Description

Technical Field

[0001] The present invention belongs to the field of intelligent backup power, and specifically relates to a 5G base station differentiated backup power intelligent control device. Background Art

[0002] The power supply system of the communication base station uses an AC-DC switching power supply to power the communication equipment. When the city power is cut off, batteries are used as backup power supplies to provide backup power for each communication device. The backup power service requirements of different operators for the same communication base station are inconsistent, and the backup power solutions vary greatly, resulting in the inability to unify the backup power of the base station. At the same time, the power consumption of 5G communication equipment is 3.5 times that of 4G communication equipment, which greatly shortens the backup power time of the battery. Long-term backup power will cause the battery to over-discharge and cause irreversible damage to the battery. In a specific time period, the communication service volume accessed by most 5G base stations is low, especially in remote areas where base stations have no communication service access at all, and the communication equipment of the base station is still fully turned on, resulting in a huge waste of energy.

[0003] At present, 5G base station differentiated backup power mostly adopts two kinds of equipment: intelligent circuit breakers and time-delay circuit breakers. Intelligent circuit breakers realize the backup power supply of 5G communication equipment by remotely controlling the opening and closing of circuit breakers; however, this equipment needs the help of remote management platform and third-party power monitoring system to realize differentiated backup power. The time-delay circuit breaker can delay the opening of the circuit breaker through its own interlocking device after the mains power outage is switched to battery power supply to realize the backup power control function; however, this device has a single function and cannot monitor input and output power parameters, cannot distinguish the power supply status of mains power and diesel generator, cannot perform user control according to the backup power service requirements of different operators, and cannot effectively protect the battery. Failures of the above two types of equipment themselves will affect the backup power supply of communication equipment. Summary of the invention

[0004] The purpose of the present invention is to provide a 5G base station differentiated backup power intelligent control device, which supplies backup power to communication equipment by controlling the on and off of the DC48V contactor. The device has the functions of controlling the on and off of each user circuit, power monitoring and status monitoring. It can supply backup power to the communication equipment according to the conditions such as scheduled on and off, backup power duration, backup power voltage, backup power quantity, exemption time and oil generator power purchase situation, so as to realize differentiated backup power intelligent control of 5G base stations.

[0005] In order to solve the above problems existing in the prior art, the technical solution adopted by the present invention is:

[0006] A 5G base station differentiated backup power intelligent control device includes a status monitoring unit, a data acquisition unit, a single-chip microcomputer, an execution unit, a communication module and a power conversion unit.

[0007] The status monitoring unit is electrically connected to the single-chip microcomputer, and is used to perform real-time monitoring of the mains input unit, the oil engine generating unit, and the DC generating unit, determine the connected mains status signal, the oil engine status signal, and the DC status signal, and send the mains status signal, the oil engine status signal, and the DC status signal to the single-chip microcomputer.

[0008] The data acquisition unit is electrically connected to the single-chip microcomputer, and is used to collect power supply information of each sub-user and send the power supply information to the single-chip microcomputer. The sub-user is a mobile / telecom / Unicom communication device, and the power supply information includes current information, voltage information, and power information of each sub-user.

[0009] The single chip microcomputer is used to receive the mains power status signal sent by the second digital-to-analog conversion module and determine the mains power supply status. When the mains power is cut off, the single chip microcomputer controls the execution unit to connect the backup power circuit.

[0010] The backup power supply is electrically connected to the power distribution unit through the execution unit, and the execution unit is used to receive instructions issued by the single-chip microcomputer and execute corresponding actions to control the power distribution unit to supply backup power to the communication equipment.

[0011] The communication module is electrically connected to the single-chip microcomputer, and is used to communicate with the operation and maintenance platform, and send device data to the operation and maintenance platform in real time, so as to facilitate remote monitoring and management of the platform.

[0012] The working power supply supplies power to the single-chip microcomputer, the data acquisition unit, the communication module and the execution unit through the power conversion unit.

