Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0057] The technical solution of the utility model will be introduced and explained through several embodiments.

[0058] In one embodiment, the utility model provides a multi-interface integrated wiring device, which includes: a box 1, and a switch chip 4 and a main controller 5 integrated in the box 1. Figure 1 , Figure 2 shown.

[0059] The device also includes: a WAN interface 3.

[0060] The device also includes: a plurality of Ethernet interfaces 2.

[0061] Each Ethernet interface 2 is integrated on the box 1 .

[0062] The WAN interface 3 is integrated on the box 1 .

[0063] WAN interface 3 is used to connect to the WAN port of an external 4G router.

[0064] The WAN interface 3 is connected to the WAN port of the switch chip 4 .

[0065] In this embodiment, the switch chip 4 has a routing switching function, which can determine the path of data traffic according to the MAC address of the network device and forward the data to the corresponding destination. This process is achieved by matching and screening through the internal routing table.

[0066] Specifically, the switch chip 4 is connected to each Ethernet interface 2 to provide an exclusive electrical signal path for external devices connected to any two Ethernet interfaces 2 .

[0067] The main controller 5 is connected to the switch chip 4 . The main controller 5 integrates a switch main control board for managing and monitoring the Ethernet interfaces 2 connected to the switch chip 4 .

[0068] In this embodiment, the number of Ethernet interfaces 2 (ie, Ethernet output interfaces) is eight, and all of them are RJ45 Ethernet interfaces.

[0069] This device is used in an equipment box. When in use, the WAN port of the 4G router in the equipment box can be connected to this device through the above-mentioned WAN interface, and the network port of the device connected inside and outside the equipment box can be connected to the Ethernet output interface through a network cable. The communication complies with the Ethernet communication standard. A total of eight RJ45 Ethernet interfaces are provided.

The transmission modes are full-duplex, half-duplex, and full-duplex and half-duplex adaptive.

[0070] Optionally, the device further comprises: a main 485 chip 6. Figure 4 shown.

[0071] The main controller 5 is connected to the main 485 chip.

[0072] The main controller 5 integrates a 485hub main control board, which can control the input and output of data (485 signals). Through the main controller 5, the user can manage and monitor each port to ensure smooth data transmission.

[0073] 485hub main control board, that is, 485HUB main control board, also known as RS485 hub.

[0074] The master 485 chip 6 is connected to a plurality of slave 485 chips 9 and a master 485 signal input interface 7 .

[0075] Each slave 485 chip 9 is connected to an RS485 interface 8. Figure 3 , Figure 4 shown.

[0076] The master 485 chip and the slave 485 chips 9 are integrated in the box 1 .

[0077] The master 485 signal input interface and the RS485 interfaces 8 connected to the slave 485 chips are integrated on the box 1.

[0078] The main 485 signal input interface 7 is used to connect to an external RTU telemetry terminal.

[0079] In this embodiment, both the master 485 chip 6 and the slave 485 chip 9 are RS485 chips. The master 485 signal input interface is an RS485 signal input interface.

[0080] In this embodiment, the number of the RS485 chips is four, and the number of the RS485 interfaces 8 is correspondingly four.

[0081] It can be understood that the main controller 5 in the present invention supports the RS-485 communication standard.

[0082] It can be understood that when in use, the master 485 chip 6 converts the differential signal on the master 485 signal input interface 7 (for connecting to the RTU) into a TTL level, and then distributes it to the slave 485 chips 9 of other branches in a broadcast manner, which are then converted into differential signals by the slave 485 chips 9 and sent to each RS485 interface 8, thereby realizing the 485 protocol communication between the RTU and the controlled devices connected to each RS485 interface 8.

[0083] Optionally, the device further includes: a power input interface 10 and a four-channel DC-DC converter 12. Figure 6 shown.

[0085] The four-channel DC-DC converter 12 is connected to the power input interface 10, and can convert the 18V-36V DC power connected to the power input interface 10 into four 5V / 12V / 15V / 24V / 48V DC power for output.

