Description

Technical Field

[0001] The invention relates to the technical field of emergency power supply, and in particular to an emergency power supply system. Background Art

[0002] The power emergency power supply system is a system that ensures that power can be continuously supplied to key equipment or systems when the main power supply is interrupted or fails. The system usually consists of a main power supply, a power supply (UPS), a battery pack, a generator, etc., and each module works together to ensure the continuity and stability of power supply. Under normal circumstances, the main power supply provides power to the equipment, and when the main power supply fails or is interrupted, the power emergency power supply system will automatically or manually switch to a backup power supply, such as a UPS system or a generator. The UPS system can quickly take over the power supply when the power is interrupted to ensure the continuous operation of the equipment; and the generator can provide long-term backup power to ensure that the equipment is not affected by power outages for a long time.

[0003] After the power supply in the building has been used for a long time, its circuit components will age, which will cause the voltage that the power supply can withstand to change. If the current voltage during emergency power supply after power failure exceeds or falls below the withstand voltage, the stability of the power supply will be affected. Therefore, a power emergency power supply system is needed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an emergency power supply system, which solves the problem that the stability of the power supply will be affected during emergency power supply due to the aging of the floor power supply and the change in voltage.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] A power emergency power supply system includes a power outage judgment module, a regional hierarchical power supply module, an allocation area judgment module, a voltage distribution module and an online supply module. The power outage judgment module is used to detect the cause of the power outage to provide a reasonable emergency power supply plan. The regional hierarchical power supply module is used to classify the power supply areas and preliminarily exclude the areas that do not need power supply. The allocation area judgment module is used to secondary exclude the areas that do not need power supply, reduce the consumption of the generator, and extend the power supply time. The voltage distribution module is electrically connected to a power outage simulation module. The power outage simulation module cooperates with the equipment status report provided by the voltage calibration module to perform power outage simulation training, and assists the voltage distribution module to quickly provide stable voltage and current supply to each power supply on the floor without temporary calculation of voltage supply. The online supply module is used to command the voltage distribution module to supply power to the unpowered saving area according to demand.

[0007] Preferably, the allocation area judgment module includes a block search unit, a block detection unit and an allocation transmission permission protocol which are electrically connected to each other. The search work of the block search unit is based on the circuit distribution map stored on each floor. The detection work of the block detection unit is realized by means of the circuit distribution map. The detection work is based on the regional power supply situation within 60 seconds before the power outage, and the allocation transmission permission protocol is activated according to the judgment result.

[0008] Preferably, the voltage calibration module includes a power status analysis unit, an output correction unit and a record table generation unit which are electrically connected to each other. The analysis work of the power status analysis unit uses the status data of the power maintenance detection on each floor, and the output correction work of the voltage and current is performed by comparing the old data with the output correction unit. The record table generation unit is used to generate the results of the output correction work of the voltage and current, and store them in a tabular form.

[0009] Preferably, the power-off simulation training module includes a power-off simulation unit and a training record storage unit which are electrically connected to each other, the simulation work of the power-off simulation unit adopts the tabular data in the output correction work of the voltage and current, the simulation work records are saved and recorded by the training record storage unit, and useless old records are eliminated.

[0010] Preferably, the online supply module includes a manual remote operation unit, an intelligent operation unit and a preset scheme judgment unit which are electrically connected to each other. The manual remote operation unit is used to remotely operate the system according to external demand to control the additional power supply to a specific area, and the intelligent operation unit judges the external demand based on the preset scheme stored in the preset scheme judgment unit to control the system to quickly perform power supply.

