Abstract
The utility model relates to a heliostat group control device with a bottom-layer control function of a heliostat. The heliostat group control device at least comprises two controllers with a heliostat bottom sub-group control function and an automatic sun move tracking function. When one controller fails to work, automatically switching into the other controller can be realized. The heliostat group control device can reduce production cost, prevents the communication from traffic congestion in the communication process, achieves high-precision and automatic tracking of the sun move trajectory, and improves the work efficiency of a heliostat field.
Description
Technical field
The utility model belongs to the fields such as tower type solar collecting system, industrial automation, is 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 exploitation.
In the tower type solar collecting system pilot scale stage, the controller of being responsible for heliostat subgroup scheduling and control task usually expensive and relatively poor with heliostat group's communication quality, communications cost is expensive.under prior art, heliostat subgroup controller is typically used as analog signal storage and the application that heliostat is followed the tracks of the projection solar facula, can't have simultaneously scheduling and control function to heliostat concurrently, can not give full play to heliostat subgroup controller function, caused 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 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, therefore, heliostat subgroup control system needs rationally to improve system redundancy, increase system reliability.
The utility model content
For the problems referred to above, the utility model provides a kind of heliostat control device that has heliostat group control function concurrently in order to overcome a prior art difficult problem.
The technical solution of the utility model 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, open subgroup control function, be responsible for simultaneously the control task of separate unit heliostat for other one.
Device described in the utility model can be therein one when out of service in the situations such as outage, communication obstruction, natural cause impact, overhaul of the equipments, in time enable the subgroup of another spare group control device and control function, guarantee that the heliostat subgroup can work, improve mirror field operating efficiency.
The utility model can reduce production costs, and prevents the communication obstructing problem in 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; In figure: 1. list and control instruction; 2. have heliostat concurrently and control the subgroup control device of function; 3. incident sunshine; 4. standby have the subgroup control device that heliostat is controlled function concurrently; 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 concurrently and control function subgroup control device (2).
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), according to the running status of each heliostat in feedback signal judgement heliostat subgroup (5).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 heliostat subgroup (5), the heliostat in this subgroup can reflected sunlight (7) to heat collector (6), complete the reception of solar energy.Device described in the utility model 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 completing above-mentioned work.
Control the subgroup control device (2) of function when breaking down when having heliostat concurrently, system can in time detect fault-signal, and enable a standby heliostat that has concurrently and control function subgroup control device (4), continue to realize heliostat subgroup (5) is 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, open subgroup control function, be responsible for simultaneously the control task of separate unit heliostat for other one.
