[0040] J. PC communication: 19200bps, can be connected with Testlogging logging software.

[0041] The specific functions and working principles of each group of functional boards 9 are as follows:

[0042] The power communication board 1 includes a multi-channel frequency signal acquisition module and an RS232 data upload module. Together with the PC-side logging software, it can display multiple signals at the same time, thus realizing the collection and storage of multiple data. The four input terminals are interconnected, and all four input terminals can be used as input terminals. Once a USB terminal is damaged, the other USB terminals can also be used.

[0043] Temperature measurement principle of temperature pressure test card 91: constant current source power supply, 24bit single-ended signal acquisition, simple circuit, temperature parameters do not need to be calibrated, the implementation principle is as follows:

[0044] Assume that the constant current source current is I 0 , the temperature probe voltage is V 0 , the sampling resistor R is a high-precision low-temperature drift resistor, the voltage reference source size is Vref, the temperature probe internal resistance is Rpt, and the data collected by the AD chip is DATA. According to Ohm's law formulas 1 and 2:

[0045] Vref=I*(Rpt+R) (1)

[0046] V 0 =I*R (2)

[0047] According to AD acquisition principle formula 3:

[0048] V 0 =DATA*Vref / 2 23 (3)

[0049] Combining formulas 1, 2, and 3, we can obtain formula 4 by calculation:

[0050] Rpt=R*(2 23 / DATA-1) (4)

[0051] From this formula, it can be concluded that the internal resistance of the temperature probe is related to the AD acquisition accuracy and linearity and the accuracy and temperature drift of the sampling resistor R. It is very important to select the AD chip and sampling resistor R within the overall accuracy range of the temperature parameters. After evaluation by means of selection, high temperature testing and other detection methods, the actual temperature measurement accuracy fully meets the logging needs.

[0052] Pressure measurement principle: It also uses a constant current source for power supply, the supply current is 1mA, 24-bit AD is directly collected, and the power supply section is also used as the reference voltage for AD collection. It also eliminates the influence of constant current source current temperature drift, and is only related to the various parameters of the AD chip.

[0053] After the temperature and pressure parameters are collected, their respective digital sizes are converted into pulse signals with equal frequency values, and then switched to the display digital tube through a switch.

[0054] The key component in the turbine detection board 92 is the Hall element. When the Hall element approaches the magnet, the power supply pin level of the Hall element will be slightly pulled down. The pull-down signal is converted into a TTL level signal through the comparator device, transmitted to the display acquisition microcontroller, and then displayed on the digital display. In this way, the working status of the turbine sensor can be judged by observing the digital display after simulating the blowing of the turbine.

[0055] The gamma high temperature plateau detection board 93 includes a power conversion module, a high voltage power supply module, a high voltage measurement head, a first adjustable resistor and a first high voltage filter module. The overall power supply is +5V. The power conversion module converts +5V into +15V, and +15V provides power for the high voltage power supply module. The high voltage measurement head can measure the high voltage size after the high voltage power supply module filters the output, and the first adjustable resistor is used to adjust the high voltage output size.

[0056] The high voltage measurement board 94 includes a high voltage measurement meter, a second adjustable resistor and a second high voltage filter module. The high voltage measurement meter can measure the high voltage output after filtering by the high voltage power module, and the second adjustable resistor is used to adjust the high voltage output.

[0057] The multi-channel low-voltage measurement board 95 includes three voltage and current meters, which can measure the three-channel voltage and output current of the power module. The board also includes multiple load resistors, which can switch loads of different resistance values ​​through a torsion switch, thus realizing the three-channel output voltage and output current of the power module.

[0058] The frequency signal generator board 96 includes two parts: a digital display and controller and a frequency signal generating microcontroller. The frequency signal generating microcontroller collects the middle tap voltage of the external potentiometer and then converts it into a frequency pulse signal that changes linearly with the voltage. The signal is transmitted to the display controller to display the current frequency size.

[0059] The test board 2 is specifically a low-voltage power supply four-way load test board, which contains four power isolation modules and four voltage and current meters (with constant current function). It can measure the four-way voltage and adjustable output current output by the power module. The board does not contain load resistance because the meter head has an adjustable current function. The power isolation module provides isolated power supply and protection for the four voltage and current meters.

[0060] Preferably, the device also includes a heat dissipation component for dissipating heat from the power communication board 1, the test board 2, and the functional board 9, including the temperature and pressure check card 91, the turbine detection board 92, the gamma high temperature plateau detection board 93, the high pressure measurement board 94, the multi-channel low pressure measurement board 95, and the frequency signal generator board 96. The heat dissipation component includes a heat dissipation port 12 opened on the surface of the back plate 4, and a heat dissipation fan 13 is arranged at the corresponding position of the heat dissipation port 12. The surface of the heat dissipation fan 13 is threadedly connected with a locking rod 14, and one end of the locking rod 14 passes through the heat dissipation fan 13 and extends to the outside of the heat dissipation fan 13 and is threadedly connected to the surface of the back plate 4.

[0061] Through the setting of the heat dissipation component, when the device is in use, the user can turn on the heat dissipation fan 13 through the external controller. The operation of the heat dissipation fan 13 can draw out the air with higher temperature in the device from the heat dissipation port 12 to achieve the purpose of heat dissipation. The heat dissipation fan 13 can be installed and fixed on the back panel 4 through the setting of the locking rod 14.

[0062] It is worth noting that the heat dissipation component also includes a plurality of groups of air inlets 15 opened on the surface of the side panel 3. The inner cavity of the air inlet 15 is fixedly installed with a filter 16. Through the setting of the air inlet 15, the air with a lower external temperature can be drawn into the device during the heat dissipation process, thereby improving the air circulation conditions in the device and further improving the heat dissipation effect of the device. The setting of the filter 16 can prevent external dust from entering the device through the air inlet 15.

[0063] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
