Embodiment
Below in conjunction with accompanying drawing, illustrate the present invention.
As shown in Figure 1, heliostat controller address configuration mode process flow diagram of the present invention, its embodiment is: heliostat controller and address arrange on instrument has a slice for the chip of short-distance wireless communication, can adopt non-contacting mode at the scene, and heliostat is carried out to address setting.According to the spacing of heliostat, the transmission range of General Requirements wireless telecommunications is less than 0.5m, and to prevent certain heliostat being carried out to address while arranging, around other heliostats receive address date and maloperation.By address, arrange, can make each heliostat controller have a fixing address, be convenient to heliostat to manage and control, and grouping is arranged according to certain rules.
After address configuration completes, heliostat controller receives the solar tracking data that host computer timesharing issues successively, makes corresponding heliostat carry out solar tracking action; Complete the heliostat of solar tracking action, the mode by self-locking realizes heliostat locking position
Wireless communication mode in the present invention includes but not limited to following content: the mode communication of infrared communication, WIFI, bluetooth, ZIGBEE and other 2.4G and 433MHz frequency.
By such address set-up mode, can simplify the requirement to erection sequence and installation site in on-the-spot heliostat installation process, also simplified the work that arranges of on-the-spot heliostat address, do not need the electric box of opening heliostat controller to carry out hardware dial-up or carry out address setting by modes such as hardwire communications simultaneously.
During concrete enforcement, require first heliostat controller to be powered on, to guarantee the externally communication of heliostat controller.Artificial hand-held heliostat address arranges instrument near the heliostat that address need be set, and the distance between heliostat need meet following requirement:
1) address arranges controller and the heliostat normal communication that address need to be set;
2) heliostat that does not need address is set can not received communication information.
Address arranges the heliostat that instrument need carry out address setting prior to need and sets up communication, address arranges instrument address information is sent to heliostat controller afterwards, the information that after the setting of heliostat controller completes, reply has arranged, arranges in address and on instrument, shows address configuring condition.
As shown in Figure 2 and Figure 3, the embodiment that realizes heliostat locking position by electronics mode in the present invention is: when heliostat 1 rotates, the needed rated current of electric machine controller 4 output is carried out drive motor 2; When heliostat 1 stops locking, by controlling motor internal coil 3 by electronic switch short circuit (Q1 and Q3 are open-minded, Q2 and Q4 by), utilize motor self-characteristic to pin whole gearing.Heliostat controller by the power supply 5 of single tower type solar generating set successively timesharing provide electric energy or other power supplys successively timesharing electric energy is provided, the present invention does not limit.
As shown in Figure 4, in the present invention, the embodiment of multiple heliostats single supply time sharing power supply describes with instantiation.For example, the Switching Power Supply of 1 200W capacity powers to eight groups of heliostat controllers, setting synchronization only has one group of heliostat controller controlling corresponding heliostat execution solar tracking action, solar tracking motor rotates, the solar tracking motor of other seven groups of heliostat controllers does not rotate, but can wait for solar tracking order, and upper one group of heliostat controller is finished by the time, next group starts to carry out again, and the order of concrete execution solar tracking is dispatched by host computer.
Concrete execution step is as follows:
Host computer is according to current time, will solar tracking data (such as: the angle that heliostat rotates) issue first group of heliostat controller;
First group of heliostat controller received solar tracking data, and K1 opens, and solar tracking motor rotates, and first group of heliostat carried out solar tracking action;
After upper one group of heliostat command execution completes, K1 closes, and host computer issues solar tracking data to second group of heliostat, and K2 opens second group of heliostat and carries out solar tracking action,
The like, realize many group heliostats and moved by the execution solar tracking of same Power supply.
By above step, whole heliostat controller system just can be used separate unit Switching Power Supply to power, thereby reduces the reliability of Switching Power Supply cost and raising system.
The preferred embodiment of the present invention is just for helping to set forth the present invention.Preferred embodiment does not have all details of detailed descriptionthe, and also not limiting this invention is only described embodiment.Obviously, according to the content of this instructions, can make many modifications and variations.These embodiment are chosen and specifically described to this instructions, is in order to explain better principle of the present invention and practical application, thereby under making, technical field technician can utilize the present invention well.
