When cascading different groups of LEDs through a plurality of sub-controllers, each sub-controller is connected with a group of LEDs, the plurality of sub-controllers are connected in series or in parallel to a switch, and in the debugging process, the switch needs to distribute IP addresses to the plurality of sub-controllers. In a specific IP address allocation process, the switch sends an IP address allocation instruction to each sub-controller, one of the sub-controllers returns response information, at the moment, a debugger carries out IP address modification to the corresponding sub-controller beside the field device, thereby completing the IP address modification of the sub-controller, and the switch can carry out the next IP address allocation.

When the debugger modifies the IP address of the sub-controller, as described above, the sub-controller is usually installed on the top floor of a building or on the equipment positions of different floors, so that the debugger is required to hold an overhead operation certificate, but the general debugger does not have the overhead operation certificate, so that the debugger cannot modify the IP address of the sub-controller on site; in addition, in the IP address allocation mode in the prior art, debugging personnel are required to carry out IP modification beside the field device, so that the workload of debugging the early-stage device is increased, and the difficulty of later-stage maintenance is also increased.

In order to conveniently realize the cascade connection of the LED sub-controllers, the present embodiment discloses a cascade connection method of a landscape LED sub-controller, please refer to fig. 1, fig. 1 is a schematic flow diagram of a cascade connection method of a landscape LED sub-controller disclosed in the present embodiment, the cascade connection method of a landscape LED sub-controller is applied to a switch, please refer to fig. 2, fig. 2 is a cascade connection system of a landscape LED sub-controller disclosed in the present embodiment, including: a plurality of cascaded sub-controllers 2 and a switch 1, wherein the switch 1 is connected with the plurality of cascaded sub-controllers 2, specifically, can be connected in a serial manner or can be connected in a parallel manner; each sub-controller is respectively connected with each group of LEDs, and each group of LEDs is arranged on the landscape architecture. In the specific implementation process, the main control computer 3 of the landscape LED sends driving data to the corresponding sub-controller 2 through the switch 1 according to a set program, so that the sub-controller 2 drives the corresponding LED group to emit light or to extinguish, and the lamplight is realized. In the process that the switch 1 and the plurality of cascaded sub-controllers 2 are in interactive communication, each sub-controller 2 shares the total bandwidth of the switch 1, in general, the switch 1 is connected with N sub-controllers 2, and each sub-controller 2 allocates the total bandwidth according to N shares, namely, assuming that the total bandwidth of the switch 1 is M, the bandwidth obtained by each sub-controller 2 is M/N, and the sub-controller 2 occupies the bandwidth of M/N no matter whether the sub-controller 2 is in a working state or not.

Referring to fig. 1, the cascading method of the landscape LED sub-controllers includes: step S100, step S200, and step S300, wherein:

Step S100, a designated IP address allocation instruction is sent to a plurality of sub controllers. Specifically, the multiple sub-controllers 2 form a topology array, and control different groups of LED groups respectively, where the physical areas of the LED groups are different. In a specific embodiment, referring to fig. 2, a plurality of sub-controllers 2 are divided into a plurality of groups, each group of sub-controllers 2 is sequentially arranged to form a plurality of rows, and the sub-controllers 2 of different groups are arranged in columns, so that the plurality of sub-controllers 2 form a topological array of a matrix. The facade of the landscape architecture is provided with numerous LEDs which are controlled by different sub-controllers 2 according to the location area in which they are located, i.e. each sub-controller 2 has a respective controlled area. Through cooperation among different sub controllers 2, LEDs arranged on the outer facade of the landscape building emit light or are extinguished according to a preset program, so that a lamplight show is realized. In this embodiment, the specified IP address allocation instruction may be an allocation instruction or an instruction with IP address information.

Step S200, receiving response information returned by the target sub-controller, wherein the target sub-controller is a sub-controller which returns response information among the plurality of sub-controllers. In this embodiment, the response information includes the MAC address of the target sub-controller, and during this period, the target sub-controller sends a prompt message to the debugger to prompt the physical area where the LED group controlled by the target sub-controller is located. In a specific embodiment, when receiving the response information returned by the target slave controller, the switch can learn the current interaction object, and based on the current interaction object, the switch can allocate an IP address to the target slave controller. In this embodiment, the prompt message may be a sound emitted by the target sub-controller, or may be that the target sub-controller prompts the debugger of the position of the target sub-controller by flashing its LED. However, there is a problem that the switch cannot know the coordinates of the target slave controllers in the topology array, that is, the switch cannot know the physical area corresponding to the target slave controllers, and in the prior art, a debugger needs to go to the slave controller topology array to confirm the target slave controllers. Therefore, the target sub-controller sends the prompt information to the debugger, so that the debugger can be prompted to the position of the target sub-controller, and the debugger can bind the IP address of the target sub-controller according to the position of the target sub-controller conveniently.

