Detailed Description
In order to better understand the above technical solution, exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the application to those skilled in the art.
Example 1
The embodiment of the application discloses a distributed control method for a sound mixing console, and referring to fig. 1, the distributed control method for the sound mixing console comprises the following steps:
step S100, receiving a start data request when the first MCU module is powered on, and acquiring the power-on condition of the DSP module;
in this embodiment, the distributed control method for a sound mixing console includes a plurality of MCU modules, wherein the MCU modules mainly include a first MCU module, a second MCU module, and a third MCU module, and each MCU module communicates a processing result with other MCU modules using UART interfaces. Further, each MCU module is also connected with a DSP module respectively and is integrated on a complete machine device, and the first MCU module is used as a core control module of the complete machine device, has the advantages of small volume and complete and independent functions, and weakens the control force of the start data of the sound console in the system level computer.
Specifically, when the first MCU module and other MCU modules perform data interaction, the first MCU module is also connected with an external display control interface, so that information interaction is realized.
When the first MCU module is electrified, the first MCU module receives a power-on starting data request and acquires the power-on condition of the DSP module.
Step S200, acquiring a communication interface state in a preset time of a power-on condition, and acquiring a corresponding BOOT file according to the starting data request;
in some embodiments, the preset time may be 0.1ms-1s, specifically, may be 0.1ms, 0.2ms, 0.3ms, 0.5ms, 1ms, 2ms.
Further, referring to fig. 2, step S200 further includes:
step S201, counting whether the state of the communication interface is normal, and taking the abnormal communication interface as a risk communication point;
the communication interface state is a factor affecting whether the sound console can be effectively controlled, whether the conditions of the communication interface states are normal or not is counted and judged, when abnormal level signals are detected, the communication interface is judged to be abnormal, and at the moment, the first MCU module can automatically mark the communication interface as a risk communication point according to preset marking behaviors.
Step S202, outputting communication abnormality prompt information related to the risk communication points to a control interface of a system level computer;
because the abnormal communication interface is detected through statistics and the tracking mark is a risk communication point, communication abnormality prompt information related to the risk communication point needs to be output and fed back to the control interface of the system level computer, so that a user can perform previous pretreatment on the abnormal communication interface before controlling the sound console, and effective guarantee is provided for the follow-up accurate control of the sound console.
Step S203, when the states of the communication interfaces are all normal, acquiring the corresponding BOOT file according to the start data request.
When it is counted that all the communication interfaces are in normal states, for example, it is counted that level signals fed back by all the communication interfaces are valid, it is judged that all the communication interfaces are in a state capable of working normally, and at this time, the first MCU module obtains a BOOT file transmitted from the communication interfaces according to a start data request.
Step S300, downloading the BOOT file to a DSP module, analyzing the BOOT file and generating an associated data file to be stored, wherein the data file to be stored comprises an initialization program file, a memory management program file, a peripheral configuration program file and an application loader file;
further, referring to fig. 3, step S300 specifically further includes:
step S301, converting the BOOT file into different function codes to obtain a function executable program file;
specifically, the BOOT file is executed when the first MCU module is powered on, the hardware needs to be initialized in advance and a stack is prepared, and then the kernel is loaded and necessary parameters are transferred to the kernel, so that the kernel is convenient to start, and therefore, the BOOT file needs to be converted into different functional codes to obtain a functional executable program file.
Step S302, the function executable program file is packaged according to the program association structure to obtain the data file to be stored.
In some embodiments, the function executable program files are provided with a preset program association structure, so that the function executable program files are independently packaged, and the function executable program files are packaged through the program association structure to obtain the data files to be stored in consideration of accurate operation and maintenance when the function executable program files encounter a bug in operation. The data files to be stored comprise an initialization program file, a memory management program file, a peripheral configuration program file and an application loader file.
Step S400, storing the associated initialization program file, memory management program file, peripheral configuration program file and application loading program file into a readable storage space of a DSP module according to a preset distributed rule;
further, referring to fig. 4, step S400 specifically further includes:
step S401, dividing the readable storage space into a plurality of storage layers according to a preset distributed rule, wherein each storage layer comprises a plurality of storage units;
step S402, coding each storage layer marking layer;
step S403, setting a unit address code for a storage unit of each storage layer;
in some alternative embodiments, in order to improve the processing efficiency of the DSP module, the readable storage space may be divided according to a preset distributed rule, where the unit address code of each storage unit has uniqueness. Specifically, the readable storage space is divided into a plurality of storage layers, each storage layer includes a plurality of storage units, each storage layer is provided with a layer code according to a coding rule, for example, the layer code of a first storage layer may be set to a, the layer code of a second storage layer may be set to B, and the layer code of a third storage layer may be set to C. The cell address code is then set according to the memory cells of each memory layer, e.g., the cell address code of the first memory cell of each memory layer may be set to 1, the cell address code of the second memory cell of each memory layer may be set to 2, and the cell address code of the third memory cell of each memory layer may be set to 3. Finally, a file storage path can be determined according to the layer code and the unit address code, for example, the storage units of the first storage layer can be A1, A2 and A3 respectively in sequence; the storage units of the second storage layer may be B1, B2, and B3, respectively, and the storage units of the third storage layer may be C1, C2, and C3, respectively.
