Description

[Detailed Description of the Invention] [Summary] As in a water level and rainfall telemeter system for river management, a master station sequentially calls multiple slave stations at predetermined time intervals, causes them to transmit data, and transmits the data. In a telemeter system that processes and displays data at the master station, important data can be processed and displayed each time data is received from each slave station, without having to wait for data collection from all slave stations. This makes it possible to quickly respond to specific data.

[Industrial application field]

The present invention is similar to a water level/rainfall telemeter system for river management, etc., in which a master station sequentially calls multiple slave stations at predetermined time intervals, causes them to transmit data, and processes this data at the master station. This invention relates to an improvement in a received data processing method for a telemeter system that displays images.

The following is an explanation using a water level and rainfall telemeter system for river management as an example.

FIG. 2 is a block diagram of an example water level and rainfall telemeter system.

In the figure, 1 is an operator console, 2 is a processing device, 3 is a wireless device, 4 is a display device, 5 is a printer, 10 is a master station, and 11 to 13 are slave stations.

The slave stations 11 to 13 that observe rainfall or water levels are generally located in remote mountains and use solar cells as power sources, so the observation time from the master station 10 is less important than the power capacity. Since it is better to have as long an interval as possible, considering this point, the master station 10 sets the data collection time interval to 10 minutes, 1 hour, etc. depending on whether it is heavy rain, rainy, sunny, etc. 3 hours, 1
An instruction to change the interval to 2 hours, etc. is given from the console 1, and at this time interval, the processing device 2. The slave stations 10 to 13 are sequentially called via the radio 3, and each slave station 10 to 13 sequentially transmits observation data.This data is received by the radio 3, processed by the processing device 2, and the water level is , rainfall amount, basin average rainfall amount, prediction of dam inflow amount, etc. are displayed on the display device 4 and printed on the printer 5.

In this case, for example, data from a slave station that observes water levels in places where rivers are likely to burst during heavy rains, or data from slave stations that cover a wide basin, must wait until all data is collected. It is hoped that this will be displayed as soon as possible, and that a response can be taken as soon as possible.

[Conventional technology]

As shown in FIG. 3, the conventional received data processing method is to sequentially call each slave station 11 to 13 from the master station 10 in FIG. , In the processing device 2 shown in Fig. 2, water level data, rainfall data, etc., are processed to convert the count value into data in mm units, and the basin average rainfall is calculated from each rainfall data, and the rainfall data and water level data are processed. Calculations are made to predict the amount of inflow into the dam, and the water level is calculated.

Rainfall, average rainfall in the basin, predicted values of dam inflow, etc. are displayed on the display device 4 shown in FIG. 2 and printed on the printer 5.

[Problem that the invention seeks to solve]

However, in this conventional method, data is displayed after collecting data from all slave stations, so for example, if it takes 6 seconds to collect data for each station and there are 50 slave stations,
The data will be displayed 300 seconds after data collection starts. For example, during heavy rain, even if the data collection time interval is 10 minutes, data from a slave station observing the water level in a place where a river is likely to burst, etc. There is a problem in that it is slow to display important data, such as data from slave stations that observe rainfall over a wide basin, which should be immediately processed and displayed, so that a quick response can be taken.

Means for Solving Problem c] The above problem is solved by the received data processing method of the present invention, which processes and displays what can be processed every time data is received from each slave station. Ru.

[Effect]

According to the present invention, each time data is received from each slave station,
What can be processed is processed and displayed, so there is no need to obtain and process multiple data, such as water level or rainfall, and what can be processed is displayed at the same time as data is received. Therefore, data from a slave station that is observing the water level in a place where a river is likely to burst, or data from a slave station that is observing rainfall in a wide basin area, is displayed at the same time as the data is received. It is possible to respond quickly to this problem.

〔Example〕

In the case of the present invention, a program for performing the processing shown in the flowchart of processing shown in FIG. 1 is provided in advance to the processing device 2 shown in FIG.

Therefore, each time the master station 10 in FIG. 2 receives data from each of the slave stations 11 to 13 via the radio 3, the processing device 2 converts the received water level and rainfall count value into data in mm units. It is processed and displayed on the display device 4, and all slave stations 11 to 1
Once we have collected the data from step 3, we will calculate the basin average rainfall from each rainfall data, and we will calculate the prediction of dam inflow from the rainfall data and water level data, etc., and process things that cannot be processed without multiple data. Then, the average rainfall in the basin, the predicted value of the dam inflow, etc. are displayed on the display device 4 and are printed on the printer 5. At this time, the printer 5 also prints the rainfall amount and water level.

Therefore, data from a slave station observing the water level in a place where a river is likely to burst, or data from a slave station observing rainfall over a wide basin, is displayed at the same time as the data is received. It is possible to respond quickly.

It goes without saying that the order in which data is collected should be early (starting with the slave station observing the data to be displayed).

〔Effect of the invention〕

As explained in detail above, according to the present invention, each time data is received from each slave station, the data that can be processed is immediately processed and displayed. It has the effect of making it faster.
