Technology module configuration.

Number	Module name	Module Content and Functions
1	Data acquisition	Monitoring of the airconditioning system, including line temperature, pressure, mainframe operating parameters, thermostat setting parameters, power consumption, temperature of the least favourable end line, and temperature and humidity of part of the room;
2	Heating and cooling source control	Communicate with the host to enable remote monitoring and control by the host.
3	Frequency conversion optimisation	Configure variable frequency optimisation for circulating pumps, according to temperature, pressure, temperature difference, differential pressure and other parameters, to achieve self-regulation of the pump frequency, to achieve the flow rate to matches the end demand.
4	Intelligent Algorithm Statistics	Implant intelligent control logic rules to achieve schedule control, optimisation control and energy-saving control functions; the control strategy is based on expert rules collected from big data, including: load prediction, equipment optimisation, water temperature control, pressure control, adding and subtracting machine control, multi-pump operation and so on.
5	System Alarms	Access to alarm messages from the host computer; preset alarm information for the main operating parameters of the system. Provide alarm rule setting function; Provide alarm information SMS, voice push.
6	AIOT platform	Configure visualisation WEB side platform and APP application; Provide data professional data analysis tools; Historical records, energy consumption data export.
