[0009] Please refer to Figure 1 , Figure 1 The flowchart of the conveying system control method provided by the embodiments of the present application is shown in the figure. The conveying system control method is applied to a conveying system arranged in a 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 a logistics device. The number of the device control mechanisms is equal to the number of the 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 device. The device control mechanism and the logistics device in the same section are connected. The device control mechanism is installed with control software to control the logistics device 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. The master control mechanism includes a communication module to communicate with the cloud server. The conveying system control method includes the following steps:

[0010] S10: The master control mechanism receives the host computer task issued by the cloud server, stores the received host computer task in the database, and synchronously transmits the host computer task to the remaining device control mechanisms.

[0011] Among them, the remaining device control mechanisms refer to all the remaining device control mechanisms except the master control mechanism receiving the host computer task issued by the cloud server. The remaining device control mechanisms include the remaining master control mechanisms. The communication module can be equipped with a communication device based on Ethernet, Wi-Fi, 4G or 5G mobile communication network. Preferably, before the master control mechanism receives the host computer task issued by the cloud server in the step S10, the conveying system control method further includes:

[0012] The cloud server issues an activation instruction to one of the master control mechanisms to activate the host computer task distribution function, the host computer task decomposition and arrangement function and the host computer task execution progress updating function of the master control mechanism receiving the activation instruction.

[0013] To improve the availability of the conveying system, the conveying system deploys more than one master control mechanism, that is, two or more device control mechanisms as master control mechanisms, the cloud server issues an activation instruction to one of the master control mechanisms to serve as the communication object of the cloud server, for the activated master control mechanism, and the master control mechanism can receive the upper computer task issued by the cloud server and decompose the upper computer task. The master control mechanism that does not receive the activation instruction is the inactivated master control mechanism. When the activated master control mechanism fails or a set condition occurs, the cloud server issues a shutdown activation instruction to the activated master control mechanism to close the activation state of the activated master control mechanism, and closes the upper computer task distribution function, the upper computer task decomposition and arrangement function and the upper computer task execution progress updating function of the master control mechanism. At the same time, the cloud server issues an activation instruction to one of the inactivated master control mechanisms, so that the inactivated master control mechanism becomes the activated master control mechanism, realizing the update and replacement of the activated master control mechanism. The step S10 can be specifically:

[0014] The activated master control mechanism receives the upper computer task issued by the cloud server, stores the received upper computer task in the database, and synchronously transmits the upper computer task to the device control mechanisms except the activated master control mechanism in the conveying system.

[0015] S20: The remaining device control mechanisms store the upper computer task in the database.

[0016] The database of the device control mechanism can be partitioned according to the task type, so that the task can be stored in the corresponding task partition of the database according to the task type. It can include an upper computer task area and a section task area. The step S20 can be specifically:

[0017] The remaining device control mechanisms store the upper computer task in the upper computer task area of the database.

[0018] S30: The master control mechanism decomposes the received upper computer task according to the section to obtain a plurality of section tasks, stores all section tasks in the database, synchronously transmits all section tasks to the remaining master control mechanisms, and synchronously transmits the section tasks to the device control mechanisms of the corresponding section according to the section.

[0019] S40: The device 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 state fed back by the logistics equipment.

[0021] S50: When the single section task execution is completed, the device control mechanism of the corresponding section feeds back single section task completion information to the master mechanism of the transmission section task.

[0022] S60: The master mechanism obtains the execution progress of the upper machine task according to the single section task completion information, updates the execution progress of the upper machine task in the database, and uploads the execution progress of the upper machine task to the cloud server.

The conveying system control method is applied to a conveying system in a warehouse, the warehouse is divided into a plurality of sections according to a logistics process, the conveying system comprises 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 state monitoring of the corresponding section are performed through the device control mechanism without relying on PLC for on-site coding and debugging, and the upper system does not need to be deployed on site. At least one device control mechanism serves as a master control mechanism, which can be connected with the master control mechanism through the cloud server, and the upper system does not need to be maintained on site, so that control and maintenance are more convenient. The device control mechanisms of adjacent sections are connected to enable data transmission and control between the device control mechanisms. At least one logistics equipment is provided in each section, and the device control mechanism and the logistics equipment in the same section are connected to control the logistics equipment in the same section through the device control mechanism. The conveying system control method stores the upper computer task issued by the cloud server through the master control mechanism after receiving the upper computer task, and synchronously transmits the upper computer task to the remaining device control mechanisms to realize synchronous reception of the upper computer task. The master control mechanism decomposes the received upper computer task according to the section, obtains a plurality of section tasks, synchronously transmits all section tasks to the remaining master control mechanisms, and transmits the section tasks to the device control mechanisms of the corresponding sections according to the sections, so that the master control mechanism can modify the upper computer task and write or delete the section tasks. The device control mechanism controls the corresponding logistics equipment according to the received section task, and feeds back the task state change information to the corresponding master control mechanism according to the task execution state, so as to realize monitoring of the execution progress of the upper computer task.

Moreover, the electrical box comprises a circuit board for voltage conversion, and the circuit board can process signals related to emergency stop. By providing the electrical box, it is ensured that the emergency stop signal can be correctly responded and does not depend on the device control mechanism, so that even if the device control mechanism is offline or fails, the emergency stop signal can still be output and control the logistics equipment to stop working.

