The remote communication device 106 that accepts this command, as shown in FIG. 9 (c) (D), changes the connection of the video channel of the camera 102 to the logical channel of VPIX. This action is also implemented by rewriting the valid / invalid flag bit 2019 of the table (I T 1) 2017 previously explained. That is, the remote communication device 105-accepts this command, rewrites the valid and invalid flag bit 2019 of the reference object of P = 〇 'VP IX, VC IX to "invalid" of " 0 ", and p = l, VPIx, VC IX's reference target is valid • Invalid flag bit 20 19 is rewritten as '1' of the "valid". As a result, the logical channel set to change the unit to the transmission path 1 12 from the camera 101 is set to change the unit to the transmission path 1 1 2 from the camera 102. With this configuration, unselected images are not output on the transmission path 1 1 2. Therefore, one logical channel VP IX, VCIX can be shared, and one of the plurality of image information can be selected and displayed on the monitor device 1 1 0.値 During this image switching, in the AAL 1 C LAD section 2 0 2 5 of the central communication device 1 0 9, the unit input is interrupted before and after the switch, and units from different information sources are input. Although not described in detail, in the AAL 1 communication protocol, the lack of units and their mixing according to the sequence number is detected.

Therefore, when this camera is switched, it is necessary to reset the AAL 1 C LAD section 2 0 2 5. _ „This resetting opportunity is performed when the unit input is interrupted. Figure 10 shows the reset sequence of the CLAD section 2 0 2 2 switched by the image. First, the switch command ① of W① is generated and the input of the switch command unit is interrupted The unit input interruption alarm is transmitted to the control unit 208 as an interruption signal.

Description of the invention (17) (Please read the precautions on the back before filling out this page) The ring is' but not limited to this. Also, although there are 1 remote communication devices 1 0 5 ~ 1 0 8 is connected to one camera, but it is also possible to connect two or more cameras to constitute it. _ _ In addition, those connected to the remote communication device 105 to 108 may be other than cameras. Other information output devices. However, a plurality of remote communication devices, such as 105 to 108, are connected by a transmission path, and the start and end points of the transmission path are connected to form a circular transmission path. In the image transmission system, for example, the case of using optical fiber as a transmission medium is taken as an example. 'Because of the relationship between the intensity of the optical output of the transmission device and the attenuation of the optical fiber, the distance between the transmission devices is limited. In general, consider a linear transmission of a plurality of transmission devices ① to 传送 an image transmission system connected by a circular transmission path 121, and define the direction ①—⑦ as the way out, and the direction ⑦—① as the loop, and let ds be the transmission device The distance between them is the largest, and the distance dp of the loop needs to be less than ds. Therefore, the total length of this image transmission system is less than ds. C Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Therefore, a long-distance image transmission system is constructed linearly. Considering the amount of attenuation, as shown in FIG. 12, a repeater 1 3 1 is arranged in the middle of the loop for amplification. As shown in FIG. 13, it must be pulled in once in the transmission device 1 4 1 Teleport to teleport. The repeater 1 3 1 in FIG. 12 is formed by the optical-electrical conversion section 1 3 1 1 and the relay processing section 1 3 1 2. Moreover, each transmission device is formed by the optical-electrical conversion section 1 3 1 1 and the demultiplexing section. 1 3 1 3 formed. In addition, the paper size shown in Figure 13 applies to the Chinese national standard (CNSM4 specification (210x 297)) 411665 A7 B7 V. Description of the invention (18) Each transmission device 141 consists of two sets of optical and electrical conversion sections for the return path and the return path 1 4 1 1 is formed with the multi-channel separation unit 1 4 1 2 to combine the two transmission paths of the outgoing and return circuits. The optoelectric conversion unit 1 4 1 1 needs a circuit. In this way, a long-distance image transmission system is constructed linearly. At this time, it is conventional to configure a repeater, and it is necessary to once pull the transmission path into the transmission device to transmit it. According to this structure, the structure of the transmission device becomes complicated and the cost becomes high. 'In the embodiment shown below, this is an image transmission system that does not complicate the structure of the transmission device, can communicate over long distances, and does not interrupt communication even if an accident such as a power outage or disaster occurs. 15 shows other embodiments of the image transmission system of the present invention. In FIG. 15 (A), regarding the image transmission system of this embodiment, the node number ① to ⑦ of the transmission device 1 5 1 to 1 5 7 are The arrangement is linear, and each of the transmission devices 1 5 1 to 1 5 7 is set so that the clockwise direction (loop) and the counterclockwise direction (outgoing direction) are different from each other. That is, the transmission device 1 defining the node number ① arranged at the starting point is defined. 51 is the No. 1 node, and the transmission device of the number ⑦ located at the end point 1 5 7 is the N-th node, and the transmission devices 151, 153, 155, and 157 defined by the odd node number are sequentially arranged at The circular transmission path 1 5 8 is clockwise, and the transmission devices 1 52, 1, 54 and 1 56 defined by the even node number are arranged in the anti-clockwise direction.

