　要求信号を受信した空気調和負荷装置１は自身が保有する吸い込み温度データを含む信号を通信線４００を介して集中管理装置２００に送信する（以下、要求信号に応じて、他の装置に送る各種データを含む信号を応答信号という）。要求信号等を含む通信線４００に流す信号については、送信に際し、例えば図７（ｂ）に示すように、プロトコル等に基づいてあらかじめ設定した通信フレームに則した形式で信号を送る。通信フレームは、例えば、送信元アドレス、送信先アドレス、通信コマンドの電文長等のデータを含むヘッダー部Ａと、通信コマンド部Ｂと、伝送エラーを検出するコード等を含むフレームチェック部Ｃとで構成される。さらに、通信コマンド部Ｂは制御監視の動作内容や対象の分類を示す通信コマンド分類部Ｂ１、制御監視の動作内容を表す動作内容部Ｂ２及び制御監視の動作対象を表す動作の対象部Ｂ３等で構成される。 The air conditioning load device 1 that has received the request signal transmits a signal including the suction temperature data held by itself to the central control device 200 via the communication line 400 (hereinafter, various types of signals sent to other devices in response to the request signal). A signal containing data is called a response signal). As for a signal to be sent to the communication line 400 including a request signal, the signal is transmitted in a format conforming to a communication frame set in advance based on a protocol or the like, for example, as shown in FIG. The communication frame includes, for example, a header part A including data such as a transmission source address, a transmission destination address, and a communication command message length, a communication command part B, and a frame check part C including a code for detecting a transmission error. Composed. Further, the communication command part B includes a communication command classifying part B1 indicating the control monitoring operation contents and target classification, an operation content part B2 indicating the control monitoring action contents, an action target part B3 indicating the control monitoring action object, and the like. Composed.
　集中管理装置２００は空気調和負荷装置１から吸い込み温度データを含む信号を受信して吸い込み温度データを取得する。 The centralized management device 200 receives the signal including the suction temperature data from the air conditioning load device 1 and acquires the suction temperature data.
　前述したように、リモートコントローラ装置１００ａ、１００ｂも空気調和負荷装置１の吸い込み温度データを必要とする。信号の送信先がいずれの装置であっても、通信線４００に送られた信号はリモートコントローラ装置１００ａ、１００ｂにも送られる。そこで、受信した信号に基づき、リモートコントローラ装置１００ａ、１００ｂは、送信元アドレス及び通信コマンドを判断する。そして、送信元アドレスが空気調和負荷装置１を表すものであり、通信コマンドが吸い込み温度データの要求信号に対するものと判断すると、信号を受信して処理を行い、吸い込み温度データを取得する。 As described above, the remote controller devices 100a and 100b also require the suction temperature data of the air conditioning load device 1. Regardless of the signal transmission destination, the signal sent to the communication line 400 is also sent to the remote controller devices 100a and 100b. Therefore, based on the received signal, the remote controller devices 100a and 100b determine the transmission source address and the communication command. When the transmission source address represents the air conditioning load device 1 and the communication command is determined to be for the suction temperature data request signal, the signal is received and processed to acquire the suction temperature data.
　ここで、本実施の形態１では、集中管理装置２００が要求信号を送信し、リモートコントローラ装置１００ａ、１００ｂが送信元アドレスと通信コマンドとに基づいて、吸い込み温度データを取得するものとしたが、これに限定するものではない。例えばリモートコントローラ装置１００ａが送信した要求信号に対する信号に基づいて、リモートコントローラ装置１００ｂと集中管理装置２００とが吸い込み温度データを取得するようにしてもよい。 Here, in the first embodiment, the centralized management device 200 transmits a request signal, and the remote controller devices 100a and 100b acquire the suction temperature data based on the transmission source address and the communication command. However, the present invention is not limited to this. For example, the remote controller device 100b and the centralized management device 200 may acquire the suction temperature data based on a request signal transmitted from the remote controller device 100a.
　また、本実施の形態では、リモートコントローラ装置１００が吸い込み温度データを取得するようにしたが、これに限定するものではない。空気調和装置において通信線４００に通信接続する装置（機器）であれば、他の装置において吸い込み温度データを取得するようにしてもよい。 In the present embodiment, the remote controller device 100 acquires the suction temperature data, but the present invention is not limited to this. As long as it is a device (apparatus) that is communicably connected to the communication line 400 in the air conditioner, the suction temperature data may be acquired in another device.
