[0022] The following will be described in detail in combination with the accompanying Figure 1 The utility model will be described in further detail, but not as the limitation of the utility model.

[0023] The application provides a multi-group air conditioner control system, which comprises a centralized controller and an extension 2, the extension 2 is electrically connected with the centralized controller; the extension 2 is further externally connected with an intelligent environment sensing assembly, and the intelligent environment sensing assembly is electrically connected with the extension 2; the centralized controller and the extension 2 are both provided with a remote control and upgrading module 4.

[0024] The electrical connection between the centralized controller and the extension 2 can be realized in various ways, such as wired connection or wireless connection. The intelligent environment sensing assembly can include various sensors, such as temperature sensor 31, humidity sensor 32, carbon monoxide sensor 33, carbon dioxide sensor 34 and PM2.5 sensor 35, which are connected with the extension 2 for real-time monitoring of environmental parameters. The remote control and upgrading module 4 can be built-in with a 4G / 5G unit 41, and the centralized controller and the extension 2 are connected through the 4G / 5G unit 41 to realize networking, thereby realizing remote control and system upgrading.

[0025] The technical scheme realizes accurate, efficient and intelligent control of the air conditioner system through the electrical connection of the centralized controller and the extension 2, and the setting of the intelligent environment sensing assembly. The remote control and upgrading module 4 in the centralized controller and the extension 2 enables the system to be remotely controlled and upgraded through the network, improving the flexibility and maintainability of the system. The intelligent environment sensing assembly can monitor environmental parameters in real time and adjust the operating state of the air conditioner system according to the monitoring results, thereby realizing more accurate environmental control.

[0026] Compared with the prior art, the technical scheme solves the technical problem that the traditional air conditioner control system is difficult to realize accurate, efficient and intelligent control in large places through the cooperative work of the centralized controller and the extension 2, and the introduction of the intelligent environment sensing assembly. The scheme not only improves the control accuracy and efficiency of the air conditioner system, but also enhances the intelligent level of the system, so that the system can better adapt to complex and variable environmental demands.

[0027] Furthermore, this application also proposes that there is one central controller and at least 32 extension units 2, all of which are connected to the central controller.

[0028] Specifically, the central controller, as the core control unit of the system, is responsible for coordinating and managing the operation of all Sub-Units 2. Sub-Units 2, as execution units, are responsible for specific environmental control and data acquisition tasks. By setting up at least 32 Sub-Units 2, the system can cover a larger spatial range and achieve independent control of multiple areas. The connection between each Sub-Unit 2 and the central controller ensures real-time data transmission and rapid command execution.

[0029] As a preferred implementation, the connection between extension unit 2 and the central controller can be achieved through wired or wireless communication protocols, such as the RS485 communication protocol. This connection method not only ensures the stability and reliability of data transmission, but also effectively reduces the complexity and cost of the system.

[0030] Therefore, the technical solution of this application achieves precise, efficient, and intelligent control of large venues by setting up a centralized controller and multiple sub-units 2. Compared with existing technologies, this solution can significantly improve the system's scalability and flexibility, while reducing system maintenance costs and energy consumption. Through the collaborative work of the centralized controller and sub-units 2, the system can monitor and adjust the environmental parameters of each area in real time, thereby providing a more comfortable and healthy environment.

[0031] Furthermore, this application proposes that extension unit 2 communicates with the host via the RS485 communication protocol. The RS485 communication protocol is a standard for serial communication, supporting multi-point communication and enabling reliable data transmission over long distances. Specifically, the RS485 communication protocol uses differential signal transmission, which has strong anti-interference capabilities and is suitable for long-distance communication in industrial environments. As a preferred implementation, communication between extension unit 2 and the host can be achieved via twisted-pair cable, which effectively reduces electromagnetic interference and improves communication stability. In addition, the RS485 communication protocol supports multi-device connection, enabling multiple extension units 2 to exchange data efficiently with the host.

