Abstract

In poultry houses the body weight of sampled chickens is measured in order to monitor the cultivation state of the growing chickens on a daily basis. However, in the prior art this task has been performed directly by humans, necessitating large manpower input. In a chicken body weight calculation method characterized in that the body weight of a chicken is calculated on the basis of the pressure distribution of the foot of the chicken standing on a sheet-form pressure sensor, the body weight of chickens in a poultry house is measured and the average value thereof can be calculated; therefore, the growth of the chickens can be monitored without effort.

Description

ニワトリの体重算出方法とニワトリの成長監視システムChicken weight calculation method and chicken growth monitoring system
　本発明は食肉用として鶏舎中で飼育される食肉用ニワトリ（所謂ブロイラー）や、採卵用のニワトリ（所謂レイヤー）の発育状態を簡便に測定することのできるニワトリの成長監視システムに関する。 The present invention relates to a chicken growth monitoring system that can easily measure the growth state of meat chickens (so-called broilers) and egg-collecting chickens (so-called layers) raised in poultry houses for meat.
　現在ニワトリはほとんどが家畜用として育てられている。ニワトリは卵および食肉として、世界中で重要な蛋白源となっている。そして、卵および食用肉としての生産性を向上させるために、ニワトリ自体を採卵に適した種と食肉用に適した種として品種改良が行われてきた。採卵用のニワトリは、レイヤーと呼ばれ、食肉用のニワトリはブロイラーと呼ばれている。 Currently, most chickens are raised for livestock. Chickens are an important source of protein throughout the world as eggs and meat. And in order to improve the productivity as an egg and edible meat, breed improvement has been carried out using the chicken itself as a species suitable for egg collection and a species suitable for meat. A chicken for egg collection is called a layer, and a chicken for meat is called a broiler.
　ブロイラーは、その肉を得るために短期間で急成長するように品種が改良されている。現在では、ブロイラーは、通常のニワトリなら４～５ヶ月で成鳥となるところ、４０～５０日で成鳥となり出荷が可能となる。また、１ｋｇの肉を得るために与える餌の量としては、牛が１５ｋｇ、豚が６ｋｇに対して、ブロイラーは、わずか２．１ｋｇでよい。すなわち、食肉用の家畜として大変生産性が高い動物となっている。 Broilers have been improved in variety so that they can grow rapidly in a short period of time to obtain their meat. Currently, broilers become adults in 4 to 5 months for normal chickens, but become adults in 40 to 50 days and can be shipped. Moreover, as for the amount of feed given to obtain 1 kg of meat, the cow needs only 2.1 kg for the broiler, while the cow is 15 kg and the pig is 6 kg. In other words, it has become a highly productive animal for livestock for meat.
　これらのニワトリの成長の監視は、ニワトリの体重を測定することで行われる。しかし、１つの鶏舎には多数のニワトリが飼育されているため、全ての個体の体重を測定するのは、大変な労力と時間を必要とする。また、ブロイラーなどは、日齢毎に体重が増加するため、体重測定に時間をかけるのは意味がない。 監視 The growth of these chickens is monitored by measuring their weight. However, since a large number of chickens are bred in one poultry house, measuring the weight of all individuals requires a great deal of labor and time. In addition, broilers and the like gain weight every day, so it does not make sense to spend time on weight measurement.
　そこで、全個体の一部をサンプリングして体重測定し、成長具合を確認する。しかし、それでも多くのニワトリを人間が集めて体重測定を行う必要がある。これはやはり大変な労力を必要とする。 Therefore, a part of all individuals are sampled and weighed to confirm the growth. However, it is still necessary for humans to collect many chickens for weight measurement. This still requires a lot of effort.
　このような状況において、ニワトリの体重を自動的に測定する提案がされている。特許文献１には、鶏舎内の例えば、給餌器や給水器のそばに設置する柵のついた体重測定器が開示されている。この体重測定器は、餌や水を摂取しにきたニワトリがその体重測定器に乗ることで、ニワトリの体重を測定し、遠隔地に設置されたデータ処理装置で集計される。 In this situation, a proposal has been made to automatically measure the weight of a chicken. Patent Document 1 discloses a weight measuring instrument with a fence installed in a poultry house, for example, near a feeder or water feeder. This weight measuring device measures the weight of a chicken when a chicken that has ingested food and water gets on the weight measuring device, and the data is collected by a data processing device installed at a remote place.
