[0042] The core of the present application is to provide a monitoring device management apparatus, which can provide two kinds of voltages for a monitoring device to supply power for the monitoring device, and also utilizes the network port voltage of Ethernet to save power.

[0043] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described below in connection with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0044] Please refer to Figure 1 , Figure 1 A structural schematic diagram of a monitoring device management apparatus provided by the present application is shown in the figure, which comprises:

[0045] The first input end is connected with a power supply, the first output end is connected with a first power supply end of the monitoring device through a power supply channel 1, and the first power supply channel 1 is used to supply power for the monitoring device based on the first voltage output by the power supply and set by a user;

[0046] A first network connection module 2 provided between the Ethernet and the monitoring device, for establishing network communication between the Ethernet and the monitoring device when the power supply supplies power to the monitoring device through the power supply channel 1;

[0047] The power supply network integrated channel 3 is set between the Ethernet and the second power supply end of the monitoring device, and is used to establish network communication between the Ethernet and the monitoring device based on the user's settings, and convert the Ethernet port voltage into a second voltage to power the monitoring device. The first voltage is not equal to the second voltage.

[0048] In this embodiment, the applicant takes into account that in the prior art, there is usually only one power supply method for monitoring equipment, such as only 12V power supply, but some monitoring equipment requires different power supply voltages, and the monitoring equipment management device in the prior art cannot meet the power requirements of the monitoring equipment.

[0049] In order to solve the above technical problems, a power supply channel 1 and a first network connection module 2 connected to the power supply are set in this application. The power supply channel 1 can power the monitoring device with the first voltage output by the power supply. The first network connection module 2 can establish network communication between the monitoring device and the Ethernet, that is, connect the monitoring device to the network. It should be noted that if the monitoring device is powered by the power supply channel 1, the first network connection module 2 is required to connect the monitoring device to the network.

[0050] If the monitoring device requires a second voltage for power supply, the power supply network integrated channel 3 can convert the Ethernet port voltage into the second voltage, while connecting the monitoring device to the network, saving energy and ensuring power supply for the monitoring device.

[0051] It should be noted that the user can, according to needs, only control the power supply channel 1 to power the monitoring equipment and the first network connection module 2 to connect the monitoring equipment to the network, or only control the power supply network integrated channel 3 to power the monitoring equipment and connect the monitoring equipment to the network. In addition, according to needs, both power supply modes can be controlled to work simultaneously, and this application does not limit this.

[0052] Among them, the power supply network integrated channel 3 is connected to POE (Power Over Ethernet). POE refers to a technology that can provide DC power to some IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras, etc.) while transmitting data for such devices without making any changes to the existing Ethernet Cat.5 wiring infrastructure.

[0053] In summary, two voltages can be provided for the monitoring equipment to power the monitoring equipment, and the Ethernet port voltage is also utilized to save electricity.

[0054] Based on the above embodiment:

[0055] As a preferred embodiment, the power supply network integrated channel 3 includes:

[0056] The input end is connected to the input interface of the Ethernet, and is used to receive the Ethernet network and the Ethernet port voltage based on the user's settings;

[0057] A second network connection module provided between the input interface and the monitoring device, for establishing network communication between the Ethernet and the monitoring device;

[0058] A voltage conversion circuit having an input end connected to the input interface, and configured to convert an Ethernet network port voltage into a first voltage;

[0059] The DC / DC conversion circuit has an input end connected to the output end of the voltage conversion circuit and an output end connected to the second power supply end of the monitoring device, and is used to convert the first voltage output by the voltage conversion circuit into a second voltage to power the monitoring device.

[0060] The integrated power supply network channel 3 in this embodiment includes an input interface, a second network connection module, a voltage conversion circuit, and a DC / DC conversion circuit. The input interface is connected to the Ethernet network and can receive the Ethernet network port voltage and network, so that the second network connection module can establish network communication between the Ethernet and the monitoring device. In addition, since the Ethernet network port voltage is approximately 48V, if the second voltage required by the monitoring device is less than 48V, the voltage conversion circuit and the DC / DC conversion circuit are required to convert the Ethernet network port voltage to power the monitoring device. Furthermore, POE has two power supply modes: one is to output both the network and voltage, and the other is to output the network and voltage separately.

