[0035] The present invention is described below in conjunction with preferred implementation steps. Figure 1 is a flow chart of a voltage adjustment method for a power core capacitor according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0036] S102, when the power supply control circuit of the communication device enters the core capacity discharge mode, adjusting the opening and closing state of the contactor connected to the battery monitoring module in the power supply control circuit to access the bidirectional power supply control module.

[0037] It should be noted that the present application can be used in the battery capacity control scenario, such as discharging the battery at a constant current, recording the discharge current and time, to calculate the actual capacity of the battery. The power supply control circuit of the communication device enters the capacity discharge mode, which can be but is not limited to a mode for instructing the battery in the power supply control circuit of the communication device to discharge the capacity, and the power supply control circuit is used to power the communication device.

[0038] Furthermore, the battery monitoring module may include but is not limited to at least two battery monitoring modules, and the battery monitoring module is used to monitor the single battery in the communication power system where the communication equipment is located, and is also used to sample the voltage, internal resistance and temperature of the battery, and then upload the collected information to the monitoring system in the communication power system, so as to realize the real-time monitoring of the health status of the single battery. Among them, one battery monitoring module may be used but is not limited to monitor one single battery. Optionally, the monitoring system is used to comprehensively collect various data in the communication power system, issue correct operation instructions after comprehensive analysis, generate corresponding alarms in time, and take necessary protective measures.

[0039] Optionally, the above-mentioned adjustment of the opening and closing state of the contactor connected to the battery monitoring module in the power supply control circuit may include but is not limited to: controlling the first contactor in series with the battery monitoring module in the power supply control circuit to be adjusted to a disconnected state, and controlling the second contactor in series with the bidirectional power supply control module to be adjusted to a closed state, wherein the first contactor is connected in parallel with a diode.

[0040] It should be noted that, in some embodiments, the above-mentioned bidirectional power supply control module may have, but is not limited to, two working modes, including a forward boost output mode and a reverse steady-current output mode. Among them, the above-mentioned forward boost output mode may be, but is not limited to, used to indicate that when the battery core capacity is discharged, the battery terminal voltage is increased by the bidirectional power supply control module, and is higher than the communication power supply output voltage, so that the battery preferentially supplies power to the load (i.e., the communication equipment), thereby achieving the purpose of discharging the battery pack using the communication power supply load. The above-mentioned reverse steady-current output mode is used to indicate that after the battery core capacity is discharged, the battery pack is pre-charged with a small current through the bidirectional power supply control module.

[0041] S104, adjusting the bidirectional power supply control module to enter a boost mode, wherein the bidirectional power supply control module in the boost mode is used to increase the voltage of the battery in the power supply control circuit.

[0042] Optionally, in some embodiments, the above-mentioned adjustment of the bidirectional power supply control module to enter the boost mode may include but is not limited to: increasing the voltage of the battery to a target voltage value, wherein the target voltage value is greater than the output voltage of the communication power supply in the power supply control circuit.

[0043] S106, when it is detected that the power supply control circuit reaches an abnormal condition, controlling the power supply control circuit to exit the core capacitor discharge mode.

[0044] It should be noted that the above-mentioned abnormal conditions can be, but are not limited to, used to indicate abnormal AC input such as: overvoltage, undervoltage, phase loss, power outage, etc. Among them, the above-mentioned phase loss refers to a three-phase AC power supply system in which one or more phases are missing. In a three-phase AC power supply system, there are usually three phases (A, B, C), and phase loss means that there is no current or the current is very small in one or more phases. This may be caused by a power line failure, a circuit breaker tripping, or an internal failure of the equipment. Phase loss may cause the equipment to malfunction or even damage equipment such as motors. Optionally, the above-mentioned control of the power supply control circuit to exit the nuclear capacity discharge mode may include, but is not limited to: the monitoring system controls the power supply control circuit to exit the nuclear capacity discharge mode.

