本発明は、受信機からのアドレス指定による端末の順次
呼出しにより端末情報を受信して警報等を行う防災監視
装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disaster prevention monitoring device that receives terminal information by sequentially calling terminals by specifying an address from a receiver and issues a warning or the like.
［従来の技術］
従来の防災監視装置にあっては、受信機からのアドレス

致照合が得られると呼出しに続く応答タイミングで火災
検出情報を受信機に送信している。[Conventional technology] Conventional disaster prevention monitoring equipment uses a polling method that sequentially calls multiple terminals by specifying an address from a receiver, and when a terminal detects an abnormality such as a fire, the calling address is set to its own address. It waits until the address matches, and once the address matches, fire detection information is sent to the receiver at the response timing following the call.
ここで受信機から端末に対する呼出信号は電圧モード（
電圧パルス列信号）で送り、これに対し端末から受信機
に対する端末応答信号は電流モード（電流パルス列信号
）で送っている。Here, the calling signal from the receiver to the terminal is in voltage mode (
In contrast, the terminal response signal from the terminal to the receiver is sent in current mode (current pulse train signal).
更に、ポーリング方式では端末の異常検出から受信機で

を送信し、異常発生端末や異常の種別は不明であるが、
ともかく異常が発生したことを通知してプリアラームや
異常発生端末の検索を行わせることが考えられている。Furthermore, in the polling method, there is a large time delay between abnormality detection at the terminal and abnormality determination at the receiver, so when an abnormality is detected at the terminal, an interrupt pulse is sent from the terminal in current mode, and the abnormality occurs at the terminal. Although the type of abnormality is unknown,
In any case, it is being considered to notify that an abnormality has occurred and to perform a pre-alarm or search for the terminal where the abnormality has occurred.
この場合、異常の種別を示す割込レベルの異なる複数の

異常が同時に検出された場合には、異常の種別に応じた
割込レベルをもつ２つの割込パルスを順次送信すること
で、受信機は割込の発生原因を知って適切な対応策を取
ることができる。In this case, it is possible to transmit multiple interrupt pulses with different interrupt levels indicating the type of abnormality, and if different types of abnormalities are detected at the same time on different terminals, the interrupt pulses have an interrupt level according to the type of abnormality. By sending two interrupt pulses in sequence, the receiver can learn the cause of the interrupt and take appropriate countermeasures.
具体的には、割込レベル１〜３の３種類の割込パルスを
送信可能とした場合には、割込時間帯域を３つに分け、
各タイミングで割込パルスを電流モードで送信する。Specifically, when it is possible to transmit three types of interrupt pulses at interrupt levels 1 to 3, the interrupt time band is divided into three,
Send interrupt pulses in current mode at each timing.

識別が正確にできず、誤判断が多くなる問題があった。[Problems to be Solved by the Invention] However, when an interrupt pulse is transmitted by dividing the interrupt time band, terminals and receivers must The transmission and reception timings set in the system must be managed very strictly. Furthermore, due to the transmission characteristics, the received waveform of the interrupt pulse may have waveform distortion or phase lag, and attempting to compensate for this cause of deterioration will complicate the circuit configuration, and if compensation is not done, the interrupt pulse cannot be identified accurately. There was a problem with many misjudgments.

きる。[Function] According to the disaster prevention monitoring device of the present invention having such a configuration, different interrupt levels can be set depending on the fire detection of the fire transmitter, the fire detection of the fire detector, the pre-alarm level of the analog sensor, etc. The transmission and reception time timings of interrupt pulses corresponding to each interrupt level are assigned sequentially within the interrupt transmission and reception band with a free time in between, making it possible to transmit two types of interrupt pulses at the same time. Even if the two interrupt pulses are executed, there is a free time between the two interrupt pulses, so even if there is a shift (phase shift) on the time axis due to transmission characteristics or timing deviation, there will be no mutual interference. It is possible to accurately identify each interrupt pulse and perform appropriate reception processing according to the interrupt level without strict transmission degradation compensation or timing management.

Furthermore, regarding the interrupt level 3 indicating the pre-alarm level, fire determination processing based on detection data from the analog sensor in the control unit 32 is activated.

ことから割込レベル１を認識することができる。FIG. 7 is a timing chart when a fire is detected at the terminal 12-n. When a fire is detected at the terminal 12-n, an interrupt pulse is transmitted using the interrupt transmission band TSn at the terminal 12-n after the fire is detected. At this time, assuming that a fire detection output from the fire transmitter is obtained at the terminal 12-n, an interrupt pulse is sent to the receiver 10 at the timing of interrupt level 1 in FIG. Terminal 12-
The interrupt pulse from n is received in the corresponding interrupt reception band TR of the receiver 10, and since the reception timing is bit b1, the interrupt level 1 can be recognized.

Since there is a free time between each interrupt pulse when sending them sequentially, even if there is a shift in the transmission timing of the interrupt pulse due to variations between terminals or a phase shift due to transmission characteristics,
It is possible to accurately detect interrupt pulses and pulse timing on the receiver side without causing interference between adjacent interrupt pulses, and to take appropriate countermeasures on the receiver side based on the interrupt level.
