The implementation of the present invention will be described in detail below with reference to specific embodiments.
Referring to fig. 1 and 2, a preferred embodiment of the present invention is provided.
In a first aspect, the present invention provides a method for monitoring an intelligent power distribution cabinet, including:
s1: receiving a power distribution cabinet unlocking code, checking the power distribution cabinet unlocking code, and if the checking is successful, enabling the power distribution cabinet to enter a first unlocking state;
s2: when the power distribution cabinet enters the first unlocking state, starting a power distribution simulation platform of the power distribution cabinet, acquiring data of an existing wiring scheme on the power distribution cabinet, and simulating the data of the existing wiring scheme based on the power distribution simulation platform to construct an existing power distribution model;
s3: receiving a preset wiring scheme, carrying out data simulation on the preset wiring scheme based on the power distribution simulation platform, constructing a preset power distribution model on the basis of the existing power distribution model, carrying out data analysis on the preset power distribution model to judge the rationality of the preset wiring scheme, and if the judgment result meets a preset standard, enabling the power distribution cabinet to enter a second unlocking state;
s4: and after the power distribution cabinet enters the second unlocking state, data acquisition is carried out on the wiring change condition of the power distribution cabinet, the wiring change condition is monitored according to the preset wiring scheme, if the monitoring result accords with the preset wiring scheme, the second unlocking state is exited, and if the monitoring result does not accord with the preset wiring scheme, early warning information is sent.
Specifically, the power distribution cabinet is provided with a cabinet door, in one embodiment of the invention, an unlocking device is arranged on the cabinet door, the unlocking device locks the cabinet door, and the unlocking device can unlock only by inputting an unlocking code through the unlocking device and checking the unlocking code through the power distribution cabinet, so that the cabinet door is in a first unlocking state.
It should be noted that in the above unlocking process, the number of unlocking codes that can be checked is at least one, and each unlocking code corresponds to a worker, that is, different workers make the power distribution cabinet enter the first unlocking state through their own unlocking codes, the power distribution cabinet receives the unlocking codes and records the unlocking codes, so that the workers operating the power distribution cabinet can be traced back according to the records, and the responsibility tracing of the operation of the power distribution cabinet is realized.
More specifically, the switch board entering the first unlocked state represents the door of the switch board being opened, and a worker may perform subsequent operations on the switch board.
More specifically, after the power distribution cabinet enters the first unlocking state, the module configured on the power distribution cabinet will be automatically started to run the power distribution simulation platform loaded on the simulation device, and the power distribution simulation platform simulates a wiring scheme of the power distribution cabinet to judge the rationality of the wiring scheme, so that the wiring risk caused by directly wiring the power distribution cabinet is avoided.
More specifically, before a worker operates the power distribution cabinet, the power distribution simulation platform needs to simulate the existing wiring scheme in advance to construct an existing power distribution model, simulate the preset wiring scheme on the basis of the existing power distribution model, and construct the preset power distribution model on the basis of the existing power distribution model.
It can be understood that the existing wiring scheme is the wiring scheme which the power distribution cabinet already has, and the preset wiring scheme is the wiring scheme which is prepared for carrying out the power distribution cabinet, and the wiring scheme is based on the outgoing cable of the power distribution cabinet and is electrically connected with an external device to be powered, so that the connection scheme for supplying power to the power distribution cabinet is realized.
It should be noted that the simulation process is divided into two segments because the preset wiring scheme requires the active input of a worker on the simulation device, whereas the existing wiring scheme can be obtained by data acquisition of wiring on the power distribution cabinet, and the simulation of the existing wiring scheme is based on the simulation of the existing information and the history information, and the simulation of the preset wiring scheme is based on the estimated information, that is, in the simulation, the simulation of the existing wiring scheme is relatively fixed, and the preset wiring scheme is changed, so that the simulation needs to be divided into two segments.
More specifically, after the power distribution simulation platform constructs a preset power distribution model of the preset wiring scheme, data analysis is performed on the preset power distribution model to judge the rationality of the preset wiring scheme, and if the judging result is compounded with the preset standard, the power distribution cabinet is enabled to enter a second unlocking state.
More specifically, when the power distribution cabinet is in the first unlocked state, it represents a rationality prediction of the not-completed preset wiring scheme, at which time the power distribution cabinet is not allowed to be directly operated by the staff, because at this time there is a risk of unreasonable wiring scheme.
