[0002] Multi-channel communication, as the name suggests, refers to the simultaneous establishment and maintenance of multiple communication links in a communication system. The purpose of multi-channel communication is to improve the reliability, stability, and efficiency of data transmission, and to cope with possible communication failures or network congestion through redundancy and load balancing.

[0003] Currently, when air conditioners are mounted with these devices, each device has an independent power supply and switch, and then connected to a switch. The switch needs to be connected to the Internet and also to fiber optic transceivers, routers and other devices. This method of connecting devices to the Internet causes great trouble for installation and maintenance personnel during the installation, wiring and maintenance process. In addition, the equipment is out of control and has a slow response rate. If a problem occurs with a device, it must be checked and replaced on site, which increases the cost of use and maintenance.

[0004] Therefore, it is urgent to improve the multi-channel communication circuit** of the air-conditioning aggregation gateway to solve the above-mentioned problems. Utility Model Content

The air-conditioning aggregation gateway can aggregate multiple communication links into one logical link through the multi-channel communication circuit. Even if a link fails or becomes unstable, the other links can still maintain communication, thereby ensuring continuous data transmission. The aggregated link has higher bandwidth and lower latency, which can meet the air-conditioning system's requirements for data transmission speed and real-time performance, and improve the stability, reliability and response speed of the entire communication system.

[0028] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0029] like Figure 1-Figure 3 As shown, the multi-channel communication circuit of the air conditioning aggregation gateway provided in this embodiment includes a data processing unit 1 and multiple indoor unit interface modules 2 and outdoor unit interface modules 3 provided on the data processing unit 1. Several indoor unit interface modules 2 are electrically connected to indoor units 201 respectively, and several outdoor unit interface modules 3 are electrically connected to outdoor units 301 respectively.

[0030] The data processing unit 1 includes a multiplexer U101. The interior of the indoor interface module 2 and the exterior interface module 3 are electrically connected to a number of drivers 202. The multiplexer U101 is electrically connected to the drivers 202. The drivers 202 are arranged inside the exterior interface module 2 or the indoor interface module 3. The air conditioning aggregation gateway can aggregate multiple communication links into one logical link through a multi-channel communication circuit. In this way, even if a link fails or becomes unstable, other links can still maintain communication, thereby ensuring continuous data transmission. The aggregated link has higher bandwidth and lower latency, which can meet the air conditioning system's requirements for data transmission speed and real-time performance. The multi-channel communication circuit can intelligently distribute data traffic to each link to achieve load balancing, which helps to avoid congestion or failure of a link due to excessive load, thereby improving the stability and reliability of the entire communication system.

[0031] Multi-channel communication circuits can quickly switch to other normal links to ensure uninterrupted communication. This fault switching mechanism is crucial for air conditioning systems because any communication interruption may cause the system to malfunction. By distributing encrypted data to different links through multi-channel communication circuits, even if the data on a link is intercepted, the original data cannot be easily restored, thereby enhancing the security of data transmission.

[0032] Further, such as Figure 2 As shown, the NO1A pin and the NO1B pin of the multiplexer U101 are electrically connected to the driving interface IC3;

[0033] The NO2A pin and the NO2B pin of the multiplexer U101 are electrically connected to the driver interface IC4;

[0034] The NO3A pin and the NO3B pin of the multiplexer U101 are electrically connected to the driver interface IC5;

[0035] The NO4A pin and the NO4B pin of the multiplexer U101 are electrically connected to the driver interface IC6;

[0036] The drive interface IC3, the drive interface IC4, the drive interface IC5 and the drive interface IC6 are all electrically connected to the indoor unit interface module 2 or the outdoor unit interface module 3. The power supply module 4 is connected to the pin COMA and the pin COMB of the multiplexer U101. The V+ pin of the power supply module 4 is electrically connected to the V+ pin of the multiplexer U101, and the V- pin of the power supply module 4 is electrically connected to the V- pin of the multiplexer U101. A transmitting optocoupler and a receiving optocoupler are provided inside the indoor unit 201. A timing switch RC1 is provided on the transmitting optocoupler, and a timing switch RC2 is provided on the receiving optocoupler 1. A transmitting optocoupler and a receiving optocoupler are provided inside the outdoor unit 301. A timing switch RC11 is provided on the transmitting optocoupler, and a timing switch RC22 is provided on the receiving optocoupler. A resistor R is provided in series between the timing switches RC2 and RC22. N and resistor R W The multi-channel communication circuit enables the air conditioning aggregation gateway to adapt to different types of network environments, whether wired or wireless, broadband or narrowband, and can find the most suitable communication method. This flexibility enables the air conditioning system to achieve stable and reliable communication in more scenarios.

[0037] Furthermore, Figure 1 As shown, the power supply module 4 includes a transformer, a rectifier bridge, a capacitor, an inductor and a voltage stabilizing chip. The transformer converts the high voltage of the AC power into a low voltage, or converts the low voltage into a high voltage, to provide the voltage required by the circuit. The rectifier bridge converts the AC power into DC power. It is composed of four diodes and can convert the positive and negative half cycles of the AC power into forward and reverse pulse currents respectively. The current is then smoothed and filtered by the capacitor to finally obtain stable DC power.

[0038] Capacitors store charge and are used to smooth voltage to ensure stable circuit operation. Large capacitors are generally used in power modules. The larger the capacity, the better the smoothing output effect. Inductors store magnetic fields to prevent sudden changes in current and ensure the stability of circuit operation. In power modules, inductors are often used in LC filtering circuits, and the output voltage is further smoothed by the collaborative capacitor. The voltage regulator chip adjusts the input voltage to output a stable voltage.

[0039] Further, if Figure 1 As shown, the data processing unit 1 is electrically connected to the LED display 5, and the data processing unit 1 and the power supply module 4 are arranged inside the LED display 5, so that the communication on and off can be observed intuitively, thereby improving the convenience of use.

[0040] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0041] It should be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or system comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or system. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0042] The above description shows and describes several preferred embodiments of the present invention. However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Instead, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge in the relevant field.
