Optionally, in some application scenarios, a connection between the terminal and the master device may also be established through a wireless communication manner (e.g., wiFi), so that the master device may be remotely controlled through the terminal, and thus the slave device may be remotely managed. For example, the user can select the slave device to be managed by clicking on the display screen of the terminal, so that information such as the address of the slave device can be conveniently and directly viewed.

For example, the terminal may be a static device, such as a device fixedly disposed in a place, such as a desktop computer, although the terminal may also be a mobile device, such as a mobile phone, a wearable device, or the like.

The technical solutions in the present application will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, different technical features may be combined with each other.

Fig. 4 is a flow chart of an address management method according to an embodiment of the present application, and as shown in fig. 4, the address management method according to the embodiment may be as follows.

S101, the slave device modifies the current address of the slave device into a first address according to an address application instruction generated by the slave device triggered by a user.

For example, a master device may be communicatively coupled to a plurality of slave devices via wired or wireless connections. The plurality of slave devices do not have unique addresses when leaving the factory, so that the master device is required to allocate the unique addresses to each slave device before use, and the master device can accurately manage the slave devices when the subsequent slave devices are put into use.

Optionally, a dial switch, a button for applying for address allocation, or a touch screen for applying for address by clicking a screen may be disposed on a panel of the slave device, and the internal circuits of the slave device are respectively connected. The user can trigger the slave device to generate the application address instruction by toggling the dial switch, can trigger the slave device to generate the application address instruction by pressing a button for applying for address allocation, and can trigger the slave device to generate the application address instruction by selecting the application address after clicking the selected slave device on the touch screen.

For example, the current address refers to an address used by the slave device when triggered by the user to generate an address application instruction.

Alternatively, the current address may be a default address that is uniformly set from the factory of the device. For example, the default addresses of the plurality of slave devices are all 0x01, and the current address of the slave device triggered by the user to generate the address application instruction is also the default address, i.e. 0x01.

Alternatively, the current address may be an address assigned by the slave device prior to triggering by the user to generate the address application instruction. For example, the slave device has been assigned an address by another master device in the network composed of the other master device and the slave device, for example, 0x23, and after the slave device is added to the management network of the new master device, it is necessary to reassign the address by the new master device.

Optionally, the first address is a predetermined fixed address between the slave device and the master device, which may also be referred to as a protocol address, to indicate that the slave device whose address is the first address needs to apply for assigning a unique address to the master device, and any slave device triggered by the user to generate an address application instruction modifies the address to be the fixed address. For example, the first address may be set to 0xff, and when the user triggers the slave device to generate an application address instruction, the current address (e.g., 0x01 or 0x 23) of the slave device is modified to the first address (e.g., 0 xff).

S102, the slave device sends the first address to the master device.

Illustratively, after the slave device modifies the current address to a first address (e.g., 0 xff) according to the apply for address instruction, the slave device sends the first address (e.g., 0 xff) to the master device over a communication link with the master device.

S103, the master device receives a first address which is sent by the slave device and is modified by the slave device according to the address application instruction.

Illustratively, the master receives a first address (e.g., 0 xff) sent by the slave via a bus to which the slave is connected.

S104, the master device judges whether the first address is in a protocol address resource pool set by the master device, if the first address is in the protocol address resource pool, an address modifying instruction is generated, and a second address in an unassigned address resource pool set by the master device is obtained.

The addresses in the protocol address resource pool are set by the master device. For example, the master device sets 0xff as an address in the protocol address resource pool, and 0xff is transmitted as a first address of the slave device to the master device, and the master device determines that the first address (for example, 0 xff) is an address in the protocol address resource pool, thereby generating an address modification instruction, and acquires a second address in the unassigned address resource pool set by the master device. The address modifying instruction is used for indicating the slave device to modify the address.

