Description

TECHNICAL FIELD The present invention relates to a monitoring and transmitting apparatus for remotely monitoring the operating state of equipment such as communication equipment and transmitting the result.

[Conventional technology]

For example, in a monitoring and transmitting device for remote monitoring of communication equipment, external input information sent from the communication equipment is sampled and input at fixed intervals, and the status change data is returned by polling on the center side or the center side. The call is voluntarily sent to. During the period from the transmission of the state change data to the transmission of the next state change data, the alarm occurrence information may be obtained as significant information by sampling the input information. Conventionally, such significant information generated during transmission may be added to the data file being transmitted and transmitted, but basically, the amount of data proportional to the amount of change in input information is transmitted. It was like this.

[Problems to be Solved by the Invention]

As described above, the conventional monitoring and transmitting apparatus employs a method of transmitting an amount of data according to the amount of change in the input information. In the case of an ordinary monitoring system which is premised on the average of a certain amount of data generation probability, the sensor receiving the data can sufficiently process the data. However, when the monitored target is microwave radio-related equipment, if a sudden radio interference such as fading occurs, the signal from the related communication device is generated due to the alarm occurrence of the original communication device. A lot of alarms are generated due to intermittent operation. In such a case, the processing load on the supervisory transmission device that collects these pieces of information and the computer on the center side that processes the information is significantly increased, and there is a problem that the processing capacity is exceeded or the processing is delayed. It caused it. In addition, it is costly to install a device having a large processing capacity in anticipation of such a situation, which causes an economical problem.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a monitoring and transmitting apparatus that does not cause an excessive burden on information processing even if significant information frequently occurs.

[Means for Solving the Problems]

In the present invention, (i) a current data file that stores the current state of the input data supplied from the monitored object, and (ii)
A first-stage transfer file that stores data to be transferred and attribute information indicating whether the data has been transferred or is in a state of waiting for transfer, and (iii) data is transferred from the first-stage transfer file. A second-stage transfer file for storing data to be transmitted to the communication line and attribute information indicating whether the data has been transferred or is waiting for transfer, and (iv) the input data described above. When writing to the first-stage transfer file, if there is no change compared with the data already stored in the first-stage transfer file, this input data is not stored, and if there is a change, the first
First-stage transfer file storage control means for referring to the corresponding attribute information of the stage-transfer file and storing the input data as it is if the transfer has been completed, and adding to previous data when waiting for transfer And (v) when the data stored in the first stage transfer file is transferred to the second stage transfer file, there is no change compared with the data already stored in the second stage transfer file. This input data is not stored in, and if there is a change, the corresponding attribute information of the second stage transfer file is referred to, and if it has been transferred, this input data is stored as is The second stage transfer file storage control means for adding to the previous data, (vi) the state change amount counter for counting the state change amount of the input data, and (vii) the state change amount counter for counting. value A function value as a variable, is provided to monitor the transmission apparatus and a time counter for determining a sampling period of the data output from the first-stage transfer file to perform the transfer to the second stage transfer file.

That is, in the present invention, when the input data is stored in the first stage transfer file, data that does not change is not stored and discarded,
Regarding the changed data, if the data before the transfer does not exist, it is stored as it is, and if the data before the transfer exists, it is added to this and the amount of the data is kept constant. Further, in the present invention, the second stage transfer file is provided to suppress the transfer amount of data from the first stage transfer file to the second stage transfer file. Therefore, a state change amount counter and a clock counter for counting the state change amount of the input data are provided. That is, the state change amount per unit time (for example, the state change amount of 30 seconds to 60 seconds during which a certain amount of alarms can be collected) is stored as an independent variable in the first transfer file according to the size of the function value. Controls the sampling second interval of data.

Therefore, even if a large number of alarms occur, the amount of data sent to the center does not increase, and it is possible to prevent a transient load from being applied to the processing of information.

〔Example〕

 The present invention will be described in detail below with reference to examples.

FIG. 1 shows a basic configuration of a surveillance system using a surveillance transmission device according to an embodiment of the present invention. External input information 12 obtained from a monitored object 11 such as communication equipment in this system is input to the monitoring and transmitting apparatus 13 of this embodiment. The supervisory transmission device 13 includes a central processing unit (CUP) 14 and is connected to the following units by an internal bus 15.

(I) Timing generation unit 16: a unit for generating timing such as data sampling.

(Ii) Communication control unit 17: connected to the center side (not shown) through the communication line 18,
This is a part for transmitting data.

(Iii) Input unit 19: a circuit unit for inputting the input data 12 sent from the monitoring target 11.

(Iv) Storage unit 21: A unit for storing programs for performing various controls of the monitoring and transmitting apparatus and temporarily storing data such as input data.