　本実施の形態では、リモートコントローラ装置１００は、吸い込み温度データを取得しているが、これに限定するものではない。吸い込み温度データに限らず、リモートコントローラ装置が必要とするデータを取得するようにすることができる。このとき、リモートコントローラ装置１００は、信号中の送信元アドレスと通信コマンドに基づいて、有用なデータかどうかを判断する。 In the present embodiment, the remote controller device 100 acquires the suction temperature data, but the present invention is not limited to this. Not only the suction temperature data but also the data required by the remote controller device can be acquired. At this time, the remote controller device 100 determines whether the data is useful based on the transmission source address and the communication command in the signal.
　以上のように、実施の形態１の空気調和装置の通信システムによれば、空気調和負荷装置１から集中管理装置２００への信号等、通信線４００（ネットワーク）に流れる信号を、リモートコントローラ装置１００ａ、１００ｂが受信し、信号中の送信元アドレスと通信コマンドに基づいて、信号中の吸い込み温度データを取得するようにしたので、リモートコントローラ装置１００が要求信号を送信しなくても、吸い込み温度データを取得することができる。また、要求信号毎に空気調和負荷装置１から信号を送る必要がないので、システム全体の通信トラフィックを低減することができる。 As described above, according to the communication system of the air conditioning apparatus of the first embodiment, a signal that flows through the communication line 400 (network), such as a signal from the air conditioning load apparatus 1 to the centralized management apparatus 200, is transmitted to the remote controller apparatus 100a. , 100b receives the suction temperature data in the signal based on the transmission source address and the communication command in the signal, so that the suction temperature data can be obtained even if the remote controller device 100 does not transmit the request signal. Can be obtained. Moreover, since it is not necessary to send a signal from the air conditioning load device 1 for each request signal, the communication traffic of the entire system can be reduced.
実施の形態２．
　図８は本発明の実施の形態２に係る装置間の通信を説明するための図である。図８では、空気調和負荷装置１は集中管理装置２００ａ、２００ｂ、リモートコントローラ装置１００ａ、１００ｂと通信線４００で接続されている。ここで、本実施の形態の集中管理装置２００ｂは、集中管理装置２００ａとは異なる場所で空気調和負荷装置１を監視・操作する装置である。そして、集中管理装置２００ｂは集中管理装置２００ａと同じデータを保有するようにしている。 Embodiment 2. FIG.
FIG. 8 is a diagram for explaining communication between apparatuses according to Embodiment 2 of the present invention. In FIG. 8, the air conditioning load device 1 is connected to the centralized management devices 200 a and 200 b and the remote controller devices 100 a and 100 b via the communication line 400. Here, the centralized management device 200b of the present embodiment is a device that monitors and operates the air-conditioning load device 1 at a place different from the centralized management device 200a. The central management apparatus 200b holds the same data as the central management apparatus 200a.
　集中管理装置２００ａは、空気調和負荷装置１に対して、例えば、吸い込み温度、空気調和負荷装置の運転状態等の各種データを含む信号の送信を要求する信号（要求信号）を通信線４００を介して送信する。 The centralized management device 200a sends a signal (request signal) for requesting the air-conditioning load device 1 to transmit a signal including various data such as the suction temperature and the operating state of the air-conditioning load device via the communication line 400. To send.
　要求信号を受信した空気調和負荷装置１は自身が保有するデータを含む信号を通信線４００を介して集中管理装置２００ａに送信する。送信に際し、あらかじめ設定した通信フレームに則した形式の信号が送られる。集中管理装置２００ａは空気調和負荷装置１から信号を受信してデータを取得する。 The air conditioning load device 1 that has received the request signal transmits a signal including data held by itself to the centralized management device 200a via the communication line 400. At the time of transmission, a signal in a format according to a preset communication frame is sent. The centralized management device 200a receives the signal from the air conditioning load device 1 and acquires data.
