It is obvious that the drawings in the following description are only some examples of the invention, and that for a person skilled in the art, other drawings and embodiments can be derived from them without inventive effort.
In one embodiment of the present invention, as shown in fig. 1, a sensor data acquisition method includes:
s100, the CPU acquires a communication interface between the CPU and the ADSP subsystem according to the acquisition instruction;
s200, after the CPU and the ADSP subsystem establish communication connection through the communication interface, the ADSP subsystem starts the performance, identifies the sensor label in the acquisition instruction, and opens the target sensor;
and the S300ADSP subsystem acquires the raw data in the target sensor and sends the raw data to the CPU.
Specifically, in this embodiment, a user can obtain raw data of the sensor through an intelligent terminal, for example, a mobile phone, a tablet, and other devices, and for example, issue a corresponding obtaining instruction through a mobile phone APP. And a user opens a corresponding operation interface on the intelligent terminal, and selects a sensor label corresponding to a target sensor which wants to acquire the original data, the type of the original data which wants to acquire and the number of the original data which is transmitted and displayed during acquisition through touch operation.
For example, when the target sensor selected by the user is a light sensor, the corresponding original data is light sensation information, the number of the transmitted data is 1, the display interface of the intelligent device displays the 1 light sensation data, and continuously updates new light sensation data in real time along with time, that is, the display interface always displays the light sensation data at the current moment. When the target sensor selected by the user is a gyroscope, the corresponding original data is X-axis, Y-axis and Z-axis coordinate information, the number of the transmitted data is 3, the display interface of the intelligent device displays the 3 coordinate data in the same row, and continuously updates new coordinate data in real time along with time, namely the display interface always displays the coordinate data at the current moment.
When a user inputs an acquisition instruction through the intelligent terminal, the sensor label corresponding to a target sensor in the acquisition instruction, the type of original data to be acquired and the number of the original data to be transmitted and displayed during acquisition can be automatically matched according to a preset configuration table. Each sensor in the configuration table corresponds to a corresponding sensor label, a type of original data to be acquired, and the number of original data to be transmitted and displayed during acquisition.
For example, in the configuration table, the sensor number corresponding to the optical sensor is 01, the type of the raw data to be acquired is light sensation data, and the number of the raw data to be transmitted and displayed is 1, so that when the optical sensor input by a user on the display interface of the intelligent terminal is the target sensor, the corresponding sensor number, the type of the raw data to be acquired, and the number of the raw data to be transmitted and displayed during acquisition are automatically acquired according to the configuration table.
Based on the preset configuration table, a user only needs to select the target sensor, other information does not need to be set one by one, operation is simplified, matched knowledge points needing to be memorized and mastered by the user are reduced, and the method is convenient and fast.
In addition, the relevant information in the acquisition instruction can be freely set by the user, or the user can change the relevant information according to the self requirement after acquiring the corresponding information according to the preset configuration table. For example, the sensor number corresponding to the gyroscope in the configuration table is 02, the type of the raw data to be acquired is X-axis, Y-axis and Z-axis coordinate information, and the number of the raw data to be transmitted and displayed is 3, so that when the user inputs the optical sensor on the display interface of the intelligent terminal as a target sensor, the sensor number corresponding to the optical sensor, the type of the raw data to be acquired, and the number of the raw data to be transmitted and displayed during acquisition are automatically acquired according to the configuration table, but the user only needs to acquire the Z-axis coordinate information according to the user's own needs, and then the type of the corresponding acquired raw data and the number of the raw data to be transmitted and displayed during acquisition can be changed, and in addition, other configuration data of the acquisition sensor, such as power consumption and the like, can be added to the type of the acquired raw data.
And a user inputs an acquisition instruction through the intelligent terminal, triggers the acquisition instruction to be sent to the CPU, acquires a communication interface between the CPU and the ADSP subsystem according to the acquisition instruction, and establishes communication connection between the CPU and the ADSP subsystem.
