[0039] The inventors discovered during their research on power supplies, hydraulic support controllers, hydraulic support control systems, and hydraulic supports that the power supply can power the hydraulic support controller, which in turn powers peripheral devices. However, as the number of peripheral devices increases, the power consumption of the hydraulic support controller increases, consequently increasing the load on the power supply and potentially leading to power overload.

[0040] It should be noted that the peripheral equipment mentioned here can be the electrical equipment of the hydraulic support, including equipment related to the transmission and / or consumption of electrical energy, as well as equipment related to the control, protection, and / or metering of electrical energy. In other words, the peripheral equipment can be used to realize the transmission, consumption, control, protection, and / or metering of electrical energy in the hydraulic support. Here, equipment related to the transmission of electrical energy may include transformers; equipment related to the consumption of electrical energy may include indicator lights, wireless signal converters, motors, etc.; equipment related to the control of electrical energy may include solenoid valves, etc.; equipment related to the protection of electrical energy may include protective relays, surge arresters, etc.; and equipment related to the metering of electrical energy may include sensors, etc.

[0041] In order to at least solve one of the technical problems existing in the prior art or related art, the present invention provides a power supply, a hydraulic support controller, a hydraulic support control system, and a hydraulic support. The power supply can monitor its own power consumption information. Through communication between the first communication unit of the power supply and the second communication unit of the hydraulic support controller, the power consumption information of the power supply can be transmitted to the second monitoring unit of the hydraulic support controller. The second monitoring unit can adjust the power consumption of the hydraulic support controller according to the power consumption information of the power supply to control the load of the power supply.

[0042] Because the hydraulic support controller adjusts its power consumption based on the power consumption information monitored by the power supply, it achieves cooperation between the power supply and the hydraulic support controller. This prevents power overload caused by increased power load before the power supply becomes overloaded. When the power supply powers multiple hydraulic support controllers, it can reduce the load on one or more controllers, ensuring that the more critical controllers can stably obtain power from the power supply, thus enabling them to operate stably. In this way, the beneficial effect of stable operation of both the power supply and the hydraulic support controllers is achieved, and the power supply's energy is utilized effectively.

[0043] The following reference Figures 1 to 9 The present invention describes a power supply 10, a hydraulic support controller 20, a hydraulic support control system, and a hydraulic support according to some embodiments thereof.

[0044] See Figure 1 The hydraulic support control system provided by this invention includes: a power supply 10, a hydraulic support controller 20, and peripheral devices 30. The peripheral devices 30 may include stroke sensors, pressure sensors, infrared sensors, tilt sensors, solenoid valve actuators, wireless signal converters, status warning lights, and positioning base stations for personnel location, etc. The power supply 10 can be connected to the hydraulic support controller 20, and the hydraulic support controller 20 can be connected to the peripheral devices 30. Figure 1 This is merely an illustrative description. In actual use, one power supply 10 can connect to two or more hydraulic support controllers 20, and each hydraulic support controller 20 can connect to two or more peripheral devices 30.

[0045] See Figure 2 The power supply 10 provided in one embodiment of the present invention is connected to a hydraulic support controller 20 and is used to supply power to the hydraulic support controller 20. It includes: a first monitoring unit 11 for monitoring the power consumption information of the power supply 10; and a first communication unit 12 connected to the first monitoring unit 11 for sending the power consumption information to a second communication unit 22 in the hydraulic support controller 20, so that the second monitoring unit 21 in the hydraulic support controller 20 adjusts the power consumption of the hydraulic support controller 20 according to the power consumption information to control the load of the power supply 10.

[0046] It should be noted that the power consumption information here may include the output voltage and / or output current of power supply 10.

[0047] In an exemplary embodiment, the power supply 10 can be an intrinsically safe power supply, such as an intrinsically safe DC power supply. The hydraulic support controller 20 includes a second monitoring unit 21 and a second communication unit 22. The first communication unit 12 and the second communication unit 22 can be connected via wired connection through a controller area network bus (CAN bus) or wireless connection. The first monitoring unit 11 can monitor the output voltage and output current in real time. Correspondingly, the second monitoring unit 21 can adjust the power supply 10 in real time, thereby controlling the load of the power supply 10 to more effectively reduce or even avoid overload of the power supply 10 and ensure stable operation of the power supply 10.

[0048] In an exemplary embodiment, multiple hydraulic support controllers 20 can work collaboratively. Specifically, each hydraulic support controller 20 may have an importance level. During adjustment, the power consumption of hydraulic support controllers 20 with relatively lower importance levels can be reduced first, thereby ensuring that hydraulic support controllers 20 with relatively higher importance levels can operate normally. Here, the importance level can be preset.

