Description

Facility Measurement Data Wireless Transmission System {RF TRANSMITTER SYSTEM OF INSTRUMENTATION DATA}

The present invention relates to a wireless transmission system for facility measurement data that can be used at a measuring point having an address of 60 to 100 in an area, for example, 30 to 500 m intervals, and more specifically, each measuring point in a measuring area in a small area. The present invention relates to a facility measurement data wireless transmission system capable of sequentially mapping the corresponding measurement point data according to the shortest distance between the small output radio waves and transmitting the final data collection and control device.

In general, as underground facilities, water pipes, sewage pipes, rainwater pipes, power lines, communication lines, and gas pipelines are buried within a certain depth so that various means can be connected or connected from one area to the next. It extends to the distance through the connection point or connection point with the back.

The water supply pipe of the underground facilities is connected to the main building to the corresponding distance and the final building or house through the pipe of each necessary branch or classification from the main road to smoothly supply or drain the raw water from the water supply. By the way, the water transportation in the main pipeline buried underground can be checked by the naked eye or other methods by the surrounding land wet or gushing to the ground when leaking under high pressure. This makes it difficult to detect leaks in the connection area.

In order to detect the leak, a pressure sensor or a flow detector is installed at the connection part when replacing a new pipe or pipe, and when it is leaked, it is checked and notified to the monitoring equipment of the ground or other points to take further measures. Since such leak check is an underground facility, there was a limit in finding the correct distance or point. Therefore, we used to approach the nearest point by various methods or means to check for leaks and points of underground facilities.

Applicant installed the auxiliary jacket to check the pressure sensor or the flow rate detector at each connection part of the pipeline for accurate leak check, and systemized to be notified of abnormal symptoms more easily and accurately by connecting wired and wireless to the point connected to the ground. It is developing variously to systematize facility measurement. Therefore, hydraulic pressure or flow rate data is transmitted from the water supply pipe of the underground facility to each of the points connected thereto, and it can be connected to the ground using the wired or wireless connection.

The present invention has been invented so that check data of water pipes of underground facilities can be usefully connected from the ground to the Internet in view of the above circumstances. Since the data of the measuring point single measuring terminal are sequentially mapped and transmitted to the final data collection and control device according to the shortest distance of the small output radio wave between the measuring point single measuring terminals, the periodic collection of generated data is received and the data is received at a specific measuring terminal. Its purpose is to provide a facility measurement data wireless transmission system that can give specific commands and give simultaneous commands to the whole.
