a wireless transmitter system that is capable of simultaneously determining abnormalities in periodic transmissions when the wireless transmitter has a periodic transmission function. It is an object. [Disclosure of the Invention] In order to achieve the above object, the present invention is proposed to provide security data in which a house code, a security zone code, a unit code, and a function code are attached to monitoring data such as alarm signals emitted from sensors, etc. In a wireless transmission system that combines a plurality of wireless transmitters that output security signals in the form of radio wave signals and a wireless receiver that receives security signals from these wireless transmitters, the wireless receiver is configured to monitor Among the multiple wireless transmitters included in the system, there is a registration mode that is set to process only security signals sent from those with registered ID codes. There is a warning mode that processes only the security signal from the wireless transmitter and displays security information, as well as performs necessary processing such as activating an alarm, and an alert mode that displays the ID code registered by this registration mode. The system is configured to be able to selectively execute a test mode in which the wireless transmitter in the system is operated on a trial basis to check the operating status of the system. (b) A front-end/decoder section that extracts security data with house codes, guard zone codes, unit codes, and function codes; a mode setting switch; (c) a house code match determining means for determining whether the house code extracted from the front end/decoder unit matches a house code preset in the receiver; and (d) system monitoring. (e) system data registration means for registering at least an ID code consisting of a zone code and a unit code assigned to each wireless transmitter; Security data extracted from
(f) an ID code match determining means for comparing and referencing the ID code with an ID code already registered in the system data registering means to determine whether the ID code matches; (g) a display control switch; and (g) a display control switch; security information display means having an ID code display for displaying the ID code of the security data whose house codes have been confirmed to match, and a monitoring data display for displaying the monitoring data of the data; (h) display memory; display data readout control means for sequentially reading ID codes of the wireless transmitters registered in the system data registration means in a predetermined order and scrolling them on an ID code display of the security information display means; , display data erasing means for erasing the data read out for displaying the ID code by the display data reading display control means, and j when the registration mode is selected by the registration mode setting switch. At times, among the security signals transmitted from the wireless transmitter side, ID codes of security data whose house codes match by the house code match determining means are sequentially registered in the system data registering means; When the test mode is selected by the test mode setting switch, by executing the registration mode, the ID code registered in the system data registration means is displayed as the security information by the display data reading control means. The ID code display of the device is sequentially scrolled and displayed, and during this scrolling display, security signals are received from wireless transmitters that are activated on a trial basis, and if the house code and ID code match, it is determined that the above house code matches. If the security signal is confirmed by the means and the ID code matching determining means and further confirmed by the monitoring data determining means that the monitoring data included in the security signal is only an alarm signal, the data erasing means to erase the corresponding ID code,
The present invention is characterized in that the corresponding ID codes are sequentially erased from the scroll display. In addition, in the system of the present invention proposed to achieve another additional object, the wireless transmitter has a function code included in a security signal transmitted from the oscillator in the form of a radio wave signal. On the other hand, each time the receiver receives a security signal transmitted from the wireless transmitter, the receiver receives the security data in addition to the ID code of the security data extracted by the front end/decoder section. Periodic transmission abnormality determining means capable of registering a function code specifying the presence or absence of periodic transmission in the system data registration means, and determining an abnormality in periodic transmission from a wireless transmitter for which periodic transmission is specified based on the function code. When the receiver is set to the registration mode, the receiver registers the function code indicating the presence or absence of periodic transmission in the system data registration means together with the ID code, and when the receiver is set to the alert mode,
Every predetermined period that is sufficiently longer than the periodic transmission time interval of the wireless transmitters included in the system, the presence or absence of periodic transmission from the wireless transmitter whose function code with periodic transmission is registered in the system data registration means is checked. The transmission abnormality is determined by the transmission abnormality determining means, and when the abnormality is determined, the regular transmission abnormality is displayed together with the ID code on the security information display means. Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 explains an example of the use of the system of the present invention, in which A shows a wireless transmitter and B shows 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 security signals inside their main bodies. 11 and 12 are wireless transmitters used by connecting to the fire sensor Sa and security switch Sb, respectively (the cover of 11 is shown with a portion of its cover cut away to expose the internal loop antenna). ), the house code, which will be described later, is added to monitoring data such as fire sensor alarms and window opening/closing detection signals.
