The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] Firstly, such as Figure 1 As shown, a power supply circuit for a repeater system is provided. The circuit includes a power supply module, a control module, and a float charge management module. The power supply module is connected to the float charge management module through the control module. Figure 2 As shown, the power module includes a main power module and an auxiliary power module, which are connected in parallel. The control module is used to select either the main power module or the auxiliary power module to supply power to the repeater system based on the power supply status of the power module. The float charging management module is used to charge the auxiliary power module based on the voltage output by the main power module when the main power module supplies power to the repeater system.

[0023] It should be noted that the power supply circuit includes a power module, a control module and a floating charge management module, wherein the power module is connected with the floating charge management module through the control module, the power module includes a main power module and a backup power module, and the main power module and the backup power module are connected in parallel, the control module selects any one of the main power module and the backup power module to supply power to the transfer station system according to the power supply condition of the power module, the backup power module can seamlessly switch power supply when the main power module fails, avoiding system downtime, wherein when the backup power module fails or needs to be upgraded, technicians do not need to turn off the main power module, and can directly plug and replace the module with power on, avoiding the problem that the system must be shut down and powered off in traditional maintenance, shortening the maintenance window period, and reducing economic losses and safety hazards caused by shutdown. In addition, the floating charge management module is used to charge the backup power module based on the voltage output by the main power module when the main power module supplies power to the transfer station system, realizing energy recovery, and the backup power module can store the regenerated energy of the main power module, which enables the backup power module to quickly switch to a power supply state when the main power module is abnormal or powered off, ensuring the continuous operation of the load device, improving the reliability and stability of system power supply, and also realizing reasonable allocation and utilization of energy, the main power module can dynamically adjust the charging power according to the power state of the backup power module, avoiding overcharging or undercharging, which helps to prolong the service life of the backup power module, makes the system more efficient and orderly in energy scheduling, reduces unnecessary energy loss, and thus optimizes the performance of the power supply system as a whole, meeting the demand of the device for stable power supply.

[0024] Through the circuit provided by the first aspect, another power module can be used to continue power supply when one of the power modules fails, and by arranging two groups of power modules, stable and reliable power supply can be ensured in various situations, and normal work can be maintained in long-time operation, avoiding communication interruption of the transfer station caused by power failure, enabling the transfer station to operate stably in various complex environments, providing reliable protection for private network communication. In addition, when the main power module is working normally, the floating charge management module charges the backup power module based on the voltage output by the main power module, avoiding energy waste and improving the overall energy efficiency of the system.

[0025] In a possible implementation manner, as Figure 3As shown, the control module comprises a first chip U1, a second chip FG1, a first transistor Q1, a transistor module 100, the power module is connected with the second chip FG1, the first chip U1 is connected with the second chip FG1 through the first transistor Q1, and the transistor module 100 is connected between the first chip U1 and the second chip FG1; the control module is used for selecting any one of the main power module and the auxiliary power module to supply power for the transfer platform system according to the power supply condition of the power module, and the control module comprises: the second chip FG1 is used for sending a first control signal to the first transistor Q1 according to the power supply condition of the power module, so as to control the on and off states of the first transistor Q1; the first chip U1 is used for sending a second control signal to the transistor module 100 according to the on and off states of the first transistor Q1, so as to control the on and off states of the transistor module 100, thereby selecting any one of the main power module and the auxiliary power module to supply power for the transfer platform system.