More specifically, when the power distribution cabinet enters the second unlocking state from the first unlocking state, data acquisition is performed on the wiring change condition of the power distribution cabinet, and the wiring change condition of the power distribution cabinet is monitored according to a preset wiring scheme, and it is understood that the wiring change condition represents wiring change on the power distribution cabinet, that is, change of the electrical connection relation between the external device and the power distribution cabinet.
More specifically, through the monitoring of the change condition of the connection wire, the fault of the working personnel in the wiring process can be prevented, the working personnel can be prevented from wiring according to the preset wiring scheme, if the monitoring result accords with the preset wiring scheme, the second unlocking state is exited, the first unlocking state is restored, the wiring change of the power distribution cabinet is ended, and if the monitoring result does not accord with the preset wiring scheme, early warning information is sent to prompt the working personnel to wire according to the preset wiring scheme.
The invention provides a monitoring method of an intelligent power distribution cabinet, which has the following beneficial effects:
1. according to the invention, the simulation is performed according to the existing wiring scheme, the existing power distribution model is obtained, the simulation is performed according to the preset wiring scheme, the preset power distribution model is obtained, and the data analysis is performed on the preset power distribution model to judge whether the preset wiring scheme is reasonable, so that whether the preset wiring scheme meets the safety standard or not can be judged before the preset wiring scheme is implemented, and the problem that the risk after the wiring scheme is changed is difficult to predict when the wiring scheme of the power distribution cabinet is changed in the prior art is solved.
2. According to the invention, before a preset wiring scheme is implemented, two working procedures are required to be simulated through the unlocking code and the scheme, so that wiring operation is performed on the power distribution cabinet through the first unlocking state and the second unlocking state, and when the unlocking code is input, the identity information of a worker can be obtained, so that the worker is recorded, and responsibility of the worker can be traced.
Preferably, when the power distribution cabinet does not enter the first unlocking state, the cabinet door of the power distribution cabinet is in a closed state, and when the power distribution cabinet enters the first unlocking state, the cabinet door of the power distribution cabinet is in an open state.
Specifically, the power distribution cabinet is provided with a cabinet door, the cabinet door is used for sealing and protecting the power distribution cabinet, and the opening and closing of the cabinet door are determined by whether the cabinet door is in a first unlocking state or not.
More specifically, when the switch board did not receive the unblock code, when the switch board did not get into first unblock state, the cabinet door of switch board was the closed state, and the cabinet door of switch board can't open this moment, if someone disassembles the cabinet door through violent means, will send alarm information.
More specifically, when the power distribution cabinet receives the unlocking code and passes the verification of the unlocking code, the power distribution cabinet enters a first unlocking state, and at the moment, the cabinet door of the power distribution cabinet can be opened.
Preferably, the step of collecting data of an existing wiring scheme on the power distribution cabinet and performing data simulation on the existing wiring scheme based on the power distribution simulation platform to construct an existing power distribution model includes:
s21: data acquisition is carried out on the existing wiring scheme on the power distribution cabinet so as to acquire connection data and power supply data of all wiring on the power distribution cabinet, and a power distribution model infrastructure of the power distribution cabinet is constructed according to the connection data of all wiring;
s22: and continuously acquiring power supply data of each wiring of the power distribution cabinet based on the existing wiring scheme on the power distribution cabinet, filling the power distribution model infrastructure according to the power supply data of each wiring, and generating the existing power distribution model of the power distribution cabinet to obtain the power supply pressure condition of the power distribution cabinet at each past time point.
Specifically, after the unlocking code is input, the power distribution cabinet enters a first unlocking state, and at the moment, the power distribution cabinet enters a simulation step, and firstly, the power distribution cabinet can acquire data of the existing wiring scheme on the power distribution cabinet so as to acquire connection data of all wiring on the power distribution cabinet.
More specifically, the connection data of the wiring represents the power supply object connected with the cable on the power distribution cabinet, namely the device for receiving the power supplied by the power distribution cabinet, and it is understood that the devices have different performances, different requirements for power supply, and different power supply pressures are caused for the power distribution cabinet by the requirements, so that each power consumption device electrically connected with the power distribution cabinet can be known according to the connection data of each wiring, and thus the power distribution model infrastructure of the power distribution cabinet is formed.
