[0035] A cable reel is a reel that provides the function of winding electric wires and cables. It is widely used in industrial and mining enterprises and construction sites as a power source for imported equipment. However, the inventors have found that existing cable reels only have the function of transmitting power and do not have the function of transmitting data. If data transmission is required on site, it is necessary to lay another data line for transmission, which increases on-site operation costs and reduces operation efficiency.

[0036] In view of the above technical problems, the embodiments of the present disclosure provide a mobile cable tray for transmitting power and network signals, such as Figure 1 As shown, a mobile cable reel for transmitting power and network signals includes: a cable 110, a winding reel, a bracket 120 and a first power carrier module. The cable 110 includes an input end and an output end. The winding reel is configured to wind the cable 110. The winding reel is rotatably disposed on the bracket 120. The first power carrier module is disposed on the bracket 120. The first power carrier module includes a module receiving end, a network output end and a power output end. The receiving end is connected to the output end of the cable 110. The first power carrier module is configured to be able to transmit power through the power output end, and demodulate the composite signal of the cable 110 to output the network signal through the network output end.

[0037] The present disclosure provides a mobile cable reel for transmitting power and network signals, and a first power carrier module is built in the mobile cable reel. The first power carrier module can demodulate the composite signal on the cable line 110 to output the network signal through the network output terminal, and the composite signal of power and network signal can be transmitted through the cable line 110, that is, by combining the cable reel with the first power carrier module, the network data can be transmitted along the cable line 110 over a long distance while the cable line 110 transmits power, thereby achieving the purpose of transmitting network data.

[0038] like Figure 2 As shown, the mobile cable reel for transmitting power and network signals provided by the present disclosure also includes: a second power carrier module 210, the second power carrier module 210 includes a network input terminal 230, a power input terminal and a module output terminal 240, and the power output terminal is configured to be connected to the input terminal of the cable line 110; the second power carrier module 210 is configured to be able to superimpose the network signal input by the network input terminal 230 on the electrical signal input by the power input terminal, so as to output a composite signal of transmitting power and network signals through the module output terminal 240.

[0039] Through the second power carrier module 210, the network signal can be modulated onto the cable line 110, so that the cable reel has the function of network transmission, and the existing cable line 110 is used to solve the network wiring problem.

[0040] Specifically, Figure 3 As shown, the working principle of the power carrier module mainly involves the following steps:

[0041] Signal generation: The second power carrier module 210 first converts the power information into a digital signal, and then converts it into a high-frequency electrical signal through a series of processing, such as filtering. This process requires filtering the power supply to ensure the quality and stability of the signal.

[0042] Signal modulation: The digital signal is converted into an analog signal through the modulator of the first power carrier module, and the frequency of the carrier signal is used to represent the binary data 0 and 1, that is, the frequency shift key modulation technology is used; the modulated signal is processed by a filter, and then amplified by an amplifier and then enters the power line for transmission;

[0043] Signal transmission: The second power carrier module 210 superimposes the high-frequency signal on the low-frequency power line through a coupler to form a composite signal, so that the cable 110 becomes a channel for transmitting power and data at the same time;

[0044] Signal demodulation: After the module receiving end of the first power carrier module receives the composite signal transmitted by the cable 110, it demodulates the composite signal to convert it into a digital signal; the demodulation process generally adopts a coherent demodulation method, that is, the received signal is compared with the local signal, and then the signal is converted into a digital signal after anti-interference through a filter;

[0045] Signal amplification and verification: The first power carrier module amplifies the demodulated signal to a suitable amplitude so that it can be recognized by the subsequent circuit; the amplification process also needs to be filtered to ensure the quality of the signal. At the same time, the module receiving end will verify and correct the received signal to ensure the accuracy and integrity of the data;

[0046] Signal restoration: In the coordinator of the first power carrier module, the network signal is modulated and demodulated from the carrier signal according to the demodulator to realize data communication.

[0047] Specifically, the bracket 120 includes a hollow shaft, and the winding drum is rotatably mounted on the hollow shaft. The winding drum can retract and release the cable 110 by rotating, so as to achieve the purpose of long-distance power transmission. When long-distance power transmission is required, the cable 110 is pulled, and the winding drum rotates on the hollow shaft to release the cable 110 wound on the winding drum; when the cable 110 is retracted, the cable 110 is wound on the winding drum by rotating the winding drum, so as to achieve the retraction of the cable 110.