[0049] Further, see Figure 3 The first communication unit 12 is also used to receive the starting voltage and / or starting current of the device to be started powered by the hydraulic support controller 20. The first monitoring unit 11 includes a starting judgment subunit 13, which is connected to the first communication unit 12 and is used to determine whether the starting of the device to be started will cause the power supply 10 to overload based on the power consumption information of the power supply 10 and the starting voltage and / or starting current of the device to be started. When the power supply 10 is overloaded, the first communication unit 12 notifies the hydraulic support controller 20 to stop starting the device to be started.

[0050] In an exemplary embodiment, the hydraulic support controller 20 can be connected to multiple devices to be started. The hydraulic support controller 20 can send the starting voltage and starting current of the devices to be started to the first communication unit 12 via the second communication unit 22, and the first communication unit 12 forwards the information to the start-up judgment subunit 13. The devices to be started can be peripheral devices powered by the hydraulic support controller 20. The start-up judgment subunit 13 also obtains the output voltage and output current monitored by the first monitoring unit 11. To reduce or even avoid overload of the power supply 10, the start-up judgment subunit 13 can make a judgment before the devices to be started are started. The correspondence between the voltage of the peripheral devices, the current of the peripheral devices, the output voltage and output current of the power supply 10 before the devices to be started are started, and the output voltage and output current of the power supply 10 after the devices to be started are started can be determined in advance. The start-up judgment subunit 13 can use this correspondence to estimate the output voltage and output current of the power supply 10 after the devices to be started are started. The estimated output voltage can be compared with the power supply overload voltage. When the estimated output voltage reaches the power supply overload voltage, a voltage overload can be determined. The estimated output current can be compared with the power supply overload current. When the estimated output current is greater than the power supply overload current, a current overload can be identified. Here, the power supply overload voltage and power supply overload current are the voltage and current that cause power supply 10 to overload, respectively. If a potential voltage or current overload is identified, power supply 10 can be prevented from overloading by stopping the start of the device to be started. This can reduce or even prevent damage to power supply 10, and also avoid the problem of the hydraulic support controller 20 powered by power supply 10 malfunctioning due to power outage or power supply failure caused by power supply overload.

[0051] Further, see Figure 4 The power supply 10 also includes: a conversion unit 14 for converting AC power input to the power supply 10 into DC power; and an output regulation unit 15 connected to the conversion unit 14 for regulating the output voltage and output current of the power supply 10 without changing the output power of the power supply 10.

[0052] In an exemplary embodiment, the conversion unit 14 can convert the AC power input to the power supply 10 into DC power, for example, converting 127V AC power into 12V DC power. In practical use, due to potential power loss in the power supply line from the power supply 10 to the hydraulic support controller 20, the voltage actually output by the power supply 10 to the hydraulic support controller 20 may not meet the needs of the hydraulic support controller 20. For example, when the hydraulic support controller 20 outputs 5V, the voltage reaching the hydraulic support controller 20 may be 4.8V, causing the hydraulic support controller 20 to malfunction. To avoid such a problem, the output voltage of the power supply 10 can be increased by the output adjustment unit 15, thereby ensuring stable operation of the hydraulic support controller 20 while also ensuring that the power supply 10 operates at its original output power before adjustment.

[0053] Further, see Figure 5 The first monitoring unit 11 includes: a power demand acquisition subunit 16, connected to the first communication unit 12, for acquiring the actual voltage value, the actual current value, and the power demand value of the hydraulic support controller 20 through the first communication unit 12; a first control subunit 17, connected to the power demand acquisition subunit 16 and the output adjustment unit 15, for calculating the actual power value of the hydraulic support controller 20 based on the actual voltage value and the actual current value, determining whether the actual power value is greater than or equal to the power demand value, and issuing a power increase command to the output adjustment unit 15 when the determination result is negative; the output adjustment unit 15 is also used to increase the output power of the power supply 10 within a predetermined time period (e.g., within 1 millisecond) when the power increase command is received, so that the actual power value is equal to or higher than the power demand value.

[0054] In an exemplary embodiment, the actual voltage and current values ​​of the hydraulic support controller 20 can be monitored by the second monitoring unit 21. The second monitoring unit 21 can also obtain the power demand value of the hydraulic support controller 20 through external input, pre-storage, or other means. The power demand value and the monitored actual voltage and current values ​​can be forwarded to the first communication unit 12 through the second communication unit 22 of the hydraulic support controller 20. The actual voltage and current values ​​can be monitored in real time, so that the first control subunit 17 can determine in real time whether the actual power value is greater than or equal to the power demand value. In order to promptly increase the output of the power supply 10 when the actual power value cannot reach the power demand value, the hydraulic support controller 20 can be guaranteed to work normally, thereby improving the working stability of the power supply 10 and the hydraulic support controller 20.