FIG. 2 is for explaining the process of processing the data input to this monitor transmission device. In this figure, the input data 12 is stored in the current data file 23 in the storage unit 21 shown in FIG. However, this input data 12
Is compared to the previously stored input data. If there is no change between these data, the data is not stored in the data file 23 at present and is discarded as indicated by the arrow 24. On the other hand, if there is a change between these data, the input data 12 is stored in the current data file 23. At this time, data storage or data addition processing is performed by referring to the attribute information of the relevant part of the first-stage transfer file 25.

FIG. 3 shows details of the transfer file shown in FIG. The transfer file constituting the storage unit 21 (FIG. 1) is composed of a first stage transfer file 25 and a second stage transfer file 26 described later. In the first-stage transfer file 25, data storage locations for storing data D ₁ i, D ₁ i ₊₁ , ... And attribute information for storing attribute information A ₁ i, A ₁ i ₊₁ , .... The storage locations are provided in pairs.
Also in the second transfer file 26, the data storage location for storing the data D ₂ i, D ₂ i ₊₁ , ... And the attribute information for storing the attribute information A ₂ i, A ₂ i ₊₁ ,. The storage locations are provided in pairs.

Returning to FIG. 2, the explanation will be continued. When the input data 12 is stored in the current data file 23, the first transfer file 25
As a result of checking the corresponding _one of the attribute information A ₁ i, A ₁ i ₊₁ , ... of the attribute information, if it is “transferred”, the input data (for example, D ₁ i) is stored. On the other hand, in the case of “waiting for transfer”, the input data 12 is logically added to the data (for example, the data D ₁ i) existing at the relevant portion and the added data is stored. For example, if the occurrence of an alarm is logical "1", the corresponding data will be logically "1" by the input indicating the occurrence of the alarm.
And store.

By the way, the input data 12 must be sampled and input at such a frequency that the alarm information of the monitored object 11 is not missed, but the data transfer 28 from the first stage transfer file 25 to the second stage transfer file 26 It is sufficient to set the sampling timing of about 1 second cycle as the basic timing. The contents of the first-stage transfer file 25 are transferred to the second-stage transfer file 26 at such timing.

The transfer order of the data D ₁ i, D ₁ i ₊₁ , ... is as follows.
That is, first, the second-stage transfer file 26 shown in FIG.
Based on the attribute information A ₂ i, A ₂ i ₊₁ , ... In, it is determined whether the data has been transferred or is waiting to be transferred. And, in the case has already been transferred, the data _{D 1 i, D 1 i +1} , the contents of the ...... data D ₂ i, D ₂ i
Transfer so that it becomes ₊₁ .... On the other hand, in the data transfer waiting state, the contents of the data D ₁ i, D ₁ i ₊₁ , ... Are added to the data D ₂ i, D ₂ i ₊₁ ,. That is, logical addition processing is performed. The contents of the data D ₂ i, D ₂ i ₊₁ , ... In the second-stage transfer file 26 are extracted and transmitted at the timing when they are transmitted to the communication line 18.
At this time, the attribute information A ₂ i, A ₂ i ₊₁ , ... Is changed from “waiting for transfer” to “transferred”.

FIG. 4 shows two types of counters used in this monitor transmission device. These are state variables counters
31 and a clock counter 32. The state variable counter 31 is a counter that counts the state change amount, and is incremented under the control of the CPU 14 each time a state change of the input data 12 is detected. The clock counter 32 counts the time when a predetermined time of 30 seconds or more is timed up. Then, every time the time is up, the sampling value of the data output from the first-stage transfer file 25 for transferring to the second-stage transfer file 26 is a function value using the count value of the state variable counter 31 as a variable. To decide. Thereby, automatic suppression control of the input state data is realized. The suppression operation speed can be controlled by changing the value of the time-up time T of the clock counter 32. For example, when the value of the time-up time T is small, the control response becomes fast, and conversely, when it is large, the control response becomes slow.

〔The invention's effect〕

As described above, according to the present invention, the input data for each unit time is added by the two-stage addition mechanism of the input information, the state change counter for counting the state change amount of the input information, and the clock counter for defining the counting time. Then, the amount of state change is obtained, and the addition timing of the two-stage addition mechanism is adjusted using this as a parameter. As a result, it is possible to realize automatic control of suppression according to a change in the state of input information. Therefore, in a monitoring and transmitting apparatus targeted for monitored equipment such as microwave communication equipment that frequently generates an alarm when a radio wave is disturbed, the effect of avoiding an increase in the size of equipment on the center side is suppressed by suppressing input data. Further, in the present invention, since the suppression of the input data is performed by the addition processing, the alarm information is not missed and the safety can be secured.