[0032] Therefore, this application solves the technical problem of traditional air conditioning control systems struggling to achieve precise, efficient, and intelligent control in large venues by adopting the RS485 communication protocol. Specifically, the high anti-interference capability and long-distance transmission characteristics of the RS485 communication protocol make the communication between Sub-unit 2 and the host more stable and reliable, thereby improving the control accuracy and response speed of the entire system. Furthermore, since RS485 supports multi-point communication, multiple Sub-units 2 can exchange data with the host simultaneously, avoiding the inaccurate control problems caused by communication delays or interruptions in traditional systems. Compared with existing technologies, the technical solution of this application has significant advantages in communication efficiency and stability, and can better meet the high-efficiency control requirements of air conditioning systems in large venues.

[0033] Furthermore, this application proposes that the number of intelligent environmental sensing components corresponds to the number of extension units 2, and each intelligent environmental sensing component is connected to its corresponding extension unit 2. The intelligent environmental sensing components include a temperature sensor 31, a humidity sensor 32, a carbon monoxide sensor 33, a carbon dioxide sensor 34, and a PM2.5 sensor 35 arranged sequentially, all of which are connected to the extension unit 2.

[0034] Specifically, the number of intelligent environmental sensing components corresponds to the number of sub-units 2, meaning that each sub-unit 2 is equipped with an independent intelligent environmental sensing component, ensuring that each sub-unit 2 can independently perceive the state of its environment. This design allows the system to more accurately monitor and control the environmental parameters of the area where each sub-unit 2 is located. For example, temperature sensor 31 is used to detect ambient temperature, humidity sensor 32 is used to detect ambient humidity, carbon monoxide sensor 33 and carbon dioxide sensor 34 are used to detect air quality, and PM2.5 sensor 35 is used to detect the concentration of particulate matter in the air. These sensors exchange data with the central controller through sub-units 2, thereby achieving intelligent management of the entire system.

[0035] In a preferred embodiment, the intelligent environmental sensing component can be connected to unit 2 via wired or wireless means. Wired connections can utilize the RS485 communication protocol to ensure stable and reliable data transmission; wireless connections can employ Bluetooth or Wi-Fi technology for ease of installation and maintenance. Furthermore, the intelligent environmental sensing component can be equipped with self-diagnostic functions, enabling real-time monitoring of the sensor's operating status and automatic alarms in case of malfunctions, thereby improving system reliability and maintenance efficiency.

[0036] Therefore, the technical solution of this application achieves precise monitoring and control of the environment in which each sub-unit 2 is located by connecting the intelligent environmental sensing component to the sub-unit 2 in a one-to-one correspondence. Compared with the prior art, this solution not only improves the intelligence level of the system, but also enhances the reliability and maintainability of the system, thereby effectively solving the technical problem that traditional air conditioning control systems are difficult to achieve precise, efficient and intelligent control in large venues.

[0037] Furthermore, this application also proposes that the intelligent environmental sensing component includes a temperature sensor 31, a humidity sensor 32, a carbon monoxide sensor 33, a carbon dioxide sensor 34, and a PM2.5 sensor 35 arranged sequentially, all of which are connected to the sub-unit 2.

[0038] Specifically, temperature sensor 31 is used to detect ambient temperature, humidity sensor 32 is used to detect ambient humidity, carbon monoxide sensor 33 is used to detect the concentration of carbon monoxide in the environment, carbon dioxide sensor 34 is used to detect the concentration of carbon dioxide in the environment, and PM2.5 sensor 35 is used to detect the concentration of PM2.5 particles in the air. These sensors transmit the detected data to the central controller through sub-unit 2, and the central controller uses this data to precisely control the air conditioning system.

[0039] As a preferred embodiment, the temperature sensor 31 can be a digital temperature sensor, such as DS18B20, which has high accuracy and stability; the humidity sensor 32 can be a capacitive humidity sensor, such as HI H-4000, which has fast response and high accuracy; the carbon monoxide sensor 33 can be an electrochemical sensor, such as MQ-7, which has high sensitivity and long lifespan; the carbon dioxide sensor 34 can be an infrared sensor, such as MH-Z19B, which has a wide measurement range and good stability; and the PM2.5 sensor 35 can be a laser scattering sensor, such as GP2Y1010AU0F, which can monitor the concentration of particulate matter in the air in real time.

