[0027] Embodiment:

[0028] Please refer to Figs. 1-3 The present application provides a technical solution:

[0029] A multi-dimensional data hyper-dimensional chessboard information management system, comprising an information collection end 10, wherein:

[0030] The information collection end 10 is provided with at least two groups, the output end of the information collection end 10 and the input end of the switch 20 are in communication connection, for receiving external optical fiber signals and converting them into electrical signals and then conveying them to the switch 20, the output end of the switch 20 and the input end of the router 30 are in communication connection, for forwarding the received electrical signals to the router 30, the router 30 is used for connecting Ethernet and sending to the data host 40 through Ethernet.

[0031] In this embodiment, the model of switch 20 is TP-Link TL-SG108PE series, and the model of router 30 is MikroTik RB760iGS. The switch 20 is directly connected with the LAN port / descending port of the router 30 through the ascending port, and is connected by Cat6a network cable or optical fiber. The VLAN needs to be divided on the switch 20, for example, the port of the information collection end is divided into a dedicated VLAN, and the router 30 needs to be configured with static route or dynamic routing protocol to point the subnet of the switch 20 to the corresponding interface.

[0033] The information collection end 10 includes a 485 bus 12, and at least two groups of photoelectric collection units 11 are connected in parallel on the 485 bus 12. The photoelectric collection unit 11 includes a fiber communication unit and a 485 communication unit, and the data communication port of the fiber communication unit and the data communication port of the 485 communication unit are connected through a conversion circuit.

[0034] The fiber port of the fiber communication unit is connected with an external optical fiber, the 485 communication serial port of the 485 communication unit is electrically connected with the 485 bus 12, the conversion circuit is used to switch the sending and receiving of data between the fiber communication unit and the 485 communication unit, the differential output pins A / B of the 485 communication unit are directly connected in parallel to the 485 bus 12 as a communication node on the bus, the bus uses twisted pair to transmit differential signals, all nodes share the same physical link, and multi-node communication is realized through bus topology.

[0035] In this embodiment, the fiber communication unit adopts a 1×9 packaged dual-fiber TTL optical module, and the 485 communication unit adopts an RS-485 transceiver. The model of the fiber communication unit is ET-2510 series of Yichuangtong, the fiber communication unit converts the optical signal input by the external optical fiber into a TTL level electrical signal, and interacts with the RS-485 communication unit through the conversion circuit. The model of the 485 communication unit is SN65HVD72 of TI, which is used to convert the TTL level signal into an RS-485 differential signal to drive the multi-node communication on the 485 bus. The receiving end of the fiber communication unit is connected with the optical fiber, and the optical signal is converted into an electrical pulse through an internal photodiode. The output pin of the fiber communication unit transmits the electrical signal to the conversion circuit, the 485 communication unit receives the TTL signal from the fiber communication unit, and generates a differential signal through an internal drive circuit. This is the process of receiving external optical signals in this embodiment, and the process of sending optical signals is opposite.

[0036] In this embodiment, the optical fiber communication unit has a light transmitting end TX and a light receiving end RX, the light transmitting end TX is used for transmitting optical signals to the outside, the light receiving end RX is used for receiving optical signals from the outside, and the optical fiber communication unit also has a signal transmitting pin TD and a receiving pin RD,

[0037] The 485 communication unit has a first output pin A and a second output pin B, the two pins A and B receive and transmit 485 serial port signals, and the 485 communication unit also has an output pin R for receiving signals, an input pin D of a signal output driver, a control port RE for receiving signals, and a control port DE for outputting signals.

[0038] The conversion circuit includes a buffer U1, a buffer U2 and a NAND gate U3, the input end of the buffer U1 is connected to the output pin R of the 485 communication unit, and the output end is connected to the signal transmitting pin TD of the optical fiber communication unit, the input end of the buffer U2 is connected to the receiving pin RD of the optical fiber communication unit, and the output end is connected to the input pin D of the signal output driver of the 485 communication unit;

[0039] The output end of the NAND gate U3 is connected to the control port RE for receiving signals and the control port DE for outputting signals of the 485 communication unit, one input end of the NAND gate U3 is connected to the output end of the buffer U2, the other input end is connected to the output end of the buffer U2 through a diode D1 and grounded through a capacitor C1, a resistor R1 and the diode D1 are connected in parallel, and the negative electrode of the diode D1 is electrically connected to the negative electrode of the buffer U2.

[0040] When the external optical signal is input through the RX end of the optical fiber communication unit, the internal photodiode of the optical module converts the optical signal into a TTL level electrical signal and outputs it to the buffer U2 through the receiving pin RD, the buffer U2 amplifies the signal and transmits it to the D pin of the RS-485 transceiver, drives the internal circuit to generate RS-485 differential signals and broadcasts them to the bus, when the optical signal is input, the buffer U2 outputs a low level, causing both input ends of the NAND gate U3 to be low. According to the NAND gate logic, U3 outputs a high level to the DE and RE control ends of RS-485, forcing the RS-485 transceiver to enter the transmission mode, and real-time forwarding the electrical signal converted from the optical signal to the 485 bus.