[0045] S108, adjusting the bidirectional power supply control module to enter a steady-current output mode, wherein the bidirectional power supply control module in the steady-current output mode is used to charge the battery.

[0046] Optionally, the above steps are used to control the bidirectional power control module to pre-charge the battery pack with a small current, so that the battery will not be immediately switched to the power supply after the battery reaches the capacity, but will be continued through the booster, which can gradually reduce the voltage at both ends of the bidirectional power control module, and the load will gradually be borne by the power supply, so that the voltage transitions smoothly.

[0047] S110, by adjusting the voltage generated by the bidirectional power control module when charging the battery and the voltage of the power supply in the power supply control circuit, the function value of the control objective function is controlled to be a target threshold, wherein the objective function includes the voltage of the power supply in the power supply control circuit, the voltage of the battery and the voltage generated by the bidirectional power control module when charging the battery, the objective function value is the difference between the power supply voltage and the target voltage, and the target voltage is obtained by adding the battery voltage and the voltage generated by the bidirectional power control module when charging the battery.

[0048] For example, the objective function may be, but is not limited to, the following formula:

[0049] m=U2-U3-E3 (1)

[0050] Among them, the above m is used to represent the value of the objective function, the above U2 is used to represent the voltage of the above power supply, the above U3 is used to represent the voltage generated when the bidirectional power supply control module charges the battery, and the above E3 is used to represent the voltage of the battery.

[0051] Then, the following formula is obtained from the above formula (1):

[0052]

[0053] Among them, U in the above formula (2) is used to represent the input voltage of the switching power supply, D in the above formula (2) is used to represent the power supply duty cycle, L in the above formula (2) is used to represent the inductance, I1 in the above formula (2) is used to represent the current, V in the above formula (3) is used to represent the current, and V in It is used to represent the battery voltage, that is, E3, and R in the above formula (3) l is used to represent the resistance of the bidirectional power supply control module. L in the above formula (3) is used to represent the inductance of the bidirectional power supply control module. The above f(t) is used to represent the adjustable frequency of the power supply. sw (t) is used to represent the adjustable frequency of the bidirectional power supply control module. In this embodiment, by adjusting the above f sw (t) and the above f(t) control the above objective function value to be 0 or close to 0.

[0054] Further, as an optional embodiment, the above-mentioned f can be analyzed with reference to the following examples but is not limited thereto. sw (t) and the above f(t) are adjusted:

[0055]

[0056] m=f(x,y) (7)

[0057] Among them, the above The partial derivatives of the function f(x, y) with respect to x and y, respectively. α and β are adjustable step size parameters used to control the speed of the update. sw Substitute f(t) into the x in the above formula, substitute f(t) into the y in the above formula, and then update x and y according to the slope of the function in the above formula to make f(x, y) close to 0 as soon as possible.

[0058] It should be noted that the above example is an optional example provided for the convenience of explaining the present embodiment. The adjustment of the above objective function may also be implemented with reference to other methods, and the above example does not impose any limitation on this.

[0059] As an optional implementation, the power supply control circuit may be, but is not limited to, Figure 2As shown, it includes: AD / DC power supply MA, bidirectional DC / DC power supply MB, constant current source MC, diode D1, normally closed contactor K1, normally open contactor A, normally open contactor K2B, normally open contactor K3, load current sensor H1, battery current sensor H2, monitoring system P0 and several battery monitoring modules (B1~B24), and the functions of each component are as follows: AD / DC power supply MA is the core component of conventional communication power supply, which is used to convert AC power into 48V DC power to power communication equipment; 48V intelligent DC PDU DC output branch (connected to communication equipment) supplies power for it, and PDU has DC branch current monitoring function, and can also control the on and off of the branch through the monitoring system to realize remote access and exit of communication equipment;

