Embodiment Construction

[0024] Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. However, those skilled in the art will know that these specific examples are only for the convenience of understanding the present invention, rather than limiting the present invention.

[0025] According to the general standard of USB peripherals, as shown in Figure 1(a), for low-speed USB peripherals (for example, USB1.0), in the idle connection state of USB peripherals, for example, USB peripherals 10 are connected to (host controller 20), the pull-up resistor R3 (for example, 1.5K) on the D- line pulls up the voltage on the pull-down resistor R2 (for example, 15K), so that the D- line maintains a high level, and the D+ line stay low. For high-speed USB peripherals (for example, USB1.1), as shown in FIG. 1(b), when the USB peripheral 10 is connected to the host controller 20 of the PC, the pull-up resistor R4 ( For example, 1.5K) pulls up the vo...

Abstract

The invention discloses a peripheral device detection device, which includes a filtering unit for filtering the signal from the peripheral device bus to obtain an idle signal; and a detection unit for detecting the peripheral device according to the obtained idle signal Set connection status. Compared to existing solutions in the field such as contactless smart cards and mechanical solutions, the present invention is not only simple / low cost, but it is an effective asset management method and can send an alarm signal to the controlling PC or server, allowing IT staff is aware of the alert in a timely manner. The present invention is effective in various states of the computer. If the capacity exceeds 100K, the additional cost will be very low. An obvious advantage of the present invention is that there is no need to redo the USB peripherals, only the motherboard. Furthermore, the invention is applicable to protect all USB peripherals (low speed / high speed).

Description

technical field [0001] The present invention relates to computer hardware management. In particular, the present invention relates to a peripheral device detection device, a computer and a computer network using the peripheral device detection device, and a peripheral device detection method. Background technique [0002] At present, there is an urgent need for anti-theft and effective asset management of various USB peripheral computer peripherals such as keyboards, mice, and network cameras. At present, there are two traditional methods in terms of peripheral anti-theft, one is the mechanical method, and the other is the non-contact intelligent detection method. However, these two methods not only have high cost, but also cannot send alarm information to the main control device in real-time or in each working state of the computer (for example, S0-S5), and cannot realize remote management. Contents of the invention [0003] To solve the above problems in the prior art,...
