るテレメータ系の観測呼出に関するものである。Detailed Description of the Invention The present invention comprises a telemeter monitoring station (hereinafter referred to as a monitoring station) and a large number of at least two or more telemeter observation stations (hereinafter referred to as an observation station). This relates to observation calls for telemetry systems connected to stations via simplex radio lines.
従来この種の系における観測呼出は、単信無線
回線により次の中のいずれか１つによつていた。 Traditionally, observation calls in this type of system have been made over simplex radio lines using one of the following methods:
(1) 個別呼出方式
(2) 群別呼出方式

ている。(1) Individual calling method (2) Group calling method In method (1), each observation station is assigned a unique station calling signal, and each observation station can be monitored manually or automatically whenever data is required. Each station sends out a call signal, and the observation station transmits data to the monitoring station only when it is selected.

べて、データの収集時間が長いことである。 The feature of this method is that data from any one observation station can be collected at any time. On the other hand, the disadvantage of this method is that since it is necessary to send out a paging signal for each station, the data collection time is longer than that of the second method described later.

なる。 The feature of this method is that all the calling signals are sent together into one
Since it only needs to be sent twice, the data collection time is shorter than in method (1). On the other hand, the drawback is that if data cannot be collected from even one station among the n observation stations, all stations will be called again, and the data collection time will be longer than when calling one station again. Become. (Re-calling refers to calling again) Furthermore, even if it is desired to collect data for only one station, all stations will be called as a result, and the data collection time will be longer than when calling only one station.

に説明する。 The present invention solves the drawbacks of both methods (1) and (2).In a telemetry system in which one monitoring station and at least two observation stations are connected by a simplex radio line, all stations The first call is made by group, which shortens the data collection time, and in the case of missing data, when calling again, only the missed stations are individually called again. The purpose of this method is to shorten the data collection time as much as possible, and will be described in detail below with reference to the drawings.

置５を介して送信される。 Next, the operation will be explained in the order in which individual calls are added to group calls. Here, when the monitoring station 1 issues a command to transmit data to a group of observation stations by group calling, one observation station in the specified observation station group is designated as the observation station 6. Note that one observation station group is composed of a plurality of observation stations. First, although not shown in the figure, when the monitoring station 1 calls the setting of a specific group using a switch or the like, the group designation signal from the group call control circuit 2 is modulated by the modulation/demodulation circuit 4 and transmitted via the transmitting/receiving device 5. be done.

う。 On the other hand, in the designated group, each observation station simultaneously receives this group designation signal, and for example, observation station 6 operates as follows. The transmitted signal is received by the transmitting/receiving device 6 and demodulated by the modulation/demodulation circuit 8 . This demodulated signal is sent to the group reception control circuit 11, where it is determined whether or not the group designation signal has a specified length, and if it has the specified length, the data is sent after a certain delay time has elapsed. Therefore, the timer 10 is operated. Here, this timer operation time is used to enable each observation station to transmit data after a pre-assigned unique delay time has elapsed. Therefore, after the operation delay time of the timer 10 has elapsed, the transmission control circuit 7 is operated for the necessary time, and the data is modulated by the modulation/demodulation circuit 8 and transmitted to the monitoring station 1 via the transmission/reception device 9. Note that each observation station performs this transmission operation in sequence.

述と同様の動作をくり返していた。 In the monitoring station 1, data from each observation station is sequentially received via a transmitter/receiver 5 and demodulated by a modulation/demodulation circuit 4. Furthermore, this demodulated data is sent to a reception control circuit 4', where it is determined whether or not there is any data missing from each observation station. In this case, in the conventional system, if there is even one station with data missing, the same operation as described above is repeated for all observation stations so that data is transmitted again to all observation stations.

すべての動作を終了する。 However, in the case of the present invention, individual calls are made only to observation stations for which data is missing, and this will be described below. First, the reception control circuit 4' of the monitoring station 1
When determining the observation station with missing data in the received data,
The individual call control circuit 3 operates, and the individual call signal for the observation station is modulated by the modulation/demodulation circuit 4 and transmitted via the transmitting/receiving device. On the other hand, the observation station 6 that has received the individual designation receives this designation signal via the transmitting/receiving device 9 and demodulates it in the modulation/demodulation circuit 8 . Furthermore, this demodulated signal is sent to the individual control circuit 12, which controls the transmission control circuit 7 and transmits the data to the modulation/demodulation circuit 8.
and transmit via the transmitting/receiving device 9. Monitoring station 1
Now, this data is received in the same manner as described above, and the entire series of operations is completed.

c and d show response data signals from the observation station, and in particular, c shows the case where the A2 station is called again and the data is returned again because there is a drop in the data from the A2 station.

This shows the case where all stations in the group are called again.

にデータの収集時間の短縮について述べる。 Furthermore, FIG. 4 is a time chart for the case according to the present invention, in which the G1 group is first called, and here,
A case is shown in which a call is made to only A2 station again because there is a loss in A2 station. Note that t 1 is the paging signal time, t 2 is the individual paging data return time, and t 3 is the group-specific paging data return time, approximately t 2 ≈t 3.Next , the shortening of the data collection time will be described.