Security data with a warning zone code and unit code is 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 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 in the event of an emergency. , a security signal similar to that of the transmitters 11 and 12 described above is radiated in the form of a radio wave signal from an internally provided 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 decodes the monitoring data and takes necessary measures such as activating an alarm (not shown). It has an antenna 2a for receiving, and a display section 24 for displaying security information according to the security signal received via the antenna 2a. Note that FIG. 1a shows details of the monitoring data display 24b and display control switch provided in the receiver B. 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 CPU 10A that constitutes the main part of a 1-chip microcomputer, and
It has a wireless transmitter 10B, house code, zone code, and unit code setting devices 10C to 10E consisting of a plurality of deep switches, and an operation switch SWa that is pressed in an emergency.When the operation switch SWa is pressed, the CPU 10A
detects this condition and sends a house code to the emergency signal.
Security data (see FIG. 3) with a zone code and unit code attached is sent to the wireless transmitter 10B and transmitted in the form of a radio wave signal via the antenna 10a. Here, the house code is a unique code assigned to the security system, the zone code is a unique code assigned according to the monitoring area (alarm zone) of the wireless transmitter, and the unit code is a unique code assigned to each transmitter. It means code. Note that SWc is a supervisory setting switch that enables the receiver side to detect abnormalities in the wireless system by outputting regular signals from wireless transmitter A to receiver B at predetermined time intervals. Further, SWb is a tamper switch provided as necessary, and outputs an abnormal signal when the cover of the wireless transmitter A is removed. Further, 10F is a voltage drop detector that detects a voltage drop in a battery (not shown) built into the wireless transmitter A, and detects a dead battery. In the wireless transmitter A of this embodiment, the presence or absence of periodic transmission of security data can be set in the function code described later by the supervisor setting switch SWc, and the voltage drop detector 10F
When detects a dead battery, the house code,
The wireless transmitter 10B transmits a low battery signal with a zone code and a unit code in the form of a radio wave signal in the same manner as an emergency signal (see FIGS. 3a and 3b). FIG. 3 shows an example of the signal format of the security signal transmitted from the wireless transmitter A. In the figure, one unit of the security signal is a format in which a pre-receive Tp is provided at the beginning of two frames of data separated by a pause time Tk, and each frame has the above-mentioned house code,
After the zone code and unit code, signals that serve as monitoring data (for example, alarm signal, dead battery signal, tamper signal) are provided, followed by a function code, and finally a backup code and an odd parity check code. It is said that the configuration includes the following. The house code is 8 bits from H7 to H0, the zone code is 3 bits from Z2 to Z0, and the unit code is from U2 to U0.
It has a 3-bit configuration, and the monitoring data and function code have a 4-bit and 2-bit configuration, respectively. Figure 3a is a bit configuration diagram of monitoring data, Figure 3b
The figure shows the bit configuration diagram of the function code, and the monitoring data S0 to S3 contain information on dead battery, tamper, and alarm, respectively.When each is abnormal, the data is "1" and when it is normal, it is "0". In the function codes F0 and F1, information on the presence or absence of periodic transmission and the presence or absence of OFF output is placed.If both are absent, "1" is placed, and when there is, "0" is placed. Note that S3 is provided as a backup, and no information is normally sent to it. Here, the presence of periodic transmission means a so-called supervision function that transmits a signal from the wireless transmitter A to the receiver side B at fixed time intervals to detect abnormalities in the transmission system, and the presence of OFF output means the so-called supervision function that detects abnormalities in the transmission system. For example, when a wireless transmitter is attached to a device such as a window sensor that outputs an ON output when the window is opened and an OFF output when the window is closed, or when attached to a device that only has an ON output that operates instantaneously, such as a human body detector. By making it possible for receiver B to distinguish between cases where
This is set to ensure that there are no problems with display control, etc. In order to improve the reliability of such security signals, if an abnormality occurs in wireless transmitter A, 5 frames of signals are transmitted from wireless transmitter A at predetermined intervals, and 2 frames are transmitted during periodic transmission.
Frame signals are transmitted continuously 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 wireless transmitter A.