The get instruction and the callback function are passed to the CPU, followed by a start enable (sensor _ open). The CPU transmits the acquisition instruction to the ADSP subsystem through the established communication interface, and the ADSP subsystem identifies the sensor label in the acquisition instruction to determine the corresponding target sensor. The sensor label corresponds to the corresponding sensor uniquely, and the target sensor which the user wants to acquire the original data can be uniquely determined according to the sensor label.
The corresponding relation between the sensor labels and the corresponding sensors can adopt uniform labels in the industry, the universality is higher, the universal adaptability is realized, and the learning and the grasping of maintenance workers are more facilitated. Meanwhile, the privacy data can be set respectively based on the requirements of each manufacturer system, so that the confidentiality is enhanced, and the privacy data is prevented from being revealed.
And after the ADSP subsystem determines the target sensor, the target sensor is turned on through a corresponding interface. And then identifying the type of the original data to be acquired in the acquisition instruction and the number of the original data to be transmitted and displayed during acquisition, acquiring corresponding data through a target sensor according to the type and the number of the original data to be acquired, then sending the corresponding data to the ADSP subsystem, and sending the corresponding data to a callback function of the CPU through the ADSP subsystem. And the intelligent terminal reads the original data acquired in the callback function of the CPU and displays the original data according to a preset display mode.
According to the invention, a user can select and generate a corresponding acquisition instruction through the intelligent terminal to acquire the original data of the target sensor, and then the required original data is displayed according to a preset display mode, so that the user can acquire the original data conveniently, and the user can know information such as the working state of the target sensor conveniently so as to debug the target sensor. On the other hand, corresponding original data can be selected and displayed in a targeted mode, and interference of irrelevant data is reduced.
Another embodiment of the present invention is a preferable embodiment of the above-mentioned embodiment, as shown in fig. 2, including:
s100, the CPU acquires a communication interface between the CPU and the ADSP subsystem according to the acquisition instruction;
the step of starting the communication between the S200CPU and the ADSP subsystem through the communication interface, wherein the ADSP subsystem identifies the sensor label in the acquisition instruction, and the step of opening the target sensor specifically comprises the following steps:

the S230ADSP subsystem acquires the starting result of the target sensor and returns the starting result to the callback function of the CPU;
and the S300ADSP subsystem acquires the raw data in the target sensor and sends the raw data to the CPU.
Specifically, in this embodiment, a user can obtain raw data of the sensor through an intelligent terminal, for example, a mobile phone, a tablet, and other devices, and for example, issue a corresponding obtaining instruction through a mobile phone APP. And a user opens a corresponding operation interface on the intelligent terminal, and selects a sensor label corresponding to a target sensor which wants to acquire the original data, the type of the original data which wants to acquire and the number of the original data which is transmitted and displayed during acquisition through touch operation.
The related information in the acquisition instruction can be freely set by a user, and external data acquired by each sensor can be selected to be acquired, for example, the optical sensor acquires light sensation information, the gyroscope acquires position information of an X axis, a Y axis and a Z axis, and in addition, other configuration data of the acquisition sensor, such as power consumption, can be added to the type of the acquired raw data.
And a user inputs an acquisition instruction through the intelligent terminal, triggers the acquisition instruction to be sent to the CPU, acquires a communication interface between the CPU and the ADSP subsystem according to the acquisition instruction, and establishes communication connection between the CPU and the ADSP subsystem.

The intelligent terminal can use a plurality of prompting modes to report errors, such as voice prompt, light prompt, vibration prompt and text prompt. Meanwhile, the reason of the starting failure of the target sensor can be further displayed, for example, the target sensor corresponding to the sensor label does not exist, the interface corresponding to the target sensor does not exist under the ADSP subsystem, and the like.
The target sensor is in a closed state before a user sends an acquisition instruction, so that energy consumption is saved, and excessive data acquisition is avoided to increase storage and cache pressure. The sensor label corresponds to the corresponding sensor uniquely, and the target sensor which the user wants to acquire the original data can be uniquely determined according to the sensor label.