　また、特許文献２には、同様に柵のついた体重計が開示されている。なお、特許文献２は主に牛用の体重計を開示している。 Also, Patent Document 2 discloses a weight scale with a fence in the same manner. Patent Document 2 mainly discloses a weight scale for cattle.

　ニワトリは家畜の中でも多くの羽数を飼育するため、体重測定を人の手で行うのは、時間がかかる。この点特許文献１のように遠隔地で自動的にニワトリの体重を測定できるようにできれば育成の管理にかかるコストを低くすることができる。 Since chickens raise many birds among livestock, it takes time to measure weights by hand. In this regard, if it is possible to automatically measure the weight of a chicken at a remote place as in Patent Document 1, the cost for management of the breeding can be reduced.
　また特許文献２のように、牛のように大きな動物の体重を測定するのは、柵のある体重計が必要になる。しかしながら、ニワトリのように警戒心が強い動物の場合、柵を警戒して、体重計に乗らないという課題が存在する。　 Also, as in Patent Document 2, to measure the weight of a large animal such as a cow, a weight scale with a fence is required. However, in the case of an animal with strong alertness, such as a chicken, there is a problem of being on the fence and not riding on the scale. *
　本発明は上記の課題に鑑みて想到されたものであり、警戒心を抱かせることなく、個体の体重をリアルタイムで測定する方法とシステムを提供するものである。 The present invention has been conceived in view of the above-described problems, and provides a method and system for measuring the weight of an individual in real time without being alert.
　より具体的に本発明に係るニワトリの体重測定方法は、シート状圧力センサに乗っているニワトリの足の圧力分布に基づいて前記ニワトリの体重を算出することを特徴とする。 More specifically, the chicken body weight measuring method according to the present invention is characterized in that the body weight of the chicken is calculated based on the pressure distribution of the foot of the chicken riding on the sheet-like pressure sensor.
　また本発明に係る成長監視システムは、
　鶏舎内で育成されるニワトリの育成状態を監視する成長監視システムであって、
上記載のニワトリの体重算出方法に基づいて体重を算出し、一定時間毎に算出した前記ニワトリの体重の平均値を算出する制御器を有することを特徴とする。 Moreover, the growth monitoring system according to the present invention includes:
A growth monitoring system that monitors the breeding status of chickens raised in a poultry house,
It has a controller which calculates a body weight based on the above-described chicken body weight calculation method, and calculates an average value of the body weight of the chickens calculated every predetermined time.
　本発明は、鶏舎の中のニワトリの体重をシート状圧力センサを用いて計測するので、ニワトリが警戒心を起こすことなく、測定をすることができる。 In the present invention, since the weight of the chicken in the poultry house is measured using a sheet-like pressure sensor, the chicken can be measured without being alert.
　また、ニワトリの足の圧力分布を用いるので、ニワトリが静止していれば、片足だけシート状圧力センサ上に乗っていれば、圧力分布を測定し体重を算出することが可能である。 Also, because the pressure distribution of the chicken leg is used, if the chicken is stationary, it is possible to measure the pressure distribution and calculate the weight if only one leg is on the sheet-like pressure sensor.
　また、人間がニワトリを手でサンプリングしながら体重を計測するのではないので、ニワトリにストレスをかけずに、鶏舎中のニワトリの成長を管理することができる。 Also, since humans do not measure the weight while sampling the chicken by hand, it is possible to manage the growth of the chicken in the poultry house without stressing the chicken.

　以下に図面を用いながら、本発明に係る成長監視システムについて説明を行う。なお、以下の説明は本発明の一態様を例示するものであり、本発明に係る成長監視システムは、以下の説明は、本発明の趣旨を逸脱しない範囲で改変することができる。　 The growth monitoring system according to the present invention will be described below with reference to the drawings. The following description exemplifies one aspect of the present invention, and the growth monitoring system according to the present invention can be modified within the scope of the present invention without departing from the gist of the present invention. *
　図１に本発明に係るニワトリの体重測定方法および成長監視システム１の構成を示す。本発明に係る成長監視システム１は、鶏舎内の給餌器や給水器に隣接してシート状圧力センサ１０を設置し、餌や水を摂取しに来たニワトリの体重を計測する。そして計測データの平均値から鶏舎内のニワトリの育成状況を把握するものである。 FIG. 1 shows the structure of a chicken weight measuring method and growth monitoring system 1 according to the present invention. The growth monitoring system 1 according to the present invention installs a sheet-like pressure sensor 10 adjacent to a feeder or water feeder in a poultry house, and measures the weight of a chicken that has come to ingest food or water. And the breeding situation of the chicken in the poultry house is grasped from the average value of the measurement data.
