Central air conditioner temperature controller cost control method and system based on LORA communication

Abstract

The invention provides a central air conditioner temperature controller cost control method based on LORA communication. A temperature controller is provided with a communication module. The method comprises the following steps that the temperature controller is in communication connection with a gateway with the communication module; the gateway is in communication connection with a cloud serverand is provided with an upper computer capable of calling a third-party payment interface to be connected to the cloud server; the upper computer sends payment amount data to the temperature controller through the cloud server and the gateway; and the temperature controller is used for recording the accumulative use time of an air conditioner fan or the two-way valve, and stopping using the temperature controller when the accumulated use time corresponds to the use amount until the balance reaches a set value. The invention further provides a central air conditioner temperature controller costcontrol system based on communication. According to the temperature controller, wiring can be avoided, the complicated scheme that a traditional user is charged by an IC card is avoided, the cost isconveniently paid by calling the third-party payment platform interface, the charge amount is recorded in the temperature controller, and a central air conditioner can normally operate.

Description

technical field [0001] The invention relates to the field of central air-conditioning control systems, in particular to a method and system for controlling the cost of a central air-conditioning thermostat based on LORA communication. Background technique [0002] The central air-conditioning billing system mainly has two billing methods: energy-based and time-based. Energy-based billing is measured by installing ultrasonic or electromagnetic cooling meters at the end of each air conditioner. However, in actual projects, ultrasonic heat meters are used to take the negative method to replace the cold meter, the heat measurement is usually small flow and large temperature difference, and the cold measurement is usually large flow and small temperature difference, which requires high temperature measurement. The traditional ultrasonic heat meter used for heating measurement is not suitable for use in air conditioning. However, the special air-conditioning cold meter is expensiv...