　前述したように、集中管理装置２００ｂは、集中管理装置２００ａと同じデータを有するようにしている。そこで、通信線４００を介して受信した信号に基づき、集中管理装置２００ｂは、送信先アドレス及び通信コマンドを判断する。そして、送信先アドレスが集中管理装置２００ａを表すものであり、要求信号に対する応答信号と判断すると、信号を受信して処理を行い、データを取得する。 As described above, the central management apparatus 200b has the same data as the central management apparatus 200a. Therefore, based on the signal received via the communication line 400, the centralized management apparatus 200b determines a transmission destination address and a communication command. When the transmission destination address represents the centralized management apparatus 200a and is determined as a response signal to the request signal, the signal is received and processed to acquire data.
　以上のように、実施の形態２の空気調和装置の通信システムによれば、通信線４００に流れる信号を、集中管理装置２００ｂが受信し、信号中の送信先アドレスと通信コマンドに基づいて、信号中の各種データを取得するようにしたので、例えば送信先アドレスが集中管理装置２００ａであれば同じデータを取得することができる。このため、通信線４００に集中管理装置２００を複数台接続しても、システム全体の通信トラフィックを抑制することができる。 As described above, according to the communication system of the air conditioning apparatus of the second embodiment, the central management device 200b receives the signal flowing through the communication line 400, and the signal is based on the transmission destination address and the communication command in the signal. Since various types of data are acquired, for example, if the transmission destination address is the centralized management apparatus 200a, the same data can be acquired. For this reason, even if a plurality of centralized management devices 200 are connected to the communication line 400, communication traffic of the entire system can be suppressed.
実施の形態３．
　図９は本発明の実施の形態３に係る装置間の通信を説明するための図である。図９に示すように、本実施の形態では、空気調和負荷装置１ａ、１ｂ、１ｃ、空気調和熱源装置５０、集中管理装置２００ａ、２００ｂ、リモートコントローラ装置１００ａ、１００ｂ及び保守装置２５０を通信線４００で接続している。 Embodiment 3 FIG.
FIG. 9 is a diagram for explaining communication between apparatuses according to Embodiment 3 of the present invention. As shown in FIG. 9, in this embodiment, the air conditioning load devices 1a, 1b, and 1c, the air conditioning heat source device 50, the centralized management devices 200a and 200b, the remote controller devices 100a and 100b, and the maintenance device 250 are connected to the communication line 400. Connected with.
　ここで、空気調和熱源装置５０は、空気調和熱源主装置５０ａと空気調和熱源補助装置５０ｂとで構成している。例えば、空気調和熱源主装置５０ａが、通信線４００を介して空気調和熱源補助装置５０ｂに要求信号を送信する。そして、空気調和熱源補助装置５０ｂからの応答信号に基づいて空気調和熱源補助装置５０ｂの圧力データ、配管等の温度データ、圧縮機５５の周波数データ、運転状態等の制御データを取得し、空気調和熱源装置５０全体として連携動作を行っている。 Here, the air-conditioning heat source device 50 includes an air-conditioning heat source main device 50a and an air-conditioning heat source auxiliary device 50b. For example, the air conditioning heat source main device 50a transmits a request signal to the air conditioning heat source auxiliary device 50b via the communication line 400. And based on the response signal from the air conditioning heat source auxiliary device 50b, the pressure data of the air conditioning heat source auxiliary device 50b, the temperature data of the piping, the frequency data of the compressor 55, the control data such as the operating state, etc. are acquired, and the air conditioning The heat source device 50 as a whole performs a cooperative operation.
　また、本実施の形態の保守装置２５０は、空気調和熱源補助装置５０ｂを保守するためのデータ（保守データ）を取得する。このため、空気調和熱源主装置５０ａから空気調和熱源補助装置５０ｂに送られる応答信号に基づいて、送信元アドレスと通信コマンドから、空気調和熱源主装置５０ａが取得する圧力データ、温度データ、周波数データ、運転状態等の制御データの中で保守に必要なデータを判断し、必要なデータを取得する。 Further, the maintenance device 250 of the present embodiment acquires data (maintenance data) for maintaining the air-conditioning heat source auxiliary device 50b. Therefore, based on the response signal sent from the air conditioning heat source main device 50a to the air conditioning heat source auxiliary device 50b, the pressure data, temperature data, and frequency data acquired by the air conditioning heat source main device 50a from the transmission source address and the communication command. The data necessary for maintenance is determined from the control data such as the operation state, and the necessary data is acquired.