More specifically, based on the existing wiring scheme on the power distribution cabinet, the power supply data of each wiring of the power distribution cabinet is continuously collected, the power supply data of each wiring represents the power supply condition of the wiring in different time periods, that is, the power supply data is calculated according to the working state of the electric device according to the historical data of the wiring, and the power supply pressure of the electric device on the power distribution cabinet is different according to the working state of the electric device, so that the power supply pressure of the power distribution cabinet in different time periods can be obtained by combining the power supply data of the wiring, that is, the power distribution model infrastructure is filled according to the power supply data of each wiring, and the existing power distribution model of the power distribution cabinet is generated, so that the power supply pressure condition of the power distribution cabinet in various past time points is obtained.
It should be noted that, the power distribution model infrastructure is an existing power distribution model infrastructure, the existing power distribution model describes the power supply pressure condition of the existing wiring scheme at each time point, in order to achieve the description, two parts are needed to be completed, the first part is to collect data of the electric devices connected by each wiring in the existing wiring scheme to construct the connection relationship between the power distribution cabinet and each electric device, the power distribution model infrastructure is the power distribution model infrastructure, and the second part is to fill the power supply data based on the power distribution model infrastructure to obtain the power supply pressure condition of the power distribution cabinet at each time point in the past.
It can be understood that each electric device consumes electric energy during operation, and different power supply data can be generated at the power distribution cabinet by different degrees of electric energy consumption, and it is easy to see that the power supply data corresponds to each electric device one by one, and the power distribution model infrastructure describes the connection relationship between each electric device and the power distribution cabinet, that is, the power supply data can be given to each electric device in the power distribution model infrastructure, that is, the power distribution model infrastructure is filled according to the power supply data in the step.
Preferably, the step of receiving a preset wiring scheme, performing data simulation on the preset wiring scheme based on the power distribution simulation platform, constructing a preset power distribution model based on the existing power distribution model, and performing data analysis on the preset power distribution model to determine the rationality of the preset wiring scheme includes:
s31: receiving the preset wiring scheme to obtain power supply objects of all wiring performed on the power distribution cabinet in a preset mode;
s32: according to the power supply objects of each wiring, the maximum power supply demand data corresponding to the power supply objects are called from a database, and the maximum power supply demand data are overlapped on the existing power distribution model to obtain the preset power distribution model;
s33: and analyzing the preset power distribution model to acquire the power supply condition of the power distribution cabinet at each time point, and analyzing the power supply condition according to a safety standard to judge the rationality of the preset wiring scheme.
Specifically, the preset wiring scheme is a wiring scheme for performing work preparation on the power distribution cabinet, and before the scheme is formally implemented, a simulation is required to be performed on a simulation device on the power distribution cabinet to judge the rationality of the preset wiring scheme, that is, the preset wiring scheme is input through the simulation device, so that the power distribution cabinet receives the preset wiring scheme.
More specifically, according to the preset wiring scheme, the power supply objects of each wiring can be obtained, the maximum power supply demand data of the corresponding power supply object is called from the database according to the power supply objects of each wiring, and the power supply objects are overlapped on the existing power distribution model according to the maximum power supply demand data, so that the preset power distribution model is obtained.
It can be understood that the above superposition is superposition of data, that is, the power supply data of each time point of each power supply object in the existing power distribution model is respectively superposed with the corresponding maximum power supply demand data.
It should be noted that the preset power distribution model is a model for simulating a preset wiring scheme, and based on the preset power distribution model, the overall power supply condition of the power distribution cabinet can be analyzed to obtain the power supply condition of the power distribution cabinet at each time point, and the power supply condition is analyzed according to the safety standard to judge the rationality of the preset wiring scheme.
It will be appreciated that the maximum power requirement of the power supply object is used in constructing the preset power distribution model in order to maximize safety considerations, so as to avoid the risk of excessive power supply pressure caused by the preset wiring scheme.
Preferably, the method further comprises:
s51: acquiring a power supply object requiring the power distribution cabinet to supply power according to the preset power distribution model;
s52: according to the power supply object, the maximum power supply demand data corresponding to the power supply object is called from a database, and the maximum power supply demand data is combined with the power supply object to generate a limit power supply target unit;
