In addition, the core processor prestores basic information of each heliostat 2, and the basic information at least includes the number or the coordinates of each heliostat 2. Because the address setting information fed back by the heliostat 2 also comprises heliostat numbers or coordinates, the core processor can screen out the address setting information of the non-target heliostat groups according to the address setting information fed back by the heliostat, and issue a factory-reset instruction to the heliostat 2 corresponding to the address setting information, so as to ensure that only the address of one group of target heliostat groups is set at a time.
Specifically, as shown in fig. 2 and 3. The heliostat address setting device 1 includes: a housing 101, a display screen 102 (display module), a key module (on/off button 103, address setting button 104, address resetting button 105), and an antenna 106 are arranged on the surface of the housing 101; a core processor, a wireless communication transmitting module (transmitting module), a wireless communication receiving module (receiving module), and the like are disposed inside the housing 101. The display module, the key module, the wireless communication transmitting module and the wireless communication receiving module are all electrically connected with the core processor and are controlled by the core processor.
The display module is used for displaying the address setting instruction sent by the key module and the address information fed back by the heliostat 2. The display module may be a non-touch display 102 or a touch display 102.
The key module is a specific implementation of an address setting module, and includes an on/off button 103, an address setting button 104, and an address resetting button 105. As the name implies, the key module can implement the functions of the heliostat address setting device 1, such as power-on, power-off, address setting, address resetting, and the like. Further, the housing 101 may be provided with a touch-sensitive display screen 102 formed by integrating a display module with the key module without keys.
And the core processor converts the address setting instruction sent by the key module into a radio signal and transmits the radio signal to the wireless communication transmitting module.
And the wireless communication transmitting module is electrically connected with the core processor, converts the radio signal sent by the core processor into a high-frequency oscillation electric signal and transmits the high-frequency oscillation electric signal to the heliostat 2 through a transmission medium.

It is known that the signal strength is attenuated as the distance increases, and therefore, the signal strength received by the heliostat 2 is different depending on the distance between the heliostat address setting device 1 and the heliostat 2, and generally, the larger the distance is, the weaker the signal is. The radiation range of the high-frequency oscillation electric signal sent by the wireless communication transmitting module of the heliostat address setting device 1 is (0, 50m), and in order to ensure that each heliostat can receive the signal, a signal intensity adjusting module is arranged in the core processor and used for automatically adjusting the intensity of the radio signal according to the position of the heliostat 2.

EXAMPLE III
As shown in fig. 4, the present invention further provides a heliostat address setting system, which includes the heliostat address setting apparatus 1 in the second embodiment, a heliostat 2; the heliostat 2 receives the high-frequency oscillation electric signal sent by the heliostat address setting device 1, detects the intensity value of the high-frequency oscillation electric signal, automatically generates the address of the heliostat 2 according to the intensity value and the built-in heliostat address setting standard, and feeds back the address setting information of the heliostat 2 to the heliostat address setting device 1.
The heliostats 2 are arranged in a group unit in order from the near side to the far side. The heliostat address setting standard is a standard that satisfies the conditions of the data table in which the signal intensity corresponding to the heliostat address value is made according to the difference in the signal intensity of the address setting instruction received by each heliostat 2.
Specifically, the method for making the data table with the signal intensity corresponding to the address value of the heliostat is as follows:
the closer to the heliostat address setting device 1, the greater the signal intensity value; and the further away from the heliostat address setting device 1, the smaller the signal intensity value. Therefore, after each heliostat 2 in the heliostat field is installed, the wireless signal sending device is adopted to send wireless signals at the accessory of the heliostat 2 at the forefront, and then the practical signal strength detection device detects the wireless signal strength values received by the heliostats 2 one by one and records the wireless signal strength values. If the intensity of the wireless signal received by the first-surface heliostat 2 is 10dBm, the intensity of the wireless signal received by the second-surface heliostat 2 is 8dBm, and the intensity of the wireless signal received by the third-surface heliostat 2 is 6dBm, the heliostat address value is configured according to the measured intensity of the wireless signal. If the wireless signal intensity is in the range of [10.5,9.5], the corresponding address value is 1; the wireless signal strength is in the range of [8.5,7.5], and the corresponding address value is 2.