Similarly, the receiver is configured by combining a microcomputer and its peripheral equipment, but in order to make it easier to understand the system of the present invention, the configuration of the receiver is shown in Fig. 4 as a block diagram that combines means for realizing each function. Shown as a diagram. To explain with reference to the figure, the receiver B includes mode setting switches 27 and 28 for switching between registration mode and warning mode, a front end/decoder section 20, a house code matching determination means 21,
It has an ID code match determination means 23, a system data registration means 22 for registering any wireless transmitter A in the system, a display control switch 25, an ID code display 24a, and a monitoring data display for displaying monitoring data. security information display means 24, monitoring data discrimination means 34, display data erasing means 36, display data reading control means 35,
It is constructed by combining a display memory 37 and an alarm activation means 26 for driving an alarm. The registration mode setting switch 27 is divided into an initial registration switch 27a and an additional registration switch 27b to realize initial registration and additional registration, which will be described later. 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 initial registration switch 27a is operated, the receiver B is set to the registration mode and is registered in the system data registration means 22. All existing data will be erased. When this initial registration mode is set, the security signal transmitted from the wireless transmitter A in the form of a radio wave signal is sent to the antenna 2a.
The data is received by the front end/decoder unit 20, and security data, that is, monitoring data with house codes, security zone codes, unit codes, and function codes, is extracted (see Figure 3). . Thus, the decoded security data is input to the house code matching determination means 21,
It is determined whether the house code matches the house code set in advance in the house code setting device 21a on the receiver side, and if the house code matches, the house code is included in the system monitored by receiver B. The system data registration means 22
will be registered. In this way, the security signal transmitted from 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 wireless transmitter A is registered in the address of 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 initial 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 on the receiver B side are stored in the system data registration means 22. However, in the other additional registration mode, only the newly received ID codes of wireless transmitter A are registered one after another without erasing the ID codes already registered in the system data registration means 22. It will be registered. After completing the registration through these steps, if you want to check the registered ID code, press the display control switch 2 provided on the security information display means 24.
This can be done by operating 5. That is, among the plurality of operation switches 25 provided on the security information display means 24, the scroll start switch 25a is operated (see FIG. 1a). Then, the ID code of the wireless transmitter A registered in the system data registration means 22 is sent to a display memory (not shown), and the ID codes are scrolled and displayed one after another on the ID code display 24a in descending order. It turns out. In the system of the present invention, when executing the alert mode to be described later, the information registered in the system data registration means 22 is
Since only the security signal having the ID code will be processed, such scrolling display allows easy confirmation of whether the wireless transmitter A to be registered has actually been registered. FIG. 5 shows an example of a data table that constitutes the system data registration means.
ID codes for a total of 64 wireless transmitters divided into Zone 8 and Unit 8 can be registered along with other data. Although the ID code registration in the system data registration means 22 shown in FIG. 4 includes a function of directly registering the ID code of wireless transmitter A, each of the data tables in the example Data as shown in FIGS. 5a and 5b are recorded in the address. That is, in the example shown, addresses to which zone 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 the periodic transmission function enabled. Only certain wireless transmitters are registered (see FIG. 5a), and the ID code is registered by setting the corresponding registration identification flag f1. Furthermore, the configuration is such that data f2 defining whether or not the wireless transmitter outputs OFF can be registered as is, and furthermore, a confirmation flag f3 for periodic transmission, which will be described later, can be set. Then, in the units of zones 7 and 8, wireless transmitters without OFF output are registered, a corresponding registration identification flag f1 is set, and data f4 defining whether or not the wireless transmitter has 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 and f4 shown here indicate what is included in the function code included in the security data from the wireless transmitter, and the flags f1 and f3 are set on the receiver B side. It will be reset. It goes without saying that if the system of the present invention does not have a supervisory function, the registration of data f4 and the setting and resetting of flag f3 are omitted. When using a table like the one shown in the figure for registering ID codes, it has the advantage of reducing memory capacity compared to registering ID codes directly. The OR column for alarms U1 to U8 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 for each zone, which will be described later. 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 modes: initial registration mode and additional registration mode, and when either registration mode switch is operated, in steps 1000 and 1001 respectively,
The initial registration mode and the additional registration mode are distinguished, and if the initial registration mode is set, the process advances to step 1006 and all data registered in the data table 22 is erased, but when the additional registration mode is set, such table clearing is not done,
Proceed directly to step 1002. In step 1002, the input to the front end/decoder section 20 is determined, and if there is an input, it is determined whether the house code matches (step 1003). The house code is determined by checking whether the house code of the security signal received and decoded by the front end/decoder section 20 matches the house code preset in the receiver B. If they match, the security data ID
The code is displayed on the security information display means 24 and registered in the data table 22 (steps 1004 and 1005), but if it is determined in step 1003 that the house code does not match, the ID code of the security data is It is only displayed on the display means 24 and is not registered in the data table 22 (see step 1007). The above-described procedure is repeated every time there is an input from the decoder unit 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, the security information display means 24 is displayed as described above.
