Description

Technical Field

[0001] The present application relates to the field of electrical engineering technology, and in particular to a two-wire ultra-high-speed PLC carrier module. Background Art

[0002] As the pixels of network cameras are getting higher and higher, the bandwidth occupied is getting larger and larger; with the continuous increase of network equipment, the bandwidth of existing 100M products can no longer meet the demand, and a product with a larger bandwidth is needed. The communication lines on site are generally two-core wires, requiring product signal transmission to adopt only two-wire system, and the traditional PLC (Power Line Carrier communication) carrier module is difficult to effectively use communication technology, such as orthogonal frequency division multiplexing technology, when facing the large flow and high bandwidth data transmission requirements of the two-core wire. The reason is that the traditional PLC carrier module cannot efficiently use the network transformer. More specifically, the traditional carrier module cannot achieve high-energy signal output based on inductance under the premise of constant volume. For this reason, it is necessary to propose a two-wire ultra-high-speed PLC carrier module in view of the fact that the traditional carrier module cannot meet the large flow and high bandwidth data transmission requirements of the two-core wire. Utility Model Content

[0003] It is necessary to propose a two-wire ultra-high-speed PLC carrier module as the traditional carrier module cannot meet the large flow and high bandwidth data transmission requirements of the dual-core line.

[0004] The present application relates to a two-wire ultra-high-speed PLC carrier module, including a receiver and a transmitter, wherein the receiver and the transmitter have the same structure, and the receiver includes:

[0005] Power module;

[0006] A storage module, electrically connected to the power module;

[0007] A signal processing module, which is communicatively connected to the storage module, and the signal processing module is electrically connected to the power supply module;

[0008] The external communication module is communicatively connected with the signal processing module, and the signal processing module is electrically connected with the power supply module; the power supply voltage of the external communication module is greater than or equal to 3.3V.

[0009] The present application relates to a two-wire ultra-high-speed PLC carrier module, and the power supply of the two-wire ultra-high-speed PLC carrier module is realized by a power module. Since the present application needs to be applied to a relatively harsh natural environment, it is necessary to perform lightning protection, surge protection and power reverse plug-in protection operations. The storage module, as an information storage device of the signal processing module, provides a storage carrier for input signals and output signals. Since the power module, the storage module and the signal processing module are in the two-wire ultra-high power module, and the conduction circuits of the storage module and the signal processing module are in the two-wire ultra-high-speed PLC carrier module, the power module can provide a 3.3V power supply voltage. This is because the 3.3V power supply voltage can meet the needs of signal transmission. The communication distance of the external communication module is long, and it is necessary to suppress large clutter interference, so the external communication module further increases the non-localization of high and low level signals, and realizes the large flow and high bandwidth data transmission requirements of the dual-core wire.

[0020] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] The present application provides a two-wire ultra-high-speed PLC carrier module.

[0023] The storage module 200 is electrically connected to the power supply 423 module 100 .

[0024] The signal processing module 300 is in communication connection with the storage module 200 , and the signal processing module 300 is in electrical connection with the power supply 423 module 100 .

[0025] The external communication module 400 is communicatively connected to the signal processing module 300 , and the signal processing module 300 is electrically connected to the power supply 423 module 100 .

[0026] Specifically, the power supply 423 of the two-wire ultra-high-speed PLC carrier module is realized by the power supply 423 module 100. Since the present application needs to be applied to a relatively harsh natural environment, it is necessary to perform lightning protection, surge protection and anti-power supply 423 reverse insertion operations. The storage module 200, as an information storage device of the signal processing module 300, provides a storage carrier for input signals and output signals. Since the power supply 423 module 100, the storage module 200 and the signal processing module 300 are located inside the two-wire ultra-high-speed PLC carrier module, the power supply 423 module 100 can provide a 3.3V supply voltage. This is because the 3.3V power supply 423 voltage can meet the needs of signal transmission.