[0061] The input interface in this embodiment can be but not limited to RJ45 (Registered Jack 45), which is connected to POE. Figure 2 , Figure 2 This is a structural diagram of an input interface provided by the present invention. Figure 2 The input interface P1, that is, the NC1 and NC2 ends of the RJ45 are connected to the PSE1+ of the POE, and the NC3 and NC4 are connected to the PSE1- of the POE to receive the Ethernet voltage. The RX+ is connected to the RD+ of the POE, the RX- is connected to the RD- of the POE, the TX+ is connected to the TD+ of the POE, and the TX- is connected to the TD- of the POE to receive the Ethernet network signal.

[0062] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of a network connection module provided by the present invention. It should be noted that both the first network connection module 2 and the second network connection module can beFigure 3 The first network connection module 2 and the second network connection module can be multiplexed. Figure 3 The RX+, RX-, TX+ and TX- ports of the network connection module T1 in the structure are respectively connected with the homonymic ports of the RJ45 in the structure Figure 2 The RJ45 in the structure is connected with the homonymic ports to receive the network signals of RD+, RD-, TD+ and TD-, and convert the signals into the format of RX+, RX-, TX+ and TX- and send to the monitoring device to establish the network connection between the monitoring device and the Ethernet.

[0063] In addition, Figure 3 The CTTX of the network connection module T1 is connected with the PSE2+ of the POE, and the CTRX is connected with the PSE2- of the POE to receive the voltage of the Ethernet, but the connection mode of the PSE2+ of the POE and the PSE2- of the POE is not used in the application, thus the CTTX and the CTRX are grounded through the resistors C1 and C2, the resistors R1 and R2 and the capacitor C5, the CTTD and the CTRD of the network connection module T1 are grounded through the capacitors C3 and C4, and the ground of C5 and C3, C4 is different, to realize the signal level coupling, isolate the outside world, enhance the anti-interference ability, and add the protection effect (such as lightning strike) to the network connection module T1.

[0064] It should be noted that a voltage conversion module is also arranged between the input interface and the voltage conversion circuit, please refer to Figure 4 , Figure 4 The structure diagram of a voltage conversion module provided by the application, Figure 4 The rectifiers U1 and U2 rectify the alternating current PSE1+ and PSE1- and PSE2+ and PSE2- output by the POE to output the 48V direct current, i.e. the direct current PSE+ and PSE-. Based on this, no matter which power supply mode of the POE is used, it can be rectified to the fixed 48V direct current. The model of U1 and U2 can be but is not limited to MB110S.

[0065] It should be noted that the network and voltage of the POE are jointly output as PSE1+ and PSE1- and the network signal is jointly output, and the network and voltage are respectively output as PSE2+ and PSE2- and the network signal is respectively output, but no matter which mode is used, the network signal needs to be converted through the network connection module in the structure. Figure 3

[0066] As a preferred embodiment, the second input end of the power supply channel 1 is connected with the voltage conversion circuit, and is also used to supply power to the monitoring device based on the first voltage output by the voltage conversion circuit according to the setting of the user.

[0067] ​The power supply channel 1 in this embodiment can not only power the monitoring device through the first voltage output by the power supply, but is also connected to the voltage conversion circuit, so that the monitoring device is directly powered by the first voltage output by the voltage conversion circuit, saving energy loss of the power supply and reducing costs.

[0068] The first voltage may be, but is not limited to, 12V, that is, the power supply channel 1 can also transmit the 12V DC power output by the voltage conversion circuit to the monitoring device to provide 12V DC power for the monitoring device.

[0069] As a preferred embodiment, the second output end of the power supply channel 1 is connected to the input end of the DC / DC conversion circuit, and the DC / DC conversion circuit is also used to convert the first voltage output by the power supply channel 1 into a second voltage based on the user's settings to power the monitoring device.

