The voice signal from the incoming operator is reproduced.

  The remote control learning mode button is a button for executing a remote control learning mode for storing all or a part of commands of the remote control of the air conditioner 16 installed in the house. If the remote control learning mode is executed only at the first time when the emergency call terminal device 13 is installed, the remote control learning mode is not executed unless the air conditioner 16 is replaced thereafter. For this reason, it is desirable to provide the remote control learning button on the side surface or the back surface of the device 13 in order to prevent erroneous operation.

  The remote control learning mode is a mode in which each command transmitted from the remote control of the air conditioner 16 is received by the remote control receiving unit 20 so that a command correspondence table is automatically created and stored in the RAM 26. The normal mode can be restored by operating the remote control learning button again.

  The RAM 26 stores the above-described command correspondence table. Also, reference environmental information acquired from the server 14 is stored. This environmental information is reference information for determining whether or not the house has an environment that may cause heat stroke. The ROM 27 stores various programs and parameters used for the programs in advance.

  The control unit 30 includes an environment determination unit 36. The environment determination unit 36 may cause heat stroke by comparing the reference environment information stored in the RAM 26 with the environment information including the current temperature and humidity in the house acquired from the temperature sensor 18 and the humidity sensor 19. Judge whether the environment is suitable. This determination is made every predetermined time.

  When determining that the environment is likely to cause heat stroke, the control unit 30 sets the mode of the air conditioner 16 such as “cooling” or “dehumidification” or a set temperature so as to be an optimal environment. Information on the determined mode and set temperature is converted into a command for the air conditioner 16 based on a command correspondence table stored in advance in the RAM 26, and the converted command is transmitted from the remote control transmission unit 21 to the air conditioner 16. To control.

  As shown in FIG. 3, the server 14 includes a modem 40, a display unit 41, an operation unit 42, a ROM 43, a RAM 44, and a control unit 45 that comprehensively controls them. The modem 40 includes a transmission unit 46 and a reception unit 47, converts data transmitted from the server 14 into a modem signal, and restores a modem signal received through the public line network 12 to data.

  The operation unit 42 includes a keyboard and a mouse. The ROM 43 stores various programs such as a program for creating reference environment information, parameters, and the like in advance. In response to receiving the emergency call signal, the server 14 starts the automatic response system, displays user information such as the user's address and telephone number on the screen of the display unit 41, and supports the emergency rescue system. To do. The RAM 44 stores reference environment information, personal information such as a user's health check result and physical condition, and is used as a working memory for executing the program.

  As the reference environment information, only one may be prepared and shared at each home, or a plurality of different pieces of information may be prepared for each home. When preparing more than one, for example, the physical work intensity (metabolic rate level) of home residents, health checkup results of persons with diseases that may affect the onset of heat stroke, and personal information such as physical conditions It is desirable to create it based on any one or a combination of them.

The physical condition is information on daily health management such as blood pressure, body temperature, and weight, which is food-backed to the emergency call center 11 by the cyclic medical examination service. The physical work intensity is classified by, for example, resting during sleep, low metabolic rate such as easy sitting and light work, persons accustomed to heat, persons not acclimatized to heat, and the like. Here, a person who has not acclimatized to heat means a person who has not been exposed to heat every day in the previous week.
The control unit 45 executes an emergency call monitoring program constituting the automatic response system, a program for creating standard environment information, and the like, and displays the screen of the display unit 41 based on information obtained from the emergency call terminal device 13. Control is performed so that the created reference environmental information is stored in the RAM 44. In addition, the stored reference environmental information is controlled to be sent to each emergency call terminal device 13.

  Digital weight scales, blood pressure monitors, height meters, and the like are connected to the emergency call terminal device 13 so that the information is automatically transmitted from the emergency call terminal device 13 to the server 14 as daily physical conditions. It may be configured. In this case, the server 14 creates environmental information based on the day for each house based on the physical condition, or corrects the environmental information based on the predetermined standard according to the physical condition on the day for each house. It may be configured to create environment information of different standards.

