The number of the storage areas of the memory unit 22 is illustrated by way of example only. The memory unit 22 can be divided into a plurality of storage areas according to actual needs, and the number of divisions of the storage areas of the memory units is not limited herein.

The remote control method of the present invention is that the processing unit 20 executes a remote operation program stored in the first storage area 220, and displays an operation interface on the touch display unit 24 (S200), and its operation interface is as shown in FIG. 5. After the remote control operating program is executed and started, the remote control operating program then executes a system initialization program, and the remote control operating program transmits an initialization signal to the processing unit 20. When the processing unit 20 receives the initialization signal, the touch control mode is started. All electronic parts in the smart phone. After the touch smart phone completes the system initialization operation, the remote operation program transmits a connection signal to the processing unit 20, and the processing unit 20 performs a connection procedure according to the connection signal, so that the air conditioner and the touch smart The mobile phone is physically connected (S202).

After the foregoing connection procedure is executed, the physical connection between the first Bluetooth module 18 and the second Bluetooth module 26 is performed, and not only in this connection program, the remote operation program itself is preset at the same time. An application layer linking operation between the first Bluetooth module 18 and the second Bluetooth module 26 is performed.

Then, the processing unit 20 uses a check mechanism to check whether a state data transmitted by the air conditioner through the first Bluetooth module 18 is correct (S204), and the check mechanism is a bit (byte) for calculating state data by using an algorithm. Whether the total fit meets the predetermined value. The predetermined value is already stored in the second storage area 222 of the touch smart phone. For example, if the total bit of the state data is n bits, the calculation formula of the bit sum can be byte(n)+byte(n-1)...+byte(0), and then check The mechanism compares the calculated sum of the bits with a predetermined value.

In step S204, when the check result is incorrect, the touch smart phone transmits a request to resend the signal to the air conditioner to resend the status data, which may be caused by the air conditioner transmitting the status data. When the bit is lost, and the checking mechanism calculates the bit sum of the state data, the resulting bit combination result will not match the reservation.

In step S204, when the check result is correct, the user can use the connection air conditioner pattern 50 on the operation interface to perform the application layer synchronization connection between the first Bluetooth module and the second Bluetooth module 26, so as to be instant.

Wait. The remote control program will also store the updated current state of the air conditioner in the second storage area 222 to update the previously stored air conditioner setting status. The update function mentioned above can also be implemented by hardware, for example, an update button (not shown) is preset at any position of the touch smart phone.

The user selects the lock/unlock pattern 52 through the operation interface to generate a lock signal, and transmits the lock signal to the processing unit 20 to put the touch smart phone into a lock mode (S208). When the touch smart phone is in the lock mode, the processing unit 20 performs a synchronization process and a check mechanism for a fixed period of time, and then transmits a fixed information of the air conditioner to the touch display unit for display through the Bluetooth signal. (S210). In step S210, the checking mechanism is like step S204. When the checking result is correct, the processing unit 20 transmits a fixed information of the air conditioner to the touch display unit for display through the Bluetooth signal. The above fixed time can be set by the user through other function patterns 60, for example, setting the synchronization program every second or every minute, which is easily understood by those skilled in the art. The above fixed information refers to information that does not require additional settings by the user, as shown in Figure 6. For example, indoor temperature, outdoor temperature, preset shutdown time, and current output of the air conditioner.

Please refer to FIG. 1 and FIG. 3 at the same time. FIG. 3 is a flowchart of the pairing modification method of the present invention. The pairing modification method of the present invention transmits the appliance pairing data stored in the memory unit 102 to the touch smart phone (S300) through the first Bluetooth module 18 through the Bluetooth signal, and then the processing unit 20 detects whether to receive the data. To a pairing modification signal transmitted by the air conditioner (S302), when the processing unit 20 receives the pairing modification signal, the remote operation program executes a pairing modification procedure (S304), and conversely, when the processing unit 20 does not receive When the pairing modification signal is reached, the touch smart phone will maintain the lock mode (S306).

Then, the remote control operation program checks whether the appliance pairing data transmitted by the air conditioner is the same as the first pairing data in the second storage area 222 (S308). When the check result is the same, the remote operation program performs setting one second. The paired data is overwritten and the first paired data is overwritten (S310). At this time, the processing unit 20 transmits the second paired data to the air conditioner using the Bluetooth signal (S312), and when the check result is different, the pairing modification program is left.

In step S312, after receiving the second paired data, the first Bluetooth module 18 of the air conditioner transmits the received second paired data to the memory unit 102 and overwrites the original appliance pairing data.

In summary, the remote control device of the present invention can remotely control the electrical device through the operation of the remote control operating program, and when the remote remote control device has activated the lock mode, the remote remote control device can still pass the Bluetooth mode. The group synchronously receives the latest status of the electrical equipment.