2. Operate the scroll start switch 25a of the display control switch 25 provided in the display control switch 25. Then, regardless of the registration order, ID codes registered in a predetermined order are scrolled and displayed, making it easy to confirm whether the wireless transmitter in the target security zone has been registered. In this case, if the ID code is not registered depending on the registration mode, the scroll display will be as follows:
For example, it can be configured to display blanks as "0" and "0", and when an ID code is registered, "0" and "0" are erased and the registered ID code is displayed. In order to easily display the completion of the sequence, a blank display may be inserted. Figure 7 shows the ID registered by registration mode.
This is a flowchart that is executed to check the code, and the system data registration means 22
For this purpose, the data table shown in FIG. 5 is used. Step 2000→2011 is a routine that executes ID code registration mode, and step 2012,
2013→2019 is a scroll display routine and step executed to confirm the registered ID code.
Steps 2023→2029 indicate a step-up display routine executed to confirm the registered ID code one by one by operating the step-up switch 25c, and steps 2032→2040 indicate a step-down display routine executed by operating the step-down switch 25d. . In the program shown in the example diagram, when the scroll start switch 25a is operated, the scroll display routine is executed, and the registered ID codes are displayed in order from the first (younger) address on the ID code display 24a. .
Then, when the scroll stop switch 25b is operated, the step-up switch 25c, and the step-down switch 25d are operated, the parameter n is incremented (indicated as Inc) and decremented (indicated as Dec), respectively.
The ID code display 24a is arranged so that step-up and step-down display starts sequentially from the next ID code. In the example, the parameter n is set to a maximum of 63 to match the maximum number of addresses, 64, in the data table. The operation in the registration mode has been described above, but in this system, when the alarm mode setting switch 28 provided on the receiver B is operated, the following alarm 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 input of the decoder unit 20 is confirmed in step 3000, the operation in step 3001 is as follows.
In this case, matching of house codes is determined in the same manner as in the registration mode. For the data whose house codes have been confirmed to match, in step 3002, it is further determined whether the ID codes match, and registration is confirmed. In this way, the security data whose registration has been confirmed is classified into monitoring data in steps 3003→3005, and if there is an abnormality in any of the monitoring data,
Proceeding to step 3006, the alarm is activated and the security information display means 24 displays the alarm.
ID code and monitoring data are displayed (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). FIG. 9 shows a further expansion of the system of the present invention, in which a condition memory 2 stores monitoring data together with an ID code each time a security signal is received from a wireless transmitter A.
9 is shown. In a system provided with such a condition memory 29, information on the occurrence of abnormality in the system is stored, so that the cause of theft or fire can be determined later. In a system including such a condition memory 29, the security data received from the wireless transmitter A is
It is desirable to store the information in the order in which it occurs, and to read it out in the order in which it occurs. FIG. 10 is a diagram showing the relationship between the condition memory and the security information display means 24. The condition memory 29 is designed to store 16 steps of monitoring data together with its ID code. Security data ID
Codes and monitoring data are stored sequentially from steps 1 to 16 in the order in which they occur. When reading the stored data, when the display data reading control means (not shown) is activated, the data stored in step 1 is read out in order, and the ID code is displayed on the 7-segment display 24a provided for each zone and unit. 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), "T" is a tamper signal, and "L"
indicates a dead battery signal, but in a system that includes a periodic transmission abnormality determining means, which will be described later, an indicator light "S" indicating a periodic transmission abnormality is further provided (see FIG. 1). FIG. 11 shows an example of a flowchart executed when the monitoring data stored in the condition memory 29 is displayed together with the ID code. Step 4000 → 4010 is the display control switch 25
The data executed when the scroll start switch 25a is operated and stored in the memory 29 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. In addition, a blank display is provided after a series of registered data displays to indicate the separation of 16 steps of data. Further, steps 4011→4018 indicate a so-called step-up display routine, which is started by operating the scroll stop switch 25b and the step-up switch 25c, as in the case of ID code confirmation in the registration mode. be done. In this example, the step-up display is different from the scroll display in that the next data is sequentially stepped up and displayed. Further, steps 4019→4025 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 possible to construct a system that can check for abnormalities in the periodic transmission of wireless transmitter A. FIG. 12 shows a basic configuration diagram of the system in this case, in which the condition memory 29 described above is added to the basic system shown in FIG. The configuration includes a means 30. Since the basic configuration is the same as that shown in FIGS. 4 and 9, 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 abnormality in regular transmission, enter the ID of wireless transmitter A in the address of system data registration means 22.