[0028] Preferably, after the step S60, the conveying system control method further comprises:

[0029] When the execution progress of the host computer task is 100%, i.e. when the host computer task is completed, the section tasks corresponding to the host computer task are all completed, the main control mechanism marks the host computer task as completed, synchronously feeds back the host computer task completion state to the cloud server, and deletes the completed host computer task in the database after the host computer task completion state is successfully synchronously fed back to the cloud server, and stores the host computer task change record in the database.

[0030] The host computer task change record comprises host computer task issuing, host computer task execution progress, and host computer task completion and deletion.

[0031] Preferably, after the step S60, the conveying system control method further comprises:

[0032] The main control mechanism transmits an instruction to delete the corresponding host computer task to the remaining device control mechanisms, and the main control mechanism sends the host computer task change record to the remaining device control mechanisms, so that the remaining device control mechanisms delete the corresponding host computer task in the database and store the host computer task change record.

[0033] The host computer task change record is stored in the database in chronological order. The database of the remaining device control mechanisms is controlled by the main control mechanism with respect to the operation of the host computer task, so as to realize the synchronization of the related information of the host computer task.

[0034] Specifically, after the main control mechanism sends the host computer task change record to the remaining device control mechanisms, the conveying system control method further comprises:

[0035] When the remaining device control mechanisms have all confirmed receiving the host computer task change record, the remaining device control mechanisms feed back record change acknowledgement information to the main control mechanism, and the remaining device control mechanisms delete the host computer task change records related to the host computer task in chronological order in advance, and the main control mechanism deletes the host computer task change records related to the host computer task in chronological order in advance according to the received record change acknowledgement information.

[0037] The master control mechanism obtains local state data at the current time and stores it to a database, compares the local state data at the current time with the local state data at the previous time stored in the database, determines that the local state has changed when the local state data at the current time is different from the local state data at the previous time stored in the database, reports the device with different data and the current time data corresponding to the device to a cloud server, and synchronizes the local state data at the current time to the remaining device control mechanisms after the data reporting is completed.

[0038] The data difference refers to that the data corresponding to the current time is different from the data corresponding to the previous time, and the local state data refers to state data fed back by devices such as logistics devices and sensors installed in the warehouse, for example, the local state data can be motor working state, motor running direction, motor running speed, device temperature, proximity switch working state, vibration sensor working state, bar code reader state and current environment temperature. The motor working state refers to whether the motor is running, and the working state of the logistics device can be reflected through the motor working state. The proximity switch working state refers to whether the proximity switch is triggered. The local state data can be used to assist in work scheduling, judge the flow direction of goods, as the start and end conditions of the task, and the first end and the tail end of the logistics device are respectively provided with proximity switches, the goods can be transmitted from the first end of the logistics device to the tail end of the logistics device, and when the goods trigger the proximity switch at the tail end of the previous logistics device, the device control mechanism corresponding to the current logistics device can control the motor of the current logistics device to start; when the goods do not trigger the proximity switch at the first end of the current logistics device, the device control mechanism corresponding to the previous logistics device can control the motor of the previous logistics device to stop. The local state data can also be used for state collection, such as environment temperature and working time, so as to facilitate subsequent modeling analysis and provide device maintenance. By synchronizing the local state data at the current time to the remaining device control mechanisms, the consistency of the local state data between the device control mechanisms can be ensured, and the probability of repeated data uploading can be reduced. By comparing the state data, the device with different data and the current time data corresponding to the device are reported to the cloud server, the active uploading and updating of data are realized, and the acquisition of the state of all devices is realized. The master control mechanism continuously monitors the local state data in the database, reports the source (such as the device, which can include logistics devices and sensors) with different data corresponding to the current time data to the motion server, and after receiving the successful feedback from the motion server, the state can be modified as reported. When the uploading fails, it will try to upload again until the uploading is successful.

[0040] The master mechanism decomposes the received host computer task according to the sub-domain to obtain a plurality of sub-domain tasks;

[0041] The master mechanism stores all the sub-domain tasks in the database and synchronously transmits all the sub-domain tasks to the remaining master mechanisms;

[0042] The master mechanism synchronously transmits the sub-domain tasks to the sub-domain master mechanisms of the corresponding sub-domains according to the sub-domains;

[0043] The sub-domain master mechanism decomposes the received sub-domain task according to the section to obtain a plurality of section tasks, stores all the section tasks in the database, and synchronously transmits the section tasks to the device control mechanisms of the corresponding sections according to the sections.

[0044] The preset rule can be whether the number of sections exceeds a preset threshold or the complexity of the logistics process, and the plurality of sections of the same sub-domain are continuous and adjacent, so as to lay wires and reduce the state interaction demand between the sub-domains and the other sections of the non-sub-domains. By setting the sub-domain, the requirement for the capability of the device control mechanism, including the information processing capability and the input / output processing capability, and the wiring length can be reduced. When the sub-domain master mechanism fails, its function is realized by the activated master mechanism. In some embodiments, the sub-domain master mechanism can be in communication connection with a cloud server, so that the cloud server directly issues control instructions of the logistics equipment in the sub-domain where the sub-domain master mechanism is located to the sub-domain master mechanism.

[0045] Specifically, after the step S40, that is, after the device control mechanism of the corresponding section stores the obtained section task to the database, controls the corresponding logistics equipment to execute the obtained section task, and obtains the task execution state fed back by the logistics equipment, the conveying system control method further includes the following steps:

[0046] When a single section task is executed, the device control mechanism of the corresponding section feeds back single section task completion information to the sub-domain master mechanism of the sub-domain where the corresponding section is located;
