Background of the programme

In recent years, the summer temperature is getting higher and higher has become an irreversible trend, fortunately, as early as 100 years ago, there was an American known as the "father of air conditioning": Willis Havilland Carlil has invented air conditioning, after more than 100 years of development, the current air conditioning technology has been quite mature, it can be described as cheap and good, air conditioning has also become an ordinary household appliance into people's production and life.

Air conditioners can be divided into two main categories: ordinary air conditioners and central air conditioners, of which central air conditioners are mostly used in large public places, and ordinary air conditioners are suitable for independent rooms or households. Due to the low price, easy installation and maintenance of ordinary air conditioners and many other advantages, the utilization rate of ordinary air conditioners accounts for about 70% of all air conditioners, but due to the lack of remote communication modules of ordinary air conditioners, resulting in air conditioners can not achieve remote centralized management, the unreasonable and unscientific use of air conditioners leads to great waste, which has also become a "headache" management problem.

Overview of the scenario

Different from high-end central air conditioning or precision air conditioning, most of the air conditioners on the market are equipped with standard air conditioning remote control, and the default configuration of the air conditioning control panel does not contain a remote communication module, so it provides remote monitoring function. In response to this situation, our company as early as 15 years ago proposed by using the deployment of auxiliary air conditioning controller on the air conditioner to achieve the remote monitoring and management function of the air conditioner, after more than 10 years of iteration, at present, our company has successfully developed the third generation of air conditioning controller products: wireless air conditioning controller, this product perfectly solves the problem of difficult field wiring, so that the centralized management of air conditioning becomes simple, convenient and easy to implement, this program will not damage any function of the air conditioning itself, mainly to achieve the following functions:

1. Air conditioner ambient temperature and humidity monitoring and alarm function;

2. Real-time monitoring function of air conditioning operation status;

3. Air conditioner call self-start function;

4. Automatic energy-saving control function of air conditioner;

5. Detection function of air conditioning operation status and equipment fault state;

6. Air conditioner remote power on/off, temperature setting, mode setting and other functions.

Schematic design

Zonghengtong air conditioning wireless centralized management solution is a set of efficient, stable and cost-effective air conditioning management system that integrates air conditioning infrared technology, wireless communication and data centralized processing technology. The overall system architecture diagram is as follows:

Program features:

The scheme follows the principles of simple commissioning, convenient construction and cost saving, and makes the project construction simple and convenient by making the debugging tool mobile phone terminal and the built-in infrared code of the air conditioner factory. It has the following characteristics:

1. Adopt the international standard 433MHZ communication frequency band, low power consumption and communication quality are guaranteed;

2. Built-in common infrared code library, which effectively solves the problem of difficult code learning for on-site air conditioning controllers;

3. The direct debugging function of the mobile phone makes it easy to access the air conditioning controller;

4. Air conditioning controller, mature technology, good compatibility, stable and reliable overall operation;

5. The construction period of the system is short, and there is less human interference;

6. Wireless networking, concise and practical overall architecture;

7. Linkage control, no need for manual operation and management;

8. Mature solution, practical overall function.