　成長監視システム１は、シート状圧力センサ１０と、制御器２０で構成される。シート状圧力センサ１０は、可撓性のシートの間に圧電素子や歪ゲージといった物理的変形量を電気信号に変換する微小な素子を薄膜状に数多く形成したセンサ部１４と、電子回路１６および通信装置１８を含む。電子回路１６には、ＭＰＵ（Ｍｉｃｒｏ　Ｐｒｏｃｅｓｓｏｒ　Ｕｎｉｔ）といったコンピュータおよびメモリからなる制御部が含まれていても良い。 The growth monitoring system 1 includes a sheet-like pressure sensor 10 and a controller 20. The sheet-like pressure sensor 10 includes a sensor unit 14 in which a large number of minute elements that convert a physical deformation amount such as a piezoelectric element and a strain gauge into an electric signal are formed in a thin film between flexible sheets, an electronic circuit 16, and A communication device 18 is included. The electronic circuit 16 may include a control unit including a computer and a memory such as an MPU (Micro Processor Unit).
　制御器２０は、シート状圧力センサ１０からの信号を受信する通信装置２２とＭＰＵで構成されるコンピュータ２４およびメモリ２６と表示装置およびキーボードといった入出力装置２８で構成される。なお、シート状圧力センサ１０は鶏舎５０内に配置される。 The controller 20 includes a communication device 22 that receives a signal from the sheet-like pressure sensor 10, a computer 24 that includes an MPU, a memory 26, and an input / output device 28 such as a display device and a keyboard. The sheet-like pressure sensor 10 is disposed in the poultry house 50.
　シート状圧力センサ１０は全体として厚みの薄い構造（厚さが１ｃｍ以下程度）であるのが望ましい。鶏舎５０の床面のオガコ等の敷料の中に埋めて使用できるからである。また、敷料の上に直接載置してもよい。 It is desirable that the sheet-like pressure sensor 10 has a thin structure as a whole (thickness is about 1 cm or less). This is because it can be used by being buried in bedding such as sawdust on the floor surface of the poultry house 50. Alternatively, it may be placed directly on the bedding.
　シート状圧力センサ１０は複数のニワトリが乗れる大きさであってもよい。また、鶏舎５０内に複数枚設置してもよい。シート状圧力センサ１０の数が多ければ、計測できる個体数も増え、計測値の精度は向上するからである。 The sheet-shaped pressure sensor 10 may be large enough to carry a plurality of chickens. A plurality of pieces may be installed in the poultry house 50. This is because if the number of the sheet-like pressure sensors 10 is large, the number of individuals that can be measured increases, and the accuracy of the measurement value is improved.
　シート状圧力センサ１０は、制御器２０と通信可能に接続される。通信の方式は限定されない。無線、有線のどちらであってもよい。 The sheet-like pressure sensor 10 is connected to the controller 20 so as to be communicable. The communication method is not limited. Either wireless or wired may be used.
　図２に鶏舎５０内でのシート状圧力センサ１０の設置例を示す。鶏舎５０内には、給餌器５２および給水器５４が配置される。また、ブルーダー（図示せず）が配置されていてもよい。シート状圧力センサ１０は、給餌器５２若しくは給水器５４に隣接して配置されるのが望ましい。ニワトリは、必ず給餌器５２や給水器５４で餌や水を摂取するからである。また、餌や水を摂取する間は、ニワトリは比較的静止しているので、測定がやりやすい。もちろん、これら以外の場所に載置してもよい。 FIG. 2 shows an installation example of the sheet-like pressure sensor 10 in the poultry house 50. In the poultry house 50, a feeder 52 and a water feeder 54 are arranged. Also, a broder (not shown) may be arranged. The sheet-like pressure sensor 10 is desirably disposed adjacent to the feeder 52 or the water feeder 54. This is because chickens always ingest food and water through the feeder 52 and the water feeder 54. In addition, the chicken is relatively stationary during the intake of food and water, so measurement is easy. Of course, you may mount in places other than these.