[0055] It should be noted that when power supply 10 cannot meet the power supply requirements of hydraulic support controller 20, increasing the number of power supplies 10 would lead to increased costs. The power supply 10 used in this embodiment of the invention can ensure the normal startup of hydraulic support controller 20 without increasing the number of power supplies. Combined with the method described above, power consumption can be reduced by adjusting the power consumption of one or more hydraulic support controllers 20 to ensure that high-critical hydraulic support controllers 20 can operate normally. Therefore, the power supply 10 of this invention also has the beneficial effect of saving costs.

[0056] Further, see Figure 6 The power supply 10 also includes an output protection unit 18, which is connected to the output regulation unit 15 and is used to provide overload protection for the power supply 10.

[0057] In an exemplary embodiment, the conversion unit 14, the output regulation unit 15, the output protection unit 18, and the output terminal (not shown) of the power supply 10 are connected in sequence. The output protection unit 18 can determine voltage overload and current overload. When a voltage overload or current overload is detected, it can disconnect the connection with the output terminal of the power supply 10 in a timely manner to stop the power supply 10 from supplying power, thereby reducing or even avoiding damage to the power supply 10.

[0058] In another embodiment, the hydraulic support controller 20 is connected to and powered by the power supply 10. See also Figure 2 The hydraulic support controller 20 includes: a second communication unit 22, used to receive power consumption information of the power supply 10 sent by the first communication unit 12 in the power supply 10, the power consumption information being obtained by the power supply 10 through the first monitoring unit 11; and a second monitoring unit 21, connected to the second communication unit 22, used to monitor the power consumption of the hydraulic support controller 20, and adjust the power consumption of the hydraulic support controller 20 according to the power consumption information to reduce or even avoid overload of the power supply 10.

[0059] In an exemplary embodiment, since the hydraulic support controller 20 serves as the load of the power supply 10, the output power of the power supply 10 will also increase when the power consumption of the hydraulic support controller 20 increases. When the power consumption of the hydraulic support controller 20 increases to the point that the power supply 10 is overloaded, the power supply 10 will be protected against power failure or the power supply will be damaged. To reduce or even avoid the occurrence of power supply 10 failure or damage, the power consumption information of the power supply 10 can be monitored in real time, and the second monitoring unit 21 can adjust the power consumption of the hydraulic support controller 20 in real time according to the power consumption information of the power supply 10 to control the load of the power supply 10, thereby reducing or even avoiding power supply 10 overload. When multiple hydraulic support controllers 20 exist, the power consumption of one or more hydraulic support controllers 20 can be reduced and the power consumption of one or more hydraulic support controllers 20 can be increased. The hydraulic support controllers 20 with increased and decreased power consumption can be flexibly specified as needed.

[0060] Furthermore, the hydraulic support controller 20 includes multiple functional units, see [link to relevant documentation]. Figure 7 The second monitoring unit 21 includes: a working status judgment subunit 23, used to determine whether the hydraulic support controller 20 is in a working state or a non-working state based on the power consumption of the hydraulic support controller 20; and a second control subunit 24, used to shut down functional units with an importance level lower than a predetermined level when the hydraulic support controller 20 is in a non-working state. A second communication unit 22 can be connected to both the working status judgment subunit 23 and the second control subunit 24, so that the working status judgment subunit 23 can obtain the power consumption and line loss power consumption of the peripheral devices of the hydraulic support controller 20 through the second communication unit 22, and the second control subunit 24 can communicate with other functional units or peripheral devices through the second communication unit 22 to issue functional unit shutdown commands to shut down the corresponding functional units or peripheral devices.

[0061] In an exemplary embodiment, the functional units of the hydraulic support controller 20 may include: a second monitoring unit 21, a second communication unit 22, a working status judgment subunit 23, a second control subunit 24, and one or more peripheral device control units (not shown in the figure) for controlling peripheral devices. A power consumption value can be preset; when the current power consumption of the hydraulic support controller 20 is lower than the preset power consumption value, it can be determined that the hydraulic support controller 20 is currently in a non-working state. Energy-saving operation can be achieved by shutting down the functional units. An importance level can be preset for the functional units to ensure that functional units with a predetermined importance level can still operate normally during energy-saving operation. Time-sharing control can be used for energy-saving operation, for example, shutting down the first functional unit at a first moment and shutting down the second functional unit at a second moment, etc. The time-sharing control method can be flexibly adjusted as needed to achieve flexible control of the power consumption of the hydraulic support controller 20. Alternatively, time-sharing control can also be used to execute the operation of one or more units in the exemplary embodiment, which will not be elaborated here.

