Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram for remote control in a gas air conditioner according to the present invention.

The microcomputer 10 is configured in the air conditioner for gas, controls all the electrical appliances constituting the gas air conditioner, transmits and receives control signals and data signals through the telephone line through the modem 16, and calls the DTMF receiver 18. Recognizes the key signal of the telephone input through the trunk line, transmits the guide voice stored in the guide voice output unit 20 through the telephone trunk line, and receives the device through the control output unit 12 when the remote control signal is received. To control and control.

Modem 16 is a control function of the telephone line to detect the incoming, outgoing and ringing tone of the telephone through the microcomputer 10 and the serial interface unit 14, remote control command, remote monitoring command, operation information data and abnormal occurrence It is to transmit and receive information data regarding.

The telephone line interface 24 is composed of a transformer (transformer) L, a relay RL, a plurality of zener diodes ZD1 and ZD2, capacitance C and varistor V to insulate the device from the telephone line. Matches the impedance.

The ring signal detection unit 26 converts the ringing tone received from the telephone line to a square wave signal so that the modem 16 can count the number of ringing tones.

In order to control the modem 16, the serial interface unit 14 matches the communication level of the serial communication terminal of the microcomputer and the serial communication terminal of the modem, and sets the control timing.

The DTMF receiver 18 decodes the dual tone multi-frequency signal input from the telephone line and inputs the information on the input key of the telephone to the microcomputer 10.

The guide voice output unit 20 outputs various guide voices embedded as the control signal of the microcomputer 10, and a ROM, a PROM, or the like is applied.

The control output unit 12 drives and controls the electrical equipment of the device by the control signal of the microcomputer 10.

The logical sum gate 22 connected to the output terminal of the microcomputer 10 and the output terminal of the modem 16 is a relay RL configured in the telephone line interface 24 by a signal input from the microcomputer 10 and the modem 16. By switching, the signal received from either the microcomputer 10 or the modem 16 is switched depending on whether the signal received from the telephone line is a normal telephone or a signal from a computer modem.

Referring to the operation of the remote control of the gas air conditioner according to the present invention configured as described above, first of all, the remote control of the gas air conditioner using the telephone remotely controls the gas air conditioner using the telephone (for example, operation, stop). Call the place where the gas air conditioner is installed (e.g., home or industrial) with an external telephone for air conditioning or heating operation selection). You will be called. At this time, the corresponding electrical equipment is operated by the control of the microcomputer configured in the air conditioner.

In the air conditioner for gas, the originator of the incoming call is checked through the telephone line, which is confirmed by the modem 16 in the air conditioner, and the originator of the call is made by the modem of the corresponding computer or simply by a telephone. It is to check whether the call is made.

If it is confirmed that the call originated through the phone, the microcomputer 10 turns on the incoming relay RL once again. This is because, due to the operation procedure of the modem 16, the incoming relay RL is automatically turned off after a predetermined time elapses if the call destination is not recognized, and the telephone connection is released. Therefore, the control of the incoming relay RL is configured to be performed at each of two output terminals of the modem 16 and the microcomputer 10 so that the call can be made from the telephone or through the modem of the corresponding computer. Remote control is possible.

When the call is re-called by the modem 16 after the incoming call is made, the microcomputer 10 of the air conditioner for the gas emits a guide voice necessary for remote control to the caller who has made the call (for example, "a gas air conditioner for the gas". Press 1 for cooling operation, 2 for heating operation, and 3 for stop operation ", etc.), and the caller inputs the corresponding control command by pressing the key of the phone according to the guide voice received through the handset. In the form of a dual tone multi-frequency (DTMF) signal of the input key is transmitted to the gas air conditioner through the telephone line, the microcomputer 10 of the gas air conditioner to decode and determine the received signal to the control output unit 12 By outputting the set control command, remote control of the gas air conditioner is performed.

After the gas air conditioner is operated by the remote control command as described above, the control result is transmitted to the caller with the set guide voice (for example, "the gas air conditioner is in the air conditioner"), and then the connected telephone is released. Let's do it.

Next, in the case of remote control of the gas / cooler using a computer modem, first, the central control computer (caller or remote control computer: not shown) and the modem 16 of the gas / cooler are initialized, respectively. The initial screen of the monitor configured as the control computer is activated.

When each initialization is made, when the central control computer makes a call through the telephone line to the gas air conditioner using the telephone call function of the modem, the modem 16 of the gas air conditioner connects to the telephone line after the preset telephone ring. In addition, the microcomputer 10 and the modem 16 determine whether the destination of the incoming call is the modem of the computer.

Therefore, the modem of the corresponding central control computer and the modem of the air conditioner and the air conditioner 16 are connected to each other according to a predetermined connection procedure, and when the connection is completed, a predetermined message (for example, CONNECT 9600, etc.) is transmitted from each modem. After outputting through the serial communication to the central control computer and gas air conditioner, the central control computer and gas air conditioner are connected in ON-LINE MODE to transmit and receive data with each other.

Therefore, when the remote control command selected by the sender is transmitted from the central control computer to the gas air conditioner in the set communication format, the gas air conditioner is controlled through the control output unit 12 of the gas air conditioner according to the control command, and the gas air conditioner The result controlled by is transmitted to the communication format set by the central control computer again, and when the transmission is completed, the connection state of the telephone is released.

On the other hand, in case of remote monitoring of gas and air conditioner using the modem of the corresponding computer, the telephone connection and disconnection with the remote control using the modem of the computer is the same. It is possible to make a request by telephone, or to make and receive a call from a gas-cooler or air conditioner to transmit and receive information data on the operation status by connecting a modem.

