[0001] The utility model relates to the technical field of LED display control, in particular to an LED playback display control system. Background Art

[0002] With the intelligent development of LED technology, LED playback control systems are widely used in scenic spots and buildings, such as the "light show" in the city. Taking the "light show" in the city as an example, when deploying the LED playback control system, countless LEDs need to be laid on the facades of high-rise buildings, and the LEDs are grouped. Different sub-controllers control different groups of LEDs respectively. The sub-controllers are usually installed on the top floor of the high-rise building, or on the equipment positions (outside the building) of different floors. Each sub-controller is uniformly dispatched and controlled by the host (switch).

[0003] In the prior art, multiple sub-controllers are evenly allocated the corresponding bandwidth from the switch. However, with the increase in building complexes and the surface area of ​​high-rise buildings, the LED lamps deployed by the LED playback control system are also growing geometrically, and more sub-controllers are needed to control the LED lamps, which will lead to a decrease in the bandwidth allocated to each sub-controller; and the animation effects of the "light show" are becoming more and more complex, which requires a sharp increase in the amount of data transmitted between the main control computer and each sub-controller. The bandwidth allocated to each sub-controller obviously cannot meet the timeliness requirements of data transmission, resulting in a freeze in the city's "light show" performance.

[0036] In order to improve the connection mode between the switch and each sub-controller and improve the data transmission efficiency, this embodiment discloses an LED playback display control system, please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of an LED playback display control system disclosed in this embodiment. The LED playback display control system includes: a switch 1 and multiple sub-controllers 2, wherein:

[0037] Please refer to Figure 1 The switch 1 is connected between the main control computer 3 and the plurality of sub-controllers 2. The switch 1 is used to transfer the LED playback program data provided by the main control computer 3 to the plurality of sub-controllers 2. In a specific embodiment, the main control computer 3 of the playback display control system can realize the on and off control of the landscape LED according to the set program. Specifically, the main control computer 3 sends the LED playback program data of each LED lamp to the switch 1, and the LED playback program data is sent to the corresponding sub-controller 2 through the switch 1. The sub-controller 2 drives the corresponding LED group to light up or turn off according to the corresponding LED playback program, thereby realizing the "light show".

[0038] Each of the multiple sub-controllers 2 is connected to the landscape LEDs of its own group, so as to control the LEDs of its own group to switch on and off according to the LED playback program data. Figure 2 , Figure 2 This is a schematic diagram of an arrangement of LED lamps disclosed in this embodiment. The LED lamps 4 are divided into several groups (such as Figure 2The LED lamps 10 are arranged on the facades of buildings. Of course, in some embodiments, the LED lamps 10 can also be arranged on objects such as bridges and hillsides. Each group of LED lamps 4 is controlled by the corresponding sub-controller 2. Generally speaking, each sub-controller 2 realizes the orderly lighting of each group of LED lamps 4 through a control program associated with the timing, thereby achieving the effect of a "light show". In an optional embodiment, the landscape LEDs are divided into multiple groups to form an LED array, and each sub-controller 2 is arranged to correspond to each group of landscape LEDs in space, thereby facilitating the correspondence between the sub-controller and the LED lamps 4 in the physical space, and facilitating user operation and control.

[0039] Please refer to Figure 1 and Figure 3 , Figure 3 This is a schematic diagram of a sub-controller structure disclosed in this embodiment. In a specific embodiment, each sub-controller 2 includes a first network interface 21 and a second network interface 22. The second network interface 22 of the i-th sub-controller 2 is connected to the first network interface 21 of the i+1-th sub-controller 2 to connect multiple sub-controllers 2 end to end, where i≥1. In this embodiment, by configuring the second network interface 22, each sub-controller can be connected in series. In the specific implementation process, the first network interface 21 and the second network interface 22 can be set nearby.

[0040] Please refer to Figure 1 , the first sub-controller 2 is connected to the switch 1 through the first network interface 21 to transmit the LED playback program data to the first-to-last sub-controller 2 in the forward direction. The first-to-last sub-controller 2 is connected to the switch 1 through the first network interface 21 to transmit the LED playback program data to the first sub-controller 2 in the reverse direction. In the specific implementation process, the first network interface 21 and the second network interface 22 can be traditional Ethernet interfaces, and the forward and reverse transmission of data is performed through network cables or optical fibers. It should be noted that the forward and reverse transmission of data based on Ethernet is itself a prior art and will not be repeated here. In this embodiment, the LED playback program data is transmitted through two channels, forward and reverse, which can improve the data transmission efficiency.