[0048] A handle may be provided on the winding drum, so that the winding drum can be driven to rotate by moving the handle, so as to improve the winding efficiency of the cable 110 on the winding drum when it is retracted.

[0049] Among them, the first power carrier module is arranged in the cavity of the hollow shaft, that is, the first power carrier module is integrated and built into the bracket 120, so that the cable reel is basically consistent with the appearance of a conventional cable reel in appearance, avoiding excessive changes in the appearance of the cable reel due to the installation of the first power carrier module, thereby ensuring that the cable reel occupies a relatively small space and is easy to use.

[0050] Of course, the central axis of the bracket 120 on which the winding reel is mounted may also be a solid axis, and the first power carrier module may be disposed on other areas of the bracket 120 .

[0051] like Figure 1As shown, a connection panel 121 is provided on the bracket 120, and a power socket 130 and a network output interface 140 are provided on the connection panel 121. The power socket 130 is connected to the power output terminal, and the network output interface 140 is connected to the network output terminal. Through the power socket 130, the power transmitted on the cable 110 can be supplied to the external power-consuming device; through the network output interface 140, the network signal modulated and demodulated from the carrier signal on the cable 110 by the first power carrier module is output. The power socket 130 and the network output interface 140 are located on the same connection panel 121, which is convenient for connecting the power-consuming device and the network signal receiving device, thereby improving the convenience of use. Of course, the power socket 130 and the network output interface 140 can also be located on different installation panels, and the present disclosure does not limit this.

[0052] The surface of the connection panel 121 on which the power socket 130 and the network output interface 140 are provided is perpendicular to the rotation axis of the cable winding reel, that is, the connection panel 121 can be located on the side of the cable winding reel, which is convenient for the installation of the connection panel 121. Of course, the surface of the connection panel 121 on which the power socket 130 and the network output interface 140 are provided is an acute angle or an obtuse angle with the rotation axis of the cable winding reel, and the present disclosure does not limit this.

[0053] like Figure 1 As shown, a cable reel switch 150 is also provided on the connection panel 121. By providing the cable reel switch 150, the power supply of the cable line 110 can be cut off or turned on, thereby realizing the control of the power supply of the cable reel, so as to control the power supply to the electrical equipment.

[0054] like Figure 1 As shown, a fuse holder 160 is also provided on the connection panel 121. By providing the fuse holder 160 and setting the fuse in the fuse holder 160, overload limitation on the cable 110 is achieved to avoid excessive current on the cable 110, and at the same time, it is convenient for replacement and maintenance of the fuse.

[0055] In addition, an indicator light may be provided on the connection panel 121, and when the cable 110 is powered on, the indicator light comes on; or, when the cable reel switch 150 is in an on state or a off state, different indicator lights come on, or the same indicator light emits different colors.

[0056] like Figure 1 As shown, a first plug 111 is provided on the input end of the cable 110. By providing the first plug 111, it is plugged into the module output end 240 on the second power carrier module 210, which facilitates connection and improves convenience of use.

[0057] like Figure 2As shown, a second plug 220 is provided on the power input end of the second power carrier module 210. By connecting to the mains through the second plug 220, the second power carrier module 210 can be plugged into the mains socket, which is convenient for connection and improves convenience of use.

[0058] like Figure 2 As shown, the network input terminal 230 and the module output terminal 240 are located on the same side of the second power carrier module 210. By making the network input terminal 230 and the module output terminal 240 located on the same side of the second power carrier module 210, it is convenient to connect the first plug 111 with the network output terminal. Of course, the network input terminal 230 and the module output terminal 240 can also be located on different sides of the second power carrier module 210, and the present disclosure does not limit this.

[0059] like Figure 2 As shown, the power input terminal and the module output terminal 240 are located on opposite sides of the second power carrier module 210. By making the power input terminal and the module output terminal 240 located on opposite sides of the second power carrier module 210, it is convenient for the module output terminal 240 of the second power carrier module 210 to be plugged into the first plug 111 after the second plug 220 is connected to the mains. Of course, the power input terminal and the module output terminal 240 are located on non-opposite sides of the second power carrier module 210, and the present disclosure does not limit this.