　さらに、集中管理装置２００ａ、２００ｂも保守装置２５０と同様にして、空気調和熱源主装置５０ａが取得している圧力データ、温度データ、周波数データ、運転状態等の制御データから保守のために必要な情報送信元アドレスと通信コマンドで保守データと判断し通信フレームを受信し取得する。 Further, the central management devices 200a and 200b are also required for maintenance from the control data such as pressure data, temperature data, frequency data, and operating state acquired by the air-conditioning heat source main device 50a in the same manner as the maintenance device 250. Based on the information source address and communication command, it is determined as maintenance data, and a communication frame is received and acquired.
　以上のように、実施の形態３の空気調和装置の通信システムにおいては、保守装置２５０、集中管理装置２００ａ、２００ｂはデータの要求信号を送信することなく空気調和熱源補助装置の保守データが取得可能となるため、保守データを取得する装置を複数台接続してもシステム全体のトラフィックの抑制が可能となる。 As described above, in the air conditioner communication system according to the third embodiment, the maintenance device 250 and the centralized management devices 200a and 200b can acquire maintenance data of the air conditioning heat source auxiliary device without transmitting a data request signal. Therefore, even if a plurality of devices that acquire maintenance data are connected, the traffic of the entire system can be suppressed.
実施の形態４．
　図１０は本発明の実施の形態４に係る装置間の通信を説明するための図である。図１０に示す各装置及び接続形態については実施の形態１において説明した図７と同じである。ここで、本実施の形態では、リモートコントローラ装置１００ａ、１００ｂについても、タイマ等の計時装置を有しているものとする。本実施の形態は、空気調和負荷装置１に要求信号を送っていた集中管理装置２００が故障等したときのリモートコントローラ装置１００の処理等に関するものである。 Embodiment 4 FIG.
FIG. 10 is a diagram for explaining communication between apparatuses according to Embodiment 4 of the present invention. Each device and connection form shown in FIG. 10 are the same as those in FIG. 7 described in the first embodiment. Here, in the present embodiment, it is assumed that the remote controller devices 100a and 100b also have a timing device such as a timer. The present embodiment relates to processing of the remote controller device 100 when the centralized management device 200 that has sent a request signal to the air conditioning load device 1 breaks down.
　例えば、集中管理装置２００は、吸い込み温度の表示、各種データの保持等のために６０秒程度で定期的にデータの取得が必要な装置である。一方、リモートコントローラ装置１００ａ、１００ｂは、集中管理装置２００よりも頻繁に表示を更新する必要性がないため、定期的な吸い込み温度データの取得は１００秒程度でもよい。 For example, the centralized management device 200 is a device that needs to periodically acquire data in about 60 seconds for displaying the suction temperature and holding various data. On the other hand, since the remote controller devices 100a and 100b do not need to update the display more frequently than the centralized management device 200, the acquisition of the periodic suction temperature data may be about 100 seconds.
　そこで、リモートコントローラ装置１００ａ、１００ｂは、集中管理装置２００が要求信号を送信する周期よりも長い周期で要求信号を送信する。そして、吸い込み温度データを取得すると、計時装置をリセット処理する。ここで、リモートコントローラ装置１００ａの要求信号の通信周期を例えば１０１秒とし、リモートコントローラ装置１００ｂの要求信号の通信周期を例えば１０２秒として、異なる周期（時間）で設定する。このように要求信号の通信周期を異ならせることで、リモートコントローラ装置１００ａと１００ｂとが空気調和負荷装置に対して同時に要求信号を送信しないようにする。ここで、通信周期は例示であり、秒数等を限定するものではない（以下、同じ）。 Therefore, the remote controller devices 100a and 100b transmit the request signal in a cycle longer than the cycle in which the centralized management device 200 transmits the request signal. When the suction temperature data is acquired, the timing device is reset. Here, the communication cycle of the request signal of the remote controller device 100a is set to 101 seconds, for example, and the communication cycle of the request signal of the remote controller device 100b is set to 102 seconds, for example, and set with different cycles (time). Thus, by varying the communication cycle of the request signal, the remote controller devices 100a and 100b are prevented from simultaneously transmitting the request signal to the air conditioning load device. Here, the communication cycle is an example, and does not limit the number of seconds (hereinafter the same).