[0060] The bidirectional DC / DC power supply MB has two working modes, forward boost output and reverse steady current output. Specifically, when the battery core capacity is discharged, the bidirectional DC / DC power supply MB increases the battery terminal voltage to be higher than the communication power output voltage. The battery is used to supply power to the load (communication equipment) first, thereby achieving the purpose of discharging the battery pack using the communication power load. After the battery core capacity is discharged, the bidirectional DC / DC power supply MB enters the reverse steady current output mode. The communication power supply pre-charges the battery pack with a small current through the bidirectional DC / DC power supply MB; the online diode D1 is an important protection device for the load (communication equipment) to obtain uninterrupted power supply, and its function is to ensure that the load (communication equipment) is always effectively connected to the battery port; the normally closed contactor K1, the normally open contactor K2A, the normally open contactor K2B, and the normally open contactor K3 are used to switch into the core capacity discharge working mode; the constant current source module MC can output a constant current under the control of the monitoring system to monitor the health of the diode D1 and the normally closed contactor K1; the battery monitoring module (B1~B24) is responsible for the monitoring of the single battery in the communication power supply system, and has the battery single voltage, internal resistance, and temperature sampling functions, and uploads it to the monitoring system P0 in the host to realize the real-time monitoring of the health of the single battery. A battery monitoring module is responsible for monitoring a single battery; the monitoring system P0 is the brain of the all-in-one machine, which is fully responsible for the collection of various system data, and issues correct operation instructions after comprehensive analysis, generates corresponding alarms in time, and takes necessary protection measures.

[0061] Through the present application, the following steps are adopted: when the power supply control circuit of the communication equipment enters the core capacity discharge mode, the opening and closing state of the contactor connected to the battery monitoring module in the power supply control circuit is adjusted to connect the bidirectional power supply control module; the bidirectional power supply control module is adjusted to enter the boost mode, wherein the bidirectional power supply control module in the boost mode is used to increase the voltage of the battery in the power supply control circuit; when it is detected that the power supply control circuit reaches an abnormal condition, the power supply control circuit is controlled to exit the core capacity discharge mode; the bidirectional power supply control module is adjusted to enter the steady current output mode, wherein the bidirectional power supply control module in the steady current output mode is used to charge the battery; by adjusting The bidirectional power supply control module controls the voltage generated when charging the battery and the voltage of the power supply in the power supply control circuit. The function value of the control objective function is the target threshold, wherein the objective function includes the voltage of the power supply in the power supply control circuit, the voltage of the battery and the voltage generated when the bidirectional power supply control module charges the battery. The objective function value is the difference between the voltage of the power supply and the target voltage. The target voltage is obtained by adding the battery voltage and the voltage generated when the bidirectional power supply control module charges the battery. This solves the technical problem of unstable system voltage after battery capacity increase in the related technology, thereby achieving the technical effect of improving the stability of the system voltage.

[0062] As an optional solution, adjusting the on / off state of a contactor connected to the battery monitoring module in the power supply control circuit to access the bidirectional power supply control module includes:

[0063] The first contactor in the power supply control circuit connected in series with the battery monitoring module is controlled to be adjusted to an open state, and the second contactor connected in series with the bidirectional power supply control module is controlled to be adjusted to a closed state, wherein the first contactor is connected in parallel with a diode.

[0064] Optionally, the diode may be, but is not limited to, a protection device for the communication device, used to ensure that the communication device is always effectively connected to the battery port.

[0065] In an embodiment of the present application, by controlling the first contactor in the power supply control circuit that is connected in series with the battery monitoring module to be adjusted to a disconnected state, and controlling the second contactor that is connected in series with the bidirectional power supply control module to be adjusted to a closed state, the purpose of quickly accessing the bidirectional power supply control module is achieved, thereby achieving the technical effect of improving the voltage adjustment efficiency of the power supply core capacitor.

[0066] As an optional solution, adjusting the bidirectional power control module to enter the boost mode includes:

[0067] The voltage of the storage battery is increased to a target voltage value, wherein the target voltage value is greater than the output voltage of the communication power supply in the power supply control circuit.

