[0030] Embodiment 1

[0031] Figure 1 The following is a flowchart of a method for monitoring the state of a sewing device provided in the first embodiment of the present invention. This embodiment is applicable to the situation where the sensor signals associated with the sewing device are directly obtained by using an industrial control device. This method can be executed by a state monitoring device of the sewing device. The state monitoring device of the sewing device can be implemented in the form of hardware and / or software, and the state monitoring device of the sewing device can be configured in various general computing devices. As Figure 1 shown, the method includes:

[0032] S110. Read the sewing device status file generated in the operating system kernel of the industrial control device through a daemon process; the daemon process always remains in a running state when the industrial control device is powered on;

[0033] Among them, the sewing device status file is generated by the status data acquisition driver in the operating system kernel collecting the sensor signals associated with the sewing device. The daemon process is started immediately after the operating system of the industrial control device starts running and always runs in the background until the operating system is shut down.

[0034] The operating system kernel is the core part of the operating system, which is used to manage system processes, memory, device drivers, files, and network systems, etc. The status data acquisition driver is an interrupt driver pre-written in the operating system kernel, which is used to generate a kernel file containing the sewing device status data, here called the sewing device status file. Among them, the sewing device status data includes the trigger times of each I / O pin of the sensor. In the embodiment of the present invention, the status data acquisition driver is pre-written in the operating system kernel of the industrial control device, and the trigger mode of the sensor I / O pin is pre-selected, for example, high-level trigger, low-level trigger, rising-edge trigger, or falling-edge trigger, etc. Add the input / output (Input / Outpu, abbreviated as I / O) pins of the sensors to be collected in the device tree description file in the operating system.

[0035] The status data acquisition driver can obtain the level signals sent by the sensor I / O pins according to the sensor I / O pins in the device tree description file and the pre-configured I / O pin trigger mode, and then generate a kernel file containing the sewing device status data based on the level signals, that is, the sewing device status file. During the running process, the daemon process can read the above sewing device status file from the operating system kernel according to a set time period.

[0036] In a specific example, the operating system kernel is a Linux operating system kernel based on an ARM processor, which includes a status data acquisition driver. The status data acquisition driver records the flag information and trigger times of the sensor I / O pins associated with the sewing device in the kernel file based on a preset trigger mode of the sensor I / O pins, and generates a sewing device status file. The daemon reads the sewing device status file in the Linux operating system kernel based on the ARM processor according to a set period.

[0037] The above method can use a Linux operating system based on an ARM processor to replace a dedicated single-chip microcomputer to collect sensor signals associated with the sewing device, reduce the addition of unnecessary single-chip microcomputer boards, reduce hardware costs, improve the resource utilization rate of the ARM processor, and the status data acquisition driver in the operating system kernel can collect sewing device status data quickly without an intermediate forwarding link, which can reduce data loss and improve the efficiency and reliability of signal acquisition. And by using a continuously running daemon to obtain the sewing device status file, the stability of file acquisition can be maintained, and data loss caused by sudden program shutdown can be avoided.

[0038] S120. Read the sewing device status file through the daemon to obtain the sewing device status data.

[0039] The sewing device status data is obtained by the status data acquisition driver by collecting the level signals of the sensor I / O pins associated with the sewing device. Exemplarily, the sewing device status data is the trigger times of each I / O pin of the sensor.

[0040] Optionally, the sewing device status data includes at least one of the rotation speed, working voltage, working current of the sewing device, and the production volume in the current production cycle.

[0041] In the embodiment of the present invention, after the daemon obtains the sewing device status file, it reads the content in the sewing device status file to obtain the sewing device status data. Specifically, the corresponding data of each sensor I / O pin in the sewing device status file is separated by a set delimiter, for example, a comma or a semicolon, etc. The daemon reads the content in the sewing device status file into a string, and then separates the data of each sensor I / O pin according to the preset delimiter to obtain the sewing device status data.

