Abstract

PROBLEM TO BE SOLVED: To provide the remote information system device which is more superior in reliability by making a transmitter, which sends out a periodic diagnostic signal for operation confirmation periodically and also sends transmitted information out each time the transmitted information is generated, quit sending the periodic diagnostic signal out after the transmitted information is sent out. SOLUTION: A patient in, for example, medical facilities carries a transmitter 1, which sends out the periodic diagnostic signal Po for operation confirmation periodically. If the patient feels ill and presses a push-button switch S, the transmitter sends security alarm information Pa out as a radio wave. The transmitter 1 once sending the security alarm information Pa operates a periodic diagnostic signal interruption program as a periodic diagnostic signal interrupting means to stop sending the periodic diagnostic signal Po out. Therefore, even if a receiver pertermits the sent information Pa for some reason and generates no alarm, the stop of the periodic diagnostic signal Po is not pertermitted, so that the remote information system which is improved in reliability is obtained.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote reporting system device for reporting various information such as fire, crime prevention, poor physical condition, etc. via a wireless or telephone line.

[0002]

2. Description of the Related Art In a remote notification system device, for example, a transmitter for transmitting various information such as fire, crime prevention, and physical condition, and a transmitter installed in a predetermined management center for waiting information transmitted by the transmitter. Consists of a receiver to receive,
There is a system device in which the transmitter sends information only when needed, but does not send any information at other times.

As for the scale of the remote notification system device, the transmitter is various sensors transferred from the building monitoring device that centrally monitors various security sensors such as fire sensors and crime prevention sensors existing in the entire building. The alert information is attached with a transmitter identification code (address) to form security alert information, and the security alert information is sent out as a wireless signal or a wired signal. From a large-scale system installed in a control center, etc., the transmitter is integrated with a sensor, an emergency push button switch, etc. so that each individual can carry it, and the sensor issues a warning or the emergency push button switch is pressed. In this case, the transmitter identification code (address) is added and the security alert information is transmitted as a wireless signal, and the receiver is, for example, a management office in a medical facility. Present up to small-scale systems such as those installed in.

By the way, in the remote notification system device, due to some trouble such as a transmitter or a receiver, a communication line or a radio wave propagation state, the information which should be received by the receiver and notified should not be notified. There may be cases where you are lost. In such a case, in the remote notification system device used as the security system as described above, the missed notification becomes a serious problem, so the system operation check is periodically performed from the transmitter at an appropriately set time interval. While sending out a regular diagnostic signal for
By making the receiver receive the periodical diagnostic signal, avoiding a situation in which the remote notification system device does not realize the original function for a long period of time, and preventing a serious misreporting. ing.

FIG. 4 is a timing chart for explaining the timing of transmitting the regular diagnostic signal of the conventional remote notification system device. FIG. 4 (a) shows the transmission timing in the normal state, and FIG. 4 (b) shows the security. It shows the transmission timing when the notification information is transmitted.

The transmitter of the remote reporting system device is

[0007] On the other hand, the receiver normally adds a reception time based on its own timer IC to a message indicating that the regular diagnostic signal P ₀ is received every time it receives the regular diagnostic signal P _0. While performing printing and recording with the printer, starting from the reception completion time of the periodic diagnostic signal P ₀ as the starting point, the time measurement is started from the beginning based on the timer IC provided in the printer until the time measurement time reaches the time interval T. Whether or not the regular diagnostic signal P ₀ is received from the transmitter is monitored, and if the regular diagnostic signal P ₀ is not received within the time interval T, it is determined that the system is abnormal, and the system abnormality is printed by the printer and the speaker. The alarm is sounded by.

Further, the receiver is provided with the security alert information P
_{When a} is received, an alarm sound is emitted by the speaker, and at the same time, the message indicating that the security alert information P _a is received is printed and recorded by the printer with the reception time based on its own timer IC. I do. In addition, the receiver 2 starts the time measurement from the beginning based on the timer IC included in the receiver 2 from the completion time of the reception of the security alert information P _a , and the transmitter 2 transmits the time until the time interval reaches the time interval T. Whether or not the periodic diagnostic signal P ₀ is received from the system is monitored, and if the periodic diagnostic signal P ₀ is not received within the time interval T, it is considered that the system is abnormal and the system abnormality is printed by the printer and the alarm is issued by the speaker. It is notified by the sounding of the sound.

However, a slight error occurs in each of the timer ICs provided in the transmitter and the receiver of the remote notification system device, and the timing at which the time interval T is reset and restarted is also received by the transmitter and the receiver. It differs slightly depending on the machine.

Therefore, in order to prevent the remote notification system device from being erroneously recognized as having a system abnormality due to an error in the timer IC or a difference in the timing of restart, it has been conventionally performed. In the remote notification system device of No. 2, if the receiver does not receive the regular diagnostic signal P ₀ exactly by the time interval T, the receiver does not judge that the system abnormality has occurred and notifies the system abnormality, for example, 2 minutes. The system abnormality is determined based on the margin time α.

