DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 1: 1 or 1: N multi-drop or regenerative relay transmission system in which a plurality of transmission devices are interconnected via a transmission line.
The present invention relates to a remote monitoring control transmission device that transmits information necessary for monitoring control between transmission devices and performs monitoring control of a controlled device.

2. Description of the Related Art Conventionally, a 1: 1 or 1: N multi-drop or regenerative repeater type transmission system is connected to a plurality of transmission devices via a transmission line, and information necessary for monitoring and control is provided. In a transmission device that monitors and controls a controlled device by transmitting data to each other, the device (own station) was connected to the transmission line when conducting a test to confirm information transmission / reception and a line confirmation test. . In this case, when the device falls into a state of being out of operation due to a failure or maintenance, the entire system becomes inoperable, and thus no test was performed during operation.

[0003] Further, even if a test can be performed during operation, whether transmission or reception of information between transmission devices is possible or not is determined based on local diagnosis results of transmission devices involved in transmission and reception. The normal / abnormal state of the transmission device can be ascertained only by transmitting and receiving information between related transmission devices.

In recent years, a plurality of transmission apparatuses are connected via a transmission line to form a 1: 1 or 1: N type multi-drop or regenerative relay type transmission line. In transmission equipment that transmits and receives necessary information to monitor and control controlled equipment, the amount of information increases due to the increase in size and sophistication of the system, and high-speed and high-efficiency information transmission. Higher quality is increasingly demanded with the development of products.

In a system in which transmission devices are mixed and used for operation or test on a transmission line, the system must be stopped to confirm information transmission / reception and line confirmation on a trial basis. This has a significant effect on the system in operation and requires high local adjustment costs.

Therefore, the self-diagnosis is performed before connecting to the device, or the self-diagnosis result as to what caused the failure even when the system was stopped due to a sudden failure of the device during operation. Is required to be accurately grasped by the host device. This is because the replacement parts can be promptly secured, and as a result, the time required for restoration and the like can be reduced.

[0007] In addition, even for a device that newly joins the system, if a sudden failure occurs due to the device, a high level of reliability should be maintained to keep the operating system in a normal state. Is required.

On the other hand, when information is transmitted and received between transmission apparatuses connected to a regenerative relay type transmission path, a transmission apparatus which regenerates and relays information on the way along the transmission path as well as a diagnosis result between the opposing apparatuses. If the diagnosis of the system as a whole, such as the state of the transmission line and the state of the transmission path, has not been made in advance, an abnormality at a specific location causes transmission congestion, which greatly affects the system.

Furthermore, even if the latest state of the transmission state can be ascertained, it has not been possible to ascertain the statistical state of an accidental failure factor when viewed at long time intervals.

Accordingly, it is an object of the present invention to provide a remote monitoring and control transmission device having a self-diagnosis function with excellent reliability and maintainability.

In order for the transmission device 134 to transmit the information of the own station, the own device mode is added to the destination address by the own device mode adding means 82, and the destination address is set to the transmission information by the address setting means 91. Further, in order to perform the mode comparison, the mode comparing unit 83 extracts the mode from the destination address of the received information received via the receiving unit 2 and compares the mode with its own device mode. For example, in the case of processing received information received from another station or branch processing of reproduction relay or discarding, the mode extracted from the destination address of the received information received via the receiving means 2 and the operation / test setting means 81
Is compared by the mode comparing means 83, and the comparison result is notified to the reception information branching means 84. The reception information branching unit 84 branches the reception information as described above with reference to FIG.