[0041] When there is an electrical signal on the 485 bus, the RS-485 transceiver receives the differential signal through the A / B pin and converts it into a TTL level signal output from the R pin to the buffer U1. The buffer U1 transmits the signal to the TD pin of the optical fiber communication unit after shaping, and drives the TX end of the optical module to emit an optical signal.

[0042] When the optical signal disappears, the buffer U2 outputs a high level, charges the capacitor C1 through the resistor R1, and makes the second input end of the NAND gate U3 slowly rise. During the charging process, the input end of U3 still maintains "one high and one low", and the output maintains a high level. The RS-485 transceiver continuously stays in the sending mode, ensuring that the residual signals on the bus are completely converted. After the charging is completed, both input ends of U3 are high, and the output jumps to low, forcing the RS-485 transceiver to switch to the receiving mode, preparing to respond to the next bus electrical signal. When the optical signal reappears, the diode D1 quickly releases the charge of the capacitor C1, so that the input end of U3 immediately returns to low, realizing instantaneous response of direction switching and avoiding bus conflict.

[0043] The communication conversion module 13 is electrically connected to the 485 bus 12 and is used for converting the 485 bus 12 into an Ethernet interface and communicating with the switch 20. The communication conversion module 13 adopts a model of Moxa NPort 5150 series. The RS-485 interface of the communication conversion module 13 is connected in parallel to the 485 bus 12 and shares the same bus with the photoelectric acquisition unit 11. The RJ45 port of the communication conversion module 13 is connected to the switch 20 through a network cable, realizing network communication.

[0044] In the embodiment, the pre-processing circuit 14 is further arranged between the 485 communication unit and the 485 bus 12. The pre-processing circuit 14 includes resistors R2, R3 and R4. The resistor R2 is connected between the power supply pin and the first output pin of the 485 communication unit. The resistor R3 is connected between the first output pin and the second output pin of the 485 communication unit.

[0045] The resistor R4 is connected between the second output pin and the ground pin of the 485 communication unit. The two ends of the resistor R3 are respectively electrically connected to the 485 bus 12 through the series connection of inductors L1 and L2. The two ends of the resistor R3 are also respectively grounded through capacitors C2 and C3.

[0046] The pre-processing circuit 14 optimizes the communication signal quality of the 485 bus 12 and enhances the anti-interference ability through the synergistic effect of resistors, inductors and capacitors. The resistors R2 and R4 are respectively connected between the power supply pin, the ground pin and the differential output pin of the 485 communication unit, forming a static bias network, ensuring that the A line voltage is higher than the B line when the bus is idle, avoiding logic state disorder caused by level floating. The resistor R3 is connected in parallel between the differential output pins and serves as a terminal matching resistor to eliminate signal reflection, ensuring that the impedance is consistent with the characteristic impedance of the twisted pair line. The inductors L1 and L2 are connected in series between the resistor R3 and the bus, forming a common mode choke coil to suppress the coupling of high-frequency common mode noise. The capacitors C2 and C3 are respectively connected from the bus to the ground, filtering out high-frequency noise and absorbing transient spikes. Together with the inductors, the capacitors form an LC filter network, further reducing signal ringing and edge distortion.

[0047] Further, the pre-processing circuit 14 further comprises diodes D2, D3 and D4, the anodes of the diodes D3 and D4 are connected in parallel and grounded, the cathodes are respectively connected to the inductors L1 and L2 close to the pins of the 485 bus 12, the connection nodes of the inductors L1 and L2 and the bus are further connected to the anodes of the diodes D2, D3 and D4 connected in parallel and grounded, and the cathodes are respectively connected to the inductors L1 and L2 and the interface end of the bus, thereby forming a common-mode voltage clamping network, when the bus generates a negative transient voltage to ground due to electromagnetic interference, the diodes D3 and D4 are rapidly turned on to clamp the voltage of the bus to ground within a safe range, thereby avoiding damage to the internal receiving end of the 485 communication unit due to negative voltage breakdown, and the diode D2 is connected across the A and B lines, when a high voltage difference appears between the A and B lines due to signal conflict or external interference, the diode D2 is a bidirectional TVS diode which limits the differential voltage to a safe value through avalanche breakdown characteristics.

[0048] The embodiment can convert and transmit optical signals and electrical signals through the information acquisition end 10, and can convert the optical signals into electrical signals using the same circuit, thereby directly converting cable communication into optical fiber communication, flexibly switching the optical fiber signals and the 485 signals according to actual needs, avoiding the strict alignment requirement and expensive special distributor in the traditional optical fiber scheme, reducing the complexity of connection by introducing the conversion circuit, making the increase and expansion of nodes more simple, the 485 bus can be connected to multiple information acquisition ends, the multipoint connection capability allows multiple photoelectric acquisition units 11 to work simultaneously, the reliability of the optical fiber communication unit ensures high stability in the transmission process, the high bandwidth characteristics provided by the optical fiber communication unit 11 significantly improve the data transmission efficiency, especially when processing large-scale analog data, the real-time performance of the deduction system is ensured, at the same time, the combination of the multipoint connection capability of the 485 and the high reliability of the optical fiber enhances the flexibility and fault tolerance of the system.
