[0069] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0070] For easier understanding, please refer to Figure 1 , the embodiment of the present application provides a logistics control method applied to a host computer, including:

[0071] Step 110: The host computer configures the board information and the board communication protocol, generates a configuration table, and sends the configuration table to the board.

[0072] In the embodiment of the present application, a board controls a section of a conveyor line in a logistics line, and the board is electrically connected to a sensor (such as an inductive photoelectric) and a motor, etc. The host computer connects to the configuration page corresponding to the board to configure the board information and the board communication protocol.

[0073] Specifically, the board information configuration process includes:

[0074] Please refer to Figure 2 , select the device management page in the configuration page, and configure the device information of each board connected. The device information includes device code, device name, device type, plane number, device IP, heartbeat variable, photoelectric signal position, whether there is a barcode scanner, whether there is weighing, etc.; you can add, modify, and delete devices by clicking Add, Modify, and Delete.

[0075] Please refer to Figure 3 , select the flow management page to configure the plane number, device code, device code of the next device, plane number of the next device, board release instruction, board receiving instruction and path priority of each device. You can click Add, Modify and Delete to implement the function of adding, deleting and modifying the flow direction, and realize the configuration of the flow board path information.

[0076] Please refer to Figure 4 , Select the button function page to configure the board device information and access function bits of each type of button. The button types include emergency stop, reset, start and manual automatic. The board device information includes device IP and device code;

[0077] Please refer to Figure 5 , select the button configuration page to configure the board device information corresponding to each button. You can click Add, Modify, and Delete to implement the button function / button addition, deletion, and modification functions.

[0078] The configuration page also includes a log data page, which is used to record the log data of the message sent and received between the host computer and the board. The log data page provides the function of filtering log data according to device IP, device name, device type, and date, such as Figure 6 As shown, you can click Query and Refresh to implement the log query function.

[0079] Specifically, the configuration process of the board communication protocol includes:

[0080] like Figure 7As shown, select the function configuration page in the configuration page to configure the function code, address code, function name, function type, whether to interact, whether to record logs, whether to repeat logs and function description of the communication protocol. You can click Add, Modify and Delete to implement the add, delete and modify functions of the function configuration. Among them, the message format of the communication protocol consists of 1Byte frame information, 4Byte frame parameters and 8Byte frame data; the frame parameters include 4bits function code, 7bits slave ID and 21bits spare bits; the frame information records the effective data length of the frame data; the function code is used to distinguish messages with different functions; the slave ID is 1-31, 0 is a broadcast signal, and all slaves (ie boards) are operated; the frame data length is 8 bytes, the effective length is determined by the frame information, and zero is not used. You can refer to Figure 8 , Figure 8 The following is a message diagram showing an emergency message sent by a slave station with an ID of 1 and an error code of 0x02.

[0081] The board information and board communication protocol are configured through the above process. After the configuration is completed, a configuration table is generated. The configuration table is sent to the corresponding board through the configured communication protocol to implement the relevant configuration of the board.

[0082] Step 120 , when performing logistics control, the host computer receives the heartbeat message sent by the board and determines whether the current board is in an idle and material state by parsing the heartbeat message. If so, execute step 130 .

[0083] When performing logistics control, the board will sense whether there is material through photoelectric sensing, and upload the board status to the host computer through heartbeat message. After receiving the heartbeat message, the host computer parses it to determine whether the board on the current conveyor line (i.e., the current board) is in an idle state with material. If so, execute step 130.

[0084] Furthermore, after receiving the heartbeat message, the host computer will also parse the heartbeat message to determine whether the device connected to the current board has a weighing module or a barcode scanner. If so, it will send an inquiry message to the current board to obtain weighing information or barcode scanner data (such as the barcode scan value of the barcode scanner).

[0085] Step 130: The host computer queries all the flow path information of the current board, and selects a board with high priority that is idle and has no material as the next board.

