Embodiment Construction

[0023] The hardware system has a permanent storage space of 128k, has an Ethernet interface, and can communicate with the outside world. It has 16 digital input channels, 8 digital output channels, 8 analog input channels and 3 analog output channels, all of which have photoelectric isolation. It has RS-232 and RS-485 interfaces, internal clock, and its operating temperature is -40℃~+70℃.

[0024] Because it has digital and analog input and output I / O interfaces at the same time, it can quickly and conveniently control the environmental sensors and control modules of the terminal. The appearance of the hardware is as attached figure 1 The main view of the external structure of the hardware, the attached figure 2 Rear view of hardware structure and attached image 3 The outline structure of the hardware is shown in the top view. figure 1 Among them, AO0~AO2 are analog output terminals, 5M is a common terminal, AI0~AI7 are analog input terminals, I0~I15 are digital input ter...

Abstract

The invention relates to an environment zone controller which is used for controlling signals to be sent to executing mechanisms of an air conditioner fan, a curtain, a lamp, a new wind valve and the like through various acquired signals in an indoor environment so as to maintain environment parameters set by a user. The controller is also provided with an input port and an output port of digital quantity and simulating quantity, an RS232 port, an RS485 port, and an RJ45 port carrying out data interaction with an upper computer; and control software is loaded on a hardware module, carries out signal acquisition on an environment sensor in the environment zone through the input port of digital quantity and simulating quantity, at least comprises a temperature control module, an optical control module and an air quality control module, and controls the signals to be sent to the executing mechanisms of the air conditioner fan, the curtain, the lamp, the new wind valve and the like by the temperature control module, the optical control module and the air quality control module according to various acquired signals so as to maintain the environment parameters set by the user. The invention can start one part of functions according to different zones, such as subsystems of a new wind quantity control system and the like.

Description

Technical field [0001] The environmental area controller of the present invention, through collecting various signals in the indoor environment, control signals are sent to the actuators such as air-conditioning fans, curtains, lights, and fresh air valves, so as to maintain the environmental parameters set by the user. Some functions can be enabled according to different regional conditions, such as lighting and curtain control systems in light environments, fresh air volume control systems, temperature control systems and other subsystems. Background technique [0002] The currently known environmental controllers have the following characteristics: 1. RS485 communication mode; 2. There are three RS485 buses, and each RS485 bus can be connected to at least 24 access controllers / integrated machines; 3. Through three RS485 buses, it can greatly The expansion system can accommodate the number of control nodes; 4. The regional controller collects the monitoring data of the low...
