The invention provides a lamp signal control system for a non-volatile memory express solid state disk. The lamp signal control system comprises a non-volatile memory express solid state disk, a slave processor and a controller. The non-volatile memory express solid state disk is provided with a control module for transmitting an operation signal and a solid state disk position signal. The slave processor is electrically connected with the control module and is used for receiving the operation signal and the solid state disk signal, driving an operation indication lamp to light according to the operation signal and driving a fault indication lamp to light when detecting the fault of the non-volatile memory express solid state disk. The controller is electrically connected with the slave processor and is used for allowing a user to control the controller to drive a solid state disk position indication lamp to light.

The invention provides a method for judging the optical catastrophe type of a semiconductor laser chip, which solves the problems of high judgment cost, long judgment time and low production efficiency of existing semiconductor laser chips COBD and COMD. The method includes: Step 1, setting the loading current; Step 2, loading the loading current on the semiconductor laser chip; Step 3, collecting the current-power curve and current-voltage curve of the semiconductor laser chip; Step 4, if the current-power curve If the current-voltage curve suddenly drops and the current-voltage curve suddenly rises, it is judged that the optical catastrophe of the chip is COMD; if the current-power curve suddenly drops and the current-voltage curve suddenly drops, it is judged that the optical catastrophe of the chip is COBD. The method of the present invention does not require professional equipment, and only needs to collect the current, power value and voltage value in the test process to judge COBD and COMD. The detection equipment is simple and the cost is low, and only ordinary technicians can realize the judgment of failure .

The invention discloses an easy-maintaining pipeline electric wire. The structure of the easy-maintaining pipeline electric wire includes a power supply plug, a horizontal pipeline wire, a power socket, a vertical pipeline wire, and a grid interface; the power supply plug is fixed outside the wall through cement; and the horizontal pipeline wire is electrically connected to the right side of the power supply plug. In the case of a sudden increase of the current in the circuit and a voltage change, the shape of a magnet absorbed belt can be changed to compress a corresponding needle-nosed belt,so that the needle-nosed belt causes a stimulating slide on a rolled sheet and makes the rolled sheet carry out an action effect of the corresponding circuit, so that people can accurately determinewhich wire is faulty after removing the wire; through the collision occurrence effect of collision particles in a rotating cone and the effect of color-changing of a certain color-changing belt, the fault of a certain line can be judged visually and acoustically; and the double judgment is more accurate; therefore, the waste of maintenance time caused by misjudgment is prevented.

The invention discloses a converter circuit fault detection method, a readable storage medium and a converter. The method comprises the steps that: the step 1, a converter controller acquires a current direction variable A representing a converter output point, a current actual voltage state variable B representing the converter output point and a current semiconductor switch command C of a converter switching device; the step 2, one of the current direction variable A, the voltage state variable B and the switch command C is selected in the current direction as an object to be compared, the predicted value of the object to be compared is predicted through the other two; and the step 3, the converter controller compares the differences between the predicted value and the actual value of the object to be compared to determine the state of the converter, determines and outputs the fault of the converter when the differences are different, and determines that the converter is normal when the differences are the same. According to the method, only the variable representing the current direction and the variable representing the voltage state are required to be obtained, and the fault determination is performed by combining the switching state of the switching device, so that the calculated amount is less, the error is small, and the determination is rapid, simple and convenient.
