[0008] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0009] See also Figure 1 , Figure 1 A flow chart of a conveying system control method provided in an embodiment of the present invention, wherein the conveying system control method is applied to a conveying system located in a warehouse, wherein the warehouse is divided into a plurality of sections according to a logistics process, and the conveying system includes a cloud server, a device control mechanism, and logistics equipment. The number of the device control mechanisms is equal to the number of sections, so that each section is provided with a device control mechanism, the device control mechanisms of adjacent sections are connected, each section is provided with at least one logistics equipment, the device control mechanisms and the logistics equipment located in the same section are connected, the device control mechanism is installed with control software to control the logistics equipment in the same section through the device control mechanism, the device control mechanism is installed with a database, at least one device control mechanism serves as a master control mechanism, and the master control mechanism includes a communication module to communicate with the cloud server. The conveying system control method includes the following steps: S10: The main control mechanism receives the host computer task sent by the cloud server, stores the received host computer task in the database, and synchronously transmits the host computer task to other device control mechanisms.

[0010] Among them, the remaining device control mechanisms refer to all remaining device control mechanisms except the main control mechanism that receives the host computer task issued by the cloud server, and the remaining device control mechanisms include the remaining main control mechanisms. The communication module can be optionally equipped with a communication device based on a mobile communication network such as Ethernet, Wi-Fi, 4G or 5G. Preferably, before the main control mechanism in step S10 receives the host computer task issued by the cloud server, the conveying system control method further includes: The cloud server sends an activation instruction to one of the master control organizations to activate the host computer task distribution function, the host computer task decomposition and arrangement function, and the host computer task execution progress update function of the master control organization that receives the activation instruction.

[0011] In order to improve the availability of the conveying system, the conveying system deploys more than one master control mechanism, that is, two or more equipment control mechanisms as master control mechanisms. The cloud server sends an activation instruction to one of the master control mechanisms as the communication object of the cloud server, which is the activated master control mechanism. Then, the master control mechanism can receive the host computer tasks sent by the cloud server and perform task decomposition on the host computer tasks. The master control mechanism that has not received the activation instruction is the unactivated master control mechanism. When the activated master control mechanism fails or encounters a setting situation, the cloud server sends a shutdown activation instruction to the activated master control mechanism, turns off the activation state of the activated master control mechanism, turns off the host computer task distribution function, host computer task decomposition and arrangement function, and host computer task execution progress update function of the master control mechanism. At the same time, the cloud server sends an activation instruction to one of the unactivated master control mechanisms, so that the unactivated master control mechanism becomes the activated master control mechanism, and the update and replacement of the activated master control mechanism is realized. Then step S10 is specifically as follows: The activated master control mechanism receives the host computer tasks sent by the cloud server, stores the received host computer tasks in the database, and synchronously transmits the host computer tasks to the equipment control mechanisms other than the activated master control mechanism in the conveying system.

[0012] S20: The remaining device control mechanisms store the host computer tasks in the database.

[0013] The database of the equipment control mechanism may be partitioned according to the task type, so that the task can be stored in the task partition corresponding to the database according to the task type, which may include the host computer task area and the segment task area. Then step S20 is: The other equipment control mechanisms store the host computer tasks in the host computer task area of ​​their database.

[0014] S30: The main control mechanism decomposes the received upper computer tasks according to the sections to obtain multiple section tasks, stores all section tasks in the database, synchronously transmits all section tasks to the remaining main control mechanisms, and synchronously transmits the section tasks to the equipment control mechanisms of the corresponding sections according to the sections.

[0015] S40: The equipment control mechanism of the corresponding section stores the obtained section task in the database, controls the corresponding logistics equipment to execute the obtained section task, and obtains the task execution status fed back by the logistics equipment.

[0016] Among them, the equipment control organization performs preliminary task sorting on the obtained section tasks according to the preset task priority and business group sorting requirements, adjusts the preliminary task sorting according to the working status of the logistics equipment in the section, and after obtaining the final task sorting, controls the corresponding logistics equipment to execute the obtained section tasks according to the final task sorting.