[0040] Therefore, by setting up multiple sensors, this application can comprehensively and accurately perceive environmental parameters, thereby achieving intelligent control of the air conditioning system. Compared with existing technologies, the technical solution of this application can more precisely adjust the working state of the air conditioning system, improve the system's energy efficiency ratio, reduce energy waste, and enhance the user experience.

[0041] Furthermore, this application also proposes that the remote control and upgrade module 4 has a built-in 4G / 5G unit 41, and the central controller and the extension unit 2 are connected to the network through the 4G / 5G unit 41.

[0042] Specifically, the 4G / 5G unit 41 is a wireless communication module capable of supporting high-speed data transmission and low-latency communication. Through the built-in 4G / 5G unit 41, the central controller and the extension unit 2 can achieve remote control and software upgrades. The 4G / 5G unit 41 can connect to the mobile network via a SIM card or eSIM card, thereby enabling communication with external servers. Furthermore, the 4G / 5G unit 41 can also support multiple network protocols, such as TCP / IP and MQTT, to ensure the stability and security of data transmission. As a preferred implementation, the 4G / 5G unit 41 can also support dual-SIM dual-standby functionality to enhance network reliability.

[0043] Therefore, the technical solution of this application, through the built-in 4G / 5G unit 41, enables the centralized controller and the sub-unit 2 to achieve remote control and upgrades, solving the technical problem that traditional air conditioning control systems are difficult to achieve precise, efficient, and intelligent control in large venues. Compared with the prior art, the technical solution of this application has higher communication efficiency and stronger network stability, which can effectively improve the control accuracy and response speed of the system.

[0044] Furthermore, this application also proposes that a redundant module 6 is provided in the central controller. The redundant module 6 is a lithium battery. One end of the redundant module 6 is connected to an external power supply, and the other end is connected to the central controller and the sub-unit 2 respectively.

[0045] Specifically, the redundancy module 6 is introduced to provide backup power to the central controller and sub-unit 2 via lithium batteries when the external power supply fails or is interrupted, thereby ensuring the continuous operation of the system. Lithium batteries, as a common energy storage device, are characterized by high energy density, long lifespan, and rapid charging and discharging, making them suitable for use as redundant power sources. One end of the redundancy module 6 is connected to the external power supply via a power interface, and the other end is connected to the central controller and sub-unit 2 via a power distribution circuit, ensuring a seamless switch to lithium battery power in the event of an external power outage.

[0046] In a preferred embodiment, the redundant module 6 may also be equipped with a power management unit to monitor the status of the external power supply and the lithium battery charge, and automatically switch power supplies as needed. Furthermore, the capacity of the lithium battery can be configured according to the system's power consumption requirements to ensure sufficient backup power support when the external power supply is interrupted.

[0047] Therefore, this application solves the technical problem of traditional air conditioning control systems being unable to operate continuously during external power failures by introducing redundant module 6. This technical solution not only improves system reliability but also avoids control failures caused by power interruptions, thus achieving more stable and efficient air conditioning control. Compared with existing technologies, the technical solution of this application has significant advantages in power management, effectively responding to sudden power failures and ensuring continuous system operation.

[0048] Furthermore, this application proposes that a control module 11 be installed within the central controller, and the control module 11 be electrically connected to the extension unit 2. The control module 11 is used to receive and process data from the extension unit 2, and send control commands to the extension unit 2 according to preset control logic to achieve precise control of the extension unit 2. The control module 11 can be implemented in various ways, such as using a microprocessor or programmable logic controller (PLC) as the core processing unit, combined with corresponding software algorithms to achieve control of the extension unit 2. Specifically, the control module 11 can communicate with the extension unit 2 via the RS485 communication protocol to ensure the stability and real-time performance of data transmission.

