In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.
In one embodiment of the present invention, as shown in fig. 1, a method for acquiring sensor data includes:
s100, the CPU acquires a communication interface between the CPU and the ADSP subsystem according to the acquisition instruction;
s200, the CPU and the ADSP subsystem establish communication connection through the communication interface and then start energy, the ADSP subsystem identifies the sensor label in the acquisition instruction, and a target sensor is opened;
and S300, the ADSP subsystem acquires the original data in the target sensor and sends the original data to the CPU.
Specifically, in this embodiment, a user may obtain, through an intelligent terminal, for example, a mobile phone, a tablet, etc., original data of a sensor, for example, issue a corresponding obtaining instruction through a mobile phone APP. The user opens a corresponding operation interface on the intelligent terminal, and the touch operation 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 the acquisition.
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 transmitted data is 1, the display interface of the intelligent device displays the 1 light sensation data, and new light sensation data is continuously updated 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 are X-axis, Y-axis and Z-axis coordinate information, the number of transmitted data is 3, the display interface of the intelligent device displays the 3 coordinate data in the same row, and new coordinate data are updated continuously and 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 the target sensor in the acquisition instruction, the type of the original data to be acquired and the number of the original data transmitted and displayed during acquisition can be automatically matched according to a preset configuration table. Each sensor in the configuration table corresponds to the corresponding sensor label, the type of the original data to be acquired and the number of the original data transmitted and displayed during acquisition.
For example, in the configuration table, the sensor label corresponding to the light sensor is 01, the type of the original data to be acquired is light-sensitive data, and the number of the original data to be transmitted and displayed is 1, so when the user inputs the light sensor as the target sensor on the display interface of the intelligent terminal, the corresponding sensor label, the type of the original data to be acquired and the number of the original data to be transmitted and displayed during acquisition are automatically acquired according to the configuration table.
Based on a 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, and meanwhile, the matched knowledge points which need to be memorized and mastered by the user are reduced, so that the method is convenient and quick.
In addition, the related information in the acquisition instruction can be set freely by the user, or after the corresponding information is acquired according to the preset configuration table, the user can change according to the needs of the user. For example, in the configuration table, the sensor label corresponding to the gyroscope is 02, the types of the raw data to be acquired are X-axis, Y-axis and Z-axis coordinate information, and the number of raw data to be transmitted and displayed is 3, so when the user inputs the optical sensor as the target sensor on the display interface of the intelligent terminal, the corresponding sensor label, the types of the raw data to be acquired and the number of raw data to be transmitted and displayed when acquiring 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, the corresponding types of the raw data to be acquired and the number of raw data to be transmitted and displayed when acquiring can be changed, and in addition, other configuration data such as power consumption and the like of the acquired sensor can be selected to be increased in the types of the raw data to be acquired.
The user inputs the acquisition instruction through the intelligent terminal, triggers the acquisition instruction to be sent to the CPU, acquires the 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 fetch instruction and callback function are passed to the CPU, followed by a start-up (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 labels uniquely correspond to the corresponding sensors, and the target sensor which the user wants to acquire the original data can be uniquely determined according to the sensor labels.
The corresponding relation between the sensor labels and the corresponding sensors can adopt unified labels in the industry, so that the sensor has higher universality and universal adaptability, and is more beneficial to the study and grasp of maintenance staff. Meanwhile, the privacy can be enhanced and the disclosure of private data can be avoided by setting based on the requirements of the systems of all factories.
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 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, and then sending the corresponding data to an ADSP subsystem, and sending the corresponding data to a callback function of the CPU through the ADSP subsystem. 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 through the intelligent terminal to generate a corresponding acquisition instruction 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 the information such as the working state of the target sensor conveniently, and the debugging is facilitated. On the other hand, the corresponding original data can be selected and displayed in a targeted manner, and the interference of irrelevant data is reduced.
Another embodiment of the present invention, which is an optimized embodiment of the above embodiment, as shown in fig. 2, 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, starting energy is carried out, the ADSP subsystem identifies the sensor label in the acquisition instruction, and the opening of the target sensor specifically comprises the following steps:

s230, the ADSP subsystem acquires an opening result of the target sensor and returns the opening result to a callback function of the CPU;
And S300, the ADSP subsystem acquires the original data in the target sensor and sends the original data to the CPU.
Specifically, in this embodiment, a user may obtain, through an intelligent terminal, for example, a mobile phone, a tablet, etc., original data of a sensor, for example, issue a corresponding obtaining instruction through a mobile phone APP. The user opens a corresponding operation interface on the intelligent terminal, and the touch operation 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 the acquisition.
The related information in the acquisition instruction can be freely set by a user, external data acquired by each sensor can be selected to be acquired, for example, a light sensor acquires light sensation information, a gyroscope acquires X-axis, Y-axis and Z-axis position information, and other configuration data such as power consumption and the like of the acquisition sensor can be selected to be added in the acquired type of the original data.
The user inputs the acquisition instruction through the intelligent terminal, triggers the acquisition instruction to be sent to the CPU, acquires the 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.