　なお、短時間に多くのサンプルを得るためには、シート状圧力センサ１０は、給水器５４に隣接して設けるのが望ましい。水を飲む時間の方が餌を食べる時間より短いから、シート状圧力センサ１０上の個体の入れ替わりが頻繁に起こると期待できるからである。 In order to obtain a large number of samples in a short time, the sheet-like pressure sensor 10 is desirably provided adjacent to the water supply 54. This is because the time for drinking water is shorter than the time for eating food, so it can be expected that the replacement of individuals on the sheet-like pressure sensor 10 will occur frequently.
　図３には、シート状圧力センサ１０で得られるセンサ信号Ｇのイメージ像を示す。シート状圧力センサ１０は、微小な圧力素子を可撓性のあるシート上に規則正しく配置し、それぞれの素子の出力を読み出す読み出しラインによって構成されている。そして、各素子からの出力は離散化される。たとえば、１素子につき２５６段階の数値に変換される。 FIG. 3 shows an image of the sensor signal G obtained by the sheet-like pressure sensor 10. The sheet-like pressure sensor 10 is configured by a read line that regularly arranges minute pressure elements on a flexible sheet and reads out the output of each element. And the output from each element is discretized. For example, it is converted into a numerical value of 256 steps per element.
　このシート状圧力センサ１０上にニワトリが乗ると、図３のように足跡の形状に応じたイメージ像が得られる。各イメージは、その点のセンサ素子が感じた圧力に応じた値を色の違いなどで視覚化することができる。もちろん、各センサ素子の出力を数値で得ることもできる。 When a chicken is put on the sheet-like pressure sensor 10, an image corresponding to the shape of the footprint is obtained as shown in FIG. Each image can visualize a value corresponding to the pressure felt by the sensor element at that point by a color difference or the like. Of course, the output of each sensor element can also be obtained numerically.
　ここで、ニワトリの足跡には、体重が最もかかる趾蹠（しせき）９０と指（趾）の跡が見て取れる。左右の足は大きさが同じで対称形状をしている。ニワトリは、４本の指（趾）を持ち、体の斜め後方（後方は尾のある方向）に向かって所謂親指に当たる第１趾９１が備わっている。そして体の前方（頭のある方向）に、この第１趾９１のある側から第２趾９２、第３趾９３、第４趾９４が、扇方に配置されている。この中では、第３趾９３が最も長い。したがって、最も長い第３趾９３の方向が同じ方向を向いている足跡同士が１つの個体の足と判断できる。 Here, you can see the traces of the sushi 90 and the finger (s) that take the most weight on the chicken footprint. The left and right feet are the same size and symmetrical. The chicken has four fingers (roosters) and is provided with a first rod 91 that hits the so-called thumb toward the back of the body (the rear is the direction with the tail). Then, in front of the body (in the direction with the head), the second rod 92, the third rod 93, and the fourth rod 94 are arranged in the fan direction from the side where the first rod 91 is located. Among these, the third rod 93 is the longest. Therefore, it can be determined that the footprints in which the longest third heel 93 is directed in the same direction are the feet of one individual.
　１つの個体は通常両足に均等に全体重を乗せているので、両足の圧力値から求められる荷重を全て合計するとニワトリの全体重が求められる。また、ニワトリが静止していれば、片方の足の荷重からニワトリの全体重を推定することができる。　 Since one individual usually puts the total weight evenly on both legs, the total weight of the chicken is calculated by adding all the loads determined from the pressure values of both legs. If the chicken is stationary, the total weight of the chicken can be estimated from the load on one leg. *
　図４には、本発明の成長監視システムが行うニワトリの体重測定に係る動作のフローについて説明する。測定したデータを集計する処理フローは別途後述する。このフローは、制御器２０が行っても良いし、シート状圧力センサ１０の電子回路１６が行っても良い。どちらで行っても、成長監視システム１の制御器２０が行ったとしてよい。 FIG. 4 explains the flow of the operation related to the weight measurement of the chicken performed by the growth monitoring system of the present invention. A processing flow for collecting the measured data will be described later. This flow may be performed by the controller 20 or the electronic circuit 16 of the sheet-like pressure sensor 10. Whichever is performed, the controller 20 of the growth monitoring system 1 may be performed.
　また、図５には、シート状圧力センサ１０のデータが処理される様子を示す。なお、以下では１枚のシート状圧力センサ１０を用いた場合について説明するが、制御器２０が、複数のシート状圧力センサ１０について処理をするようにしてもよい。 FIG. 5 shows how the data of the sheet-like pressure sensor 10 is processed. In addition, although the case where one sheet-like pressure sensor 10 is used will be described below, the controller 20 may process a plurality of sheet-like pressure sensors 10.
