故障検出装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention provides a data highway system comprising:
In particular, the present invention relates to a data highway failure detection device that allows an operator to easily identify the cause of a failure occurring at a submaster station or a remote station (hereinafter referred to as a remote station).

障の要因を調べていた。 Generally, a remote station connected to a data highway is located in a location with poor environmental conditions and is far away from a master station. Conventionally, a failure occurring in a remote station was determined by detecting that there was no response from the remote station to a transmission from the master station, and this was determined by an operator. When operators learned of a malfunction at a remote station, they would go directly to the remote station where the malfunction occurred and investigate the cause of the malfunction.

類までは確認することができない。 However, depending on the cause of the failure, the equipment or parts to be repaired are often different, and furthermore, maintenance personnel are often different for hardware failures and soft failures. In this way, when a failure occurred in a remote station, the operator had to go all the way to the remote station to detect the cause of the failure, but with such measures, the distance to the remote station was long. This also has the disadvantage that it takes more time than necessary to repair the problem. Furthermore, conventionally, although it is possible to confirm the occurrence of a failure, it is not possible to confirm the cause or type of the failure.

Now, for example, when a "power-off" failure occurs in the remote station 12, the contact 61 in the transmitting device 32 that causes the failure is closed. As a result, this power-off failure cause signal is transmitted along with the station number 12 through the failure cause transmission lines 52, 50-1 to the contact input device 4 with a state change detector in the failure cause reception and transmission device 42 of the remote station 13.
8, and is then transmitted to the master station 2 through the transmission device 49 and signal transmission cables 24, 50-5. In addition, the host CPU 1 receives and discriminates the fault cause signal and station number 12 of the faulty remote station 12 transmitted from the master station 2, and accordingly issues an alarm from the fault cause alarm device 3 and displays "Station" on the display device 4. 12, the cause and location of the failure are displayed, such as ``Power outage failure occurred'', and the operator can immediately confirm this. Furthermore, if a malfunction due to "temperature abnormality" occurs in the remote station 12, the contact 64 is closed and the transmission line 5 that is the cause of the malfunction is closed.
2, 50-4 and is transmitted through the same process as described above and confirmed by the operator.

This eliminates the troublesome effort of having to detect a failure by using the system, and the operator can take appropriate measures against the failure in an extremely short period of time. Furthermore, since there is no need for the operator to directly detect the cause of the failure that has occurred, the burden on the operator is reduced and the maintainability and reliability of the system can be improved.
