Communication method and communication system

The invention relates to the field of communication, in particular to a communication method and a communication system.

With the popularity of mobile terminals and Global Positioning System (GPS) technology, more and more users can use GPS-equipped mobile terminals for positioning, especially mobile phones, tablets, etc. with GPS modules installed. . Ordinary users carry such mobile terminals and achieve positioning by communicating with GPS satellites in a relatively empty environment. Common positioning methods are based on mobile network, GPS, and assisted GPS (A-GPS). Based on the mobile network, the mobile terminal needs to be able to access a wireless communication network such as the Global System of Mobile communication (GSM), and the location of the connected cell base station substantially corresponds to the location of the mobile phone, so the positioning of the method is The accuracy depends on the coverage radius of the cell base station where the mobile terminal is located, ranging from a few hundred meters to several tens of kilometers. The GPS-based positioning technology is that the mobile terminal receives the positioning signals of 24 GPS satellites around the world, and uses the parameters transmitted by 3 to 4 satellites to realize the positioning of the mobile terminal. The A-GPS-based positioning technology is essentially the same as the GPS positioning technology, except that the step of searching for a satellite transmits the connected cell base station message to the location service platform by using the mobile network, and the location service platform transmits the cell base station to the mobile terminal. GPS satellite messages eliminate the heavy steps of mobile terminals searching for satellites.

Generally speaking, based on the above-mentioned positioning technology, the positioning of the mobile terminal needs to be based on the following conditions: First, the mobile network-based positioning technology requires the mobile terminal to connect to a mobile network such as GSM; second, based on GPS, The positioning technology of A-GPS requires the mobile terminal to be equipped with a GPS module. Thirdly, the positioning technology based on GPS and A-GPS requires the mobile terminal to be in a relatively open outdoor area or in an area without high-rise buildings.

Although the GPS positioning technology has brought great convenience to people's transportation, there are still many small-scale positioning application scenarios in real life that cannot be solved by using GPS technology. This type of demand does not require global positioning. It only needs to control indoor and underground locations with a small positioning accuracy (for example, within 50 meters), such as underground parking lots, shopping malls, shopping malls, shopping malls, or shopping malls. Park visit guides, etc. Due to the limitations of the above three conditions, it is impossible to locate in large urban buildings and underground parking lots that cannot be covered by mobile network signals and GPS signals. Even if the GPS signal can be covered, many users who use the old mobile phone cannot enjoy the GPS positioning service because they do not have a GPS positioning module.

Querying the terminal or the like; more preferably, it is a card-swapping terminal installed on a mass transit vehicle (such as a bus). In the present embodiment, only the above several cases are taken as an example for exemplary explanation. In the embodiment, the process of implementing the push of the target message with the corresponding first communication terminal by using the radio frequency technology is shown in FIG. 1 : Step 101: setting the identification information of each installed first communication terminal, and setting The good identification information is stored in the first communication terminal; in this embodiment, the identification information of the first communication terminal can be selected and set according to actual conditions, for example, it can be uniquely set by the terminal manufacturer when it is shipped from the factory. The number, etc., may also be a uniquely numbered identification message for each first communication terminal according to a certain rule; the setting manner may be selected according to the actual situation, and will not be described in detail here; Step 102: According to each The identifier message of the first communication terminal is configured to obtain the first communication terminal identifier message and the target message index table corresponding to the target message corresponding to each first communication terminal, and the obtained first communication terminal identifier message and the target message index table are stored.

Embodiment 2:

In the communication system shown in FIG. 2 to FIG. 5 of the first embodiment, the radio communication between the second communication terminal and the first communication terminal is involved, and the second communication terminal and the first communication terminal in this embodiment are used. Both can send or receive data at multiple different addresses through multiple different frequency points. Therefore, in the process of RF communication between the two, there must be frequency of data communication and how to improve the anti-interference ability in the communication process. problem.

In order to solve the above problem, in the embodiment, when the first communication terminal and the second communication terminal perform radio frequency communication, when one party sends the relevant radio frequency data to the other party, When the RF data sender sends a synchronization message including the sender's RF channel identifier and the transmission data address by using the preset synchronization address on the preset synchronization RF channel, the RF data receiver is in the preset synchronization RF signal. The channel receives the synchronization message from the preset synchronization address, and obtains the RF channel identifier and the transmission data address of the sender from the synchronization message, and obtains the RF channel of the sender according to the obtained RF channel identifier of the sender; the RF data receiver The sender RF channel receives radio frequency data from the transmission data address.

That is, in the embodiment, in the process of radio frequency data communication between the first communication terminal and the second communication terminal, the sender may send a synchronization message to the receiver by sending a synchronization message to inform the receiver of the radio frequency used. The channel and the transmission of the data address can greatly improve the reliability of data transmission and the anti-interference ability and effectiveness during data transmission.

In this embodiment, the sender's RF channel identifier and the transmission data address may use random data. In this case, the manner of synchronizing the message is as shown in FIG. 6, and the synchronization message is composed of a message direction field and a message type field. , message length field, message data field, message verification field. Among them, the message data field contains a random data. When sending a synchronization message and performing radio frequency data interaction, a packet transmission mode may be adopted. At this time, the sender divides the synchronization message and the radio frequency data to be transmitted, and adds a data type field to the split data packet. The last packet identification field and the data packet identification field form a data packet. The sender will send the formed data packet from the preset synchronization address on the synchronous RF channel. In this case, the RF data sender and the RF data receiver respectively perform random data in the synchronization message. The irreversible transformation obtains the corresponding sender's RF channel identification and transmission data address.