  Next, the operation of the above configuration will be described with reference to FIG. The emergency call terminal device 13 is installed at the user's home. At this time, initial setting for storing each command of the remote controller of the air conditioner 16 installed in the house is performed (S-1). The initial setting is to operate the remote control learning mode button. Thereby, the control part 30 of the emergency call terminal device 13 performs remote control learning mode. During the execution of this mode, the remote controller of the air conditioner 16 installed in the home is in the attitude toward the remote control receiver 20 of the emergency call terminal device 13, for example, by operating the operation button of the infrared remote controller, all or part Are sent in order. The control unit 30 creates a command conversion table based on the received command, and stores the created command conversion table in the RAM 26. When the remote control command storage operation is completed, the remote control learning mode button is operated again. Thereby, the control unit 30 executes the normal mode.

  Note that remote control data format setting means may be provided instead of the remote control command acquisition means described above. This means stores in advance the data format (signal format) of a plurality of infrared remote controls currently in use in the RAM 26, and inputs the manufacturer, model number, or information corresponding to these, so that Select the data format. In this case, it is preferable to provide a dip switch (Dual In-line Package switch) having a plurality of switches so that the manufacturer and the model number are specified by the combination of the on / off states of each switch. In this case, the remote control learning mode button can be omitted.

  Thereafter, the control unit 30 acquires and stores reference environmental information from the emergency call center 11 (S-2). In this case, the control unit 30 sends a request signal for obtaining the reference environmental information to the server 14 of the emergency call center 11. The request signal is transmitted at the beginning of installation and every predetermined time of the day. In response to receiving the request signal, the server 14 reads the reference environmental information stored in the RAM 44, and sends the read reference environmental information to the requesting emergency notification terminal device 13. The control unit 30 of the emergency call terminal device 13 updates and stores the acquired reference environmental information in the RAM 26.

  After acquiring the reference environmental information, the control unit 30 of the emergency call terminal device 13 acquires environmental information including the temperature and humidity measured by the temperature sensor 18 and the humidity sensor 19 at predetermined time intervals (S- 3). Then, the environment determination unit 36 compares the acquired environment information with the reference environment information read from the RAM 26, and determines whether the indoor environment is a dangerous environment that may cause heat stroke (S-4). ).

  When it is determined that the environment is not a dangerous environment (“N” side of S-4), a routine in which environmental information is acquired from the temperature sensor 18 and the humidity sensor 19 after a predetermined time has elapsed and compared with the reference environmental information. Return to (S-3).

  If it is determined that the environment is dangerous ("Y" side of S-4), it is determined whether the user is at home (S-5). In this determination, a determination result as to whether or not the user is at home is acquired from the home detection unit 23. When the determination result that the user is not at home is acquired (the “N” side of S-5), the temperature management of the air conditioner 16 is not required, so the current environmental information and the reference environmental information are stored for a predetermined time. The routine returns to the routine for comparison every time (S-3).

  When acquiring the determination result that the user is at home (“Y” side of S-5), it is determined whether or not the air conditioner 16 is operating (S-6). This is because a state notification command for notifying the state of the air conditioner 16 is read from the remote control conversion table, the command is transmitted from the remote control transmission unit to the air conditioner 16, and the current state is activated depending on whether or not a reply is possible. Determine whether. If it is determined that it is operating (“Y” side of S-6), information such as the current mode and set temperature is acquired from the returned information.

  When the air conditioner 16 is not operating (“N” side of S-6), in order to turn on the air conditioner 16, the start command is read with reference to the remote control conversion table, and the read start command is It transmits toward the air conditioner 16 from a remote control transmission part (S-7). If the air conditioner 16 does not have a status notification function, the determination of “Is the air conditioner activated?” (S-6) described in FIG. The procedure of “ON” (S-7) may be executed.

  After the operation of the air conditioner 16, the mode and setting control of the air conditioner 16 are performed. In this control, the mode of “cooling” or “dehumidification” is set, and a set temperature value, for example, “28 ° C.” that can remove a dangerous environment causing heat stroke is set, and the temperature value is set. The command is read from the command conversion table, and the read command is transmitted from the remote control transmission unit to the air conditioner 16 (S-8). Thereby, the air conditioner 16 controls the air conditioning so that the set temperature value is obtained in the set mode.

  The set temperature value to be set in the air conditioner 16 is determined in advance and stored in the RAM 26. This set temperature value needs to be changed according to the size of the room in the house, the performance of the air conditioner 16, the change in the temperature of the day, or the like. For this reason, instead of storing the set temperature value in the emergency call terminal device 13, a set temperature value different for each house is stored in the RAM 44 of the server 14 in advance, and the server 14 stores the set temperature value in the emergency call terminal device 13 every predetermined period. You may comprise so that it may send.