　まず、簡単に成長監視システムの処理を説明しておく。鶏舎５０にはシート状圧力センサ１０が配置してある。このシート状圧力センサ１０上に乗ったニワトリの足裏の圧力分布をシート状圧力センサ１０は検知することができる。 First, let us briefly explain the processing of the growth monitoring system. A sheet-like pressure sensor 10 is arranged in the poultry house 50. The sheet-like pressure sensor 10 can detect the pressure distribution of the soles of chickens on the sheet-like pressure sensor 10.
　このニワトリの足裏の圧力分布に基づいて、ニワトリの体重を算出する。これを定期的に行うことで、多くのニワトリの体重を測定することができ、鶏舎５０で飼育されているニワトリ全体の育成の程度を統計的に推定することができる。 * Based on the pressure distribution on the sole of the chicken, the weight of the chicken is calculated. By performing this periodically, the weight of many chickens can be measured, and the degree of breeding of the whole chicken raised in the poultry house 50 can be statistically estimated.
　特に、シート状圧力センサ１０を用いると、複数のニワトリの体重を一度に測定することができる。また、片足だけをシート状圧力センサ１０に乗せていても体重を算出することができる。 Particularly, when the sheet-like pressure sensor 10 is used, the weights of a plurality of chickens can be measured at a time. Further, the weight can be calculated even when only one leg is placed on the sheet-like pressure sensor 10.
　図４を参照して、シート状圧力センサ１０は、動作を開始すると（ステップＳ１００）、終了処理を判定する（ステップＳ１０２）。終了処理の判断は、特に限定されないが、電源のＯＦＦや、制御器２０からの指示などが挙げられる。終了する場合（ステップＳ１０２のＹ分岐）は、停止する（ステップＳ１３０）。 Referring to FIG. 4, when the sheet-shaped pressure sensor 10 starts operating (step S100), it determines an end process (step S102). The determination of the termination process is not particularly limited, and examples include power-off and an instruction from the controller 20. When the process ends (Y branch in step S102), the process stops (step S130).
　継続する場合（ステップＳ１０２のＮ分岐）は、現在のシート状圧力センサ１０の各画素に対応する全データＧ０を記憶する（ステップＳ１０４）。全データＧ０とは、図５（ａ）に示すデータで、シート状圧力センサ１０の全面から得られるデータである。次に規定時間（ΔＴ）だけ遅れた時刻のシート状圧力センサ１０の全データＧ１を記憶する（ステップＳ１０６）。規定時間は数秒程度の短い時間であってよい。 When continuing (N branch of step S102), all the data G0 corresponding to each pixel of the present sheet-like pressure sensor 10 are memorize | stored (step S104). The total data G0 is data shown in FIG. 5A and is obtained from the entire surface of the sheet-like pressure sensor 10. Next, all the data G1 of the sheet-like pressure sensor 10 at the time delayed by the specified time (ΔT) is stored (step S106). The specified time may be as short as several seconds.
　次に全データＧ０と全データＧ１を比較し、同じか否かを判断する（ステップＳ１０８）。比較の方法は特に限定されるものではない。全データＧ０の総和と全データＧ１の総和を比較しても良い。ここで「ε」はシート状圧力センサ１０上に静止していたニワトリがいるか否かを判断するための閾値である。例えば、全データＧ１と全データＧ０にほとんど変化がなければ、規定時間の間ニワトリはシート状圧力センサ１０上に静止していたと考えてよく、次のステップに移行する（ステップＳ１０８のＹ分岐）。 Next, all data G0 and all data G1 are compared to determine whether or not they are the same (step S108). The comparison method is not particularly limited. The total sum of all data G0 and the total sum of all data G1 may be compared. Here, “ε” is a threshold value for determining whether or not there is a stationary chicken on the sheet-like pressure sensor 10. For example, if there is almost no change in all data G1 and all data G0, it may be considered that the chicken has been stationary on the sheet-like pressure sensor 10 for a specified time, and the process proceeds to the next step (Y branch of step S108). .
　また、規定時間の後、片足分だけの荷重が減っていたとすると、１羽が移動した若しくは移動中であったと考えられる。そのような場合は、静止していたニワトリだけの体重を算出することができるので、全データＧ１に基づく算出処理に移ると判断してもよい。視閾値「ε」はそのような判断をするための閾値といえる。したがって、「ε」は、ニワトリの成長および、シート状圧力センサ１０の大きさに従って変更されてもよい。 Also, if the load for one foot has decreased after the specified time, it is considered that one wing has moved or was moving. In such a case, the weight of only the chicken that has been stationary can be calculated, so it may be determined that the calculation process is to be based on all data G1. The visual threshold “ε” can be said to be a threshold for making such a determination. Therefore, “ε” may be changed according to the growth of the chicken and the size of the sheet-like pressure sensor 10.
