[0040] In order to solve the technical problems of large data transmission delay and low efficiency in air-conditioning systems in the prior art, the present application provides a data transmission method applied to air conditioning. By storing the sensing data in the air-conditioning system in a cache, the risk of data loss can be reduced, the forwarding of multi-channel sensor data can be supported, and the amount and efficiency of data transmission can be improved.

[0041] Figure 1 A flow chart of a data transmission method applied to an air conditioner provided in an embodiment of the present application. The method can be applied to an air-conditioning system, and the method can be executed by an electronic device such as a control unit in the air-conditioning system, or by other electronic devices connected to the air conditioner. In addition, the execution subject of the method can be hardware or software. When the above-mentioned execution subject is hardware, the execution subject can be one or more of the above-mentioned electronic devices. For example, a single electronic device can execute the method, or a plurality of electronic devices can cooperate with each other to execute the method. When the above-mentioned execution subject is software, the method can be implemented as multiple software or software modules, or as a single software or software module. No specific limitation is made here.

[0042] like Figure 1 As shown, the method specifically includes:

[0043] Step 101: Acquire sensing data sent by a first device on the air conditioning system.

[0044] In some embodiments, the first device may be various devices in the air-conditioning system, for example, an indoor unit or an outdoor unit. The number of the first devices may be one or more. The sensing data is data collected by a sensor on the first device. For example, when the first device is an outdoor unit of an air conditioner, the sensing data may be refrigerant pressure data, humidity data, motor speed data, temperature data, etc.; when the first device is an indoor unit of an air conditioner, the sensing data may be indoor temperature data, indoor humidity data, air supply motor speed data, oxygen concentration data, etc.

[0045] The electronic device executing the method may directly receive the sensing data from the sensor, or may process (eg, filter, screen, etc.) the data collected by the sensor to obtain the sensing data.

[0046] Step 102: store the sensing data in a preset buffer.

[0047] In some embodiments, a buffer may be provided in an electronic device that executes the method, and after the electronic device acquires the sensing data, it may store the sensing data in the buffer. Optionally, the buffer may be operated in various ways. For example, a FIFO (First In First Out) queue may be used to store the sensing data in the buffer, that is, multiple sensing data may be stored in the buffer in sequence according to the acquisition time of the sensing data.

[0048] Step 103 : in response to triggering a read instruction for the sensing data, reading the sensing data from the buffer.

[0049] In some embodiments, the read instruction can be triggered when the above-mentioned electronic device meets the read condition. For example, if the electronic device is currently in a busy state, that is, it is processing other data, it is determined that it does not meet the read condition; if it is in an idle state, it is determined that it meets the read condition, and the read instruction can be triggered at this time. Read instructions triggered at different times correspond to different sensing data. For example, when storing sensing data, the address of the sensing data can be recorded. If the read instruction is triggered at the current moment, and the address read at the current moment is the address of the above-mentioned sensing data, the above-mentioned sensing data is read from the storage unit corresponding to the address.

[0050] Step 104: determine a second device in the air conditioning system for receiving the sensing data.

[0051] In some embodiments, the correspondence between the second device and the sensing data can be pre-set, and the corresponding second device can be determined based on the attribute information of the sensing data (such as type, identification, source, etc.). The number of first devices can be one or more. For example, if the first device is an outdoor unit of an air-conditioning system, the sensing data collected by the outdoor unit needs to be forwarded to the indoor unit by the electronic device that executes this method, and the indoor unit can serve as the second device. Similarly, if the first device is an indoor unit, the sensing data collected by the indoor unit needs to be forwarded to the outdoor unit by the electronic device that executes this method, and the outdoor unit can serve as the second device.

[0052] Step 105: Send the sensing data to the second device.

[0053] In some embodiments, the electronic device executing the method may send the sensing data to the second device through an interface with the second device.

