Abstract

PURPOSE:To omit excess correspondence by providing a terminal station having a transmission means for a fault data, a transmission request means, a fault data collection end notice means and a fault monitor. CONSTITUTION:A fault monitor 13 at first sends a fault data transmission request to a terminal station 12-1. The terminal station 12-1 sends a transmission request to a succeeding station 12-2 in a received from when its own ID#1 and a received #N are dissident and its own station has no fault data. Finally a transmission request is sent from the terminal station 12-1 to a terminal station 12-N and a data collection end notice 29 is sent to the monitor 13 when the ID#N is coincident and no fault data exists. When the station 12-N has a fault, the fault data is sent to the monitor 13 together with ID#N. The monitor references the received ID to detect the coincidence of #N thereby discriminating the end of data collection. Through the constitution above, excess data correspondence between the monitor 13 and each terminal station is saved.

FIG. 1 shows a fault information monitoring system according to an embodiment of the present invention.

This system consists of N
The terminal station device 12-1 to 12-N includes terminal devices 12-1 to 12-N and one fault monitoring device 13. These terminal devices are assigned terminal device IDs #1 to #N, respectively, and fault monitoring by the fault monitoring device 13 is performed based on these IDs.

In the fault information monitoring system configured as above, the fault monitoring device 13 first
The first device to request transmission of fault data is determined. Here, the terminal device 12-1 is assumed to be the first device. In this case, the last device requesting transmission of failure data, that is, the highest failure data transmission device, is the terminal device 12-N.

FIG. 2 shows in detail the fault monitoring device 13 and the terminal station l2-1 in the fault information monitoring system shown in FIG. This fault monitoring device 13 is provided with a fault data transmission request sending unit l5, which sends an identification code (hereinafter referred to as a final fault data transmission request) indicating the final fault data transmitting device to the terminal device instructed by the destination instruction unit 16. A failure data transmission request 17 with an additional device ID (referred to as a device ID) is sent. This destination instruction section 16 includes an ID decoding section 1.
8 is connected and failure data 19 received from the terminal device
It is designed to decode the terminal equipment ID added to the terminal equipment ID. The terminal device ID 21 decoded here is input to the completion determination section 22 as well as the destination instruction section 16.

On the other hand, the terminal device 12-1 has a transmission data selection instruction section 24.
is provided, and a fault data transmission request 17 to which the final fault data transmitting device ID is added is manually input from the fault data transmission request transmitter 15 of the fault monitoring device 13. This transmission data instruction section 24 is a failure data sending section 25.
, the data collection completion notification sending unit 26, and the fault data transmission request transfer unit 27, and is configured to give an instruction to any one of these to execute transmission. Among these, when a transmission execution instruction is given to the fault data transmitting unit 25, it sends the fault data l9 of its own station to the ID decoding unit l8 of the fault monitoring device 13. When the data collection completion notification sending unit 26 is given a transmission execution instruction, it sends a data collection completion notification 29 to the completion determination unit 22 of the fault monitoring device 13 . Further, when a transmission execution instruction is given to the failure data transmission request transfer unit 27, the final failure data transmission device I is sent to the next terminal device 12-2.
The fault data transmission request 17 to which D is added is transferred in the form given from the fault monitoring device 13.

FIG. 3 shows how various data are exchanged between the devices of the fault information monitoring system shown in FIG. In this embodiment, as in the case of the conventional example, the terminal station l2
-2 and l2-5 have failure data, and other terminal equipment 12-1, 123, 12-4, l2-6 to 12-N
Assume that there is no fault data.

The operation of the fault information monitoring system configured as above will be explained with reference to FIG.

The fault monitoring device 13 first transmits a fault data transmission request 17-1 to which the final fault data transmitting device ID is added to the terminal device 12-1 (step 4 in FIG. 4). As mentioned above, the final failure data transmitter ID in this case is “#”.
N''.

The terminal device 12-1 that received this sends its own terminal device I.
D “#1” and received final failure data transmitting device ID “#
N” (step ■).