In this embodiment, sending and receiving messages at different frequency points and addresses may also use a sender to select a transmission frequency point, and then insert a group of address information of a target to be received in the transmission message, and send the band at the selected transmission frequency point. The message with the address message, the receiving end extracts the address message in the message after receiving the message at the frequency point, and outputs the message if the address message is a valid address (for example, the receiving end includes the receiving end), otherwise the message is not output. Certainly, sending and receiving messages at different frequency points and addresses may also be implemented in other manners, and details are not described herein again.

In this embodiment, the preset synchronous radio channel may include at least two, and the radio frequency data sender may send the same synchronization message on at least two of the synchronous radio channels, and the setting scheme may avoid When the preset synchronous radio channel receiving state is not good, the synchronization message can be received from other preset synchronization channels, thereby further improving the reliability of data transmission.

In this embodiment, the RF data sender can repeatedly send the synchronization message in the same preset synchronous RF channel, and the number of repeated transmissions and the time interval can be set according to actual conditions, so as to ensure that the RF data receiver with slow processing speed is also It can completely receive the RF data sent by the sender.

In this embodiment, the radio frequency channel identifier may be at least one of an RF frequency point, a frequency band, a logic signal channel, and a channel.

When the first communication terminal 100 is a radio frequency data transmitting party, The first radio frequency communication module 120 of the communication terminal 100 associates relevant radio frequency data (eg, target message, first communication) Before sending the identification message of the terminal 100 to the second communication terminal 200, the synchronization message including the radio channel identifier and the transmission data address used by the preset synchronization address is transmitted on the preset synchronization radio channel; the second communication terminal The second radio frequency communication module 220 is configured to receive the synchronization message from the preset synchronization address on the preset synchronization radio channel, and obtain the radio channel identifier and the transmission data address used by the first communication terminal 100 from the synchronization message, according to the acquisition. The RF channel identifier is obtained by the RF channel used by the first communication terminal 100. The RF channel receives the RF data broadcast by the first communication terminal 100 by the first RF communication module 120 from the transmission data address. Of course, the first radio frequency communication module 120 can also send the radio frequency data to the second communication terminal in a point-to-point manner. When the radio channel identification and the transmission data address adopt the random data shown in FIG. 6, the first radio frequency communication module 120 and the second radio frequency communication module 220 respectively perform irreversible transformation on the random data to obtain a corresponding sender radio frequency. Channel identification and sending data address.

For the same reason, in order to further improve the reliability of data transmission, the first radio frequency communication module 120 of the first communication terminal 100 in this embodiment can also broadcast the same synchronization message on at least two synchronous radio channels. At the same time, in order to avoid the problem that the receiver of the second communication terminal 200 fails to receive data due to the slow processing speed, the first radio frequency communication module 120 of the first communication terminal 100 in this embodiment is more The same preset synchronous radio channel repeatedly transmits the synchronization message and then transmits the corresponding radio frequency data.

When the second communication terminal 200 is a radio frequency data sender, the second radio frequency communication module 220 transmits the related radio frequency data by using a preset synchronization address on the preset synchronization radio frequency channel before transmitting the relevant radio frequency data to the first communication terminal 100. Synchronization message of the radio channel identification and the transmission data address adopted; the first radio communication module of the first communication terminal 100 The preset synchronization radio frequency channel receives the synchronization message from the preset synchronization address, obtains the radio channel identifier and the transmission data address used by the second communication terminal 200 from the synchronization message, and obtains the sender according to the obtained radio channel identifier. The radio frequency channel receives the radio frequency data sent by the second communication terminal 200 from the transmission data address by using the radio frequency channel.

Similarly, in the embodiment, when the radio frequency channel identification and the transmission data address use the random data shown in FIG. 6, the first radio frequency communication module 120 and the second radio frequency communication module 220 respectively respectively use the random data. Perform irreversible transformation to obtain the corresponding sender's RF channel identification and transmission data address.

In the meantime, in order to further improve the reliability of the data transmission, the second radio frequency communication module 220 of the second communication terminal 200 in this embodiment can also broadcast the same synchronization message on at least two synchronous radio channels. At the same time, in order to avoid the problem that the receiver of the second communication terminal 100 fails to receive data due to the slow processing speed, the second radio frequency communication module 220 of the second communication terminal 200 in this embodiment is more The same preset synchronous radio channel repeatedly transmits the synchronization message and then transmits the corresponding radio frequency data.

In the module 140, the first communication terminal 100 reads the data message stored in the first storage module 140 by using the first main control module 110; Step 703: The first communication terminal 100 is first The RF communication module 120 sends a synchronization message at a preset synchronous RF frequency point. Step 704: The first main control module 110 of the first communication terminal 100 performs irreversible transformation on the random data carried by the synchronization message, and generates a broadcast corresponding to the transformation result. The data transmission frequency of the data (ie, the sender RF channel) and the broadcast data transmission address (ie, the transmission data address); meanwhile, the second master module 210 of the second communication terminal 200 includes the received synchronization message.
