, 22-N becomes completely blind, and which of the monitored stations 22-1 to 22-N is the monitoring station 21?
There was a problem that it became impossible to grasp the status, such as whether or not the person had urgent information that needed to be sent.The present invention was made in view of the above points, and eliminates the above problems Even if a failure occurs in a monitoring station, the monitored station will detect the failure, and will quickly communicate the station number of the monitored station and the importance of the status change in stages, making it easier to improve operations and maintenance. An object of the present invention is to provide an apparatus abnormality monitoring method for an information transmission apparatus which can perform appropriate processing as quickly as possible and is inexpensive.

[Means for solving problems]

In order to solve the above problems, the present invention provides an information transmission device in which a fault in a monitoring station is detected by a monitored station, the monitoring station is notified of the fault, and the monitored station's own station number (
Alarm generating means that divides the importance of address) and state change 4 into stages and transmits them using an AC signal different from the FS signal, and an alarm signal receiving means that receives the signal generated from the alarm generating means. was installed at the monitoring station to monitor abnormalities in the information transmission equipment.

[Effect]

By configuring and monitoring device abnormalities as described above, even if a fault occurs in the monitoring station, the fault can be detected by the master station, and the station number of the monitored station itself and its status change can be detected. The severity is divided into stages and quickly transmitted by means of alarm generation.
Since the alarm is received by the alarm receiving means on the monitoring station side, appropriate processing in terms of operation and maintenance can be carried out as quickly as possible.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the system configuration of an information transmission device for implementing the device abnormality monitoring method according to the present invention.

In the figure, 1 is a controlled device, and 2 is the controlled device 1.
3 is an alarm generator connected to the master station 2, 4 is a transmission line for transmitting signals, 5 is a master station device, and 6 is a signal generated from the alarm generator 3. An alarm receiver 6 receives the alarm signal. Note that the monitored station 2 is connected to the transmission line 4.
Although a plurality of units are provided via the unit, illustration thereof is omitted.

In the information transmission device with the above configuration, the monitored station 2 constantly exchanges information with the monitoring station device 5 via the transmission path 4 using the FS communication method, so that abnormalities in the status of the monitoring station device 5, that is, failures, are detected. When a state change occurs in the controlled device 1, the monitored station 2 outputs a command to the alarm generator 3. The alarm generator 3 has a P-B signal (button button signal) output function,
P- of the required number of digits (station number of own station, importance of status change, etc.)
The B signal is sent to the transmission line 4. The alarm receiver 6 is connected to this P-
It has a function to receive the P-B signal and determine the station number of the monitored station 2 that is generating the P-B signal and the importance of the status change. It is possible to know whether the monitored station 2 has information to be transmitted to the monitoring station device 5, and to determine the importance of the state change. This will speed up the maintenance system. For example, if the station number of the monitored station 2 is l″01, then the next third digit is added with the importance of the status change categorized into 10 levels from 0 to 9, and the alarm generator 3 The alarm receiver 6 receives the signal to check the device.

Note that the signal generated from the alarm generator 3 is an AC signal different from the FS signal.

By configuring as described above, a failure of the master station device 5 can be detected at the monitored station 2, and if there is information that must be transmitted from the monitored station 2 to the monitoring station device 5, the importance of the information can be determined. This information is transmitted to the alarm receiver 6 on the monitoring station side, so that the alarm receiver 6 does not blindly grasp the state of the object where the alarm signal is being generated.

Note that the visual system for detecting device abnormalities in the information transmission device according to the present invention can be implemented easily and inexpensively by simply providing the alarm generator 3 on the monitored station side and the alarm receiver 6 on the monitoring station side, so it is generally applicable. It can also be applied to information transmission equipment and remote monitoring and control equipment.

〔Effect of the invention〕

As explained above, according to the present invention, a failure in a monitoring station is detected by the monitored station, and when there is information that needs to be transmitted to the monitoring station, the importance of the information is added and the alarm receiver on the monitoring station side Since the monitoring station side can determine the monitored station where the alarm signal is generated and the importance of the information, it is possible to inexpensively implement an equipment abnormality monitoring method that can grasp the status of the monitored station even in the case of a master station failure. It has the excellent effect of being able to be constructed.
