Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of wind turbine address control, 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, a large number of dust-free workshops are being built and used across the country, among which FFU is widely used. In order to facilitate factory monitoring of clean rooms, the most common practice is to connect a large number of FFUs together through RS-485 and Ethernet, and control them through computers in the central control room. In this way, each FFU needs to be given a unique address so that it can correspond one to one on the computer interface.

[0004] When writing addresses to FFUs, on-site construction personnel are required to carry a handheld device close to the FFU to set addresses for each FFU one by one, that is, to write the address of the FFU into the controller of the FFU. However, when setting addresses, it is easy to have repeated address settings or missed addresses, resulting in difficulties in troubleshooting and maintenance. 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 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 dust-free workshop, 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.

DETAILED DESCRIPTION

[0022] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the 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 by the embodiments set forth herein.

[0023] This application is applicable to addressing an FFU fan group composed of multiple FFUs, and is also applicable to addressing multiple fans of other types, for example, addressing a BFU fan group composed of multiple BFUs (Blowing Filter Units), or addressing a fan group composed of multiple FFUs and BFU fans.

[0024] Figure 1 A schematic diagram showing an application scenario of the wind turbine address writing method provided in an 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 n-th wind turbine are both connected to the host computer via a communication network cable, and when i is greater than 1, the first network port of the i-th wind turbine and the second network port of the i-1-th wind turbine are connected to a communication network cable.

[0025] The host computer may be a handheld device that can be used to set the fan.

[0026] 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 so that the two devices establish a 485 connection. The first signal cable is used to transmit a level signal so that the two devices establish a first communication connection. A 485 connection is established between the host computer and the n wind turbines. Specifically, the communication network cable is connected to the RJ45 port of the host computer.

[0027] The communication network cable is preferably a Category 5e network cable, and the two core wires of any pair of twisted pair cables 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 realize 485 connection. Specifically, blue and blue-white twisted pair cables 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 pair cables in the Category 5e network cable is used as a communication signal line (that is, the first signal line) to realize the automatic addressing function, and of course multiple cables can be used.

[0028] Furthermore, the internal structure of each fan is described.

[0029] The first network port of the fan is connected to the first communication network cable, and is used to receive the RS485 signal and the 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.

[0030] The MCU communicates with the first network port through PIN3 of the Category 5e network cable and communicates with the second network port through PIN4. After receiving the level signal from the host computer, PIN3 is set high.

[0031] The 485 communication circuit module is connected to the MCU and is used to process the received RS485 signal and send it to the MCU.

[0032] The MCU is used to process the received level signal and / or RS485 signal, and to generate the level signal and / or the initial RS485 signal, and 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.

[0033] When the generated level signal is transmitted to the second network port, PIN4 is set high.

[0034] The 485 communication circuit module is also used to generate an RS485 signal according to the initial RS485 signal, and send the generated RS485 signal to the second network port.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] The PB04 pin and the PB06 pin of the MCU are respectively connected to the D1 pin and the RO pin of the 485 communication circuit module to respectively realize the sending signal function of 485TX and the receiving signal function of 485RX.

[0039] The PB03 pin of the MCU is connected to the port 5 and the port 13 of the first network port to realize the level signal transmission function of S1. The circuit structure for realizing the signal transmission between the PB03 pin and the port 5 and the port 13 can be specifically referred to as P3.

[0040] 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 of the 485 connection; 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 of the 485 connection.

[0041] 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 to implement communication can refer to the above description of the first network port, which will not be repeated here.

[0042] In actual use, since the fan group is connected through the 485 bus in a hand-in-hand structure, the two core wires of any pair of twisted pairs in the Category 5e network cable are actually used as A and B of 485, and the remaining twisted pairs are non-functional. For the convenience of explanation, we use 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 of the automatic dialing function. Of course, multiple pairs can also be used. The principle is the same. Here, for the convenience of description, we use PIN1 orange and white as the automatic dialing communication line; since the fan group is connected through the 485 bus in a hand-in-hand structure, each fan must have two RJ45 ports, one as the input port and the other as the output port, and in order to facilitate the construction of on-site workers, the definition of these two input and output ports is arbitrary. In this way, there will be pins corresponding to the twisted pair PIN1 on both RJ45 ports, which are defined as P1 and P9 for the convenience of description. In the PCB board design, the communication chip has two GPIO ports D3 and D4, which are connected to P1 and P9 respectively. In this way, the communication chip has pins D1 and D2 corresponding to 485+ and 485- respectively, and pins D3 and D4 corresponding to P1 and P9 of the RJ45 port respectively. When the fan unit is connected to the network cable, P1 and P9 are connected to the orange and white wires of PIN1 of the network cable. When the network cable is also inserted 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 through PIN1 of the network cable.

[0043] Embodiment 1: Figure 3 A schematic diagram showing the flow of the wind turbine address writing method provided in 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.

[0050] S122, if i does not get n, generate the i+1th write instruction, and send the i+1th write instruction to the i+1th wind turbine.

[0051] After S122 is executed, i is incremented by 1 and the process jumps to S121.