And the intelligent terminal reads the original data acquired in the callback function of the CPU and displays the original data according to a preset display mode.
The target sensor is started according to the starting instruction in the acquisition instruction issued by the user, and the starting result is returned to the intelligent terminal. If the starting fails, the user can quickly locate the fault step and the fault reason and take corresponding measures to solve the problem.

And then triggering the acquisition instruction to send to the CPU, acquiring a communication interface between the CPU and the ADSP subsystem according to the acquisition instruction, and establishing communication connection between the CPU and the ADSP subsystem.
The get instruction and the callback function are passed to the CPU, followed by a start enable (sensor _ open). The CPU transmits the acquisition instruction to the ADSP subsystem through the established communication interface, the ADSP subsystem identifies the sensor label and the starting instruction in the acquisition instruction, determines the corresponding target sensor according to the sensor label, and starts the target sensor through the corresponding interface in the ADSP subsystem according to the starting instruction.
The target sensor sends the starting result of the target sensor to the ADSP subsystem, the ADSP subsystem sends the callback function to the CPU, and the intelligent terminal obtains the starting result of the target sensor by calling the callback function. And if the starting result is that the target sensor is successfully started, further acquiring the original data of the target sensor according to the acquisition instruction. If the starting result is that the target sensor fails to be started, the subsequent process is terminated, the intelligent terminal reports an error, and the user is prompted that the target sensor can fail to be started.
When the starting result of the target sensor in the CPU callback function is successful, namely the ADSP subsystem successfully opens the target sensor through the corresponding interface, the type of the original data which the user wants to obtain in the acquisition instruction and the number of the original data which are transmitted and displayed during acquisition are identified, corresponding data are acquired through the target sensor according to the type and the number of the original data which the user wants to obtain, then the acquisition result and the acquired original data with the corresponding number are sent to the ADSP subsystem, and the callback function is sent to the CPU through the ADSP subsystem.
And when the acquisition result in the callback function of the CPU is successful, further displaying the original data in the callback function of the CPU according to a preset mode. And when the acquisition result in the callback function of the CPU is failure, terminating the subsequent flow, and reporting an error by the intelligent terminal to prompt the user that the acquisition of the original data of the target sensor fails.
If the obtaining result in the callback function of the CPU is successful, namely the original data of the target sensor is displayed on the intelligent terminal in real time, when a user does not need to obtain the data, a closing instruction is input through the intelligent terminal, the target sensor is closed, the connection between the CPU and the ADSP subsystem is disconnected, and resources are released.
The method and the system stop acquiring the original data of the target sensor based on the closing instruction input by the user, otherwise, the intelligent terminal continuously updates the corresponding original data in real time, thereby avoiding the user from continuously acquiring the data and avoiding the adverse effect on equipment caused by excessive repeated execution of the same command.
In an embodiment of the present invention, as shown in fig. 5, an intelligent terminal 100 employs a high-pass platform architecture, which includes a CPU110, an ADSP subsystem 120, and a plurality of sensors;
the CPU110 acquires a communication interface between the CPU and the ADSP subsystem 120 according to the acquisition instruction;
the ADSP subsystem 120, after establishing a communication connection with the CPU110 through the communication interface, starts enabling, identifies a sensor label in the acquisition instruction, and turns on a target sensor, which is any one of the plurality of sensors 130;
the method specifically comprises the following steps:
the ADSP subsystem 120 receives the sensor label and the start instruction in the acquisition instruction sent by the CPU 110;
the ADSP subsystem 120 is used for identifying the sensor label and starting a target sensor corresponding to the sensor label according to the starting instruction;
the ADSP subsystem 120 acquires the starting result of the target sensor and returns the starting result to the callback function of the CPU 110;
the ADSP subsystem 120 acquires original data in a target sensor and sends the original data to the CPU110 after the target sensor is turned on;
the method specifically comprises the following steps:
the ADSP subsystem 120 receives the data type and the data number to be transmitted in the acquisition instruction sent by the CPU 110;
the ADSP subsystem 120 acquires the original data corresponding to the target sensor according to the data type and the data number;
the ADSP subsystem 120 returns the obtained result and the original data to a callback function of the CPU 110;
the ADSP subsystem 120 for turning off the target sensor according to the turn-off instruction obtained by the CPU 110;
and after the target sensor is closed, the CPU110 disconnects the target sensor from the ADSP subsystem 120, and releases resources.
