Description
Technical Field
The application relates to the technical field of sound masking systems, in particular to an information centralization management system and method for a multi-sound masking system.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The language sound is used as an important carrier for people to exchange and transfer information, and the carried information is abundant and has more occasions. When people talk, a large amount of sound information is generated. Because the indoor facility conditions and the safety conditions are changeable, sensitive sound information can leak to different degrees, and the security of speaking content is directly related.
With the development of information technology, eavesdropping means are increasingly advanced, and serious challenges are brought to sound information security. In order to improve the sound information security, sound information leakage protection is required. In particular, it relates to a confidential place of confidential information such as national policy, military, business, science and technology, etc., and its facility condition and security status are directly related to the smooth progress of confidential activity and the security of speaking content. Currently, in order to ensure sound information security, two approaches are mainly adopted: firstly, by changing the building structure, the leakage of sound information is reduced as much as possible; secondly, by installing an acoustic masking system, the leaked acoustic information is not easy to acquire.
The sound masking system achieves the purpose of preventing eavesdropping by additionally arranging an interference device at a position where sound information leakage is likely to occur, signals generated by the existing sound masking system are converted into masking signals such as sound signals and vibration signals through devices such as a sound generator and a vibration generator, and sound information protection is carried out on a certain area.
However, the inventor finds that the current sound masking system is greatly influenced by hardware design and specific environment system layout, and effective protection can not be carried out by infinitely increasing the protection terminals, so that the protection area of the single sound masking system is limited. As the number of the sound masking systems increases, the multiple sound masking systems are required to work simultaneously for protection, but as the sound masking systems work independently of each other and have no data interaction, the maintenance difficulty and the management cost increase along with the increase of the number of the sound masking systems.
Aiming at the problem of information centralization management when the existing common multi-sound masking system works cooperatively, no effective solution is proposed at present.
Disclosure of Invention
In view of this, the application provides a system and a method for information centralization management of a multi-sound masking system, which classifies the data information of all the sound masking systems and classifies the data information in a class, thereby greatly reducing the maintenance difficulty and the management cost when the sound masking systems are operated.
According to a first aspect of an embodiment of the present application, there is provided a multi-sound masking system information centralization management system including: the system comprises a controller, an information centralization management device and at least two sound masking systems respectively connected with the information centralization management device, wherein each sound masking system comprises a sound masking system controller and at least one sound masking system load connected with the sound masking system controller;
the information centralization management equipment carries out parameter configuration on each sound masking system by receiving a controller instruction;
and receiving the working state data uploaded by each sound masking system, classifying the working state data, and sending the working state data to the controller according to the priority level of each data classification.
According to a second aspect of the embodiment of the present application, there is provided a method for centrally managing information of a multi-sound masking system, including:
generating an initial equipment list, an initial theoretical configuration information list, a corresponding protection area diagram and a protection parameter description according to the arrangement condition of each sound masking system;
acquiring identifier information of each current sound masking system to form a current equipment list, and updating an initial equipment list according to the current equipment list;
parameter configuration is carried out on each sound masking system;
and receiving the working state data uploaded by each sound masking system, classifying the working state data, and uploading the data according to the priority level of each data classification.
Compared with the prior art, the application has the beneficial effects that:
(1) The application can flexibly expand according to the size of the protection area, and realizes the collaborative protection of the multi-sound masking system. Because the protection area of a single sound masking system is limited, when the protection area is increased and two or more sound masking systems are required to be protected, infinite expansion of the protection area of the system can be realized through the star-shaped expansion structure. The method can conveniently acquire the protection parameters of the area to be protected and flexibly configure the number and the positions of the sound masking systems.
(2) The multi-sound masking system is more convenient to maintain during collaborative protection, simpler to manage and lower in management cost. The parameter configuration and terminal data centralized management and monitoring during multi-system protection can be realized through the information centralized management method, and the effective supervision of the running states of each sound masking system and the working states of the vibration masking device and the sound masking device which are correspondingly installed are realized. The fastest, most efficient and most accurate equipment maintenance and management is realized.
Additional aspects of the application will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the application.
