Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings by way of specific examples, which are illustrative of the present invention and are not limited to the following embodiments.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.
Fig. 1 is a schematic block diagram of a structure of a local monitoring system for a storage battery of a substation according to an embodiment of the present invention, and as shown in fig. 1, the system includes: the device comprises a storage battery state detector, a controller, a memory and a display screen.
The storage battery state detector, the memory and the display screen are respectively and electrically connected with the controller. The battery condition detector is used to detect battery condition data including internal resistance, current, voltage and temperature of the battery, although it will be appreciated that other battery condition data may be detected by a user as desired. The storage battery state detector transmits the detected data to the controller, the controller analyzes the received data and displays the data on the display screen, the data are stored in the memory, and the data in the memory provide data support for local display.
It should be noted that the display screen displays the battery state data, and may display the current detection data or the historical detection data. Specifically, a real data display unit and a historical data display unit are arranged on a display screen; the real-time data display unit is used for displaying real-time detection data, the historical data display unit is used for displaying historical detection data, and fault data are displayed in a highlighted mode in the historical display unit. The maintainer is in the maintenance in-process, can learn current data and historical data directly perceived, and trouble data show with high bright form, conveniently look over.
The display screen adopts touch display screen, and more historical data etc. can be looked over to maintainer accessible page turning mode etc..
For making things convenient for the maintainer to carry out the battery overhaul, provide more effective data for the maintainer, in this embodiment, the controller adjusts storage data quantity according to the battery state.
Specifically, the controller sets the storage threshold of the memory to a first threshold and a second threshold, the first threshold being smaller than the second threshold. When the state of the storage battery is normal, the controller sets the storage threshold value of the storage at a first threshold value; when the state of the battery is abnormal, the controller sets the storage threshold value of the memory at a second threshold value. When the storage capacity of the memory reaches the threshold, the controller deletes the part of the data stored in the memory for the longest time, for example, when the state of the storage battery is normal, the stored data in the memory reaches the first threshold, at this time, the part of the data stored for the longest time is deleted to make free space for storing the latest data, the stored data can be sorted from far to near according to the storage time, the part of the data at the upper side in the sorted list is deleted, and of course, how many pieces of data or how much capacity of data are deleted can be set by the user.
When the storage battery is normal, less data are stored, and the system operation efficiency is guaranteed; when the storage battery breaks down, the storage threshold value is increased, storage of more data is achieved, so that maintenance personnel can obtain more data references conveniently, and the data states before and after the storage battery breaks down can be mastered.
However, in practical application, there is a possibility that the maintenance personnel may not perform maintenance in time, and at this time, in order to prevent the data with the largest maintenance reference value from being deleted, the embodiment is further provided with a spare memory, and the spare memory is electrically connected with the controller. The controller monitors whether the state of the storage battery is recovered to be normal or not in real time, and if the state of the storage battery is not recovered to be normal after a certain time from the fault, partial fault data before and after the initial fault is stored into the standby memory. It should be noted that after the storage battery fails, detection data are continuously stored in the memory, although the threshold of the memory is increased by the second threshold, if the maintainer does not overhaul in time, the risk of deleting the failure data still exists, and therefore, if the maintainer does not overhaul normally within a certain time after the failure, the embodiment transfers part of data before and after the failure to the standby memory so as to store state information before and after the failure, provide data with a high reference value for subsequent overhauls, and improve overhauling efficiency.
In addition, the embodiment is also provided with a first local alarm and a second local alarm; the first local alarm and the second local alarm are respectively electrically connected with the controller; when the controller detects the storage battery fault according to the storage battery state data, triggering a first local alarm to give an alarm; when the controller transfers part of fault data in the initial fault to the spare memory, the local alarm is triggered to alarm. When a fault occurs, the first local alarm is triggered to alarm, and the second local alarm is triggered to alarm when the fault does not exist for a long time.
Meanwhile, the wireless communication module is further arranged in the embodiment and electrically connected with the controller, and the controller sends the detection data and the alarm information to the rear end through the wireless communication module. The method is characterized in that a warning is given to a maintainer when a fault occurs, and the maintainer is informed of the need of maintenance; if the maintenance is not carried out for a long time, the reminding is sent to the maintenance personnel again, and the maintenance personnel are informed to need to carry out maintenance as soon as possible.
According to the local monitoring system for the storage battery of the transformer substation, provided by the embodiment of the invention, the storage device is arranged for storing detection data, the quantity of the stored data can be adjusted according to the state of the storage battery, when the storage battery has a fault, the stored data is increased, data support is provided for maintenance, and when the storage battery is normal, the quantity of the stored data is reduced, so that the operation efficiency of the system is prevented from being influenced; set up the display screen simultaneously and show battery state data in local real time, make maintainer can observe data, the easy access. The invention provides data support by the data stored in the memory, and displays the state data and the historical data locally in real time by the display screen, so that the maintainers can conveniently know the state of the storage battery, and the overhauling efficiency is improved.
The above embodiment of the local monitoring system for the storage battery of the substation is described in detail, and based on the local monitoring system for the storage battery of the substation described in the above embodiment, the embodiment of the invention also provides a local monitoring method for the storage battery of the substation corresponding to the local monitoring system for the storage battery of the substation.