In addition to the method for configuring heliostat addresses according to the wireless signal strength received by the heliostats 2, a standard value may be set, the strength value obtained by detecting the wireless signal received by each heliostat may be compared with the standard value, and the heliostat addresses may be configured according to the difference value generated by the comparison. The standard value may be a strength value at the time of transmitting the wireless signal, or may be a strength value of the wireless signal received by the heliostat 2 closest to the wireless signal transmitting device. Next, the strength value with the strongest received signal (i.e., the first-side target heliostat) is used as a signal strength standard value, the standard value is written into the control module of the heliostat 2, and each heliostat 2 calculates the address setting signal strength received by itself and then compares the calculated signal strength with the written standard value to calculate a difference value. For example, the difference in signal strength between the second-surface heliostat address receiving terminal and the first-surface heliostat address receiving terminal is 3dBm, the difference in signal strength between the third-surface heliostat address receiving terminal and the second-surface heliostat address receiving terminal is 6dBm, and so on. Then, the heliostat 2 performs address setting according to an internal program based on the difference between the signal intensity and the standard signal intensity. For example, the address is set to 1 when the signal strength comparison difference is 0-3dB, and the address is set to 2 when the signal strength comparison difference is 4-6 dB.
As shown in fig. 5, the heliostat 2 includes a column 201, a base 202, an electric box 203, and a flat mirror 204. One end of the upright 201 is arranged on the base 202, the other end of the upright 201 is mechanically connected with the plane mirror surface 204 through a connecting device, and the electric box 203 is arranged on the connecting device. The electric box 203 is at least provided with a control module and a wireless communication module, the wireless communication module receives an address setting instruction sent by the heliostat address setting device 1, the control module processes the address setting instruction, calculates the signal intensity of the address setting instruction, sets an address according to the signal intensity, and feeds back the address setting information to the heliostat address setting device 1 through the wireless communication module. In addition, the control module has the function of driving the heliostat to rotate at the same time. The address setting signal at least comprises a received signal strength value, a signal strength difference value, a heliostat number, a heliostat coordinate and a heliostat address value. In addition, a GPS positioning module may be provided in each heliostat 2 to measure the coordinates of each heliostat 2. Before address setting, coordinates of each heliostat 2 are made into a data table and stored in the heliostat address setting device 1 in preparation for subsequent address setting.
Data interaction is carried out between this heliostat address setting device 1 and the heliostat 2 through wireless communication's mode, and its wireless communication module who adopts can be any one in bluetooth, wiFi, NFC, zigBee. The heliostat address setting device 1 sends an address setting instruction to the heliostat 2, the heliostat 2 receives an electric signal representing the address setting instruction, the address setting is automatically completed through the processing of each module in the internal electric box 203 of the heliostat 2, the address setting information is fed back to the heliostat address setting device 1, the heliostat address setting device 1 can store or export the received address setting information, the searching is convenient, and the smooth proceeding of the subsequent work is facilitated.
The following briefly introduces the operation process of the heliostat address automatic setting system of the invention, the address setting process is shown in fig. 6, and the specific operation steps are as follows:
the method comprises the following steps: the heliostat address setting device 1 is manually held, stands at the position of each heliostat group box, and issues an address setting instruction.
Step two: the heliostat 2 automatically performs address setting according to the received wireless signal strength.
In the second step, since the received wireless signal strength is different depending on the distance between the heliostat 2 and the heliostat address setting device 1, the heliostat 2 is internally provided with a code, and the wireless signal strength is compared with the address setting data table to obtain the address of the heliostat 2 and internally set the address.
Step three: the heliostat 2 feeds back address setting information to the heliostat address setting device 1, and if the setting fails, the heliostat address setting device 1 issues an address resetting instruction to reset; if the setting is successful, the user goes to the next lens group position and repeats the address setting steps.
In step three, if the heliostat address setting device 1 receives heliostat feedback information with failed setting, the address of the group of heliostats needs to be reset, an instruction is issued through the address reset button 205 to enable the heliostat with the currently set address to be in a factory setting state, then the address setting button 204 is pressed again, the wireless signal intensity is automatically adjusted inside the core processor, and the heliostat address is reset.
Step four: the heliostat address setting device 1 compares the address setting information fed back by each heliostat 2 with the prestored basic heliostat information, screens out the address setting information of the non-target heliostat group, and issues a factory resetting instruction to the heliostat 2 corresponding to the address setting information.
