[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific diagrams.

[0026] See also Figure 1 , the figure shows a data storage and transmission method for a wood-based panel production line, which includes the following steps:

[0027] Step S10, construct a UDT data structure for storing the specific information of each board, as shown in Table 1, to record data in a more unified and standardized manner. Based on this, a complete file is established for each produced board, in which the first multiple signal bits are used to mark the status of the board, and the remaining analog quantities record the time, specifications, and batch of the board production, which are used for transmission during the operation of the artificial board production line.

[0028] Table 1: UDT data structure

[0029]

[0030] Step S20, construct a DB data block for storing board production information according to the UDT data structure, wherein the DB data block uses the UDT array Array[0...N] (N is an integer and ≥3) to identify different equipment of the wood-based panel production line, wherein Array[X] (X is an integer and 0≤X≤N) represents a data block for storing board production information of the Xth device. In this embodiment, N in the UDT array can be set to 99. For the post-processing conveyor line in the wood-based panel industry, although the layout of different equipment varies greatly for each project due to reasons such as plant layout and output size, the main components are basically the same, mainly covering three main parts: conveying and sorting line, cooling plate turning rack, and lifting and stacking table.

[0031] Table 2: DB data block

[0032] Empty BoardData No-load data FromPress BoardData Actual data of press export FromHMI BoardData Operation interface setting data ActRun BoardData Actual data MainLine Array[0...99]of"BoardData" Mainline data Cooler 1 Array[0…99]of"BoardData" 1# Flip rack data Cooler 2 Array[0…99]of"BoardData" 2# flip rack data Cooler 3 Array[0...99]of"BoardData" 3# flip rack data Cooler 4 Array[0...99]of"BoardData" 4# flip rack data Stack 1 Array[0...99]of"BoardData" 1# Stacking station data Stack 2 Array[0...99]of"BoardData" 2# Stacking station data SP Array[0...99]of Bool Pulse signal point

[0033] Among them, the use of UDT array Array[0...99] can reserve space for 100 working points for the wood-based panel production line, which can fully meet the requirements of the actual equipment on site and leave enough room for expansion. You only need to call the corresponding real number in [0...99] to conveniently write and read the specific data of the corresponding actual position board on site.

[0034] Step S30, numbering the board positions on the main production line according to the actual layout of the equipment of the wood-based panel production line, such as Figure 2 As shown, all the equipment on the wood-based panel production line are correspondingly associated with the UDT array Array[0...N] according to the numbering result;

[0035] Step S40, when the finished board produced by the press enters the wood-based panel production line, the production status of the finished board is detected by the detection sensors equipped on each device on the wood-based panel production line, and the detection signal is saved in the data block corresponding to the UDT array Array[0...N].

[0036] In step S40, when the finished board produced by the press enters the conveying and sorting line, see Figure 3, you can select from the recipe or manually fill in the data, write the main line data block MainLine[1] through the rising edge signal, and then activate the data transmission MainLine[1]→MainLine[2]→MainLine[...] by detecting the sensor signal according to the actual order of the equipment, such as Figure 4 shown.

[0037] When the finished board enters the cooling rack, the data transfer is activated every time the cooling rack flips one grid. The data on the entrance side is written into the first grid Cooler x[1] and the data of the current grid is transferred to the next grid Cooler x[Int+1]. According to the actual size of the cooling rack on site, the last grid data Cooler x[x] that can be stored is written into MainLine[x] on the board exit side. For example, Figure 4 and Figure 5 For example, for a 90-grid flip rack, there are 45 grids above the equipment baseline, and the actual storage capacity is 44 boards. Each time a board is flipped, the data of the 44th grid will be transferred to the data area on the board output side.

[0038] When the finished board enters the lifting and stacking table, the number of times it enters is recorded, and each time the board exit data is written into the stacking data MainLine[x]→Stack x[Int+1], the data of each board in the entire stack will be retained, and Stack x[..] can be passed to the storage area as a whole.

[0039] Step S50, when the HMI interface needs to display data, the input INT value is obtained, and the specific board information to be displayed is found from the UDT array Array[0...N] according to the input INT value and the HMI interface is displayed.

[0040] In step S50, see Figure 7 , get the input INT value, and find the specific board information to be displayed from the UDT array Array[0...N] according to the input INT value and display it on the HMI interface, including the following steps:

[0041] Step S51, constructing an INT value input channel for the HMI interface for obtaining an INT value, and limiting the maximum number of digits of the INT value to four digits;

[0042] Step S52, obtaining the INT value input by the user through the INT value input channel, and splitting the INT value into the first two digits and the last two digits, wherein the first two digits are used as a calibration pointer for finding the equipment of the wood-based panel production line, and the last two digits are used as a specific pointer for finding specific panel information from the calibrated equipment;

[0043] Step S53, calibrating the equipment of the wood-based panel production line according to the first two digits of the INT value, and finding specific panel information from the calibrated equipment according to the last two digits of the INT value;

[0044] Step S54, importing the found specific board information into the HMI display channel, so that the HMI interface displays the specific board information, so that the implementation parameters of all position boards can be arbitrarily displayed using only one set of UDT data type channels.

[0045] Due to the simplification of addressing addresses, it is easier for HMI (human-machine interface) to call and display data stored in the program, especially when adapting to non-Wincc systems, which can greatly reduce the number of communication channels occupied and save software costs.

[0046] The data storage and transmission method of the artificial board production line of the present invention also includes step S60, constructing a storage DB data block for storing the storage information of the finished boards, and the storage DB data block uses the UDT array Array[1...A,1...B,0...N] (A, B are integers and ≥2) to identify the finished boards placed in the storage area.

[0047] Compared with the previous use, the storage structure of UDT array Array[1...A,1...B,0...N] can better record the specific data of products for storage, because the pointer has strong scalability and can be used as Array[..,..,..] for multi-column addressing. For example, in a middle rush area with 10 columns and 10 rows, Figure 8 As shown, a storage DB data block of a UDT array Array[1...10,1...10,0...99] is established, and then the data of a whole stack of boards can be written to the intermediate storage location by selecting rows and columns, such as Fig. 9 As shown, compared with the past, the stored board data can be accurately stored for each block, making it easier to retrieve data on the HMI interface.

[0048] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
