2, ..., m) are observation points, S _{i, j} (i = 1,2, ..., n;
j = 1, 2,..., m) is the observation range for the observation point V _{i, j} .

That is, the control command information given from the steady control command storage unit 10 to the drive mechanism control unit 21 is stored in the information storage unit 24.
The observation range S _{i, j} (i = 1, 2,..., N; j =
To obtain the information of 1, 2, ..., m), the observation point V

The specific control command information includes the position of the drive and secrecy with respect to the observed mechanism unit 22, the sensitivity and the magnification of the observation information input unit 23, and the collected information obtained is the sensitivity and the magnification of the observation information input unit 23 and the measurement position thereof. And so on.

[0007] The operation of the remote observation system starts with obtaining information of an observation object at the observed device 2. First, after fixing the observation object to the observed mechanism section 22, the fixed control instruction storage section 25
Start The activated standard control command storage unit 25 stores a predetermined control command based on control command information stored in advance,
Drive mechanism control unit 21, information storage unit 24, and communication control unit 2
Transfer to 6.

The first control command is an initialization command and the like, which initializes each section, and initializes the drive mechanism control section 21 and the information storage section 24 with respect to the observed mechanism section 22 and the observation information input section 23, respectively. Perform parameter or electrophysical initial input.

Upon completion of the above, the fixed control command storage unit 25 sends preset command information to the drive mechanism control unit 21 and receives the command information.
Reference numeral 1 denotes a mechanism for driving the observed mechanism unit 22 by converting the observed mechanism unit 22 into a format in which the observed mechanism unit 22 can operate, for example, converting numerical data into a voltage or current level, or performing a conversion process into a command level execution format. And observation information input unit 2
3 is automatically stored in the information storage unit 24.

The completion of information storage in the information storage unit 24 is notified to the standard control instruction storage unit 25. Upon receiving the notification, the fixed control command storage unit 25 sends the observation device 1 _k (k = 1, 2,...) To which the preset accumulated observation information is to be sent.
l) are individually called one by one via the communication network C, and the collected observation information is transmitted to the observation device 1 _k (k = 1,
2, ..., l).

The transferred observation information is transmitted to the observation device 1
_{At the same time as} the information is stored in the information storage unit 14 of _k (k = 1, 2,..., l), this arrival notification is sent to the observation device 1 k (k = 1, 2).
The observer is notified via the monitoring unit 11 of (2,..., L).

The observer receiving the notification (here, an observer handling the observation device 1 _k ) receives a mouse or a mouse provided in the monitoring unit 11 of the observation device 1 _k in response to the control command unit 12. The information stored in the information storage unit 14 is displayed on the monitoring unit 11 using input means such as a keyboard, and the observation target is observed, and an appropriate comment or the like is created.

Further, if the information is insufficient, the observer, the necessary control command by using the input means such as a mouse or a keyboard provided in the monitoring unit 11 of the observation device 1 _k to the control instruction unit 12 Is created and transmitted to the communication control unit 26 of the observed device 2. Specifically, the observation device 1 _k
A control command is transmitted to the communication control unit 26 of the observation target device 2 connected to the observation device 1 _k via the communication network C by using a communication path set in advance or newly setting a communication path. I do.

The communication control unit 26 of the device under observation 2 that has received the control command transmits the received control command to the information storage unit 2.
It is determined whether or not the received data is a data transfer instruction from the control unit 4. If the received data is not a data transfer instruction, the fixed control instruction storage unit 25 is notified that there is received data (a control instruction has been received). In the case of a command, the reception data exists in the information storage unit 24 (control command has been received).
Notify.

The notified information storage unit 24 retrieves the designated portion from the collected and stored observation information based on the received data, and specifically, searches for the designated portion of the designated information. The range is specified, the information on the memory recorded in this area is copied, and this information is transmitted to the communication control unit 26. Thus, the information transmitted to the communication control unit 26 is transmitted to the monitoring unit 11 of the observation device 1 _k via the individual communication network C.

The above operation is repeated, so that required observation information can be finally independently presented for each observer.

[0017]

A problem with the conventional remote observation system described above is that a single unit exists between the observed device 2 and the observation device 1 _k (k = 1, 2,..., L). For example, the observation point V _{i, j} (i = 1,
, N; j = 1, 2,..., M) and the corresponding observation range S _{i, j} (i = 1, 2,..., N; j = 1, 2,.
m) is replaced by all or necessary observation devices 1 _k (k = 1, 2, 2)
.., L), they had to be transmitted sequentially.

For this reason, when the information amount of one communication unit is large and the number of the observation devices 1 _k (k = 1, 2,..., L) is large, the observation information accumulated from the observed device 2 is stored. Observation device 1 _k (k = 1, k = l,
2, ..., l) and the observation device 1 _k (k = 1,2, ...,
In 1), a considerable amount of time is spent until the observer starts observation, and a plurality of observation devices 1 _k (k = 1,
2,..., L) are factors that alienate the speeding up of rapid observation.

