[0002] When multiple industrial devices need to communicate, a master-slave communication system can be formed. The master device in the system typically uses a polling mechanism to communicate with the slave devices. However, the master usually needs to poll all slave devices sequentially according to a fixed address list, which may result in invalid communication. Furthermore, as the number of slave devices increases, the cycle time for completing a full polling round increases linearly, leading to slow data update response and low communication efficiency.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In production and daily life, multiple devices with communication needs typically communicate using a master-slave architecture, such as heating heat pumps, swimming pool heat pumps, and smart home systems. The master device (also known as the "master") usually maintains a fixed address list and indiscriminately polls the addresses of all slave devices (also known as "slaves"). However, the number of slave devices is large, and their online status is uncertain. Devices may come online or go offline at any time due to power outages, malfunctions, etc. In the above method, the master device communicates ineffectively with offline devices, resulting in low communication efficiency. As the number of slave devices increases, the cycle for completing a full polling round increases linearly, leading to slow data update response.

[0022] Furthermore, the above method allocates the same communication resources to all devices, and high-priority devices cannot obtain lower communication latency and higher transmission frequency, making it difficult to respond to emergencies in a timely manner.

[0023] In view of the above problems, the present invention provides a multi-device communication method, apparatus and electronic device, which can be applied to multi-device communication process in master-slave architecture.

[0024] To facilitate understanding of this embodiment, a multi-device communication method disclosed in this invention will first be described in detail. The device is located on a master device; the master device is communicatively connected to multiple slave devices. The master device and slave devices can be of the same type or different types. The multiple slave devices can also be of the same type or different types. The master device may have preset device functions, such as a heat pump function, or it may only be used to communicate with slave devices and control their operating status. Specific configurations can be made according to requirements, and will not be described here.

[0025] like Figure 1 As shown, the method includes the following steps: Step S102: Identify multiple target devices that are online in slave device communication.

[0026] After the system, including master and slave devices, starts up or resets, the master device can obtain the communication addresses of each slave device and communicate with each slave device in turn. If a slave device returns a response signal to the target device, it can be determined that the slave device is online, and further, the slave device can be identified as the target device.

[0027] To reduce misjudgments caused by network fluctuations or response delays, the master device can communicate with each slave device multiple times. If, during these multiple communications, a slave device returns a response signal to the target device at least once, it can be determined that the slave device is online, and further, it can be identified as the target device.

[0028] Step S104: Based on the attribute parameters of the target device, allocate a communication time period for the target device in the communication cycle.

[0029] The aforementioned attribute parameters are used to represent the type, power, etc., of the target device, and can also be used to represent the priority of the target device. The priority of the target device can be manually set or determined based on its type, power, etc. For example, when multiple slave devices are of different types, the slave device of the first type is set to a higher priority, and the slave device of the second type is set to a lower priority; when multiple slave devices are of the same type, the slave device with greater power can be set to a higher priority. Specific settings can be configured according to requirements and are not limited here.

[0030] Different attribute parameters typically correspond to different numbers of communication time slots. For example, if the target device's priority level is 1, the corresponding number of communication time slots is 3, so three communication time slots need to be allocated to the target device in the communication cycle; if the target device's device type is Type 1, and the enemy camp's number of communication time slots is 2, then two communication time slots need to be allocated to the target device in the communication cycle.

[0031] In a communication cycle, the master device typically needs to communicate with all target devices. Therefore, the communication cycle needs to include the communication time periods corresponding to all target devices. To prevent communication between the master device and each target device from interfering with each other, the master device is usually allowed to communicate with only one target device within the same communication time period. Multiple communication time periods for the same target device within a communication cycle are usually non-contiguous; however, in practical applications, they can also be set to be continuous, and there is no restriction on this.

[0032] Time Division Multiple Access (TDMA) technology is typically used to divide the communication time corresponding to the communication channel between the master and slave devices into small communication time slots. These communication time slots are called "time slots," and each slave device communicates with the master device only within its assigned time slot. The duration of different communication time slots is usually the same, but it can also be different, depending on the requirements. There are no restrictions here.