[0013] Furthermore, the data acquisition unit includes a voltage acquisition module and two Hall sensors. The voltage acquisition module is used to collect the backup power voltage of each user. The Hall sensors are connected to the users one by one. The data acquisition unit is electrically connected to the single-chip microcomputer through the first digital-to-analog conversion module. The data acquisition unit is used to collect power supply information of each household, which can realize the backup power control function of each user, and can monitor the total input and the power distribution parameters and metering functions of each user in real time, and perform differentiated backup power according to different user needs; the duration is set manually through the human-computer interaction module, and the clock module sets the time period according to the 5G business requirements to control the power supply of communication equipment, thereby reducing unnecessary energy loss.

[0014] Furthermore, the state monitoring unit is electrically connected to the single-chip microcomputer through the second digital-to-analog conversion module. The state monitoring unit includes an AI monitoring module, a DI monitoring module, an output switch state monitoring module and a contactor state monitoring module. The AI ​​monitoring module includes three AC power failure monitoring sensors, which are respectively used to monitor the AI ​​analog quantity of the mains input unit, the AI ​​analog quantity of the oil engine generating unit and the AI ​​analog quantity of the DC generating unit. The AI ​​analog quantity of the mains input unit outputs DC5V±0.5V to judge that the mains is normal, outputs 2.5V±0.5V to judge that the mains is out of power, and less than 0.5V is when the device is not connected or the device is faulty. The DI monitoring module is used to monitor the state of the mains three-phase power supply. If the three phases are out of power at the same time, it is judged that the mains is out of power, otherwise the mains power supply is normal. When the AI ​​monitoring module and the DI monitoring module receive signals at the same time, the entire device functions normally. The contactor state monitoring module is used to monitor the on-off of the DC48V contactor to judge whether the supply and backup circuit is connected. The output switch state monitoring module monitors the on-off state of each branch output by monitoring the circuit breaker.

[0015] Further, the execution unit includes a DC48V contactor, a DC12V relay and a circuit breaker. The backup power supply is electrically connected to the power distribution unit through the DC48V contactor and the circuit breaker. The single-chip microcomputer controls the on and off of the DC48V contactor by controlling the DC12V relay to supply backup power to the communication equipment. The strong and weak electricity are completely isolated, and the system is safer and more reliable. The DC48V contactor is provided with multiple DC48V contactors, and the multiple DC48V contactors are connected to the connected sub-users one by one. In response to the execution signal of the single-chip microcomputer, the circuit breaker is connected to the DC48V contactor, and corresponds to the branch connected to the same DC48V contactor one by one. In response to the execution signal of the single-chip microcomputer, each sub-user is connected to a maximum of eight branches. The DC48V contactor is a normally closed type. When the equipment fails, it does not affect the normal operation of the communication equipment. The equipment has an execution unit fault self-checking function, and can judge the execution unit fault through equipment operation instructions and conditions such as the front and rear voltages of the DC48V contactor. The execution unit controls the on and off of the DC48V contactor to realize the backup power supply to the sub-user.

[0016] Furthermore, it also includes a human-computer interaction module, a storage unit and a clock module which are electrically connected to the single-chip microcomputer respectively. The human-computer interaction module is used to receive the power supply and distribution information sent by the single-chip microcomputer and display the power supply and distribution information. The storage unit is used to store the power supply information sent by the single-chip microcomputer. The clock module is used for backup power timing and can perform backup power according to the duration.

[0017] Furthermore, the communication module is connected to the human-computer interaction module and the operation and maintenance platform respectively, and is used to receive command information issued by the human-computer interaction module and the operation and maintenance platform, and send the command information to the single-chip microcomputer. The communication module includes an RS485 communication module and a 4G module, which can realize two communication functions of RS485 communication and 4G wireless network. The 4G module uses the full-network CAT1 module EC200S to facilitate user use.