[0017] S50: When the execution of a single section task is completed, the device control mechanism of the corresponding section feeds back the completion information of the single section task to the main control mechanism of the transmission section task.

[0018] S60: The main control mechanism obtains the execution progress of the host computer task according to the completion information of the single section task, updates and stores the execution progress of the host computer task in the database, and uploads the execution progress of the host computer task to the cloud server.

[0019] Preferably, the main control mechanism in step S60 obtains the execution progress of the host computer task according to the single section task completion information, specifically: The main control mechanism obtains the ratio of the number of completed single section tasks to the number of section tasks obtained by decomposing the upper computer tasks according to the completion information of the single section tasks as the execution progress of the upper computer tasks.

[0020] The logistics equipment can be a complex device, such as an elevator, or the logistics equipment can be a plurality of continuous conveyors. The conveying system control method is applied to the conveying system in the warehouse. The warehouse is divided into several sections according to the logistics process. The conveying system includes a cloud server, a device control mechanism and logistics equipment. The number of device control mechanisms is equal to the number of sections, so that each section is provided with a device control mechanism. The device control mechanism is installed with control software so that the control operation and status monitoring of the corresponding section are performed through the device control mechanism, without relying on PLC for on-site coding and debugging. The upper system does not need to be deployed on-site. At least one device control mechanism serves as the main control mechanism, which can communicate with the main control mechanism through the cloud server. There is no need to maintain the upper system on-site, and control and maintenance are more convenient. The device control mechanisms of adjacent sections are connected so that data can be transmitted and controlled between the device control mechanisms. Each section is provided with at least one logistics device. The device control mechanism located in the same section is connected to the logistics equipment to control the logistics equipment in the same section through the device control mechanism. The system control method receives the upper computer tasks issued by the cloud server through the main control mechanism and stores them, and synchronously transmits the upper computer tasks to the remaining equipment control mechanisms to realize the synchronous reception of the upper computer tasks, and decomposes the received upper computer tasks according to the segments through the main control mechanism to obtain multiple segment tasks and synchronously transmit all segment tasks to the remaining main control mechanisms, and transmits the segment tasks to the equipment control mechanisms of the corresponding segments according to the segments, so that the upper computer tasks can be decomposed and modified by the main control mechanism, and the segment tasks can be written and deleted. The equipment control mechanism controls the execution of the corresponding logistics equipment according to the received segment tasks, and feeds back the task status change information to the corresponding main control mechanism according to the task execution status, so as to realize the monitoring of the execution progress of the upper computer tasks. By setting the main control mechanism to communicate with the cloud server, the communication requirements with the cloud server can be reduced, the communication frequency and bandwidth requirements can be reduced, and the stability of information transmission between the cloud server and the main control mechanism can be improved.

[0021] Preferably, in some embodiments, the device control mechanism is an industrial computer with an IO board. Of course, in other embodiments, the device control mechanism is an embedded device, which can be an Orange Pi or Raspberry Pi device.

[0022] Specifically, the conveyor system also includes an electrical box, the number of which matches the number of sections and corresponds one-to-one. The equipment control mechanism is connected to the logistics equipment through the electrical box to provide power for the logistics equipment. Furthermore, the electrical box includes a circuit board for voltage conversion, which can also process emergency stop-related signals. The electrical box ensures that emergency stop signals are correctly responded to and are independent of the equipment control mechanism. Therefore, even if the equipment control mechanism is offline or malfunctions, the emergency stop signal can still be output to stop the logistics equipment.

[0023] Preferably, after step S60, the conveying system control method further includes: When the execution progress of the upper computer task is 100%, that is, when the upper computer task is completed, all the section tasks corresponding to the upper computer task are completed, the main control mechanism marks the upper computer task as completed, and synchronously feeds back the upper computer task completion status to the cloud server. After the upper computer task completion status is successfully synchronized and fed back to the cloud server, the completed upper computer task in the database is deleted, and the upper computer task change record is stored in the database.

[0024] Among them, the host computer task change record includes the host computer task issuance, host computer task execution progress, and host computer task completion and deletion.

