Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of nixie tube control, especially relates to a nixie tube module without data interface. BACKGROUND
[0002] Nixie tubes (also known as digital display tubes) are widely used in various electronic products, such as home appliances, instruments and meters, automotive electronics, electronic watches, etc., for displaying digital information. A nixie tube module typically consists of a nixie tube display assembly and a driving circuit, and its working principle is to display numbers by controlling the on-off of different segments of LED or LCD displays.
[0003] With the popularity of smart devices and embedded systems, the application field of nixie tube modules is increasingly expanding, and higher requirements are put forward for their performance and use convenience. Traditional nixie tube modules mostly rely on data interfaces (such as serial ports, parallel ports, or I2C interfaces) to communicate with controllers. Although this design pattern can achieve the function of digital display, it also faces certain limitations and deficiencies.
[0004] 1. Complexity of data interface: Existing nixie tube modules usually need to be controlled through standard data interfaces (such as serial ports, parallel ports, I2C, etc.). This not only requires the control system to have certain hardware interface support, but also may increase the complexity and cost of system design. Especially in embedded systems, there are usually limited IO port resources, and the use of data interfaces limits the expansion of other functions.
[0005] 2. Increased system burden: Traditional nixie tube modules need to send a large amount of control data through data interfaces. Especially when complex information or dynamic changes need to be displayed, frequent data transmission will increase the burden of the processor, which may cause system response delay or resource waste.
[0006] 3. Interface compatibility problem: Different nixie tube modules may use different types of data interfaces, which brings compatibility problems to system integration. Especially when different models or brands of nixie tube modules need to be controlled uniformly, the differences in interfaces may affect the stability and expandability of the system.
[0007] 4. Occupying physical interface resources: Data interfaces usually occupy physical interface resources of the system, especially in high-density embedded systems, each interface needs to occupy space on the board, which may cause waste of resources and limit the optimization and compact design of the system.
[0008] 5. Low flexibility: The traditional control mode of nixie tube modules is usually fixed, and needs to be programmed and debugged for different display modes or information. If the system requirements change, it may be very tedious to modify the control program of the data interface and not easy to adjust flexibly.
[0009] Therefore, the working principle and control mode of the traditional nixie tube module are not efficient and flexible in some application scenarios, and an innovative solution that can simplify the control process, reduce the occupation of physical interfaces, improve the overall performance and compatibility of the system is urgently needed.

[0014] Further, the nixie tube is connected with a nixie tube driving chip, and the nixie tube driving chip drives the nixie tube to display according to the control signal output by the decoding adjustment module or the MCU.
[0015] Preferably, the feedback power supply chip adopts an FM25XX series chip.
[0016] Preferably, the nixie tube driving chip adopts TM1616.
[0017] Preferably, the nixie tube driving chip is connected with four nixie tubes.

[0019] 1. Without data interface, the system design is simplified
[0020] The nixie tube module provided by the utility model does not depend on data interface, and realizes digital display directly through simplified circuit design and control mode. This greatly simplifies the system design, not only reduces the demand of interface hardware, but also reduces the complexity of system integration.
[0021] 2. Save physical interface resources
[0022] Since the present invention does not use a data interface, it reduces the occupation of IO ports or other physical interfaces. This is particularly beneficial for embedded systems with limited hardware resources, freeing up more resources for other functional modules and improving the scalability and flexibility of the system.
[0023] 3. Reduce processor burden
[0024] In traditional digital tube modules, data transmission requires a large amount of computing and communication resources. Frequent data updates increase the processor burden, especially when displaying dynamically changing numbers. However, the present invention avoids data transmission through a data interface and directly controls the digital tube display, reducing processor requirements, lowering system burden, and improving response speed.
[0025] 4. Compatibility enhancement
[0026] Traditional digital tube modules may have compatibility issues due to interface differences. However, the present invention eliminates this problem through a design without a data interface, making the digital tube module more easily compatible with different types of control systems, especially in applications between different devices and systems, with greater versatility.
[0027] 5. Improve flexibility and maintainability
[0028] By eliminating the complex control of the data interface, the utility model makes the control of the digital tube more direct and flexible. Users can more conveniently configure, adjust and maintain the module without worrying about complex data communication protocols or hardware interface compatibility issues, thereby improving the operability and maintainability of the system.
[0029] 6. Improve reliability
[0030] Traditional digital tube modules rely on complex interfaces and data transmission, which can lead to system problems such as communication errors, signal interference, or interface incompatibility. The design without a data interface reduces this complexity, lowers the probability of failure, and thus improves the overall reliability of the system.
[0031] In general, the present invention simplifies system design, reduces costs, and improves system compatibility and flexibility by removing the data interface, overcoming the shortcomings of traditional digital tube modules in interface usage, resource occupation, and burden, and has significant advantages.
