Description

Measurement And Data Collecting Integrated Apparatus

The present invention belongs to the technical field of a device for receiving and collecting data from a sensor and measuring an environmental pollution emission.

Currently, industries that preserve the environment and industries that can grow while protecting the environment are in the spotlight. In other words, the low-carbon green industry is growing. In particular, the low-carbon green industry is being led by advanced countries in the world and is expected to further revive in the future.

Korea is also participating in the green industry along with the world's advanced countries. Accordingly, the government is looking for ways to reduce greenhouse gas emissions and reduce energy use by increasing energy use efficiency.

As part of the above-mentioned measures, the government is supporting the installation of facilities suitable for the low-carbon green industry in newly built buildings, factories, or apartment houses such as apartments. In addition, we are looking for ways to increase energy consumption efficiency more efficiently by collecting data output from facilities through various sensors. In addition, the government is actively supporting the business of data collectors that measure and collect data.

Currently, many data collectors developed and used for such government support are mainly devices whose input methods are limited to analog (4-20mA, voltage) and digital (RS232, RS485) inputs. Here, the digital input has a problem in that it is difficult to match the protocol because the protocol between the sensor and the transducer manufacturer is different, and accordingly, the use of the sensor and the transducer is restricted. In addition, additional devices such as temperature sensors, magnetic switch contact detection, signal converters, and digital ammeters are required to monitor the operation status of environmental emission facilities and prevention facilities in the data collector. These additional devices complicate the construction of the equipment and increase the cost of the construction of the equipment.

That is, the conventional data collector causes various problems in building a system for collecting data.