If the starting result is that the target sensor fails to be started, the follow-up flow is terminated, the intelligent terminal reports errors, and the user is prompted that the target sensor fails to be started.

Meanwhile, the reasons of failure in starting the target sensor, such as that the target sensor corresponding to the sensor label does not exist and the interface corresponding to the target sensor does not exist under the ADSP subsystem, can be further displayed.
The target sensor is in a closed state before a user sends an acquisition instruction, so that energy consumption is saved, and the increase of storage and cache pressure caused by the acquisition of excessive data is avoided. The sensor labels uniquely correspond to the corresponding sensors, and the target sensor which the user wants to acquire the original data can be uniquely determined according to the sensor labels.

And 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 fetch instruction and callback function are passed to the CPU, followed by a start-up (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, then the ADSP subsystem sends the starting result to a callback function of the CPU, 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 follow-up flow is terminated, the intelligent terminal reports errors, and the user is prompted that the target sensor fails to be started.
When the starting result of the target sensor in the CPU callback function is successful, that is, after the ADSP subsystem opens the target sensor through the corresponding interface, the type of the original data which the user wants to acquire 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 acquire, then the acquisition result and the acquired corresponding number of the original data are sent to the ADSP subsystem, and the callback function is sent to the CPU through the ADSP subsystem.
When the obtaining result in the callback function of the CPU is successful, the original data in the callback function of the CPU is further displayed in a preset mode. When the acquisition result in the callback function of the CPU is failure, the subsequent flow is terminated, the intelligent terminal carries out error reporting, and the user is prompted that the acquisition of the original data of the target sensor is failed.
If the acquisition 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 the user does not need to acquire, the target sensor is closed by inputting a closing instruction through the intelligent terminal, the connection between the CPU and the ADSP subsystem is disconnected, and resources are released.
According to the method and the device, the acquisition of the original data of the target sensor is stopped based on the closing instruction input by the user, otherwise, the intelligent terminal continuously updates the corresponding original data in real time, the uninterrupted acquisition operation of the user is avoided, and meanwhile, adverse effects on equipment caused by excessive repeated execution of the same command are avoided.
In one embodiment of the present invention, as shown in fig. 5, an intelligent terminal 100, which applies a high-pass platform architecture, includes a CPU110, an ADSP subsystem 120, and a plurality of sensors;
CPU110 obtains the communication interface between itself and ADSP subsystem 120 according to the obtaining instruction;
the ADSP subsystem 120, the cpu110 and the ADSP subsystem 120 establish a communication connection through the communication interface and then start energy, identify a sensor label in the acquisition instruction, and open a target sensor, where the target sensor is any one of the plurality of sensors 130;
The method specifically comprises the following steps:
ADSP subsystem 120 receives the sensor label and the start command in the acquisition command sent by CPU110;
the ADSP subsystem 120 identifies the sensor label and starts the target sensor corresponding to the sensor label according to the starting instruction;
ADSP subsystem 120 obtains the starting result of the target sensor and returns the starting result to the callback function of CPU110;