For example, the addresses in the unallocated address resource pool set by the master device do not include the default address and the addresses in the protocol address resource pool. For example, when the default address is 0x01 and the address in the protocol address resource pool is 0xff, the address in the unallocated address resource pool set by the master device may be 0x02-0xfe.

For example, the master device randomly selects from the unassigned address resource pool to obtain the second address, or selects the addresses according to the sequence from low to high of the sequence numbers of the addresses in the unassigned address resource pool to obtain the second address, or selects the addresses according to the sequence from high to low of the sequence numbers of the addresses in the unassigned address resource pool to obtain the second address.

For example, when the address in the unallocated address resource pool set by the master device is 0x02-0xfe, the master device may randomly select, for example, 0x56 as the second address, may select 0x02 as the second address from low to high according to the serial number of the address, and may select 0xfe as the second address from high to low according to the serial number of the address.

S105, the master device sends an address modifying instruction and a second address to the slave device so that the slave device modifies the first address used by the slave device into the second address.

For example, the master device sends a modification address instruction and a second address to a slave device connected to the master device, wherein the current address is a first address, and the modification address instruction is used for indicating the slave device to modify the address, and the second address provides address modification information for the slave device, so that the slave device can modify the first address into the second address according to the modification address instruction.

S106, the slave device receives the address modifying instruction and the second address sent by the master device.

For example, the slave device receives, via the communication link, an address modifying instruction and a second address sent by the master device to which it is connected.

S107, the slave device modifies the first address used by the slave device into a second address according to the address modification instruction.

For example, after receiving the address modifying instruction and the second address sent by the master device connected to the slave device through the communication link, the slave device modifies the first address currently used to the second address according to the address modifying instruction.

Optionally, when the slave device modifies the address to the second address according to the address modifying instruction, the slave device and/or the master device displays a corresponding address allocation success prompt. For example, an indicator light is arranged on a panel of the slave device, the indicator light blinks when the slave device applies for modifying the address, and the indicator light is lightened for 2 seconds to give a prompt when the address of the slave device is successfully modified. For another example, when the address of the slave device is successfully modified, a corresponding dialog box may be popped up on the display screen of the master device, and the dialog box may include characters such as "successful allocation" and/or a graphic such as "v". Through various prompting modes, a user can know the address allocation progress and the address allocation result of the slave device through observation so as to timely perform the next action, and therefore the address management efficiency of the slave device is improved.

According to the embodiment of the application, the address of the slave device is modified to be the first address existing in the protocol address resource pool of the master device, and the current address can be simply and directly used for representing the first address to apply for the slave device to allocate the address to the master device. By sending the first address to the master device, the master device can determine to assign a unique address to the slave device directly from the presence of the first address in the pool of protocol address resources. The master device obtains the second address from the unassigned address resource pool, so that the second address is ensured to be the unique address, and the addresses of the plurality of slave devices are prevented from being repeated after the addresses are assigned to the plurality of slave devices. The master device can accurately send an address modifying instruction and a second address to the slave device applying for address allocation based on the first address, and the slave device modifies the first address into the second address through the address modifying instruction, so that the slave device with the address modified into the first address can modify the address into the second address again, the unique second address in the unassigned address resource pool can be accurately allocated to the slave device, and then the master device can be ensured to allocate the unique address to each slave device, so that the slave device can be effectively and accurately managed.

It should be noted that, there may be only one address in the protocol address resource pool, and multiple addresses may also be included. Correspondingly, when only one address exists in the protocol address resource pool, the user can only trigger one slave device to generate an address application instruction at a time. For example, one slave device application address is triggered by toggling the dial switch of the slave device, and another slave device application address is triggered by toggling the dial switch of another slave device after the application is completed, and the like, so that the on-site operation is convenient, the addresses and positions corresponding to different slave devices are confirmed, and the follow-up maintenance and management of the slave devices are convenient.