Along with the code, a function code Fo (see Figure 5b) that specifies whether periodic transmission is available is registered, and if there is periodic transmission from wireless transmitter A, the periodic transmission confirmation flag f3 can be set as described above. (See Figures 5 to 5b).
Then, the above-mentioned confirmation flag f
3 is set, and then the confirmation flag f3 is set.
Reset. The period for checking this periodic transmission can be set using a timer means, and if the wireless transmitter A to be monitored requires particular reliability, the number of timer means can be individually provided. If this is not required, a configuration may be adopted in which one timer means is used in common. For example, FIG. 13 shows a case in which a single timer means is used in common for the abnormality determination operation of such periodic transmission, and the setting time of the timer means is specified as 4 hours, and The transmission time interval 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 matching determining means 21, and is further checked by the ID code matching determining means 23.
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, the wireless transmitter A performs regular transmission every 1.2 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 every set time of the timer means, that is, every time the timer means times out. That is, when the timer means times up, it refers all at once to the periodic transmission confirmation flag f3 of the address specified as having periodic transmission in the system data registration means 22, and when the determination of the confirmation flag f3 is completed, the set flag is reset. do. 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 security information display means 24, and at the same time, the alarm activation means is displayed. 26, necessary processing such as sounding the sound alarm will be performed. Furthermore, in a system provided with the condition memory 29, abnormal data (supervisor trouble) at this time is stored together with the ID code. Figure 13 shows the logical operation for determining an abnormality in the periodic transmission of a particular wireless transmitter, where a shows the reception input of the periodic transmission sent from the wireless transmitter, and b shows the periodic transmission confirmation. The state of the flag, c indicates the abnormality determination timing by the timer means, and d indicates the periodic transmission abnormality signal (supervisor trouble alarm) generated when abnormality is determined in periodic transmission. 5000→5018 in FIG. 14 shows an example of a flowchart when abnormality determination of regular transmission is incorporated during execution of the warning mode. For convenience of explanation, this program checks all addresses 0 to 63 of the data table 22 every time the timer times up to confirm regular transmission, but other programs may also be used to do this. Needless to say. In addition, Fig. 15 a to c shows one timer means (setting time is 4 hours) for one wireless transmitter.
This figure shows the operation for determining abnormality in periodic transmission when the wireless transmitter A is provided in correspondence with the periodic transmission. Therefore, if reception is not confirmed within the set time 4h of the timer means, the timer means times out and generates a supervisor trouble alarm. 6000 → 6018 in Figure 16 is a specific usage example of Figure 15, in which a wireless transmitter in zone 6 for the purpose of monitoring fire sensors, etc. that requires high reliability has an individual timer means. This example shows an example in which a periodic transmission abnormality determination routine is incorporated into a warning mode program for a wireless transmitter in Zone 6. Unit codes 1 to 8 are assigned to each wireless transmitter in zone 6, and the corresponding 4-hour timer is assigned to each wireless transmitter in zone 6. We have UNIT(n)4H. 6011→6018 indicate subroutines that are executed by referring to the periodic transmission confirmation flag for each unit. In the system of the present invention having the above-mentioned functions, when setting the registration mode, the ID code of the wireless transmitter can be registered, and when in the warning 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. FIG. 17 shows the basic operation in the test mode, which is the main part of the system of the present invention.
