〔産業上の利用分野〕
本発明は、空調制御における警報出力方式に係り、特に
、温度制御方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an alarm output method in air conditioning control, and particularly to a temperature control method.
従来は設備の警報があった場合にその設備をＣＲＴ上で
フリッカ等させて警報を外部へ伝達する方法（特願昭６
２−２２２４９３号明細書）はあったが、測定値の異常
から不良設備を予測し、しかも、音声で警報出力する様
な方式はなかった。Conventionally, when there is an alarm from equipment, the equipment is flickered on a CRT to transmit the alarm to the outside (Japanese Patent Application No. 6)
2-222493), but there was no system that could predict defective equipment from abnormalities in measured values and issue an audio warning.
上記従来技術は、空調制御を行っているにも関らず、室
温の上限、あるいは、下限異常が発生した場合、温度異
常が発生した事は、ＣＲＴ、あるいは、音声で伝える方
式があったが、システム側の制御は悪いのか、あるいは
、設備側が悪いのかを判定して、その結果を伝える方式
がなかった。In the above-mentioned conventional technology, if an abnormality occurs in the upper or lower limit of the room temperature even though air conditioning is being controlled, the occurrence of the temperature abnormality is communicated by CRT or voice. There was no way to determine whether the control on the system side or the equipment was at fault, and to communicate the results.
このため、管理人は、担当者を呼んで制御側と設備側の
両方を調査する必要があった。For this reason, the manager had to call a person in charge to investigate both the control side and the equipment side.
本発明の目的は、温度異常が発生した後の温度上昇（下
降）の傾向と、二方弁の開度より制御側が異常なのか、
あるいは、設備側が異常なのかを判定しその結果を音声
により監視人に伝え、管理側の負担を減らすことにある
。The purpose of the present invention is to determine whether there is an abnormality on the control side based on the tendency of temperature rise (fall) after a temperature abnormality occurs and the opening degree of the two-way valve.
Alternatively, it is possible to reduce the burden on the management side by determining whether there is an abnormality on the equipment side and conveying the result to the supervisor by voice.
上記目的を達成するために、本発明は室温と二方弁の開
度とから、発生した温度異常がシステム側の制御による
ものなのか、あるいは、設備側の不良によるものなのか
を判定する発生警報判定部を設けた。In order to achieve the above object, the present invention determines whether the temperature abnormality that has occurred is due to control on the system side or a malfunction on the equipment side, based on the room temperature and the opening degree of the two-way valve. An alarm judgment section was installed.
さらに、この判定部により決定された結論を音声で外部
に伝えることができる音声警報装置を設けた。Furthermore, an audio warning device was provided that can communicate the conclusion determined by the determination section to the outside by voice.
本制御本式では、空調機の温度制御を行う二方弁開度決
定部と、取込んだ室温と二方弁開度から温度異常を判定
する発生警報判定部を独立して設けた。また、判定部に
よる判定結果に基づき、各種警報を発する音声警報装置
も独立して設けた。In this control system, a two-way valve opening determining section that controls the temperature of the air conditioner and an occurrence alarm determining section that determines temperature abnormality from the taken room temperature and the two-way valve opening are independently provided. In addition, an audio warning device was also provided independently to issue various warnings based on the determination results by the determination unit.
これにより、開度決定部分と警報判定部が相互に影響し
合うことなく、監視することができる。また、警報装置
を独立にすることで、警報の種類が−
変更になった場合でも、これを交換するだけで対応でき
、他の装置へ影響を与えることはない。Thereby, the opening determining section and the alarm determining section can monitor each other without influencing each other. Furthermore, by making the alarm device independent, even if the type of alarm changes, it can be handled simply by replacing it, and other devices will not be affected.
以下、本発明の一実施例を第１図ないし第３図により説

