IoT Method for Controlling Biosafety Cabinet Combined via Internet of Things

摘要

A method for controlling a bio-safe work bench by the Internet according to the present invention includes a power controller, a wind speed controller, a temperature sensor, a filter check sensor, a filter life sensor, a UV lamp controller, a pressure sensor, a wind speed sensor, a door position sensor, And an external communication unit connected to each of them to receive a sensor input or transmit a control output and to be connected to an external communication network. A communication start step; A data presence / absence detection step of detecting presence / absence of data received from a server; Initiating data reception by the sensor node when data is detected; Receiving data; Changing received data to data suitable for control of the controllers; Controlling the control units using the changed data; Inputting sensor data when data is not detected in the data presence / absence detection step; Transmitting the sensor data to a sensor node; Transmitting the sensor data from a sensor node to a repeater; Checking whether there is an abnormality in the transmitted data; Transmitting the data from the repeater to the server when the data is abnormal; And storing the data in a database of the server.