[0054] The data transmission method applied to the air conditioner provided in the embodiment of the present application obtains the sensing data sent by the first device on the air conditioning system, stores the sensing data in a buffer, and when a read instruction for the sensing data is triggered, reads the sensing data from the buffer, and sends the sensing data to the second device in the air conditioning system. The embodiment of the present application realizes that the sensing data collected in the air conditioning system is temporarily stored in the buffer, and when forwarding the data, the data is read from the buffer and sent. When the data transmission volume is large, the risk of data loss can be reduced by this method, and because the buffer can store multiple data, the method can be applied to the forwarding of multi-channel sensor data, thereby improving the quantity and efficiency of data transmission.

[0055] In some optional implementations, such as Figure 2 As shown, step 101 includes:

[0056] Step 1011: In response to receiving an analog signal collected by a sensor on the first device, preprocess the analog signal to obtain a processed signal.

[0057] The analog signal may be a signal collected by various types of sensors. For example, when the first device is an air conditioner outdoor unit, the analog signal may be a signal collected by a piezoresistive effect sensor, a capacitive humidity sensor, a Hall sensor, a temperature sensor data, a capacitive pressure sensor, etc.

[0058] In order to improve the accuracy of data acquisition, the analog signal needs to be preprocessed. The preprocessing method can be preset, such as filtering, amplification and other preprocessing methods.

[0059] Step 1012: Perform analog-to-digital conversion on the processed signal to obtain the sensing data.

[0060] The processed signal is still an analog signal, and an analog-to-digital converter can be used to perform analog-to-digital conversion on the processed signal to obtain sensing data in digital form, so that the sensing data can be stored in a buffer.

[0061] This embodiment can improve the quality of the collected analog signals and further improve the accuracy of the sensing data by preprocessing the collected analog signals and performing analog-to-digital conversion.

[0062] In some optional implementations, such as Figure 3 As shown, the step 1011 includes:

[0063] Step 10111, determine the type of the analog signal.

[0064] The type of the analog signal can be determined by the interface number for receiving the analog signal, that is, different analog signals are received by corresponding interfaces, and the type of the analog signal is determined based on the interface number. Alternatively, the interface number can be directly used as the type of the analog signal.

[0065] Step 10112: If the analog signal is of the first preset type, filter the analog signal, amplify the filtered analog signal, and determine the amplified analog signal as the processed signal.

[0066] Among them, the analog signal of the first preset type can be a signal with a low amplitude that needs to be amplified. For example, the signals collected by piezoresistive effect sensors, capacitive humidity sensors, Hall sensors, etc. The amplitude of these signals is low and needs to be amplified before they can be converted into digital signals. Optionally, this embodiment can use a multi-stage filter for filtering to improve the filtering effect. The multi-stage filter can include cascaded high-pass filters, low-pass filters and other parts, and the type and number of filters can be set according to actual needs. The multi-stage filter removes high-frequency noise and low-frequency noise from the collected signals in turn, ensuring that the signal remains stable during transmission and processing, and improving the reliability of the system.

[0067] Step 10113: If the analog signal is of the second preset type, filter the analog signal, and determine the filtered analog signal as the processed signal.

[0068] The second preset type of analog signal may be a signal with a relatively high amplitude that does not need to be amplified, such as a signal collected by a temperature sensor, a capacitive pressure sensor, etc. These signals have a relatively high amplitude and can be converted into digital signals without amplification.

[0069] This embodiment classifies analog signals collected by different sensors and amplifies specific types of analog signals, thereby facilitating more accurate analog-to-digital conversion and improving the accuracy of data collection.

[0070] In some optional implementations, such as Figure 4 As shown, step 102 includes:

[0071] Step 1021, read the write enable flag and fill level variable corresponding to the buffer.

[0072] Among them, the write enable flag is a preset variable used to indicate whether the buffer is currently in a writable state. For example, the write enable flag is wr_en. If wr_en=0, it means that the buffer is currently unable to write data due to being busy or faulty; if wr_en=1, it means that the buffer is currently able to write data. The fill level variable is a preset variable used to indicate the amount of data currently stored in the buffer. The fill level variable is level. The higher the level value, the larger the amount of data stored in the buffer, that is, the smaller the remaining storage capacity.

