Background

The power supply part of the switch power supply cabinet mainly comprises a switch power supply, a storage battery pack and the like, wherein the switch power supply converts an input 220V alternating current power supply into a 48V direct current power supply to float and charge the storage battery pack and supply power to the communication system. The storage battery can normally supply power to the communication system within a period of time when the mains supply is powered off, and communication interruption caused by power failure is avoided.

The premise that the base station normally works is that a switch power supply cabinet of the base station of the communication system supplies power to the communication system normally. The power supply of the communication system base station mainly comprises an input 220V alternating current power supply, a switching power supply output power supply of a switching power supply cabinet and a standby storage battery pack power supply of the switching power supply cabinet.

The storage capacity of the standby storage battery is deteriorated, so that the storage battery pack cannot be fully charged, and the communication system loses power and does not work any more in a short time after the mains supply is powered off, thereby affecting the normal operation of the communication system. The defects are more obvious because the whole equipment is influenced by factors such as component aging and the like after being used for a long time, and the probability of influencing the normal operation of a communication system is higher when the working performance of a power supply part is reduced or a fault occurs when a manager does not manage the base station of the field communication system because the management is inconvenient.

As shown in fig. 2, in the ac detection circuit: after a 220V alternating current power supply enters a primary winding of a transformer T, a 5V alternating current power supply output by a secondary winding of the transformer T enters two ends 1 and 2 of a power supply input end of a rectifier bridge stack A2, the rectifier bridge stack A2 outputs a stable direct current power supply by 3 and 4 pins under the action of an internal circuit of the rectifier bridge stack A2, the other ends of a resistor R3 and a R4 (an electrolytic capacitor C filters the output direct current power supply), the direct current power supply enters two control power supply input ends of a relay J1 after voltage reduction and current limitation by a resistor R3 and a resistor R4, under the practical condition, when the voltage of the 220V alternating current power supply is unstable and fluctuates, the direct current power supply voltage input to the two control power supply input ends of the relay J1 can dynamically change (the voltage is high and the voltage enters the other ends of the resistor R3 and the R4, the voltage is low and the voltage enters the resistor R3 and the voltage at the other ends of the R4), the time controller A4 can output 3 seconds of power supply at intervals of 15 seconds after being electrified to enter two ends of the power supply input of the relay J1, then the relay J1 is electrified to pull in two control power supply input ends and two normally open contact ends of the relay J1 to be closed, and because the two normally open contact ends of the relay J1 are connected with the signal input ends 3 and 4 pins of the singlechip module A10, the direct-current power supply signals after being subjected to voltage reduction and current limitation by the resistors R3 and R4 can enter the signal input ends 3 and 4 pins of the singlechip module A10 in the power supply time of outputting 3 seconds at intervals of 15 seconds by the time controller A4, and the direct-current power supply signals after being subjected to voltage reduction and current limitation by the resistors R3 and R4 can enter the signal input ends 3 and 4 pins of the singlechip module A10. 48V detection circuit: in actual operation, the power output by the pins 3 and 4 of the switching power supply a1 enters the other ends of the resistors R1 and R2, and the dc power enters the two control power input ends of the relay J2 after being reduced in voltage and limited in current by the resistors R1 and R2, under actual conditions, when the voltage of the power output by the pins 3 and 4 is unstable due to a plurality of reasons such as long service time of the switching power supply a1 or poor performance of components, the dc power voltage input to the two control power input ends of the relay J2 dynamically changes (the voltage is high and enters the resistor R1, the voltage at the other end of R2 is high and the voltage is low and enters the resistor R1 and the voltage at the other end of R2), when the time controller a5 outputs power at intervals of 19 seconds after the time controller a5 is powered, the power is output to the two power input ends of the relay J2, therefore, the relay J2 is electrified to attract the two control power supply input ends and the two normally open contact ends to be closed, because the two normally open contact ends of the relay J2 are connected with the signal input ends 3 and 4 pins of the single chip module A10, the time controller A5 outputs 3 seconds of power supply time at intervals of 19 seconds, direct current power supply signals can enter the signal input ends 3 and 4 pins of the single chip module A10 after being subjected to voltage reduction and current limitation through the resistors R1 and R2, the process is continuously circulated, and the direct current power supply signals can enter the signal input ends 3 and 4 pins of the single chip module A10 after being subjected to voltage reduction and current limitation through the resistors R1 and R2 at intervals of 19 seconds. In the battery performance detection circuit: in actual work, the power output by the storage battery enters the other ends of the resistors R5 and R6, the direct current power enters the two control power input ends of the relay J3 after the voltage is reduced and limited by the resistors R5 and R6, in actual conditions, when the voltage of the power output by the storage battery is reduced due to a plurality of reasons such as long service time of the storage battery, the voltage of the direct current power input to the two control power input ends of the relay J3 changes (the voltage of the other ends of the resistors R5 and R6 is high, the voltage of the other ends of the resistors R5 and R6 is low), when the time controller A6 works, under the power output time of the power output ends 3 and 4 pins set by technical personnel, the time controller A6 outputs 3 seconds every 23 seconds after being electrified and enters the two power input ends of the relays J3 and J4, then the relays J3 and J4 are electrified and attracted, and the two control power input ends and two normally open contacts are closed after the relay J3 is attracted, the control power input end and the normally closed contact end of the relay J4 are opened after the relay J4 is electrified and closed, and because the control power input end of the relay J4 is connected with the anode of the first storage battery G1 of the storage battery pack, and the normally closed contact end of the relay J4 is connected with the 3-pin anode power output end of the switch power supply A1, the power output by the 3-pin anode power output end of the switch power supply A1 cannot enter the storage battery pack G at the moment, so that the power output by the switch power supply A1 cannot enter the storage battery pack, and further interference is brought to the voltage performance detection of the storage battery pack; after two control power supply input ends and two normally open contact ends of the relay J3 are closed by electric attraction, because the two normally open contact ends of the relay J3 are