[0042] In addition, a dedicated sub-thread can be started in the user's QT program to obtain the sewing device status file from the Linux operating system kernel of the ARM processor every set time interval, such as 500 milliseconds. Further, the cat command is executed through the start method in the Qprocess class to read the content of the sewing device status file and store it in a set array (such as QByteArray). Further, the array is converted into a string (such as QStringList). Storing the data in the array first and then converting it into a string can avoid memory crashes caused by directly reading the data into the string.

[0043] Further, traverse the string and split the string by commas to obtain the key-value pairs associated with each sensor I / O pin. Each key-value pair is split into left and right parts by the "=" symbol. The left side of the "=" symbol is the "key", representing the identifier of the sensor I / O pin, and the right side of the "=" symbol is the "value", representing the number of trigger times of the current sensor I / O pin. Since the characters in the string are in text format, the "value" in the key-value pair needs to be converted into a numeric form. If the conversion is successful and the corresponding "key" is within the preset legal range, it is stored as sewing device status data in the corresponding position of the IN array. Finally, the sub-thread can send the read sewing device status data to the main thread, enabling the main thread to monitor the status of the sewing device based on the received sewing device status data.

[0044] S130. Write the sewing device status data into the database in the form of a queue through a daemon program, so that the main business program running in the industrial control device reads the sewing device status data from the database and monitors the status of the sewing device.

[0045] In the embodiment of the present invention, after the daemon program reads the sewing device status data, it writes the sewing device status data into the database in the form of a queue, which can avoid data loss due to power failure. Further, the main business program running in the industrial control device can read the sewing device status data from the database and monitor the status of the sewing device. Specifically, the database is pre-installed in the operating system and a database table is established. The daemon program includes the logic of reading the sewing device status file and writing the sewing device status file into the database. This involves opening a file, reading the file content, and constructing an SQL statement to insert the data into the database. Here, the API provided by the database can be used to execute the SQL statement to achieve data insertion, update, deletion, and query. Storing the sewing device status data in the database can avoid data loss and can also record the data timestamp, which is helpful for subsequent data analysis.

[0046] In the technical solution of the embodiment of the present invention, the industrial control device reads the sewing device status file generated in the operating system kernel of the industrial control device through a daemon program, reads the sewing device status file to obtain sewing device status data, and finally writes the sewing device status data into the database in the form of a queue, so that the main business program running in the industrial control device reads the sewing device status data from the database to monitor the status of the sewing device. Compared with the method of introducing a dedicated single-chip microcomputer for status monitoring, the status monitoring cost of the sewing device can be reduced, and there is no need to go through links such as forwarding of status data, simplifying the data flow, avoiding data loss, and ensuring the real-time and accuracy of status data, thereby ensuring the normal operation of the sewing device.

[0047] Embodiment 2

[0048] Figure 2 FIG. is a flowchart of a method for monitoring the status of a sewing device provided in Embodiment 2 of the present invention. This embodiment is further refined on the basis of the above embodiment and provides specific steps for reading the sewing device status file through a daemon program to obtain sewing device status data. As Figure 2 shown, the method includes:

[0049] S210. Read the sewing device status file generated in the operating system kernel of the industrial control device through a daemon program; the daemon program always remains in a running state when the industrial control device is powered on;

[0050] Among them, the sewing device status file is generated by the status data acquisition driver in the operating system kernel to acquire the sensor signals associated with the sewing device.

[0051] Optionally, the operating system kernel is a Linux operating system kernel based on an ARM processor.

[0052] Optionally, the industrial control device is configured with at least one external port, and each external port is provided with a corresponding peripheral circuit to adapt to the sensors associated with the sewing device.

[0053] In this optional embodiment, the industrial control device is configured with at least one external port, and each external port is provided with a corresponding peripheral circuit to adapt to the sensors associated with the sewing device. For example, an optocoupler isolation sensor is externally connected to the ARM processor to convert the voltage of the signal sent by the sensor I / O pin to the rated voltage of the ARM processor.

[0054] In the above optional embodiment, the operating system kernel is a Linux operating system kernel based on an ARM (Advanced RISC Machine) processor. Since it is necessary to connect the sensor to the ARM processor, if the voltage of the electrical signal transmitted from the sensor I / O pin is higher than the maximum voltage that the ARM processor can withstand, the ARM processor may be damaged. Therefore, the circuit is modified to use an optocoupler to isolate the direct contact between the sensor and the ARM processor, and convert the level transmitted from the sensor I / O pin to the rated voltage of the ARM processor.