And step S300, IP address binding information is sent to the target sub-controller so as to bind the MAC address, the IP address and the sub-controller array serial number of the target sub-controller. In this embodiment, the number of the sub-controller array characterizes the physical area where the LED group controlled by the target sub-controller is located, so that the MAC address of the target sub-controller, the number of the sub-controller array, and the physical area where the LED group is located are in one-to-one correspondence. Specifically, after determining the physical area where the LED group controlled by the target slave device corresponds to (i.e., the array coordinate where the target slave device is located), the array serial number may be allocated to the target slave device, so as to bind the MAC address, the IP address, and the slave device array serial number of the target slave device. In one embodiment, when the specified IP address allocation instruction is an instruction with IP address information, the sequence number of the slave array of the target slave can be directly updated, so as to bind the MAC address, the IP address and the sequence number of the slave array of the target slave; in another embodiment, when the specified IP address allocation instruction is an allocation instruction, an IP address corresponding to the sequence number of the sub-controller array may be provided to the target sub-controller, so that the sub-controller array sequence number and the IP address sequence number may be easily associated, for example, the last bit of the IP address is arranged in order, which is consistent with the sub-controller array sequence number, so as to facilitate memory and management. In this embodiment, by binding the MAC address, the IP address, and the serial number of the sub-controller array of the target sub-controller, in the process of implementing the landscape architecture "light show" by using the computer 3, the serial number of the array can be directly used for programming, so that the programmer can program and control the light conveniently, and the position of the array where the sub-controller is located can be intuitively distinguished.

In a specific embodiment, in step S200, the prompt message sent by the target sub-controller to the debugger may be sound and/or light sent by the target sub-controller, or the target sub-controller may drive the LED group in the corresponding physical area to emit light. In a preferred embodiment, the prompt information includes that the target sub-controller drives the corresponding physical area LED group to emit light, the purpose of knowing the position of the target sub-controller is to determine the physical area of the LED group corresponding to the target sub-controller, and the sub-controllers and the LED group are connected in advance, so that the sub-controllers and the LED group have completed one-to-one correspondence, in this case, the target sub-controller drives the corresponding physical area LED group to emit light to prompt a debugger, so that the debugger can directly position the physical area of the LED group through the emitted LED group; and because the LEDs are arranged on the outer elevation of the building, debugging personnel do not need to go to the installation site (a top building, an outer elevation of a floor and the like) of the sub-controllers, but can directly observe the lighting condition of the building at a distance, the LED group corresponding to the current target sub-controllers and the physical area where the LED group is positioned can be known, namely, the debugging personnel can finish cascading of the sub-controllers by sitting in an office or an outdoor fixed position, and only the debugging personnel have enough distance with the building and can observe the lighting condition of the LED group of the building.

In an alternative embodiment, in step S300, sending the IP address binding information to the target microcontroller includes: generating a target IP address according to a serial number corresponding to the position of the target sub-controller, wherein the target IP address is one of a plurality of IP addresses which are arranged in sequence; and sending the target IP address to the target sub-controller as IP address binding information so that the target sub-controller binds the target IP address. Specifically, the switch presets a plurality of IP addresses and is arranged in sequence, the arrangement sequence of the switch corresponds to the sequence number of the sub-controllers, after receiving the prompt information of the target sub-controllers, a debugger can determine the position of the target sub-controllers and the corresponding sequence number of the sub-controllers, at the moment, the debugger can determine the IP address corresponding to the target sub-controllers according to the sequence number of the sub-controllers, and send the corresponding IP address as a target IP address to the target sub-controllers, so that the target IP address corresponds to the MAC address of the target sub-controllers, and the binding of the target IP address and the MAC address of the target sub-controllers is completed, and the binding of the MAC address, the IP address and the array sequence number of the sub-controllers of the target sub-controllers is realized.