[0086] When the current board is in an idle state with material, the host computer queries all the flow board path information of the current board, and selects a board that is idle and has no material and has a high priority as the next board (the board of the next conveyor line).

[0087] Step 140: The host computer sends a travel signal to the current board and sends a receive signal to the next board, so that the current board controls the corresponding motor to release the material and the next board controls the corresponding motor to receive the material.

[0088] The upper computer sends a trip signal to the current board and sends a receiving signal to the lower board. After receiving the release signal, the current board enters the material discharge operation state, uploads the release signal response to the upper computer, and controls the corresponding motor to rotate to release the material; after the material leaves, the board controls the motor to stop rotating, and uploads the board to the idle state without material through the heartbeat message. After receiving the receiving signal, the lower board enters the material receiving operation state, uploads the receiving signal response to the upper computer, and controls the corresponding motor to rotate to receive the material; after the material is in place, the board controls the motor to stop rotating, and uploads the board to the idle state with material through the heartbeat message.

[0089] Furthermore, after sending out the travel signal and receiving signal, the upper computer will poll several times (such as three times) to see whether it receives the response to the release signal and the receiving signal; if it receives the response to the release signal and the receiving signal, it will determine whether the current board is in the material discharging operation state and whether the next board is in the material receiving operation state. If so, it will enter the waiting start stage to determine the board status; if not, the upper computer will enter the signal sending stage and re-send the travel signal and the receiving signal.

[0090] Furthermore, after receiving the release signal or the reception signal, the board will perform a motor rotation timeout judgment to determine whether the corresponding controlled motor has been idling for more than a preset time (such as 20 seconds). If the board determines that the motor has been idling for more than the preset time, it will switch the state to a fault state, control the motor to stop rotating, and send an alarm signal to the host computer. The host computer receives the alarm signal uploaded by the board, analyzes the alarm signal to obtain the alarm information; the host computer stores the alarm information in the current alarm list, and sends a three-color light alarm signal to the board that controls the three-color light, so that the board controls the three-color light to alarm with a red light.

[0091] Furthermore, the host computer displays the alarm information to guide the user to solve the alarm problem triggered by the board card; after the fault is solved, the host computer responds to the operator's reset operation (the reset operation can be triggered by the reset button), sends the board card soft reset signal to the board card on the alarm transmission line, and sends the three-color light control signal to the board card that controls the three-color light, so that the board card on the alarm transmission line controls the motor to rotate, uploads the alarm release signal, and the board card that controls the three-color light controls the three-color light to display green; the host computer receives the alarm release signal and parses it to obtain the alarm solution information, and stores the alarm solution information in the historical alarm list. It should be noted that after controlling the motor to rotate, the board card continues to determine whether the motor has been idling for more than the preset time. If so, the alarm signal is re-reported, and if not, the subsequent process is executed.

[0092] Step 150, the host computer receives the heartbeat messages uploaded by the current board and the next board, and determines whether the current board is in an idle state with no material and whether the next board is in an idle state with material by parsing the heartbeat messages. If so, the next board is used as the current board and returns to step 130 until the last board ends the logistics control.

[0093] The upper computer receives the heartbeat messages uploaded by the current board and the next board and determines whether the current board is in an idle state with no material and whether the next board is in an idle state with material by parsing the heartbeat messages. If the current board is in an idle state with no material and the next board is in an idle state with material, the next board is used as the current board to determine whether the conveyor line where the current board is located is the last conveyor line. If not, return to step 130. If so, end the logistics control.

[0094] Furthermore, during the logistics control process, the host computer receives the target signal uploaded by the board and analyzes the variable content in the target signal; the target signal is an emergency stop signal, a reset signal, a manual signal or an automatic signal;

[0095] The host computer queries the button function module table according to the variable content function bit to obtain the function code;

[0096] The host computer queries all boards controlled by the corresponding target buttons in the button function configuration table according to the device IP, device code and function code, and sends target signals to all the queried boards, so that the queried boards control to stop rotating the motor, enter the initialization state, debugging state or running state; the target button is an emergency stop button, reset button, manual button or automatic button.

