In the flexible regulation and control system of the external equipment, a demand acquisition module is used for configuring a matching set of service types and equipment quantity and calling a port equipment detection circuit to acquire a new equipment access state of the HUB chipset; the demand acquisition module performs data interaction operation based on the HUB chipset, the service type and equipment number matching set and the new equipment access state to obtain service demands;

specifically, the data interaction operation includes: when the new equipment access state is no new equipment access, the demand acquisition module calls the HUB chip set to acquire service information in the self-service terminal equipment; a demand acquisition module extracts the service type in the service information, and screens out demand equipment corresponding to the service type in the service type and equipment matching set; the demand acquisition module extracts first equipment information of the demand equipment and sets the first equipment information as the service demand.

In the flexible regulation and control system of the external device, a flexible power-down module is used for executing selective power-down operation according to the bound device, the unbound port and the service requirement;

specifically, the selective power-down operation includes: the flexible power-down module acquires second equipment information of the bound equipment and identifies whether the first equipment information contains equipment information which is not matched with the second equipment information; if the bound equipment does not exist, the flexible power-down module sets the bound equipment corresponding to the first equipment information matched with the second equipment information as equipment to be started; the flexible power-down module calls the HUB chipset to perform the power-down operation on the unbound port and the first port except the first port corresponding to the device to be started; if yes, the flexible power-down module calculates the required equipment number of the required equipment corresponding to the first equipment information which is not matched with the second equipment information; the flexible power-down module selects the unbound ports with the number corresponding to the number of the required devices from the unbound ports as the reserved ports; the flexible power-down module calls the HUB chip group to perform the power-down operation on the unbound ports except the reserved port;

correspondingly, a legal detection module and an illegal equipment identification set are also configured in the flexible power-down module; when a reserved port is generated in the selective power-down operation, the flexible power-down module executes security detection operation based on the illegal equipment identification set and the reserved port; the security detection operation includes: flexibly powering off the module and calling a legal detection module to acquire equipment identification information of access equipment in the reserved port; the flexible power-down module calls a legal detection module to judge whether the illegal equipment identification set has the illegal equipment identification matched with the equipment identification information; if the device identification information does not exist, the power-down module flexibly sets the reserved port corresponding to the device identification information as the first port and executes the binding step; if yes, the flexible power-down module calls the HUB chipset to give an alarm to the self-service terminal equipment.

Through the flexible regulation and control system of the external device described in this embodiment, through the mutual cooperation of the self-checking module, the binding module, the demand acquisition module and the flexible power-off module, the peripheral in the self-service terminal device can be flexibly and flexibly controlled electrically from top to bottom, and the peripheral can be further regulated and controlled according to business requirements, so that certain flexibility can be ensured, the power consumption of the self-service terminal device can be reduced, the external device which is automatically accessed by a user can be managed and controlled through final safety detection operation, the safety of the self-service terminal device is improved, and the defects of the prior art are overcome.

Example 3

The present embodiments provide a computer-readable storage medium comprising:

the storage medium is used for storing computer software instructions for implementing the flexible regulation and control method of the external device according to embodiment 1, and includes a program for executing the flexible regulation and control method of the external device; specifically, the executable program may be embedded in the flexible regulation and control system of the external device described in embodiment 2, so that the flexible regulation and control system of the external device may implement the flexible regulation and control method of the external device described in embodiment 1 by executing the embedded executable program.

Furthermore, the computer-readable storage medium of the present embodiments may take any combination of one or more readable storage media, where a readable storage medium includes an electronic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination thereof.

Different from the prior art, the method, the system and the medium for flexibly regulating and controlling the external equipment can flexibly control the external equipment on the self-service terminal to be powered on and powered off through the method, the port can be reserved for the external equipment according to the business requirement, unnecessary external equipment is powered off according to the business requirement, the external equipment which is automatically accessed by a user is subjected to legality detection, effective technical support is provided for the method through the system, the flexibility and the safety of the method are extremely high, the operation is simple, the defects of the prior art are overcome, and the method has extremely high market value.
