Description

[Detailed Description of the Invention] [Summary] Regarding a maintenance system that uses highly directional radio waves, it is possible to easily obtain fault information from multiple devices when the occurrence of a fault is recognized, and to identify the source of the fault. The purpose of this system is to quickly recognize the equipment by transmitting the occurrence of a fault in the equipment to be maintained to the maintenance terminal using a wireless signal, and responding to the fault detailed information request signal and the detailed information request signal from the maintenance terminal. The system was configured to transmit and receive response signals using highly directional radio waves.

[Industrial Application Field] The present invention relates to a maintenance system that uses highly directional radio waves, and in particular relates to a method for obtaining fault information when a fault occurs in multiple related devices.

In a device where a failure has occurred (the transmitter will be explained below as an example), for example, there are methods to check whether the signals in each part of the circuit are as specified, or to check each circuit through test signals. Detecting the point of failure by detecting the point of failure by looping back the signal and testing the next circuit one by one if the returned signal is normal. will be held.

[Conventional technology]

A conventional maintenance method will be explained using FIGS. 6 and 7.

When a failure occurs in a device to be maintained (for example, a transmission device), the failure is detected by the CPU 2 O5, and the operator is notified by, for example, a buzzer sound or lighting of a lamp. This buzzer sound and lighting of the lamp prompt the operator to take trouble recovery action (maintenance).
I do. First, connect the maintenance terminal and measuring instrument to connectors 203 and 205 and cable 2 to the equipment to be maintained where the failure has occurred.
04 as shown in FIG. In this connected state, a single operation on the keypad 209 of the maintenance terminal starts a search for the hot spot where the failure has occurred.

For example, as mentioned above, if a test signal is sent out and the signal is looped back at each stage of the circuit, if the loopback information is not returned normally and it is determined that there is a fault in that circuit part, the test signal is Each time it is sent, the result is detected by the CPU2O5, and the result is detected by the input/output interface (hereinafter described as I10).
2 (12, connector 203, cable 204, connector 205, l1 (1206) is input to the memory 207, and after being held at - time, is output to the CP IJ 208 and the display 210. According to the content displayed on the display 210 , instructs to send the test signal again, or if a fault is detected, performs maintenance on the fault point.

[Problem B to be solved by the invention] In the conventional maintenance method as described above, when a failure occurs in one device, it is possible to easily connect the device and the maintenance device on a one-to-one basis. It is possible, but a failure that occurs in one device will spread to other devices (devices that are related to each other)
When such a failure occurs, it is difficult to know where the failure is occurring among multiple devices to be maintained, and it is necessary to connect a maintenance terminal to each device one by one and investigate the source of the failure. It is what it is. However, it is a difficult task to connect a maintenance terminal to a plurality of devices each time a failure has occurred through a connector and to investigate the location where the failure has occurred.

Therefore, it is an object of the present invention to make it possible to easily obtain fault information from a plurality of devices when the occurrence of a fault is recognized, and to quickly recognize the device that is the source of the fault.

A detailed explanation will be given below with reference to FIGS. 2 to 5.

Here, when a failure occurs in one of the multiple devices to be maintained, the CPU of the device to be maintained where the failure occurs
A fault is detected at ll0, and a signal indicating the occurrence of the fault is input to the radio modulator 22 via a section 110 (input/output interface). The wireless modulator 22 modulates the input failure occurrence information into a wireless signal and transmits it to the maintenance terminal via the antenna 31. As shown in FIG. 5, this is configured so that when a failure occurs in a plurality of maintenance target terminals, failure occurrence information is sequentially transmitted to the maintenance terminals. Here, a case will be described in which a failure occurring in a higher-level device, such as a transmission device, spreads (affects) lower-level devices, and a case in which failure information occurs simultaneously in a plurality of devices will be described.

First, as shown in FIG. 4, fault information from each device to be maintained is sequentially input to the maintenance terminal. (Above) In the maintenance terminal, failure occurrence information is received from each device to be maintained via the antenna 61, and the radio demodulator 71 demodulates the radio signal and converts it into an electrical signal. Failure information is transmitted to the CPU 81 via the memory 73. The CPU 81 recognizes the fault information as shown in FIG. 4 and displays it on the display 101.

The maintenance person recognizes the occurrence of a failure in the device to be maintained by the display 101, and presses the keypad 91.
to output a fault detailed information request signal to the equipment to be maintained where the fault has occurred. This failure detailed information request signal is input to the ultrasonic modulator 113 via the 110 unit 111, converted into a highly directional ultrasonic signal, and output to the speaker 122 via the hybrid circuit 121. The speaker 122 sends the input fault detailed information request signal to the equipment to be maintained where the fault has occurred. In the equipment to be maintained, a detailed failure information request signal is received by the speaker 52 and outputted to the ultrasonic demodulator 43 via the hybrid circuit 51. The ultrasonic demodulator 43 converts the input ultrasonic signal into an electrical signal and outputs it to the CPUll0 via the 110 section 41. In the CP UIIO, in response to the fault detailed information request signal inputted as shown in Figure 4, the detailed fault information indicates, for example, whether the currently occurring fault occurred internally or externally (related to other devices). A signal indicating whether the fault has occurred and a signal indicating where within the fault has occurred are outputted to the ultrasonic modulator 42 via the 110 section 41.

The ultrasonic modulator 42 modulates the input detailed information on the fault into a highly directional ultrasonic signal, which is output to the maintenance terminal via the hybrid 51 and speaker 52.

In the maintenance terminal, detailed information on the failure is received from the terminal to be maintained through the speaker 122, and is outputted to the ultrasonic demodulation circuit 113 via the hybrid 121. The ultrasonic demodulation circuit 113 converts the input detailed information on the fault into an electrical code and outputs it to the memo 30 and the CPU 81 via the 110 section 111. In the memory 130, detailed failure information for each device input as described above is recorded. As shown in FIG. 4, the CPU 81 displays instructions for identifying the device that is the source of the failure from the received detailed failure information for each device, or for quickly recovering from the failure in case of an emergency failure. Notify the operator via the system and perform trouble recovery work.

In another embodiment, infrared modulators 45, 115, infrared demodulators 46, 114, light emitters 53, 124, and light receivers 54, 123 as shown in FIG. , generates a detailed failure information request and its response signal, and transmits and receives them.

The present invention is not limited to the highly directional radio waves shown in the above embodiments.

[Effects of the Invention] According to the present invention, it becomes possible to transmit and receive fault information by matching the directions of the directional signals of the maintenance terminal and the maintenance target terminal. Therefore, it becomes easy to collect fault information from a plurality of terminals to be maintained where a fault has occurred. Further, in the present invention, since the input failure information is analyzed on a device-by-device basis, maintenance for failures in devices with high importance can be carried out preferentially.