[0011] A power emergency power supply method, using a power emergency power supply system as claimed in any one of claims 1 to 5, comprising the following steps:

[0012] Step 1: Activate the emergency power supply system and generator when a power outage occurs;

[0013] Step 2: During the start-up of the generator, the power outage judgment module determines the cause of the power outage and generates a corresponding power supply plan;

[0014] Step 3: The regional hierarchical power supply module determines the priority of the power supply area according to the power supply plan generated in step 2, and preliminarily excludes the areas that do not need power supply;

[0015] Step 4: Use the allocation area judgment module to perform secondary area judgment, eliminate the areas that do not need power supply again, and arrange the power supply area priorities, and the priorities are arranged according to the level of emergency;

[0016] Step 5: The voltage distribution module quickly distributes the voltage and current of each area for power supply according to the power supply area priority in step 4;

[0017] Step 6: During the power supply process, when external demands are made, the online supply module responds and makes subsequent adjustments to the emergency power supply;

[0018] Step 7: When power supply is restored, shut down the emergency power supply system.

[0019] Preferably, in step one, activation of the emergency power supply system is powered by a small power source.

[0020] Preferably, the power supply schemes in step 2 are divided into two types, one of which is a non-disaster emergency power supply scheme, and the other is a disaster emergency power supply scheme. The non-disaster emergency power supply scheme gives priority to supplying power to the server placement areas, fire safety equipment areas and other areas that cannot be powered off on each floor, and the disaster emergency power supply scheme gives priority to supplying power to the fire safety passage areas, fire safety equipment areas and other areas that respond to disasters.

[0021] Preferably, the emergency power supply work in step 2 to step 5 is quickly executed according to the simulated work record stored in the power outage simulation training module, and the generation of the simulated work record includes the following steps:

[0022] S1. Maintenance personnel shall regularly inspect and maintain the power supply of each floor, detect the voltage and resistance of the power supply, and record the specific data;

[0023] S2, importing the data into the voltage calibration module, the power supply status analysis unit analyzes the recorded data, and the data correction unit generates a solution for adjusting the voltage and current output of the corresponding power supply according to the analysis results;

[0025] S4. Record and classify the entire simulation process, store it in the training record storage unit, and eliminate useless old data.

[0026] Preferably, the specific way in which the online supply module responds in step six is: the intelligent operation unit responds first, and uses the preset response measures in the preset scheme judgment unit to judge the external demand. If the judgment is passed, the emergency power supply area is adjusted according to the demand. If the judgment fails, the demand is rejected. If the outside world makes a new request, it is transferred to the manual remote operation unit for manual judgment, adjustment of the system, and allocation of the power supply area.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example:

[0039] As one aspect of this application, please see the attached Figure 1 -Attached Figure 6 The embodiment of the present invention provides an emergency power supply system, including a power outage judgment module, a regional hierarchical power supply module, an allocation area judgment module, a voltage distribution module and an online supply module. The power outage judgment module is used to detect the cause of the power outage to provide a reasonable emergency power supply plan. The regional hierarchical power supply module is used to classify the power supply area and preliminarily exclude the area that does not need power supply. The allocation area judgment module is used to secondary exclude the area that does not need power supply, reduce the consumption of the generator, and extend the power supply time. The voltage distribution module is electrically connected to the power outage simulation module. The power outage simulation module cooperates with the equipment status report provided by the voltage calibration module to perform power outage simulation training. The auxiliary voltage distribution module quickly supplies stable voltage and current to each power supply on the floor without temporarily calculating the voltage supply. The online supply module is used to command the voltage distribution module to supply power to the unpowered saving area according to demand.

[0040] The allocation area judgment module is composed of a block search unit, a block detection unit and an allocation transmission permission protocol that are electrically connected to each other. The search work of the block search unit is based on the circuit distribution map stored on each floor, and the detection work of the block detection unit is realized by means of the circuit distribution map. The detection work is based on the regional power supply situation within 60 seconds before the power outage, and the allocation transmission permission protocol is activated according to the judgment result.

[0041] The voltage calibration module is composed of a power status analysis unit, an output correction unit and a record table generation unit which are electrically connected to each other. The power status analysis unit uses the status data of the power maintenance detection on each floor for analysis, and the output correction unit performs output correction work of voltage and current by comparing with old data. The record table generation unit is used to generate the results of the output correction work of voltage and current, and store them in a table form.

[0042] The power-off simulation training module consists of a power-off simulation unit and a training record storage unit which are electrically connected to each other. The simulation work of the power-off simulation unit adopts the tabular data in the output correction work of voltage and current. The simulation work records are saved and recorded through the training record storage unit, and useless old records are eliminated.

