Description
Technical Field
The invention belongs to the field of cultivation, and particularly relates to an automatic poultry weighing method and system.
Background
Sampling and weighing the poultry during brooding and growing periods can detect the weight of the poultry and the uniformity of the weight of a group of poultry, and know the growth and development of the whole poultry group at any moment. In addition, the weight growth speed of the poultry can be effectively controlled by adjusting the feeding amount of the feed according to the weight level of the poultry, so that the poultry can keep good growth conditions in the whole brooding and growing period. The slaughter date and average weight and uniformity distribution of weight of the poultry can be estimated according to the weight growth condition of the poultry. During daily feeding or slaughter it is necessary to be able to position particularly lean poultry and to satisfy weight by weighing the poultry. Thus, poultry weighing is of great importance.
Traditional methods of weighing poultry are to select a proportion of the poultry in different areas of the farm for weighing, manually selecting a representative sample from a flock of chickens, and driving the poultry ready for weighing to a corner or a catch ring, causing the poultry to enter the catch ring to catch the sample poultry, and repeatedly capturing the sample poultry in several areas. The captured poultry was then weighed using an electronic scale. In order to obtain dynamic changes in the growth of the poultry, the poultry needs to be weighed every preset time period during the whole feeding process. For example, the method of the seven-simultaneous principle is adopted to weigh poultry, namely, the method adopts random sampling weighing of the same time, the same place, the same person, the same weighing module, the same precision and the same weighing proportion on the same day. Sampling weighing requirements the individual birds that provide the weighing must be representative of the bird population, and the weighing data can reflect the actual growth status of the entire bird population, and then record the weight using a weight analysis table. The weighing method not only disturbs the normal life of the poultry, but also is time-consuming and labor-consuming.
Currently, in one solution, the support rods and the mesh material are used to form a weighing platform, the camera is fixed above the weighing platform, and the pressure sensors for measuring the weight of the poultry are fixed at four corners of the weighing platform. When a plurality of poultry stand on the weighing platform, when the measured change of the weight of the poultry is smaller than a set threshold value, triggering the camera to obtain an image of the weighing platform area, then obtaining the number of the chickens on the weighing platform through image processing, and calculating to obtain the average weight of the poultry. The method solves the problem that human interference factors to poultry can be automatically weighed, but the number of the poultry on the weighing platform is easy to have errors by adopting image processing, and the method needs a camera, has high cost and is not suitable for free-range poultry in a large area.
In another scheme, the weighing system consists of a host machine and a plurality of slave machines, and the host machine and the slave machines are communicated. The weighing platform is designed into a telescopic cross rod, the length of the cross rod can be manually adjusted, and the number of scales is preliminarily limited. And judging the current weighing state and the number of the upper-weighing chickens by utilizing the own characteristics of the weight data. The method can replace heavy manual weighing operation to a certain extent, but has complex wiring, and when smaller poultry passes simultaneously, the error of poultry counting can be generated, so that the weighing result is error.
In summary, the poultry weighing method in the prior art is time-consuming and labor-consuming and has large error.

Detailed Description
The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.
In one embodiment of the present invention, a method for weighing poultry is provided, and fig. 1 is a schematic overall flow chart of the method for weighing poultry provided in the embodiment of the present invention, where the method includes: s1, weighing data of poultry are obtained in real time, wherein the weighing data comprise weight data and weighing time; s2, judging whether each weight data is valid or not by using a limiting filtering method, and determining a weighing serial number corresponding to the valid weight data; and S3, uploading the effective weight data, the weighing serial numbers corresponding to the effective weight data and the weighing time corresponding to the effective weight data by a server.
Specifically, in S1, weighing data of the poultry is acquired in real time using a poultry weighing apparatus, wherein the weighing data includes not only weight data and weighing time. Wherein the weight data is the weight of the poultry collected by the weighing sensor each time. The weighing time is the time of each time the weighing sensor collects the weight of the poultry. The poultry may be a chicken flock or a duck flock, etc. In S2, when no poultry passes through the weighing device, the collected weight data is 0, and when the poultry passes through the weighing device, the collected weight data is unstable due to the unstable state of the poultry on the weighing device, and the collected weight data is suddenly high or low, so that the collected weight data needs to be screened. And judging whether each weighing data is valid or not by using a limiting filtering method. The limiting filtering method is to empirically determine the maximum deviation value allowed by twice sampling, and set the maximum deviation value as A. Judging each time a new value is detected, and if the difference between the current value and the last value is < =a, the current value is valid; if the difference between the current value and the last value is greater than A, the current value is invalid and the current value is abandoned. For the effective weight data, the weighing serial number is automatically added with 1, namely the weighing serial number corresponding to the first effective weight data is 1, the weighing serial number corresponding to the second effective weight data is 2, and so on. And S3, uploading the effective weight data, the weighing serial numbers corresponding to the effective weight data and the weighing time corresponding to the effective weight data to a network service platform in real time through a convergence gateway so that the network service platform can analyze the effective weight data and display the effective weight data in real time. The real-time display comprises display of current weight data of the poultry, display of current weighing serial numbers and display of current weighing time. And filtering and cleaning the weight data through a specific filtering algorithm at the background of the network service platform, so as to ensure that the displayed data of the database are real and effective data.