[0049] The introduction of control module 11 enables the central controller to manage multiple sub-units 2 more flexibly. Especially in large venues, it can dynamically adjust the operating status of sub-units 2 based on data collected by environmental sensing components, thereby achieving more precise and efficient air conditioning control. For example, when temperature sensor 31 detects that the temperature in a certain area is too high, control module 11 can immediately send a command to the sub-unit 2 in that area to adjust the air conditioning operating parameters to achieve a rapid cooling effect.

[0050] By incorporating the control module 11, the technical solution of this application effectively addresses the technical problem of traditional air conditioning control systems struggling to achieve precise, efficient, and intelligent control in large venues. Compared with existing technologies, this application, through the introduction of the control module 11, not only improves the system's response speed and control accuracy but also enhances its scalability and flexibility, enabling the air conditioning system to better adapt to complex and ever-changing environmental demands.

[0051] Furthermore, this application also proposes that the central controller is equipped with an instruction module 12, which is electrically connected to the control module 11.

[0052] The main function of instruction module 12 is to receive and process instructions from control module 11, thereby controlling extension unit 2. Instruction module 12 can be implemented in various ways. For example, it can be a microprocessor unit responsible for parsing the instructions sent by control module 11 and sending the parsed instructions to extension unit 2. Instruction module 12 can also be a logic circuit that processes the instructions from control module 11 through logical operations and transmits the processing results to extension unit 2. Furthermore, instruction module 12 can also be a software module running on the central controller's operating system, processing the instructions from control module 11 through software algorithms.

[0053] Specifically, the instruction module 12 works as follows: When the control module 11 receives an externally input control instruction, it sends the instruction to the instruction module 12. Upon receiving the instruction, the instruction module 12 parses and processes it according to preset logic or algorithms, generating corresponding control signals. These control signals are then sent to the extension unit 2, which performs corresponding operations based on the received control signals, such as adjusting the air conditioner's temperature and humidity parameters.

[0054] By setting the instruction module 12, the technical solution of this application can achieve precise control of the sub-unit 2, solving the technical problem that traditional air conditioning control systems are difficult to achieve precise, efficient, and intelligent control in large venues. Compared with the prior art, the technical solution of this application has higher control accuracy and response speed, and can better meet the air conditioning control needs of large venues.

[0055] Furthermore, this application also proposes that an alarm monitoring module 13 is provided in the central controller, and the alarm monitoring module 13 is electrically connected to the instruction module 12.

[0056] The main function of the alarm monitoring module 13 is to monitor abnormal conditions in the system in real time and trigger an alarm when an abnormality is detected. Specifically, the alarm monitoring module 13 can receive control signals from the command module 12 through an electrical connection and monitor various components in the system based on these signals. For example, when the temperature sensor 31 in the system detects an abnormal temperature, the alarm monitoring module 13 can receive this information and send an alarm signal to the central controller through the command module 12, thereby triggering the corresponding alarm mechanism.

[0057] In a preferred embodiment, the alarm monitoring module 13 may include multiple sensor interfaces for connecting different types of sensors, such as a temperature sensor 31, a humidity sensor 32, a carbon monoxide sensor 33, a carbon dioxide sensor 34, and a PM2.5 sensor 35. Through these sensors, the alarm monitoring module 13 can acquire environmental data in real time and determine whether any abnormalities exist based on preset thresholds. Furthermore, the alarm monitoring module 13 can also be connected to the remote control and upgrade module 4, enabling alarm information to be transmitted to a remote control center in real time via a 4G / 5G network, thereby achieving remote monitoring and alarm functions.

[0058] The technical solution of this application, by introducing an alarm monitoring module 13, effectively solves the technical problem that traditional air conditioning control systems struggle to achieve precise, efficient, and intelligent control in large venues. Specifically, the alarm monitoring module 13 can monitor abnormal conditions in the system in real time and, through collaboration with the command module 12, promptly trigger the alarm mechanism, thereby improving the system's safety and reliability. Compared with existing technologies, the technical solution of this application not only achieves more precise environmental monitoring but also enables remote alarm and monitoring through the remote control and upgrade module 4, further enhancing the system's intelligence level.