[0097] Specifically, in the logistics control process, when the emergency stop button of the current conveyor line is triggered, if the motor on the current conveyor line is running, the current board controls the motor to stop running and uploads the emergency stop signal (sent in the form of a message) to the host computer. After receiving the emergency stop signal uploaded by the current board, the host computer parses the variable content in the emergency stop signal, queries the button function module table according to the variable content function bit, and parses the function code of the emergency stop signal message; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the emergency stop button function information; the host computer queries all boards controlled by the emergency stop button in the button configuration table according to the emergency stop button function information, and sends an emergency stop signal to all the queried boards. The board that receives the emergency stop signal controls the motor to stop rotating. If the board that receives the emergency stop signal has a three-color light, the three-color light is controlled to alarm with a red light.

[0098] When the alarm on the conveyor line is lifted, all boards need to be manually reset by hardware. When the reset button on the current conveyor line is triggered, the board enters the reset state and uploads the reset signal to the host computer. After receiving the reset signal uploaded by the board, the host computer parses the variable content in the reset signal, queries the button function module table according to the variable content function bit, and parses the function code of the reset signal; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the reset button function information; the host computer queries all boards controlled by the reset button in the button configuration table according to the reset button function information, and sends a reset signal to all the queried boards. The board that receives the reset signal enters the initialization state. If the board that receives the reset signal has a three-color light, the three-color light is controlled to be green and always on.

[0099] When the board needs to enter the debugging configuration state, the manual automatic dial switch is turned to the manual direction, and the board uploads the manual signal to the host computer. The host computer parses the variable content in the manual signal, queries the button function module table according to the variable content function bit, and parses the function code of the manual signal; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the manual button function information; the host computer queries all the boards controlled by the manual button in the button configuration table according to the manual button function information, and sends manual signals to all the queried boards, and the board receiving the manual signal enters the debugging state; if the board receiving the manual signal has a three-color light, the yellow light of the three-color light is controlled to be always on, and the release and reception signals are shielded at this time.

[0100] When the board needs to enter the normal working state, the manual automatic dial switch is turned to the automatic direction, and the board uploads the automatic signal to the host computer. The host computer parses the variable content in the automatic signal, queries the button function module table according to the variable content function bit, and parses the function code of the automatic signal; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the automatic button function information; the host computer queries all the boards controlled by the automatic button in the button configuration table according to the automatic button function information, and sends the automatic signal to all the queried boards, and the board receiving the automatic signal enters the debugging state; if the board receiving the automatic signal has a three-color light, the green light of the three-color light is controlled to be always on, and the release and reception signals are sent at this time.

[0101] It should be noted that the embodiment of the present application is to read and write custom variables for reading and writing data such as the automatic state of the operator and the type of equipment, and the data type is a 2-byte unsigned short integer. The variable type may include 1 (equipment operation status), 2 (equipment operation status), 3 (alarm upload), and 4 (button function upload). The equipment operation status may include 0 (initialization), 1 (material discharge operation), 2 (material receiving operation), 3 (idle without material), 4 (idle with material)...7 (fault). In the embodiment of the present application, the status change of each board card is 4 =>1 (release command) => 3 =>2 (receive command) =>4.

[0102] The present application provides a logistics control method, which uses a board card to control a logistics line. One board card controls one section of the logistics line. After the board card is connected, the single section of the line can be debugged, and multiple types of line bodies are supported. Fixed instructions are sent according to the board card docking protocol to realize the board card to control the line operation, which reduces the complexity of the logistics line wiring, thereby reducing the difficulty of on-site implementation. The present application directly controls the motor of the logistics line through the board card, and the current state of the motor can be judged by monitoring the high and low levels of each pin on the board card, so that the output and operation of the motor equipment can be truly monitored;

[0103] Furthermore, the present application supports configurable route scheduling for multiple sections of the line body, and can determine a better route at any board node, making the route more flexible; the route can be configured according to demand, and if the line is blocked, the impact on production capacity will be small; and the host computer controls the front-end page of the board through the protocol, which is more intuitive and improves operability and maintainability.

