た故障検出方式に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a failure detection method for equipment connected to a failure detection side through a wired transmission line, and particularly for equipment installed in remote locations or inaccessible areas. The present invention relates to a failure detection method that allows the failure detection side to easily identify the power supply operating status of equipment and the wired transmission line status.

マンド等を与え、その信号に対するレスポンスを解析す
ることにより故障検出が行なわれるようになっている。Until now, failure detection has been performed by giving a command or the like from one device to the detected side and analyzing the response to that signal.
故障検出のためには、特開昭６１−１３８４１号に示す
よりに、多種のハードフェアや複雑なアルゴリズムが要
されるようになっている。For failure detection, various types of hardware and more complex algorithms are required than those shown in Japanese Patent Laid-Open No. 61-13841.

ている。However, in the conventional technology, if the fault detection device does not return any response to the signal from the fault detection side, it is difficult to determine whether, for example, it is due to a power cut in the detection device. The failure may be due to an abnormality in the transmission line, but the failure detection side is able to identify the cause, but it takes a lot of unnecessary time to take measures against the failure.

し得ないものとなっている。By the way, there has been a known method for power outages in which a new line is added to the transmission line for ON/OFF signals of the power supply, thereby allowing the fault detection side to grasp the status of the power supply on the fault detection side. However, not only does the cable cost increase as the distance between devices increases, but if there is an abnormality in the transmission path, the failure detection side cannot identify the cause of the failure at all.

電源動作状態が故障検出側で容易に検出可とされた故障
検出方式を供するにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a fault detection method in which the state of a transmission path and the power supply operating state of a device on the fault detection side can be easily detected on the fault detection side.
上記目的は、被故障検出側機器電源断の際にはその機器
内で受信路と送信路とを短絡することで達成される。The above object is achieved by short-circuiting the receiving path and the transmitting path within the fault-detected device when the power is turned off.

あることが併せて知れるものである。The transmission line connection switching device installed in the fault-detected equipment forms a transmission line that allows both devices to communicate with each other when the power supply is normal, so various types of data are sent and received in both directions. It looks like this. However, if the power to the equipment on the fault detection side is cut off, the transmission line connection switching device switches the transmission line so that the data from the fault detection side is returned as is and sent to the fault detection side. be. As a result, if the power is cut off on the fault detection side, from the fault detection side's point of view, the signal sent by itself will be returned as is, so by returning the same signal as the sent signal, the fault detection side will receive the same signal. A power outage failure can be detected. In this case, it is also known that the transmission line is in a normal state at the same time.
以下、本発明を添付した図により説明する。 Hereinafter, the present invention will be explained with reference to the accompanying drawings.

Connected to side a by 5B,
It is ready for normal transmission and reception. That is, the data sent by the microprocessing unit (MPU) IA in device A is transmitted by two transmission adapters for asynchronous serial communication,

て説明すれば以下のようである。For example, if the data is a self-diagnosis function start command for device B, the self-diagnosis circuit 2B is activated, and the result is sent to the MPU IB and the asynchronous communication transmission adapter 4B.
, the transmission line connection switching circuit 5B, the transmission line, and the asynchronous communication receiving adapter 3Ai, and the MPUIAK is returned to detect a failure. Now, the operation when the power supply 6B in the device B is cut off in relation to the transmission line connection switching circuit 5B added in the device B according to the present invention will be described as follows.

The transmission line connection switching circuit 5B, which connects the transmission line to a@ in the normal state, switches it to the β side by means of a relay contact.

The transmission signal from PU1A is returned by the transmission line connection switching circuit 5B, and then transferred to the transmission line and the asynchronous serial communication adapter 3A.
f, which will be sent back via MPUIAK. Now, %MPU iA constantly monitors the received data, and if the received data is the same as its own sending data, MPUIA uses this to send device B.
It is known that the power has been cut off and equipment B is in an inoperable state. Furthermore, since the MPU IA has sent back its own data, it is also known that no abnormality has occurred in the transmission path.

上されることになる。In this way, the power status and transmission path status of equipment installed in remote or inaccessible locations! I can be identified without installing a new signal cable or using a complicated algorithm. Up until now, failures were seen as failures of some kind without a response, but other failures can now be detected as failures in specific parts, which will improve the efficiency of repair and maintenance.
