As described above, it is effective to display the outside air temperature only on the master unit. However, if the air-conditioning equipment or the like is controlled using the information, energy saving control can be performed. Also, if the indoor temperature is significantly different from the outside air temperature, and if it is too cold or too hot, the visitor may get sick due to a sudden temperature change. It is possible to implement air conditioning control that is gentle and friendly.
On the other hand, in hospitals, the temperature of a hospital room and the hallway in front of it may be different. For this situation, by providing temperature information to the intercom system (nurse call system), it is possible to control the temperature difference between the room and the hallway to create a patient-friendly environment. In addition, power can be saved.

  Therefore, in view of such a point, the present invention aims to enable control of indoor air-conditioning equipment using outside air temperature information measured by an entrance handset in a house, and a nurse call handset in a hospital. The purpose is to be able to control the temperature in the hallway in front of the sickroom by measuring the temperature in the sickroom on the side.

In order to solve the above-mentioned problem, the invention according to claim 1 is an interphone system including an entrance cordless handset for calling a resident and a living room base phone for a resident to respond.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, embodiments of the invention will be described in detail with reference to the drawings.
<First Embodiment Corresponding to Claim 1>
FIG. 1 is a block diagram showing a first embodiment of an intercom system according to the present invention, and shows an intercom system installed in a detached house. As shown in FIG. 1, there is an entrance handset 1 for calling a resident installed at the entrance or the like, and an in-home base unit 2 for answering the call set up in the living room. A call button 4 for performing a call operation, a thermometer 5 for measuring an outside air temperature, a call unit 6 having a microphone and a speaker (not shown), and an interface (slave unit IF) 7 for communicating with the room base unit 2 are provided. The thermometer 5 includes an A / D converter, and includes a transmission circuit that digitally converts the measured temperature and transmits the converted temperature to the room master unit 2.

  In addition, the living room master unit 2 has a microphone 9 and a speaker (not shown) to respond to the call, a display unit 10 that displays temperature information transmitted from the entrance unit 1, and a control signal to an air conditioner such as an air conditioner. An output terminal 11 for transmission, a setting unit 12 for a resident to input operation parameters of an output signal such as an air conditioner temperature setting, a control unit (parent device control unit) 13 having a CPU and controlling the parent unit 2; An interface (base unit IF) 14 for communicating with the entrance unit 1 is provided. In addition, when the camera which images a visitor is provided in the entrance cordless handset 1, the display part 10 serves as the monitor.

The intercom system configured in this way operates and operates as follows. However, since the operation from the front cordless handset 1 that is the basic operation of the interphone and the response by the living room base unit 2 are the same as the conventional one, the description is omitted, and the flow of measurement information of the thermometer 5 and the information thereof are omitted. The control will be described.
First, the temperature of the air conditioner to be controlled is set. The setting unit 12 is operated by the resident, and for example, in the case of the cooling setting, the setting of [cooling / outside temperature of set temperature−5 ° C./set lower limit temperature of 28 ° C.] is made. This indicates that the indoor cooling is set to 28 ° C., but priority is given to setting the temperature difference from the outside air temperature to 5 degrees or less.

  In this way, the base unit control unit 13 of the room base unit 2 in which the temperature is set performs a control operation according to the flow shown in FIG. When the temperature setting (S1) such as 28 ° C. is made by the setting unit 12, the control is started in response to the input of the outside air temperature information (S2). First, it is determined whether or not the outside air temperature exceeds 33 ° C. (28 ° C. plus 5 ° C.) (S3). If it exceeds, the temperature setting of the air conditioner is set to the outside air temperature -5 ° C (S4). If it is 33 degrees C or less, it will be judged whether it exceeds 28 degrees C next (S5). If it exceeds 28 ° C, the air conditioner temperature is set to 28 ° C (S6). If it is 28 degrees C or less, a stop signal will be output and an air conditioner will be stopped (S7). The above control signals are received periodically after receiving the outside air temperature information.

By such control, when the outside air temperature is 34 ° C., for example, an instruction for setting the temperature 29 ° C. is issued to the air conditioner, and the temperature is set to 1 ° C. higher than the set temperature 28 ° C. Also, when the outside air temperature falls to 33 ° C., an instruction for setting the temperature at 28 ° C. is issued. When the outside air temperature drops to 32 degrees, the set lower limit temperature is 28 ° C., so that no more temperature setting instruction is sent to the air conditioner, and the temperature setting 28 ° C. instruction is maintained.
Furthermore, since the set temperature is 28 ° C., the living room main unit 2 that is notified from the entrance cordless handset 2a that the outside air temperature has decreased to 28 ° C. gives an instruction of “cooling stop” to the air conditioner, A message is sent from the speaker of the communication section 9 "The air conditioner has stopped because the outside air temperature has dropped. Please open the window." By this operation, unnecessary cooling can be stopped. This message is stored in advance together with other messages in a voice memory (not shown) of the room master unit 2.