[0041] In the specific implementation process, multiple sub-controllers 2 are divided into N groups by column, and each group is connected in series with several sub-controllers 2 through the first network interface 21 and the second network interface 22, where N≥2; each group of sub-controllers 2 is connected in parallel to the network interface of the switch 1. Figure 1, the sub-controller 2 is connected to the adjacent sub-controller 2 through the first network interface 21 and the second network interface 22, thereby realizing the serial connection of each group of sub-controllers; the first sub-controller in each group of sub-controllers 2 is connected to the network interface of the switch 1 through its own first network interface 21, thereby realizing the parallel connection of each group of sub-controllers. In this embodiment, after each group of sub-controllers is connected to the switch 1, the switch 1 can start to transmit the LED playback program data to each group of sub-controllers through the first sub-controller in each group, that is, multiple channels are used to synchronously transmit data to the sub-controllers. For example, when the sub-controllers are divided into N groups, there are N sub-controllers connected to the switch 1. At this time, the switch 1 can simultaneously transmit the LED playback program data through N channels, thereby further improving the data transmission efficiency.

[0042] In order to realize data interaction between different groups, when a sub-controller in the group fails, data transmission can still be realized without affecting other sub-controllers in the group receiving LED playback program data and driving LED lamps 4. In an optional embodiment, please refer to Figure 1 , the last sub-controller 2 of the kth group is connected to the last sub-controller 2 of the k+1th group through the second network interface 22, where k≥1; the first sub-controller 2 of each group is connected to the switch 1 through the first network interface 21. That is, the last sub-controllers of adjacent groups are connected in series through the second network interface 22. At this time, when a sub-controller in the kth group fails, although its subsequent sub-controllers cannot transmit LED playback program data through the kth group, they can receive LED playback program data through the k+1th group, so that the subsequent sub-controllers of the failed sub-controller in the kth group can still receive LED playback program data and drive the LED lamp 4.

[0043] In a specific embodiment, each group of first sub-controllers 2 receives LED playback program data (such as Figure 1 The LED playing program data is transmitted to the adjacent sub-controller 2 through the respective second network interface 22. The details are as follows:

[0044] In one embodiment, the last sub-controller 2 of the kth group receives the LED playing program data transmitted by the adjacent sub-controller 2 of the group, or receives the LED playing program data transmitted by the last sub-controller 2 of the k+1th group through the second network interface 22. Specifically, since the data content transmitted by each group of sub-controllers is the same, any sub-controller can receive the LED playing program data through the previous sub-controller of the group, or can receive the LED playing program data transmitted by the next group of sub-controllers through the next sub-controller of the group. In the specific implementation process, each sub-controller can select one to receive according to the data transmission rate, that is, each sub-controller can preferentially receive the LED playing program data transmitted first according to the order of data transmission, thereby improving the data transmission efficiency. In addition, each sub-controller also has two transmission channels: the previous sub-controller in the same group, the next sub-controller in the same group, and the next group of sub-controllers, which has one more data transmission channel compared with the prior art.

[0045] In another embodiment, the last sub-controller 2 of the k+1th group receives the LED playback program data transmitted by the adjacent sub-controller 2 of the group, or receives the LED playback program data transmitted by the last sub-controller 2 of the kth group through the second network interface 22. Specifically, since the data content transmitted by each group of sub-controllers is the same, any sub-controller can receive the LED playback program data through the previous sub-controller of the group, or can receive the LED playback program data transmitted by the previous group of sub-controllers through the next sub-controller of the group. In the specific implementation process, each sub-controller can select one to receive according to the data transmission rate, that is, each sub-controller can receive the LED playback program data transmitted first according to the order of data transmission, thereby improving the data transmission efficiency. In addition, each sub-controller also has two transmission channels: the previous sub-controller in the same group, the next sub-controller in the same group, and the previous group of sub-controllers, which has one more data transmission channel compared with the prior art.