When a plurality of different addresses exist in the protocol address resource pool, a user can trigger a plurality of slave devices to generate an address application instruction at the same time, and in this case, the difference of triggering modes can ensure that the first addresses modified by the plurality of slave devices after generating the address application instruction are different. For example, the trigger mode 1 may be to toggle one dial switch for applying an address at the same time, the trigger mode 2 may be to toggle two dial switches for applying an address at the same time, and the trigger mode 3 may be to toggle three dial switches for applying an address at the same time, when the protocol address resource pool includes three addresses of 0xff, 0xfd and 0xfc, as shown in fig. 1, the user may modify the address to 0xff after the slave device 01 generates an application address instruction through the trigger mode 1, modify the address to 0xfd after the slave device 02 generates an application address instruction through the trigger mode 2, and modify the address to 0xfc after the slave device 03 generates an application address instruction through the trigger mode 3, thereby enabling the master device to accurately allocate different addresses to different slave devices and improving the efficiency of allocating unique addresses to the slave devices by the master device.

Optionally, after S105, an address management method provided in the embodiment of the present application may further include: the master adds the second address to the allocated address resource pool set by the master, and deletes the second address from the unallocated address resource pool of the master.

It should be appreciated that the address resource pool of the master device includes: the address in the three address resource pools are different from each other and are used for managing the addresses of the slave devices. For example, the slave device sets the address of the slave device as a default address in a unified manner at the time of shipping, and the default address does not belong to any one of the protocol address resource pool, the unassigned address resource pool, and the assigned address resource pool.

For example, among various address resource pools set by the master device, the protocol address resource pool is used for storing addresses, such as a first address, determined by the master device and the slave device, for indicating that the slave device is in a state of applying for allocation of addresses to the master device. The unassigned address resource pool is used for storing the address set by the master device and unassigned for use by the slave device. The allocated address resource pool is used for storing addresses set by the master device and allocated to the slave devices for use. It will be appreciated that the addresses in the unassigned and allocated address resource pools are different from each other and are modified in response to changes in the addresses of the slave devices to synchronize the addresses in the master and allocated address resource pools with the address state of the slave devices so that the master device can accurately manage the slave devices.

Therefore, after the second address is sent to the slave device as the address to be modified by the slave device, the master device determines that the second address is allocated to the slave device for use, so that the second address is deleted from the unassigned address resource pool and added to the assigned address resource pool, and the address allocation situation of the slave device is synchronously updated.

According to the method and the device for managing the addresses in the unallocated address resource pool and the allocated address resource pool, the address in the unallocated address resource pool and the address in the allocated address resource pool can be managed by the master device in real time according to the address change of the slave device. After the master device sends an address modification instruction and a second address in the unassigned address resource pool to the slave device, the second address assigned to the slave device is timely deleted from the unassigned address resource pool, and the second address is added into the assigned address resource pool, so that the master device can synchronously manage the address assignment situation of the slave device, and the second address is ensured not to be repeated with the second address acquired this time when the second address is acquired from the unassigned address resource pool when the address is assigned to the slave device next time, thereby ensuring the uniqueness of the address assigned to the slave device by the master device, and enabling the master device to accurately manage the slave device.

Fig. 5 is a flowchart of another address management method provided in the embodiment of the present application, and as shown in fig. 5, when at least one slave device actively applies for resetting a currently used address to a master device, the another address management method provided in the embodiment of the present application may be as follows.

S201, any first slave device generates an application reset address instruction according to user trigger, and sends the application reset address instruction and a third address currently used by the first slave device to the master device.

For example, the first slave device may be a slave device that is currently using a default address or another slave device that is currently using an address in the master device's assigned address resource pool.

In this embodiment, the third address currently used by the first slave device may be the third address currently used when the first slave device sends the address resetting instruction.

For example, the slave device applying for the reset address may be at least one slave device to which the master device assigns an address, including the slave device to which the master device assigns the second address in the above embodiments of the present application, the slave device to which the master device obtains an address from the unassigned address resource pool and assigns to the slave device, the slave device to which the address is not assigned by the master device after shipping, or the slave device to which the address is changed to the default address after modification.

