Abstract

The invention relates to a device for monitoring the real-time running state of equipment by utilizing a USB interface and a working method of the device. The device comprises N groups of USB monitoring circuits; each group of USB monitoring circuits are connected in parallel; each group of USB monitoring circuits comprises a core circuit, and a Type-A USB 2.0 interface and a Micro _ USB 2.0 interface which are connected with the core circuit; the Type-A USB 2.0 interface is also connected with a device to be detected; the Micro _ USB 2.0 interface is also connected with an external PC (Personal Computer); and the core circuit comprises a USB 2.0 Switch chip and an indicating lamp display circuit. The USB 2.0 Switch chip is connected with the device to be detected through the Type-A USB 2.0 interface to detect the D + / D- pin level state of the USB 2.0 Switch chip, and when the device to be detected detects that D + / D- is high, the device to be detected enters a test mode; the USB 2.0 Switch chip is connected with the indicating lamp display circuit to display different test states of the device to be detected. And the USB 2.0 Switch chip is connected with the PC through the Micro _USB 2.0 interface to print a log of the device to be detected through the PC. According to the invention, an additional debugging interface is not required to be added, and the electronic equipment testing convenience is improved.

Description

technical field [0001] The invention relates to the technical field of power electronics detection, in particular to a device and a working method for monitoring the real-time running state of equipment using a USB interface. Background technique [0002] In the process of developing an electronic product, developers often need to perform long-term stress tests on the electronic product, such as placing it in an incubator for high and low temperature tests, to verify the stability of the device for a long time. It can be seen that real-time monitoring and abnormal diagnosis of equipment status are the key guarantees for the stable operation of inspection equipment. Existing monitoring technical solutions generally use the built-in indicator light or display screen on the device to visually observe the test results, or connect to the PC terminal / host computer through the serial port of the device, print out debugging information and input debugging commands, and then analyze ...