　全データＧ０と全データＧ１が大きく変化している場合は、改めて、全データＧ０の取得から始める（ステップＳ１０８のＮ分岐）。　 When all the data G0 and all the data G1 have changed greatly, the process starts again with the acquisition of all the data G0 (N branch in step S108). *
　次に全データＧ１に基づくニワトリの体重の算出処理に移る。まず、全データＧ１の中で１つの足のデータＤｓを確定させる（ステップＳ１１０）。具体例を示すと、全データＧ１の中で、規定の値Ｗｔｈ以上の値が集合している箇所を見つける。これはニワトリの足の裏で最も体重が乗る趾蹠９０の部分を検出する。 Next, the process of calculating the chicken weight based on all data G1 is started. First, the data Ds for one leg among all the data G1 is determined (step S110). As a specific example, a location where values equal to or greater than a specified value Wth are found in all the data G1. This detects the portion of the heel 90 that weighs most on the soles of the chicken's feet.
　ここで、規定の値Ｗｔｈは、ニワトリの日齢によって日々刻々と変化するものである。前日までに計測値から求めた値であってもよいし、予めある日齢の規定値をきめておいてもよい。　 Here, the specified value Wth changes every day depending on the age of the chicken. It may be a value obtained from the measured value until the previous day, or a predetermined value for a certain age may be determined in advance. *
　次に１つの趾蹠９０から延びる趾を検出する。そして、片足のデータＤｓとしてまとめる。例えば、図５（ａ）を参照して、丸Ａで囲んだ部分はあるニワトリの左足に相当する。したがって、この丸Ａで囲まれたデータは、１つの足のデータＤｓとしてまとめて扱えるようにする。これはニワトリの足の圧力分布Ｄｓともいえる。 Next, the ridge extending from one ridge 90 is detected. Then, the data is collected as one-leg data Ds. For example, referring to FIG. 5A, a portion surrounded by a circle A corresponds to the left foot of a chicken. Therefore, the data surrounded by the circle A can be handled collectively as one leg data Ds. This can be said to be the pressure distribution Ds of the chicken leg.
　なお、足の圧力分布Ｄｓを求める際には、趾も確定させる。ニワトリの足では、趾は、趾蹠９０を中心としてほぼ直線状に延びる。そしてその中でもっとも長い趾が第３趾９３である。趾蹠９０と第３趾９３を結ぶ方向がこの足の個体が向いている方向である。図５（ａ）では、大きな矢印で各個体の向きを示した。 In addition, when obtaining the pressure distribution Ds of the foot, the heel is also determined. In the chicken leg, the heel extends substantially linearly around the heel 90. And the longest kite among them is the third kite 93. The direction connecting the heel 90 and the third heel 93 is the direction in which the individual leg is facing. In FIG. 5A, the direction of each individual is indicated by a large arrow.
　この方向から直角方向で第１趾９１がある側の他の趾蹠が同じ個体の他の足である。例えば、図５の例でいうと、丸Ａで囲った足跡では趾蹠９０ａと第３趾９３ａの方向が直線Ｌ１である。この直線Ｌ１の方向にある最も近い趾蹠は符号９０ｂである。したがって、丸Ａで囲ったデータＤｓｘと丸Ｂで囲ったデータＤｓｙは同じ個体の左右の足跡ということになる。 The other heel on the side with the first heel 91 in the direction perpendicular to this direction is the other leg of the same individual. For example, in the example of FIG. 5, in the footprint surrounded by the circle A, the direction of the heel 90a and the third heel 93a is a straight line L1. The nearest ridge in the direction of the straight line L1 is 90b. Therefore, the data Dsx surrounded by the circle A and the data Dsy surrounded by the circle B are the left and right footprints of the same individual.
　このようにして、対になる足のデータを決める。対になる足のデータの有無は、足の圧力分布Ｄｓに情報として付加される。対になる足が存在しない場合もある。シート状圧力センサ１０上に片足だけ乗せていたニワトリがいた場合である。図５（ａ）では、丸Ｃで囲んだ足跡である。 In this way, the paired foot data is determined. The presence / absence of paired foot data is added as information to the foot pressure distribution Ds. There may be no pair of feet. This is a case where there is a chicken on one sheet of the pressure sensor 10. In FIG. 5A, the footprint is surrounded by a circle C.