[0046] For the convenience of understanding by those skilled in the art, please refer to Figure 1Taking the second column (group) of sub-controllers as an example, the third sub-controller in the second column fails (as indicated by a cross). When the sub-controller is not faulty, the (4th, 5th...) sub-controllers at the subsequent stage of the sub-controller all transmit the first data packet via the third sub-controller. After the third sub-controller fails, the (4th, 5th...) sub-controllers at the subsequent stage can no longer receive the LED playback program data via the third sub-controller, which will cause the (4th, 5th...) sub-controllers at the subsequent stage to be unable to drive the LED lamps, thereby causing a large area of ​​LED lamps to be unable to be driven. In the present embodiment, when the third sub-controller in the second column fails, the LED playback program data is transmitted to the last sub-controller in the second column by its adjacent group, that is, the first column (group), so that the last sub-controller in the second column transmits the LED playback program data in reverse to the third sub-controller in the second column, that is, the subsequent sub-controllers of the third sub-controller in the second column can transmit the LED playback program data through the adjacent group, thereby ensuring that these sub-controllers can all receive the data packet, avoiding the occurrence of large-scale LED on and off failures.

[0047] In order to improve the cascade efficiency of the sub-controllers in a group and improve the correspondence between the sub-controllers and the LED lamps, in an optional embodiment, the device serial number of the sub-controllers 2 in the same group increases from the first sub-controller 2 to the last sub-controller 2; the IP address of the sub-controller 2 in the same group increases from the first sub-controller 2 to the last sub-controller 2, and the increment of the IP address serial number is the same as the increment of the device serial number. For details, please refer to Figure 1 , Figure 1 Each dotted box in the figure represents a group of sub-controllers, and the sub-controllers in the group are arranged in order, such as 01, 02, 03, 04, etc. The arrangement order of the multiple IP addresses preset by the switch corresponds to the order of the serial numbers of the sub-controllers, and the increment of the serial number of the IP address is the same as the increment of the device serial number. For example, the last digit or the last two digits of the IP address are incremented in sequence. Therefore, the IP address is associated with the serial number of the sub-controller in sequence. In the process of allocating IP addresses to each sub-controller, after determining the IP address and serial number of a certain sub-controller in a group (for example, No. 01), at this time, for other sub-controllers in the sub-controller group, the IP address of each sub-controller can be determined according to the corresponding IP address and sub-controller serial number in order, thereby automatically binding the IP address and sub-controller serial number of each sub-controller in the group. Automatic binding of sub-controller IP addresses is achieved, reducing human errors caused by manual binding.

[0048] In a specific embodiment, the switch 1 is also used to allocate bandwidth required for data interaction to multiple sub-controllers 2; in order to optimize bandwidth utilization efficiency and reduce bandwidth waste, in an optional embodiment, the number of sub-controllers in the multiple sub-controllers 2 that are in working state is M1, and the number of sub-controllers that are in non-working state is M2; the bandwidth of the switch 1 is occupied by M1 sub-controllers 2 in working state, and the number of sub-controllers 2 in non-working state is M2 and does not occupy bandwidth. That is, in this embodiment, the switch 1 allocates bandwidth based on the number of sub-controllers in operation, rather than allocating bandwidth based on the total number of sub-controllers (regardless of whether they are in working state) in the prior art. Compared with the allocation method of the prior art, the bandwidth utilization efficiency can be improved and bandwidth waste can be reduced. Assuming that the total bandwidth of the switch 1 is M, the comparison is as follows:

[0049] In the bandwidth allocation method of the prior art, the bandwidth allocated to each sub-controller 2 is M / (M1+M2), that is, the bandwidth that the sub-controller 2 in the working state can use for data interaction is M / (M1+M2);

[0050] When the bandwidth allocation method of this embodiment is adopted, the M2 sub-controllers in the non-working state do not occupy the bandwidth, and the total bandwidth M of the switch is occupied by the M1 sub-controllers in the working state. At this time, the bandwidth that the sub-controller 2 in the working state can use for data interaction is M / M1.

[0051] By comparison, it can be seen that in this embodiment, the sub-controllers in working state are allocated more bandwidth, thereby improving the bandwidth utilization efficiency of the switch.

[0052] According to an LED playback display control system disclosed in an embodiment of the utility model, each sub-controller includes a first network interface and a second network interface, and the second network interface of the i-th sub-controller is connected to the first network interface of the i+1-th sub-controller, so that the multiple sub-controllers can be connected end to end, wherein i≥1; the first sub-controller and the penultimate sub-controller respectively receive LED playback program data from the switch through the first network interface, and transmit the data between the multiple sub-controllers, so that there are at least two channels for parallel transmission of LED playback program data at the switch, and each sub-controller can receive the LED playback program data from the first sub-controller or the penultimate sub-controller nearby, that is, the sub-controller close to the penultimate sub-controller can receive the data output by the penultimate sub-controller; thereby, the connection method between the switch and each sub-controller is improved, the data transmission efficiency is improved, and the reliability of data transmission is further guaranteed due to the increase in data transmission channels.
