[0034] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. 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 implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0035] Method Example:

[0036] Figure 1 For a structural diagram of the intelligent switching remote power supply central office device provided in the embodiment of the present application, please refer to Figure 1 The intelligent switching remote power supply central office device provided in this embodiment may specifically include: an input module 1, a basic power module 2, a redundant power module 3, a monitoring module 4, a control module 5, a switching module 6 and an output module 7.

[0037] Specifically, the input end of the input module 1 is connected to an external power supply line such as a 380V AC power supply through a transmission line, and the output end is connected to the basic power module 2 and the redundant power module 3 respectively, and the basic power module 2 and the redundant power module 3 are connected in parallel.

[0038] The basic power supply module 2 and the redundant power supply module 3 are both connected to the input end of the output module 7 through the switching module 6, and the output end of the output module 7 is connected to the external electrical equipment; in this way, the basic power supply module 2 and the redundant power supply module 3 can supply power to the external electrical equipment through the switching module 6 and the output module 7 under the control of the control module 5.

[0039] The first end of the monitoring module 4 is connected to the output module 7 , and the second end of the monitoring module 4 is connected to the input end of the control module 5 ; the monitoring module is used to detect the current and voltage information in the output module, and transmit the detected current and voltage information to the control module 5 .

[0040] In practical applications, the monitoring module 4 can be set at the output end of the output module 7 to detect the current and voltage information of the external power supply of the entire intelligent switching remote power supply local end device, so as to timely find out whether the power supply is abnormal.

[0041] The output end of the control module 5 is connected to the switching module 6. The control module 5 is used to generate a first control signal based on the current and voltage information. The first control signal is used to control the basic power module 2 or the redundant power module 3 to supply power to the outside through the switching module 6.

[0042] It should be noted that the intelligent switching remote power supply terminal device provided in the present application, under normal circumstances, defaults to powering external electrical equipment through the basic power supply module 2; when the monitoring module 4 and the control module 5 detect and determine that the external power supply of the intelligent switching remote power supply terminal device is abnormal, such as when the current and voltage information detected in real time is different from the pre-stored information, the control module 5 generates a first control signal to control the switching module 6 to switch, and convert the power supply module for external power supply from the basic power supply module to the redundant power supply module, thereby ensuring that the external power supply of the intelligent switching remote power supply terminal device is normal and stable.

[0043] The intelligent switching remote power supply terminal device provided in the present application includes an input module 1, a basic power module 2, a redundant power module 3, a monitoring module 4, a control module 5, a switching module 6 and an input module 7; the basic power module 2 and the redundant power module 3 are connected in parallel, the monitoring module 4 monitors the current and voltage signals output by the equipment, and the control module 5 controls the switching module 6 to supply power to the basic power module 2 or the redundant power module 3 based on the detected current and voltage signals. In this way, when a failure of the basic power module 2 is detected, power can be quickly supplied through the redundant power module 3 to avoid power outages, thereby improving the stability of power supply to the remote power supply terminal device.

[0044] Furthermore, if Figure 2 As shown, in some embodiments of the present application, the intelligent switching remote power supply central office device may further include a communication module 8.

[0045] Specifically, the communication module 8 is connected to the input end of the control module 5; the control module 5 is also used to generate a second control signal based on the communication signal sent by the communication module 8, and the second control signal is used to control the basic power supply module 2 and the redundant power supply module 3 to supply power to the outside at the same time through the switching module 6.

[0046] In practical applications, outside the intelligent switching remote power supply local end device, the communication module 8 can be connected to an external control end such as a host computer through a communication cable or wirelessly.

[0047] In some embodiments of the present application, the switching module 6 may include multiple switch modules, for example, may include a first switch module and a second switch module.

[0048] Specifically, the basic power supply module 2 can be connected to the input end of the output module 7 through the first switch module, and the redundant power supply module 3 can be connected to the input end of the output module through the second switch module; and the first switch module and the second switch module are also connected to the input end of the control module 5.

[0049] In actual applications, the control module 5 can control the first switch module to be turned on and the second switch module to be disconnected by generating a first control signal, so that the basic power supply module 2 can supply power to the outside alone; or control the second switch module to be turned on and the first switch module to be disconnected, so that the redundant power supply module 2 can supply power to the outside alone; and can also control the first switch module and the second switch module to be turned on by generating a second control signal, so that the basic power supply module 2 and the redundant power supply module 3 can supply power to the outside at the same time.

[0050] In some embodiments of the present application, the switch module (including the first switch module and the second switch module) may include a transistor, a relay chip, and some basic circuit components to implement the above functions. Figure 3 As shown:

[0051] The first switch module may specifically include a first transistor Q1 and a first relay chip (e.g., Figure 3 BC98-Z100 chip shown), one end of transistor Q1 (such as Figure 3 The first end of R3 in the middle) is connected to the output end of the control module 5, and the input end of the first relay chip ( Figure 3 J2 in the base power module 2, the output terminal of the first relay chip ( Figure 3 J1 in the figure is connected to the input end of the output module 7. Thus, in practical applications, the control module 5 can control the state of Q1 based on the control signal to turn on or off the first relay chip connected to Q1, thereby controlling whether the basic power module 2 supplies power to the outside.

[0052] Similarly, the second switch module may specifically include a second transistor and a second relay chip (which may also be Figure 3 The BC98-Z100 chip shown in FIG. 1 is used for the control module 5, one end of the second transistor is connected to the output end of the control module 5, the input end of the second relay chip is connected to the redundant power module 3, and the output end of the second relay chip is connected to the input end of the output module 7. In this way, in practical applications, the control module 5 can control the state of the second transistor based on the control signal to turn on or off the second relay chip connected to the second transistor, thereby controlling whether the redundant power module 3 supplies power to the outside.

[0053] It should be noted that in practical applications, Figure 2 As shown, because the input of the entire device can be 380V AC, and the output of the entire device is DC, in the intelligent switching remote power supply terminal device provided by the present application, the input module 1 can be a terminal, interface or line including three phases, and the output module 7 can be a terminal, interface or line including positive and negative poles, so Figure 2 The input module 1 and output module 3 are not marked in detail. The specific connection of the corresponding three-phase or positive and negative lines is in Figure 2 All of them are shown in detail in the figure and will not be described again here.

[0054] Furthermore, in some embodiments, in the intelligent switching remote power supply central office device provided in the present application, the control module 2 can be implemented by a single chip microcomputer, and the monitoring module 4 can be implemented by a sampling circuit 41 and a sensor 42 .

[0055] Specifically, Figure 2 As shown, the sensor 42 can be arranged on the output module 7 or on the relevant circuit, and cooperate with the sampling circuit 41 to collect the current and voltage signals, and transmit them to the single chip microcomputer. Among them, the sensor 42 can include a current sensor and a voltage sensor.

[0056] The intelligent switching remote power supply local end device provided by the present application can monitor whether the output of the whole device (i.e., the intelligent switching remote power supply local end device) is normal in real time through the monitoring module 4. When the output is abnormal, such as when the device has no output, the faulty basic power module can be switched out within microseconds, and the normally working redundant power module can be switched in. And when an electric device is added to the line, the relevant staff can control the redundant power module 3 to be connected in parallel to the line through the communication module 8, increase the total power supply of the line, and ensure the normal power supply of the line.