It will be appreciated that the addresses currently used by the slave devices may be managed by the master device, and therefore when the user chooses to reset the addresses of some of the slave devices to the default address, the slave devices that do not need to be reset, for example, the slave devices that are addressed to the default address, cannot be avoided. The user can choose to reset the addresses of a certain number of slave devices according to his own needs, for example, 32 breakers in a warehouse, which are used and replaced, since it cannot be determined which breakers are unused, when the user needs to take 20 breakers from them for application in another scenario, in which case the user may choose 10 used breakers and 10 unused breakers and choose to reset their addresses.

For example, the slave device sends a request for resetting the address command and a third address currently used by the slave device to the master device through a communication link connected to the master device according to the request for resetting the address command.

Optionally, the third address currently used may be an address allocated by the master device to the slave device after the slave device sends an address application instruction to the master device, for example, the second address may also be a default address when leaving the factory or after modifying the address of the slave device.

The user may trigger the slave device to generate an address application reset instruction by a dial switch on the slave device, or a button for applying for a reset address, or a touch screen by clicking a screen to apply for a reset address. For example, the user may trigger the slave device to generate the application reset address instruction by toggling the dial switch, may trigger the slave device to generate the application reset address instruction by pressing a button for applying for a reset address, and may trigger the slave device to generate the application reset address instruction by clicking the selected slave device on the touch screen and then selecting the reset address. The use requirements of different occasions are met through various triggering modes.

After any one of the first slave devices generates the reset address instruction according to the user trigger, another address management method provided in the embodiment of the present application further includes: s202, the slave device modifies the third address into a default address, wherein the default address does not belong to an allocated address resource pool, an unallocated address resource pool and a protocol address resource pool which are set by the master device.

It can be understood that after the user triggers the slave device to generate the address application resetting instruction, the slave device can complete resetting by modifying the address currently used by the slave device to the default address without consent of the master device.

Optionally, after the slave device modifies the currently used third address to the default address, the slave device sends an apply for reset address instruction and the third address to the master device, or after the slave device sends the apply for reset address instruction and the third address to the master device, the slave device modifies the currently used third address to the default address. The embodiments of the present application are not limited in this regard.

S203, the master device receives an address resetting application instruction sent by the slave device and a third address currently used by the slave device.

For example, the master device receives an application reset address instruction and a third address sent by the slave device with a third address of 0x02, namely: 0x02, or receiving an application reset address instruction and a third address sent from a device whose third address is a default address (e.g., 0x 01), for example: 0x01.

S204, the master device judges whether the third address is in the allocated address resource pool of the master device, if the third address is in the allocated address resource pool of the master device, the master device deletes the third address from the allocated address resource pool according to the address resetting instruction and adds the third address into the unallocated address resource pool.

Illustratively, the allocated address resource pool includes addresses 0x02-0x12, and the unallocated address resource pool includes addresses 0x13-0xfe.

For example, after the master device receives the address resetting application instruction and 0x02 sent by the slave device with the third address of 0x02, it determines that 0x02 is in the allocated address resource pool, deletes 0x02 from the allocated address resource pool, and adds 0x02 to the unallocated address resource pool. At this time, the addresses in the allocated address resource pool include 0x03 to 0x12, and the addresses in the unallocated address resource pool include 0x02 and 0x13 to 0xfe.

For another example, after receiving the address resetting request instruction and 0x01 sent by the slave device with the third address as the default address (for example, 0x 01), the master device determines that 0x01 is not in the allocated address resource pool, that is, determines that 0x01 of the slave device does not belong to the address allocated to the slave device after the master device acquires the address from the unallocated address resource pool and joins the address in the allocated address resource pool, so that the address currently used by the slave device does not need to be reset, that is, 0x01.

