Description

Technical Field

[0001] The embodiments of the present application relate to the field of wind turbine address control technology, and in particular to a wind turbine address writing method and a wind turbine address writing system. Background Art

[0002] Fan Filter Unit (FFU) is an air filtration device widely used in clean rooms, laboratories, hospitals and other places to provide a clean and healthy air environment.

[0003] To support the production of high-tech products, cleanrooms are being constructed and implemented in large numbers across the country, and FFUs are widely used. To facilitate factory monitoring of cleanrooms, the most common practice is to connect numerous FFUs via RS-485 and Ethernet, controlling them from a central control room computer. This requires assigning each FFU a unique address to ensure one-to-one correspondence on the computer interface.

[0004] When writing addresses to FFUs, on-site construction personnel need to carry a handheld device close to the FFU and set the address for each FFU one by one, that is, write the address of the FFU to the FFU controller. However, when setting addresses, it is easy to have duplicate addresses or missed addresses, which makes troubleshooting and maintenance difficult. In addition, the controller inside the FFU is generally installed in the technical mezzanine of the clean room. Due to the large number of equipment and pipelines in the technical mezzanine, it is very inconvenient for personnel to move. On-site construction personnel need to wear stuffy dust-proof clothing to avoid the dust-free environment of the clean room, and they also need to climb to the side of the FFU one by one, making it difficult for construction personnel to write addresses for multiple FFUs.

[0029] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0030] This application is applicable to addressing an FFU fan group consisting of multiple FFUs, and is also applicable to addressing multiple fans of other types, for example, addressing a BFU fan group consisting of multiple BFUs (Blowing Filter Units), or addressing a fan group consisting of multiple FFUs and BFU fans.

[0031] Figure 1 The schematic diagram of the application scenario of the wind turbine address writing method provided by the embodiment of the present application is shown. Figure 1 , n wind turbines all include a first network port, a second network port, a microcontroller unit MCU and a 485 communication circuit module; the first network port of the first wind turbine and the second network port of the nth wind turbine are both connected to the host computer via a communication network cable. When i is greater than 1, the first network port of the i-th wind turbine and the second network port of the i-1th wind turbine are connected via a communication network cable.

[0032] The host computer may be a handheld device that can be used to set the fan.

[0033] The communication network cable includes an RS485 communication cable and a first signal cable. The communication network cable is used to transmit signals between two devices. The RS485 communication cable is used to transmit RS485 signals to establish a 485 connection between the two devices. The first signal cable is used to transmit a level signal to establish a first communication connection between the two devices. A 485 connection is established between the host computer and each of the n wind turbines. Specifically, the communication network cable is connected to the RJ45 port of the host computer.

[0034] The communication network cable is preferably a Category 5e network cable. The two core wires of any pair of twisted pairs in the Category 5e network cable are respectively used as the communication line of communication port A and the communication line of communication port B that comply with the RS485 communication protocol to implement 485 connection. Specifically, blue and blue-white twisted pairs can be selected as 485 communication lines and set up in accordance with the TIA / EIA-568B international standard; any one of the remaining twisted pairs in the Category 5e network cable is used as the communication signal line (that is, the first signal line) to implement the automatic addressing function. Of course, multiple pairs can also be used.

[0035] Furthermore, the internal structure of each fan is described.

[0036] The first network port of the fan is connected to the first communication network cable, and is used to receive the RS485 signal and level signal transmitted by the first communication network cable, and transmit the received level signal to the MCU of the fan, and transmit the received RS485 signal to the 485 communication circuit module of the fan.

[0037] The MCU communicates with the first network port through PIN3 of the Category 5e network cable and with the second network port through PIN4. After receiving the level signal from the host computer, PIN3 is set high.

[0038] 485 communication circuit module, connected to the MCU, is used to process the received RS485 signal and send it to the MCU.

[0039] The MCU is used to process the received level signal and / or RS485 signal, and to generate a level signal and / or an initial RS485 signal. It is also used to transmit the generated initial RS485 signal to the 485 communication circuit module and transmit the generated level signal to the second network port.

[0040] When the generated level signal is transmitted to the second network port, PIN4 is set high.

[0041] The 485 communication circuit module is further used to generate an RS485 signal according to the initial RS485 signal and send the generated RS485 signal to the second network port.

[0042] The second network port is connected to the second communication network cable, and is used to transmit the level signal generated by the MCU to the first signal line of the second communication network cable, and to transmit the RS485 signal generated by the 485 communication circuit module to the RS485 communication line of the second communication network cable.

[0043] The 485 communication circuit modules of multiple fans form a parallel structure. When the host computer is electrically connected to the parallel structure, after the host computer sends the RS485 signal, the 485 communication circuit modules of n fans can all receive the RS485 signal sent by the host computer.

