Often, hundreds or thousands of electronic components are integrated on a circuit board, and the wiring of the circuit board is very complicated, and some circuit boards are further divided into many layers. In the process of processing signals by the circuit board, once one of the circuit nodes, such as broken wiring, damaged electronic components, and pin failure of a functional chip, affects the output result of the circuit board, such as abnormal output data. In view of the above data abnormality, even a professional of an equipment supplier has difficulty in finding out the location of a fault in a short time due to the complexity of a circuit board, and it is more difficult to solve the problem in a short time. Aiming at the problems, the invention provides a circuit board remote maintenance guarantee method and a circuit board remote maintenance guarantee system, which can quickly help field operators to accurately position the fault circuit node, quickly provide a fault solution and are beneficial to improving the maintenance efficiency of equipment.

The above-described steps S100 to S300 are basic preparation steps.
In step S100, because there is not only one signal or data output by the PCB, the circuit node faults corresponding to each abnormal data are different, and one abnormal data may correspond to each circuit node fault.

Because the generation of abnormal data can be related to a plurality of circuit nodes, in the invention, the relevance ranking between the circuit node fault and the abnormal data is carried out, and when the circuit node which is possibly faulted is detected, if the circuit node data is normal, the circuit node which is possibly faulted can be quickly switched to the next circuit node which is possibly faulted according to the prompt until the circuit node which is possibly faulted is found. According to the arrangement, the position of the next circuit node to be detected does not need to be manually judged by a field operator, so that the detection efficiency of the field operator can be effectively improved.
In detail, in the step S700, the feedback analysis result information includes a solution corresponding to the circuit node fault and circuit node fault information. Wherein the circuit node fault information is stored to a storage device. By using the technical scheme, the position information of the fault circuit node can be fed back at the first time, a proper solution is provided, and the fault information of the circuit node is stored, so that a supplier can be helped to perfect the diagnosis and elimination work of the fault of the circuit node, and the equipment supplier can be facilitated to pertinently improve the product.