　実施の形態１において説明したように、集中管理装置２００は、空気調和負荷装置１に対し、６０秒毎に要求信号を送信し、空気調和負荷装置１が通信線４００を介して吸い込み温度データを含む信号を送信する。リモートコントローラ装置１００ａ、１００ｂは、信号を受信して吸い込み温度データを取得すると，計時装置をリセットする。このため、基本的には、リモートコントローラ装置１００ａ、１００ｂが空気調和負荷装置１に対して要求信号を送信する必要がない。 As described in the first embodiment, the centralized management device 200 transmits a request signal to the air conditioning load device 1 every 60 seconds, and the air conditioning load device 1 receives the suction temperature data via the communication line 400. Send the containing signal. When the remote controller devices 100a and 100b receive the signal and acquire the suction temperature data, they reset the timing device. For this reason, basically, it is not necessary for the remote controller devices 100a and 100b to transmit a request signal to the air conditioning load device 1.
　しかし、図１０に示すように、集中管理装置２００の故障、データ送信の際、外来ノイズの影響など何らかの原因で、リモートコントローラ装置１００ａ又は１００ｂが吸い込み温度データを取得できない場合がある。ここではリモートコントローラ装置１００ａが取得できないものとする。このとき、リモートコントローラ装置１００ａは空気調和負荷装置１に対して要求信号を送信する。 However, as shown in FIG. 10, the remote controller device 100a or 100b may not be able to acquire the suction temperature data due to some cause such as failure of the centralized management device 200 or the influence of external noise during data transmission. Here, it is assumed that the remote controller device 100a cannot be acquired. At this time, the remote controller device 100 a transmits a request signal to the air conditioning load device 1.
　リモートコントローラ装置１００ａからの要求信号を受信した空気調和負荷装置１は、吸い込み温度データを含む信号を通信線４００を介してリモートコントローラ装置１００ａに送信する。リモートコントローラ装置１００ａは空気調和負荷装置１から吸い込み温度データを含む信号を受信して吸い込み温度データを取得する。一方、リモートコントローラ装置１００ｂは、受信した信号の送信元アドレス及び通信コマンドに基づいて、吸い込み温度データを取得する。 The air conditioning load device 1 that has received the request signal from the remote controller device 100a transmits a signal including the suction temperature data to the remote controller device 100a via the communication line 400. The remote controller device 100a receives the signal including the suction temperature data from the air conditioning load device 1 and acquires the suction temperature data. On the other hand, the remote controller device 100b acquires the suction temperature data based on the transmission source address of the received signal and the communication command.
　そして、集中管理装置２００が、再び６０秒毎に要求信号を送信するようになると、リモートコントローラ装置１００は要求信号送信に係る周期が長いため、要求信号を送信しなくても吸い込み温度データを取得することができる。 Then, when the central management device 200 transmits a request signal every 60 seconds again, the remote controller device 100 acquires the suction temperature data without transmitting the request signal because the cycle related to the request signal transmission is long. can do.
　ここでは、リモートコントローラ装置１００ａが取得できないものとして、空気調和負荷装置１に対して要求信号を送信するようにしたが、リモートコントローラ装置１００ｂが要求信号を送信するようにしてもよい。 Here, the request signal is transmitted to the air-conditioning load device 1 on the assumption that the remote controller device 100a cannot acquire, but the remote controller device 100b may transmit the request signal.
　また、リモートコントローラ装置１００ａの要求信号の通信周期を１０１秒とし、リモートコントローラ装置１００ａの要求信号の通信周期を１０２秒としたが、これに限定するものではない。 Further, although the communication cycle of the request signal of the remote controller device 100a is 101 seconds and the communication cycle of the request signal of the remote controller device 100a is 102 seconds, it is not limited to this.
　ここでは、送信元アドレスと通信コマンドとに基づく判断処理を行ったが、実施の形態２等と同様に、送信先アドレスと通信コマンドとに基づいて行うようにしてもよい。 Here, the determination process based on the transmission source address and the communication command is performed, but the determination process may be performed based on the transmission destination address and the communication command as in the second embodiment.
