[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this technical field without creative work are within the scope of protection of the utility model.
[0028] See also Figure 1 , Figure 1 It is a structural block diagram of an aircraft air conditioning inspection system provided by an embodiment of the utility model, wherein the aircraft air conditioning inspection system comprises a plurality of temperature data acquisition modules 1, a data receiving module 2 and a data visualization module 3;
[0029] Each of the temperature data acquisition modules 1 includes at least one temperature measurement module 101 and at least one data sending module 102, and each of the temperature measurement modules 101 is correspondingly connected to each of the data sending modules 102;
[0030] Each of the data sending modules 102 is communicatively connected to the data receiving module 2 , and the data receiving module 2 is connected to the data visualization module 3 .
[0031] For example, when it is necessary to inspect the aircraft air conditioning system, several temperature data acquisition modules 1 are pre-installed at the corresponding temperature measurement points in the aircraft air conditioning duct, wherein each temperature measurement module 101 collects the temperature data of each position of the air conditioning system in real time, each data sending module 102 reads the temperature data of the temperature measurement module 101 at regular intervals and sends it to the data receiving module 2, the data receiving module 2 sends the received temperature data to the data visualization module, and the data visualization module can display the data in the form of a graph, table or other form. The utility model can simultaneously measure multiple air conditioning duct positions in a short time, thereby improving the inspection efficiency of the aircraft air conditioning system, and at the same time, there is no need for manual handheld temperature testers to be tested in high temperature areas, which can reduce the risk of personal injury, thereby improving the safety of aircraft air conditioning inspection.
[0032] As an improvement of the above solution, each of the temperature measurement modules includes at least one temperature sensor.
[0033] Preferably, the temperature sensor is a columnar temperature sensor.
[0034] It is worth mentioning that the use of columnar temperature sensors can improve the accuracy and reliability of temperature measurement and is suitable for high-demand measurement scenarios. At the same time, the columnar design makes the integration and installation of the sensor in the system more convenient, reducing installation complexity and cost.
[0035] Specifically, the columnar temperature sensor is a DS18B20 temperature sensor.
[0036] It should be noted that DS18B20 is a commonly used high-precision single-bus digital temperature sensor with the characteristics of small size, low hardware overhead, strong anti-interference ability and high accuracy. The operating voltage of DS18B20 is 3.0-5.0V and the temperature measurement range is -55℃ to +125℃, and the error is within ±0.5℃ from -10℃ to +85℃.
[0037] See also Figure 2 , Figure 2 : is a structural block diagram of a temperature data acquisition module of an aircraft air conditioning inspection system provided by an embodiment of the utility model, such as Figure 2 As shown:
[0038] Each of the data transmission modules 102 includes a wireless transmission module 1022, a transmission antenna component 1021 and a power supply module 1023;
[0039] Each of the wireless transmission modules 1022 is connected to each of the temperature sensors 1011;
[0040] The transmitting antenna assembly 1021 and the power supply module 1023 are respectively connected to the wireless transmitting module 1022 .
[0041] It is worth noting that the wireless transmission module is directly connected to each temperature sensor to receive the temperature data of the sensor and send the data to the receiving end wirelessly; the transmitting antenna is connected to the wireless transmission module and is responsible for converting the electrical signal generated by the wireless transmission module into radio waves and transmitting them out; the power supply module is used to provide a stable power supply to the wireless transmission module to ensure its normal operation and data transmission. The power supply module can also include battery power monitoring and power management functions to optimize energy use and extend system operation time. Through this implementation, efficient and reliable wireless temperature data transmission can be achieved, and the long-term stable operation of the system can be ensured.
[0042] For example, the embodiment of the utility model selects a low-power wireless transmission module to connect the temperature sensor. In specific implementation, according to the measurement, it is found that the wireless transmission module used in the embodiment of the utility model consumes about 0.5mA of current per 1ms, which can be explained that the design in the embodiment of the utility model takes into account the balance between power consumption optimization and battery life, and can further ensure the effective and continuous transmission of temperature data.
[0043] Preferably, the power supply module is a detachable rechargeable battery.
[0044] It is worth noting that by adopting a detachable rechargeable battery, the battery life of the data sending module can be guaranteed and the maintainability of the data sending module can be guaranteed.
[0045] Specifically, the wireless sending module is an APC300 module.
[0046] For example, when the temperature measurement module is a DS18B20 temperature sensor and the data transmission module is an APC300 module, the APC300 module uses the DS18B20 mode (directly connects the APC300 module to the DS18B20 temperature sensor). Figure 3 , Figure 3 The following is a schematic diagram of a data transmission module and a temperature sensor of an aircraft air conditioning inspection system provided by an embodiment of the utility model. Figure 3As shown, DS18B20 can be directly connected to the APC300 module, and no peripheral devices are required. Among them, the APC300 module supports the measurement of 9-bit (byte) and 12-bit resolution of DS18B20. Since DS18B20 has a power consumption of about 1mA during measurement, and the maximum measurement time of 9-bit and 12-bit resolutions is 93.75ms and 750ms respectively, if there are special requirements for power consumption, 9-bit resolution can be selected. At this time, the power consumption of DS18B20 is only one-eighth of that of 12-bit resolution. The APC300 module will measure regularly and upload the data of Byte0 (Temperature LSB) and Byte1 (Temperature MSB) of DS18B20.