　全データＧ１中の全ての足の圧力分布Ｄｓが確定したら、各圧力分布Ｄｓに番号を付ける。ここではｋ番目の足の圧力分布Ｄｓを「Ｄｓｋ」と表す。図５（ｂ）では、左から順にｋ＝１、・・・、ｋ＝５と番号付けされた状態を示す。そして、カウント用の変数ｋを１に設定する（ステップＳ１１０）。 When the pressure distributions Ds of all the feet in all the data G1 are determined, each pressure distribution Ds is numbered. Here, the pressure distribution Ds of the k-th foot is represented as “Dsk”. FIG. 5B shows a state numbered k = 1,..., K = 5 sequentially from the left. Then, the count variable k is set to 1 (step S110).
　次にこれらの足の圧力分布Ｄｓｋの圧力値の合計を求め、重さＷｋに換算する（ステップＳ１１６）。そして、求めた重さＷｋを２倍すれば、１羽のニワトリの体重Ｗｇを求めることができる。 Next, the sum of the pressure values of these foot pressure distributions Dsk is obtained and converted into a weight Wk (step S116). Then, if the calculated weight Wk is doubled, the weight Wg of one chicken can be determined.
　ステップＳ１１２では、全ての足の圧力分布データＤｓｋについて重さへの変換が完了したか否かを判断する。できていない場合は、次のフローに移る（ステップＳ１１２のＮ分岐）。全てのデータＤｓｋについて換算が終了したら（ステップＳ１１２のＹ分岐）、全データＤ１を記録した時刻と、算出した体重Ｗｋを記録する（ステップＳ１２０）。そして、再び終了処理（ステップＳ１０２）まで戻り、処理を継続させる。 In step S112, it is determined whether the pressure distribution data Dsk of all feet has been converted to weight. If not, the process proceeds to the next flow (N branch in step S112). When conversion has been completed for all data Dsk (Y branch in step S112), the time when all data D1 was recorded and the calculated weight Wk are recorded (step S120). Then, the process returns again to the end process (step S102), and the process is continued.
　次にステップＳ１１４では、今処理対象としている足の圧力分布データＤｓｋにはまだ重さへの換算を終えていない対の足のデータがあるか否かを調べる（ステップＳ１１４）。ない場合（ステップＳ１１４のＮ分岐）は、足の圧力分布データＤｓｋを重さＷｋに換算する（ステップＳ１１６）。そして、カウント変数ｋをインクリメントしてステップＳ１１２に戻る。 Next, in step S114, it is checked whether or not there is paired foot data that has not yet been converted into weight in the foot pressure distribution data Dsk that is currently processed (step S114). If not (N branch in step S114), the foot pressure distribution data Dsk is converted into the weight Wk (step S116). Then, the count variable k is incremented and the process returns to step S112.
　すでに換算した足の対がある場合（ステップＳ１１４のＹ分岐）は、その足跡は、重さ換算せずに、カウント変数ｋのインクリメントを行う（ステップＳ１１８）。結果、図５（ｂ）では、Ｄｓ１、Ｄｓ２、Ｄｓ４が重さＷ１、Ｗ２、Ｗ４を経て（Ｗｋを２倍して）、体重Ｗｇ１、Ｗｇ２、Ｗｇ４へと変換される。なお、両方の足の圧力分布Ｄｓｋがわかる場合は、両方の足の圧力分布Ｄｓｋの全ての圧力値の総和を求め、体重Ｗに換算してもよい。 If there is a converted pair of feet (Y branch of step S114), the footprint is incremented without counting the weight (step S118). As a result, in FIG. 5B, Ds1, Ds2, and Ds4 are converted to weights Wg1, Wg2, and Wg4 via weights W1, W2, and W4 (double Wk). When the pressure distribution Dsk of both feet is known, the sum of all pressure values of the pressure distribution Dsk of both feet may be obtained and converted to the weight W.
　次に体重Ｗの処理について説明する。図６には、体重データの処理フローを示す。制御器２０は、処理がスタートしたら（ステップＳ２００）、終了処理を行う（ステップＳ２０２）。終了処理は、システム全体の電源Ｏｆｆや、停止指示があった場合などで、特に限定されるものではない。 Next, the process of weight W will be described. FIG. 6 shows a processing flow of weight data. When the process starts (step S200), the controller 20 performs an end process (step S202). The termination process is not particularly limited, for example, when the entire system is turned off or a stop instruction is issued.