After the registration mode ends, if you operate the test mode setting switch (shown as test switch 31 in the example in Figure 1a), the alarm LED that flashes when an alarm signal is received will flash to indicate that the test mode has been entered. is displayed (step 7001), and the ID code display 24 of the security information display means 24 is displayed.
In step a, the ID code of the registered wireless transmitter A is read into the display memory 37, and is sequentially scrolled and displayed at 2 second intervals by the display data readout control means 35 (7005→7009). When executing this program, it is sufficient to first read the data registered in the data table 22 into another display memory 37, and then read the data in this memory 37 when displaying. Then, when the wireless transmitter A is made to transmit a test signal and the received security signal is determined to be an alarm signal by the monitoring data determining means 34, the display data erasing means 36 is activated to erase the ID code. The security signal is sequentially erased from the display memory 37 and erased from the above-mentioned scroll display (7015→7021), but the received and decoded security signal is not an alarm signal due to a test operation, but is another abnormal signal (for example, a tamper signal, If it is a dead battery signal), the alarm is operated as is. In addition, a ninth system is provided with a condition memory 29 in the system.
In the case shown in FIG. 12, the abnormal data is further stored in the condition memory 29 together with the ID code (7015→7020). If you run the test mode in this way, the ID code of a normally working wireless transmitter will be:
The display of the ID code of the wireless transmitter that has been deleted from the scroll display and whose test operation has not yet been completed remains on the scroll display. In addition, regarding the wireless transmitter where an abnormality has occurred,
Since the ID code and abnormality data will be stored in the condition memory 29, it will be easier to deal with the occurrence of an abnormality, and to check the operation during testing, the wireless transmitter can be randomly operated on site. This has the advantage of making maintenance easier. 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, it is desirable that the main controller side be provided with a warning zone setting and a display means for displaying abnormalities in the warning zone. In the latter case, the abnormality may be displayed as long as it can be displayed in units of warning zones. FIG. 18 shows the external configuration of the main control MC, in which a warning switch 51 is used to set any of the warning zones 1 to 8 into operation.
~58, Warning indicator lamps 51a to 58a that display their setting status by lighting; warning lamps 5 that flash when an abnormality occurs in the zone that is on warning;
1b to 58b, an alarm 50, and a reset switch 59 for restoring the system. In addition, in order to execute a special alert mode to be described later, a home alert switch 61, an out-of-home alert switch 62, and corresponding operation display lamps 61a and 62a are provided, as well as a test mode setting switch to execute the test mode described above. 63 and its indicator lamp 63a. Note that in this example,
Since the receiver B is integrated into the main controller MC, an antenna 2a is provided. Fig. 19 is a circuit configuration diagram of a group of switches provided on the main controller MC side, and Fig. 20 is a circuit configuration diagram of its display section, and the same symbols as shown in Fig. 18 are given. The corresponding figures are shown below. When configuring such a system, receiver B
It is necessary to transmit the signals processed on the main controller MC side to the main controller MC side. Therefore, it is necessary to ensure that the data exchanged between the computer on the receiver B side and the computer on the main controller MC side is properly exchanged. be. 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 sensor to which device A is attached. As mentioned above, the wireless transmitter A of the present invention
There are some that detect the opening and closing of windows, etc., and send security signals when they are opened and closed.On the other hand, there are those that detect the heat rays of the human body and send the detection signal as a security signal only at the moment of detection. I have something to send. If such a signal is processed on the receiver B side, it can be treated as an abnormal signal, but when transmitting 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 F1 has an OFF output.
The two are distinguished by specifying the data without. 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 device configured to send an OFF signal when a window is closed, such as a window sensor. It means that the OFF signal does not come through. Security data with such a function code is transmitted from the receiver B side to the main controller.
As a result of the data being sent to the MC side, on the main controller MC side, for those without OFF output, after the security data is sent,
The alarm lamps 51a to 58a may be turned on for a certain period of time to display the alarm, and if there is an OFF output, the alarm lamp may be kept blinking until the OFF output is generated. 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, it activates the alarm, and at the same time transmits the security signal. Although the configuration is such that the ID code of the wireless transmitter that transmitted the message and the monitoring data are displayed on the display unit 24, such detailed information is not necessary in an actual system.