Therefore, as is apparent from the above description, in the case of the conventional remote notification system device, the receiver should overlook (miss) the security alert information P _a. also, the transmitter that sent the security alarm information P _a resets the counted time ever when it has finished sending a security alarm information P _a, and starts measuring the first interval counted time is the time When T is reached, the regular diagnostic signal P ₀ is sent out, so that FIG.
If the time interval T _a shown in is longer than the margin time α described above, the receiver monitoring the presence / absence of the periodic diagnostic signal P ₀ from the transmitter can notify the system abnormality, and It is possible to provide a fine-grained service by operating the remote notification system device in consideration of the fact that the notification of the system abnormality by the above includes the one due to the above-mentioned false alarm.

[0012]

However, in the conventional remote notification system device, the security notification information P _a is lost and the security notification information P _a is lost.
_If the time interval T _a between the _a and the immediately preceding periodic diagnostic signal P ₀ is shorter than the above-mentioned margin time α, the receiver does not notify the security alert information P _a or the system abnormality. As a remote notification system device for security, there was a problem in that there was some concern about the reliability.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a remote notification system device which is further excellent in reliability.

[0014]

In order to solve the above problems, the present invention transmits a periodic diagnostic signal for operation confirmation on a regular basis, and transmits the transmission information each time the transmission information is generated. In a remote notification system device including a transmitter and a receiver that waits for and receives transmission information transmitted by the transmitter, the transmitter stops transmission of the periodic diagnostic signal after transmitting the transmission information. It is characterized by comprising means.

The security alert information P _a indicating the corresponding physical condition is modulated and output to the wireless transmission unit 13. The wireless transmission unit 13 power-amplifies the modulation signal output from the modulation unit 12, and radiates it as a radio wave into space from the antenna A ₁ .

The notifying section 14 is a section for notifying a message by voice or display based on an instruction from the transmission control section 11, and is composed of a speaker and a liquid crystal display section. The storage unit 15 stops the transmission of the regular diagnostic signal P ₀ after transmitting the security alert information P _a , stores the regular diagnostic signal suspension program corresponding to the regular diagnostic signal suspension means, and transmits the transmitter identification code ( This is a part for storing data such as addresses. The battery power source E ₁ is a power source that drives the transmitter 1.

The receiver 2 is installed on, for example, a desk of an office in a medical facility, and as shown in FIG.
A wireless reception unit 20, a demodulation unit 21, a reception control unit 22,
The notification unit 23, the operation input unit 24, the storage unit 25, and the power supply unit E ₂ are provided. The wireless receiver 20 has an antenna A.
_The radio wave received by ₂ is amplified and output to the demodulation unit 21. The demodulation unit 21 demodulates the modulated signal and performs waveform shaping, and outputs the periodic diagnostic signal P ₀ and the security alert information P _a , which are digital signals, to the reception control unit 22. The reception control unit 22 controls the entire receiver 2 and includes a microcomputer and a timer IC. The notification unit 23 is a unit that notifies a message by voice or display based on an instruction from the reception control unit 22, and includes a speaker, a liquid crystal display unit, a printer, and the like.

The operation input section 24 is a section for switching the receiver 2 between a registration mode, a normal mode and a deletion mode. The receiver 2 in the registration mode can store the transmitter identification code (address) to be received by the receiver 2 in the plurality of transmitters 1 in the storage unit 25.
Further, when the receiver 2 in the normal mode waits for the radio wave and receives the periodic diagnostic signal P ₀ and the security alert information P _a including the transmitter identification code (address) registered as the reception target, The notification unit 23 notifies that effect. Further, the receiver 2 in the erase mode can erase any transmitter identification code (address) stored in the storage unit 25.

The power source unit E ₂ is a power source that drives the receiver 2, and supplies power by rectifying a commercial power source.

The remote notification system device including the transmitter 1 and the receiver 2 as described above operates as follows and is operated as follows. That is, for example, a patient in a medical facility always wears the transmitter 1. The receiver 2 is installed on the desk of the office in the medical facility, and stores the transmitter identification code (address) of the transmitter 1 owned by each patient in the medical facility in the storage unit 25. are doing. Further, the reception service area of the receiver 2 is limited to the building of the medical facility. The transmitter 1 carried by the patient transmits the periodic diagnostic signal P ₀ from the antenna A ₁ as a radio wave every time a predetermined time interval T elapses. The periodic diagnostic signal P ₀ as a radio wave is received by the antenna A ₂ of the receiver 2 and recognized by the reception control unit 22 of the receiver 2.