[0043] The online supply module is composed of a manual remote operation unit, an intelligent operation unit and a preset scheme judgment unit which are electrically connected to each other. The manual remote operation unit is used to remotely operate the system to control the additional power supply to a specific area according to external demand. The intelligent operation unit judges the external demand based on the preset scheme stored in the preset scheme judgment unit to control the system to quickly perform power supply.

[0044] Based on the above-mentioned power emergency power supply system, as another aspect of the present application, a power emergency power supply method, using a power emergency power supply system according to any one of claims 1 to 5, comprises the following steps:

[0045] Step 1: Activate the emergency power supply system and generator when a power outage occurs. The emergency power supply system is activated by a small power source;

[0046] Step 2: During the start-up of the generator, the power outage judgment module is used to determine the cause of the power outage and generate a corresponding power supply plan. There are two types of power supply plans, one of which is a non-disaster emergency power supply plan and the other is a disaster emergency power supply plan. The non-disaster emergency power supply plan gives priority to the server placement area, fire safety equipment area and other areas that cannot be powered off on each floor. The disaster emergency power supply plan gives priority to the fire safety passage area, fire safety equipment area and other areas that respond to disasters.

[0047] Step 3: The regional hierarchical power supply module determines the priority of the power supply area through the power supply plan generated in step 2, and preliminarily excludes the areas that do not need power supply. The areas related to safety facilities are classified as the highest level to ensure safety after power failure;

[0048] Step 4: Use the allocation area judgment module to perform secondary area judgment, eliminate the areas that do not need power supply again, and arrange the power supply area priority. The priority is arranged according to the emergency level. The elimination range is determined based on the regional power supply situation within 60 seconds before the power outage. The allocation and transmission license agreement is activated according to the judgment result. If it is determined that the area is in use before the power outage, emergency power supply will be provided to the area. If it is determined that there is no power consumption record before the power outage, emergency power supply will not be provided to the area.

[0049] Step 5: The voltage distribution module quickly distributes the voltage and current of each area for power supply according to the power supply area priority in step 4;

[0050] Step 6: During the power supply process, when external demands are made, the online supply module responds and makes subsequent adjustments to the emergency power supply. The specific methods are as follows:

[0051] The intelligent operation unit will respond first and use the preset response measures in the preset solution judgment unit to judge the external demand. If the judgment is passed, the emergency power supply area will be adjusted according to the demand. If the judgment fails, the demand will be rejected. If the outside world makes a new request, it will be transferred to the manual remote operation unit for manual judgment, adjustment of the system, and allocation of the power supply area.

[0052] Step 7: When power supply is restored, shut down the emergency power supply system.

[0053] After the power supply in the floor has been used for a long time, its circuit accessories will age, which will cause the voltage that the power supply can withstand to change. If the current voltage during emergency power supply exceeds or falls below the withstand voltage after power failure, the stability of the power supply will be affected. The emergency power supply work in steps 2 to 5 is quickly executed according to the simulation work records stored in the power failure simulation training module. The generation of simulation work records includes the following steps:

[0054] S1. Maintenance personnel shall regularly inspect and maintain the power supply of each floor, detect the voltage and resistance of the power supply, and record the specific data;

[0055] S2, importing the data into the voltage calibration module, the power supply status analysis unit analyzes the recorded data, and the data correction unit generates a solution for adjusting the voltage and current output of the corresponding power supply according to the analysis results;

[0056] S3, organizing the scheme generated in S2 into a table, inputting it into the power outage simulation unit, and using the data in the table to assist in simulating the power supply work of each area in each power outage emergency event;

[0057] S4. Record and classify the entire simulation process, store it in the training record storage unit, and eliminate useless old data.

[0058] The above method is used to simulate the power transmission of each floor in advance to adapt to the voltage that the power supply can withstand after aging. In this way, during the emergency power supply process, the power supply can be quickly and stably transmitted with appropriate voltage and current without temporary detection and calculation, thereby improving the stability of power supply.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