  Thereafter, the emergency call terminal device 13 acquires environmental information from the temperature sensor 18 and the humidity sensor 19 again after a predetermined time, and determines whether or not the environment is a dangerous environment based on the reference environmental information (S-9). ). If the environment is not dangerous ("N" side of S-9), the routine returns to the routine for obtaining the environmental information after a predetermined time has elapsed and comparing it with the reference environmental information (S-3).

  If it is determined that the environment is dangerous ("Y" side in S-9), an emergency call signal is sent to the server 14 (S-10). Thereby, an emergency call is made from the emergency call center 11 to a care center or a fire department. Thereby, support of emergency rescue activity can be performed rapidly. Instead of reporting to the server 14, the operator may be connected to the telephone 15 of the emergency reporting center 11 to notify the operator that it is dangerous by an automatic response.

  As the reference environment information, for example, as shown in FIG. 5, it is preferable to use a WBGT (Wet-Bulb Globe Temperature) value. The WBGT value is a heat index for evaluating thermal stress due to a hot environment, and is determined from relative humidity and dry bulb temperature. According to this, the range in which the WBGT value is “28” ° C. or higher (the range indicated by hatching) is a range (dangerous environment) that may cause heat stroke. The emergency call terminal device 13 acquires a correlation table between the humidity / temperature obtained from the temperature sensor 18 and the humidity sensor 19 and the WBGT value from the server 14, and when the WBGT value is “28” or more, Startup and temperature control may be performed.

  Note that it is desirable to control not only the temperature but also the air volume to control the air conditioner 16. For example, as described in the lower part of the figure, the range where the WBGT value is less than 25 ° C. is “caution”, the range from 25 ° C. to less than 28 ° C. is “caution”, the range from 28 ° C. to less than 31 ° C. is “strict alert” The above is divided into four ranges, “Danger”. In the “Caution” range, the air conditioner 16 is activated to set the set temperature value, and the air volume at this time is set to “Weak”. ”And“ strict warning ”, the air volume may be controlled to increase stepwise. In this case, it is preferable to notify the emergency call center 11 when it is determined that it is within the range of “danger”. Although the WBGT value is used as the reference environment information, the present invention is not limited to this, and other reference values may be used.

  By the way, when the emergency call terminal device 13 performs the temperature management of the air conditioner 16 at a predetermined set temperature, there are cases where it is desired to change the set temperature slightly because it is cold or conversely heated. Therefore, the emergency call terminal device 50 shown in FIG. 6 includes a set temperature value correction unit that corrects a predetermined set temperature value.

  The set temperature value correction means includes a + (plus) correction button 51, a − (minus) correction button 52, and a correction value display unit 53. By operating the + button 51 or the − button 52, the set temperature value is corrected by 1 ° C. to the + side or the − side. The correction value is displayed on the correction value display unit 53. In FIG. 6, reference numeral 54 is an emergency button, reference numeral 55 is a consultation button, reference numeral 56 is a microphone and speaker opening, reference numeral 57 is a cancel button, reference numeral 58 is an infrared signal transmission unit incorporating a remote control transmission unit and reception unit. Reference numeral 59 denotes a vent for a temperature sensor and a humidity sensor.

  As shown in FIG. 7, the control unit 60 corrects the set temperature value based on the correction value input from the correction value input unit 61 including the + button 51 and the − button 52, and becomes the corrected temperature. Thus, the command is transmitted to correct the set temperature of the air conditioner 16, and the corrected value after correction is displayed on the correction value display unit 53. If comprised in this way, when a person in the house is at home, the preset temperature of the air conditioner 16 can be corrected to a desired temperature.

  In each of the above embodiments, it is determined whether or not the environment is a dangerous environment based on the temperature and humidity in the house. However, if the difference between the outside air temperature and the room temperature is large, it is a burden on the body when going in and out. A sensor may be provided, and it may be determined whether or not the environment is dangerous by taking into account the outside air temperature obtained from the outside air temperature measurement sensor.

  In each of the above embodiments, the server 14 and the emergency call terminal device 13 are described as the emergency call system 10 connected by the public line network 12 including the exchange. However, the present invention is not limited to this, for example, a LAN It is good also as the emergency call system 10 connected by networks, such as.
