In described step 20, window background adopts engineering site picture.This technology adopts system model window to adopt engineering site figure sheet mode, but can solve, one of current active audio amplifier control field is important but to be solved under the audio amplifier remote control manipulation and managerial efficiency that limits to cause due to passing experience and conventional thought, and problem not easy to identify is located by audio amplifier model layout.

The control software of current most of active audio amplifier is still continued to use the control model of the digital audio processor list formula of former external, if need the audio amplifier of control more, when sound system is more complicated, the control model of this list formula is easy to occur the problem of target control object deviation.So-called target control object deviation refers to, that for example entity audio amplifier first is corresponding is audio amplifier model A, but technical staff thinks that in the upper operation mistiming of main control system (or claiming to control platform) audio amplifier Model B is the diaphone box model of entity audio amplifier first, thereby the DSP data to audio amplifier model are edited, the entity audio amplifier first that the entity audio amplifier of DSP data is revised in now actual quilt control and non-technical personnel is contemplated or estimate, thus there is target control object deviation.

Original this deviation is avoidable, also adopted in the prior art multiple technologies means to ensure which entity audio amplifier of the audio amplifier model corresponding engineering site of technical staff in can discrimination system model, but these means are the visual RM of right and wrong mostly, in duration anxiety, the occasion that debugging task is heavy, these distinguish that means still can expend the more time and efforts of technical staff, and efficiency is not high and easily make mistakes.

The background of system model window can be arranged to engineering site picture, technical staff can be placed on the audio amplifier icon in system model on the installation site of correspondent entity audio amplifier in engineering site picture, audio amplifier icon in system model is distributed and more approach the deployment scenarios of entity audio amplifier, technical staff can be associated fast, accurately identify the entity audio amplifier of which position in the corresponding engineering site of each audio amplifier icon (audio amplifier model), shorten the time of finding the audio amplifier model corresponding with entity audio amplifier, not only can accelerate the efficiency of sound box system debugging control, can also improve the accuracy of entity audio amplifier control, effectively avoid because of the entity audio amplifier target control object offset issue due to human negligence.

In described step 20, described Auto-matching operation comprises: main control system obtains the current sequence number that is connected entity audio amplifier with main control system by mixed-media network modules mixed-media search;

Judge in the audio amplifier model of current system model whether have the audio amplifier model that comprises this sequence number, if without completing automatic matching operation; If have, carry out DSP data checks and data simultaneous operation;

Check that whether the DSP data of this audio amplifier model are identical with the DSP data of this entity audio amplifier, if the identical automatic matching that completes of both DSP data operates, if both DSP data are not identical, executing data simultaneous operation, and by user select be by the DSP data Replica of audio amplifier model to entity audio amplifier or by the DSP data Replica of entity audio amplifier to audio amplifier model.

In described step 41, can create in the following manner audio amplifier model (creating off-line audio amplifier model):

Display device storehouse on the display interface of display module, equipment library can in comprise the audio amplifier model icon corresponding with default model audio amplifier (can show with list or icon form), from equipment library, select audio amplifier model icon;

Selected audio amplifier model icon is dragged and dropped in system model window, and creates the audio amplifier model object (specifically audio amplifier model picture corresponding audio amplifier model data be saved in audio amplifier model object) corresponding with this audio amplifier model icon in data module.

In described step 41, can also create in the following manner audio amplifier model (creating online audio amplifier model):

On the display interface of display module, show online equipment library, in online equipment library, comprise online audio amplifier mark or icon, each online audio amplifier mark or icon represent that one is set up with main control system the entity audio amplifier that network is connected, and selects online audio amplifier icon from online equipment library;

Selected online audio amplifier icon is dragged and dropped in system model window, and in data module, creates audio amplifier model object;

The sequence number of the corresponding entity audio amplifier of this online audio amplifier icon is saved in this audio amplifier model object.

