Structure. The digital platform consists of cloud servers (Private CloudorPublic Cloud)DAQ for IIOT scadaGeneral Industrial Data Acquisition System Software Composition; The communication network consists of IoT gateway, wireless communication terminals, local area network, and the Internet; Signal data acquisition is carried out by a wireless acquisition moduleSC-GP-EM4GIt consists of wireless power monitoring instruments, wireless intelligent Sensor, and so on.

The project implementation is simpler and more convenient, with lower construction costs and a shorter construction period for daq iot data acquisition IoT. Whether it is adding monitoring equipment to existing production equipment or adding Data Acquisition to new lines, project implementation is very simple, convenient, and economical. Choose wireless communication to transmit data, and for monitoring points with inconvenient power supply, choose battery powered Sensor and collectors to avoid the troubles caused by cable laying; Electricity consumption Data Acquisition, choose a multi circuit power monitoring meter, and equip it with RS485 open type current transformers to avoid disassembling cables and copper bars in the original distribution cabinet, and to not increase the design and production difficulty of the new distribution cabinet, greatly reducing construction costs and construction period; Signal acquisition or data reading, if there are already monitoring points on the original equipment, signals can be collected from the original Sensor or data can be read from the collector to reduce construction costs and difficulties, without causing any impact on the original system.
