A grounding end of the adjustable power supply and control module is connected with a signal ground of a detected circuit board, an excitation signal output end of the adjustable power supply and control module is connected with an excitation signal input end of the detected circuit board, and a first power signal output end of the adjustable power supply and control module is connected with a power signal input end of the detected circuit board. The transparent insulating glue layer containing inorganic electroluminescent powder is adhered to the surface of the detected circuit board. A second power signal output end of the adjustable power supply and control module is connected with the transparent conductive coating layer through an electrode. A controlled alternating-current electric field can be formed between the transparent conductive coating layer and the detected circuit board. By adopting the circuit board electroluminescent detection system of the invention, the efficiency of circuit board detection and maintenance is improved.