[0033] In a communication cycle, in addition to communicating with the target device, the master device can reserve one or more communication time periods to communicate with the slave device that is offline, in order to determine whether the slave device has entered the online state.

[0034] Step S106: During the communication cycle, communicate with the target device according to the allocated communication time period.

[0035] After allocating communication time slots to target devices, the master device can be controlled to communicate with the corresponding target devices during their respective communication time slots. During communication between the master device and the target device, if the target device fails to return response data to the master device, it can be determined that the device is not online, thus confirming that the slave device is not the target device.

[0036] If, during a communication cycle, the master device communicates with an offline slave device and the slave device returns a response signal, it can be determined that the slave device is online, and thus the slave device can be identified as the target device.

[0037] Therefore, the target device may change after the communication cycle ends. Furthermore, a communication time slot for the next communication cycle can be allocated to the changed target device, thereby controlling the master device to communicate with the changed target device according to the allocated communication time slot in the next communication cycle. If the target device does not change after the communication cycle ends, the current communication time slot allocation result can still be used to control the communication between the master device and the target device.

[0038] The aforementioned multi-device communication method identifies the target device that is online in a multi-device communication process; based on the target device's attribute parameters, it allocates a communication time slot for the target device within a communication cycle; and within the communication cycle, it communicates with the target device according to the allocated communication time slot. This method allocates communication time slots based on the attribute parameters of the online target device, reducing ineffective communication between the master and slave devices, improving the efficiency of multi-device communication in a master-slave architecture, and allowing for differentiated allocation of communication time slots for devices with different attributes. It also enables timely identification of the status of critical devices and resolution of any issues arising from them, thus maintaining the safety of production and daily life.

[0039] The following embodiments provide a specific method for identifying target devices that are online in multiple slave device communications.

[0040] In practical applications, the master device can pre-configure, establish, and maintain a dynamic address pool to record the status information of each slave device. The number of devices in the address pool is related to the maximum number of devices that can be connected to the communication port. As shown in Table 1, the address pool data can include the following fields: Table 1

[0041] The master device can obtain the communication addresses of each slave device from the dynamic address pool and send status confirmation requests to the communication addresses of each slave device; for each slave device, if a response to the status confirmation request is received from the slave device, the slave device that sent the response is identified as the target device.

[0042] In practical applications, the master device can perform three rounds of fast polling (e.g., every 50ms) on all addresses in the dynamic address pool to send a status acknowledgment request to each address. If a slave device receives a response more than once, its communication status is marked as "online"; if a device does not respond to the status acknowledgment request in all three rounds, its communication status is marked as "offline". An initial communication status list can also be quickly established based on the communication status of multiple slave devices to record whether each slave device is online or offline.

[0043] The following embodiments provide a specific method for allocating communication time periods for a target device within a communication cycle based on the target device's attribute parameters.

[0044] In practical applications, the aforementioned attribute parameters can be used to indicate the priority of a target device. Different priorities typically correspond to different numbers of time slots, that is, the number of communication time slots occupied by a target device of that priority within a communication cycle. The number of target time slots corresponding to a communication cycle can be determined based on the priority of the target device. This usually requires statistically analyzing the number of time slots corresponding to the priorities of multiple target devices, then determining the statistically obtained number as the number of target time slots for that communication cycle. Furthermore, communication time slots are allocated to the target devices within the communication cycle according to the number of target time slots.

[0045] When there are multiple target devices, for each target device, the number of time periods corresponding to that target device is determined based on its priority; that is, the number of time periods corresponding to the priority of that target device is determined as the number of time periods corresponding to that target device. Further, the target number of time periods corresponding to the communication cycle can be determined based on the sum of the number of time periods corresponding to multiple target devices. For example, the sum of the number of time periods corresponding to multiple target devices can be directly determined as the target number of time periods corresponding to the current communication cycle. When a reserved time period is preset, the sum of the number of time periods corresponding to multiple target devices can be added to the preset reserved time period to obtain the target number of time periods corresponding to the communication cycle. The master device communicates with offline slave devices or newly added slave devices during the reserved time period.

