Embodiment approach

[0045] As another implementation manner, the power-taking port dedicated to the power-off monitoring device is provided by a USB interface of the protected device. Conventional 5V USB interface can realize power supply. The power-off monitoring device is connected to the USB port of the protected device through the power-taking line, and the USB connection line between the protected device and the power-off monitoring device can be realized by monitoring the voltage of the USB connection in addition to physical reinforcement means. Plugging and unplugging monitoring of connecting wires.

[0046] The power-taking and connecting module may include an automatic switch, for example implemented by a relay, which is connected to the power supply line of the external protective device; when the power supply line of the external protective device is working normally, the automatic switch makes the The power-taking line is disconnected, and when the power supply line of the external p...

Abstract

The invention discloses a power-off monitoring device and method and external protection equipment. The power failure monitoring device is used for monitoring and warning abnormal power failure monitoring of external protection equipment and comprises a power taking circuit, a power taking connection module and a warning module, the power taking circuit is used for connecting the power failure monitoring device to a special power taking port, and the special power taking port is not connected to a power supply circuit of the external protection equipment; the power-taking connection module is used for monitoring whether the external protection equipment is powered off abnormally or not and connecting the power-taking circuit when monitoring that the external protection equipment is powered off abnormally, so that the power-off monitoring device is started by taking power from a special power-taking port; and the warning module is used for sending warning information when the power-off monitoring device is started. Through the mutual exclusion type power supply design, the special power taking port can be switched on to work when the external protection equipment is powered off abnormally, so that the safety problem caused by powering off the external protection equipment is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of equipment safety protection, and in particular relates to a power-off monitoring device and a power-off monitoring method for external protective equipment, as well as corresponding external protective equipment. Background technique [0002] In recent years, the development of computer and network technology has greatly promoted the popularization of the network. However, when people enjoy the convenience brought by the network, they are also facing new threats to network security and data security. Common threats include malicious code intrusion, virus / Trojan horse infection, traffic attack, hacker theft, unauthorized access, posing as a legitimate user, destroying data integrity, interfering with the normal operation of the system, using the network to spread viruses, and man-in-the-middle eavesdropping, etc. [0003] There are many technical means to solve the problem of network security or data secur...