Specifically, in this embodiment, a user may obtain, through an intelligent terminal, for example, a mobile phone, a tablet, etc., original data of a sensor, for example, issue a corresponding obtaining instruction through a mobile phone APP. The user opens a corresponding operation interface on the intelligent terminal, and the touch operation 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 the acquisition.
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 transmitted data is 1, the display interface of the intelligent device displays the 1 light sensation data, and new light sensation data is continuously updated 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 are X-axis, Y-axis and Z-axis coordinate information, the number of transmitted data is 3, the display interface of the intelligent device displays the 3 coordinate data in the same row, and new coordinate data are updated continuously and 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 the target sensor in the acquisition instruction, the type of the original data to be acquired and the number of the original data transmitted and displayed during acquisition can be automatically matched according to a preset configuration table. Each sensor in the configuration table corresponds to the corresponding sensor label, the type of the original data to be acquired and the number of the original data transmitted and displayed during acquisition.
For example, in the configuration table, the sensor label corresponding to the light sensor is 01, the type of the original data to be acquired is light-sensitive data, and the number of the original data to be transmitted and displayed is 1, so when the user inputs the light sensor as the target sensor on the display interface of the intelligent terminal, the corresponding sensor label, the type of the original data to be acquired and the number of the original data to be transmitted and displayed during acquisition are automatically acquired according to the configuration table.
Based on a 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, and meanwhile, the matched knowledge points which need to be memorized and mastered by the user are reduced, so that the method is convenient and quick.
In addition, the related information in the acquisition instruction can be set freely by the user, or after the corresponding information is acquired according to the preset configuration table, the user can change according to the needs of the user. For example, in the configuration table, the sensor label corresponding to the gyroscope is 02, the types of the raw data to be acquired are X-axis, Y-axis and Z-axis coordinate information, and the number of raw data to be transmitted and displayed is 3, so when the user inputs the optical sensor as the target sensor on the display interface of the intelligent terminal, the corresponding sensor label, the types of the raw data to be acquired and the number of raw data to be transmitted and displayed when acquiring 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, the corresponding types of the raw data to be acquired and the number of raw data to be transmitted and displayed when acquiring can be changed, and in addition, other configuration data such as power consumption and the like of the acquired sensor can be selected to be increased in the types of the raw data to be acquired.
The user inputs the acquisition instruction through the intelligent terminal, triggers the acquisition instruction to be sent to the CPU110, acquires the communication interface between the CPU110 and the ADSP subsystem 120 according to the acquisition instruction, and establishes communication connection between the CPU110 and the ADSP subsystem 120.
The fetch instruction and callback function are passed to the CPU110, followed by a start-up (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 label and the start 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 120 according to the start instruction. The sensor labels uniquely correspond to the corresponding sensors, and the target sensor which the user wants to acquire the original data can be uniquely determined according to the sensor labels.
The corresponding relation between the sensor labels and the corresponding sensors can adopt unified labels in the industry, so that the sensor has higher universality and universal adaptability, and is more beneficial to the study and grasp of maintenance staff. Meanwhile, the privacy can be enhanced and the disclosure of private data can be avoided by setting based on the requirements of the systems of all factories.
The target sensor sends the starting result of the target sensor to the ADSP subsystem 120, then the ADSP subsystem 120 sends the starting result to a 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 follow-up flow is terminated, the intelligent terminal reports errors, and the user is prompted that the target sensor fails to be started.
The intelligent terminal can use various prompt modes to report errors, such as voice prompts, light prompts, vibration prompts and text prompts. Meanwhile, the reason for the failure of opening the target sensor may be further displayed, for example, the reason that the target sensor corresponding to the sensor label does not exist and the interface corresponding to the target sensor does not exist under the ADSP subsystem 120.
The target sensor is in a closed state before a user sends an acquisition instruction, so that energy consumption is saved, and the increase of storage and cache pressure caused by the acquisition of excessive data is avoided. The sensor labels uniquely correspond to the corresponding sensors, and the target sensor which the user wants to acquire the original data can be uniquely determined according to the sensor labels.
When the starting result of the target sensor in the callback function of the CPU110 is successful, that is, after the ADSP subsystem 120 opens the target sensor through the corresponding interface, the type of the original data which the user wants to acquire in the acquisition instruction and the number of the original data which is transmitted and displayed during the acquisition are identified, the corresponding data is acquired through the target sensor according to the type and the number of the original data which want to acquire, then the acquisition result and the corresponding number of the original data are sent to the ADSP subsystem 120, and the callback function is sent to 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 in a preset manner. When the acquisition result in the callback function of the CPU110 is failure, the subsequent flow is terminated, and the intelligent terminal performs error reporting to prompt the user that the acquisition of the original data of the target sensor fails.
The intelligent terminal can use various prompt modes to report errors, such as voice prompts, light prompts, vibration prompts and text prompts. Meanwhile, the reason of failure in acquiring the original data when the target sensor is started can be further displayed.
If the acquisition 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 is not in need of acquisition, the target sensor is closed by inputting a closing instruction through the intelligent terminal, the connection between the CPU110 and the ADSP subsystem 120 is disconnected, and resources are released.
According to the invention, a user can select through the intelligent terminal to generate a corresponding acquisition instruction 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 the information such as the working state of the target sensor conveniently, and the debugging is facilitated. On the other hand, the corresponding original data can be selected and displayed in a targeted manner, and the interference of irrelevant data is reduced.
And secondly, starting the target sensor according to an opening instruction in the acquisition instruction issued by the user, and returning a starting result to the intelligent terminal. If the opening fails, the user can quickly locate the fault step and the fault reason and take corresponding measures to solve the fault.
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 intelligent terminal continuously updates the corresponding original data in real time, so that the need of uninterrupted acquisition operation of the user is avoided, and meanwhile, adverse effects on equipment caused by excessive repeated execution of the same command are avoided.
