본 발명은 열차 실내의 냉 ·난방 및 환기 등 공기조화를 제어하는 기술에 관한 것으로서, 보다 상세하게는, 열차 실내 ·외의 온도 감지를 통해 공기조화의 모드를 능동적으로 제어하는 열차의 공조 제어장치 및 그 제어방법에 관한 것이다.The present invention relates to a technology for controlling air conditioning such as cooling, heating, and ventilation of a train interior, and more particularly, an air conditioning control apparatus for a train that actively controls a mode of air conditioning by sensing a temperature inside and outside a train; The control method is related.

각종 철도 차량 즉 열차에는 실내의 냉/난방과 환기 등을 수행하기 위한 공기조화장치가 설치되어 있으며, 공기조화장치에 대한 제어는 통상적으로 열차 운전실에 마련되어 있는 로터리 스위치를 조작함으로써 이루어지고 있다.Various railway vehicles, that is, trains are provided with an air conditioner for performing indoor cooling / heating and ventilation, and the control of the air conditioner is usually performed by operating a rotary switch provided in a cab of a train.

즉, 종래의 로터리 스위치는, 첨부도면 도 1에 도시된 바와 같이, '반냉, 전냉, 오프(OFF), 1/3 난방, 2/3 난방, 3/3 난방, 환기' 등의 모드로 구분되어 있으며, 운전실에서 로터리 스위치를 조작하면 해당 모드로 공기조화가 이루어지게 된다.That is, conventional rotary switches are divided into modes such as 'semi-cooled, pre-cooled, off, 1/3 heating, 2/3 heating, 3/3 heating, and ventilation' as shown in FIG. If the rotary switch is operated in the cab, air conditioning is performed in the corresponding mode.

특히, 종래의 공조 제어 시스템의 개략적인 구성은, 도 2에 도시된 바와 같이, 로터리 스위치(1)와 이 로터리 스위치(1)로부터 신호를 입력받아 해당 모드별로 공조장치(5)의 제어가 이루어지도록 작동되는 배전반(2) 및 접촉기(3), 그리고 열차의 실내 온도를 감지하는 실내온도센서(4)로 이루어져 있다. 이러한 종래의 공조 제어 시스템에서는, 로터리 스위치(1)의 조작에 의해 해당 모드의 공기조화가 이루어지다가 열차 실내 온도가 세팅된 온도에 도달하면 이를 실내온도센서(4)가 감지하여 냉방 또는 난방등의 작동이 정지되도록 하게 된다.In particular, the schematic configuration of the conventional air conditioning control system, as shown in Figure 2, receives a signal from the rotary switch 1 and the rotary switch 1, the air conditioner (5) is controlled for each mode It consists of a switchboard (2) and a contactor (3) which is operated to be built, and an indoor temperature sensor (4) which senses the room temperature of the train. In such a conventional air conditioning control system, when the air conditioning of the corresponding mode is achieved by the operation of the rotary switch 1, when the room temperature of the train reaches the set temperature, the room temperature sensor 4 detects the air temperature or the like, such as cooling or heating. This will cause the operation to stop.

그런데, 전술한 바와 같은 종래의 공조 제어 시스템은, 열차 실내 ·외의 온도 상황과는 무관하게 운전자가 임의로 냉/난방 등의 강도를 로터리 스위치(1)만으로 설정하여 운전함에 따라 적절한 실내 냉/난방이 이루어지지 못하게 되는 문제가 있다. 더욱이, 열차의 실외온도는 전혀 고려하지 않은 채 운전자의 자의적인 판단만으로 공조장치가 가동되기 때문에 냉/난방 운전의 적절성은 현저히 떨어지게 된다.However, according to the conventional air conditioning control system as described above, regardless of the temperature inside or outside the train, the appropriate indoor cooling / heating can be achieved as the driver arbitrarily sets the intensity of cooling / heating to the rotary switch 1 alone. There is a problem that can not be achieved. Moreover, since the air conditioning system operates only at the discretion of the driver without considering the outdoor temperature of the train at all, the suitability of cooling / heating operation is significantly reduced.

