[0038] Figure 2 It is a schematic diagram of the chicken house partitions of the present invention;

[0039] Figure 3 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0040] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] Example 1

[0042] like Figure 1 , 3 As shown, a lighting control system and method for laying hen farming, first of all, due to the development of modern large-scale farming, chicken houses are usually built longer to meet large-scale farming. Due to the large span of the chicken house and the influence of the terrain environment, each area in the chicken house is affected differently by the external light. Therefore, in order to ensure that the lighting conditions in each area of ​​the chicken house can meet the farming needs, the chicken house is divided into several areas according to the influence range of each lamp arranged in the chicken house, and each area is marked, and the light transmission point of each area is determined, such as Figure 2 Then, a real-time monitoring device is installed in each area. The information monitoring module in the real-time monitoring device includes an incident light intensity monitoring module installed outside each light transmission point in each area, a penetrating light intensity monitoring module installed inside each light transmission point in each area, and a chicken activity monitoring module installed in each area. At the same time, an execution controller is installed on the lamp responsible for each area.

[0043] Before actually controlling the lamps, turn off all the lamps in the chicken house. At this time, the incident light intensity monitoring module monitors the incident light intensity from the outside to each area of ​​the chicken house, and the penetration light intensity monitoring module monitors the light intensity penetrating through each light transmission point into each area of ​​the chicken house. The data is then sent to the data preprocessing module for processing, so that the light transmittance α of each area of ​​the chicken house can be determined as:

[0044]

[0045] Where E(a) is the incident light intensity in each area of ​​the chicken house, E in,i (a) is the light intensity transmitted through each light-transmitting point in each area of ​​the chicken house, and Z is the total number of light-transmitting points in each area. The light transmittance of each area is collected by the data acquisition module and then sent to the service device through the data transmission module using Internet technology. The penetrating light intensity monitoring module only works when determining the light transmittance of each full area, and can be disabled when the lamp is subsequently controlled.

[0046] When the actual control of the lamps is put into operation, the incident light intensity monitoring module is used to monitor the incident light intensity of each area of ​​the chicken house. Then the data acquisition module collects the incident light intensity information of each area of ​​the chicken house, and sends it to the service equipment through the data sending module using the Internet technology.

[0047] After the service device receives the information data sent by the real-time monitoring device through the data receiving module, the information data is written into the data temporary storage module of the real-time data processing module through the information data writing module for temporary storage. Then, the data analysis module retrieves the temporary stored incident light intensity information of the current external environment entering each area of ​​the chicken house from the data temporary storage module, and then combines the light transmittance of each area and the preset light intensity parameters required in the laying hen breeding process to determine the light intensity e that the lamps in each area of ​​the chicken house need to provide:

[0048]

[0049] Among them, E n (a) is the current incident light intensity from the outside into each area of ​​the chicken house, E o is the preset light intensity parameter required in the laying hen breeding process, α is the light transmittance of each area of ​​the chicken house, if(1,2,3) means that if condition 1 is met, result 2 is returned, otherwise result 3 is returned. Then, the instruction generation module generates the light intensity control instruction of the lamp, and the wireless transmission module uses the Internet technology to send the light intensity control instruction of the lamp to the execution controller.

[0050] After the execution controller receives the light intensity control command of the lamp through the command receiving module, it uses the command parsing module to parse the command, and then controls the power of the lamp through the execution control module to adjust the lamp to the light intensity required by the command. By accurately controlling the light intensity of each area, it can avoid the situation where manual control easily causes stress to laying hens, and at the same time avoid the situation where the light intensity in some areas of the chicken house is too high or insufficient in some areas due to unified control.

[0051] Example 2

[0052] On the basis of Example 1, when the actual control of the lamp is put into operation, the chicken activity monitoring module monitors the activities of the laying hens in each area in real time, and hands over the activity picture information to the data preprocessing module, which uses the CNN neural network algorithm to identify the behaviors of the laying hens in each area who are about to start and stop activities (the CNN neural network algorithm identifies behavioral characteristics as a common means at present, and the identification of behavioral characteristics is completed through data collection and processing, model selection and training, behavior identification and optimization steps, so the specific operation steps are not repeated here), and determines the start and stop time of the laying hens in each area of ​​the chicken house, thereby determining the activity duration of the laying hens in each area of ​​the chicken house = stop time - start time. Then, the activity duration of the laying hens in each area of ​​the chicken house within a period of time is collected by the data acquisition module, and sent to the service device by the data sending module using Internet technology.

[0053] After the service device receives the information data sent by the real-time monitoring device through the data receiving module, the information data is written into the data temporary storage module of the real-time data processing module through the information data writing module for temporary storage. Then the data analysis module retrieves the temporary activity duration of the laying hens in each area of ​​the chicken house from the temporary data storage module, and then combines the preset activity duration of the laying hens to determine the continuous illumination duration t of each area of ​​the chicken house:

[0054]

[0055] Among them, k p , k i , k d are given coefficients respectively, t(d) is the daily activity duration of laying hens in each area of ​​the chicken house within a period of time S, t o It is the preset activity time of laying hens. p When determining, let k i , k d is 0, at this time, k pStart from 0 and gradually increase until the system oscillates. Conversely, Kp at this time gradually decreases until the system oscillation disappears. Record the proportional coefficient Kp at this time. Kp is 60% to 70% of the current value. The specific selection can be determined according to the response speed required by the system. The larger the Kp, the faster the system responds. Conversely, the slower the system responds. p After confirmation, set a larger coefficient k i , and then gradually reduce k i , until the system oscillates, and then reverses, gradually increasing k i , until the system oscillation disappears. Record the k at this time i , set the coefficient k i It is 150% to 180% of the current value. The specific selection can be determined according to the response speed required by the system to avoid excessive system response. d Determination of k p The method is the same as that of , and 30% of the value when there is no oscillation can be used.

[0056] Then, the instruction generation module generates a continuous lighting control instruction for the lamp, and the continuous lighting control instruction for the lamp is sent to the execution controller through the wireless transmission module using Internet technology.

[0057] After the execution controller receives the lamp continuous illumination control instruction through the instruction receiving module, it uses the instruction parsing module to parse the instruction, and then uses the execution control module to make the lamp continue to illuminate for a corresponding period of time at the illumination intensity of Example 1. When the lamp is not needed to supplement the light intensity, the execution controller turns off the lamp through the execution control module, and the lamp still executes the continuous illumination duration instruction.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