Thus, by controlling the indoor air conditioner based on the outside air temperature measured by the entrance cordless handset, the room temperature setting can be automatically changed according to the rise or fall of the outside air temperature. Therefore, it can be controlled to reduce the difference from the outside temperature, the visitor does not feel a sudden temperature change, and the visitor can perform air conditioning that is gentle to the visitor, and is effective in saving energy such as electric power.
Moreover, since the operation of the air conditioner is stopped when the outside air temperature becomes a predetermined temperature such as 28 ° C., for example, the operating cost of the air conditioner can be further reduced.

In this embodiment, the cooling by the air conditioner has been described as the control of the air conditioner, but the same control can be performed even in the heating control. For example, [heating / set temperature outside air temperature + 5 ° C./set upper limit temperature 22 ° C.] is set, the room temperature is set to 22 ° C., and if the outside air temperature is lower than 17 ° C., the room temperature setting is changed to 17 ° C. If it is ˜22 ° C., the control to set the room temperature to 22 ° C. can be performed to reduce the difference from the outside temperature, and the visitor does not feel a sudden temperature change and is friendly to the visitor. Air conditioning is possible, and it is effective for saving energy such as electric power.
In the case of a heating device, for example, it is possible to collectively control a plurality of air conditioning devices such as “floor heating operation when the outside air temperature is 10 ° C. or less, and combined use of the floor heating device and the air conditioner when the outside air temperature is 5 ° C. or less”.
Furthermore, by pressing and holding the call button 4 of the entrance cordless handset 1 and controlling the living room base phone 2, it may be announced from the cordless handset speaker that the current outside temperature is 35 ° C, compared with other thermometers. Thus, errors due to direct sunlight etc. of the thermometer can be confirmed.

Note that the management room master 19 has the same configuration as the room master 18 and will not be described.

The intercom system configured in this way operates and operates as follows. However, since the call from the collective entrance machine 17 and the operation to respond by the living room master unit 18 which are basic operations of the intercom are the same as the conventional ones, the description is omitted, and the flow of measurement information of the thermometer 23 and the information thereof are omitted. The control will be described.
First, similarly to the first embodiment, the setting unit 30 is operated by the resident, and the temperature of the air-conditioning device to be controlled is first set. For example, in the case of cooling setting, a setting of [cooling / outside temperature outside set temperature−5 degrees / set lower limit temperature 28 ° C.] is made. Then, the base unit control unit 31 of the room base unit 18 for which the temperature has been set operates according to the flow shown in FIG. 2 as in the first embodiment (the description is omitted).

As described above, by controlling the indoor air conditioner based on the outside air temperature measured by the collective entrance machine, the indoor temperature setting can be changed according to the rise or fall of the outside air temperature. Therefore, if the control is performed so as to reduce the difference from the outside air temperature, the visitor does not feel a sudden temperature change and air conditioning that is friendly to the visitor is possible, and it is also effective in saving energy such as electric power.
In addition, one thermometer is sufficient for multiple dwelling units, and cost increases can be suppressed, and it can be installed in a place where it is not exposed to direct sunlight or rain by incorporating it into the entrance hall to stabilize temperature measurement accuracy. it can.

<Third Embodiment Corresponding to Claim 3>
FIG. 4 is a block diagram showing a third embodiment of the intercom system, and shows an intercom system applied to a nurse call system installed in a hospital. As shown in FIG. 4, a nurse call cordless handset 35 installed for each bed for an inpatient to call a nurse, a corridor lamp 36 for displaying a call for each hospital room, and a nurse answering the call A nurse call parent device 37 installed in the nurse station and a controller 38 for controlling communication are provided. The nurse call cordless handset 35 is connected to the corridor lamp 36 for each hospital room via the transmission line L11, and the corridor lamp 36 is connected to the controller 38 via the transmission line L12. The nurse call parent device 37 is connected to the controller 38 by a transmission line L13.