[0073] Step 1022: If the write enable flag indicates that the buffer is currently in a writable state, and the fill level variable indicates that the buffer is currently not full, read the write pointer corresponding to the buffer.

[0074] Continuing the above example, if wr_en=1, and level is less than the preset maximum value, it is determined that the buffer is not full, and the write pointer can be read at this time. The write pointer indicates the address of a storage unit in the buffer, and the sensing data can be written into the currently idle storage unit according to the write pointer.

[0075] Step 1023: store the sensing data in the buffer according to the write pointer.

[0076] Usually, after the sensing data is written into the buffer, the write pointer needs to be updated to point to a new free storage unit.

[0077] This embodiment can determine the state of the buffer in real time by setting the write enable flag and the fill level variable, ensuring that the sensing data can be stored in the buffer, thereby improving the stability and accuracy of data transmission.

[0078] In some optional implementations, such as Figure 5 As shown, step 103 includes:

[0079] Step 1031, read the read enable flag and fill level variable corresponding to the buffer.

[0080] The read enable flag is a preset variable used to indicate whether the buffer is currently in a readable state. The fill level variable is the same as the fill level variable in the above step 1021. For example, the read enable flag is rd_en. If rd_en=0, it means that the buffer is currently unable to read data due to reasons such as being busy or faulty; if rd_en=1, it means that the buffer is currently able to read data.

[0081] Step 1032: If the read enable flag indicates that the buffer is currently in a readable state, and the fill level variable indicates that the buffer is currently in a non-empty state, read the read pointer corresponding to the buffer.

[0082] Continuing the above example, if rd_en=1, and level indicates that the buffer is not empty, it is determined that the buffer can be read, and the read pointer can be read at this time. The read pointer indicates the address of a storage unit containing data in the buffer, and data can be read from the corresponding storage unit according to the read pointer.

[0083] Step 1033: read the sensing data from the buffer according to the read pointer.

[0084] Usually, after reading data from the buffer, the read pointer needs to be updated to point to the next storage unit to be read.

[0085] Optionally, this embodiment can be combined with the above Figure 4 The embodiments shown are combined to implement a FIFO read and write mode for the buffer. That is, the write pointer always points to the next storage unit of the storage unit where data was written most recently, and the read pointer always points to the storage unit to be read. Therefore, after each data is written or read, the write pointer and the read pointer are increased by 1. When the write pointer is equal to the read pointer, it means that the buffer is currently empty, and the write pointer and the read pointer are reset.

[0086] This embodiment can determine the state of the buffer in real time by setting the read enable flag and the fill level variable, ensuring that the sensing data can be read from the buffer, thereby improving the stability and accuracy of data transmission.

Specifically comprising: an acquisition module 601, used to acquire sensing data sent by a first device on an air conditioning system, wherein the sensing data is data collected by a sensor on the first device; a storage module 602, used to store the sensing data in a preset buffer; a reading module 603, used to extract the sensing data from the buffer in response to triggering a read instruction for the sensing data; a determination module 604, used to determine a second device in the air conditioning system for receiving the sensing data; and a sending module 605, used to send the sensing data to the second device.

[0088] In some optional implementations, the acquisition module includes: a preprocessing unit, used to preprocess the analog signal in response to receiving the analog signal collected by the sensor on the first device to obtain a processed signal; and a conversion unit, used to perform analog-to-digital conversion on the processed signal to obtain the sensing data.

[0090] In some optional implementations, the storage module includes: a first reading unit, used to read a write enable flag and a fill level variable corresponding to the cache; a second reading unit, used to read a write pointer corresponding to the cache if the write enable flag indicates that the cache is currently in a writable state and the fill level variable indicates that the cache is currently not full; and a storage unit, used to store the sensing data in the cache according to the write pointer.

[0091] In some optional implementations, the reading module includes: a third reading unit, used to read a read enable flag and a fill level variable corresponding to the buffer; a fourth reading unit, used to read a read pointer corresponding to the buffer if the read enable flag indicates that the buffer is currently in a readable state and the fill level variable indicates that the buffer is currently in a non-empty state; and a fifth reading unit, used to read the sensing data from the buffer according to the read pointer.