For convenience of understanding, a case where the third address of the slave device is a default address will be described in detail as follows: in the case where the addresses of the slave devices all require the master device to allocate, the states and addresses of the slave devices include three types: the address is not applied for the main equipment, and the address of the slave equipment is the default address when leaving the factory; the address has been allocated by the master device, at which time the address of the slave device is recorded in the master device's allocated address resource pool; in a state where an address is allocated to the master device, but the address has not been modified to the address to which the master device has allocated, at which point the address of the slave device is an address in the protocol address resource pool. And if the address of the slave device is the address in the protocol address resource pool or the default address, the address does not need to be reset. Therefore, only when the slave device applies for resetting the address, whether the address is the address in the allocated address resource pool is judged, and whether the slave device needs to reset the address can be determined. If the address of the slave device is the address in the allocated address resource pool, the slave device can confirm that the slave device needs to reset the address of the slave device, and if the address of the slave device is not in the allocated address resource pool, the slave device is not required to reset the address of the slave device.

In the embodiment of the application, after the slave device is triggered by the user and confirms that the slave device enters the application reset address state, the third address currently used by the slave device can be directly modified into the default address, so that the reset is completed, the reply of the master device is not required to be waited, and the address resetting efficiency of the slave device and the address management efficiency of the master device are improved. After confirming that the slave device enters the application reset address state, the slave device can send the third address and the application reset address instruction to the master device, and after confirming that the third address belongs to the allocated address resource pool, the master device synchronizes the address in the allocated address resource pool and the unallocated address resource pool set by the master device according to the application reset address instruction so as to ensure that the unique address can be allocated to the slave device when the slave device applies for allocation of the address, thereby ensuring that the address allocated by the master device between the slave devices is not repeated, and further ensuring that the master device can accurately manage the slave device.

Fig. 6 is a flowchart of another address management method provided in the embodiment of the present application, as shown in fig. 6, when at least one slave device actively applies for resetting a currently used address to a master device, the another address management method provided in the embodiment of the present application may include the steps S201, S203, S204 described above, and further includes, after S204:

S205, the master device generates a confirmation reset address instruction and sends the confirmation reset address instruction to the slave device so that the slave device modifies the third address.

For example, when the master device determines that the third address is in the allocated address resource pool of the master device, it determines that the slave device corresponding to the third address needs to reset the address, and then the master device generates a command for confirming the reset address, and based on the third address, sends the command for confirming the reset address to the slave device corresponding to the third address through the communication link connected to the slave device corresponding to the third address, so that the slave device corresponding to the third address resets the third address currently used by the slave device. The slave device corresponding to the third address may be the slave device to which the second address is allocated by the master device in the above embodiment or another slave device.

S206, the slave device receives a confirmation reset address instruction sent by the master device, and modifies the third address into a default address according to the confirmation reset address instruction, wherein the default address does not belong to an allocated address resource pool, an unallocated address resource pool and a protocol address resource pool which are set by the master device.

For example, since the default address is an address uniformly set at the time of shipment of the slave device, the address of the slave device is reset by modifying the address of the slave device to the address at the time of shipment. That is, after receiving the command for confirming the reset address through the communication link connected with the master device, the slave device determines to modify the currently used third address into the default address according to the command for confirming the reset address, so that the slave device successfully resets the third address.

According to the embodiment of the application, the slave device sends the application reset address instruction and the third address to the master device, so that the master device can determine whether the third address of the slave device needs to be reset according to the third address of the slave device, when the third address exists in the allocated address resource pool, the master device can confirm that the slave device needs to reset the address according to the application reset address instruction, so that the application reset address instruction is generated, the application reset address instruction is sent to the slave device, the slave device is controlled to modify the currently used third address into the default address, after judging, the application reset is confirmed, the slave device reset address which does not need to reset the address (namely, the current address is the default address) can be avoided, and the address is synchronized in the allocated address resource pool and the unallocated address resource pool which are set by the master device, so that the slave device can be allocated to the unique address when the slave device applies for allocation of the address later, the address allocated by the master device is ensured not to be repeated, and the master device can accurately manage the slave device.