[0086] The four-channel DC-DC converter 12 has four independent output channels, and each channel can adjust the output voltage separately. In this embodiment, each channel of the four-channel DC-DC converter 12 can convert the connected DC power supply into any one of 5V, 12V, 15V, 24V, and 48V for output. In specific use, technicians in this field can pre-select and set the DC voltage output by each channel of the four-channel DC-DC converter 12 according to actual needs, so that each channel of the four-channel DC-DC converter 12 can convert the DC power supply connected to the four-channel DC-DC converter 12 into the pre-selected DC voltage corresponding to the channel for output. When an external device that requires a different DC voltage is connected, it is only necessary to connect the power interface of the external device to the power output interface that outputs the corresponding voltage, thereby avoiding the need to adjust the solar controller to provide DC power of different voltages to the external device.

[0087] Each of the four output circuits of the four-channel DC-DC converter 12 is connected to a power output interface 13 for outputting the DC power converted by the corresponding circuit. Figure 5 , Figure 6 shown.

[0088] The main controller 5 is connected to the four-channel DC-DC converter 12 and is used to control the working mode of the DC-DC converter and the opening and closing of its four output circuits.

[0089] Each power output interface is integrated on the box body 1.

[0090] The main controller 5 integrates a power control function, which can control the input and output of the power supply. Through the main controller 5, the user can manage and monitor each port to ensure the smooth transmission of the power supply.

[0091] In this embodiment, the power source connected to the power input interface 10 is also used to power the entire multi-interface integrated wiring device. In specific implementation, a manual control switch can be set on the power supply circuit of the entire multi-interface integrated wiring device to control the on and off of the power supply circuit of the entire multi-interface integrated wiring device. When the manual control switch is turned off, the power supply circuit is cut off. When the manual control switch is closed, the power supply circuit is turned on. It can be understood that the manual control switch is integrated on the box 1 for easy operation.

[0093] The console port 11 is integrated on the cabinet 1. The console port is the console interface.

[0094] The console port 11 is connected to the main controller 5 and is used for the outside to set the output voltage of each DC-DC converter of the four-channel DC-DC converter 12 through the console port 11 and the main controller 5 .

[0095] When in use, the power input interface 10 can be connected to the power output end of the solar controller of the external solar power supply system. The power is input by the solar controller (18V-36V DC power supply), and after voltage conversion by the four-channel DC-DC converter 12, it can be converted into four 5V / 12V / 15V / 24V / 48V DC power supplies to power the equipment in the equipment box.

[0096] The main controller 5 is integrated with a DC-DC control module to control the working mode of the four-channel DC-DC converter 12 and the opening and closing of the four-channel corresponding circuits. Specifically, the DC-DC control module of the main controller 5 can be programmed through the above-mentioned Console port 11, and the output voltage of each DC-DC converter of the four-channel DC-DC converter 12 can be controlled by programming to make the output voltage suitable for use by electrical equipment.

[0097] When there is no electrical device at a power output end of the four-channel DC-DC converter 12, the DC-DC control module of the main controller 5 can be programmed through the above-mentioned Console port 11, and the power output end of the four-channel DC-DC converter 12 without electrical device can be turned off through programming control to stop the output of current, thereby effectively reducing energy waste and lowering the operating temperature of the equipment.

[0098] In this embodiment, the WAN interface 3, the main 485 signal input interface 7, the power input interface 10 and the Console port 11 are integrated on the back of the box 1, and the Ethernet interface 2, the RS485 interface 8 and the power output interface 13 are integrated on the front of the box 1.

[0101] Before installing the device, an anti-sticking layer can be set at the bottom of the strong adhesive layer. When in use, the anti-sticking layer is torn off, and the multi-interface integrated wiring device is pasted to the corresponding position through the strong adhesive layer.

[0102] Optionally, the main controller 5 adopts an ARM-IMX6UL processor, the switch chip 4 adopts an RTL8309N-CG chip, the master 485 chip 6 and the slave 485 chip 9 both adopt SP485EN chips, and the model of the four-channel DC-DC converter 12 is LD-35-XX-2.

[0103] It should be noted that the main controller 5, switch chip 4, master 485 chip 6, slave 485 chip 9 and four-channel DC-DC converter 12 involved in the present invention can also adopt other circuit forms or other commonly used models commonly used in the field.
