Abstract
Description
本発明は、研究施設、工場、病院など、作業者の安全や製造物に対して危険を伴う環境において、発生する有毒ガス等を局所排気するヒュームフードに関するものであり、特に作業者の安全に関わるデータを取得して安全な作業環境かどうかを判断するヒュームフード管理システムに関するものである。 The present invention relates to a fume hood that locally exhausts toxic gas generated in laboratories such as research facilities, factories, hospitals, etc. in environments where there is a danger to the safety of workers or products, and in particular to the safety of workers. The present invention relates to a fume hood management system that obtains related data and determines whether or not the work environment is safe.
化学実験では、実験作業過程において、人体に有害なガスや粉塵等が発生する場合が多い。これら有害物質の室内への拡散を防止し、人体への汚染を防ぐ装置の１つにヒュームフードがある。一般に、ヒュームフードは、上下または左右に開閉可能なサッシドア付きの囲い（エンクロージャ）を備えており、実験室の作業者はこのサッシドアからエンクロージャ内にアクセスすることができる。ヒュームフードで作業中の作業者が有害なガスや粉塵等に曝されないようにするために、エンクロージャは有害物質を除去する排気装置に接続されている。 In chemical experiments, gases and dusts that are harmful to the human body are often generated in the course of experimental work. A fume hood is one of devices that prevent the diffusion of these harmful substances into the room and prevent contamination of the human body. In general, the fume hood is provided with an enclosure (enclosure) with a sash door that can be opened and closed vertically or horizontally, and a laboratory worker can access the enclosure from the sash door. To prevent workers working in the fume hood from being exposed to harmful gases, dust, etc., the enclosure is connected to an exhaust system that removes harmful substances.
従来、ヒュームフードを管理するヒュームフード管理システムでは、小規模な給排気設備で多くのヒュームフードを設置することを目的として、ダイバーシティ（同時利用率）という思想を給排気設備設計に用いている。ダイバーシティとは、個別実験装置の最大性能の合算値よりも小さい容量で設備を設計することである。ダイバーシティを用いた設計の利点は前述のとおり、小規模な給排気設備で多くのヒュームフードを設置できることである。その半面、欠点として想定した同時利用率を上回って使用された場合、設備容量を超え、安全な使用環境を損なう可能性があった。 Conventionally, in a fume hood management system for managing a fume hood, the idea of diversity (simultaneous utilization) is used in the design of a supply / exhaust facility for the purpose of installing a large number of fume hoods with a small supply / exhaust facility. Diversity is the design of equipment with a capacity smaller than the sum of the maximum performances of the individual experimental devices. As described above, the advantage of the design using diversity is that a large number of fume hoods can be installed in a small-scale air supply / exhaust system. On the other hand, when it is used in excess of the simultaneous utilization rate assumed as a defect, there is a possibility that the facility capacity will be exceeded and the safe use environment may be impaired.
そこで、従来のヒュームフード管理システムでは、各ヒュームフードから稼動状態を示すデータを収集し、このデータに基づいて利用中のヒュームフードの同時利用台数を算出し、この同時利用台数をヒュームフードの全台数で割った同時利用率を演算し、この同時利用率を実績値として表示するようにしていた（特許文献１参照）。また、特許文献１に開示されたヒュームフード管理システムでは、複数のヒュームフードが接続された排気系統によって排出可能な最大の排気風量である設計最大排気風量と稼動状態のヒュームフードの瞬時排気風量の総和である最大排気風量との差を安全マージンとし、最大排気風量と安全マージンの実績値を表示するようにしていた。 Therefore, in the conventional fume hood management system, data indicating the operating state is collected from each fume hood, the number of simultaneous use of the fume hood is calculated based on this data, and this number of simultaneous use is calculated for all the fume hoods. The simultaneous usage rate divided by the number of units was calculated, and this simultaneous usage rate was displayed as an actual value (see Patent Document 1). Further, in the fume hood management system disclosed in Patent Document 1, the design maximum exhaust air volume that is the maximum exhaust air volume that can be discharged by an exhaust system to which a plurality of fume hoods are connected and the instantaneous exhaust air volume of the operating fume hood are determined. The difference between the maximum exhaust air volume, which is the sum, is used as the safety margin, and the actual exhaust air volume and the actual margin value are displayed.
特許文献１に開示されたヒュームフード管理システムでは、同時利用率、最大排気風量、安全マージンといった情報を表示している。しかしながら、これらの情報は、給排気設備設計が妥当かどうかの判断データとして使用したり、設備改修時の基礎データとして使用したりすることも想定されているため、ヒュームフードを使用する作業者にとっては理解し難く、危険が迫っているのかもう少し余裕があるのかを作業者が即座に理解し難いという問題点があった。 In the fume hood management system disclosed in Patent Document 1, information such as the simultaneous utilization rate, the maximum exhaust air volume, and the safety margin is displayed. However, this information is also assumed to be used as judgment data for determining whether the design of the supply and exhaust facilities is appropriate, or as basic data for equipment renovation. Is difficult to understand, and it is difficult for the operator to immediately understand whether the danger is imminent or a little more.
本発明は、上記課題を解決するためになされたもので、ヒュームフードを使用する作業者に危険が迫っていることを瞬時に通報することができるヒュームフード管理システムおよび管理方法を提供することを目的とする。 The present invention has been made to solve the above-described problem, and provides a fume hood management system and a management method capable of instantaneously reporting that a worker using a fume hood is in danger.