Specifically, in this embodiment, a user can obtain raw data of the sensor through an intelligent terminal, for example, a mobile phone, a tablet, and other devices, and for example, issue a corresponding obtaining instruction through a mobile phone APP. And a user opens a corresponding operation interface on the intelligent terminal, and selects a sensor label corresponding to a target sensor which wants to acquire the original data, the type of the original data which wants to acquire and the number of the original data which is transmitted and displayed during acquisition through touch operation.
For example, when the target sensor selected by the user is a light sensor, the corresponding original data is light sensation information, the number of the transmitted data is 1, the display interface of the intelligent device displays the 1 light sensation data, and continuously updates new light sensation data in real time along with time, that is, the display interface always displays the light sensation data at the current moment. When the target sensor selected by the user is a gyroscope, the corresponding original data is X-axis, Y-axis and Z-axis coordinate information, the number of the transmitted data is 3, the display interface of the intelligent device displays the 3 coordinate data in the same row, and continuously updates new coordinate data in real time along with time, namely the display interface always displays the coordinate data at the current moment.
When a user inputs an acquisition instruction through the intelligent terminal, the sensor label corresponding to a target sensor in the acquisition instruction, the type of original data to be acquired and the number of the original data to be transmitted and displayed during acquisition can be automatically matched according to a preset configuration table. Each sensor in the configuration table corresponds to a corresponding sensor label, a type of original data to be acquired, and the number of original data to be transmitted and displayed during acquisition.
For example, in the configuration table, the sensor number corresponding to the optical sensor is 01, the type of the raw data to be acquired is light sensation data, and the number of the raw data to be transmitted and displayed is 1, so that when the optical sensor input by a user on the display interface of the intelligent terminal is the target sensor, the corresponding sensor number, the type of the raw data to be acquired, and the number of the raw data to be transmitted and displayed during acquisition are automatically acquired according to the configuration table.
Based on the preset configuration table, a user only needs to select the target sensor, other information does not need to be set one by one, operation is simplified, matched knowledge points needing to be memorized and mastered by the user are reduced, and the method is convenient and fast.
In addition, the relevant information in the acquisition instruction can be freely set by the user, or the user can change the relevant information according to the self requirement after acquiring the corresponding information according to the preset configuration table. For example, the sensor number corresponding to the gyroscope in the configuration table is 02, the type of the raw data to be acquired is X-axis, Y-axis and Z-axis coordinate information, and the number of the raw data to be transmitted and displayed is 3, so that when the user inputs the optical sensor on the display interface of the intelligent terminal as a target sensor, the sensor number corresponding to the optical sensor, the type of the raw data to be acquired, and the number of the raw data to be transmitted and displayed during acquisition are automatically acquired according to the configuration table, but the user only needs to acquire the Z-axis coordinate information according to the user's own needs, and then the type of the corresponding acquired raw data and the number of the raw data to be transmitted and displayed during acquisition can be changed, and in addition, other configuration data of the acquisition sensor, such as power consumption and the like, can be added to the type of the acquired raw data.
The user inputs an acquisition instruction through the intelligent terminal, triggers the acquisition instruction to be sent to the CPU110, then acquires a communication interface between the CPU110 and the ADSP subsystem 120 according to the acquisition instruction, and establishes a communication connection between the CPU110 and the ADSP subsystem 120.
The fetch instruction and the callback function are passed to the CPU110, followed by a start enable (sensor _ open). The CPU110 transmits the acquisition instruction to the ADSP subsystem 120 through the established communication interface, the ADSP subsystem 120 identifies the sensor number and the start instruction in the acquisition instruction, determines the corresponding target sensor according to the sensor number, and starts the target sensor through the corresponding interface in the ADSP subsystem 120 according to the start instruction. The sensor label corresponds to the corresponding sensor uniquely, and the target sensor which the user wants to acquire the original data can be uniquely determined according to the sensor label.