It may be possible to display whether an abnormality has occurred in any zone according to the operation of that sensor. Therefore, on the main controller MC side, alarm lamps (LEDs) 51b to 51b corresponding to each zone are installed.
58b is provided. Next, the necessary configuration for exchanging 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.

[Table] As shown in Table 1, the communication unit installed on the receiver B side constitutes a 4-byte data packet, and the second and third bytes are sent from the receiver B side to the main controller MC side. It constitutes a TEXT area that stores data. 2
The 3rd byte is a status byte for receiver B, in which the control signal from receiver B is stored together with the status, and the 3rd byte contains flags Z1 to Z8 indicating the warning zone where the abnormality occurred as a channel byte. Assigned and configured.
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 0 to 1, the main controller MC side can update the current message buffer that stores the message to be sent to the receiver B side, but until this flag changes from 0 to 1, , main controller
The MC side is required to continue sending the same message. Also, DEVICE is for storing the allocated address of receiver B, RFU is for unused area, and RFFAIL is for memory check.
When a trouble occurs in the memory on the receiver B side, the flag is set from 0 to 1. TAMPER, LOBAT, and SUPERV are status flags that indicate a tamper signal, a dead battery signal, and a regular transmission error, respectively. When an error occurs,
These flags are set. Further, 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 used as a communication unit to transfer data from the image controller MC side to the receiver B side.

[Table] As shown in Table 2, main controller MC
The communication unit provided on the side constitutes a 5-byte data packet, and the 2nd to 4th bytes constitute a TEXT area that stores the data sent from the main controller MC side to the receiver B side. The first byte is a control status byte for the controller MC, the third byte is a bypass setting byte, and the fourth byte is a 24-hour warning setting byte. The bypass setting for the 3rd byte and the 24-hour warning setting for the 4th byte are for each zone Z.
This is done by setting flags in the bits assigned to bits 1 to Z8. Also, the first byte is
Data 02 is stored in hexadecimal format, and the 5th byte is provided for a thumb check of the data in the 2nd and 2nd bytes. Here, NXTPMSG indicates that 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, the receiver B side can update the current message buffer that stores the message to be sent to the controller MC. 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 the test mode is set, and while this flag is set, other COMMAND bits are ignored.
TMPSTORE writes abnormal signals that occur only in warning zones that are not set to bypass or 24-hour warning to temporary memory (described later).While this flag is 1, bypass or 24-hour warning is set. Abnormal signals that occur only in warning zones that are not marked are written to temporary memory, but if this flag is set to 0,
During this period, the abnormal signal is not written to the temporary memory or condition memory. used in the system of the present invention
There are the types of COMMANDs shown in Table 3.

[Zone settings]

Any one of the warning zones 1 to 8 can be set to be in operation. Each zone is programmed to be on 24-hour alert throughout the day, but the following bypass setting is also possible in order to cancel the alert for a part of the zone.・Bypass alert settings Each zone can be set as bypass alert, which ignores the signal even when an abnormal signal is received, but when set to home, out, or individual alert, the predetermined zone becomes the bypass warning setting. In addition, in order to take appropriate precautions when you are at home or out, you can set the following precautions by operating the main controller MC's operation panel. 1 Home alert When you press the home alert switch 61, the home alert is activated.
The LED 61a lights up. While at home, residents constantly open and close indoor doors, so indoor security zones are set to bypass, but entrances, exits, and window zones are enabled and under security.
LED6La lights up. Also, in this case, from the main body,
"TMPSTORE" and "XFER" commands are set. To cancel the home alert, press the home alert switch 61 again. Then, the home alert LED 61a turns off, and the indoor alert zone bypass setting is canceled. In addition, the warning LEDs in the entrance/exit and window zones will also be turned off, and the "TMPSTORE" and "XFER" commands will also be reset. However, if the system alarm unit 50 issues an alarm, such a reset will not be possible. 2) Going out alert When you press the going out alert switch 62, the going out alert is activated.
LED62a lights up. In order to eliminate inconvenience when residents return from outside, indoor and exit warning zones are set to be bypassed for a certain period of time (for example, 15 seconds), and the bypass is canceled after that certain period of time. For this reason, the system of the present invention is provided with a temporary memory. Entrance and window zones are now alert and under alert.