[0047] Through actual measurement, the APC300 module consumes only about 1mA of power. Specifically, the transmission data format in DS18B20 mode is:
[0048] ID(2byte GroupID+SlaveID)+Data(2byte)+Bat(1byte);
[0049] There are 5 bytes in total. If the transmission rate is 50Kbps, the transmission time is about 2.4ms. This proves that the APC300 module can meet the interval requirements of aircraft air conditioning temperature measurement.
[0050] See also Figure 4 , Figure 4 The present invention provides a structural block diagram of a data receiving module of an aircraft air conditioning inspection system, such as Figure 4 As shown:
[0051] The data receiving module 2 includes a wireless receiving module 202, a receiving antenna component 201 and a transmission interface component 203;
[0052] The receiving antenna component 201 and the transmission interface component 203 are respectively connected to the wireless receiving module 202;
[0053] The data receiving module 2 is connected to the data visualization module 3 via the transmission interface component 203 .
[0054] It should be noted that the receiving antenna component is responsible for receiving the signal transmitted by the wireless receiving module, converting the radio wave into an electrical signal and transmitting it to the wireless receiving module; the wireless receiving module is used to receive the wireless signal from the data sending module, decoding the received signal and converting it into a processable data format; the transmission interface component transmits the processed data from the wireless receiving module to other terminal systems or devices, such as data visualization modules, data storage or processing systems. This approach optimizes the data reception and processing process and can improve the overall performance of the aircraft air conditioning inspection system.
[0055] It should be noted that when using multiple temperature data acquisition modules to collect aircraft air conditioning temperature data, in order to ensure reliable transmission of data signals, it is necessary to select a data receiving module that matches the data sending module in the temperature data acquisition module, and the data module parameters of the receiving end and the sending end must be consistent.
[0056] Preferably, a data receiving module can be used to uniformly receive all data transmitted from the data sending modules. However, it is necessary to ensure that the frequency and other parameter settings of the data receiving module match those of all data sending modules to achieve correct communication; at the same time, by adding a unique identifier (such as ID), a predefined unique code or a serial number to the data sent by each data sending module to distinguish different data sending modules, the data receiving module can determine the source of the data by parsing these identifiers when receiving the data.
[0057] Specifically, the wireless receiving module is an APC250S module.
[0058] It should be noted that the APC300 module is a unidirectional transmitting module, so the reception is completed by the APC250S module. The APC250S module is a highly integrated single-receiver wireless data transmission module. It uses a high-speed single-chip microcomputer and a high-performance RF chip. It has extremely high sensitivity and low power consumption. It also provides multiple channel options and can modify various parameters such as serial port rate, transmission power, RF rate, etc. online.
[0059] For example, the APC300 and APC250S modules can be set up using the PC serial port through the setting software RF-SENSOR. The APC300 and APC250S modules have rich and convenient software programming setting options, including frequency, air rate, serial port rate, calibration method, sensor type, etc. The setting method is to first connect the communication line, open the RF-SENSOR software, then turn on the module power, and finally insert the module into the setting board. When the status bar of the RF-SENSOR software should display Found Device (module), you can perform the corresponding read and write operations. The setting method of the APC300 and APC250S modules is the same.
[0060] Preferably, the transmission interface component is a USB interface component.
[0061] It is worth mentioning that the USB interface is a widely used standard interface with strong compatibility and is easy to connect to various computers and devices. The USB interface supports high-speed data transmission and has plug-and-play features, which simplifies the device connection and configuration process and improves user convenience.
[0062] Preferably, the data visualization module comprises a liquid crystal display.
[0063] It is worth mentioning that the temperature changes at various positions of the air-conditioning duct can be displayed in real time and dynamically through visualization devices including liquid crystal displays, so that data backtracking can be achieved based on the received data, so as to facilitate the subsequent use of the received data to simulate the dynamic process of air-conditioning temperature measurement and monitor the temperature condition of the aircraft air-conditioning.
[0064] In summary, an aircraft air conditioning inspection system provided by an embodiment of the utility model includes several temperature data acquisition modules and a data visualization module; the temperature data acquisition module includes several temperature measurement modules and several data sending modules, each of the temperature measurement modules is correspondingly connected to each of the data sending modules; the data sending module is communicatively connected to the data receiving module, and the data receiving module is connected to the data visualization module. The utility model can detect the temperature of the aircraft air conditioning system by simultaneously installing multiple temperature data acquisition modules on multiple measurement points corresponding to the temperature of the air conditioning duct. The utility model can simultaneously measure multiple air conditioning duct positions in a short time, thereby improving the inspection efficiency of the aircraft air conditioning system. At the same time, there is no need for manual handheld temperature testers to be tested in high temperature areas, reducing the risk of personal injury and improving the safety of aircraft air conditioning inspection.
[0065] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