[0046] When using TMD technology and a multi-slot allocation strategy to allocate different numbers of communication time slots to slave devices of different priorities, priority levels i = 1, 2, ... can be pre-set. The number of time slots per cycle for level i = S_i; the number of devices at level i = N_i; the base number of time slots = Σ(N_i × S_i), for online computing devices; the total number of time slots = base number of time slots + reserved number of time slots. The reserved number of time slots is equivalent to the reserved time period, typically one or two.

[0047] After determining the number of target time slots corresponding to the current communication cycle and the number of time slots corresponding to each target device, the following operations can be performed on each target device in descending order of priority: Based on the number of target time slots and the number of time slots corresponding to each target device, determine the time slot allocation step size for each target device. This time slot allocation step size is typically the number of time slots between two adjacent time slots of the target device within the communication cycle. For each target device, the ratio between the number of target time slots and the number of time slots corresponding to the target device can be obtained, and this ratio can be rounded down to the nearest integer; the resulting integer is the time slot allocation step size.

[0048] After determining the time period allocation step size, the communication time period corresponding to the target device needs to be determined from the multiple communication time periods contained in the communication cycle according to the time period allocation step size. When the number of time periods corresponding to the target device is greater than one, the first communication time period in the communication cycle that does not correspond to other target devices is first determined as the target communication time period corresponding to the target device. When the first and second time periods in the communication cycle both correspond to other target devices, the third time period can be determined as the first target communication time period of the current target device. Then, based on the communication time periods in the communication cycle with the time period allocation step size of the target communication time period, the next communication time period corresponding to the target device is determined. For example, when the time period allocation step size corresponding to the current target device is 2, the first target communication time period is the third time period in the communication cycle, so the sixth time period in the communication cycle can be determined as the next communication time period corresponding to the target device; if the sixth time period already corresponds to other target devices, the next communication time period corresponding to the target device can be postponed to the nearest idle time period after the sixth time period.

[0049] If the number of determined communication time periods does not reach the number of time periods corresponding to the target device, the next communication time period is determined as the target communication time period of the target device; continue to allocate communication time periods with step sizes based on the interval between the target communication time period and the communication period in the communication cycle, and determine the next communication time period corresponding to the target device, until the number of determined communication time periods corresponding to the target device is equal to the number of time periods corresponding to the target device.

[0050] In one specific embodiment, the target devices include device A, device B, and device C, and a reserved time period is set. The address pool configuration corresponding to the target devices is shown in Table 2. Table 2

[0051] The number of target time slots corresponding to the communication cycle = 1×3 + 2×2 + 1×1 + 1 = 9; the time slot allocation step size for device A is calculated as 8 / 3 = 2, so the order of communication time slots corresponding to A in the communication cycle is: 1, 4, 7; the time slot allocation step size for device B is 8 / 2 = 4, so the order of communication time slots corresponding to B1 in the communication cycle is: 2, 6, and the order of communication time slots corresponding to B2 in the communication cycle is: 3, 8; the step size for device C is 8 / 1 = 8, so the order of communication time slots corresponding to C in the communication cycle is: 5. The final communication time slot allocation results are shown in Table 3.

[0052] Table 3

[0053] Throughout the communication cycle, the host performs polling communication access to the slave devices in the order shown in Table 3 above, specifically: A, B1, B2, A, C, B1, A, B2, and a certain offline device.

