Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a communication management method for a welding machine according to an embodiment of the present invention, which is applicable to a case where a display of the welding machine communicates with a controller through a serial port, for example, the display of the welding machine sends a modification instruction of a user to the controller, so that a main control module executes a corresponding user instruction. The method can be executed by a display module of the welding machine, and specifically comprises the following steps:
and S110, sending task data to the controller.
The display serves as a communication master, and the controller of the electric welding machine serves as a communication slave. The communication master actively transmits data to the communication slave, and the communication slave receives and responds to the data. Specifically, in this embodiment, the display actively sends task data to the controller, and when the controller receives the task data, sends response data to the display. The controller, which is a core component that controls the operation of the welder, needs to process a large amount of data to enable the welder to operate properly. In the embodiment, the display is set as the communication master, and the controller is set as the communication slave, so that the processing capacity of the controller is centralized on the main items, and the processing capacity of the controller is improved.
The length of the task data in this embodiment is flexibly determined by the display, and the lengths of different task data may be different, where the data length refers to the number of bytes included in the task data.
The task data may be any one of write initialization data, read real-time class data, and write parameter class data. When the task data is write initialization data, it indicates that the display is currently in an initialization stage, and in the initialization process, the display needs to update data information of the display module before the last stop of work from the memory to issue initialization data to the controller on one hand, and needs to issue a read state information instruction to the controller on the other hand to determine the state of the controller on the other hand.
After the initialization stage is completed, the display periodically sends a real-time data reading instruction to the controller so as to determine the state information of the controller and the welder as a whole, and the display is updated and displayed on the display.
And when the display receives a new writing parameter instruction, the display issues the received process parameter or control parameter to the controller in a parameter writing data mode so as to enable the controller to execute an updated data task. For example, the display sends a parameter adjustment instruction of the user to the controller by writing parameter data, so as to instruct the controller to execute the parameter adjustment instruction.
And S120, if the data responded by the controller is waited to be received overtime or abnormal data is received, the task data is repeatedly sent until the set times is reached or normal data is received.
After the display sends a task data, a set window time is reserved for receiving the data responded by the controller, and the data responded by the controller is confirmed. When the response data of the controller is not received within the set window time, or the display receives the data responded by the controller within the window time, but the responded data is abnormal data, the display marks the task data as the task data which is not successfully responded, and repeatedly sends the task data which is not successfully responded to the controller until the data which is responded by the controller is normal data, and then the next task data is sent.
The abnormal data refers to that the verification result does not meet the agreed requirement after the display verifies the data responded by the controller. Correspondingly, the normal data refers to that the verification result meets the appointed requirement, in addition, the normal data also comprises a command for shutting down or restarting the equipment, when the display receives the shutdown or restarting command, the display clears the current communication state and enters an initialization process after restarting so as to start a new data transmission process.
In a serial communication mode, a user can select a data verification method. In this embodiment, the task determined by the display is used as a basic verification unit to verify the transmitted data, and after the display finishes transmitting one task data, the controller returns response data according to an agreed transmission protocol, which may include, as an example: command characters, data length, and a check code, wherein:
the command character is used to inform the receiving party of the purpose of the data, for example, when the command character is 0x0A, it indicates that the task data is a read data instruction; when the command character is a hexadecimal number 0x0B, it indicates that the task data is a write data instruction or the like. The display reads the command character information of the data to which the controller responds and compares the information with the command character of the transmitted task data to confirm whether the command character information of the data to which the controller responds is correct.
The data length includes the data length of the data of the response, i.e., the number of bytes included in the data of the response. On the basis of the determination of the transmitted task data and the application thereof, the data length of the response is also determined, and generally the data length of the response is the sum of the length of the task data and the data length of other data identifications. Thus, the display can confirm whether or not problems such as the lost code, the missing code, etc. occur during the data transmission by reading the data length of the responded data.
The check code is used for generating check information according to a set check protocol, and the display can determine whether transmission errors exist in data responded by the controller or not by reading the check information. For example, a CRC (cyclic redundancy check) method, a parity method, or the like can be used.