[0104] Please refer to Fig. 9 The embodiment of the present application also provides a logistics control method applied to a board, including:

[0105] Step 210: The board receives the configuration table sent by the host computer and performs corresponding configuration according to the configuration table.

[0106] In the embodiment of the present application, a board controls a section of a conveyor line in a logistics line, and the board is connected to a sensor (such as an inductive photoelectric) and a motor and other equipment. The board performs corresponding board information configuration and board communication protocol configuration according to the configuration table sent by the host computer. Among them, the host computer connects to the configuration page corresponding to the board to perform board information configuration and board communication protocol configuration. The specific configuration process refers to the aforementioned step 110, which will not be repeated here.

[0107] Step 220: When performing logistics control, the board card determines the board card status through photoelectric sensing, and uploads the board card status to the host computer through a heartbeat message.

[0108] When performing logistics control, the board will sense whether there is material through photoelectric sensing, and upload the board status to the host computer through heartbeat messages. After receiving the heartbeat message, the host computer will parse it to determine whether the current board is in an idle state with material. If so, it will query all the flow board path information of the current board, and select a board that is idle and has no material and has a high priority as the next board.

[0109] Furthermore, when the current board is connected to a weighing module, the weighing information of the material will be obtained from the weighing module; when the current board is connected to a barcode scanner, the barcode value obtained by scanning the material will be obtained from the barcode scanner to obtain the barcode data; wherein, the barcode scanner has a built-in memory for storing the barcode data, and the barcode scanner transmits the barcode data to the board through the network port. After receiving the heartbeat message, the host computer will also parse the heartbeat message to determine whether the device connected to the current board has a weighing module or a barcode scanner. If so, it will send an inquiry message to the current board, and the current board will transmit the weighing information or barcode scanner data to the host computer through the message.

[0110] Step 230, when the board receives the release signal, it enters the material discharge operation state, uploads the release signal response to the host computer, and controls the corresponding motor to rotate to release the material; after the material leaves, the board controls the motor to stop rotating, and uploads the heartbeat message to indicate that the board is in an idle state without material.

[0111] Step 240, when the board receives the receiving signal, it enters the material receiving operation state, uploads the receiving signal response to the host computer, and controls the corresponding motor to rotate to receive the material; after the material is in place, the board controls the motor to stop rotating, and uploads the heartbeat message to indicate that the board is in an idle and material-containing state.

[0112] After selecting the next board, the upper computer sends a trip signal to the current board and a receiving signal to the next board. After receiving the release signal, the current board enters the material discharge operation state, uploads the release signal response to the upper computer, and controls the corresponding motor to rotate to release the material; after the material leaves, the board controls the motor to stop rotating, and uploads the board to the idle state with no material through the heartbeat message. After receiving the receiving signal, the next board enters the material receiving operation state, uploads the receiving signal response to the upper computer, and controls the corresponding motor to rotate to receive the material; after the material is in place, the board controls the motor to stop rotating, and uploads the board to the idle state with material through the heartbeat message.

[0113] The upper computer receives the heartbeat messages uploaded by the current board and the next board and determines whether the current board is in an idle state with no material and whether the next board is in an idle state with material by parsing the heartbeat messages. If the current board is in an idle state with no material and the next board is in an idle state with material, the next board is used as the current board to determine whether the conveyor line where the current board is located is the last conveyor line. If not, continue the logistics control. If so, end the logistics control.

[0114] Furthermore, after receiving the release signal or the reception signal, the board detects whether the motor has been idling for more than a preset time; if so, the state is switched to a fault state, the motor is controlled to stop rotating, an alarm signal is uploaded to the host computer, and when the three-color light alarm signal sent by the host computer is received, the three-color light is controlled to give a red light alarm.