[0062] Further, see Figure 8 The hydraulic support controller 20 is connected to the peripheral device 30 and is used to supply power to the peripheral device 30. The hydraulic support controller 20 also includes a peripheral device monitoring unit 25, which is located at the peripheral device power supply interface (not shown in the figure) of the hydraulic support controller 20 and is connected to the second communication unit 22. It is used to monitor the power consumption of the peripheral device 30 and transmit the monitored power consumption of the peripheral device 30 to the second monitoring unit 21 through the second communication unit 22. The power consumption of the hydraulic support controller 20 includes the power consumption of the hydraulic support controller 20 itself and the power consumption of the peripheral device 30.

[0063] In an exemplary embodiment, the hydraulic support controller 20 can be connected to multiple peripheral devices 30. The peripheral devices 30 can act as loads on the hydraulic support controller 20, and the power consumption of the hydraulic support controller 20 increases as the number of peripheral devices 30 increases. Since the power consumption of the hydraulic support controller 20 includes both its own power consumption and the power consumption of the peripheral devices 30, the power consumption of the peripheral devices 30 is also considered when adjusting the power consumption of the hydraulic support controller 20. Because the power consumption of the peripheral devices 30 is taken into account during power consumption adjustment, i.e., more comprehensive information is considered, the adjustment result will be more accurate, and overload of the power supply 10 can be more effectively reduced or even avoided.

[0064] Further, see Figure 9The hydraulic support controller 20 also includes a circuit loss monitoring unit 26, which is located at the power input terminal of the hydraulic support controller 20 (not shown in the figure) and connected to the second communication unit 22. It is used to monitor the power loss power consumption of the power supply line from the power supply 10 to the hydraulic support controller 20, and transmit the monitored power loss power consumption of the power supply line to the second monitoring unit 21 through the second communication unit 22. The power consumption of the hydraulic support controller 20 includes the power consumption of the hydraulic support controller 20 itself and the power loss power consumption of the power supply line.

[0065] In an exemplary embodiment, the second monitoring unit 21 obtains the power loss of the power supply line by dividing the power supply time. The power demand value can then be determined as the power loss of the power supply line plus the power of the hydraulic support controller 20 itself. In this case, when the first control subunit 17 determines whether the actual power value is greater than or equal to the power demand value, it will consider the power loss of the power supply line. Therefore, even if there is a power loss during the power supply process, the output adjustment unit 15 can adjust the output to ensure that the hydraulic support controller 20 obtains the required power, further guaranteeing the stable operation of the hydraulic support controller 20.

[0066] The hydraulic support controller 20 provided in this embodiment of the invention can obtain power consumption information of the power supply 10, including output voltage and output current. The hydraulic support controller 20 can adjust its own power consumption in a timely manner based on the power consumption information of the power supply 10. Therefore, the power supply 10 and the hydraulic support controller 20 can cooperate effectively to avoid overload caused by increased load before the power supply 10 becomes overloaded. In this case, since the power supply 10 will not be cut off due to overload and can continuously supply power to the hydraulic support controller 20, the beneficial effect of stable operation of both the power supply 10 and the hydraulic support controller 20 can be achieved.

[0067] In another embodiment, the power supply 10 and the hydraulic support controller 20 of the exemplary embodiment may be located in the hydraulic support control system.

[0068] Since the hydraulic support control system provided in this embodiment has the power supply 10 and hydraulic support controller 20 provided in any of the above embodiments, the hydraulic support control system has all the beneficial effects of the power supply 10 and hydraulic support controller 20 provided in any of the above embodiments, which will not be repeated here.

[0069] In another embodiment, the power supply 10, the hydraulic support controller 20, and the hydraulic support control system of the exemplary embodiment may be disposed in the hydraulic support.

[0070] Since the hydraulic support provided in this embodiment has the power supply 10, hydraulic support controller 20 and hydraulic support control system provided in any of the above embodiments, the hydraulic support has all the beneficial effects of the power supply 10, hydraulic support controller 20 and hydraulic support control system provided in any of the above embodiments, which will not be repeated here.

[0071] The following reference Figures 10 to 12 A control method according to some embodiments of the present invention is described, which is used to achieve power supply stability control of power supply 10.

[0072] See Figure 10 An exemplary control method, applied to a hydraulic support control system, may include the following steps:

[0073] S101: The first monitoring unit in the power supply monitors the power consumption information of the power supply;

[0074] S102: The first communication unit sends the power consumption information to the second communication unit in the hydraulic support controller;

[0075] S103: The second communication unit receives the power consumption information sent by the first communication unit;

[0076] S104: The second monitoring unit adjusts the power consumption of the hydraulic support controller according to the power consumption information to control the power load.

[0077] Specifically, the power supply may be equipped with a first monitoring unit and a first communication unit, and the hydraulic support controller may be equipped with a second monitoring unit and a second communication unit, with the first communication unit connected to the second communication unit.