Optionally, when any one of the command character, the data length and the check code has an error, it indicates that the response data of the controller is abnormal data. On the contrary, when the command characters, the data length and the check code all meet the requirements of the protocol, the communication process of the task data is indicated to be accurate and reliable.
When the data responded by the controller is overtime or the display receives abnormal data, the display repeatedly sends the task data to confirm the current communication state, namely, the first confirmation stage is entered: the display sends the task data to the controller according to the set times.
The repeated sending times of the first confirmation stage is usually set to be 3-5 times, in the process of repeatedly sending the task data, the display confirms once after each task is sent, if the task data is confirmed to be abnormal, the task data is continuously sent again, in the verification after any repeated sending, if the response data of the controller is normal data, the repeated sending is stopped, and the transmission process of the next task data is started.
If the display cannot receive normal data in the 3-5 times of transmission process, the display enters a second confirmation stage.
And S130, if normal data are not received after the set times of repeated transmission, alarming, and repeatedly transmitting the task data to the controller according to the set frequency.
When the display does not receive normal data in the first confirmation stage, the display starts an alarm to timely feed back the abnormal communication condition to the user. Optionally, the display is provided with an alarm device, and the display sends an alarm instruction to the alarm device to instruct the alarm device to alarm, where the alarm mode may be an acoustic/optical alarm, and the alarm mode is not limited in this embodiment.
At the same time, the display starts the repeated transmission of the second confirmation phase because the display has determined that the current communication state is an abnormal state, and thus the display can reduce the transmission frequency of data to save resources of the display and the controller. The process continues until normal data is received or a user shutdown and restart instruction is received, and the process of confirming the task data which does not successfully respond is finished.
In this embodiment, the transmitted data is used as a basic check unit according to the task, after one task is transmitted, a set window time is set for receiving data responded by the controller, the data responded is checked, only after the data is checked to be qualified, the next task data is sent, and the data processing flow is strictly executed in the whole data transmission process.
The working principle of the welding machine communication management method is as follows: the display is used as a communication master to determine task data to be transmitted, after transmission of one task data is completed, data responded by the controller is verified, transmission of the next task data is carried out only after the verification is passed, otherwise, the task data which is not successfully responded is continuously transmitted, and the display realizes verification of each frame of data through strictly executing the data processing flow, so that the accuracy and the reliability of communication are improved.
According to the technical scheme of the embodiment, the display is set as a communication master, the controller is set as a communication slave, the display determines task data transmitted to the controller, a window time is set after each task is transmitted to receive data responded by the controller, the data responded by the controller is checked within the window time, and when the data responded by the controller does not meet the appointed requirement or the data responded by the controller is not received within the window time, the display continues to transmit the task data which are not successfully responded for a set number of times to the controller so as to confirm the current communication state; and if the normal response data can not be obtained within the set times, performing abnormal communication alarm, reducing the transmission frequency, and continuously sending task data which is not successfully responded to the controller until the normal data is received. In the embodiment, the accuracy and the reliability of the communication between the display and the controller of the welding machine are improved by strictly checking the transmitted task data, transmitting the next task data after the task data is correctly responded and strictly executing the data processing flow.
On the basis of the technical scheme, in the repeated sending process of the second confirmation stage, if the display receives normal response data, the display sends an alarm releasing instruction to the alarm device so as to release the abnormal alarm. For example, after checking, the worker confirms that the previous communication abnormality is caused by the falling of the communication cable, and after the communication cable is normally connected, the display can receive normal response data, and at the moment, the display releases the communication abnormality alarm, updates the current communication state to the normal communication state, and starts to transmit the next task data.
Example two
Fig. 2 is a flowchart of a welder communication management method according to a second embodiment of the present invention, where the transmission manner of task data is optimized based on the second embodiment, specifically, the method includes:
s210, generating a data queue of the task data, and determining the data at the head end of the data queue as the task data.