In this case, these do not match (step ■: N), and since there is no failure data in the local station (step ■: N), the final failure data transmitting device I
The fault data transmission request 17-2 to which D"#N" has been added is transferred in the form received from the fault monitoring device 13 (step (2)).

The terminal device 12-2 that received this sends its own terminal device I.
D and the received final fault data transmitting device ID are compared (step 2). In this case too, they do not match (
Step ■: N), since the own station has fault data <Step ■2 Y), sends the fault data 19-1 to the fault monitoring device 13 with the terminal equipment ID "#2" of the own station added. (Step ■).

The fault monitoring device 13 that received this information
Refer to D (step ■). In this case, the terminal device ID
Since "#2" does not match the final fault data transmitting device ID "#N" (step ■; N), the fault monitoring device 13 sends the terminal device 12-3 having the next terminal device ID "#3" to the terminal device 12-3. In response, it transmits a fault data transmission request 17-3 to which the final fault data transmitter ID "#N" is added (step (3) in FIG. 3).

The terminal device 12-3 that received this sends its own terminal device I.
D"#3' and received final failure data transmitting device fD"#
Compare with "N" (Step ■).

In this case as well, these do not match (Step ■: N), and there is no fault data in the own station (Step ■: N).
Final failure data transmitting device I to the next terminal device 12-4.
The failure data transmission request 17-4 to which D is added is transferred in the received form (step 2).

Similarly, since the terminal device 12-4 has no fault data, it transfers the fault data transmission request 17-5 with the final fault data transmitting device ID added to the next terminal device 12-5 ( Step ■).

The terminal device 12-5 that received this sends the message to the terminal device 12-2.
As in the case of , the terminal device ID "#5" of the terminal device itself is compared with the received final failure data transmitting device ID "#N" (step (2)). Although these do not match (Step ■: N)
, because the own station has fault data (step ■: Y),
Own terminal device ID “#5” for fault monitoring device l3
The fault data 19-2 with the added is transmitted.

The fault monitoring device 13 that received this information
Refer to D (step ■). In this case as well, the terminal device ID “#5” is the final failure data transmitting device ID “#N”
Since it does not match (Step ■: N), the fault monitoring device 1
3 transmits a fault data transmission request 17-6 to which the final fault data transmitting device ID is added to the next terminal device 12-6 (step 3 in FIG. 3).

Thereafter, in the same manner, the operations of steps (1) to (2) are sequentially performed in each terminal device.

Then, the fault monitoring device 13 or the terminal device 12 (N-1
) sends a failure data transmission request with the final failure data transmission device ID added to the terminal device 12-N.
, this terminal equipment ifl2-N has its own terminal equipment ID “#N
” and the final failure data transmitting device ID “#N” (step ■).

In this case, since they match (step 2: Y) and there is no fault data (step 2: N), a data collection completion notification 29 is sent to the fault monitoring device 13 (step 0).

Note that the terminal device 12-N, which is the most #faulty data transmitting device,
If there is fault data (Step 2; Y), the fault data is sent to the fault monitoring device 13 together with the terminal device ID "#N" (Step 2).

The fault monitoring device 13 that received this information
Refer to D (step ■). In this case, the terminal device ID
A match between "#N" and the final failure data transmitting device ID "#N" is detected (step 2: Y), and it is therefore determined that data collection is complete.

〔Effect of the invention〕

As explained above, according to the inventions recited in claims 1 and 2, each terminal device that is requested to send fault data transmits the fault data to the fault monitoring device only when there is fault data. However, if this is not the case, the next terminal device is requested to send the fault data, so that unnecessary data communication between the fault monitoring device and each terminal device can be reduced. Therefore, it is possible to prevent the line occupancy rate from increasing due to unnecessary data as in conventional systems.

Further, according to the invention as claimed in claim 3, since the fault data collection completion determination means is provided in the fault monitoring device,
The effect of being able to recognize the completion of failure data collection by receiving a data collection completion notification from the end station device or by comparing the identification code of the end station device that is the source of the failure data and the final failure data transmitting device identification code. There is.