For the audio amplifier model of carrying out matching operation, connect with entity audio amplifier and the main control system of this audio amplifier model pairing if current, defining this audio amplifier model is online audio amplifier model.For online audio amplifier model, if user revises the DSP data (icon of clicking this online audio amplifier model can enter the DSP data modification page) of this online audio amplifier model, synchronous executing data upgrades operation, send in pairing entity audio amplifier by the mixed-media network modules mixed-media of main control system by amended DSP data, the DSP data that are equivalent to amendment come into force to pairing entity audio amplifier immediately, make user to carry out real-time debug correction or adjustment to sound system.

With online audio amplifier model accordingly, for the audio amplifier model of not yet carrying out matching operation, though or once carried out matching operation, the entity audio amplifier of pairing is current with it is not connected with main control system, is defined as off-line audio amplifier model.For the DSP data of off-line audio amplifier model modification, cannot instantaneous transmission to corresponding entity audio amplifier, but can after reloading the success of initialization Auto-matching, by the data method of synchronization, amended DSP data be sent in corresponding entity audio amplifier by system next time.

In addition, consider aims of systems user group and sound field forecast analysis software object user group's difference, audio amplifier control system generally lays particular emphasis on auxiliary management, and system can not design too complicatedly, simple, directly perceived, easily operation is the major criterion of this class control system.Therefore audio amplifier control system generally can integrated virtual audio analyser function, in the time that needs are debugged sound system, can only be undertaken by the audio analyzer of entity.If debugging, tester leave engineering site, system debug work cannot be proceeded.

Secondly, sound system design is carried out system modelling harmony field prediction with sound field forecast analysis software conventionally, this class software is generally accompanied with virtual audio analyzer function, can predict by insert the mode of virtual speaker in three-dimensional or two-position system model the sound effect of the specified point of sound reinforcement system.The analytical effect of its acquisition similar with the measurement microphone that is connected to entity audio analyzer is placed into the assigned address of engineering site after measure by entity audio analyzer the effect obtaining.Therefore in the time carrying out sound system design, (mainly refer to sound equipment layout), can adjust distribution of sound box and concrete position design by this virtual audio analyser function, thereby improve accuracy and the science that sound system designs.But due to the actual audio amplifier DSP data of engineering site may through can through artificial adjust or when dispatching from the factory individual data items there are differences, therefore forecast analysis software cannot obtain these data, thereby also cannot carry out sunykatuib analysis by self subsidiary virtual audio analyser function.

Generally speaking, audio amplifier control software cannot carry out the sound system debugging of " off-line " because a variety of causes does not possess virtual audio analyser function, and though sound field hypothesis analysis system possesses virtual audio analyzer, but but cannot carry out simulative debugging owing to cannot obtaining the audio amplifier DSP data of engineering site reality, moreover be can simulative debugging, the audio amplifier DSP data after debugging also cannot be given to audio amplifier control system and proceed debugging operations in kind.Therefore get through this two systems, can hold for the sound system debugging in sound system design in early stage and later stage provides more branched, thus the flexibility and the science that improve sound system design, debug, and increase work efficiency.

(2) the selected selected audio amplifier illustraton of model that online audio amplifier identifies or icon is dragged and dropped in system model is put on, automatically triggered and judge whether to carry out matching operation with this;

(3) if the audio amplifier model of audio amplifier model is consistent with the audio amplifier model of online audio amplifier mark or icon institute correspondent entity audio amplifier, can carry out matching operation (now whether carrying out matching operation is selected by user); If audio amplifier model is inconsistent, point out user can not carry out matching operation;

(4), if carry out matching operation, the sequence number of online audio amplifier mark or the corresponding entity audio amplifier of icon is copied in the audio amplifier model object of this audio amplifier model, thereby make to set up pair relationhip between audio amplifier entity and audio amplifier model; If execution matching operation, can select executing data simultaneous operation;

(5) data simultaneous operation, by selecting, the DSP data of audio amplifier model (being the DSP data that comprise in audio amplifier model object) are all copied to and matched with it in entity audio amplifier, or select the DSP data in this entity audio amplifier all to copy in the audio amplifier model object of the audio amplifier model matching with it.