。FIG. 1 is a system configuration diagram of the present invention. A two-way valve 11 that adjusts the amount of cold/hot water flowing into the device consisting of a coil, fan, etc.
, a temperature sensor 12 for determining the season of summer or winter from the temperature of cold/hot water, and a temperature sensor 13 for detecting the room temperature of the controlled object. Furthermore, a two-way valve opening determination unit 21 determines the opening of the two-way valve based on the room temperature, the two-way valve opening, and the seasonal mode, and a determination unit determines whether an alarm occurs based on the detected room temperature and the two-way valve opening. 22, and an audio warning device 3 that transmits a warning to the outside by voice.
第２図は、夏，冬の各季節において、上，下限温度異常
と設備異常の音声警報が発せられるタイミングについて
示したものである。FIG. 2 shows the timing at which audio warnings for upper and lower limit temperature abnormalities and equipment abnormalities are issued in each season of summer and winter.
４− 以下、夏季を例にとり説明する。4- This will be explained below using summer as an example.
いま、初期条件として設定値２４℃，上限値２７゜Ｃ，
下限値２１℃を設定しているものとする。Now, the initial conditions are a set value of 24°C, an upper limit of 27°C,
It is assumed that the lower limit value is set to 21°C.
温度制御を行っているにもかかわらず室温が上昇し、上
限値を越えると（■の状態）このタイミングで″上限異
常発生″の音声警報が発せられる。If the room temperature rises despite the temperature control and exceeds the upper limit (state ■), an audio warning "upper limit abnormality has occurred" is issued at this timing.
さらに、この警報が発せられてから一定時間後の室温が
■の室温より更に高くなっており、かつ、二方弁が全開
の場合には設備側の異常と判断し″冷温水発生機を調査
して下さい。″という音声警報が発せられる（■の状態
）。これは、温度制御を行っているにもかかわらず、室
温が上昇するのは冷温水発生機の能力が低下していると
判断することができるからである。Furthermore, if the room temperature after a certain period of time after this alarm is issued is even higher than the room temperature in (■), and the two-way valve is fully open, it will be determined that there is an abnormality on the equipment side, and the hot and cold water generator will be investigated. Please do so.'' will be issued (state of ■). This is because if the room temperature rises despite temperature control, it can be determined that the capacity of the cold/hot water generator is decreasing.
また、逆に温度制御を行っているにもかかわらず室温が
下降し、下限値を越えた時には（■の状態）″下限異常
発生″の音声警報を発する。さらに、この警報が発せら
れてから一定時間後の室温が■の室温よりさらに低くな
り、かつ、二方弁が全閉している場合には設備側の異常
と判断し″二方弁がしまりきりません。弁を調査して下
さい。On the other hand, when the room temperature drops despite temperature control and exceeds the lower limit (state ■), an audio warning of "lower limit abnormality has occurred" is issued. Furthermore, if the room temperature after a certain period of time after this alarm is issued becomes even lower than the room temperature in (■) and the two-way valve is fully closed, it will be determined that there is an abnormality on the equipment side, and the two-way valve will close. No. Please investigate the valve.
という音声警報が発せられる（■の状態）。これは温度
制御を行っているにもかかわらず室温が下がるのは二方
弁がしまりきらずに冷水がもれていると判断することが
できるからである。An audio warning will be issued (state of ■). This is because if the room temperature drops despite temperature control, it can be determined that the two-way valve is not fully closed and cold water is leaking.
このように、音声警報を二段階で発し、設備側の不良を
監視人に知らせることが可能となる。In this way, it is possible to issue an audio warning in two stages to notify the supervisor of a malfunction on the equipment side.
尚、冬季の場合は夏季の場合の逆の音声警報となる。即
ち、上限，下限の異常発生時（■，■の状態）は同じ音
声警報であるが、■，■の状態では、夫々夏季の場合の
■，■の音声警報とする。In addition, in the case of winter, the voice warning is the opposite of that in summer. That is, when an abnormality occurs at the upper and lower limits (states of ■ and ■), the same audio warning is issued, but in states of ■ and ■, the audio warnings of ■ and ■ for summer are used, respectively.

。Check the room temperature using the indoor temperature sensor (step 10)
, and are compared with the set upper and lower limit values (step 20). If there is no abnormality, the process returns to step 10, and if there is an abnormality, the error temperature is stored (step 30) and an audio warning of upper/lower limit abnormality is generated (step 40). After the alarm occurs, it is monitored whether the temperature abnormality continues for a certain period of time (steps 90 to 110), and if it has not recovered, the process returns to step (step 10), and if the temperature abnormality continues for a certain period of time, it is monitored. The process goes to step (step 60), and the season is determined based on the temperature of the cold/hot water. Check the relationship between the two-way valve opening and room temperature for both summer and winter (step 70), and issue an audio alarm for equipment abnormality (step 80).
.
そして冬時の処理は、その次の判定が夏時の反対になる
（ステップ１２０）。Then, in the winter processing, the next determination is the opposite of the summer processing (step 120).

ことができる。According to the present invention, whereas conventionally, temperature abnormalities were only caused by upper and lower limit errors, it is possible to determine whether temperature abnormalities caused by room temperature and two-way valve opening are caused by the control side or by the equipment side. It is possible to determine whether the information is correct and communicate this to the outside via voice. Furthermore, it is possible to limit abnormal equipment, such as which equipment is malfunctioning or which two-way valve is malfunctioning.
こうして、監視人は不良箇所のシステム／設備の切り割
けが可能になり監視人の負担を減らすことができる。In this way, the supervisor can isolate the defective system/equipment, reducing the burden on the supervisor.