[0070] The DC / DC conversion circuit in this embodiment can also convert the first voltage output by the power supply channel 1 into a second voltage to power the monitoring device. Based on this, the two power supply channels 1 in this application are connected to each other, saving energy under certain conditions.

[0071] Among them, the first voltage can be but is not limited to 12V, and the second voltage can be but is not limited to 5V, that is, the DC / DC conversion circuit can also convert the 12V DC power output by the power supply channel 1 into 5V DC power and transmit it to the monitoring device to provide 5V DC power for the monitoring device.

[0072] As a preferred embodiment, the present invention further comprises:

[0074] A second filtering module provided at the output end of the DC / DC conversion circuit;

[0075] The number of capacitors in the first filter module and the second filter module are equal, and the structures are symmetrical.

[0076] The first voltage output by the voltage conversion circuit or power supply in this application is first passed through the first filter module before being input into the DC / DC conversion circuit. After the DC / DC conversion circuit performs voltage conversion, it is output through the second filter module. This can reduce the harmonics of the input and output voltages and ensure the normal power supply to the monitoring equipment. In addition, the number of capacitors in the first filter module and the second filter module is equal and the structure is symmetrical, which can greatly improve the power supply quality and make the voltage smoother. Please refer to Figure 5 , Figure 5 This is a structural schematic diagram of a DC / DC conversion circuit and accessories connected thereto provided by the present invention. Figure 5The DC / DC converter circuit's input terminal VIN is connected to a first filter module consisting of capacitors C12, C13, C14, C15, and C19. The output terminal SW is connected to a second filter module consisting of capacitors C7, C8, C9, C10, and C11. The DC / DC converter circuit converts the input voltage (12V) to a 5V / 2A DC output, also known as the second voltage. The SW pin of the DC / DC converter circuit is connected to inductor L1. The feedback signal from the DC / DC converter circuit passes from the rear end of inductor L1 through resistor R4 to the FB pin of the DC / DC converter circuit. Resistors R4 and R6 form an output resistor divider, satisfying the equation: R6 = R4 * (VOUT / 0.8-1). VOUT is the output voltage of the DC / DC converter circuit, also known as the second voltage. The DC / DC converter circuit can be, but is not limited to, a chip such as AP64501 or MP2314GJ.

[0077] Please refer to Figure 6 and Figure 7 , Figure 6 The power ripple diagram provided by the present invention only has the first filter module. Figure 7 The power ripple diagram of the symmetrical filter modules provided by the present invention shows that the output ripple can be reduced by providing a symmetrical first filter module and a second filter module at the input and output ends of the DC / DC conversion circuit.

[0081] The voltage conversion circuit in this embodiment includes a step-down chip and a transformer, wherein the step-down chip can adjust its own output voltage according to the feedback signal output by the transformer, so that the voltage output by the transformer is finally stabilized at a second voltage. This closed-loop control can ensure normal power supply to the monitoring equipment.

[0083] The voltage conversion circuit in the application can adopt a POE conversion circuit: its working principle is to convert the 48V direct current voltage output by the voltage conversion module into a 12V direct current voltage and output to the direct current / direct current conversion circuit. The VDD pin of the step-down chip in the POE conversion circuit is the input end of the step-down chip, the FB1 pin is the feedback end of the step-down chip, the VSS pin is the ground end of the step-down chip, and the SW pin is the output end of the step-down chip.

[0084] Further, the 48V direct current passes through the transient voltage suppressor D5 and the filter capacitor C81 to the VDD pin of the step-down chip. The SW pin of the chip passes through the diode D2 and the resistor R3 to the transformer, and the capacitor C82 is the filter capacitor of the output end of the step-down chip. The feedback signal passes through the diode D3 and the resistor R7 to the FB1 pin of the step-down chip. Finally, the voltage output by the step-down chip passes through the transformation of the transformer, flows through the rectifier diode D4, and is filtered through the capacitors C83 and C84, and outputs 12V / 1A, i.e., the first voltage.

[0085] In this POE conversion circuit, the step-down chip can specifically include but is not limited to an MPS (Monolithic Power Systems) power chip, such as a chip with a model number MP8007 or the like.
