Referring to fig. 1 to 3, an embodiment of the present application provides a power distribution control system including a management center 200 and a power distribution rack 100, the power distribution rack 100 including a box 101 and a power transformation control device 103 disposed in the box 101. The power distribution rack 100 further comprises an intelligent environment fusion microsensor unit 105 disposed within the enclosure 101;
the intelligent environment fusion microsensor unit 105 is in communication connection with the management center 200, and is configured to collect environmental information in the box 101, determine whether a first dangerous situation occurs based on the environmental information, and control the working state of the power transformation control device 103;
the management center 200 is configured to execute a power distribution scheme in a specified area based on the working state of the power distribution rack 100;
Wherein, when the intelligent environmental fusion microsensor unit 105 determines that the first dangerous case occurs in the power distribution rack 100 based on the collected first environmental information, alarm information is sent to the management center 200, and second environmental information collected after the first environmental information is sent to the management center 200;
the management center 200 determines whether a second dangerous case occurs based on the second environmental information; if the second dangerous case is judged to occur, sending dangerous case determining information to the intelligent environment fusion microsensor unit 105, and adjusting the power distribution scheme of the designated area;
the intelligent environment fusion microsensor unit 105 controls the operation state of the power transformation control device 103 based on the dangerous situation determination information.
The intelligent environmental fusion microsensor unit 105 is a sensing device that fuses a plurality of different environmental collection modules, for example, an oxygen detection module, a smoke detection module, a water immersion detection module, and the like, and performs dangerous situation assessment locally through various collected environmental information, when the first dangerous situation occurs in the power distribution rack 100, sends alarm information to the management center 200, and sends second environmental information collected after the first environmental information to the management center 200, so that the management center 200 determines whether the second dangerous situation occurs in the power distribution rack 100 based on the second environmental information, if so, the management center 200 schedules workers for maintenance, and the like, adjusts a power distribution scheme of a corresponding area, and sends dangerous situation determination information to the intelligent environmental fusion microsensor unit 105, so that the intelligent environmental fusion microsensor unit 105 controls the working state of the power transformation control device 103. Because the first dangerous case is obtained by self-evaluation of the intelligent environment fusion microsensor unit 105, when the intelligent environment fusion microsensor unit 105 does not obtain the first dangerous case, the environment information at the power distribution rack 100 is not required to be sent to the management center 200 in real time for carrying out dangerous case evaluation, so that network transmission resources are saved, meanwhile, the management center 200 is not required to calculate whether the wiring rack is in dangerous case in real time, and the demand on calculation force is greatly reduced.
The management center 200 is a background server for remotely managing all the power distribution racks 100 in a specific area, and in the prior art, the management center 200 acquires environmental information fed back by one end of the power distribution rack 100 to analyze whether a dangerous situation occurs at one end of the power distribution rack 100, and because there are numerous power distribution racks 100 in the area, it is necessary to acquire data in real time to analyze, so that the management center 200 needs to have a strong calculation power. According to the management center 200, only after the intelligent environment is integrated with the microsensor unit 105 to upload the first dangerous case and the second environment information, the management center 200 calculates whether the second dangerous case happens once, and does not need to perform dangerous case assessment in real time, so that the calculation power requirement of the management center 200 is greatly saved. Further, when the intelligent environment fusion microsensor unit 105 sends alarm information to the management center 200, the alarm information carries current environmental information (second environmental information acquired after the first environmental information), and the management center 200 can evaluate whether the corresponding power distribution rack 100 generates the second dangerous case again based on the current environmental information, if so, send dangerous case determining information to the intelligent environment fusion microsensor unit 105, and adjust the power distribution scheme in the designated area; the intelligent environment fusion microsensor unit 105 controls the operation state of the power transformation control device 103 based on the dangerous situation determination information. The first dangerous case and the second dangerous case may be the same dangerous case or different dangerous cases, and in either case, the dangerous case of the corresponding power distribution rack 100 can be basically determined, and timely maintenance is required.
The above power distribution scheme refers to a power distribution scheme of the management center 200 for each sub-area in the corresponding designated area, for example, the designated area includes a plurality of sub-areas, each sub-area is provided with a power distribution rack 100, and the power distribution rack 100 mainly manages the power supply condition of the corresponding sub-area, of course, each power distribution rack 100 is also connected with the power supply network of the adjacent sub-area, when the power distribution racks 100 of each sub-area work normally, each sub-area is not interfered with each other, but when the power distribution rack 100 of a certain sub-area has a dangerous condition and stops working, the management center 200 resets the overall power distribution scheme, for example, according to the power consumption condition of the sub-area of the power distribution rack 100 having the dangerous condition and the power consumption condition of the adjacent sub-area, the power distribution rack 100 of the adjacent area is controlled to supply power to the power supply network of the sub-area of the power distribution rack 100 having the dangerous condition. Further, according to the electricity consumption conditions of a plurality of adjacent areas of the subarea of the power distribution rack 100 where the dangerous situation occurs, one or more adjacent subareas can be selected to distribute power to the subarea of the power distribution rack 100 where the dangerous situation occurs, so as to realize balanced power distribution as much as possible, and prevent the normal power distribution of the subarea from being affected for supporting the power distribution of the subarea of the power distribution rack 100 where the dangerous situation occurs.
The power transformation control device 103 is a power distribution device in the power distribution rack 100, and may include various power distribution and/or safety control devices in the prior art. The operation states of the power transformation control device 103 generally include all the stop operation, part of the stop operation, all the normal operation, and the like. The box 101, the box door 102 and the transformation control device 103 may be any of those in the prior art, and will not be described herein.
The above method for determining whether the power distribution rack 100 is in danger based on the environmental information includes various methods, such as evaluating whether fire occurs through the information collected by the smoke detection module, whether flooding occurs through the information collected by the water logging detection module, etc.
Referring to fig. 2, in one embodiment, after the step of determining whether the second dangerous case occurs based on the environmental information, the management center 200 further includes:
if the second dangerous situation is determined to occur, the management center 200 sends a to-be-maintained command of the power distribution rack 100 and first identity tag information of a maintainer to the intelligent environment fusion microsensor unit 105, and sends the first identity tag information to a first mobile terminal 300 corresponding to the maintainer;
The first mobile terminal 300 broadcasts the broadcast information carrying the first identity tag information in a near-field wireless mode, and when the intelligent environment fusion microsensor unit 105 receives the first identity tag information transmitted by the first mobile terminal 300, the box door 102 on the box 101 is controlled to be opened;
when the door 102 is opened, the intelligent environment fusion micro-sensing unit 105 controls the door 102 to be closed when the first identity tag information transmitted by the first mobile terminal 300 is not received for a specified duration.
The first identity tag information includes first location information of the power distribution rack 100 and information of the dangerous case, where the first location information enables the first mobile terminal 300 to know the location of the power distribution rack 100 where the dangerous case occurs. The information of the dangerous case may enable the management center 200 to know the type of the dangerous case occurring in the power distribution rack 100, such as a fire or water immersion, and when the first identity tag information is sent to the first mobile terminal 300, a maintenance tool or the like corresponding to the type of the dangerous case that needs to be carried is also sent. Further, when the first mobile terminal 300 is selected, the first mobile terminal 300 corresponding to the worker adapting to the dangerous case type may be selected.