[0068] In the embodiment of the present application, the technical effect of improving the system voltage stability is achieved by adjusting the bidirectional power control module to enter the boost mode to increase the battery voltage to the target voltage value.

[0069] As an optional solution, after adjusting the bidirectional power supply control module to enter the boost mode, the method further includes:

[0070] The power supply control circuit is determined to have reached an abnormal condition when at least one of the following conditions is detected:

[0071] AC power outage occurs in the power supply control circuit;

[0072] The battery monitoring module is low on power.

[0073] By adopting the embodiment of the present application, the technical effect of improving the system voltage stability is achieved by determining that the power supply control circuit has reached an abnormal condition when at least one of the following situations is detected: an AC power outage occurs in the power supply control circuit; a battery monitoring module is low on power.

[0074] As an optional solution, after adjusting the bidirectional power supply control module to enter the steady current output mode, the method further includes:

[0075] When it is monitored that the charging current is less than a preset value, the first contactor in the open state is controlled to be adjusted to the closed state, and the second contactor in the closed state is controlled to be adjusted to the open state.

[0076] As an optional implementation, the above-mentioned preset value can be but is not limited to the minimum operating current in the circuit. This is only an example and no specific limitation is imposed on the method of determining the preset value. It can be understood that the process of disconnecting the above-mentioned power control module to perform steady-current charging on the battery is only an example and no specific limitation is imposed.

[0077] By adopting the embodiment of the present application, when it is monitored that the charging current is less than a preset value, the first contactor in the disconnected state is controlled to be adjusted to the closed state, and the second contactor in the closed state is controlled to be adjusted to the disconnected state, thereby achieving the purpose of dynamically switching the circuit power supply mode.

[0078] As an optional implementation, when the communication power module is used to supply power to the communication device, the floating charging of the battery block by the communication power module may be, but is not limited to, as follows: Figure 3As shown, the circuit is connected with battery monitoring modules (B1-B24), monitoring system P0, load current sensor H1, battery current sensor H2, normally open contactor K3, normally open contactor K2, normally open contactor K2B, and diode D1. Each battery monitoring module monitors a battery, the normally closed contactor K1 is in a closed state, the bidirectional DC / DC power supply MB and the constant current source MC are both in a shutdown state and do not intervene in the system operation, and the AC / DC power supply MA supplies power to the PDU DC output branch (connected to the communication equipment) to float charge the battery.

[0079] As an optional implementation, when the power fails, it can be referred to but not limited to: Figure 4 The following example is shown: Figure 4 As shown, the circuit is connected with battery monitoring modules (B1-B24), monitoring system P0, load current sensor H1, battery current sensor H2, normally open contactor K3, normally open contactor K2, normally open contactor K2B, normally closed contactor K1, diode D1, bidirectional DC / DC power supply MB, AD / DC power supply MA, PDU DC output branch (connected to communication equipment), constant current source MC, and each battery monitoring module monitors a battery; it should be noted that when the AC input is abnormal (overvoltage, undervoltage, phase loss, power outage), the battery acts as a backup power supply and starts to supply power to the load.

[0080] As an optional implementation, the process of the battery core capacity supplying power to the communication device can be but is not limited to referring to the following Figure 5 The following example is shown: Figure 5 As shown, the monitoring system P0 controls the normally closed contactor K1 to open, controls the normally open contactors K2 and K2B to close, controls the bidirectional DC / DC power supply MB to start up and enter the boost mode, and the bidirectional DC / DC power supply MB increases the battery terminal voltage (higher than the communication power supply output voltage) to give priority to powering the load.

[0081] As an optional implementation, Figure 6 As shown, when the core capacity discharge stops, the monitoring system P0 will control the bidirectional DC / DC power supply MB to work in reverse, automatically switch to the steady current charging mode, and charge the battery. The voltage of the battery after discharge is too low, and the purpose of steady current charging is to prevent the communication power supply from charging the battery with too large an initial current. Precharging it by the bidirectional DC / DC power supply MA is more conducive to extending the service life of the battery pack.