The data queue is a linked list formed by sequencing identifiers of data according to a certain sequence, and provides routing information for the display to transmit task data. The data queue has data execution priority, the data priority corresponding to the data identifier at the head end of the data queue is the highest, and the data priority corresponding to the data identifier at the tail end of the data queue is the lowest. Before the display sends the task data, the display configures a data identifier for each data to be transmitted and inserts the data identifier into the data queue. When data transmission is carried out, data corresponding to the data identification at the head end of the data queue is automatically determined as task data, and the data to be transmitted are transmitted according to a set sequence.
When the display receives new data to be transmitted, the display inserts a data identifier corresponding to the new data to be transmitted into the tail end of the data queue so as to update the data queue, and determines next task data to be transmitted from the updated data queue.
The display ensures the orderly data transmission by setting the data queue and determining the task data to be transmitted in sequence from the data queue.
And S220, sending task data to the controller.
And S230, if the data waiting for receiving the response of the controller is not overtime or normal data is received, deleting the task data from the data queue to update the data queue.
Wherein, the data waiting for receiving the controller response is not overtime or receives normal data, which indicates that the controller has successfully responded to the task data, at this time, the display deletes the data at the head end of the data queue to update the data queue.
When the task data is read real-time data and the read real-time data is successfully responded, the display updates the state information of the controller and the welder as a whole so as to feed back the current state of the controller to a user in time.
S240, detecting the updated data queue, and if the data queue is empty, ending the current communication; otherwise, determining the data at the head end of the data queue as the next task data.
And S250, transmitting the next task data to the controller according to the transmission process of the task data, and repeatedly executing the transmission process of the next task data until the data queue is empty.
The display transmits each task data according to an agreed transmission protocol, checks the response data of each task data according to a set data processing flow, executes in a circulating mode, updates the data queue after data transmission is successful each time until the data queue is empty, shows that no data needing to be transmitted currently exists, at the moment, communication is finished, and when new task data exist in the data queue, data transmission is started again.
According to the technical scheme of the embodiment, the display provides routing information for data transmission by establishing the data queue, and task data needing to be transmitted currently is determined from the data queue, so that the data transmission can be carried out orderly; when normal response data of the controller are received, the current data transmission process is accurate and reliable, the task data are deleted from the data queue, the data queue is updated in real time, transmission of the task data is started, and the task data are executed in a circulating mode, so that each data can be accurately transmitted in the whole communication process, and the accuracy and the reliability of data transmission are improved.

The display configures data identifiers for various types of data in the initialization data and generates a data queue of the initialization data corresponding to the data identifiers.
S330, determining task data from the data queue and sending the task data to the controller.
The step of determining the task data from the data queue means that the display determines the data corresponding to the data identifier at the head of the data queue as the task data.
And S340, if normal data are received, deleting the task data from the data queue, and updating the data queue.
S341, detecting the updated data queue, and if the data queue is empty, ending the current communication; otherwise, determining the data at the head end of the data queue as the next task data.
And S342, transmitting the next task data to the controller according to the transmission process of the task data, and repeatedly executing the transmission process of the next task data until the data queue is empty.
And S350, if the data responded by the controller is waited to be received overtime or abnormal data is received, the task data is repeatedly sent according to the set times until the set times are reached or normal data are received.
And S351, if normal data are not received after the set times of repeated transmission, alarming is carried out, and the task data are repeatedly transmitted to the controller according to the set frequency.
According to the technical scheme, when the welding machine is in an initial stage, the display reads initialization data from the storage device, a data queue related to the initialization data is generated, task data is determined from the data queue, and the initialization data is transmitted to the controller through a strict execution data processing flow so as to complete initialization of the controller.

and S410, periodically sending read state task data to the controller.
And S420, if normal data are received, deleting the read state task data from the data queue, and updating the data queue.
The step of deleting the read-state task data from the data queue means that the data identifier corresponding to the read-state task data is deleted from the data queue, so that the task data is deleted, and the data queue is updated.
