Internet of Things cloud sensor and platform
The IoT cloud sensor is a series of sensors based on cloud platform application technology, intelligent measurement, monitoring technology, clock and environmental parameters (temperature, humidity, location, etc.). It is not only featured in wireless transmission, but also has unique remote management functions such as data measurement, threshold setting, clock synchronization, measurement time setting, acquisition cycle setting, alarm setting, interference detection, software update and so on. The product is upgraded from a single measurement to the function of measurement, monitoring, judgment and alarm. It is very suitable for measurement, monitoring and state judgment in the industrial field.
The main functions of the system:
1 Signal Acquisition: Support current, voltage, power, frequency, active power, reactive power, temperature, capacitance, lightning strike parameters, etc.
2 State Judgment: It can flexibly judge the normal, abnormal, damaged and other states of the monitored points.
3 Networking mode: Flexible and convenient combination of wireless and wired methods for system monitoring units.
4 Remote duplex: Two-way communication and setting management functions among the sensor and the cloud platform and the user system. For details, see the “Duplex” function table.
5 Self-diagnosis: The intelligent series of sensors can be used to monitor the interference of power, input, output, and key points in its own.
6 Transmission mode: wireless transmission with GPRS, NB-IOT, LORA, 4G, 5G, etc., and multiple wired and wireless conversion modes.
7 Alarm service: alarms for the abnormality and damage of the device through APP, WeChat, webpage, SMS, etc.
8 Data Services: Provide following services according to Big Data on Cloud Platform:
1) Equipment status service: services about normal, deterioration, interference, error, alarm, etc.
2) Equipment quality service: using interference, error and alarm data to provide users with product quality and performance analysis data. 3) Equipment maintenance service: time, location, and self-diagnosis data provide users with accurate and timely maintenance information.
4) Data analysis services: functional model analysis services such as numbers, trend graphs, and limit condition query.
5) Model data service: use the time period, mean value, typical value and error value in the remote “duplex” to establish various equipment state model data, convenient for customers to analyze and judge.
6) Error diagnosis service: use synchronous clock, error data, intelligent products, model data, etc. in remote "duplex" to provide multi-point data and multi-product data at error time to accurately restore error status for diagnostic purposes.
7) Big Data Services: Analysis of the above big data (data, modeling, judgment).