[0026] It should be noted that the control module includes a first chip U1, a second chip FG1, a first transistor Q1, a transistor module 100, and a power module connected with the second chip FG1. The first chip U1 is connected with the second chip FG1 through the first transistor Q1, and the transistor module 100 is connected between the first chip U1 and the second chip. The second chip FG1 is configured to send a first control signal to the first transistor Q1 according to the power supply condition of the power module, so as to control the on and off states of the first transistor Q1. The first chip U1 is configured to send a second control signal to the transistor module 100 according to the on and off states of the first transistor Q1, so as to control the on and off states of the transistor module 100, thereby selecting any one of the main power module and the auxiliary power module to supply power to the transfer station system. For example, when the main power module of the power module normally supplies power, the PG signal of the second chip FG1 is high at 5V, the first control signal triggering the transistor to turn on is sent to the first transistor Q1, when the first transistor Q1 is turned on, the voltage detected by the third pin of the first transistor Q1 is pulled down to less than 1V, so that the sixth pin of the first chip U1 is immediately pulled down to a low level, the second control signal controlling the transistor module 100 to turn off is sent to the transistor module 100, so that the transistor module 100 is turned off, and the main power module supplies power to the transfer station system. When the main power module of the power module fails to output or the mains power fails to output normal voltage, the PG signal of the second chip FG1 is reduced to a low level, the first control signal triggering the transistor to turn off is sent to the first transistor Q1, when the first transistor Q1 is turned off, the voltage detected by the third pin of the first transistor Q1 becomes high and is greater than 1.13V, at this time, the sixth pin of the first chip U1 is raised to a high level, the second control signal controlling the transistor module 100 to turn on is sent to the transistor module 100, so that the transistor module 100 is turned on, and the auxiliary power module supplies power to the transfer station system. By setting the switching mechanism of the main power module and the auxiliary power module, stable and reliable power supply can be ensured under various conditions, and normal work can be maintained for a long time, avoiding communication interruption caused by power failure of the transfer station, so that the transfer station can stably operate in various complex environments, and reliable protection is provided for private network communication.

[0027] In a possible implementation manner, as shown in Figure 3 The control module further includes a voltage monitoring unit 200 connected with the first chip U1. The voltage monitoring unit 200 is configured to detect the input voltage of the control module to ensure that the input voltage is within a preset safe range. The voltage monitoring unit 200 includes a first resistor R17, a second resistor R18, a third resistor R19, and a first capacitor C24. The second resistor R18, the third resistor R19, and the first capacitor C24 are connected in parallel and then connected between the first resistor R17 and the first chip U1.

[0028] The control module further comprises a voltage monitoring unit 200 connected to the first chip U1, which is used to detect the input voltage of the control module to ensure that the input voltage is within the preset safety range. The voltage monitoring unit 200 comprises a first resistor R17, a second resistor R18, a third resistor R19 and a first capacitor C24. The second resistor R18, the third resistor R19 and the first capacitor C24 are connected in parallel and then connected between the first resistor R17 and the first chip U1. Specifically, by detecting the voltage between the first capacitor C24 and the first chip U1, i.e. the input voltage of the control module, when the input voltage is greater than 19.5V, the control module cuts off the output power supply, and when the input voltage is below 18V, the control module only receives normal incoming calls, so that the power module supplies power to the transfer station system. In addition, the first resistor R17, the second resistor R18 and the third resistor R19 form a voltage dividing network, which accurately adjusts the voltage between the first capacitor C24 and the first chip U1. The first capacitor C24 is a filter capacitor used to filter high-frequency noise after voltage division by the first resistor R17, the second resistor R18 and the third resistor R19, so that the voltage input to the first chip U1 is more stable, avoiding interference with the internal logic of the first chip U1. By setting the input voltage monitoring protection mechanism, the system can quickly respond when the input voltage is abnormal, avoid damage to the transfer station system due to unstable power supply, ensure the continuous and safe operation of the system, and comprehensively improve the power management level. In addition, through accurate monitoring and action, damage and data loss can be prevented, the system life can be prolonged, the performance of the power circuit can be optimized, and the power circuit can work stably.

By controlling the on and off states of the second transistor Q3 and the third transistor Q4, the main power module and the auxiliary power module are selected to supply power to the transfer station system. By setting two transistors, when one of the transistors has a slight performance decline, the other transistor can share more current, and the basic function can still be maintained, which improves the system fault tolerance to a certain extent, reduces the risk of system failure caused by a single device failure, and each transistor shares current, the loss on the conduction resistance is dispersed, the heat of a single tube is reduced, the device aging is delayed, the system reliability and service life are improved, which is beneficial to the long-term stability of the circuit. In addition, when a large current is output, it can respond faster to sudden changes in load current, such as sudden load increase, and quickly supplement the current to maintain voltage stability, reduce voltage fluctuations, and make the transfer station system work more stably.

By detecting the sampling voltage, a safe charging control mechanism is realized. For example, the auxiliary power module can be a lead-acid battery, the charging current is limited to 1.5A, and when the voltage of the auxiliary power module is higher than 12.5V, the lead-acid battery enters a constant-voltage floating charging state, which not only maintains the power of the auxiliary power module, but also reduces the risk of overcharging, adapts to the characteristics of the lead-acid battery, prolongs the service life, improves the charging safety and efficiency, and stabilizes the energy storage of the battery.
