Internet of Things environment control method and device based on context-aware

Abstract

The invention discloses an Internet of Things environment control method and device based on context-aware. The method comprises the following steps: an environment control device in a network collects context-aware data to judge whether people are in a controlled zone or not; if people are in the controlled zone, the environment control device ensures that an intervalometer resets to a set time, humiture is processed by treating forecast average vote numbers as a PMV value, and then correspondence of the data is performed according to a set value table, a comfort degree mapping table and a control rule mapping table to obtain a control strategy of a controlled terminal; if people are not in the controlled zone, the environment control device detects whether a working controlled terminal exists or not, if no, no operation is carried out; if yes, the turning on or the turning off of the intervalometer is judged, if the intervalometer is turned off, the turning on of the intervalometer is performed, and when the intervalometer returns to zero, a control command is transmitted to close the working controlled terminal, if the intervalometer is turned on, countdown is performed continuously until the intervalometer returns to zero, or the controlled zone is detected again to ensure that whether people are in or not. The method and the device, provided by the invention, can realize intelligently real-time control of the controlled terminal to adjust the environment so as to meet comfort degree requirements of users.

Description

technical field [0001] The present invention relates to the technical field of network control, in particular to a method and device for environment control of the Internet of Things based on context awareness. Background technique [0002] With the improvement of people's requirements for quality of life and service quality, wireless sensor networks have been widely used in smart buildings, smart homes, industrial control and other fields. The monitoring network is composed of a large number of micro-sensor nodes and controlled terminals deployed in the controlled area, and performs data exchange and controls the controlled terminal through wireless communication. Due to the uncertainty of human senses, the complexity of environmental requirements and the continuous improvement of the demand for environmental comfort, improving the intelligence of indoor environmental control has become an indispensable and important technology in the field of control in recent years.

Problems solved by technology

[0003] In the existing technology, the automatic control method of the controlled terminal in the monitoring network is to calculate the deviation between the environmental parameters and the user's set value through the controller, and then output the control amount according to the size of the deviation pair, so as to realize the adjustment of the controlled terminal , however, this method needs to modify the existing controlled terminal hardware, which increases the cost and difficulty of implementation, and is not suitable for the environment control mode of most existing users

[0004] In the process of realizing the embodiment of the present invention, the inventor found that in the prior art, the controlled terminal is controlled by the control device, and only the environmental impact parameter of a single device is corrected, because the indoor environment is the joint action of multiple environmental control devices As a result, this may cause terminal equipment related to the same environmental parameter to work at the same time, thereby increasing power consumption
