All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, for a large-scale production and manufacturing factory, the power consumption is often large, so if the power consumption is increased a little, the power consumption is not easy to be determined to be abnormal, but once an accident occurs, a great loss is caused.
Based on this, the power distribution monitoring terminal provided by the embodiment of the invention can conveniently know the power consumption situation through the power distribution amount and the power consumption detected by the power distribution monitoring terminal, and can ensure the power safety and avoid causing serious property loss when monitoring suspected faults.
For the convenience of understanding the present embodiment, a detailed description will be given to a power distribution monitoring terminal disclosed in the present embodiment.
It should be noted that the power distribution monitoring terminal includes an intelligent terminal, and may be disposed inside a factory. The specific shape and installation mode do not affect the implementation of the embodiment of the invention, and can be set according to the actual conditions of a factory.
Fig. 1 is a schematic structural diagram of a power distribution monitoring terminal according to an embodiment of the present invention.
Referring to fig. 1, the power distribution monitoring terminal includes an acquisition module 10, a control module 20 and an execution module 30;
the acquisition module 10 is connected with the control module 20 and used for acquiring the acquisition state of the current distribution line, comparing the acquisition state of the current distribution line with preset standard parameters, acquiring the transmission power of the distribution line and the consumption power of electric equipment in a factory under the condition that the comparison result meets the requirement, and transmitting the transmission power and the consumption power to the control module based on a network layer communication protocol, if the comparison result does not meet the requirement, connecting the standby distribution line, wherein the preset standard parameters are changed in real time according to the type and the quantity of the electric equipment in the factory, different types of electric equipment have different preset standard parameters, different quantities of the same type of electric equipment also have different preset standard parameters, and the acquisition state comprises a current state, a residual current state, a voltage value and a voltage value, A temperature state and a power quality state, the delivered power and the consumed power;
a control module 20 connected to the execution module 30, for inputting the transmission power and the consumption power into a calculation model to obtain a corresponding relationship between the standard power and the consumption power carrying consumption source tag, and a power relationship between the transmission power and the consumption power, and judging whether the corresponding relation and the electric quantity relation meet a threshold relation range, if the electric quantity relation does not meet the threshold relation range, sending a first control signal to the execution module, if the corresponding relation is not satisfied, sending a second control signal to the execution module, wherein the calculation model is built based on historical transmission electric quantity, historical consumption electric quantity and equipment abnormal condition, the consumption electric quantity carries a consumption source label, the consumption sources comprise different types and different quantities of electric equipment in the factory, and the standard electric quantity is an electric quantity value consumed by each consumption source;
and the execution module 30 is configured to execute a corresponding power-off operation according to the first control signal, and perform power-off maintenance on the consumption sources that do not meet the requirements in the corresponding relationship according to the second control signal.
In a preferred embodiment of practical application, the collection state of the distribution line is monitored, so that the collection module 10 obtains relatively accurate transmission electric quantity, collects electric consumption electric quantity of each type and each number of electric devices in a factory, and determines whether the corresponding relation and the electric quantity relation satisfy the threshold relation range through the control module 20 for the electric quantity relation between the two electric devices and the electric consumption corresponding relation between the factory electric devices according to different numbers and different types, thereby performing electric monitoring of a large-scale factory.
Here, the calculation model calculates a correspondence relationship between the consumption values of the consumption source tags in the standard electric power and the consumption electric power set in advance by inputting the transmission electric power and the consumption electric power into the calculation model, and calculates an electric power relationship based on the total value of the transmission electric power and the consumption electric power.
The standard electric quantity is a standard consumption value of electric quantity corresponding to each consumption source, the consumption sources can be set according to actual monitoring requirements, if the monitoring is strict, namely small difference occurs, abnormal conditions are calculated, the consumption sources need to be finely classified, and the standard electric quantity of B equipment in an A factory at a specific time, the standard electric quantity of C equipment at a specific time and the like; if it is necessary to ensure that there is no frequent stopping brake condition in the monitoring process and avoid interruption of the monitoring process due to frequent braking, the consumption sources need to be classified and refined slightly roughly to avoid misoperation, such as standard electric quantity of a factory a at a specific time, standard electric quantity of a factory B at a specific time, and the like.
As an alternative embodiment, the standard electric quantity and the consumed electric quantity carrying the consumption source tag are related by a standard electric quantity value and an actual consumed electric quantity value corresponding to each consumption source, for example, the consumption source is B equipment of a plant-the actual consumed electric quantity is C-the standard electric quantity is D; the electric quantity relation between the transmission electric quantity and the consumption electric quantity is the comparison condition of the total electric quantity value E of the transmission electric quantity and the actual total consumption electric quantity F, and the magnitude between E and F. If the difference between the transmission electric quantity and the actual consumed electric quantity exceeds a threshold range, if the transmission electric quantity is too low, the actual consumed electric quantity is too high, the transmission electric quantity is too high, the actual consumed electric quantity is too low and the like, the situation that the threshold range is not met exists, at the moment, a first control signal is sent, the engineering side equipment is controlled to be powered off, and renovation is carried out; if the difference between the transmission electric quantity and the actual consumed electric quantity meets the threshold range, and the difference between the consumed electric quantity corresponding to each consumption source and the standard electric quantity does not meet the corresponding threshold range, if the consumed electric quantity of the equipment B of the plant A is higher or lower than the standard electric quantity, a second control signal is sent out to control the equipment B of the plant A to stop working, maintaining or refurbishing.
It is understood that the acquisition state of the distribution line may be acquired by a sensor embedded in the distribution line in advance. In an optional embodiment, the calculation model is sent by the upper computer or the server, or the calculation model is set for the control module.
That is, when the calculation model is sent by the upper computer or the server, the calculation model can be set in advance according to the power utilization and transmission condition of the current factory, and the electric power is obtained to belong to the normal threshold relation range.
When the calculation model is set for the control module, the calculation model can be set through the application parameters input by the input module and the threshold relation range generated by the calculation of the control module.
The input module is further used for inputting one or more application parameters of the current time, the current season, the current geographic position information and the current application type.
In an optional embodiment, the control module is further configured to generate different threshold relationship ranges according to the application parameter.
