The mobile client and / or PC client receives the operation information transmitted by the server and displays it.

[0049] The production management system provided by the embodiment of the present application can monitor the operation status of the machine equipment in real time and simplify the subsequent maintenance by setting a data collection device on the machine equipment, the data collection device collects the operation information of the machine equipment, and sends the operation information to the server, the server sends the received operation information to the user terminal device, the user terminal device receives the operation information transmitted by the server and displays it. The embodiment of the present application provides a data collection device that collects and uploads sewing machine working data, that is, operation information.

[0050] The embodiment of the present application utilizes the network to perform distributed management of sewing machine data collection, which is extremely simple to operate and reduces the cost of use and maintenance. The data collection device reports the data collected from the sewing machine in real time, and through algorithm analysis, the quality, progress and efficiency of sewing can be tracked without increasing the workload of the sewing workers.

[0051] Another embodiment of the present application further supplements the system provided in the above embodiment. Optionally, the data acquisition device includes a data acquisition module, a data processing module and a wireless transmission module, wherein:

[0052] The data acquisition module is used to collect machine motion information of the machine equipment;

[0053] The data processing module is used to process the machine motion information to obtain the operation information of the machine equipment;

[0054] The wireless transmission module is used to send the operation information to the server.

[0055] On the basis of the above-mentioned embodiment, the data acquisition device mainly records the information generated by the sewing machine during the production process, that is, the operation information, stores the acquired operation information, and uploads it to the server.

[0056] The data collection device can be used to automatically collect the operating information of the current machine equipment, such as real-time start and stop information, operating time, operating speed, number of sewing stitches and number of completed pieces, and upload the collected operating information to the server in real time and summarize it on the administrator side, so that production managers can grasp the real-time work status.

[0057] Specifically, the data acquisition device includes a data acquisition module, a data processing module and a wireless transmission module, wherein:

[0058] The data acquisition module is used to acquire machine motion information of the machine equipment. Optionally, the machine motion information includes at least one of a spindle encoder signal, a stepper motor encoder signal and a thread trimming electromagnet signal of the machine equipment.

[0059] The present application embodiment takes a lockstitch sewing machine as an example, and the spindle encoder signal, step encoder signal and thread trimming electromagnet signal of the machine equipment are led out through a T-type wire clamp and connected to the data acquisition device. After the machine equipment is powered on, the data acquisition module starts working, that is, data acquisition and storage begins;

[0060] The data processing module processes the machine motion information to obtain the operation information of the machine equipment, wherein, optionally, the operation information includes at least one of the number of sewing stitches, sewing quality, operation time and work efficiency of the machine equipment, and may also include other relevant information of the machine equipment, which can be set according to actual needs.

[0061] Specifically, the working efficiency, the number of sewing needles and the running time are calculated by collecting the encoder signal of the spindle motor, and the sewing quality is calculated by collecting the encoder signal of the stepper motor; illustratively, the specific calculation method of calculating the number of sewing needles by collecting the encoder signal of the spindle motor is as follows: the encoder signal of the spindle motor is collected, and the encoder signal is usually 0-5V, which is an analog signal. For example, the encoder signal of the spindle motor collected is 4.3V, 0.1V, 3V, 0V;

[0062] The collected analog signal is processed and converted into a digital signal, that is, the above encoder signal is converted into a 1010 signal;

[0063] The obtained digital signal is counted to obtain the number of falling edges. For example, one falling edge is one stitch. By counting the number of falling edges, the number of sewing stitches completed by the equipment machine within a certain period of time can be obtained.

[0064] For example, the sewing quality is obtained through the stepper motor encoder signal, that is, whether the stroke of each needle of the sewing machine is consistent;

[0065] Collect the encoder signal of the stepper motor and obtain the angle of each step of the stepper motor;

[0066] Converting the encoder signal of the stepper motor into a digital signal;

[0067] The obtained digital signal is statistically analyzed to find out the number of falling edges. The stroke of each needle of the sewing machine is calculated by the statistical number of falling edges and the angle of each step of the stepper motor. If the stroke meets the set stroke, the sewing quality is considered to be good. If the stroke does not meet the set stroke for many times within a certain period of time, the sewing quality is considered to be poor.

[0068] During the operation of the machine, the data acquisition module continuously detects the thread trimming electromagnet signal of the machine. When it is detected that the thread trimming electromagnet signal jumps and the level remains in the state after the jump for more than a certain preset time, the data processing module processes the above collected information, considers that the current machine has performed a thread trimming action, and calculates the number of sewing pieces;

[0069] The preset time may be 100ms, or may be adjusted according to the model of the specific machine equipment.

[0070] On the basis of the above embodiment, the data collection device further includes a data storage module for storing the collected machine motion information and processed operation information of the machine equipment. The specific storage process is as follows:

[0071] Whenever the data acquisition device collects a thread trimming action, it backs up and stores the current sewing information. The storage location is located in the storage device integrated in the hardware of the data acquisition device. The stored data includes the working time of the data acquisition device, the current number of thread trimmings, and other information. After the data acquisition device is powered off and restarted, the data backed up during the last operation will first be read out from the external storage medium to avoid data loss caused by factors such as network disconnection or sudden power failure of the system.

[0072] The wireless transmission module sends the obtained transfer information to the server via the Internet and / or mobile network, wherein the wireless network may be NB-IoT.

[0073] Among them, in the above implementation process, different machine equipment information can be obtained according to actual needs, one or more of which are not specifically limited in the embodiments of the present application.

[0074] Optionally, the data acquisition device further includes a timer module, which is used to control the data acquisition module to regularly acquire machine motion information of the machine equipment, and control the wireless transmission module to regularly send the operation information to the server.

