Description

technical field [0001] The invention relates to an intelligent method, in particular to a plug-in method for making a circuit board of a microwave instrument intelligent. Background technique [0002] Today's smart instruments generally adopt a modular design. The main control module installed with a CPU realizes the expansion of the bus slot structure through a motherboard, and other functional circuit board modules are plugged into the instrument motherboard. When the function of the instrument is upgraded or maintained, only a certain functional circuit board needs to be replaced. The frequency band of microwave instruments covers a relatively wide range. An instrument can directly range from a few Hz to tens of GHz. At the same time, it is limited by the design and processing level. The device characteristics, material characteristics, frequency characteristics, and temperature characteristics of many functional circuit boards inside it vary. Qi, the circuit boards debu...

AI Technical Summary

Problems solved by technology

[0006] 1. Unable to adapt to the characteristics of mass production and debugging of microwave instruments

[0007] The microwave instrument circuit board belongs to the distributed parameter circuit, so the circuit debugging is complicated and the cycle is long, especially in the domestic microwave instrument, in order to realize a predetermined function index in the instrument, when the circuit board of the same design is produced and debugged, it may be due to the circuit board The purchase batches of materials and devices are different, and the debugging and replacement of devices are different. The internal function details are reflected in the software of the whole machine, that is, the control method and calibration method may be different.

When the production batch is relatively large, the whole machine software cannot accommodate such uneven circuit board software

[0008] 2. Microwave instruments have a long life cycle and cannot adapt to the maintenance guarantee of after-sales service

[0009] Many microwave instrument products are measurement-grade instruments with high precision requirements. During production and debugging, many auxiliary debugging instruments are needed, and the volume and weight are relatively large. The average time between failures of general instruments is 3000 or 5000 hours. The probability of failure is relatively high. When the products sold to users fail, timely maintenance services are required. Therefore, door-to-door repairs are often required. However, when it comes to circuit boards of microwave devices, most of them cannot be solved by replacing the circuit boards on site. Because After the replacement is completed, a series of sophisticated auxiliary microwave instruments are needed to test and calibrate

Therefore, we have to return to the original factory for maintenance, and return it to the user after completion, which has caused great inconvenience to users, especially foreign users.

[0010] 3. The software of the whole machine is difficult to maintain

After the software is modified and tested, it needs to be placed on the manufacturer's website for users to download and upgrade. However, due to the inconsistency of the hardware of the previous products, it is difficult to ensure that the later software update is suitable for many previous hardware versions.
