Detailed Description
In order to make the technical solutions and advantages of the present invention clearer, the following describes the technical solutions in the embodiments of the present invention clearly and completely with reference to the drawings in the embodiments of the present invention:
the centralized monitoring system for the flow battery shown in fig. 1 specifically includes a server terminal, an information acquisition unit, a management unit, and a monitoring unit.
The server terminal comprises at least two servers, and the two servers are designed in a redundant mode. When one server fails in a working state, the other server continues working, the server taking over the failed server to manage the data and update the data in real time, the server working after the failed server is recovered transmits the backup data information to the recovered server, and the data information in the two servers is synchronized in real time. The server terminal comprises the server 1 and the server 2, when the server 1 fails, the server is automatically switched to the other server 2, and when the server 1 recovers due to failure, data are automatically synchronized, so that the data reliability is improved.
The data acquisition unit transmits acquired data information to the server terminal through the first transmission path, and the server terminal transmits control instruction information to the data acquisition units through the second transmission path. Namely, the BMS system of the network communication part adopts a double-network-port design, the network transmission adopts a VLAN technology to isolate a control network and a collection network, the network transmission is divided into different network segments, important information such as voltage, current, active power, reactive power, start and stop, parameter issuing and the like is transmitted through a VLAN1, and parameters with lower real-time requirements such as temperature, pressure, flow and the like and larger data volume are transmitted through a VLAN2, so that the possibility of data storm is reduced, and the speed and the stability of the control network are increased.
The management unit carries out frame type management on the data: the flow battery under the monitoring of the system is provided with a plurality of regions or structural units, the regions or structural units are named as a plurality of sub-units according to sequence, all parameters of the flow battery are stored in one main unit, and any one sub-unit is combined with the parameters in the main unit to form variable data in a data use process.
As shown in fig. 2, in the centralized monitoring system for a flow battery, when a management unit performs frame-type management on data: taking 100 energy storage monitoring systems as an example, that is, N is 100, the traditional system parameter design needs to design 100 sets of parameters of the energy storage monitoring systems, and by adopting the frame-type management method of the design, 1 parameter is established for each type, by establishing the energy storage system subunits, the total unit and the subunits are combined to represent the difference of 100 sets of parameters, by taking voltage as an example, the traditional method needs to establish voltage of "1 unit voltage" and "2 unit voltage" … … "100 unit voltage", by adopting the design of the scheme, only the parameter needs to be established as "voltage", and by adding a character string of "1 unit to 100 units" in front of the "voltage" parameter through the operation of high-level language, the voltage parameter of "1 to 100 units" is represented. The same is true for the method of establishing "current" or other parameters, and the more variables, the more software controls are saved, and the more development time is saved.
As shown in fig. 3, in the centralized monitoring system for a flow battery, the software architecture design — screen design also takes 100 energy storage monitoring systems as an example, that is, N is 100, the traditional software screen design needs to design 100 sets of screens of the energy storage monitoring systems, and displays different screens of the energy storage systems by switching different screen modes, and the traditional design method needs to design 100 sub-screens as a system parameter display screen, so that the software pressure is very high; by adopting a frame type management mode, pictures of the same type only need to finish 1 picture, as shown in figure three, the first row is a universal template picture, the same type only needs to be established once, the picture is not connected with an actual variable and only connected with a universal part of the variable, if the variable of 1 unit pressure needs to be connected, only the type of the pressure character needs to be connected, and a unit is added before the pressure character in a high-level language mode to combine a new unit pressure; when the two units of the energy storage system need to be represented, only the one unit needs to be replaced by the two units through the high-level language, the pictures do not need to be switched, and similarly, other variable change modes are the same, so that each type of picture only needs to be established by 1 pair, and each energy storage unit does not need to be established independently; the method can be adopted for designing pictures such as control, curves, reports and the like, so that the design work of the pictures and the connection work of parameters are greatly reduced for the establishment of large-scale centralized monitoring, the pressure of a software system is reduced, and the development time is also saved.
The monitoring unit receives the data information after the arrangement transmitted by the management unit, and performs picture type display and real-time monitoring on the data. The monitoring unit carries out modular management on the acquisition, display and control pictures; namely, a template is established on the same picture, and different battery parameters are transmitted and output by calling the template picture for multiple times through changing the name of the subunit in the frame type parameter design. Therefore, the management unit is simple in design and the number of pictures is reduced.
A monitoring method of a centralized monitoring system of a flow battery comprises the following steps:
s1: collecting working condition information of a plurality of areas or structural units of the flow battery under the monitoring system, and transmitting the collected data information to a server terminal through a first transmission path;
s2: the server terminal transmits control instruction information of a plurality of areas or structural units to the management unit through a second transmission path;
