Embodiment 1

[0056] In the related art, the commands are solidified inside the vehicle-mounted equipment, and the commands are actively sent by the vehicle-mounted equipment. On the whole, the methods used in related technologies have poor follow-up scalability.

[0057] Therefore, a communication method is provided in the following embodiments of the present invention, which can be applied to a handheld terminal. The method realizes the active detection of the hand-held terminal, facilitates the application of the detection party, and broadens the application range of the hand-held terminal.

[0058] Wherein, the form of the handheld terminal in this embodiment is not limited.

[0059] figure 1 It is a schematic flowchart of the communication method provided by the present invention. Such as figure 1 As shown, the communication method provided in this embodiment includes:

[0060] Step 101, the handheld terminal turns on the radio frequency field, so as to establish a near field commun...

Embodiment 2

[0082] figure 2 It is a schematic flowchart of a communication method provided by another embodiment of the present invention. The method provided in this embodiment can be applied to vehicle-mounted equipment, such as figure 2 As shown, the communication method includes:

[0083] Step 201, when the communication module of the vehicle-mounted device detects that the radio frequency field of the handheld terminal is disconnected, send an interrupt signal to the main control module of the vehicle-mounted device.

[0084] Step 202, the main control module of the on-vehicle device obtains the user instruction stored in the communication module according to the received interrupt signal.

[0085] When the communication module of the vehicle-mounted device detects that the radio frequency field of the handheld terminal is disconnected, that is, the communication module of the vehicle-mounted device detects that the communication connection with the handheld terminal is disconnec...

Embodiment 3

[0093] image 3 It is a signaling interaction diagram of a communication method provided by another embodiment of the present invention. This embodiment provides a communication method that can be applied to a communication system composed of a vehicle-mounted device and a handheld terminal. The communication method includes:

[0094] Step 301, the handheld terminal turns on the radio frequency field, so as to establish a near field communication connection with the communication module on the vehicle equipment.

[0095] Step 302, the handheld terminal sends a user instruction to the communication module of the vehicle-mounted device.

[0096] Step 303, receiving response information sent by the communication module of the vehicle-mounted device, where the response information is based on the response information of the communication module to the receiving result of the user instruction.

[0097] Step 304, the handheld terminal turns off the radio frequency field, so as to d...

Abstract

The present invention provides a communication method, a handheld terminal, a vehicle-mounted device, and a communication system, wherein the handheld terminal triggers the communication module to send an interrupt signal to the main control module by turning off the radio frequency field, thereby waking up the main control module to obtain and store in the communication module The user instruction, and the main control module will send the execution result of the user instruction to the communication module, and the handheld terminal can obtain the execution result of the user instruction stored in the communication module by turning on the radio frequency field again. It can be seen that the above method is based on the active communication mode of the handheld terminal. Thus, the application scenarios of the handheld terminal are broadened.

Description

technical field [0001] The invention relates to a communication method, a handheld terminal, a vehicle-mounted device and a communication system, specifically how to communicate with a main control module of the vehicle-mounted device through a near-field communication method, and belongs to the field of communication technology. Background technique [0002] With the development of intelligent terminal equipment, more and more vehicles have begun to install various on-board equipment, such as electronic toll collection system (ETC). [0003] The existing on-board equipment and external equipment generally can only be connected by contact communication through USB interface or plug-in IC card, or through long-distance wireless communication, such as through 5.8GHz frequency and roadside unit RSU (Road SideUnit, RSU for short). ) communication method for non-contact connection. For the USB interface reserved on the vehicle equipment, it is generally used for internal debuggi...