　以上のように、実施の形態４の空気調和装置の通信システムによれば、リモートコントローラ装置１００に吸い込み温度データを取得するとリセットされる要求信号の通信周期を設定しておき、通信周期になると要求信号を送信するようにしたので、例えば、集中管理装置２００宛の信号に基づいて吸い込み温度データが取得できなくても、要求信号を送信して吸い込み温度データを取得することができる。要求信号を送信しなかった他の装置は通信線４００を流れる信号に基づいて吸い込み温度データを取得することができ、システム全体のトラフィックの抑制が可能となる。このとき、リモートコントローラ装置１００ａとリモートコントローラ装置１００ｂとで異なる通信周期を設定しておけば、同時に要求信号を送信する可能性が極めて低くなり、信号の衝突等を防ぐことができる。 As described above, according to the communication system of the air conditioning apparatus of the fourth embodiment, the communication cycle of the request signal that is reset when the suction temperature data is acquired is set in the remote controller device 100, and is requested when the communication cycle is reached. Since the signal is transmitted, for example, the suction temperature data can be acquired by transmitting the request signal even if the suction temperature data cannot be acquired based on the signal addressed to the central management apparatus 200. Other devices that have not transmitted the request signal can acquire the suction temperature data based on the signal flowing through the communication line 400, and the traffic of the entire system can be suppressed. At this time, if different communication cycles are set between the remote controller device 100a and the remote controller device 100b, the possibility of transmitting request signals at the same time becomes extremely low, and signal collisions and the like can be prevented.
実施の形態５．
　前述した実施の形態４では、リモートコントローラ装置１００ａの要求信号の通信周期を１０１秒とし、リモートコントローラ装置１００ａの要求信号の通信周期を１０２秒とした。本実施の形態では、例えばアドレスは各装置において異なることから、アドレスに基づいた通信周期を設定するようにしたものである。 Embodiment 5 FIG.
In the fourth embodiment described above, the communication cycle of the request signal of the remote controller device 100a is 101 seconds, and the communication cycle of the request signal of the remote controller device 100a is 102 seconds. In the present embodiment, for example, since the address is different in each device, a communication cycle based on the address is set.
　本実施の形態においては、１００秒＋アドレスの下１桁×１００ｍｓ後に要求信号を送信するようにリモートコントローラ装置１００の通信周期を設定する。リモートコントローラ装置１００ａにアドレス１０１が設定されており、リモートコントローラ装置１００ｂにアドレス１０２が設定されている。このため、リモートコントローラ装置１００ａの通信周期は１００．１秒となり、リモートコントローラ装置１００ｂの通信周期は１００．２秒となる。 In the present embodiment, the communication cycle of the remote controller device 100 is set so that the request signal is transmitted after 100 seconds + the last digit of the address × 100 ms. The address 101 is set in the remote controller device 100a, and the address 102 is set in the remote controller device 100b. For this reason, the communication cycle of the remote controller device 100a is 100.1 seconds, and the communication cycle of the remote controller device 100b is 100.2 seconds.
　そして、何らかの原因により、リモートコントローラ装置１００ａ又は１００ｂが、前述のように、アドレスに基づいて設定した通信周期の間に吸い込み温度データを取得できない場合には、実施の形態４と同様に空気調和負荷装置１に要求信号を送信する。 If, for some reason, the remote controller device 100a or 100b cannot acquire the suction temperature data during the communication cycle set based on the address as described above, the air conditioning load is the same as in the fourth embodiment. A request signal is transmitted to the device 1.
　ここでは、送信元アドレスと通信コマンドとに基づく判断処理を行ったが、実施の形態２等と同様に、送信先アドレスと通信コマンドとに基づいて行うようにしてもよい。 Here, the determination process based on the transmission source address and the communication command is performed, but the determination process may be performed based on the transmission destination address and the communication command as in the second embodiment.
　以上のように、実施の形態５の空気調和装置の通信システムによれば、各装置に固有に定められたアドレスに基づいて通信周期を定めるようにしたので、通信システム内において、各装置の通信周期が同じにならずにすむ。 As described above, according to the communication system of the air conditioning apparatus of the fifth embodiment, the communication cycle is determined based on the address uniquely determined for each apparatus. The period does not have to be the same.
