Abstract
The invention relates to a heliostat group control device with a heliostat bottom layer control function. The heliostat group control device comprises at least two controllers with a heliostat fundamental subgroup control function and an automatic sun movement tracking function, wherein one controller is automatically switched to another when failure occurs. The heliostat group control device has the advantages that the production cost can be reduced, the communication blockage problem in the communication process can be prevented, the high-precision automatic sun movement track tracking is realized, and the work efficiency of a heliostat field is improved.
Description
Technical field
The invention belongs to the fields such as tower type solar collecting system, industrial automation, be specifically related to control device and the system of tower type solar collecting system heliostat subgroup.
Background technology
World's environmental protection and energy problem highlights day by day at present, and society increases the demand of clean energy resource, and solar energy high temperature high-power applications technology is rapidly developed as emerging regenerative resource industry.In tower type solar thermal-arrest system mirror station control system, the specification requirement of heliostat group control device high performance/low cost and high reliability is the target of pursuing in present system research and the exploitation.
In the tower type solar collecting system pilot scale stage, the controller of being responsible for the scheduling of heliostat subgroup and control task usually expensive and relatively poor with heliostat group's communication quality, communications cost is expensive.Heliostat subgroup controller is typically used as analog signal storage and the application that heliostat is followed the tracks of the projection solar facula under the prior art, can't have simultaneously scheduling and control function to heliostat concurrently, can not give full play to heliostat subgroup controller function, cause the waste of resource
In addition, in tower type solar thermal-arrest system mirror station control system, separate unit heliostat subgroup controller is breaking down, can't the assurance system continue normal operation, if when existing two or many s' heliostat subgroup controller just can avoid a controller failure or maintenance, system is still stable, and therefore, heliostat subgroup control system needs rationally to improve system redundancy, increase system reliability.
Summary of the invention
For the problems referred to above, the present invention provides a kind of heliostat control device that has heliostat group control function concurrently in order to overcome a prior art difficult problem.
Technical scheme of the present invention is as follows:
A kind of heliostat group control device that has heliostat bottom control function concurrently, it comprises that at least two have heliostat bottom group control function concurrently and from the controller of motion tracking sun operation function, one when breaking down, automatically switches to another controller;
Under normal circumstances, wherein an estrade group control device closes closed subgroup control function, and only the control task of responsible separate unit heliostat is then opened subgroup control function for other one, is responsible for simultaneously the control task of separate unit heliostat.
Device of the present invention can be therein one because when out of service in the situations such as outage, communication obstruction, natural cause impact, overhaul of the equipments, in time enable the subgroup control function of another spare group control device, guarantee that the heliostat subgroup can work, improve mirror field operating efficiency.
The present invention can reduce production costs, and prevents the communication obstructing problem in the communication process, realizes High Precision Automatic tracking running track from sun, improves mirror field operating efficiency.
Description of drawings
Fig. 1 is mirror field neutron group control device connection layout; Among the figure: 1. list and control instruction; 2. have the subgroup control device of heliostat control function concurrently; 3. incident sunshine; 4. the subgroup control device that has heliostat control function concurrently for subsequent use; 5. heliostat subgroup; 6. heat collector; 7. reflected sunlight.
The specific embodiment
As shown in Figure 1, under the condition of abundance at sunshine, comprise the list of position of sun data, meteorological data, heat collector temperature data and instruction (1) and come downwards to and have heliostat control function subgroup control device (2) concurrently.
At first, a subgroup control device (2) that has heliostat control function concurrently carries out polling communication to all heliostat devices in the scope of heliostat subgroup (5), judges the running status of each heliostat in the heliostat subgroup (5) according to feedback signal.Secondly, the list after described subgroup control device will be resolved comes downwards to every heliostat controller of heliostat subgroup (5).When incident sunshine (3) is radiated in the heliostat subgroup (5), the heliostat in this subgroup can reflected sunlight (7) to heat collector (6), finish the reception of solar energy.Device of the present invention can also be controlled the separate unit heliostat and follow the tracks of the sun and flare is projected to the heat collector surface when finishing above-mentioned work.
When the subgroup control device (2) that has heliostat control function concurrently when breaking down, system can in time detect fault-signal, and enable a heliostat control function subgroup control device (4) that has concurrently for subsequent use, continue to realize heliostat subgroup (5) are controlled.
Claims (2)
1. heliostat group control device that has heliostat bottom control function concurrently, it is characterized in that it comprises that at least two have heliostat bottom group control function concurrently and from the controller of motion tracking sun operation function, one when breaking down, automatically switch to another controller.
2. control device as claimed in claim 1, it is characterized in that: under normal circumstances, wherein an estrade group control device closes closed subgroup control function, the only control task of responsible separate unit heliostat, then open subgroup control function for other one, be responsible for simultaneously the control task of separate unit heliostat.