The LED lights up and the alert LEDs in all zones light up. In this case, the command "TMPSTORE" is set from the main unit. If the reset switch 59 is not pressed within a certain period of time even when an abnormal signal other than the 24-hour alert or bypass alert zone is received during the outing alert,
"XFER" is set, and when the reset switch 59 is pressed, "CLRTEMP" is set. To cancel the going out alert, press the going out alert switch 62 again. Then, the going out warning LED 62a goes out, and the warning LEDs of all zones go out. "TMPSTORE" will also be reset. However, if the alarm unit 50 of the system issues an alarm, such a reset will not be possible. 3) Individual alert When you press alert switches 51 to 58 for each zone,
Warning LEDs 51a to 58 corresponding to what is pressed
a lights up, and bypass is set except for that zone. “TMPSTORE” and “XFER” are set from the main unit. When the warning switches 51 to 58 of each zone are pressed again, the warning LEDs 51a to 58a go out and the bypass setting is canceled. At this time, "TMPSTORE" and "XFER" are reset. However, if the alarm unit of the system issues an alarm, such a reset is no longer possible. Additions and deletions of alert zones are performed by pressing the alert switch for each zone, and input to the alert switch for zones that are set to be alerted 24 hours a day is not accepted. Furthermore, when the main controller MC receives an alarm from the receiver B, it operates as shown in Table 4.

[Canceling the alarm]

When the reset switch 59 is pressed once, "CLRTEMP" is set, which stops the alarm from sounding. Also, if you press the reset switch 59 again,
The LED will stop blinking and return to the state before the alarm. [Test Mode] When the test mode switch 63 is pressed, the LED 63a lights up during the test mode and "TSTMODE" is set. When the test mode switch 63 is pressed again, the LED 63a lights up during the test mode and "TSTMODE" is reset. [Operation when entering status] "RFFAIL", "TAMPER", "LOBAT",
When the status of “SUPERV” is input,
The buzzer beeps intermittently. When the reset switch 59 is pressed, the ringing stops. Note that the system is configured to give priority to a warning signal (alarm) over the status. Priority order of alert settings Boosting takes priority when setting alerts. Figure 21 shows the main control MC of receiver B.
FIG. Finally, the actual operation of the system of the present invention will be explained in the 22nd section.
Further explanation will be given with reference to the flowchart of the control processing shown in the figure. In this flowchart, a temporary memory is provided in order to be able to implement the out-of-home alert mode, and the security data received from wireless transmitter A is stored in its house code and ID.
After the codes are confirmed to match, they are temporarily stored in the temporary memory, and when the "CLRTEMP" command is received from the main controller MC side,
By clearing the data stored there, the security data is stored in the condition memory and the alarm is not activated. This temporary memory is used, as described above, when setting a warning to go out. There are also bypass settings and 24-hour alert settings, which can be set for each zone on the main controller MC side. In addition, in order to perform data transmission between the receiver B side and the main controller MC, a communication unit as described above is provided to handshake data between the two. , monitoring data is sent in the form of status, and information on the warning zone where an abnormality has occurred is provided for each warning zone, which is different from the ID code displayed on the receiver B side. It is structured as follows. Therefore, among the information registered or stored in the system data registration means 22, regarding the wireless transmitter A, OFF output and no tamper signal are sent to the main controller MC side along with information indicating the warning zone, and received. The monitoring data received and processed on the receiver B side is configured to be sent as a status according to its type, and on the other hand, the main controller MC sends information on the warning zone settings, bypass settings, and Various commands are to be sent. Note that in the figure, D and M indicate that no processing is performed. [Effects of the Invention] According to the system of the present invention, since it is configured to receive and process only security signals transmitted from registered wireless transmitters in the registration mode, the system can be divided into a plurality of security zones and Even when conducting a vigil, there is no risk of interference with security signals from wireless transmitters in other vigil zones. Additionally, when running the test mode, the ID codes of registered wireless transmitters are scrolled and displayed on the display, and the ID codes of wireless transmitters whose test operation has been confirmed are sequentially erased from the scroll display. It is extremely easy to check the operation of the test without leaving anything behind. Further, in the case where a periodic transmission abnormality determination means is provided, an abnormality in periodic transmission of a wireless transmitter having a periodic transmission function can be detected, so that the reliability of the unidirectional transmission system can be improved.
