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°C ~ +70°C.

[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...

Abstract

The environmental zone controller of the present invention sends control signals to actuators such as air-conditioning fans, curtains, lights, and fresh air valves through the collected various signals in the indoor environment, so as to maintain the environmental parameters set by the user. The controller also has digital data and analog input, output interface, RS232, RS485 interface, and RJ45 network interface for data interaction with the host computer; the control software is loaded on the hardware module, and the environmental sensor in the environmental area is controlled through the input port of digital and analog Carry out signal collection, including at least a temperature control module, an optical control module and an air quality control module, and send control signals to air-conditioning fans, curtains, Lighting and fresh air actuators to maintain user-set environmental parameters. Some functions can be enabled according to different regional conditions, such as subsystems such as fresh air volume control system.

Description

technical field [0001] The environmental area controller of the present invention sends control signals to actuators such as air-conditioning fans, curtains, lights, and fresh air valves by collecting various signals in the indoor environment 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 lower controller / all-in-...
