Abstract

The invention provides an access control device having three operating systems. The access control device comprises a first virtual machine, a second virtual machine, a third virtual machine and a system switching unit. An embedded system is running on the first virtual machine; a first backup system is running on the second virtual machine; and a second backup system is running on the third virtual machine. The first virtual machine is used for carrying out a normal system state. The second virtual machine and the third virtual machine are used for carrying out backup system states. The system switching unit is used for monitoring the states of the first virtual machine, the second virtual machine and the third virtual machine; and the system switching unit selects one virtual machine from the second virtual machine and the third virtual machine to carry out a dynamic switch with the first virtual machine when it is monitored that the first virtual machine is crashed, so as to take place of the normal system state of the first virtual machine; and the other one of the second virtual machine and the third virtual machine is utilized for recovering the first virtual machine into the backup system state. The access control device having the three operating systems is able to keep controlling the access when the operating system is crashed.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to an access control device with three operating systems. Background technique [0002] Currently, many users can use one and the same device at the same time. For example, user A can use a terminal to access a device owned by user A, and another user B can also access the device owned by user A. In situations where a user lends a device to another person over the network, security is a primary concern. When the resource providing device storing resources is allowed to be accessed from the resource accessing device through the network so that the resource accessing device can use the resource of the resource providing device, there is a case where the resource is used by a third party without the owner of the resource providing device knowing. possibility of unauthorized access. Therefore, an access control device is required to control the resource access to the resource ...