The corresponding relation between the sensor labels and the corresponding sensors can adopt uniform labels in the industry, the universality is higher, the universal adaptability is realized, and the learning and the grasping of maintenance workers are more facilitated. Meanwhile, the privacy data can be set respectively based on the requirements of each manufacturer system, so that the confidentiality is enhanced, and the privacy data is prevented from being revealed.
The target sensor sends the self starting result to the ADSP subsystem 120, then the ADSP subsystem 120 sends the callback function of the CPU110, and the intelligent terminal obtains the starting result by calling the callback function. And if the starting result is that the target sensor is successfully started, further acquiring the original data of the target sensor according to the acquisition instruction. If the starting result is that the target sensor fails to be started, the subsequent process is terminated, the intelligent terminal reports an error, and the user is prompted that the target sensor can fail to be started.
The intelligent terminal can use a plurality of prompting modes to report errors, such as voice prompt, light prompt, vibration prompt and text prompt. Meanwhile, the reason of the failed start of the target sensor, for example, the target sensor corresponding to the sensor label does not exist, and the ADSP subsystem 120 does not have the interface corresponding to the target sensor.
The target sensor is in a closed state before a user sends an acquisition instruction, so that energy consumption is saved, and excessive data acquisition is avoided to increase storage and cache pressure. The sensor label corresponds to the corresponding sensor uniquely, and the target sensor which the user wants to acquire the original data can be uniquely determined according to the sensor label.
When the CPU110 has successfully called back the start result of the target sensor in the function, that is, after the ADSP subsystem 120 has successfully opened the target sensor through the corresponding interface, the type of the raw data that the user wants to acquire and the number of the raw data that is transferred and displayed during acquisition are identified, corresponding data is acquired through the target sensor according to the type and the number of the raw data that the user wants to acquire, and then the acquisition result and the acquired raw data of the corresponding number are sent to the ADSP subsystem 120, and are sent to the call-back function of the CPU110 through the ADSP subsystem 120.
When the obtaining result in the callback function of the CPU110 is successful, the original data in the callback function of the CPU110 is further displayed according to a preset mode. When the acquisition result in the callback function of the CPU110 is failure, the subsequent process is terminated, and the intelligent terminal reports an error to prompt the user that the acquisition of the raw data of the target sensor fails.
The intelligent terminal can use a plurality of prompting modes to report errors, such as voice prompt, light prompt, vibration prompt and text prompt. Meanwhile, the reason for failure in acquiring the original data of the starting of the target sensor can be further displayed.
If the obtaining result in the callback function of the CPU110 is successful, that is, the original data of the target sensor is displayed on the intelligent terminal in real time, when the user does not need to obtain the data, the user inputs a close instruction through the intelligent terminal, closes the target sensor, disconnects the CPU110 from the ADSP subsystem 120, and releases the resource.
According to the invention, a user can select and generate a corresponding acquisition instruction through the intelligent terminal to acquire the original data of the target sensor, and then the required original data is displayed according to a preset display mode, so that the user can acquire the original data conveniently, and the user can know information such as the working state of the target sensor conveniently so as to debug the target sensor. On the other hand, corresponding original data can be selected and displayed in a targeted mode, and interference of irrelevant data is reduced.
And secondly, starting the target sensor according to a starting instruction in the acquisition instruction issued by the user, and returning a starting result to the intelligent terminal. If the starting fails, the user can quickly locate the fault step and the fault reason and take corresponding measures to solve the problem.
In addition, the acquisition of the original data of the target sensor is stopped based on a closing instruction input by a user, otherwise, the corresponding original data is continuously updated by the intelligent terminal in real time, the user is prevented from continuously performing the acquisition operation, and the adverse effect on equipment caused by the excessive repeated execution of the same command is avoided.