connected with the signal input ends 3 and 4 pins of the single chip microcomputer module A10, therefore, the time controller A6 outputs 3 seconds of power supply time every 23 seconds, after the resistor R5 and the R6 are used for reducing voltage and limiting current, the direct current power supply signal can enter the signal input ends 3 and 4 pins of the single chip microcomputer module A10, the process is circulated continuously, and every 23 seconds, after the resistor R5 and the R6 are used for reducing voltage and limiting current, the direct current power supply signal can enter the signal input ends 3 and 4 pins of the single chip microcomputer module A10. After the single chip module A10 is powered on to work, three groups of analog power signals input at intervals in a circulating mode can be converted into digital signals under the action of an internal circuit of the single chip module A10 and are input into a signal input port of the GPRS module A11 through an RS485 data output port, and therefore the GPRS module A11 can send out 220V alternating current power signals detected by an alternating current detection circuit input at intervals in a circulating mode, power signals output by a switching power supply A1 detected by a 48V detection circuit and storage battery power signals detected by a storage battery performance detection circuit through a wireless mobile network under the action of functions of the GPRS module A11. After the GPRS module continuously and circularly sends three groups of dynamically changed data, powerful technical support is provided for a far-end manager to master various on-site power supply data in real time through a mobile phone or a computer by the existing mature data receiving and processing technology. The mobile phone APP and the computer application software receive the dynamically changed digital signal data uploaded by the GPRS module A11, and then the data high-low signals are displayed on a screen through a waveform diagram or a numerical value (the display of the data high-low signals on the screen through the waveform diagram or the numerical value is the existing application and the wide technology); the high or large value of the waveform diagram represents that the 220V alternating current power supply signal detected by the received alternating current detection circuit is large and the alternating current 220V input power supply is high, and the low or small value of the waveform diagram represents that the 220V alternating current power supply signal detected by the received alternating current detection circuit is small and the alternating current 220V input power supply is low; a high waveform diagram or a large value represents that the power supply signal output by the switching power supply A1 detected by the received 48V detection circuit is large and the power supply output by the switching power supply A1 is high, and a low waveform diagram or a small value represents that the power supply signal output by the switching power supply A1 detected by the received 48V detection circuit is small and the power supply output by the switching power supply A1 is low; the high or large value of the waveform diagram represents that the received storage battery pack power supply signal detected by the storage battery performance detection circuit is large, and the output power of the storage battery pack is high, and the low or small value of the waveform diagram represents that the received storage battery pack power supply signal detected by the storage battery performance detection circuit is small, and the output power of the storage battery pack is low. Because the 220V AC power supply signal detected by the AC detection circuit, the power supply signal output by the switching power supply A1 detected by the 48V detection circuit and the storage battery pack power supply signal detected by the storage battery performance detection circuit are sent in a circulating manner, a manager can specifically judge which of the 220V AC power supply signal detected by the AC detection circuit, the power supply signal output by the switching power supply A1 detected by the 48V detection circuit and the storage battery pack power supply signal detected by the storage battery performance detection circuit is received in each time period according to the time interval difference of the three groups of power supply signals, for example, after a certain signal output end is output, a similar waveform diagram or numerical value display exists after 15 seconds, which represents that the 220V AC power supply signal detected by the AC detection circuit is displayed at the moment, and then the power supply signal output by the switching power supply A1 detected by the 48V detection circuit is subsequently detected, And the storage battery performance detection circuit detects a storage battery power supply signal. In practical situations, the normal signal voltage input to the single chip module a10 through the resistors R3 and R4 is about 1V, the normal signal voltage input to the single chip module a10 through the resistors R1 and R2 is about 2V, and the normal signal voltage input to the single chip module a10 through the resistors R5 and R6 is about 3V, so that various signal waveform diagrams and values can be different, and a manager can more effectively judge whether the input voltage of the ac power supply is normal, whether the output power of the switching power supply a1 is normal, and whether the output power of the storage battery pack is normal according to various data waveform diagrams and values grasped in normal management, after the waveform diagrams and the values are obviously changed, the manager can judge whether the input voltage of the ac power supply is normal, whether the output power of the switching power supply a1 is normal, and whether the output power of the storage battery pack is normal according to the magnitude of the waveform diagrams and the output voltage of the. In practical use, after a remote manager receives partial data of the power supply of the switch power supply cabinet body for the remote communication system, if the data is too high or too low and the communication system is likely to have a fault, the power supply of the communication system can be disconnected through the remote control circuit A8 at the first time to prevent the fault from being expanded; the manager sends a first path of wireless closing control signal through a mobile phone APP or a PC application, after a remote control switch finished product A8 receives a control instruction, a first path of control power supply output end X outputs power to enter a relay J5 positive power supply input end, a relay J5 is electrified to attract the control power supply input end and a normally closed contact end to be opened, and because the relay J5 normally closed contact end and a communication system A9 positive power supply input end of a communication system base station are connected through a lead, the communication system A9 loses power and does not work any more at the moment, and the power supply abnormal communication system A9 is prevented from being damaged; when a manager sends a first open-circuit control signal through a mobile phone APP or a PC application, a finished remote control switch product A8 receives a control instruction, a first path of control power output end X no longer outputs power to enter a positive power input end of a relay J5, the control power input end of the relay J5 loses power and a normally closed contact end are closed, and because the normally closed contact end of the relay J5 and the positive power input end of a communication system A9 of a communication system base station are connected through a wire, the communication system A9 can be powered on again to work at the moment, and the purpose of remote control is achieved.