To solve this problem, the broadcast service of the communication network C can be used, but it is necessary to determine a broadcast transmission destination in advance. Further, after the end of the broadcast communication, the communication control unit 26 can perform individual communication such as general data communication service in preparation for individual communication from the observation device 1 _k (k = 1, 2,..., L). It is necessary to change to the state,
There is a problem in operability of the observed device 2 and simplification of the communication procedure.

A broadcast using satellite communication or the like can be used, but this means that it is possible to eavesdrop on terminals other than an unspecified number of remote observation systems. In this case, a robust encryption means is used. In order to prevent falsification, it is necessary to apply an authentication means, and there is a problem not only in system operability but also in cost increase.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a high-speed encryption and authentication process of transmitted information and to a required observation device without using hardware or software such as a dedicated board for performing the process. Another object of the present invention is to provide a remote observation system that can transmit the same information to a user, and can speed up the start of observation and reduce the system operation cost.

[0022]

According to the present invention, in order to achieve the above object, according to the present invention, there is provided an apparatus to be observed installed on the observation object side, and at least one observation apparatus installed on the observation side. A remote observation system configured to communicate between a device to be observed and an observation device using a broadcast communication network and an individual communication network to observe an observation target in a remote place. Is an information collection and accumulation unit that subdivides and collects the observation information of the observation target object and accumulates the information as a plurality of subdivision information, and a random number permutation of the plurality of subdivision information stored in the information collection and accumulation unit. Information group generating means for generating the rearranged observation information group and restoration information for returning the permutation of the segmented information constituting the observation information group to the permutation before the rearrangement; and transmitting the observation information group to the broadcast type. Send to each observation device using communication network Communication means for transmitting the restoration information to each observation device using the individual communication network, and performing individual communication with each observation device using the individual communication network. Receives the observation information group transmitted through the broadcast communication network and the restoration information transmitted through the individual communication network, and performs individual communication with the observed device using the individual communication network. Communication means, based on the restoration information received by the communication means,
Information acquiring means for assembling the permutation of the segmented information constituting the observation information group received corresponding to the restoration information by returning the permutation to the permutation before the rearrangement; and monitoring for presenting the information assembled by the information acquiring means to the observer. And a remote observation system comprising means.

According to the remote observation system, in data communication between the observed device and the observation device, when the subdivided information stored in the information collecting and storing means of the observed device is transmitted to the observation device, Generates a group of observation information obtained by randomizing subdivision information and restoration information that can be restored based on it. The observation information group uses a broadcast-type communication network. Individual communication with the device is performed using an individual communication network different from the broadcast communication network, and the observation device restores the observation information based on the restoration information and presents it to the observer by the monitoring means.

[0024] Thereby, since the permutation of the plurality of segmented information constituting the observation information group is rearranged in a random manner, complete observation information can be obtained even if only the observation information group is acquired. Instead, complete observation information can be obtained from the observation information only by the observation device that has acquired the restoration information. That is, in communication between the observed device and the observation device, information requiring broadcast and synchronization are separated into pieces of information that are separately arranged and restoration information that restores the arrangement of the pieces of separated information to the original state. By transmitting the restoration information through a separate data communication network and restoring the observation information obtained from the observed device via the broadcast communication network with the restoration information, the broadcasting and simultaneity to the observation device can be improved. To secure observation, shorten the transmission time and equalize the data communication band, and to prevent the leakage of observation information by transmitting the restoration information using the individual communication network, so that the observation can be started in a short time. An inexpensive and highly efficient remote observation system can be realized.

According to a second aspect of the present invention, in the remote observation system according to the first aspect, the information collecting and accumulating means subdivides the observation target into a plurality of observation ranges based on the subdivision parameters. Observing the observation target object, collecting the subdivision information, storing the subdivision parameters and the subdivision information in association with each observation range, and the information group generating means forms the permutation of the rearranged subdivision information. We propose a remote observation system that uses the subdivision parameters whose permutations are rearranged to correspond to the reconstruction information.

According to the remote observation system, for example, subdivision information is collected for each of a plurality of observation regions subdivided based on subdivision parameters representing the positions of observation points, and the subdivision parameters and the subdivision information are collected. The observation information group and the restoration information are generated by rearranging the permutations equally in a random manner in a state where the observation information group is associated with each observation range. Therefore, even if only the observation information group is obtained, complete observation information cannot be obtained, and assembling of the subdivision information constituting the observation information group only by the observation device that has obtained the restoration information and obtained the subdivision parameter. Can be easily performed, and complete observation information can be easily obtained.