도 5 및 도 6은 각각 본 발명에 따른 공조 제어방법을 나타낸 흐름도로서, 전술한 공조장치 및 공조 제어장치를 포함한 시스템의 운전하에서 이루어진다.5 and 6 are flow charts showing the air conditioning control method according to the present invention, respectively, under the operation of the system including the air conditioning apparatus and the air conditioning control apparatus described above.

먼저, 마이콤 콘트롤러(30)의 프로그램상에는 공조장치의 냉/난방 개시를 위한 냉/난방 개시 온도값이 설정되는데, 여기서 '냉/난방 개시 온도값'이란 차량 실내 온도가 어느 온도에 이르렀을 때 냉방이나 난방이 가동되는지를 운영자가 설정하는 임계값으로서, 운영자의 희망에 따라 임의로 설정하면 된다. 한편, 열차 실내의 이격된 두 부위(예컨대 열차 실내의 전후 양단부)에 설치된 제1실내온도센서(21)와 제2실내온도센서(22)가 각각 감지한 제1실내온도 및 제2실내온도에 대하여 마이콤 콘트롤러(30)가 그 평균값을 산출하고, 이와 아울러 실외온도센서(23)가 외기온도를 감지하는 과정이 일차적으로 수행된다(S1).First, in the program of the microcomputer controller 30, a cooling / heating start temperature value for cooling / heating start of the air conditioner is set, where 'cooling / heating start temperature value' refers to cooling when the vehicle room temperature reaches a certain temperature. In addition, it is a threshold value which an operator sets whether heating is operated, and you may set arbitrarily according to an operator's request. On the other hand, the first indoor temperature and the second indoor temperature detected by the first indoor temperature sensor 21 and the second indoor temperature sensor 22 installed at two spaced apart parts of the train interior (for example, both front and rear ends of the train interior). The microcomputer controller 30 calculates the average value, and at the same time, the process of sensing the outdoor temperature by the outdoor temperature sensor 23 is primarily performed (S1).

이어서, 마이콘 콘트롤러(30)는 상기 외기온도가 냉방조건인지 난방조건인지 를 판단하는데(S2), 예를 들어 외기온도가 20℃ 이상일 경우에는 냉방이 필요한 상태인 냉방조건으로 판단하고, 외기온도가 20℃ 미만일 경우에는 난방이 필요한 상태인 난방조건으로 판단한다.Subsequently, the micon controller 30 determines whether the outside air temperature is a cooling condition or a heating condition (S2). For example, when the outside air temperature is 20 ° C. or more, it is determined as a cooling condition that requires cooling, and the outside air temperature is If it is less than 20 ℃, it is determined as heating condition that requires heating.

그리고, 외기온도가 냉방조건 즉 20℃ 이상일 경우, 실내온도 평균값과 냉방 개시 온도값을 비교한 값을 산출하는데(S3), 이는 실내온도 평균값에서 냉방 개시 온도값을 뺀 결과로서 이를 비교값①이라 한다.In addition, when the outside temperature is the cooling condition, that is, 20 ° C. or more, a value obtained by comparing the average temperature of the room temperature and the cooling start temperature is calculated (S3). do.

상기 비교값①이 강냉방 운전조건인지 약냉방 운전조건인지를 판단하여(S4), 강냉방 운전조건일 경우에는 강냉방을 행하는데(S5), 예를 들어 강냉방 운전조건은 상기 비교값①이 3℃ 이상일 경우로 하고, 약냉방 운전조건은 상기 비교값①이 0∼3℃일 경우로 설정한다.It is determined whether the comparison value ① is a strong cooling operation condition or a weak cooling operation condition (S4), and in the case of a strong cooling operation condition, strong cooling is performed (S5). For example, the strong cooling operation condition is the comparison value ①. It is set to the case of 3 degreeC or more, and weak cooling operation conditions are set to the case where the said comparative value (1) is 0-3 degreeC.