[0055] Exemplarily, the rated voltage of the ARM processor is 3.3 volts, and the voltage of the electrical signal transmitted from the sensor I / O pin is 5 volts. At this time, the optocoupler isolation sensor can be used to convert the signal to 3.3 volts. By connecting the optocoupler isolation sensor, the range of sensors that the ARM processor can directly collect can be expanded, and the availability of the solution can be improved. Another example is that by cooperating with a 485 chip and a driver, it is possible to read external working devices such as a Programmable Logic Controller (PLC).

[0056] Optionally, the status data acquisition driver collects sensor signals based on the sensor input / output I / O pins defined in the device tree description file and the corresponding triggering method of the sensor I / O pins.

[0057] The device tree description file is a file used to store relevant devices in the Linux system. The I / O pins of the sensors to be collected can be written in the device tree description file in advance, and the new device tree description file and the new operating system kernel with the signal acquisition driver added are burned together.

[0058] In this optional embodiment, after the new operating system kernel is started based on the above, the status data acquisition driver in the kernel can collect the sewing device status data based on the sensor I / O pins written in the device description file and generate a sewing device status file.

[0059] S220. Read the sewing device status file and save the read data in an array.

[0060] In the embodiment of the present invention, after obtaining the sewing device status file, first read the sewing device status file and save the read data in an array. Exemplarily, the start method of the Qprocess class executes the cat command to read the content of the sewing device status file and saves it in a variable of the pre-set array QbyteArray.

[0061] S230. Convert the array to a string, traverse the string, and obtain the sewing device status data.

[0062] In an embodiment of the present invention, after the data in the read sewing device status file is saved in an array, the array is further converted into a string, and then by traversing the string, the sewing device status data therein is obtained. By first saving the content of the sewing device status file in an array and then converting the array into a string, compared with the method of directly writing the read sewing device status data into a string, program crashes can be avoided and memory safety can be ensured.

[0063] Optionally, traversing the string to obtain the sewing device status data includes:

[0064] Traversing the string and splitting the string based on a preset delimiter to obtain key-value pairs composed of pin identifiers and pin triggered data;

[0065] Based on a preset key-value flag character, extracting the pin triggered data in the key-value pair as the sewing device status data.

[0066] In this optional embodiment, a specific method for traversing the string to obtain the sewing device status data is provided: First, traverse the string and split the string based on a preset delimiter to obtain key-value pairs composed of pin identifiers and pin triggered data. Further, based on a preset key-value identifier, extract the pin triggered data in the key-value pair as the sewing device status data.

[0067] In a specific example, traverse the string, split the string by commas to obtain key-value pairs associated with each sensor I / O pin. Among them, each key-value pair is split into two parts on the left and right by the "=" symbol. The left side of the "=" symbol is the "key", representing the identifier of the sensor I / O pin, and the right side of the "=" symbol is the "value", representing the trigger count of the current sensor I / O pin. Since the characters in the string are all in text format, the "value" in the key-value pair needs to be converted into a numerical form. If the conversion is successful and the corresponding "key" is within the preset legal range, it is stored as the sewing device status data in the corresponding position of the IN array.

[0068] S240. Write the sewing device status data into the database in the form of a queue through a daemon program, so that the main business program running in the industrial control device reads the sewing device status data from the database to monitor the status of the sewing device.

[0069] Optionally, read the sewing device status data from the database through a subroutine and send the sewing device status data to the main business program according to a set sending period.

[0070] In the embodiments of the present invention, in addition to obtaining the sewing device status data by the daemon program, the process of obtaining the sewing device status data can also be placed in a subroutine in the user program. After the subroutine reads the sewing device status data, the sewing device status data is sent to the main business program so that the main business program can perform corresponding operations using the sewing device status data. For example, the sewing device status data is displayed on the sensor display interface, or the sewing device status data is encapsulated in Message Queuing Telemetry Transport (MQTT for short) and sent to the server through a wireless network or other means for statistical analysis of the data, or it can be saved to the local database.