Step S404, according to the layer code and the unit address code, storing the associated initialization program file, memory management program file, peripheral configuration program file and application loader file into a readable storage space of the DSP module.
And storing the associated initialization program file, memory management program file, peripheral configuration program file and application loading program file into a readable storage space of the DSP module according to the layer code and the unit address code.
Step S500, analyzing each part of the associated initializing program file, memory management program file, peripheral configuration program file and application loading program file, and starting a corresponding target running mechanism;
further, referring to fig. 5, after step S404, before step S500, the method further includes:
step S501, traversing the readable storage space by adopting a traversing algorithm;
in this embodiment, because the preset distributed rule stores the associated initialization program file, memory management program file, peripheral configuration program file and application loader file in any storage unit in the readable storage space of the DSP module, before the analysis operation, the readable storage space needs to be traversed.
Specifically, after traversing, step S502 is performed, where the initializing program file, the memory management program file, the peripheral configuration program file and the application loading program file related to the console are obtained and screened;
step S503, analyzing and starting the corresponding target running mechanism.
Specifically, after the screening is obtained, each related initializing program file, memory management program file, peripheral configuration program file and application loading program file are analyzed, and a corresponding target running mechanism is started.
And step S600, when a data execution instruction sent by the first MCU module is received, the target running mechanism execution program and the data parameters are run according to the data execution instruction, the digital sound console is driven to enter a default working mode, and scene data is uploaded after the system-level computer is started.
Further, referring to fig. 6, step S600 further includes:
step S601, analyzing the data execution instruction to obtain access control information in the data execution instruction;
step S602, controlling the target running mechanism to execute a program and data parameters according to the access control information.
In some optional embodiments, when the step is ready to run, after receiving a data execution instruction sent by the first MCU module, reading and analyzing access control information carried by the data execution instruction, specifically, when the access control information may access the initialization program file, the memory management program file, the peripheral configuration program file and the application loader file associated in the storage unit, and control the target operating mechanism to execute a program and data parameters according to the access control information, so as to drive the digital tuning console to enter a default working mode, and upload scene data after the system-level computer is started.
In some embodiments, the step S600 further includes, while being executed:
step S700, when an electric push control instruction sent by a second MCU module is received, controlling a plurality of electric clippers according to the electric push control instruction, and further controlling corresponding volume and volume balance;
in some alternative embodiments, the second MCU module is configured to control the movement of the position of the electric clipper and detect the current position of the electric clipper, obtain information of the current position, generate a proportional value, send the proportional value to the first MCU module to generate a gain value, and then output the gain value to control the DSP module to make a corresponding driving signal, so as to control the corresponding volume and volume balance.
Step S800, when receiving an indication control instruction sent by the third MCU module, controlling all switch keys and indication LED lamps according to the indication control instruction.
In some alternative embodiments, the third MCU module is not only used to detect the state of a key, for example, to send an instruction to turn on an LED light by pressing a switch key, but also to send display information to an associated display module, for example, a control interface of an external system level computer, or an OLED display screen, etc.
In other words, each MCU module executes a section of function code, and different MCU modules execute different function codes; the plurality of MCU modules synchronously execute the functional codes.
In summary, the technical solution provided in the first embodiment of the present application has at least the following beneficial effects:
receiving a start data request when the first MCU module is powered on, and acquiring the power-on condition of the DSP module; acquiring a communication interface state in a preset time of a power-on condition, and acquiring a corresponding BOOT file according to the starting data request; and downloading the BOOT file to a DSP module, driving the digital sound console to enter a default working mode, uploading scene data after the system-level computer is started, and at the moment, not interrupting the operation of the sound console, wherein the starting time is reduced to 3s from the original 30 s. That is to say, by changing the starting mode of the DSP module, a single chip microcomputer replaces the operation of a system level computer, weakens the control force of the system level computer on the whole key part, solves the technical problems of slow starting and poor reliability, and realizes the most basic control when the touch screen computer is halted, thereby ensuring the technical effect of safety.