Fig. 7 is a flowchart of still another address management method according to an embodiment of the present application. As shown in fig. 7, when the master device actively resets the address currently used by at least one slave device, still another address management method provided in the embodiments of the present application may be as follows.

S301, the master device generates a reset address instruction according to user trigger, and obtains the currently used addresses of the plurality of slave devices from the allocated address resource pool of the master device.

Alternatively, the master device may be provided with a selection button for selecting the slave device and a reset button for resetting the address, and after the user selects the slave device for which the address is desired by pressing the selection button, the reset button is pressed to trigger the master device to generate the reset address instruction of the slave device for which the address is desired, and the currently used use addresses of the slave devices for which the address is desired are respectively acquired.

Optionally, the master device may be provided with a touch screen, and after clicking the slave device with the desired address on the touch screen, the user clicks the option of selecting the desired address, so as to trigger the master device to generate the command of the desired address for resetting the slave device, and obtain the currently used address of the slave device with the desired address respectively.

It will be appreciated that the master device may choose to reset the addresses of the plurality of slave devices after selecting the plurality of slave devices to enable the master device to reset the addresses of the plurality of slave devices at once.

S302, the master device deletes the use addresses of the slave devices from the allocated address resource pool of the master device, and adds the use addresses to the unallocated address resource pool of the master device.

For example, after the master device obtains the currently used addresses of the plurality of slave devices from the allocated address resource pool set by the master device, according to a reset address instruction generated by the user triggering the master device, the use addresses of the plurality of slave devices are confirmed to be reset by the slave device, and then the respective use addresses of the plurality of slave devices are deleted from the allocated address resource pool of the master device and added to the unallocated address resource pool of the master device, so that the synchronous update of the address use condition of the slave device by the master device is realized.

S303, the master device generates a confirmation reset address instruction, and sends the confirmation reset address instruction to the plurality of slave devices based on the respective use addresses of the plurality of slave devices so as to enable the plurality of slave devices to reset the respective use addresses.

For example, after generating the confirm reset address instruction, the master device sends the confirm reset address instruction to the plurality of slave devices through communication links connected to the plurality of slave devices, respectively, based on the respective use addresses of the plurality of slave devices, thereby ensuring that the plurality of slave devices can successfully receive the reset address instruction sent by the master device.

S304, the slave device receives a confirmation reset address instruction sent by the master device, and modifies the currently used address of the slave device into a default address, wherein the default address does not belong to an allocated address resource pool, an unallocated address resource pool and a protocol address resource pool which are set by the master device.

For example, each slave device of the master device selecting the reset address receives a confirmation reset address instruction sent by the master device, and then each slave device receiving the confirmation reset address instruction modifies the currently used address of the slave device to a default address uniformly set when all slave devices leave the factory, so as to achieve the purpose of resetting the used address of the slave device.

According to the method and the device, the reset address instruction is triggered by selecting the plurality of slave devices at the master device side, and the currently used use addresses corresponding to the plurality of slave devices are obtained from the allocated address resource pool of the master device according to the reset address instruction, so that the reset address instruction can be sent to each slave device according to the use addresses corresponding to the plurality of slave devices, and then the use addresses corresponding to the slave devices can be reset according to the selection made by a user at the master device.

In summary, the address management method provided in the embodiment of the present application may be used to allocate a unique address to a slave device by a master device after the slave device leaves a factory and before the slave device is put into use, so as to facilitate accurate management of multiple slave devices according to the unique addresses in use. It can also be used for the need of accurately resetting one or more slave addresses due to the damage of the slave or the replacement of the slave when the master manages the addresses of the slave. By the above embodiment, the address management functions such as the allocation and the reset of the address of the slave device can be completed with a simple operation without requiring the programming capability, while ensuring the accuracy.
