[0018] Figure 1 The structural diagram of the tooling for improving the production efficiency of password cards provided by an embodiment of the present invention, the tooling for improving the production efficiency of password cards includes: A fixing frame 101, a control board 102 and an adapter board 103; The fixing frame 101 is used to fix the control board 102, the adapter board 103 and the password card to be tested; The control board 102 is used to control the power on and power off of the password card; The adapter board 103 is provided with a plurality of probes, which are used to connect with the cables of the control board 102 and transfer the password card to be tested to the control board 102, and transfer the password card to be tested to a host computer outside the control board for downloading core chip programs and security chip programs.
[0019] In the traditional password card production process, both the core chip and the security chip need to be connected to a dedicated download tool for burning, and the cable needs to be manually plugged in and out to connect to the download tool. At the same time, the password card needs to be manually connected to the server for password card initialization and password card quality inspection, which reduces the efficiency of password card production and testing, and increases the probability of damage to password card components or cables due to human factors.
[0020] The tooling for improving the production efficiency of password cards provided by the embodiment of the present invention comprises a fixing frame, a control board and an adapter board; the fixing frame is used to fix the control board and the adapter board; the control board is used to control the power on and off of the password card; a plurality of probes are arranged on the adapter board, the probes are used to connect with the cables of the control board, and transfer the control board to an external host computer for downloading core chip programs and security chip programs.

[0021] Based on any of the above embodiments, the step of performing characteristic analysis on the cargo in air cargo transportation to obtain the cargo characteristic analysis result includes: According to the tooling for improving the production efficiency of password cards provided by the present invention, the fixing frame includes a tooling cover, and the control panel is further used to monitor the pressing and lifting status of the tooling cover through interface instructions.
[0022] According to the tooling for improving the production efficiency of password cards provided by the present invention, the control board further comprises a USB interface, and the USB interface is used to burn programs into the core chip and the security chip of the password card to be tested.
[0023] According to the tooling for improving the production efficiency of password cards provided by the present invention, the USB interface is also used to obtain basic information of the password card to be tested and to perform algorithm testing and interface testing on the password card to be tested.
[0024] like Figure 2 As shown, the multiple probes include: at least one of a gold finger probe, a 3.3V power supply probe, a debugging probe, a connection performance test probe, a reset test probe, a security chip_DM probe, a security chip_DP probe and a ground probe.
[0025] In an embodiment of the present invention, the gold finger probe is a tool for testing the connection performance of the gold finger, which detects the electrical parameters of the gold finger by electrically connecting the probe to the gold finger. This probe-type alignment test fixture includes a probe electrically connected to the gold finger of an external test device and a mounting seat for mounting the probe. The mounting seat is a hollow structure with open ends, and is provided with an alignment guide sleeve hole integrally formed with the probe, which is intended to improve the alignment accuracy between the gold finger of the external test device and the gold finger to be tested, thereby improving the reliability and accuracy of the detection of the electrical parameters of the gold finger.
[0026] 3.3V powered probe refers to a probe that uses 3.3 volts to power the probe. This type of probe is often used in electronic devices and circuits that require precise voltage power supply to ensure the normal operation and performance of the device.
[0027] A debug probe (SWDIO probe) is a tool used to debug embedded systems. It is a type of debug probe. This type of probe is usually used with a specific debugging tool or platform. It is highly configurable and can be used with a variety of debug probes. The specific uses of SWDIO probes may include communicating with the target embedded system so that developers can inspect and modify the state of the program at runtime, thereby helping to debug and solve problems. In addition, the use of SWDIO probes may involve connecting to the internal debugging circuitry of the embedded system in order to perform password card testing and analysis through specific signal transmission detection tools.
[0028] The connection performance test probe (SWCLK probe) is a tool used to test PCBA (Printed Circuit Board Assembly), specifically a probe used to test the connection performance of electronic components. This probe is gold-plated on the surface and equipped with a high-performance spring inside. The probe is designed to accurately test the performance of the PCBA by forming a good electrical connection with the password card.
[0029] The reset test probe (JTAG_RESET probe) is the TRST pin in the JTAG interface, also known as the test reset pin. The JTAG (Joint Test Action Group) interface is an interface standard for chip testing and debugging, which defines several basic pin functions, including test clock input (TCK), test data input (TDI), test data output (TDO), test mode select (TMS), and optional test reset (TRST) pin. Among them, the TRST pin is a low-level active input pin used to implement the reset function of the test system. When the TRST pin is activated (generally in a low-level state), it can be used to reset the JTAG interface and the chip connected to it, returning it to a known initial state, which is very useful for debugging and testing processes.
[0030] The security chip_DM probe and security chip_DP probe are two data lines of the USB interface. The security chip_DM probe is the negative pole of the USB data line, and the security chip_DP probe is the positive pole of the USB data line. The two probes can complete the bidirectional transmission of password card test data and quality inspection data.