According to the embodiment, the weighing data of the poultry are obtained in real time, whether the weight data are effective or not is judged by using a limiting filtering method, so that the weighing data are automatically obtained, the weight data are screened to enable weighing to be more accurate, meanwhile, the effective weight data, the weighing serial numbers corresponding to the effective weight data and the weighing time corresponding to the effective weight data are uploaded, and subsequent processing, statistical analysis and decision pre-warning are facilitated.
On the basis of the foregoing embodiment, step S2 in this embodiment specifically includes: if the last weight data is equal to 0 and the current weight data is greater than 0, recording the current weight data and a weighing serial number corresponding to the current weight data; iteratively taking the next weight data as the current weight data, and obtaining a difference value between the current weight data and the last weight data until the next weight data is 0; if the difference value is smaller than a preset threshold value, the current weight data is known to be effective, and the current weight data and the weighing serial numbers corresponding to the current weight data are recorded; or if the difference value is greater than or equal to the preset threshold value, the current weight data is invalid.
Specifically, first, theThe poultry weighing device is connected with voltage for initialization. And then the poultry weighing device searches a local wireless network and requests to join, and the data acquisition module acquires the weight of the poultry every preset time after the joining is successful. Because the weight data acquired after the poultry climbs the weighing perch is unstable and can change, the behavior of the poultry on the weighing perch once is measured for a plurality of times. As shown in FIG. 2, when the last weight is equal to 0 and the current weight is greater than 0, the poultry is just on the weighing creel, and the current weight T is recorded i . Then weight is collected at intervals of preset time length and the weight T at the moment is recorded i+1 Then judge T i+1 And T is i Whether the difference between the absolute values of (c) is smaller than a preset threshold p. When the threshold value p is smaller than the preset threshold value p, recording T i+1 The weighing serial number corresponding to the next weight data is automatically added with 1 on the basis of the last weighing serial number; when the threshold value p is greater than or equal to the preset threshold value p, then T i+1 Invalidation, giving up T i+1 By T in combination i Instead of the value of i+1 weighings. And iteratively acquiring weight data acquired next time, calculating a threshold value, and recording current weight data and a weighing serial number until the weight data acquired next time is 0. The next weight data of 0 indicates that the poultry has just left the weigh down creel. When the last time the weight data was equal to 0 and the current weight data was greater than 0, it is indicated that weighing of another poultry is started. And sending the weighing data and the weighing serial numbers to the sink node through a wireless networking module. The preset time period can be adjusted according to different time periods, such as 1s or 0.5s. The preset threshold p may be dynamically adjusted. The p-value is now smaller than the value of the incubation period because of the relatively high accuracy of the load cell used when measuring the brood birds.
In this embodiment, since the birds are moving while they are weighing on the weighing turret, the unstable weight data is required to be processed, thereby obtaining more accurate weight data.
On the basis of the foregoing embodiment, step S2 in this embodiment further includes: continuously sampling each weight data, and removing the maximum value and the minimum value in the continuously sampled weight data; an average of the weight data of successive samples after removal of the maximum and minimum values is calculated.
Specifically, each recorded weighing data is continuously sampled according to a plurality of continuous data which are not 0 in the weighing data measured by the weighing sensor. The continuously sampled data are a plurality of weighing data measured by the weighing creel when the poultry is on the weighing creel at one time. And removing one maximum value and one minimum value in the N weighing data which are sampled continuously, and then calculating the average value of N-2 weighing data which are sampled continuously after the maximum value and the minimum value are removed.
The method of combining the median average filtering method is adopted in the embodiment to overcome pulse interference caused by accidental factors, and sampling value deviation caused by pulse interference can be eliminated.
On the basis of the foregoing embodiments, the step S3 in this embodiment further includes: after the wireless local area network is established, monitoring whether a new child node requests to join; when a new child node requests to be added, judging whether the new child node accords with a local protocol; if the new child node accords with the local protocol, allowing the new child node to join and distributing a wireless local area network address for the new child node; and monitoring the new child node to upload the weighing data, and uploading the effective weight data, the weighing serial number corresponding to the effective weight data and the weighing time corresponding to the effective weight data through the wireless local area network address.
