Abstract

PURPOSE:To shorten processing time by correcting monitoring time when the control response is not inputted within monitoring time in a telemeter telecontrol system. CONSTITUTION:Control response from an observation master station 4 is monitored by a control response monitoring part 13. When control response is not inputted within monitoring time, correction time is counted by a correction time counting part 15. Then, the correction time is added to the monitoring time of the monitoring time table inside a monitoring time RAM memory 14 by the control program of a processor 11. Thus, the monitoring time of the control response monitoring part can be set to the optimal value which is suitable for the actual condition since the monitoring time is corrected in this way. Therefore, the processing time can be shortened since useless time such as retrial is not observed.

Description

DETAILED DESCRIPTION OF THE INVENTION +al Technical Field of the Invention The present invention relates to a control response monitoring time correction method for correcting the monitoring time of a control response signal in a telemeter/telecontrol system.

(bl Background of the Technology) Conventional telemeter/telecontrol systems transmit observation data from a remote observation station with a large number of observation measuring instruments to a master observation station that collects information.
This is a system that records transmitted data on a data recorder, pen recorder, etc., and the processing device performs data processing such as controlling the observation master station, controlling the observation data recorder, and compiling various statistical three-day reports. In this observation data control method using the processing device, the control program of the processing device instructs the observation master station to control, the observation master station controls each observation slave station, and the control response from the observation slave station is sent to the observation master station. received by the master station,
The observation master station sends a control response back to the processing device, and the processing device performs control processing on observation data based on the returned control response.

Observation data processing is performed based on control instructions from the processing device and control responses from the observation master station. Therefore, a response monitoring function for monitoring the response time from sending out this control instruction to receiving a control response is attached to the processing device, and is controlled so that the entire system operates smoothly and processing time is not wasted.

(C1 Prior Art and Problems) This type of telemake/telecontrol system is explained below. Figure 1 shows a conventional telemeter/telecontrol system.
The block diagram of the telecontrol system is shown. 1 is a processing device, and the control processing unit 2 of the processing device 1 sends a control instruction to the observation master station 4 via the interface unit 3, and the observation slave station 5 designated by the control of the observation master station 4 control. In this figure, observation slave station 5 is shown for ease of understanding.
will be explained as one station. The observation slave station 5 sends a control response to the observation master station 4, and the observation master station 4 receives the control response.
The control response is sent to the control response monitoring unit 6 of the processing device 1. By receiving the control response in the control response monitoring unit 6 and notifying the control processing unit 2.

The processing device 1 processes observation data. The monitoring until receiving the control response from the observation master station 4 is as follows.

The monitoring time is defined by the monitoring time ROM memory 7 which stores a monitoring time table in which the monitoring time is predetermined, and the quantity control response monitoring unit 6 monitors the input of the control response for the specified monitoring time, and controls the control within the specified time. If there is no response input,
The control processing unit 2 is notified to try again. However, in this conventional control response monitoring method, the monitoring time is based on a fixed monitoring time table set in advance, and even if control is performed according to control instructions and a nose trial is performed when there is no control response within the monitoring time, This has the disadvantage that the monitoring is repeated at the same monitoring time as the monitoring time, and the monitoring time is doubled, resulting in wasted time, and the processing time of the entire telemeter/telecontrol system becomes longer.

(d) Object of the Invention The object of the present invention is to solve the drawback that the conventional fixed monitoring time increases the processing time of the entire system.

(e) Structure of the Invention The above object is to provide a control response monitoring unit that monitors control responses sent from an observation master station that controls a plurality of observation slave stations and sends out a monitoring response (fj, number); A monitoring time RAM memory that stores a monitoring time table that sets the monitoring time of the response monitoring section, and a correction time that measures the correction time of the actual response time until the control response is input based on the monitoring response signal from the control response monitoring section. a measurement unit, a monitoring time correction panzer memory for storing the correction time measured by the correction time measurement unit at a specified address, and an addition instruction bit at a specified address for adding the correction time to the monitoring time table in the monitoring time RAM memory. A processing device for a telemeter/telecontrol system, comprising a control program having means for turning on a control program, which transmits a monitoring response abnormality signal when a control response is not input from the control response monitoring section within a monitoring time;
The correction time measuring unit measures the correction time based on the monitoring response abnormality signal, stores the measured correction time in the monitoring time correction buffer memory at a designated address, and the control program of the processing device reads the addition instruction bit at the designated address. This is achieved by the present invention, which is configured to turn on the monitoring time table and add the correction time stored in the monitoring time correction panzer memory to the monitoring time table at the specified address in the monitoring time RAM memory.

That is, in a processing device of a telemeter/telecontrol system that processes observation data based on control responses from an observation master station that controls a plurality of observation slave stations, a control response monitoring section monitors control responses from the observation master station. Then, when a control response is not input within the monitoring time, the correction time is measured, and the control program of the processing device adds this correction time to the monitoring time in the monitoring time table to correct the control response. The control response monitoring time allows you to set the monitoring time of the monitoring unit to the optimal value that suits the actual situation, eliminating the need for retries and wasting time, and shortening the processing time of the entire telemeter/telecontrol system. This provides a correction method.