In order to improve cascading efficiency of LED sub-controllers and reduce human errors caused by manual binding, in an alternative embodiment, a plurality of sub-controllers are divided into a plurality of groups, each group of sub-controllers is sequentially arranged, specifically, please refer to a dashed line frame in fig. 2, each dashed line frame is a group of sub-controllers, the sub-controllers in the group are sequentially arranged, for example, 01, 02, 03, 04 … …, and the arrangement sequence of a plurality of IP addresses preset by the switch corresponds to the sequence of sequence numbers of the sub-controllers, so that the IP addresses are sequentially associated with the sequence numbers of the sub-controllers. After step S300, further includes:

Step S410, the IP addresses of other sub-controllers in the same group as the target sub-controller are determined in sequence according to the target IP address and the corresponding serial number. Specifically, referring to the dashed box in fig. 2, after receiving the response information returned by the target slave controller in step S200, the slave controller group in which the target slave controller is located and the serial number (e.g. number 01) thereof can be determined, and at this time, for other slave controllers in the slave controller group, the IP address and the slave controller serial number associated with each slave controller can be determined according to the sequence.

In step S420, other sub-controllers in the same group sequentially determine respective IP address binding information with reference to the head station. Specifically, the target slave controllers can synchronize the IP addresses of other slave controllers to each slave controller in the group in a self-adding or self-subtracting mode, so that each slave controller in the group can respectively and automatically bind respective MAC addresses, IP addresses and slave controller array serial numbers in sequence, and the MAC addresses of other slave controllers in the same group, the slave controller array serial numbers and the physical areas where the LED groups are located are respectively and one-to-one corresponding. In the implementation process, each other sub-controller in the group can also bind the IP address and the MAC address by itself and transmit the binding information back to the switch through the target sub-controller. Therefore, the IP address automatic binding of the sub-controller is realized, and the manual intervention degree is reduced.

In order to optimize the utilization efficiency of the bandwidth and reduce the bandwidth waste, in an alternative embodiment, after step S300, the method further includes: after cascade connection of each sub-controller is completed, the sub-controller currently in a working state is identified; the total bandwidth of the switch is distributed according to the number of the sub-controllers in the working state, and the unit bandwidth is obtained; the total bandwidth is distributed to each sub-controller in an operating state according to the size of the unit bandwidth, and the total bandwidth is not distributed to the sub-controllers in a non-operating state. Specifically, after each sub-controller completes cascading, the current working state (in working state or non-working state) of each sub-controller can be identified through data interaction, at this time, the total bandwidth of the switch can be allocated according to the number of sub-controllers in working state, specifically, each sub-controller in working state can obtain each bandwidth in an average allocation mode, and the sub-controllers in non-working state do not occupy bandwidth any more. The total bandwidth of the switch is distributed to each sub-controller in an operating state according to the requirement. Compared with the prior art, the method for fixing the bandwidth can fully utilize the total bandwidth, so that the total bandwidth is completely distributed to the sub-controllers participating in the work, the utilization efficiency of the total bandwidth is improved, and the waste of the bandwidth is reduced.

Because each sub-controller is connected with the switch in a cascade manner, the switch needs to transit through the sub-controllers between the switch and the target sub-controller when transmitting the data packet to the target sub-controller, when one of the sub-controllers fails, the target sub-controller can not receive the data packet transmitted by the switch, and in order to avoid the situation that the data packet cannot be received caused by the failure of one of the sub-controllers, in an alternative embodiment, adjacent groups of (parallel) sub-controllers are connected end to end (see fig. 2); for the mode of series connection, each sub-controller is connected in series in turn, so that the end-to-end connection of adjacent sub-controllers can be realized. In transmitting the LED driving data packet, the switch transmits the data packet bi-directionally, that is, the switch starts to transmit the data packet of the same content to each of the sub-controllers from the first sub-controller and the last sub-controller (as shown by the broken arrow line in fig. 2), thereby forming two data transmission links, and at this time, even if one or more of the sub-controllers in one of the data links fails, the target sub-controller can receive the data packet through the other data link. Therefore, the situation that the subsequent sub controllers cannot work due to the fact that one or more sub controllers are in fault is avoided. And because the switch transmits the data packet through the bidirectional data link, when one of the sub-controllers has a fault, the fault sub-controllers can be conveniently and rapidly arranged through the bidirectional data link for opposite transmission, for example, the fault sub-controllers can be positioned through the front-stage and rear-stage data transmission conditions, and specifically, the front-stage and rear-stage sub-controllers of the fault sub-controllers can normally receive the data packet and drive the LEDs to emit light, so that the fault sub-controllers can be positioned very efficiently and accurately.

In an alternative embodiment, when the switch transmits in opposite directions through the bidirectional data link, each sub-controller preferentially processes the data received first, so that the data processing speed and the response speed are improved.