[0054] After a communication cycle, based on the communication time period and the communication results with the target device, the target device currently online among multiple slave devices is determined. Typically, the slave device that sent response data can be identified as the current target device. If the current target device changes from the target device corresponding to the communication cycle, a communication time period needs to be allocated to the current target device in the next communication cycle based on its attribute parameters. The specific implementation is similar to the initial allocation of the communication time period and will not be elaborated here. In the next communication cycle, the master device communicates with the current target device according to the allocated communication time period.

[0055] Corresponding to the embodiments of the above-described multi-device communication method, this embodiment also provides a multi-device communication apparatus. This apparatus is located on a master device; the master device is communicatively connected to multiple slave devices. For example... Figure 2 As shown, the device includes: The target device determination module 202 is used to determine multiple target devices that are online in slave device communication. The time period allocation module 204 is used to allocate a communication time period to the target device in the communication cycle based on the target device's attribute parameters; The communication module 206 is used to communicate with the target device according to the allocated communication time period during the communication cycle.

[0056] The aforementioned multi-device communication device identifies target devices that are online in a multi-device communication process; based on the target device's attribute parameters, it allocates communication time slots for the target device within a communication cycle; and within the communication cycle, it communicates with the target device according to the allocated communication time slots. This method allocates communication time slots based on the attribute parameters of the online target devices, reducing ineffective communication between master and slave devices, improving the efficiency of multi-device communication in a master-slave architecture, and allowing for differentiated allocation of communication time slots for devices with different attributes. It also enables timely identification of the status of critical devices and resolution of any issues arising from them, thus maintaining the safety of production and daily life.

[0057] The aforementioned target device determination module is also used to: obtain the communication address of each slave device; send a status confirmation request to the communication address of each slave device; and for each slave device, if a response to the status confirmation request is received from the slave device, determine the slave device that sent the response as the target device.

[0058] The aforementioned attribute parameters are used to indicate the priority of the target device; the time period allocation module is also used to: determine the target time slot number corresponding to the communication cycle based on the priority of the target device; and allocate communication time periods to the target device in the communication cycle according to the target time period number.

[0059] The aforementioned target devices are multiple; the time period allocation module is also used to: for each target device, determine the number of time periods corresponding to the target device based on the priority of the target device; and determine the number of target time periods corresponding to the communication cycle based on the sum of the number of time periods corresponding to multiple target devices.

[0060] The aforementioned time period allocation module is also used to: add the sum of the number of time periods corresponding to multiple target devices to the preset number of reserved time periods to obtain the number of target time periods corresponding to the communication cycle; and for the master device to communicate with the offline slave device or the newly added slave device during the time period of the reserved time period.

[0061] The aforementioned target devices have a corresponding number of target time periods; the number of target time periods is determined based on the priority of the target devices; there are multiple target devices; the time period allocation module is also used to: perform the following operations on each target device in descending order of priority: determine the time period allocation step size of the target device based on the number of target time periods and the number of time periods corresponding to the target device; determine the communication time period corresponding to the target device from the multiple communication time periods contained in the communication cycle according to the time period allocation step size.

[0062] The aforementioned time period allocation module is also used to: when the number of time periods corresponding to the target device is greater than one, determine the first communication time period in the communication cycle that does not correspond to other target devices as the target communication time period corresponding to the target device; determine the next communication time period corresponding to the target device based on the interval between the target communication time period in the communication cycle and the time period allocation step size; determine the next communication time period as the target communication time period of the target device; continue to execute the communication time period allocation step size based on the interval between the target communication time period in the communication cycle and the time period allocation step size to determine the next communication time period corresponding to the target device, until the number of determined communication time periods corresponding to the target device is equal to the number of time periods corresponding to the target device.

[0063] The aforementioned device further includes: a target device update module, used to determine, after a communication cycle, a target device currently online among multiple slave devices based on the communication result between the target device and the communication time period; a time period update allocation module, used to allocate a communication time period for the current target device in the next communication cycle based on the attribute parameters of the current target device if the target device has changed from the target device corresponding to the communication cycle; and a second communication module, used to communicate with the current target device in the next communication cycle according to the allocated communication time period.