[0044] Please combine Figure 1 and Figure 2 , the specific structures of the first network port, the second network port, the micro control unit MCU and the 485 communication circuit module are described. Figure 2 P1 shows a specific structural diagram of the MCU, P2 shows a specific structural diagram of the 485 communication circuit module, P3 shows a circuit connection diagram for realizing the communication function between the MCU and the network port, and P4 shows a specific structural diagram of the first network port.

[0045] The PB04 and PB06 pins of the MCU are connected to the D1 and RO pins of the 485 communication circuit module respectively to realize the signal sending function of 485TX and the signal receiving function of 485RX respectively.

[0046] The PB03 pin of the MCU is connected to port 5 and port 13 of the first network port to implement the level signal transmission function of S1. The circuit structure for implementing signal transmission between the PB03 pin and ports 5 and 13 can be specifically referred to as P3.

[0047] Port A of the 485 communication circuit module is connected to port 7 and port 15 of network port 1 to realize communication of communication port A connected by 485; port B of the 485 communication circuit module is connected to port 3 and port 11 of network port 1 to realize communication of communication port B connected by 485.

[0048] It should be noted that the specific structure of the second network port is similar to that of the first network port. Therefore, the structure of the second network port for implementing communication can refer to the above description of the first network port and will not be repeated here.

[0049] In actual use, since the fan groups are connected in a hand-in-hand structure via the 485 bus, the two core wires of any pair of twisted pairs in the Category 5e network cable are actually used as A and B of the 485. The remaining twisted pairs are non-functional. For the sake of convenience, we choose blue and blue-white twisted pairs as 485 communication lines. According to the TIA / EIA-568B international standard, these are PIN4 and PIN5, which we can name D1 / D2 respectively. Our innovation is to use any one of the remaining twisted pairs as the communication signal line for the automatic dialing function. Of course, multiple pairs can be used, and the principle is the same. For the sake of convenience, we choose PIN1 orange and white as the automatic dialing communication line. Since the fan groups are connected in a hand-in-hand structure via the 485 bus, each fan must have two RJ45 ports, one as the input port and the other as the output port. In addition, to facilitate construction by on-site workers, the definitions of these two input and output ports are arbitrary. Thus, both RJ45 ports have pins corresponding to PIN 1 of the twisted pair cable. For ease of description, these are designated as P1 and P9, respectively. In the PCB design, the communication chip has two GPIO ports, D3 and D4, which connect to P1 and P9, respectively. Thus, pins D1 and D2 on the communication chip correspond to 485+ and 485-, respectively, while pins D3 and D4 correspond to P1 and P9 of the RJ45 port, respectively. When the fan unit is connected to the network cable, P1 and P9 are both connected to the orange and white wires on PIN 1 of the network cable. When the network cable is also plugged into the RJ45 port of the handheld, all the hardware for the write address function is ready: P1 of the handheld is connected to D3 of the fan controller chip via PIN 1 of the network cable. Example

[0050] Figure 3 The flow chart of the wind turbine address writing method provided by the embodiment of the present application is shown. Figure 3 The fan addressing method is applied to a fan group. The fan group has a communication connection with a host computer. The fan group includes n fans arranged in sequence, where n is an integer greater than 1. The fan addressing method includes:

[0051] S110 , the first wind turbine among the n wind turbines receives the initial address information and the first write instruction sent by the host computer.

[0052] The initial address information may include group information and number information, such as "G1F1 (group 1 number 1)".

[0053] The upper computer, in response to the address writing operation, obtains the initial address information and generates the first write instruction, and sends the initial address information and the first write instruction to the first wind machine among the n wind machines, so that the i-th wind machine writes the i-th address information corresponding to the i-th wind machine, wherein the i-th address information is related to the initial address information, and i is sequentially taken from 1 to n.

[0054] The construction personnel trigger the address writing operation on the host computer. The initial address information can be the address information independently input by the user through the buttons or touch screen on the host computer, or can be generated by the host computer itself in response to the address writing operation.

[0055] S120 , the i-th wind turbine among the n wind turbines performs the following steps, wherein i is sequentially incremented from 1 to n.

[0057] For example, the first address information of the first wind turbine is G1F1, and the second address information can be obtained by performing character operation on G1F1, and the second address information of the second wind turbine can be G1F2.

[0058] S122: If i does not get n, generate the (i+1)th write instruction and send the (i+1)th write instruction to the (i+1)th wind turbine.

[0059] After S122 is executed, i is incremented by 1 and the process jumps to S121.

[0060] S123: If i gets n, the address writing of the wind turbine group is completed.

[0061] To save system operating costs, preferably, before S110, the wind turbine address writing method further includes:

[0062] S101, n wind turbines receive address writing instructions sent by a host computer through a 485 connection, and enter address writing mode in response to the address writing instructions.

[0064] S121a, sending the i-th address information to the host computer via the 485 connection.

[0065] S121b, exit the write address mode.

[0066] The fan enters the address writing mode through the address writing instruction, and exits the address writing mode after completing the address writing, which can save the operating cost of the system.