[0025] Preferably, after deleting the host computer tasks marked as completed in the database after the host computer task completion status is successfully synchronously fed back to the cloud server, the conveying system control method further includes: The main control mechanism transmits the instruction to delete the corresponding host computer task to the other device control mechanisms, and the main control mechanism sends the host computer task change record to the other device control mechanisms, so that the other device control mechanisms delete the corresponding host computer task in the database and store the host computer task change record.

[0026] The host computer task change records are stored in the database in chronological order. The operations of the host computer tasks in the databases of other equipment control mechanisms are controlled by the main control mechanism to achieve synchronization of the relevant information of the host computer tasks.

[0027] Specifically, after the main control mechanism sends the host computer task change record to the other device control mechanisms, the conveying system control method further includes: When the remaining device control mechanisms have confirmed receipt of the upper computer task change record, the remaining device control mechanisms feedback the record change confirmation information to the main control mechanism, and the remaining device control mechanisms delete the upper computer task change record related to the upper computer task that is earlier in time sequence. The main control mechanism deletes the upper computer task change record related to the upper computer task that is earlier in time sequence based on the received record change confirmation information.

[0028] Preferably, after step S60, that is, after the main control mechanism obtains the execution progress of the host computer task according to the single section task completion information, updates and stores the execution progress of the host computer task in the database, and uploads the execution progress of the host computer task to the cloud server, the conveying system control method further includes: The main control organization obtains the local status data at the current moment and stores it in the database, compares the local status data at the current moment with the local status data at the previous moment stored in the database, and when the local status data at the current moment is different from the local status data at the previous moment stored in the database, it is judged that the local status has changed, and the device with different data and the current moment data corresponding to the device are reported to the cloud server. After the data reporting is completed, the local status data at the current moment is synchronized to the other device control organizations.

[0029] In this context, "data difference" refers to the difference between the data at the current moment and the data at the previous moment. Local status data refers to status data provided by logistics equipment and sensors installed in the warehouse. For example, local status data can include motor operating status, motor direction, motor speed, equipment temperature, proximity switch operating status, vibration sensor operating status, barcode reader status, and current ambient temperature. Motor operating status refers to whether the motor is running, reflecting the operating status of the logistics equipment. Proximity switch operating status refers to whether the proximity switch is triggered. Local status data can be used to assist in work scheduling and determine the direction of cargo flow. As a start and end condition for a task, proximity switches are installed at both ends of the logistics equipment. Cargo can be transported from the beginning to the end of the logistics equipment. When cargo triggers the proximity switch at the end of the previous logistics equipment, the device control mechanism of the current logistics equipment can control the motor of the current logistics equipment to start. When cargo does not trigger the proximity switch at the beginning of the current logistics equipment, the device control mechanism of the previous logistics equipment can control the motor of the previous logistics equipment to stop. Local status data can also be used to collect status information, such as ambient temperature and operating hours, for subsequent modeling and analysis, and to support equipment maintenance. By synchronizing the current local status data with the remaining device control mechanisms, the consistency of local status data across all device control mechanisms is ensured, reducing the likelihood of duplicate data uploads. By comparing status data, devices with different data and their corresponding current data are reported to the cloud server, enabling proactive data upload and updates, enabling access to the status of all devices. The master control mechanism continuously monitors local status data in the database, reporting the current data corresponding to different data sources (such as equipment, including logistics equipment and sensors) to the motion server. Upon receiving successful receipt feedback from the motion server, the status can be changed to "reported". If the upload fails, the master control mechanism will attempt to re-upload until the upload is successful.

[0030] Specifically, in some embodiments, the warehouse may classify sections according to preset rules to obtain sub-domains. The equipment control mechanism of one section in the sub-domain serves as the sub-domain master control mechanism, and the sub-domain master control mechanism is connected to the equipment control mechanisms of the remaining sections in the sub-domain. Before step S40, that is, the equipment control mechanism of the corresponding section stores the obtained section tasks in a database and controls the corresponding logistics equipment to execute the obtained section tasks. Before obtaining the task execution status fed back by the logistics equipment, the conveying system control method further includes: The main control mechanism decomposes the received host computer tasks according to the subdomains to obtain multiple subdomain tasks; The master control organization stores all sub-domain tasks in the database and transmits all sub-domain tasks to other master control organizations synchronously; The master control organization transfers the subdomain tasks to the subdomain master control organization of the corresponding subdomain synchronously according to the subdomain; The subdomain master control organization decomposes the received subdomain tasks according to the segments, obtains multiple segment tasks, stores all segment tasks in the database, and synchronously transmits the segment tasks to the device control organization of the corresponding segment according to the segments.

