Abstract

The invention provides a U-shaped sensor detection apparatus comprising a direct-current power supply, a detection circuit and a sensor connecting unit. The sensor connecting unit consists of a first sensor interface, a second sensor interface, and a third sensor interface; and the detection circuit includes a first light-emitting diode, a second light-emitting diode and a not-gate circuit including a first inverter and a second inverter. The first sensor interface is connected to the negative electrode of the direct-current power supply. The second sensor interface is successively connected in series with the first inverter and the first light-emitting diode and then is connected to the negative electrode of the direct-current power supply; the second sensor interface is successively connected in series with the first inverter, the second inverter, and the second light-emitting diode and then is connected to the negative electrode of the direct-current power supply; and the second sensor interface is also connected to the positive electrode of the direct-current power supply by a first resistor. And the third sensor interface is connected to the positive electrode of the direct-current power supply. The provided sensor detection apparatus has the simple structure.

Description

technical field [0001] The invention relates to a sensor detection device, in particular to a relatively simple U-shaped sensor detection device and a U-shaped sensor detection method. Background technique [0002] The existing U-shaped sensor detection method is mainly to detect the deposit and withdrawal machine where the U-shaped sensor is located. This detection method needs to power on the whole deposit and withdrawal machine first, and then start the operating system and some software for detection. This detection method is complex in operation and needs to waste detection time, and this detection method must occupy the entire deposit and withdrawal machine. Contents of the invention [0003] The object of the present invention is to overcome the above defects, and provide a relatively simple U-shaped sensor detection device and a U-shaped sensor detection method. [0004] A U-shaped sensor detection device includes a DC power supply, a detection circuit and a sens...