[0071] By placing the operations of obtaining the sewing device status file and reading the data in the subroutine, the main business program only needs to receive and use the sewing device status data, which will not affect the task processing efficiency of the main business program and saves system overhead.

[0072] In this optional embodiment, the subroutine reads the sewing device status data from the database and sends the sewing device status data to the main business program according to the set sending period, thereby avoiding waste of main program resources caused by querying and reading the sewing device status data. In addition, the subroutine does not directly update the user interface after querying the data, but sends a signal to notify the main thread that the data has been read. After receiving the signal, the main thread will display the newly read sewing device status data. This method can make the normal interaction of the industrial control computer and the time-consuming data query run in parallel, improving the user experience and adding the function of obtaining external input at the same time.

[0073] In the technical solution of the embodiments of the present invention, by adding a status data acquisition driver to the operating system kernel of the industrial control computer, and then obtaining and reading the sewing device status file produced by the status data acquisition driver in the daemon program to obtain the sewing device status data. Compared with the method of setting up a dedicated single-chip microcomputer to collect the sewing device status data and transmitting the sewing device status data to the device through a serial port or network, there is no need to add a dedicated data acquisition single-chip microcomputer, which reduces the hardware cost and reduces the intermediate forwarding link. In addition, placing the acquisition and reading of the sewing device status file in the sub-thread will not affect the running efficiency of the main thread, can save system overhead, and improve the efficiency of sewing device status data acquisition.

[0074] Embodiment III

[0075] Figure 3 It is a flowchart of a method for monitoring the status of a sewing device provided in Embodiment III of the present invention. This embodiment is applicable to the situation of directly obtaining the sensor signals associated with the sewing device by using industrial control equipment. As Figure 3 shown, the method includes:

[0076] S310. Based on the set acquisition period, obtain the sewing device status file generated in the operating system kernel through a sub-thread;

[0077] Among them, the sewing device status file is generated by the status data acquisition driver in the operating system kernel collecting the sensor signals associated with the sewing device.

[0078] In a scenario where there is a need to read the device rotation speed, the sub-thread needs to obtain the sewing device status file according to the set acquisition period to ensure the real-time nature of the rotation speed reading. For example, based on the number of trigger times of the sensor I / O pin at the current time and the latest trigger times 500 milliseconds later, the current trigger times are recorded as old_speed, and the trigger times 500 milliseconds later are recorded as new_speed. It can be inferred that the rotation speed should be: rpm (revolutions per minute) = (new_speed - old_speed) * 2 * 60. In this way, the rotation speed of the device can be calculated.

[0079] S320. Read the sewing device status file to obtain the sewing device status data.

[0080] S330. Based on the set sending period, send the sewing device status data to the main thread.

[0081] In the embodiment of the present invention, after the sub-thread obtains the sewing device status data, the sewing device status data needs to be sent to the main thread according to the set sending period. The main thread can use the sewing device status data to process corresponding services, or can display or store the sewing device status data.

[0082] Exemplarily, the sub-thread sends the sewing device status data to the main thread once every 500 milliseconds. Using the signal-slot mechanism of Qt, when the sub-thread emits the gpioValueChanged signal, the handleGPIOValue function of the main thread will be called, and the corresponding sewing device status data will be displayed on the interface.

[0083] The technical solution of the embodiment of the present invention, by adding a status data acquisition driver in the operating system kernel, and then obtaining and reading the sewing device status file produced by the status data acquisition driver in the user program to obtain the sewing device status data. Compared with the method of setting up a dedicated single-chip microcomputer to collect the sewing device status data and transmitting the sewing device status data to the device through a serial port or network, on the one hand, there is no need to add a dedicated data acquisition single-chip microcomputer, reducing the hardware cost and reducing the intermediate forwarding link. On the other hand, using the status data acquisition driver in the operating system kernel to collect sensor signals will not affect the operation of the user program, and can effectively improve the efficiency of collecting the sewing device status data while saving system overhead.