[0031] Among them, the preset rules may be whether the number of segments exceeds a preset threshold or the complexity of the logistics process, etc. Multiple segments of the same subdomain are continuous and adjacent to facilitate wiring, and reduce the need for state interaction between subdomains, and reduce the need for state interaction between subdomains and other non-subdomain segments. By setting up subdomains, the requirements for the capabilities of the equipment control mechanism and the length of wiring can be reduced. The capabilities of the equipment control mechanism include information processing capabilities and input and output processing capabilities. When the subdomain master control mechanism fails, its function is implemented by the activated master control mechanism. In some embodiments, the subdomain master control mechanism can be connected to a cloud server so that the cloud server directly issues control instructions to the subdomain master control mechanism for the logistics equipment in the subdomain where the subdomain master control mechanism is located.

[0032] Specifically, after step S40, that is, the equipment control mechanism of the corresponding section stores the obtained section task in the database, and controls the corresponding logistics equipment to execute the obtained section task. After obtaining the task execution status fed back by the logistics equipment, the conveying system control method further includes: When a single section task is completed, the device control mechanism of the corresponding section feeds back the single section task completion information to the subdomain master control mechanism of the subdomain where the corresponding section is located; The subdomain master control organization updates the status of the corresponding subdomain task, feeds back the status of the subdomain task to all master control organizations, and deletes the segment task when the status of the subdomain task is that all the segment tasks of the subdomain task are completed.

[0033] The equipment control mechanism can collect status data of the logistics equipment, switches, and sensors in its section. The equipment control mechanisms can communicate with each other through bus connections to transmit status data of the corresponding logistics equipment, switches, and sensors.

[0034] In summary, the conveying system control method of the present invention is applied to the conveying system in the warehouse. The warehouse is divided into several sections according to the logistics process. The conveying system includes a cloud server, an equipment control mechanism and logistics equipment. The number of equipment control mechanisms is equal to the number of sections, so that each section is provided with an equipment control mechanism. The equipment control mechanism is installed with control software so that the control operation and status monitoring of the corresponding section are performed through the equipment control mechanism, without relying on PLC for on-site coding and debugging, so the upper system does not need to be deployed on-site. At least one equipment control mechanism serves as the main control mechanism, so that it can communicate with the main control mechanism through the cloud server. There is no need to maintain the upper system on-site, and control and maintenance are more convenient. The equipment control mechanisms of adjacent sections are connected so that data can be transmitted and controlled between the equipment control mechanisms. Each section is provided with at least one logistics equipment. The equipment control mechanism located in the same section is connected to the logistics equipment to control the logistics equipment in the same section through the equipment control mechanism. The conveying system control method receives the upper computer task issued by the cloud server through the main control mechanism and stores it, and synchronously transmits the upper computer task to the other equipment control mechanisms to realize the synchronous reception of the upper computer task, and decomposes the received upper computer task according to the segment through the main control mechanism to obtain multiple segment tasks and synchronously transmit all segment tasks to the other main control mechanisms, and transmits the segment tasks to the equipment control mechanism of the corresponding segment according to the segment, so that the upper computer task can be decomposed and modified by the main control mechanism, and the segment task can be written and deleted. The equipment control mechanism controls the execution of the corresponding logistics equipment according to the received segment task, and feeds back the task status change information to the corresponding main control mechanism according to the task execution status, so as to realize the monitoring of the execution progress of the upper computer task. By setting the main control mechanism to communicate with the cloud server, the communication demand with the cloud server can be reduced, the communication frequency and bandwidth demand can be reduced, and the stability of information transmission between the cloud server and the main control mechanism can be improved.
