[0047] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] In the following, the terms "first" and "second" are used for descriptive purposes only and shall not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present utility model, unless otherwise specified, "multiple" means two or more.

[0049] Conventional communication power supplies are AC mains input, converted into DC power by a rectifier unit, and then provided to DC devices. This communication power supply can only operate in areas with stable mains power. For many remote areas, due to long power supply lines and large line losses during the power supply process, the mains input will be unstable or unable to access the mains, so it cannot provide the required DC power for DC devices.

[0050] Based on the above problems, the present utility model provides a communication power supply, such as Figure 1 As shown, it is a structural diagram of a communication power supply provided by an embodiment of the utility model, and the communication power supply comprises: an embedded plug-in frame and an AC unit 101, a rectifier unit 102, a photovoltaic unit 103 and a DC distribution unit 104 fixedly arranged in the embedded plug-in frame;

[0051] The input end of the AC unit 101 is electrically connected to the mains input, and the output end of the AC unit 101 is electrically connected to the input end of the rectifier unit 102;

[0052] The output end of the rectifier unit 102 is electrically connected to the output end of the photovoltaic unit 103 and the input end of the DC power distribution unit 104;

[0053] The output end of the DC power distribution unit 104 serves as a DC output end of the communication power supply.

[0054] In the embodiment of the utility model, the input end of the AC unit 101 is electrically connected to the mains input, and the output end of the AC unit 101 is electrically connected to the input end of the rectifier unit 102; the output end of the rectifier unit 102 is electrically connected to the output end of the photovoltaic unit 103 and the input end of the DC distribution unit 104; the output end of the DC distribution unit 104 serves as the DC output end of the communication power supply. The AC power output by the AC unit is converted into DC power by the rectifier unit, and DC power is provided by the photovoltaic unit. Since the AC unit and the photovoltaic unit can complement each other online, DC power can be stably supplied to the DC device when the mains input is unstable.

[0055] In a specific embodiment, the AC unit 101 can convert the AC power input from the mains into DC power through the rectifier unit 102 and input it into the DC distribution unit 104; the photovoltaic unit 103 can input DC power into the DC distribution unit 104; the DC distribution unit 104 can be electrically connected to the DC device. Since the AC unit 101 and the photovoltaic unit 103 complement each other online to provide DC power to the DC distribution unit 104, the DC distribution unit 104 can provide stable DC power to the DC device.

[0056] In a feasible implementation, taking unstable AC input as an example, if the DC device requires a stable 48V DC power, since the AC power input by the AC unit 101 is unstable, the DC power input to the DC distribution unit 104 through the rectifier unit 102 cannot be stabilized to 48V, and there is an abnormal situation that the voltage is less than the minimum voltage. The photovoltaic unit 103 can input the DC power generated by the photovoltaic unit 103 to the DC distribution unit 104, so that the DC power generated by the photovoltaic unit 103 can complement the DC power converted by the rectifier unit 102, so that the DC distribution unit outputs a stable 48V DC power to meet the needs of the DC device.

[0057] In another feasible implementation, taking the inability to access the mains input as an example, if the DC device requires a stable 10V DC power, since the mains input cannot be accessed, the DC device cannot be provided with DC power through the mains input. However, the DC power generated by the photovoltaic unit 103 can be input into the DC distribution unit 104 through the photovoltaic unit 103, so that the DC distribution unit outputs a stable 10V DC power to meet the needs of the DC device.

[0058] The photovoltaic unit in the utility model can be a solar panel or other new energy equipment.

[0059] In the embodiment of the present utility model, Figure 2 As shown, it is a structural diagram of another communication power supply provided by an embodiment of the utility model, which also includes an inverter unit 201 and an AC power distribution unit 202 fixedly arranged in the embedded plug-in frame;

[0060] The input end of the inverter unit 201 is electrically connected to the output end of the photovoltaic unit 103, and the output end of the inverter unit 201 is electrically connected to the input end of the AC power distribution unit 202;

[0061] The output end of the AC power distribution unit 202 serves as the AC output end of the communication power supply.

[0062] The output end of the AC unit 101 may also be electrically connected to the input end of the AC power distribution unit 202 .

[0063] In a specific embodiment, the communication power supply provided by the embodiment of the utility model can also power AC equipment. When the AC power input is unstable, the photovoltaic unit 103 can convert DC power into AC power through the inverter unit 201 and output it to the AC distribution unit 202 to provide AC power for the AC equipment.

[0064] It should be noted that if Figure 3 As shown, it is a structural diagram of another communication power supply provided by an embodiment of the utility model, and also includes a monitoring unit 301 fixedly arranged in the embedded plug-in frame;

[0065] The monitoring unit 301 is respectively connected to the communication end of the AC unit 101 , the communication end of the rectifier unit 102 , the communication end of the photovoltaic unit 103 , the communication end of the DC distribution unit 104 , the communication end of the inverter unit 201 , and the communication end of the AC distribution unit 202 .

[0066] In a feasible implementation, the monitoring unit 301 can realize that the photovoltaic unit 103 preferentially provides direct current to the direct current device by controlling the working conditions of the AC unit 101 and the photovoltaic unit 103. For example, taking the case where the AC power input is stable and the AC unit 101 can provide stable direct current through the rectifier unit 102, if the monitoring unit 301 controls the AC unit 101 not to work, controls the photovoltaic unit 103 to work, and controls the direct current distribution unit 104 to work, the photovoltaic unit 103 can preferentially provide the required direct current to the direct current device, and green energy can be fully utilized.

[0067] In another feasible implementation, the monitoring unit 301 can realize that the inverter unit 201 preferentially provides AC power to the AC device by controlling the working state of the inverter unit 201. For example, taking the case where the mains input is unstable and the AC power output by the AC unit 101 is unstable, if the monitoring unit 301 controls the inverter unit 201 to work, the photovoltaic unit 103 to work, the AC unit 101 not to work, and the AC distribution unit 104 to work, the inverter unit 201 can preferentially provide the AC power required by the AC device.

[0076] The environment management unit 501 can monitor the working environment of the communication power supply through the monitoring unit 301 and adjust the working environment in time so that the communication power supply can work stably. For example, taking the working temperature of the communication power supply as 0 to 40 degrees, in a feasible implementation, if the temperature reaches 60 degrees when the communication power supply is working, the temperature of the communication power supply is too high at this time, and the environment management unit 501 can reduce the temperature of the working environment of the communication power supply to make the temperature reach a temperature range suitable for the communication power supply to work. In another feasible implementation, if the temperature reaches -20 degrees when the communication power supply is working, the temperature of the communication power supply is too low at this time, and the environment management unit 501 can increase the temperature of the working environment of the communication power supply to make the temperature reach a temperature range suitable for the communication power supply to work.

[0077] In addition, the monitoring unit 301 may further include multiple monitoring sub-units, and the connection method of the multiple monitoring sub-units includes one or more of the following:

[0085] Among them, the first monitoring subunit, the second monitoring subunit, the third monitoring subunit, the fourth monitoring subunit, the fifth monitoring subunit, the sixth monitoring subunit and the seventh monitoring subunit are communicatively connected with each other.