The reception control unit 22 confirms that the transmitter identification code that includes a periodic diagnosis signal P ₀ thus received (address) is a periodic diagnosis signal P ₀ from the transmitter 1 to be received,
If the periodic diagnostic signal P ₀ from the transmitter 1 to be received is
The time when the reception of the periodic diagnostic signal P ₀ is completed is indicated by the timer IC.
(Not shown), the time when the reception of the regular diagnostic signal P ₀ is completed is stored in a time data table (not shown) corresponding to the transmitter identification code (address), and the regular diagnostic signal P ₀ is stored. _The “time” at which the reception of ₀ is completed, the message “periodical diagnostic signal reception”, and the “transmitter identification code (address)” are output to the printer of the notification unit 23.

Thereafter, the reception control unit 22 compares, for example, every 10 seconds, each previous reception completion time stored in the clock data table with the current time engraved by the timer IC (not shown). Latest periodic diagnostic signal P ₀
Alternatively, it is confirmed whether or not the elapsed time from the reception of the security alert information P _a to the present exceeds the time obtained by adding the margin time α to the predetermined time interval T. If there is something that exceeds the time interval T + α, the reception control unit 22 sounds an alarm sound from the speaker of the notification unit 23, and the message “current time”, “periodic diagnostic signal interruption”, and “transmitter”. The identification code (address) "is output to the liquid crystal display unit of the notification unit 23 and the printer.

By the way, when a patient carrying the transmitter 1 feels sick and presses the push button switch S, the transmitter 1 sends out the security alert information P _a as a radio wave. Once the transmitter 1 has sent out the security alert information P _a , the transmitter 1 thereafter activates the regular diagnostic signal suspension program corresponding to the regular diagnostic signal suspension means, and as shown in the timing chart of FIG. Stop sending ₀ .

Security alert information P as radio waves
_{The a} is received by the antenna A ₂ of the receiver 2 and recognized by the reception control unit 22 of the receiver 2. Reception control unit 22 confirms that the transmitter identification code that includes a security alarm information P _a thus received (address) is a security alarm information P _a from the transmitter 1 to be received, the transmission of the reception target Machine 1
If the security alert information P _a is from the timer IC, the time when the reception of the security alert information P _a is completed is determined by the timer IC.
(Not shown), the security alert information P
_The time at which the reception of a is completed is stored in the clock data table (not shown) corresponding to the transmitter identification code (address). At the same time, the reception control unit 22 causes the speaker of the notification unit 23 to sound an alarm sound, and also displays the “time” at which the reception of the security notification information P _a is completed, the message “reception of security notification information”, and the “transmission”. The machine identification code (address) "is output to the liquid crystal display unit of the notification unit 23 and the printer.

Thereafter, the reception control unit 22 compares, for example, every 10 seconds, each previous reception completion time stored in the clock data table with the current time engraved by the timer IC (not shown). Latest periodic diagnostic signal P ₀
Alternatively, it is confirmed whether or not the elapsed time from the reception of the security alert information P _a to the present exceeds the time obtained by adding the margin time α to the predetermined time interval T.

By the way, the transmitter 1 which has transmitted the security alert information P _a by the operation of the patient has stopped the transmission of the regular diagnostic signal P ₀ . Therefore, the receiver 2
To the transmitter 1 that has sent out the security alert information P _a , this time, an alarm sound is emitted from the speaker of the notification unit 23, and a message “current time” and “discontinuation of the periodic diagnostic signal” are displayed. The transmitter identification code (address) "is output to the liquid crystal display unit of the notification unit 23 and the printer.

That is, in the remote notification system device of the above-mentioned embodiment, normally, the alarm is issued twice, that is, the alarm by the security alert information P _a and the alarm by the interruption of the regular diagnostic signal P _0. There is always an opportunity to inform. Therefore, in the conventional remote reporting system apparatus, with such propagation conditions of radio waves loss report the reception of poor security alarm information P _a, security alarm information P _a periodic diagnosis signal P ₀ poor timing of the delivery delay However, in the remote notification system device of the above-described embodiment, the security alert information P _a may be overlooked.
Even if the reception of the alarm is lost, an alarm due to the interruption of the regular diagnostic signal P ₀ is always output, and the redundancy is established, so that the reliability can be improved.

The present invention is not limited to the above-described embodiment, the transmitter may be installed rather than being carried, and the push button switch S may be a crime prevention sensor or a fire sensor. May be Further, it goes without saying that the communication between the transmitter and the receiver may be a wired line as well as a wireless line.

[0032]

According to the present invention, since the transmitter stops transmitting the periodical diagnostic signal after transmitting the transmission information, the receiver should overlook the transmission information for some reason and give a false alarm. Even if it happens, even if the stop of the periodical diagnostic signal is not overlooked and the alarm is not lost, it is possible to provide a remote reporting system device with improved reliability by providing reliable redundancy.