When the first mobile terminal 300 receives the first identity tag information, the corresponding staff member will know that the maintenance task is received, and further go to the distribution rack 100 where the dangerous situation occurs (the management center 200 will inform the first mobile terminal 300 of the location information of the distribution rack 100). The first mobile terminal 300 continuously performs near-field wireless broadcasting or performs near-field wireless broadcasting after entering a designated location area to carry the broadcasting information of the first identity tag information, so that the intelligent environment fusion microsensor unit 105 can receive the broadcasting information, when the first identity tag information received by the intelligent environment fusion microsensor unit 105 is consistent with the first identity tag information sent by the management center 200, a worker who performs maintenance before is determined to be a professional, the box door 102 is automatically opened, or the box door 102 is not opened, so that danger of non-professional maintenance can be prevented, the door can be automatically opened, the door opening step of the worker is reduced, and the maintenance efficiency is improved. When the door 102 is opened, the intelligent environment fusion microsensor unit 105 does not receive the first identity tag information transmitted by the first mobile terminal 300 for a specified period of time (e.g., 5 minutes, 10 minutes, etc.), which indicates that the first mobile terminal 300 leaves the power distribution rack 100, i.e., the corresponding staff leaves, and at this time, the door 102 is controlled to close, so as to prevent rainwater, animals, etc. from entering the box 101 through the door 102 and causing dangerous situations. The broadcasting by the near-field wireless method generally includes broadcasting by wireless methods such as bluetooth communication and WiFi communication, and bluetooth with low power consumption is preferable.
In a specific embodiment, the first identity tag information includes unique identification information and first location information; when the intelligent environment fusion microsensor unit 105 receives the first identity tag information transmitted by the first mobile terminal 300, it controls the door 102 on the box 101 to open, including:

judging whether the identification information is consistent with the unique identification information or not, and judging whether the position information is consistent with the first position information or not;
if the identity tag information is consistent with the first identity tag information transmitted by the first mobile terminal 300, the identity tag information received by the intelligent environment fusion microsensor unit 105 is judged to be the first identity tag information, and the door 102 is controlled to be opened.
As described above, the first identity tag information includes not only the unique identification information but also the first location information, after receiving the identity tag information, the intelligent environment fusion microsensor unit 105 analyzes the corresponding identification information and location information, and if the identification information and the location information are respectively consistent with the unique identification information and the first location information in the first identity tag information, it indicates that the current mobile terminal is the first mobile terminal 300, and can actively open the door 102. In the case that the dual conditions are met, the present embodiment controls the door 102 to open, preventing the risk of the door 102 being opened by mistake.

The specific model can be determined according to actual conditions, for example, whether dangerous situations occur or not is judged by using an end-to-end (a plurality of parameters are input into a preset neural network model to calculate to obtain an evaluation result), a singlechip with strong calculation capability is selected, if dangerous situations are judged by directly comparing environment information with a threshold value (for example, when smoke information is larger than a set threshold value, fire is judged to occur), a singlechip with weak calculation capability is selected, and the like. And a broadcast receiver connected with the singlechip and the like can be arranged in the detection box to receive the broadcast of the mobile terminal, and the analysis ratio is equal through the singlechip).
