Instruction information transmission and reception methods and devices thereof

A method for receiving instruction information, comprising:

• sending operation description information of an operation corresponding to first instruction information to a sending device or a mobile terminal, so that the mobile terminal indicates the operation description information to a user, and so that the mobile terminal generates the first instruction information and/or second instruction information according to input information of the user and/or the operation description information, wherein
• the operation description information comprises at least one of the following:
• code information, time information, address information, user information, account information, commodity information, and payment information;
• receiving a first transmission signal that is sent by the sending device and carries the first instruction information, wherein the sending device is connected to a data transmission interface of the mobile terminal, so that the sending device acquires a first differential signal that is output by the mobile terminal from the data transmission interface and carries the first instruction information and/or the second instruction information, which specifically comprises:
• acquiring the first differential signal if a recognition signal indicating that a distance between the mobile terminal and a receiving device is smaller than a preset distance threshold is received;
• and/or
• acquiring the first differential signal if a trigger signal sent by the receiving device is received, wherein
• the second instruction information is used to instruct the sending device to send the first transmission signal, wherein the first transmission signal is a light signal or a sound wave signal;
• and
• performing an operation corresponding to the first instruction information according to the received first transmission signal.

A device for sending and receiving instruction information,

• the device for sending instruction information comprising:
• a first acquiring unit, configured to acquire a first differential signal that is output from a data transmission interface of a mobile terminal and carries first instruction information and/or second instruction information, wherein the first instruction information is used to instruct a receiving device to perform an operation corresponding to the first instruction information, and the second instruction information is used to instruct to send the first instruction information to the receiving device;
• a first transmitting unit, configured to generate, according to the acquired first differential signal, a first transmission signal that carries the first instruction information, and send the first transmission signal to the receiving device, wherein the first transmission signal is a light signal or a sound wave signal;
• a receiving unit, configured to receive the first instruction information and/or operation description information of the operation corresponding to the first instruction information, wherein the operation description information comprises at least one of the following:
• code information, time information, address information, user information, account information, commodity information, and payment information;
• a storing unit, configured to:
• when the first instruction information is received, temporarily store the received first instruction information locally;
• and/or
• a third transmitting unit, configured to:
• when the operation description information is received, transmit the operation description information to the mobile terminal, so that the mobile terminal indicates the operation description information to a user, and so that the mobile terminal generates the first instruction information and/or the second instruction information according to input information of the user and/or the operation description information, wherein
• the first acquiring unit comprises a third acquiring module, configured to acquire the first differential signal when a recognition signal indicating that a distance between the mobile terminal and the receiving device is smaller than a preset distance threshold is received, and/or acquire the first differential signal when a trigger signal sent by the receiving device is received;
• the device for receiving instruction information, comprising:
• a first receiving unit, configured to receive a first transmission signal that is sent by a sending device and carries first instruction information, wherein the sending device is connected to a data transmission interface of a mobile terminal, so that the sending device acquires a first differential signal that is output by the mobile terminal from the data transmission interface and carries the first instruction information and/or second instruction information, wherein the second instruction information is used to instruct the sending device to send the first transmission signal, wherein the first transmission signal is a light signal or a sound wave signal, which specifically comprises:
• acquiring the first differential signal if a recognition signal indicating that a distance between the mobile terminal and the receiving device is smaller than a preset distance threshold is received;
• and/or
• acquiring the first differential signal if a trigger signal sent by the receiving device is received;
• a processing unit, configured to perform an operation corresponding to the first instruction information according to the received first transmission signal;
• and
• a second transmitting unit, configured to send operation description information of an operation corresponding to the first instruction information to the sending device or the mobile terminal, wherein the operation description information comprises at least one of the following:
• code information, time information, address information, user information, account information, commodity information, and payment information, so that the mobile terminal indicates the operation description information to a user, and so that the mobile terminal generates the first instruction information and/or the second instruction information according to input information of the user and/or the operation description information.