　終了する場合（ステップＳ２０２のＹ分岐）は、システム全体を停止させる（ステップＳ２３０）。継続する場合（ステップＳ２０２のＮ分岐）は、各シート状圧力センサ１０からの通信の有無を確認する（ステップＳ２０４）。通信があった場合（ステップＳ２０４のＹ分岐）は、通信があった各シート状圧力センサ１０の識別番号ＩＤと、送信されてきた計量値Ｗｇのデータを得る（ステップＳ２０６）。 When the process ends (Y branch in step S202), the entire system is stopped (step S230). When continuing (N branch of step S202), the presence or absence of communication from each sheet-like pressure sensor 10 is confirmed (step S204). When there is communication (Y branch of step S204), the identification number ID of each sheet-like pressure sensor 10 with which communication has been made and the data of the transmitted weight value Wg are obtained (step S206).
　そして、受信時刻Ｔと共に記録する（ステップＳ２０８）。なお、受信時刻Ｔは、シート状圧力センサ１０が制御器２０に送信してもよいし、制御器２０が自分の内部時計に基づいて付加してもよい。シート状圧力センサ１０からの通信がない場合（ステップＳ２０４のＮ分岐）は、通信があるまで待機する。計量値Ｗｇ等の記録が終わったら、終了処理（ステップＳ２０２）に戻る。 Then, it is recorded together with the reception time T (step S208). The reception time T may be transmitted by the sheet-like pressure sensor 10 to the controller 20 or may be added by the controller 20 based on its own internal clock. When there is no communication from the sheet-like pressure sensor 10 (N branch of step S204), it waits until there is communication. When the recording of the measurement value Wg and the like is completed, the process returns to the end process (step S202).
　制御器２０は、複数のシート状圧力センサ１０からの計量値Ｗｇを受信し続けると共に、一定時間毎に（ステップＳ２１０）計量値Ｗｇの統計データ（平均値等）を算出する（ステップＳ２１２）。一定時間とは、特に限定されないが、ニワトリ特にブロイラーは１日で１００ｇ以上成長する場合もある。したがって、少なくとも２４時間毎の平均値を算出するのが望ましい。また、入出力装置２８からの指示により、入雛時からの成長に関するデータを日ごとに表示しても良い。 The controller 20 continues to receive the measured values Wg from the plurality of sheet-like pressure sensors 10 and calculates statistical data (average value, etc.) of the measured values Wg at regular time intervals (Step S210) (Step S212). Although it is not specifically limited with a fixed time, A chicken, especially a broiler may grow 100g or more in one day. Therefore, it is desirable to calculate an average value at least every 24 hours. In addition, according to an instruction from the input / output device 28, data related to growth from the time of entry may be displayed for each day.
　また、あまり短い時間間隔で計量値の平均を算出しても、意味のあるデータとして読みにくい。平均値の算出は５分以上の間隔をあけるのが望ましい。１時間毎の平均値を算出するのが鶏舎中のニワトリの全体の成長の程度を把握しやすい。 Also, even if the average of the measured values is calculated at a very short time interval, it is difficult to read as meaningful data. It is desirable that the average value be calculated with an interval of 5 minutes or more. It is easy to grasp the degree of growth of the whole chicken in the poultry house by calculating the average value every hour.
　以上のように、本発明に係る成長監視システムは、水や餌を摂取しにきたニワトリの体重を常に測定するので、鶏舎内に多く設置することで、多くのニワトリの体重を計測することができ、鶏舎内のニワトリの育成状態を日齢毎の体重の増加として見る事が出来る。したがって、成長率が低下した場合は、直ちに対策を講じることができる。 As described above, since the growth monitoring system according to the present invention always measures the weight of chickens that have taken in water and food, it is possible to measure the weights of many chickens by installing many in the poultry house. Yes, you can see the breeding status of chickens in the poultry house as weight gain for each age. Therefore, if the growth rate falls, measures can be taken immediately.
　本発明は成長の程度を体重で管理するブロイラーの育成には最も好適に利用することができるが、レイヤーやその他の家禽類の成長監視にも好適に利用することができる。 The present invention can be most suitably used for breeding broilers that manage the degree of growth by weight, but can also be suitably used for growth monitoring of layers and other poultry.