Specifically, the effective weight data, the weighing serial number corresponding to the effective weight data and the weighing time corresponding to the effective weight data are uploaded through a convergence gateway. As shown in fig. 3, the convergence gateway first turns on voltage and initializes, and then starts to register with the public network server to establish a remote transmission channel. And then establishing a wireless local area network which can be a frequency band network of 2.4G, 433M or 5G and the like through the second core processor. Monitoring is started after the wireless local area network is established to see if a new poultry weighing apparatus child node requests to join. When a new child node requests to join, judging whether the new child node accords with a local protocol, and when the new child node accords with the local protocol, allowing the new child node to join and distributing a wireless local area network address for the new child node, and entering a monitoring uploading data link. And after that, the online poultry weighing device starts to be monitored to upload weighing data, when the weighing data is uploaded, the weighing data is processed, and the weighing data is sent to a public network server address. At this time, a circulation flow is completed, then a new poultry weighing device adding link is waited, and the next circulation flow is entered.
On the basis of the above embodiments, the step S3 in this embodiment further includes: and carrying out data processing, statistical analysis and decision pre-warning according to the effective weight data.
Specifically, the network service platform receives data sent by the convergence gateway. The basic functions of the network service platform comprise weighing data processing, statistical analysis and data decision pre-warning. The network service platform also completes real-time display of weighing data transmitted by the poultry weighing devices, when the poultry weighing devices are installed and the poultry weighing devices judge that the weighing data are effective at the time, the weighing data are uploaded to the network service platform in real time, and the network service platform analyzes and displays the weighing data. The real-time display comprises display of poultry weight, display of current weighing serial number and display of current weighing time. And filtering and cleaning the weighing data are completed through a specific filtering algorithm at the background of the network service platform, so that the data displayed in the database are real and effective data.
Statistical analysis of the weighing data included completion of calculation and analysis of average daily weight of poultry. Also included is selecting an average weight for a particular period of time based on the feeding time of the birds, such as selecting weighing data from 4-6 hours after feeding the birds, and then calculating the average weight. The average daily weight is displayed in real time in the form of a graph or bar chart to more intuitively check the change of the growth weight gain curve of the poultry. In addition, statistics of the daily exit time of the poultry, statistics of the returning time, statistical analysis of the weight uniformity of the poultry with different weights according to the weight of the poultry and the like can be completed.
The decision pre-warning of weighing data refers to decision pre-warning support of the growth weight of the poultry is completed in different stages of the growth of the poultry, such as observing average weight growth change of the poultry every day, and when the weight growth is smaller than the average weight growth speed in a certain time period, timely decision pre-warning is given to a poultry manager so that the poultry manager can adjust the feed proportioning condition and the feeding condition. Or when the weight is too fast to grow, the poultry raising manager can be timely reminded to adjust the feeding proportion and the feeding amount. In the monitoring process, the measurement of the individual poultry with smaller weight can be early-warned and positioned in time, so that a poultry manager can check whether the poultry is ill or not in real time, and the like. In addition, in the slaughtering period, the average weight of the current poultry is checked in real time by the poultry manager through the network service platform, and the optimal slaughtering date can be recommended for the poultry manager. The early warning decision information is transmitted to the poultry weighing device in real time through the bidirectional data transmission of the wireless transmission module to finish local warning. The network service platform supports related manager short message alarming and handheld terminal pushing alarming through the wireless module.
And the user can view the weighing related information of the poultry on the own farm through the network service platform. Weighing information among users is relatively independent, and data sharing among users is supported. And weighing data are gathered to a gathering gateway in a wireless mode between all the poultry weighing devices and are intensively uploaded to a remote server, so that weighing of most of poultry is ensured.
In another embodiment of the present invention, an automatic poultry weighing system is provided, and fig. 4 is a schematic diagram of an overall structure of the automatic poultry weighing system provided in the embodiment of the present invention, where the system includes: the acquisition unit is used for acquiring weighing data of the poultry, wherein the weighing data comprises weight data and weighing time; the optimizing unit is used for judging whether each weight data is valid or not by using a limiting filtering method and determining a weighing serial number corresponding to the valid weight data; and the transmission unit is used for uploading the effective weight data, the weighing serial numbers corresponding to the effective weight data and the weighing time corresponding to the effective weight data.
Specifically, the acquisition unit acquires weighing data in real time, wherein the weighing data not only comprises weight data and weighing time. Wherein the weight data is the weight of the poultry collected by the weighing sensor each time. The weighing time is the time of each time the weighing sensor collects the weight of the poultry. The poultry may be a chicken flock or a duck flock, etc. When no poultry passes through the weighing device, the acquired weight data is 0, and when the poultry passes through the weighing device, the acquired weight data is unstable and can be suddenly high or low due to the unstable state of the poultry on the weighing device, so that the optimization unit is required to screen the acquired weight data. And judging whether each weighing data is valid or not by using a limiting filtering method. The limiting filtering method is to empirically determine the maximum deviation value allowed by twice sampling, and set the maximum deviation value as A. Judging each time a new value is detected, and if the difference between the current value and the last value is < =a, the current value is valid; if the difference between the current value and the last value is greater than A, the current value is invalid, the current value is discarded, and the last value is used for replacing the current value. For the effective weight data, the weighing serial number is automatically added with 1, namely the weighing serial number corresponding to the first effective weight data is 1, the weighing serial number corresponding to the second effective weight data is 2, and so on.