Hereinafter, the operation of the fume hood management system will be described. FIG. 3 is a flowchart showing the operation of the
各排気バルブコントローラ２のデータ収集部２０は、それぞれ対応するヒュームフード１から稼働状態を示すデータを定期的に収集する（図３ステップＳ１００）。データは、瞬時排気風量のみの場合、瞬時排気風量とサッシ開度とからなる場合、瞬時排気風量とサッシ開度と人検知センサの検知結果（作業者の在／不在）とからなる場合などがあり、ヒュームフード１の形式によって収集可能なデータが異なる。データ収集部２０が収集したデータは、データ記憶部２１に格納される（ステップＳ１０１）。

Subsequently, the
警報通知部３３は、演算部３２が算出した瞬時排気風量の合計値と予め想定される排気風量の最大値である最大排気風量とを比較する（ステップＳ２０３）。最大排気風量は、排気系統７によって排出可能な排気風量の限界値を若干下回る値に設定されており、瞬時排気風量の合計値が最大排気風量を超えたとしても、作業者にとって直ぐに危険な状態にはならない値に予め設定されている。
The
警報通知部３３は、演算部３２が算出した瞬時排気風量の合計値が最大排気風量を超える場合（ステップＳ２０３においてＹＥＳ）、警報が発生したと判定し、警報送信部３４を通じて各排気バルブコントローラ２へ警報通知信号を送信する（ステップＳ２０４）。また、警報通知部３３は、排気バルブコントローラ２への警報通知後に、瞬時排気風量の合計値が最大排気風量以下になった場合（ステップＳ２０５においてＹＥＳ）、警報発生状態から正常状態に復旧したと判定し、警報送信部３４を通じて各排気バルブコントローラ２へ復旧通知信号を送信する（ステップＳ２０６）。こうして、ステップＳ２００〜Ｓ２０６の処理が繰り返し実行される。

各排気バルブコントローラ２の警報受信部２４は、ステップＳ１０４において監視装置３から警報通知信号を受信した場合、警報通知信号を警報出力部２５に渡す。警報通知信号を受信した警報出力部２５は、各排気バルブコントローラ２に接続されているヒュームフードモニター（不図示）を通じて、各ヒュームフード１を使用する作業者に警報が発生したことを通知する（ステップＳ１０５）。このときのヒュームフードモニターによる通知の例としては、例えばブザーや音声による通知やランプ点灯による通知などがある。
The
また、各排気バルブコントローラ２の警報受信部２４は、ステップＳ１０４において監視装置３から復旧通知信号を受信した場合、復旧通知信号を警報出力部２５に渡す。復旧通知信号を受信した警報出力部２５は、各排気バルブコントローラ２に接続されているヒュームフードモニターを通じて、各ヒュームフード１を使用する作業者に正常状態に復旧したことを通知する（ステップＳ１０５）。このときのヒュームフードモニターによる通知の例としては、例えばブザーや音声による通知やランプ消灯による通知などがある。
各排気バルブコントローラ２と監視装置３とは、ヒュームフード管理システムの動作が停止するまで（ステップＳ１０６，Ｓ２０７においてＹＥＳ）、図３、図４に示した処理を行う。

Since it was made to do, it can notify the operator who uses each fume hood 1 that danger is imminent. In the present embodiment, when a work can be performed within a safe range where a plurality of fume hoods 1 are used simultaneously, an alarm is not generated, so that the worker can work in a safe and stress-free environment.

Since the alarm is notified when the value exceeds a predetermined threshold, it is possible to notify the worker using each fume hood 1 that the danger is imminent.
また、本実施の形態では、作業者に負荷率のデータを通知するようにしたので、作業者が事前にまたは作業中に設備の負荷状況を知ることができる。その結果、負荷率のデータを見た作業者がヒュームフードの使用を見送るといった自己抑制を期待できるので、ヒュームフードの使用者が次々と増えて設備の負荷が限界に近づくといった危険性を回避することができ、安全な環境を作業者に提供することができる。 In the present embodiment, since the load factor data is notified to the worker, the worker can know the load status of the facility in advance or during the work. As a result, it is possible to expect self-suppression that workers who look at the load factor data forego the use of the fume hood, thereby avoiding the danger that the number of fume hood users will increase one after another and the load on the equipment will approach the limit. It is possible to provide a safe environment to workers.
なお、第１、第２の実施の形態では、各排気バルブコントローラ２がヒュームフード１からデータを定期的に収集して監視装置３へ送信しているが、これに限るものではなく、ヒュームフード１の瞬時排気風量に変化が発生した場合に、この瞬時排気風量のデータを収集して監視装置３へ送信するようにしてもよい。

また、警報通知と復旧通知を繰り返すハンチングを防止するため、所定時間以上の間、瞬時排気風量の合計値が最大排気風量を超えているとき（第１の実施の形態の場合）、あるいは所定時間以上の間、負荷率が閾値を超えているときに（第２の実施の形態の場合）、警報発生と判断するようにしてもよい。 Further, in order to prevent hunting that repeats the alarm notification and the recovery notification, when the total value of the instantaneous exhaust airflow exceeds the maximum exhaust airflow for a predetermined time or more (in the case of the first embodiment), or for a predetermined time During the above, when the load factor exceeds the threshold value (in the case of the second embodiment), it may be determined that an alarm has occurred.
なお、第１、第２の実施の形態において排気バルブコントローラ２と監視装置３の各々は、それぞれＣＰＵ、メモリおよびインタフェースを備えたコンピュータとこれらのハードウェア資源を制御するプログラムによって実現することができる。排気バルブコントローラ２と監視装置３の各々のＣＰＵは、メモリに格納されたプログラムに従って第１、第２の実施の形態で説明した処理を実行する。
In the first and second embodiments, each of the
