[0004] Specifically, drag cone tower calibration is a method for calibrating the airspeed pipe and static pressure sensor of an airplane, mainly used in the airspeed and calibration test flight of modern airplanes.

[0005] Drag cone tower calibration is a technology for calibrating the airspeed system of an airplane, which involves using a drag cone system to measure static pressure and comparing it with a high-precision pressure sensor on the ground tower to determine the system error.

[0006] Tower calibration is to measure the pressure value at the position of a high-precision pressure sensor placed on the tower. When the airplane flies over the tower height position, the pressure value is also measured. By comparing the measured pressure on the tower with the pressure measured by the drag cone, the error value is obtained.

[0007] Currently, in order to realize drag cone tower calibration, a data acquisition system needs to be established on the tower to complete the data acquisition task. Usually, a data acquisition system includes data acquisition devices, data recorders, switches, GPS antennas, debugging devices, sensors, DC power supplies, and interconnection cables between devices.

[0008] As can be seen, if a complete data acquisition system needs to be established, the system contains many devices and components, the system takes a long time to build and debug, the system is expensive, time-consuming and labor-intensive.

Rather, the present application is intended to cover various alternatives, modifications, equivalents, and other embodiments that are included in the spirit and scope of the present application as defined by the appended claims.

[0057] Hereinafter, referring to Figure 1 , the overall structure of the tower data acquisition device 1 of the present application will be described. Figure 1 is a diagram showing the overall structure of the tower data acquisition device 1 of the present application.

[0058] As shown in Figure 1 , the tower data acquisition device 1 of the present application mainly includes a housing 11, a display unit 12, a power unit 13, a sensor unit 14, and a data acquisition unit 15.

[0059] The housing 11 is formed in a substantially rectangular shape, mainly consists of a front panel 11a, a rear cover plate 11b, a side plate 11c, a bottom plate 11d, and a top plate 11e, and the entire tower data acquisition device 1 is integrated in the housing 11, thereby enabling miniaturization and portability of the entire acquisition device.

[0064] A rear cover plate 11b is provided at a position opposite to the front panel 11a. The rear cover plate 11b is provided with a debugging interface TSJK for connecting to a debugging computer and a power interface DYJK for connecting to an external power supply.

[0065] In addition, such as Figure 1 As shown, a power supply unit 13, a sensor unit 14, a data acquisition unit 15, and a GPS antenna TX are fixedly mounted on the aforementioned base plate 11d.

[0066] By modularizing and integrating the various functional parts onto the base plate 11d of the housing 11, the overall integration and miniaturization of the acquisition device can be achieved, resulting in a high degree of integration. This single acquisition device can replace the previous complete acquisition system.

[0078] In addition, a handle BS is arranged on the top plate 11e, through which an operator can conveniently move and carry the tower data collection device 1, so that data collection work can be performed in various different environments.

[0079] Preferably, a plurality of long slot holes CK are formed in the rear cover plate 11b, the side plate 11c, the bottom plate 11d and the top plate 11e respectively, which can function as heat dissipation holes to release heat generated by the tower data collection device 1 during work to the outside, so as to ensure the working performance of the tower data collection device 1.

[0084] Before the power switch of the acquisition device is turned on, the pressure value, the temperature value, the GPS signal state and the storage card state are checked through the display screen 12a and the indicator light 12b of the front panel 11a, and after confirming that each data / state is normal, the recording switch of the front panel 11a is turned on to start recording experimental data before the drag cone tower calibration test officially starts.

[0085] As shown in Figure 2 During the operation of the tower data acquisition device 1, the power supply unit 13 converts the alternating current power from the external power supply into direct current power and supplies it to the high-precision pressure sensor and the thermal resistance temperature sensor of the sensor unit 14 and the serial signal acquisition module, the temperature data acquisition module, the time conversion module, the data recording module and the debugging module of the data acquisition unit 15 respectively.

[0086] The high-precision pressure sensor outputs the pressure data in the form of a serial signal to the serial signal acquisition module, which transmits the digital signal to the data recording module after analyzing the serial signal.

[0087] The thermal resistance temperature sensor outputs the temperature data in the form of an analog signal to the temperature data acquisition module, which transmits the digital signal to the data recording module after analyzing the analog signal.