実施の形態６．
　図１１は本発明の実施の形態６に係る装置間の通信を説明するための図である。図１１では、空気調和負荷装置１は、集中管理装置２００ａ、２００ｂ、リモートコントローラ装置１００ａ、１００ｂ及び保守装置２５０と通信線４００で接続されている。本実施の形態では、保守装置２５０、リモートコントローラ装置１００ａ、１００ｂについても、タイマ等の計時装置を有しているものとする。 Embodiment 6 FIG.
FIG. 11 is a diagram for explaining communication between apparatuses according to Embodiment 6 of the present invention. In FIG. 11, the air conditioning load device 1 is connected to the centralized management devices 200 a and 200 b, the remote controller devices 100 a and 100 b, and the maintenance device 250 through the communication line 400. In the present embodiment, it is assumed that the maintenance device 250 and the remote controller devices 100a and 100b also have a timing device such as a timer.
　本実施の形態は、空気調和負荷装置１に要求信号を送っていた集中管理装置２００ａが故障等したときの他の装置の処理等に関するものである。例えば、集中管理装置２００は、吸い込み温度の表示、各種データの保持等のために６０秒程度で定期的にデータの取得が必要な装置である。一方、リモートコントローラ装置１００ａ、１００ｂは、集中管理装置２００よりも頻繁に表示を更新する必要性がないため、定期的な吸い込み温度データの取得は１００秒程度でもよい。また、保守装置２５０も、集中管理装置２００と同様に、吸い込み温度の表示、データ保持のために、同じく６０秒程度で定期的にデータの取得が必要な装置である。本実施の形態では、保守装置２５０は保守が必要な場合に通信線４００に接続する装置である。 This embodiment relates to processing of other devices when the central management device 200a that has sent a request signal to the air conditioning load device 1 fails. For example, the central management device 200 is a device that needs to acquire data regularly in about 60 seconds for displaying the suction temperature, holding various data, and the like. On the other hand, since the remote controller devices 100a and 100b do not need to update the display more frequently than the centralized management device 200, the acquisition of the periodic suction temperature data may be about 100 seconds. Similarly to the central management device 200, the maintenance device 250 is also a device that needs to periodically acquire data in about 60 seconds in order to display the suction temperature and hold the data. In the present embodiment, maintenance device 250 is a device connected to communication line 400 when maintenance is required.
　本実施の形態では、集中管理装置２００ａの要求信号の通信周期を例えば６０秒とする。また、集中管理装置２００ｂの要求信号の通信周期を例えば６１秒とし、保守装置２５０の要求信号の通信周期を例えば６５秒とする。さらに、リモートコントローラ装置１００ａ、１００ｂの要求信号の通信周期を１２１秒とする。 In this embodiment, the communication cycle of the request signal of the central management apparatus 200a is set to 60 seconds, for example. Further, the communication cycle of the request signal of the central management device 200b is set to 61 seconds, for example, and the communication cycle of the request signal of the maintenance device 250 is set to 65 seconds, for example. Furthermore, the communication cycle of the request signals of the remote controller devices 100a and 100b is 121 seconds.
　集中管理装置２００は、空気調和負荷装置１に対し、６０秒毎に要求信号を送信し、空気調和負荷装置１が通信線４００を介して吸い込み温度データを含む信号を送信する。保守装置２５０、集中管理装置２００ｂ、リモートコントローラ装置１００ａ、１００ｂは、信号を受信して吸い込み温度データを取得すると，計時装置をリセットする。このため、基本的には、保守装置２５０、集中管理装置２００ｂ、リモートコントローラ装置１００ａ、１００ｂが空気調和負荷装置１に対して要求信号を送信する必要がない。 The centralized management device 200 transmits a request signal to the air conditioning load device 1 every 60 seconds, and the air conditioning load device 1 transmits a signal including suction temperature data via the communication line 400. When the maintenance device 250, the central management device 200b, and the remote controller devices 100a and 100b receive the signal and acquire the suction temperature data, they reset the timing device. For this reason, basically, the maintenance device 250, the centralized management device 200b, and the remote controller devices 100a and 100b do not need to transmit a request signal to the air conditioning load device 1.
