S2, according to the rainwater information and the comparison result of the first brine concentration value and a preset value, executing a rainproof command opening or a rainproof command closing so as to control the rainproof plastic mat 3 to shade or open the salt pan; the preset value is a standard brine concentration value set for ensuring the yield of the salt pan.
The brine concentration is the salt content of brine in unit volume, the salt yield of the salt field can be directly influenced by the concentration of the brine, and the brine concentration value of the salt solution in the salt field can be used as an index of the salt yield of the salt field. In step S2, the rainwater information of the area where the salt pan is located and the comparison result of the first brine concentration value and the preset value of the salt pan are used as conditions for judging whether the rainproof plastic cover needs to be unfolded to cover the salt pan or needs to be folded to open the salt pan, in other words, comprehensive analysis and calculation are performed on the rainwater information and the comparison result of the first brine concentration value and the preset value, so that the rainproof plastic cover is unfolded at a more proper time to cover the salt pan, the rainwater is shielded, so that the rainproof plastic cover is prevented from being unfolded too late, the rainwater enters the salt pan, the brine concentration of the salt pan is reduced, the salt yield of the salt pan is influenced, or the rainproof plastic cover is folded at a more proper time to open the salt pan, so that the evaporation of the brine is prevented from being folded too late, and the salt crystallization speed is influenced. The preset value is a standard brine concentration value set for ensuring the yield of the salt field, for example, as the brine concentration of the salt pond of the salt field is mainly increased by evaporating water, and then salt is produced by crystallization, in other words, if the brine concentration of the salt field is too low, the salt production speed, namely the salt production amount, is influenced, if the brine concentration of the salt field is too high, the crystallization phenomenon occurs, and the salt production amount of the salt field is influenced, so that the brine of the salt field needs to be continuously kept at a standard concentration value, and therefore, the normal salt production speed can be ensured, and the salt production amount of the salt field can be ensured.

In addition, when the first brine concentration value is greater than the preset value, the brine concentration of the salt pan can be considered to be too high at this time, the salt yield of the salt pan is further influenced, the area where the salt pan is located is detected to not rain through the raindrop sensor, if the rainproof plastic film is not unfolded to shield the salt pan, the water evaporation capacity of the salt pan is reduced, the salt yield of the salt pan is further influenced, and therefore, a rainproof command is sent to the opening and closing device through the control device, the opening and closing device is utilized to shield the salt pan, so that the water evaporation capacity of the salt pan is effectively reduced, the crystallization phenomenon which is unfavorable for the salt yield is avoided due to the fact that the brine concentration of the salt pan is further increased, and stable salt production is realized.
When the first brine concentration value is larger than the preset value, the brine concentration of the salt field can be considered to be too high, the salt field can possibly appear a crystallization phenomenon which is unfavorable for salt yield, the salt yield of the salt field is further influenced, the rain information of the area where the salt field is detected to be rain information through the rain sensor, at the moment, a rain-proof closing command is sent to the opening and closing device through the control device, the opening and closing device is used for opening the salt field, so that the salt solution of the salt field can be diluted by rain water, the first brine concentration value is reduced to the preset value, and crystallization salt production is carried out, so that the salt yield of the salt field is ensured.

After raining, obtaining a second brine concentration value of the salt pan again;
and when the second brine concentration value is smaller than the preset value, executing the rainproof opening command to control the rainproof plastic cover to shield the salt pan.
It should be noted that after the salt solution of the salt pan is diluted by rainwater so as to reduce the brine concentration, if the salt solution of the salt pan is diluted by rainwater all the time, the brine concentration value of the salt pan is too low, so that the salt yield of the salt pan is affected, so that the second brine concentration value of the salt pan is obtained again, the second brine concentration value is compared with the preset value, when the second brine concentration value is smaller than the preset value, a rainproof opening command is sent to the opening and closing device through the control device, the rainproof opening command is executed by the opening and closing device so as to control the rainproof plastic film to be unfolded to shield the salt pan, the rainwater is prevented from being blocked, the salt solution of the salt pan is prevented from being diluted continuously by the rainwater, the brine concentration of the salt pan is effectively avoided to be too low, and the salt yield of the salt pan is further ensured.

And when the rainwater information is not raining information and the first brine concentration value is smaller than the preset value, executing the rainproof command to control the rainproof plastic cover to open the salt pan.
It should be noted that, when the first brine concentration value is smaller than the preset value, the brine concentration of the salt pan can be considered to be too low at this time, and the salt can be produced by crystallization only by evaporating water, so that the salt yield of the salt pan can be directly affected by the too low brine concentration of the salt pan, the rain information of the area where the salt pan is detected by the raindrop sensor is not rainy information, at this time, a rain-proof command is sent to the opening and closing device by the control device, and the rain-proof plastic mat is closed by the opening and closing device to open the salt pan, so that the brine concentration of the salt pan can be gradually increased by naturally evaporating the water of the salt pan, and the salt yield of the salt pan is gradually increased.
In one embodiment of the invention, as shown in fig. 2, the rain-proof control method for salt pan photovoltaic further includes:
Obtaining a second brine concentration value of the salt pan again;
And when the concentration value of the second brine is larger than the preset value, executing the command for opening the rain-proof, and controlling the rain-proof plastic cover to cover the salt pan.