(f) Example of the Invention An example of the present invention will be described below. FIG. 2 shows a block diagram of a processing apparatus according to the present invention, and the same objects are designated by the same reference numerals as in FIG. 11 is a processing device; 12
13 is a control response monitoring section, 14 is a monitoring time RAM memory, 15 is a correction time measuring section, 16 is a monitoring time correction buffer memory, 17 is an addition instruction hit, and 18 is a message output device. Processing device 11 and observation master station 4
Control instructions and control responses are sent and received between the two. A control program for turning on the instruction bit of the specified address of the addition instruction bit 17 is added to the control program of the control processing unit 12. The control response monitoring unit 13 is a reception monitoring unit that receives a control response from the observation master station 4, and monitors the control response during a specified monitoring time, and when a control response is input within the specified time, The real time is output as a message to the control processing unit 12.

Furthermore, if a control response is not input within a specified monitoring time, a monitoring response abnormality signal is sent out.

The monitoring time RAM memory 14 is a memory that stores a monitoring time table that defines the specified monitoring time of the control response monitoring section 13 and the upper limit monitoring time. Correction time measurement unit I5
measures the correction time of the actual response time until the control response is input based on the monitoring response abnormality signal from the control response monitoring section 13. Further, if the actual response time is smaller than the upper limit monitoring time of the monitoring time table, a message is output to the control processing section 12 about the actual response time. Monitoring time correction buffer memory 16
is a batza memory that temporarily stores the correction time measured by the correction time measuring section 15. The instruction bit of the addition instruction bit 17 turns on the instruction bit of the designated address by the control program of the control processing unit 12, and addition is valid only for the address that is turned on, and is invalid when it is off. The 7d1 hour of the specified address in the monitoring time correction buffer memory is added to the monitoring time in the monitoring time table in the monitoring time RAM memory 14 of the specified address for which this instruction bit is on. The message output device 18 records and prints the message output data of the actual time of the control response from the control response monitoring section 13 and the actual response time from the correction time measuring section 15.

In FIG. 2, the procedure for instructing the observation master station 4 to control via the interface unit 3 of the processing device if, receiving a control response from the observation master station 4 to the control response monitoring unit 13, and processing the monitoring data is as follows. Since this is the same as the previous description, the description will be omitted, and the method for correcting the monitoring time of the control response monitoring unit 13 will be described. The control response monitoring section 13 has a prescribed monitoring time, for example, t seconds, and if the control response is normally received in a time shorter than t seconds, one normal control response is output to the control processing section 12. Young.

If a control response is received after a period of time that is less than the upper limit monitoring time 'r seconds of the monitoring time table but longer than the specified monitoring time seconds due to some reason, the control response monitoring unit 13 determines the specified monitoring time. After 1 seconds, a monitoring response abnormality signal is sent to the correction time measurement unit 15, and the Pit time measurement unit 15 measures the actual response time r seconds until the control response is received, and the correction value Δt is.

(Δt=r−t) However, L<r is measured as the correction time, and the monitoring time correction buffer memory i
Temporarily stored at the specified address for month 6. Also.

A message is output to the control processing unit 12 about the actual response in r seconds and the specified address. The control processing unit 12 records and prints the actual response time r seconds and the message output of the designated address on the message output device 18.

If the above control instruction-control response is repeated and a large number of message outputs are recorded and printed, and it becomes necessary to correct the monitoring time table at a certain point, the address is specified by the addition instruction focus control program of the control processing section 12. and turns on the instruction bit of the specified address of addition instruction bit I7,
The monitoring time in the monitoring time table for the specified address that is turned on.

t'=10Δt, and the correction time is added. Furthermore, the control response after the monitoring time correction is normal, and the remaining monitoring time is the correction time Δt.
When it is larger than the control response monitoring unit 13, the control processing unit 1
2, the remaining time and designated address are output as a message, and the above correction process is performed to set the monitoring time to an optimal value.

Also, setting the upper limit value for the monitoring time is to prevent the monitoring time from becoming too long due to retries being made due to no control response input within the monitoring time, and to prevent the control response time of the entire system from becoming too long. It is a good idea to set it to an appropriate value.

+g+ In the detailed explanation of the invention), in a processing device for a telemeter/telecontrol system that processes observation data based on a control response from an observation master station that controls a plurality of observation slave stations, the observation master station The control response monitoring unit monitors the control response from the controller, and when no control response is input within two monitoring times, a correction time is measured, and this correction time is determined by the control program of the processing device.

By adopting the configuration of the present invention in which the monitoring time of the control response monitoring section is added to and corrected for the monitoring time of the monitoring time, it is possible to set the monitoring time of the control response monitoring section to an optimal value that suits the actual situation, eliminating unnecessary retries. This has the effect of shortening the processing time of the entire telemeter/telecontrol system without wasting time.