In addition, when the central control computer is automatically notified when an abnormality of the gas air conditioner occurs, the information on the abnormality occurring in the gas air conditioner after the procedure for the telephone connection between the modem of the central control computer and the gas air conditioner is established. When data is transmitted to the central control computer in the set communication format, the central control computer displays the received information data on the screen of the monitor and then releases the connected telephone.

As described above, the remote control, remote monitoring and automatic notification function using the modem of the telephone and the computer will be described in more detail with reference to the following examples.

First, referring to the flowchart of FIG. 2 for a remote control method of a gas air conditioner,

In step S100, the communication modem 16 of the gas / cooler control computer (for example, the microcomputer 10) is initialized, and the initialization is performed by the transmission speed, data bits, parity bits, stop bits, and the like of the modem 16. It is to set communication environment. When the setting of the communication modem 16 is completed, it is determined whether or not the control mode is selected in step S101. In this case, two control modes may be selected. It is a reception standby mode (remote control and monitoring standby) which waits to be turned on, and a data transmission standby mode in which abnormality occurs and data relating to operation information of a gas air conditioner is set at predetermined time intervals.

Therefore, when the call is received through the telephone line when the control mode is selected as the reception wait for the remote control and the monitoring waiting in step S102, whether the originator of the incoming call in step S103 is the modem of the corresponding computer. Or it distinguishes outgoing calls on phone.

At this time, when the calling party is a telephone in step S104, the call is re-initiated. In this case, if the calling party is not recognized by the operation procedure of the modem, the incoming relay RL is automatically recognized after a predetermined time has elapsed. This is because the phone is switched off and disconnected. Therefore, when the call is redialed, the guide voice set in the guide voice output unit 20 is sent to the call destination via the telephone line in step S105. In step S106, when the caller inputs a corresponding command by a combination of keys configured in the phone according to the guide voice transmitted through the telephone line, the microcomputer 10 receives it in step S107 after receiving it. According to the control command to output the control command to drive the device through the control output unit 12.

In step S108, the control is performed for driving the device, and when the control is completed, the guide voice output unit 20 is driven to notify the caller through the telephone line through the telephone line interface 24. The set guidance voice (for example, "heating or cooling operation", "operation stopped", etc.) is transmitted.

On the other hand, in the step (S103), if the classification of the source is a modem of the corresponding computer, not the telephone, the connection is made according to the corresponding connection procedure in step (S109), in which case the modem and the device of the corresponding central control computer The modem is connected directly and data can be sent and received. In step S110, when the modem is connected, the modem of the central control computer transmits a control command (or monitoring command) set to the modem 16 of the device, and the modem 16 of the device receives the serial interface unit. Input to the microcomputer 10 through 14, the microcomputer 10 determines the input signal in step S111 and outputs a predetermined control signal for controlling the device through the control output unit 12. In addition, in step S112, the control result of the device operated according to the control command is received, and the control result (or operation) is performed through the telephone line through the serial interface 14, the modem 16, and the telephone line interface 24. Information data) by the communication format set by the modem of the corresponding computer.

On the other hand, if it is selected to transmit the operation information (including abnormal information) in the control mode selection in the step (S101), or transmits the operation information data of the gas air conditioner for a certain time set to the standby mode for telephone call or gas In case of abnormality of air conditioner and air conditioner, the procedures for the two types of communication are the same as those of the modem of the central control computer and the modem of the equipment, and only the contents of the information data are different or the information data transmission / reception status changes. The communication format of data and information data due to an abnormality of the device may or may not be the same.

In step S113, the microcomputer 10 outputs the information on the set telephone number to the modem 16 via the serial interface unit 14, and the modem converts the information on the input telephone number into a dual tone multi-frequency. The telephone line is transmitted through the telephone line interface 24. The transmitted dual tone multi-frequency is connected to the corresponding telephone number via the telephone station, and the ringing tone is transmitted, and the modem of the central control computer corresponding to the telephone number receives the received ringing tone more than a predetermined number of times, in step S114. The phone is connected to the connected state. The connection is made between the modem of the gas / cooler and the modem of the central control computer according to a predetermined connection procedure. When a connection is established, when a predetermined message is recognized by each modem, the modems are connected to each other in an online mode to transmit and receive information data.

When the modem is connected in this way, in step S115, operation information including abnormal information generated during operation of the device is transmitted and received, and the received information data is displayed on the monitor screen of the central control computer.

In step S116, the completion guide voice for the operation control of the device by the telephone is transmitted in step S108, the control result is transmitted to the modem of the computer in step S112, or the abnormality information in step S115. When the transmission of the operation information including the is completed, the telephone connection state is released.

4 is for controlling the device through the telephone line to the normal telephone in the steps S101 to S108 and the step S116, after the telephone connection and disconnection with the apparatus is dialed in the step S300. When the dual tone multi-frequency is transmitted and the ringing tone received through the telephone line in step S301 is detected by the ring signal detector 26 at a predetermined number of times, the modem 16 and the serial interface unit 14 After the microcomputer 10 recognizes this, the microcomputer 10 drives the guide voice output unit 20 in step S302 to transmit the set voice through the telephone line interface 24 and the telephone line. The caller recognizes the guide voice through the handset of the telephone (for example, "press the air conditioner 1 for the air conditioner, press 2 for the heating operation, and press 3 for the operation", etc.) (S303). According to the voice guidance Perform the appropriate keystrokes on the keypad of the phone to deliver the command.

In step S304, the device performs the corresponding control according to the input key, and when the control is terminated, the voice prompting that the control is terminated (for example, "the air conditioner for gas is being cooled"). Received through the handset, and in step S305 to release the telephone connection state with the device.

Next, a flowchart of remote control of the central control computer connected to the modem of the device will be described with reference to FIG. 3.