또, 비교값①이 약냉방 운전조건인지 환기 운전조건인지를 판단하여(S6), 약냉방 운전조건경우에는 약냉방을 행하며(S7), 환기 운전조건일 경우에는 공조장치(10)의 압축기 작동을 차단하여 송풍팬에 의한 환기운전만이 이루어지도록 한다(S8). 여기서, 환기 운전조건은, 예를 들어 상기 비교값①이 0℃ 미만일 경우로 설정한다.In addition, it is determined whether the comparative value ① is a weak cooling operation condition or a ventilation operation condition (S6), and in the case of the weak cooling operation condition, the weak cooling is performed (S7), and in the case of the ventilation operation condition, the compressor of the air conditioner 10 is operated. By blocking the only ventilation operation by the blowing fan is made (S8). Here, the ventilation operation condition is set to the case where the said comparative value (1) is less than 0 degreeC, for example.

한편, 상기 S2 과정에서 외기온도가 난방조건 즉 20℃ 미만으로 판단된 경우에는, 실내온도 평균값과 난방 개시 온도값을 비교한 값을 산출하는데(S9), 이는 난방 개시 온도값에서 실내온도 평균값을 뺀 결과로서 이를 비교값②라 한다.On the other hand, if it is determined that the outside temperature is less than 20 ℃ heating conditions in the process S2, and calculates the value of comparing the average value of the room temperature and the heating start temperature value (S9), which is the average temperature of the room temperature from the heating start temperature value The result of subtraction is referred to as the comparison value ②.

이어서, 상기 비교값②가 3/3난방 운전조건인지 여부를 판단하는데(S10), 여기서 3/3난방 운전조건은 예를 들어 비교값②가 4℃를 초과하는 경우로 설정한다. 이에 따라, 비교값②가 4℃를 초과한 경우에는 3/3난방 운전을 행함으로써 난방기 용량이 최대로 발휘되는 수준의 실내 난방이 이루어지게 된다(S11).Subsequently, it is determined whether the comparison value ② is a 3/3 heating operation condition (S10), where the 3/3 heating operation condition is set, for example, when the comparison value ② exceeds 4 ° C. Accordingly, when the comparative value ② exceeds 4 ° C., the heating is performed at a level where the heater capacity is maximized by performing 3/3 heating operation (S11).

그리고, 상기 비교값②가 3/3난방 운전조건이 아닌 경우에는, 2/3난방 운전조건인지를 판단하는데(S2), 2/3난방 운전조건은 예컨대 상기 비교값②가 2∼4℃일 경우로 설정한다. 따라서, 비교값②가 2∼4℃ 범위이면 2/3난방 운전을 행함으로써 난방기 용량이 중간 수준으로 발휘되는 정도의 실내 난방이 이루어지게 된다(S13).When the comparison value ② is not a 3/3 heating operation condition, it is determined whether it is a 2/3 heating operation condition (S2), and the 2/3 heating operation condition is, for example, the comparison value ② is 2 to 4 ° C. Set to case. Therefore, when the comparative value ② is in the range of 2 to 4 ° C., 2/3 heating operation is performed to achieve room heating of the level at which the heater capacity is exhibited at an intermediate level (S13).

또, 상기 비교값②가 2/3난방 운전조건도 아닌 경우에는, 1/3난방 운전조건인지를 판단하는데(S14), 1/3난방 운전조건은 예를 들어 상기 비교값②가 0∼2℃ 미만일 경우로 설정한다. 이에 따라, 비교값②가 0∼2℃ 미만일 경우에는 1/3난방 운전을 행함으로써 난방기 용량이 가장 낮은 수준으로 발휘되는 정도로 실내 난방이 이루어지게 된다(S15).If the comparison value ② is not a 2/3 heating operation condition, it is determined whether it is a 1/3 heating operation condition (S14), and for the 1/3 heating operation condition, the comparison value ② is 0 to 2, for example. It is set to less than ° C. Accordingly, when the comparative value ② is less than 0 to 2 ° C., the heating is performed to the extent that the heater capacity is exhibited at the lowest level by performing 1/3 heating operation (S15).