[0115] Furthermore, after the fault is resolved, the board receives a board soft reset signal sent by the host computer after the fault is resolved, controls the motor operation, uploads an alarm release signal to the host computer, and receives a three-color light control signal to control the three-color light to display green.

[0116] Specifically, after parsing the alarm information, the host computer displays the alarm information to guide the user to solve the alarm problem triggered by the board card; after the fault is solved, the host computer responds to the operator's reset operation (the reset operation can be triggered by the reset button), sends the board card soft reset signal to the board card on the alarm transmission line, and sends the three-color light control signal to the board card that controls the three-color light, so that the board card on the alarm transmission line controls the motor to rotate, uploads the alarm cancellation signal to the host computer, and the board card that controls the three-color light controls the three-color light to display green; the host computer receives the alarm cancellation signal and parses to obtain the alarm solution information, and stores the alarm solution information in the historical alarm list. It should be noted that after controlling the motor to rotate, the board card continues to determine whether the motor has been idling for more than the preset time. If so, the alarm signal is re-reported, and if not, the subsequent process is executed.

[0117] Furthermore, in the logistics control process, the board uploads the target signal (the target signal is an emergency stop signal, a reset signal, a manual signal or an automatic signal) to the host computer, so that the host computer parses the variable content in the target signal, queries the button function module table according to the variable content function bit, and obtains the function code; queries all boards controlled by the corresponding target button in the button function configuration table according to the device IP, device code and function code, and sends the target signal to all queried boards; the queried board controls the stopping of the motor, entering the initialization state, the debugging state or the running state; wherein the target button is an emergency stop button, a reset button, a manual button or an automatic button.

[0118] Specifically, in the logistics control process, when the emergency stop button of the current conveyor line is triggered, if the motor on the current conveyor line is running, the current board controls the motor to stop running and uploads the emergency stop signal (sent in the form of a message) to the host computer. After receiving the emergency stop signal uploaded by the current board, the host computer parses the variable content in the emergency stop signal, queries the button function module table according to the variable content function bit, and parses the function code of the emergency stop signal message; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the emergency stop button function information; the host computer queries all boards controlled by the emergency stop button in the button configuration table according to the emergency stop button function information, and sends an emergency stop signal to all the queried boards. The board that receives the emergency stop signal controls the motor to stop rotating. If the board that receives the emergency stop signal has a three-color light, the three-color light is controlled to alarm with a red light.

[0119] When the alarm on the conveyor line is lifted, all boards need to be manually reset by hardware. When the reset button on the current conveyor line is triggered, the board enters the reset state and uploads the reset signal to the host computer. After receiving the reset signal uploaded by the board, the host computer parses the variable content in the reset signal, queries the button function module table according to the variable content function bit, and parses the function code of the reset signal; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the reset button function information; the host computer queries all boards controlled by the reset button in the button configuration table according to the reset button function information, and sends a reset signal to all the queried boards. The board that receives the reset signal enters the initialization state. If the board that receives the reset signal has a three-color light, the three-color light is controlled to be green and always on.

[0120] When the board needs to enter the debugging configuration state, the manual automatic dial switch is turned to the manual direction, and the board uploads the manual signal to the host computer. The host computer parses the variable content in the manual signal, queries the button function module table according to the variable content function bit, and parses the function code of the manual signal; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the manual button function information; the host computer queries all the boards controlled by the manual button in the button configuration table according to the manual button function information, and sends manual signals to all the queried boards, and the board receiving the manual signal enters the debugging state; if the board receiving the manual signal has a three-color light, the yellow light of the three-color light is controlled to be always on, and the release and reception signals are shielded at this time.

[0121] When the board needs to enter the normal working state, the manual automatic dial switch is turned to the automatic direction, and the board uploads the automatic signal to the host computer. The host computer parses the variable content in the automatic signal, queries the button function module table according to the variable content function bit, and parses the function code of the automatic signal; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the automatic button function information; the host computer queries all the boards controlled by the automatic button in the button configuration table according to the automatic button function information, and sends the automatic signal to all the queried boards, and the board receiving the automatic signal enters the debugging state; if the board receiving the automatic signal has a three-color light, the green light of the three-color light is controlled to be always on, and the release and reception signals are sent at this time.