[0018] Furthermore, the power conversion unit is electrically connected to the single-chip microcomputer, the data acquisition unit and the communication module respectively. The power conversion unit specifically includes a DC48V-DC12V converter, a DC12V-DC5V converter for powering the communication module, a DC12V-DC3.3V converter for powering the single-chip microcomputer, and a DC12V-±12V converter for the Hall sensor to detect current.

[0019] Furthermore, in the case of a city power outage, the backup duration, backup voltage or predetermined power can be set through the human-computer interaction module. The data acquisition module collects the power supply information of each branch to realize voltage backup and power backup. The clock module can set the backup duration of the branch to realize time backup. Through the three backup modes, the backup parameters can be set according to customer needs. After the backup demand is met, the single-chip microcomputer controls the circuit breaker to automatically disconnect the communication equipment to avoid excessive discharge of the battery, effectively protect the battery, and extend the service life of the battery. By setting the data acquisition module, the power supply voltage of the branch is monitored, and it has overvoltage and undervoltage shutdown protection functions. When the power supply voltage exceeds the set protection limit, the back-end communication equipment can be automatically disconnected to avoid damage to the communication equipment working under abnormal voltage. The data acquisition module monitors the power supply current of the sub-user. When the sub-user is detected to be overloaded or short-circuited, the single-chip microcomputer can automatically shut down the DC48V contactor of the overloaded or short-circuited sub-user, thereby improving the reliability of the system's backup power supply.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention has a user-specific backup power control function, which can monitor the total input and the power distribution parameters and metering functions of each user in real time, and perform differentiated backup power according to different user needs; the equipment has a timed shutdown function, and controls the power supply of communication equipment in a time period set according to 5G service requirements to reduce unnecessary energy loss. Two Hall sensors monitor the input voltage signal, current signal, and power consumption parameters of each user to realize the metering function. The timing parameters are set through the operation and maintenance platform or the human-computer interaction module and sent to the single-chip microcomputer through the communication module. The single-chip microcomputer controls the execution unit to perform backup power control.

[0022] 2. The equipment has a backup power control function. When the city power is out, it provides three backup power modes: time backup, voltage backup, and power backup. It can set the backup power parameters according to customer needs, and automatically disconnect the communication equipment after the backup power demand is met, so as to avoid excessive discharge of the battery, effectively protect the battery, and extend the service life of the battery. The backup power duration is set through the operation and maintenance platform or the human-computer interaction module, and the backup power duration is sent to the single-chip microcomputer through the communication module. The single-chip microcomputer controls the execution unit to control the backup power and realizes the backup power duration. The backup power voltage limit is set through the operation and maintenance platform or the human-computer interaction module, and the backup power voltage limit is sent to the single-chip microcomputer through the communication module. The single-chip microcomputer controls the execution unit to control the backup power. When the power supply voltage is greater than the backup power voltage limit, the backup power line is connected to perform backup power. When the power supply voltage is less than the backup power voltage limit, the execution unit is disconnected and the backup power is stopped to realize the voltage backup function. The backup power limit is set through the operation and maintenance platform or the human-computer interaction module and sent to the single-chip microcomputer through the communication module. The single-chip microcomputer controls the execution unit to perform backup power control. When the power reaches the backup power limit, the single-chip microcomputer controls the execution unit to disconnect and stop the backup power, thereby realizing the power backup function.

[0023] 3. The device has overvoltage and undervoltage shutdown protection functions. When the power supply voltage exceeds the set protection limit, it can automatically disconnect the back-end communication equipment to avoid damage to the communication equipment caused by working under abnormal voltage. When the data acquisition unit detects that the power supply voltage exceeds the protection limit, the microcontroller controls the execution unit to disconnect the backup circuit.

[0024] 4. The equipment has the function of overload and short circuit protection for each user, which can automatically shut down the overload or short circuit user to improve the reliability of the system power supply. When the data acquisition unit detects that the supply current exceeds the protection limit, the single product Aki control execution unit disconnects the supply circuit.