[0075] On the basis of the above embodiment, the data acquisition device also includes a timer module. In the embodiment of the present application, two timers are set, which are respectively used to control the data acquisition module to regularly collect the machine motion information of the machine equipment, and control the wireless transmission module to regularly send the operation information to the server, wherein the update time of one timer is 1s, which mainly controls the wireless transmission module to regularly send the operation information to the server, records the running time of the machine equipment, and uploads the obtained operation information of the machine equipment to the server every 1s; the update time of the other timer is 100ns, which mainly controls the data acquisition module to regularly collect the machine motion information of the machine equipment, that is, controls the data acquisition module to regularly collect the rotation speed, number of sewing needles, number of sewing pieces and other information during the operation of the machine equipment.

[0076] Among them, the time set by the timer can be set according to actual needs and is not specifically limited in the embodiments of the present application.

[0077] The specific collection steps are as follows: After the data acquisition device is powered on, the data acquisition device collects and stores the signal of the spindle being stationary. At the same time, it starts to record the power-on time of the data acquisition device in seconds. When the data acquisition device collects the falling edge of the spindle encoder signal, and the number of falling edges exceeds 3, it is considered that the machine equipment has started working. This process is to filter out false operations. When the data acquisition device believes that the machine equipment has started working, it will start to record the angle of rotation of the stepper motor, the number of falling edges of the spindle, and the interval time between two adjacent falling edges. Based on this information, the spindle speed, the number of sewing needles, the sewing quality and other information are calculated. When the speed of the machine equipment drops to 50 rpm or less, it is considered that the machine equipment has entered a stopped state. When the machine equipment is in a stopped state for more than 30s, it is considered that the current machine equipment has entered a dormant state. When the data acquisition device collects a change in the spindle signal next time, it exits the dormant state and enters the running mode.

[0078] Optionally, the wireless transmission module is at least one of a Sub-G module, a GSM module, a WiFi module or an Ethernet module.

[0079] On the basis of the above embodiments, the data acquisition device also includes a wireless transmission module for connecting to the server. One or more of them can be set on the data acquisition device to connect to the Internet through one or more of the GSM module, SUB-G module, WIFI module, Ethernet, to synchronize information and issue commands with the server. In the specific implementation process, it can be set according to actual needs and is not specifically limited in the embodiments of the present application.

[0080] Specifically, after the production management system is powered on for the first time, the data acquisition device will first automatically register with the established gateway. After successful registration, it will detect whether the current connection is successful and the signal strength and other information. If the gateway is successfully connected and the signal strength is good, it is ready to enter the data upload mode. Otherwise, it will reconnect to the gateway. If it has not been connected to the gateway for a long time, an error will be reported.

[0081] The data acquisition device successfully connects to the gateway and enters the data upload mode. In the data upload mode, first determine whether the data request instruction sent by the server has been received. If it has been received, the current system operation information will be sent to the server. If not, the normal data upload process will be entered. The normal data upload process will first detect whether the current machine equipment is in a dormant state (the machine equipment has been shut down for more than 30s). If the machine equipment is in a dormant state, it will start to receive the server's heartbeat data packet and reply. This process can inform the administrator whether the current machine is online.

[0082] If the machine device is not in sleep mode, it starts uploading data with an upload frequency of 1s (which can be adjusted according to actual needs). Each time a packet of data is uploaded, the server's feedback data packet is received and verified. If the verification fails more than 3 times, the system is restarted to resend the data.

[0083] For example, by configuring an IoT card on the machine equipment, such as adding a GSM module, the machine equipment can be directly connected to the Internet without deploying the network on site at the end user. Since the transmission of the collection of operation information in the embodiment of the present application does not require high traffic and network speed, the GSM module method has a low cost.

[0084] Optionally, the server includes an Internet server, which is connected to the machine device via a C / S mode and communicates with the user terminal device via a C / S or B / S mode.

[0085] On the basis of the above embodiment, the server includes an Internet server, which is connected to the online machine device via a C / S mode and communicates with the user terminal device via a C / S or B / S mode.

[0086] The C / S mode, that is, the client and server structure, can fully utilize the advantages of the hardware environment at both ends and reasonably distribute tasks to the client and server to achieve, thus reducing the communication overhead of the system and alleviating the pressure on the server.

[0087] The server can be connected to the user terminal device in C / S or B / S mode. The client only needs to install a browser, such as Netscape Navigator or Internet Explorer, and the server installs SQL Server, Oracle, MYSQL and other databases. The browser interacts with the database through the Web Server. The user terminal device in the embodiment of the present application includes a PC client or a mobile client. The server can communicate with the PC and the mobile phone in B / S or C / S mode. The use of the PC includes but is not limited to the browser and application mode; the use of the mobile phone includes but is not limited to the APP, WeChat applet, and WeChat public account mode.

[0088] In the embodiment of the present application, the server is connected to the user terminal device in a B / S manner, which is suitable for situations where the user base is large, the client is maintenance-free, or customer needs change frequently, and has a wider range of adaptability.

[0089] Optionally, the server further includes a notification server for sending the operation information to the user terminal device via SMS and / or WeChat.

[0090] Based on the above embodiment, the server also includes a notification server. A module that can communicate with the notification server needs to be installed on the data acquisition device. The operation information of the machine equipment can be sent to the user terminal device through the notification server in the form of SMS and / or WeChat.

[0091] It should be noted that the above-mentioned implementable methods can be implemented separately or in any combination without conflict.

[0092] The production management system provided by the embodiment of the present invention is based on the network to manage production and processing, and connects each sewing machine to the network for distributed management. Users can view the processing progress, status, and sewing processing results of the machine equipment in real time through mobile phone apps, WeChat applets, and PC web pages, thereby ensuring that problems arising from sewing activities can be handled in a timely manner.