[0027] The present application relates to a two-wire ultra-high-speed PLC carrier module. The communication distance of the external communication module 400 is relatively long, and it is necessary to suppress large clutter interference, so it is necessary to further increase the non-localization of high and low level signals to meet the large flow and high bandwidth data transmission requirements of the dual-core wire.

[0028] like Figure 2As shown, in one embodiment of the present application, the two-wire ultra-high-speed PLC carrier module includes a receiver a and a transmitter b. The receiver a and the transmitter b have the same structure. The receiver a includes a power supply 423 module 100, a storage module 200, a signal processing module 300 and an external communication module 400.

[0029] Specifically, the network transmission module of the present application must be used in pairs, and each unit module includes a receiver a and a transmitter b. Receiver a and transmitter b are powered by a DC 12V power supply 423 respectively. Receiver a and transmitter b have the same structure. Receiver a includes a power supply 423 module 100, a storage module 200, a signal processing module 300 and an external communication module 400.

[0030] This embodiment involves a receiver a and a transmitter b. A two-wire ultra-high-speed PLC carrier module composed of a receiver a and a transmitter b can meet the data transmission requirements of large flow and high bandwidth of a dual-core wire by increasing the non-localization of high and low level signals. More specifically, the two-wire system can be a twisted pair.

[0032] Specifically, the first layer of protection of the receiver a or the transmitter b can be achieved through the lightning protection module 110 (generally inactive) and the overcurrent protection module 120. Furthermore, the lightning protection module 110 and the overcurrent protection module 120 actually protect the components of the power supply 423 module 100 from being safe and intact at the strong current level.

[0033] This embodiment involves the hardware layer security protection of the power supply 423 module 100, which ensures the device security of the entire circuit device at the power supply 423 source level.

The anti-protection circuit 150 is electrically connected to the power supply 423 chip circuit 160.

[0035] Specifically, after the rectifier circuit 130, the power supply 423 filter circuit 140, the anti-protection circuit 150 and the power supply 423 chip circuit 160 are powered, the power supply 423 chip outputs voltage to power each chip. When the Flash chip works, the PLC system runs according to the set program. The device will send a handshake signal. After the other device receives the signal, it will send a signal notification. The two devices begin to establish a communication connection. After the connection is successful, network data transmission can be carried out.

[0036] This embodiment relates to a power supply 423 module 100. The power supply 423 module 100 can realize the communication connection between the receiver a and the transmitter b. After the connection is successful, the network data transmission process can be performed.

The main chip 310 is electrically connected to the power supply 423 chip circuit 160.

[0038] Specifically, the main chip 310 and the operational amplifier 320 can enable the PLC system to run according to the set program. The device will send a handshake signal. After the other device receives the signal, it will send a signal notification. The two devices begin to establish a communication connection. After the connection is successful, network data transmission can be carried out.

[0039] like Figure 3 As shown, in one embodiment of the present application, the signal processing module 300 further includes a first-level EMC protector 330, a second-level EMC protector 340, a third-level EMC protector 350 and a coupler 360.

[0040] The storage module 200 is electrically connected to the power supply 423 chip circuit 160. The storage module 200 is communicatively connected to the main chip 310.

[0041] The external communication module 400 includes a switch chip 410, a signal transformer 420 and a communication connector 430. The switch chip 410 is connected to the main chip 310 for communication. The switch chip 410 is electrically connected to the power supply 423 chip circuit 160. The switch chip 410 is connected to the signal transformer 420 for communication. The signal transformer 420 is connected to the communication connector 430 for communication.

[0042] Specifically, the network signal of transmitter b passes through the RJ45 network port, is electrically isolated by the gigabit network transformer 424, and then enters the gigabit switch chip 410, and is transmitted to the main chip 310. After the data is processed, it is amplified by the operational amplifier chip, and transmitted to the receiving end through two core wires. The received signal is restored by the operational amplifier chip, and the analog signal is demodulated into a digital signal by the main chip 310, and then processed by the main chip 310 and transmitted to the gigabit network port chip. After passing through the gigabit network transformer 424, the RJ45 network port outputs the network data.