[0122] The present application provides a logistics control method, which uses a board card to control a logistics line. One board card controls one section of the logistics line. After the board card is connected, the single section of the line can be debugged, and multiple types of line bodies are supported. Fixed instructions are sent according to the board card docking protocol to realize the board card to control the line operation, which reduces the complexity of the logistics line wiring, thereby reducing the difficulty of on-site implementation.

[0151] The host computer configures the board information and board communication protocol, generates a configuration table, and sends the configuration table to the board. The board performs corresponding configuration according to the received configuration table. When performing logistics control, the board determines the board status through photoelectric induction, and uploads the board status to the host computer through a heartbeat message; the host computer receives the heartbeat message sent by the board and determines whether the current board is in an idle state with material by parsing the heartbeat message. If so, it queries all the flow board path information of the current board, and selects a board that is idle and has no material and has a high priority as the next board. Furthermore, after the host computer sends out the release and reception signals, it will poll several times whether it has received the response to the release signal and the reception signal; if it has received the response to the release signal and the reception signal, it will determine whether the current board is in the discharge operation state and whether the next board is in the receiving operation state. If so, it will enter the waiting start stage to determine the board status.

[0152] The host computer sends a release signal to the current board and sends a receive signal to the lower board.

[0153] The host computer receives the heartbeat messages uploaded by the current board and the next board and determines whether the current board is in an idle state with no material and whether the next board is in an idle state with material by parsing the heartbeat messages. If so, the next board will be used as the current board to continue logistics control until the last board ends logistics control.

[0154] Furthermore, after receiving the release signal or the reception signal, the board will perform a motor rotation timeout judgment to determine whether the corresponding controlled motor has been idling for more than a preset time (such as 20 seconds). If the board determines that the motor has been idling for more than the preset time, it will switch the state to a fault state, control the motor to stop rotating, and send an alarm signal to the host computer. The host computer receives the alarm signal uploaded by the board, analyzes the alarm signal to obtain the alarm information; the host computer stores the alarm information in the current alarm list, and sends a three-color light alarm signal to the board that controls the three-color light, so that the board controls the three-color light to alarm with a red light.

[0159] Specifically, in the logistics control process, when the emergency stop button of the current conveyor line is triggered, if the motor on the current conveyor line is running, the current board controls the motor to stop running and uploads the emergency stop signal (sent in the form of a message) to the host computer. After receiving the emergency stop signal uploaded by the current board, the host computer parses the variable content in the emergency stop signal, queries the button function module table according to the variable content function bit, and parses the function code of the emergency stop signal message; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the emergency stop button function information; the host computer queries all boards controlled by the emergency stop button in the button configuration table according to the emergency stop button function information, and sends an emergency stop signal to all the queried boards. The board that receives the emergency stop signal controls the motor to stop rotating. If the board that receives the emergency stop signal has a three-color light, the three-color light is controlled to alarm with a red light.

[0160] When the alarm on the conveyor line is lifted, all boards need to be manually reset by hardware. When the reset button on the current conveyor line is triggered, the board enters the reset state and uploads the reset signal to the host computer. After receiving the reset signal uploaded by the board, the host computer parses the variable content in the reset signal, queries the button function module table according to the variable content function bit, and parses the function code of the reset signal; the host computer queries the button function configuration table according to the device IP, device code and function code to obtain the reset button function information; the host computer queries all boards controlled by the reset button in the button configuration table according to the reset button function information, and sends a reset signal to all the queried boards. The board that receives the reset signal enters the initialization state. If the board that receives the reset signal has a three-color light, the three-color light is controlled to be green and always on.

[0161] When the board needs to enter the debugging configuration state, the manual automatic dial switch is turned to the manual direction, and the board uploads the manual signal to the host computer.
