Automatic learning and detecting device and method for LED light strings

The invention discloses an automatic learning and detecting device and a method for LED light strings. The detecting device comprises a main control machine, a constant current driving source and a voltage collecting device, and the main control machine sends input configuration detecting parameters to the constant current driving source; the constant current driving source generates two sets of non-zero power supplies with different voltage values, and the two sets of non-zero power supplies are loaded into the LED light strings to be detected; the voltage collecting module collects the voltage values of the LED lamp strings to be detected, the voltage values are sent to the main control machine to perform learning parameter operations, and the main control machine performs the detectionaccording to the configuration of learning parameters. According to the achieved detecting device and detecting method, self-adaptive light string voltage values can be achieved, the cumbersome configuration of multiple param