短である。 The data collection time is 4 (t 1 + t 3 ) in the individual calling method shown in Figure 2, and 2 (t 1 + t 3 ) in the group calling method shown in Figure 3.
3t 3 ), and 2t 1 + in the calling method according to the present invention shown in FIG.
3t 3 +t 2 . For example, when the telemeter standard method is applied, t 1 ≒ 2.5 seconds, t 2 ≒ t 3 ≒ 5 seconds, and the data collection time is 30 seconds in Figure 2, 35 seconds in Figure 3,
FIG. 4 = 25 seconds, and the calling method according to the present invention is the shortest.
一般に観測局数がｎ、データ欠測局数がｍの場
合データ収集時間Ａ，Ｂ，Ｃは、下記のとおりと
なる。 Generally, when the number of observation stations is n and the number of stations with missing data is m, the data collection times A, B, and C are as follows.
（観測局群別数＝１とする。）
個別呼出方式Ａ＝ｎ（t1＋t2）＋ｍ（t1＋t2）
＝（ｎ＋ｍ）（t1＋t2）
群別呼出方式Ｂ＝２（t1＋nt3）
本発明による呼出方式Ｃ＝t1＋nt3＋ｍ（t1＋t2）
ここでＡ，Ｂ，Ｃの大小について比較してみる
とt2≒t3の為、Ａ−Ｃ＝nt1＋nt2−（t1＋nt3）＝（ｎ
−１）t1
ここでｎ≧２の為、Ａ−Ｃ＞０ ∴Ａ＞Ｃであ
る。(The number of observation stations by group = 1.) Individual calling method A = n (t 1 + t 2 ) + m (t 1 + t 2 ) = (n + m) (t 1 + t 2 ) Group calling method B = 2 (t 1 + nt 3 ) Calling method according to the present invention C = t 1 + nt 3 + m (t 1 + t 2 ) Here, when comparing the sizes of A, B, and C, t 2 ≒ t 3 , so A - C = nt 1 + nt 2 - (t 1 + nt 3 ) = (n
-1) t 1 Here, since n≧2, A−C>0 ∴A>C.
同様にして Ｂ−Ｃ＝t1＋nt3−ｍ（t1＋t2）
ここで t2≒t3の為、t1／t2＝ｒとすればt1＝rt2
∴Ｂ−Ｃ＝rt2＋nt2−ｍ（ｒ＋１）t2
＝t2｛ｒ＋ｎ−ｍ（ｒ＋１）｝
ここでｒ＋ｎ−ｍ（ｒ＋１）＞０ならＢ＞Ｃとな
る。 Similarly, B-C=t 1 +nt 3 -m(t 1 +t 2 ) Here, since t 2 ≒ t 3 , if t 1 /t 2 = r, then t 1 = rt 2 ∴B-C=rt 2 +nt 2 -m(r+1)t 2 =t 2 {r+nm(r+1)} Here, if r+nm(r+1)>0, B>C.
すなわちｍ＜ｒ＋ｎ／ｒ＋１ならＢ＞Ｃとなる。 That is, if m<r+n/r+1, then B>C.
仮にｒ＝0.5とすれば、ｍ＜２／３（ｎ＋１／２なら ば、Ｂ＞Ｃとなる。 If r=0.5, m<2/3 (n+1/2 then For example, B>C.
同様に、ｒ＝１とすれば、ｍ＜１／２（ｎ＋１） ならば、Ｂ＞Ｃとなる。 Similarly, if r=1, m<1/2(n+1) Then, B>C.
同様に、ｒ＝２とすれば、ｍ＜１／３（ｎ＋２） ならば、Ｂ＜Ｃとなる。 Similarly, if r=2, m<1/3(n+2) Then, B<C.
同様に、ｒ＝３とすれば、ｍ＜１／４（ｎ＋３） ならば、Ｂ＜Ｃとなる。 Similarly, if r=3, m<1/4(n+3) Then, B<C.
例えばテレメータ標準方式を適用した場合 t1≒2.5秒、t2≒５秒となる為、ｒ≒0.5となり ｍ＜２／３（ｎ＋１／２）ならば、Ｂ＞Ｃとなる。 For example, when the telemeter standard method is applied, t 1 ≒2.5 seconds and t 2 ≒5 seconds, so if r≈0.5 and m<2/3 (n+1/2), then B>C.
従つて前記の様に、個別呼出方式のデータ収集
時間Ａと本発明による呼出方式のデータ収集時間
Ｃは、ｎ≧２で、Ｃ＜Ａとなり、本発明による呼
出方式が有利となる。 Therefore, as described above, the data collection time A of the individual paging method and the data collection time C of the paging method according to the present invention are n≧2, C<A, and the paging method according to the present invention is advantageous.
同様に、群別呼出方式のデータ収集時間Ｂと、
本発明による呼出方式のデータ収集時間Ｃは、ｍ
＜ｒ＋ｎ／ｒ＋１でＣ＜Ｂとなり、本発明による呼出方
式が有利となる。 Similarly, the data collection time B of the group calling method,
The data collection time C of the paging method according to the present invention is m
<r+n/r+1, C<B, and the calling method according to the present invention is advantageous.
以上説明したように、本方式は通常は群別呼出
方式にてデータ収集時間を最短にし、データの同
時性を確保し、データ欠測の場合は、その局のみ
個別呼出することによつてデータ収集時間をでき
るだけ最短にしようとするもので、データ量の多
いシステムに最適である。 As explained above, this method usually minimizes data collection time by calling by group, ensuring data simultaneity, and in the case of missing data, calls only that station individually. It aims to minimize the collection time as much as possible, and is ideal for systems with a large amount of data.