　しかし、集中管理装置２００ａの故障により、集中管理装置２００ｂ、リモートコントローラ装置１００ａ、１００ｂ及び保守装置２５０が吸い込み温度データを取得できない場合がある。このとき、集中管理装置２００ａに変わって、いずれかの装置が、空気調和負荷装置１に対して要求信号を送信する。 However, due to the failure of the central management device 200a, the central management device 200b, the remote controller devices 100a and 100b, and the maintenance device 250 may not be able to acquire the suction temperature data. At this time, instead of the centralized management device 200a, one of the devices transmits a request signal to the air conditioning load device 1.
　そして、本実施の形態では、空気調和負荷装置１に対して要求信号を送信する装置を、システムにおいて装置が有する特徴（機能、種類）等で決める。例えば、データを保持のために短い周期でデータを取得する必要のある装置の優先順位を高くして通信周期を設定する。また、短い周期でデータを取得する必要のある装置が複数ある場合には、常に通信線４００と接続する装置の優先順位を高く設定して通信周期を設定する。そこで、（１）常に通信線４００に接続し、データの取得周期が短い装置、（２）必要な場合に通信線４００に接続し、データの取得周期が短い装置、（３）常に通信線４００に接続し、データの取得周期が長い装置の順に、優先順位を定める。 And in this Embodiment, the apparatus which transmits a request signal with respect to the air conditioning load apparatus 1 is determined by the characteristic (function, kind) etc. which an apparatus has in a system. For example, the communication cycle is set by increasing the priority of a device that needs to acquire data in a short cycle to hold the data. In addition, when there are a plurality of devices that need to acquire data in a short cycle, the communication cycle is set by always setting the priority of the device connected to the communication line 400 high. Therefore, (1) a device that is always connected to the communication line 400 and has a short data acquisition cycle, (2) a device that is connected to the communication line 400 when necessary and has a short data acquisition cycle, and (3) a communication line 400 that is always connected. The priority order is determined in the order of devices having a long data acquisition cycle.
　本実施の形態では、常に通信線４００に接続し、データの取得周期が短い集中管理装置２００ｂに対して６１秒の通信周期を設定しているため、集中管理装置２００ｂは空気調和負荷装置１に対して要求信号を送信する。これにより、例えば集中管理装置２００ａが故障しても、他の装置による吸い込み温度データの取得に係る処理を継続することができる。また、集中管理装置２００ｂが故障等すると、次に優先順位が高い保守装置２５０が６５秒毎に要求信号を送信する。 In the present embodiment, since the communication cycle of 61 seconds is set for the central management device 200b that is always connected to the communication line 400 and has a short data acquisition cycle, the central management device 200b is connected to the air conditioning load device 1. In response, a request signal is transmitted. Thereby, for example, even if the centralized management device 200a breaks down, it is possible to continue processing related to acquisition of suction temperature data by another device. Further, when the central management device 200b fails, the maintenance device 250 having the next highest priority transmits a request signal every 65 seconds.
　一方、集中管理装置２００ａが、再び６０秒毎に要求信号を送信するようになると、他の装置は要求信号送信に係る周期が長いため、要求信号を送信しなくても吸い込み温度データを取得することができる。 On the other hand, when the central management apparatus 200a transmits a request signal every 60 seconds again, the other apparatuses acquire the suction temperature data without transmitting the request signal because the period related to the request signal transmission is long. be able to.
　ここで、リモートコントローラ装置１００ａ、１００ｂの優先順位は特に決めず、通信周期も１２１秒としたが設定するようにしてもよい。このとき、実施の形態５で説明したように、アドレスに依存した優先順位により通信周期を設定してもよい。 Here, the priority order of the remote controller devices 100a and 100b is not particularly determined, and the communication cycle may be set to 121 seconds. At this time, as described in the fifth embodiment, the communication cycle may be set according to the priority order depending on the address.
　以上のように、実施の形態６の空気調和装置の通信システムによれば、装置の特徴により通信周期を定めるようにしたので、短い周期でデータを必要とする装置を優先して設定することができる。 As described above, according to the communication system of the air conditioning apparatus of the sixth embodiment, since the communication cycle is determined according to the characteristics of the device, it is possible to preferentially set a device that requires data in a short cycle. it can.
　実施の形態７．