The nurse call slave unit 35 includes a bed slave unit 40 having a call button 40a and a slave unit plate 41 that is installed near the bed and connects the bed slave unit 40. The slave unit plate 41 includes a microphone and a speaker. A handset communication unit 42, a thermometer 43 for measuring room temperature, and a handset control unit 44 for controlling the nurse call handset 35 are provided.
In addition, when the several nurse call subunit | mobile_unit 35 is installed in the hospital room, what is necessary is just to install at least 1 nurse call subunit | mobile_unit with a thermometer for every hospital room.

  The nurse call parent device 37 displays a call unit 46 having a speaker and a microphone, a call from the nurse call child device 35, and a display unit 47 that displays the temperature of a hospital room transmitted from the nurse call child device 35, an air conditioner, etc. Output terminal 48 for transmitting a signal to the air conditioner, a setting unit 49 for an operator to input operation parameters of an output signal such as an air conditioner temperature setting in advance, and a control unit for controlling the nurse call master unit 37 having a CPU (Master device control unit) 50 and an interface (master device IF) 51 for communicating with each nurse call slave device 35 are provided.

The intercom system configured in this way operates and operates as follows. However, the call from the nurse call slave unit 35 and the operation to respond by the nurse call master unit 37, which are basic operations of the intercom, are the same as the conventional ones, so the explanation is omitted, the flow of measurement information of the thermometer 43, and Control by information will be described.
First, the temperature of the air conditioner to be controlled is set. The setting unit 49 of the nurse call parent device 37 is operated by a hospital staff member such as a nurse, and for example, in the case of the cooling setting, the setting of “cooling / setting temperature room + 1 degree / setting lower limit temperature 28 ° C.” is made. This indicates that the cooling temperature in the corridor is set to 28 ° C., but priority is given to increasing the cooling temperature in the hospital room by 1 ° C.

  In this way, the base unit control unit 50 of the nurse call base unit 37 whose temperature has been set operates according to the flow shown in FIG. When the temperature setting of 28 ° C. is made by the setting unit 49 (S11), the control is started in response to the input of the room temperature information (S12). First, it is determined whether the room temperature exceeds 27 ° C. (28 ° C. minus 1 ° C.) (S13). If it exceeds, the temperature setting of the air conditioner that air-conditions the corridor is set to the hospital room temperature + 1 ° C. (S14). If it is 27 degrees C or less, it will be judged whether it exceeds 26 degrees C next (S15). If it exceeds 26 ° C, the air conditioner temperature is set to 28 ° C (S16). If it is 26 degrees C or less, a stop signal will be output and an air conditioner will be stopped (S17). The above control is periodically performed upon receiving the temperature information of the hospital room. The temperature information of the hospital room is transmitted from a plurality of hospital rooms to the nurse call parent device 37, and a control signal is output from the output terminal 48 to the corresponding air conditioner.

  By this control, for example, when the room temperature is 28 ° C., an instruction of a temperature setting of 29 ° C. is issued to the air conditioner, and control is performed to raise the temperature by 1 ° C. from the set temperature of 28 ° C. When the room temperature falls to 27 ° C., an instruction to set the original temperature at 28 ° C. is issued. When the hospital room temperature falls to 26 ° C., the lower limit set temperature is 28 ° C., so an “cooling stop” instruction is issued to the air conditioner to stop unnecessary cooling. At the same time, using the main unit speaker, a message is sent to the nurse station saying "The corridor air conditioner has been stopped because the room temperature has dropped," prompting the patient room temperature to rise.

  In this embodiment, the cooling by the air conditioner has been described as the control of the air conditioner. However, even the heating control can be similarly controlled. For example, “heating, set temperature, room temperature—1 ° C., set upper limit temperature, 24 ° C.” can be set. In addition, the bed handset 40 is configured such that when the call button 40a is pressed and held, the nurse call base unit 37 controls the speaker of the handset communication unit 42 to announce "the temperature of the current room is 28 ° C". You may do it. Furthermore, the room temperature may be displayed on the corridor lamp 36 based on the temperature information transmitted from the nurse call slave unit 35.

Thus, since the temperature of the hospital room can be measured and the air conditioner in the hallway can be controlled, the temperature setting of the hallway can be changed according to the temperature of the hospital room. Therefore, the temperature difference between the corridor and the hospital room can be controlled to be eliminated, air conditioning management that is gentle to hospitalized patients and visitors can be performed, and power consumption can be saved.
In addition, when the outside air temperature reaches a predetermined temperature such as 25 degrees, for example, the operation of the air conditioner is stopped, so that the operating cost of the air conditioner can be further reduced.