[0092] The data transmission device for air conditioner provided in this embodiment can be as follows: Figure 6 The data transmission device applied to the air conditioner shown in can execute all steps of the above data transmission methods applied to the air conditioner, and then realize the technical effects of the above data transmission methods applied to the air conditioner. Please refer to the above related description for details. For the sake of brevity, it will not be repeated here.

[0093] Figure 7 A schematic diagram of the structure of an air conditioning system provided in an embodiment of the present application, specifically comprising: a data transceiver module 701, an outdoor unit 702 and at least one indoor unit 703, wherein the data transceiver module 701 comprises a buffer 7011. The data transceiver module 701 is disposed between the at least one indoor unit 703 and the outdoor unit 702, and is connected to the at least one indoor unit 703 and the outdoor unit 702.

[0094] like Figure 7As shown, when the number of indoor units is greater than 1 (including indoor unit 1-indoor unit N, a total of N indoor units), the air conditioning system can be a multi-connected air conditioning system. Since the multi-connected air conditioning system includes a large number of sensors and other equipment, and the amount of data transmitted and processed is large, the data transceiver module 701 in this embodiment can be used to perform multi-channel data forwarding.

[0095] The data transceiver module 701 may include a device with logic processing capability, signal conditioning capability, and data storage capability. The data transceiver module 701 is used to execute the data transmission method applied to the air conditioner described in the above embodiments. When the data transceiver module 701 receives a signal from any indoor unit, the indoor unit is the first device, and the outdoor unit 702 is the second device; when the data transceiver module 701 receives a signal from the outdoor unit 702, the outdoor unit 702 is the first device, and the at least one indoor unit 703 is the second device. That is, when the data transceiver module 701 receives the sensing data of the indoor unit, the sensing data is sent to the outdoor unit 702, and the outdoor unit 702 performs a corresponding function (such as setting the compressor power, etc.) according to the received sensing data; when the data transceiver module 701 receives the sensing data of the outdoor unit 702, the sensing data is sent to each indoor unit, and the indoor unit performs a corresponding function (such as setting the wind speed, etc.) according to the received sensing data.

[0096] The air-conditioning system provided in the embodiment of the present application, by setting a data transceiver module in the air-conditioning system, uses the data transceiver module to transmit data between the indoor unit and the outdoor unit, temporarily stores the collected multi-channel sensing data in a buffer, and when forwarding data, reads the data from the buffer and sends the data. When the data transmission volume is large, the risk of data loss can be reduced, and because the buffer can store multiple data, the method can be applied to the forwarding of multi-channel sensor data, thereby improving the amount and efficiency of data transmission.

[0097] In some optional implementations, such as Figure 8 As shown, the data transceiver module 701 includes a control unit 7012, a signal preprocessing unit 7013 and an analog-to-digital converter 7014, the control unit 7012, the signal preprocessing unit 7013 and the analog-to-digital converter 7014 are connected in sequence, and the buffer 7011 is connected to the analog-to-digital converter 7014 and the control unit 7012. The buffer 7011 can receive a digital signal sent by the analog-to-digital converter 7014 and store the digital signal, or send data read by the control unit 7012 to the control unit 7012.

[0098] The control unit 7012 is used for: in response to receiving an analog signal collected by a sensor on the first device, sending the analog signal to the signal preprocessing unit 7013.

[0099] For example, when the first device is an air conditioner outdoor unit 702, the analog signal may be a signal collected by a piezoresistive effect sensor, a capacitive humidity sensor, a Hall sensor, temperature sensor data, a capacitive pressure sensor, etc.

[0100] The signal preprocessing unit 7013 is used to preprocess the analog signal to obtain a processed signal, and send the processed signal to the analog-to-digital converter 7014.

[0101] In order to improve the accuracy of data collection, the analog signal needs to be preprocessed. The preprocessing method can be preset. For example, a filter, an amplifier and other devices are set in the signal preprocessing unit 7013 to perform preprocessing such as filtering and amplification on the processed signal.