Description of the Invention (19), the transmission devices 1 5 1 to 1 5 7 from the node number ① to ⑦ are arranged in a writing and each transmission device 1 5 1 ~ 1 5 7 is set to clockwise (loop) An example that is different from the counterclockwise direction (going off) In the forward transmission path, the transmission devices 1 5 2 ′ 1 5 4, 156 are connected, and in the loop transmission path, the transmission devices 157, 155, 153, 151 are connected. Figure 16 is the opposite of the number of nodes arranged in the outbound and return paths. Figure 15 (A) is the opposite, and the transmission devices defined by the even node numbers 1 5 2, 1, 5 4, 1 5 6 are sequentially arranged in the ring transmission. In the clockwise direction of path 1 58, the transmission devices 1 5 1, 153, 155, 157 defined by the odd node numbers are arranged in the counterclockwise direction. In the case of such a node arrangement, as shown in FIG. 17, the transmission device No. k-2, the transmission device No. k, and the transmission device No. k + 2 are connected adjacently, respectively. In this case, although the maximum distance between the transmission devices is ds (m), but the transmission devices of the odd node number and the even node number are separated by 1 configuration, the total extension of the image transmission system can be greatly extended compared with the known person . When the processing between the transmission devices is within d s (m), they may be arranged adjacent to each other between odd-numbered node devices or even-numbered node devices. For example, it is also possible to connect 152, 153, 154, 156 in the outbound transmission path and 157, 155, 151 in the return transmission path. In addition, in each of the transmission devices 1 5 1 to 1 5 7, it is sufficient to accommodate the transmission path of either the forward path or the return path, as shown in FIG. 18.

Description of the invention (20) It is only necessary to change the departments 401 and 402. By doing so, the configuration of each transfer device can be simplified, and costs can be reduced. As shown in FIG. 19, for example, even if the power supply of the transmission device 1 5 4 of the node number ④ is stopped, the transmission device 1 5 2 and the transmission device 1 adjacent to the transmission device 1 5 4 5 6 is turned back, and communication across the transmission device 1 5 4 can continue. Because the transmission path of this circuit is not pulled into the transmission device 154, it will not be affected by the failure of the outgoing path. The image transmission system as described above can be applied to, for example, a signal system arranged along a railway. In this signal system, the transmission medium between transmission devices uses optical fiber as much as possible. Furthermore, in order to improve the reliability of the signal system, a transmission path with a double loop structure of the current system and the backup system is used. Here, the current system is used for clockwise rotation, and the preparation system is used for anticlockwise rotation. Two optical fibers are required. Generally, the optical fibers between the transmission devices are optical fiber cables that use tens to hundreds of cores of optical fibers to form a single cable. Therefore, many optical fibers in the current system and the preparatory system are accommodated in the same cable. Or it is characterized by being arranged in a straight line and will be arranged in the same side trench or overhead wiring. In this case, due to disasters or accidents such as landslides, it is unavoidable that the system in which the active and standby transmission paths are simultaneously cut off will crash. Therefore, the optical fiber cable connected to the transmission device configured in a clockwise rotation and the optical fiber cable connected to the transmission device configured in a counterclockwise rotation are dispersedly arranged at different positions, for example, the upstream side and the downstream side.

Description of the invention (23) Because it is cut off, it is the same as usual. However, the transmission path from the terminal 802 to the current system of the terminal 801 is switched and cannot be used. — — That is, the current transmission path from the transmission device 1 5 4 to the transmission device 1 5 2 is cut off 'so FIG. 2 5 CA) (B)' by the transmission device 1 5 4 and the transmission device The circuit return switching means of 1 5 2 is 9 0 2 and the transmission path is switched to the reserve side for circuit return.