[0102] The analog-to-digital converter 7014 is used to perform analog-to-digital conversion on the processed signal to obtain sensing data, and send the sensing data to the buffer 7011 .

[0103] The performance indicators of the analog-to-digital converter 7014 include resolution, conversion rate, quantization error, offset error, full-scale error, linearity, etc. The analog-to-digital converter 7014 used in this embodiment can be set according to requirements. For example, an analog-to-digital converter 7014 with characteristics such as 16-bit 6-channel input, wide dynamic range, high resolution, low noise, small integral error and small temperature drift is selected, and the full-scale programmable is required to adapt to input signals of different strengths, thereby improving conversion accuracy and reducing noise.

[0104] This embodiment can improve the quality of the collected analog signals and further improve the accuracy of the sensing data by preprocessing the collected analog signals and performing analog-to-digital conversion.

[0105] In some optional implementations, the control unit 7012 is a programmable logic chip. The programmable logic chip can implement certain logic processing functions through programming. For example, the programmable logic chip used in this embodiment can be an FPGA (Field Programmable Gate Array) chip, which has a high degree of flexibility and parallel processing capabilities, contains a large number of logic units and interconnection resources, can perform multiple tasks while achieving high speed and high precision, and can provide lower latency, thereby improving the synchronization control accuracy of the outdoor unit 702 and the indoor unit of the air-conditioning system.

[0106] In some optional implementations, such as Fig. 9As shown, the signal preprocessing unit 7013 includes a first filter 70131, a signal amplifier 70132 and a second filter 70133, the first filter 70131 is connected to the control unit 7012 and the signal amplifier 70132, the signal amplifier 70132 is connected to the analog-to-digital converter 7014; the second filter 70133 is connected to the control unit 7012 and the analog-to-digital converter 7014.

[0107] The control unit 7012 is also used to: determine the type of the analog signal; if the analog signal is of a first preset type, send the analog signal to the first filter 70131; if the analog signal is of a second preset type, send the analog signal to the second filter 70133.

[0108] The first preset type of analog signal may be a signal with a low amplitude that needs to be amplified. For example, signals collected by a piezoresistive effect sensor, a capacitive humidity sensor, a Hall sensor, etc. These signals have a low amplitude and need to be amplified before they can be converted into digital signals. The second preset type of analog signal may be a signal with a high amplitude that does not need to be amplified. For example, signals collected by a temperature sensor data, a capacitive pressure sensor data, etc. These signals have a high amplitude and can be converted into digital signals without amplification.

[0109] The first filter 70131 is used to filter the analog signal and send the filtered analog signal to the signal amplifier 70132.

[0110] Optionally, this embodiment can use a multi-stage filter for filtering to improve the filtering effect. The multi-stage filter may include a cascaded high-pass filter, a low-pass filter and other parts, and the type and number of filters can be set according to actual needs. The multi-stage filter removes high-frequency noise and low-frequency noise from the collected signal in turn, ensuring that the signal remains stable during transmission and processing, and improving the reliability of the system.

[0111] The signal amplifier 70132 is used to amplify the filtered analog signal and send the amplified analog signal to the analog-to-digital converter 7014.

[0112] The signal amplifier 70132 amplifies the weak analog signal in proportion to ensure easy identification of data collection. Optionally, a controllable gain amplifier can be used as the signal amplifier 70132. The controllable gain amplifier can be controlled by the control unit 7012, and different amplification factors (such as 16 different amplification factors such as 1 to 8000) can be achieved in a cascade manner according to different gain ranges to meet the requirements of data collection.

[0113] The second filter 70133 is used to filter the analog signal and send the filtered analog signal to the analog-to-digital converter 7014.

[0114] The structure of the second filter 70133 may be the same as or different from that of the first filter 70131 .

[0115] This embodiment classifies the analog signals collected by different sensors according to their amplitudes, and the signal conditioning circuit is composed of the above-mentioned first filter and signal amplifier, which can filter and amplify the weak signals collected by the sensor, thereby facilitating more accurate analog-to-digital conversion and improving the accuracy of data collection.
