Description

Control method of intelligent terminal and intelligent terminal
Technical Field
The invention relates to the technical field of wireless communication, in particular to a control method of an intelligent terminal and the intelligent terminal.
Background
NFC (Near Field Communication) technology is derived from RFID (Radio Frequency Identification) technology, proposed by panasonic, philips and nokia, and enables two electronic devices to directly perform short-range Communication. NFC is a short-range high-frequency radio technology operating at 13.56MHz with an effective communication distance of within 10 cm. The basic working principle is that the NFC master device side provides a radio frequency field in the whole communication process, and the NFC master device can select one of transmission speeds of 106kbps, 212kbps, 424kbps and the like to transmit data to another device. The other device, called the NFC slave side, does not have to generate a radio frequency field but uses a load modulation technique, i.e. transmits data back to the initiating device at the same speed.
With the popularization of contactless payment, more and more smart terminals having an NFC function are available, and the NFC function of the smart terminal can not only realize a function of a PICC (proximity card or contactless analog card), but also realize a function of a PCD (proximity networking device, contactless card reader). At present, most of the interactive interfaces of the smart terminal are not free from a CTP (Capacitive touch panel), such as a smart phone, a smart POS (Point of away, disappearing terminal), and the like, that is, more and more devices may have two functions of a CTP and an NFC. As described above, the working frequency of NFC is 13.56MHz, the data rate is in the range of 106 KHz-424 KHz, and the frequency of CTP emission driving signals is also around 50 KHz-300 KHz. When the CTP plane is closer to the plane of the NFC antenna, for example, the NFC antenna is placed right below the CTP plane, the transmission signal of the CTP is easily coupled by the NFC antenna, which interferes the reception signal of the NFC, and affects the reception signal, especially some NFC modulation methods with a relatively low modulation depth cause communication failure or communication efficiency reduction.
In the practical design, along with the miniaturization of the terminal, a large clean space is difficult to find out to place the NFC antenna, and the NFC antenna is designed below the screen, namely below the CTP, which is doubtful.

Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
Fig. 1 shows a flowchart of a control method of the intelligent terminal of the present embodiment. Wherein, intelligent terminal is the master unit side, includes: NFC chip and CTP. The control method comprises the following steps:
step 101, determining whether the starting condition of the NFC chip is met, if so, executing step 102, otherwise, executing step 101 again;
the starting condition is that a triggering instruction is received, and the triggering instruction can be sent by a user through operating a button or other controls arranged on the main equipment side, or generated and sent to the main equipment side after being triggered by other equipment or programs.
Step 102, disabling CTP and starting NFC chip to carry out NFC communication, and then executing step 103;
step 102 includes disabling CTP all the way when the NFC chip performs NFC communication.
The forbidden CTP is the function of closing CTP emission driving signals or stopping the work of the CTP chip.
The NFC communication provides a radio frequency field for the master device side, detects the slave device side in the radio frequency field, and when detecting the slave device side in the radio frequency field, the master device side may specifically repeat a request command in a polling manner, and search for a response signal sent back from the slave device side. When the master device side receives the response signals of the plurality of slave device sides, collision processing is carried out, and one slave device side is selected from the plurality of slave device sides to be used as the slave device side for carrying out NFC communication. When the main device side receives a response signal of the slave device side, the slave device side is activated, and then reading and writing are carried out on the slave device side.
Step 103, after the master device side and the slave device side complete sending and receiving of data frames or when the NFC communication exceeds a time threshold, turning off the NFC chip and enabling the CTP.
The control method of the embodiment enables the intelligent device to be the master device side, and disables the CTP when the starting condition of the NFC chip is met, so that the CTP does not interfere with the NFC communication, and the effectiveness of the NFC communication is ensured.
Example 2
In the above embodiment 1, when the duration of one NFC communication process is long, CTP is likely to fail to respond for a long time, and this embodiment is further optimized for this problem.
The control method of the present embodiment is basically the same as that of embodiment 1, and the main differences are that: the control method of the present embodiment is shown in fig. 2, and includes:
step 201, determining whether the starting condition of the NFC chip is met; if yes, go to step 202, otherwise go to step 201 again;
the step of determining whether the starting condition of the NFC chip is satisfied is the same as that in step 101 in embodiment 1, and therefore is not described again.
At step 202, CTP is intermittently disabled.
The intermittent disabling of CTP specifically includes that, in the whole NFC communication, the transceiving time of each pair of data frames of the NFC chip is divided into four time periods, as shown in fig. 3:
the first time period is a time period for the master device side to send a data frame, namely a time period for the master device side to send a data frame to the slave device side;
the second time period is a time interval from the sending of the data frame by the master device side to the receiving of the data frame, namely, a time interval from the sending of the data frame by the master device side to the receiving of the data frame sent by the slave device side;
the third time period is a time period when the master device side receives the data frame, namely the time period when the master device side receives the data frame sent by the slave device side;
the fourth time period is a time interval from the time when the master device side receives the data frame to the time when the master device side sends the data frame, that is, a time interval from the time when the master device side receives the data frame sent by the slave device to the time when the master device side sends the data frame.
The CTP is intermittently disabled in the above-described period of transmitting and receiving the data frame, and specifically, any one of the following A, B and C modes may be adopted.
Mode A:
in order to enable the CTP to respond to the external key input and improve the user experience of the CTP, the a mode may be selected. As shown in fig. 4:
during the first time period and the third time period, the CTP is disabled, and during the second time period and the fourth time period, the CTP is enabled.
Mode B:
according to NFC communication, the second time period has the maximum time limit, generally not more than 1ms, CTP is enabled in the second time period, and the difficulty is high. CTP may be relatively easily enabled without a maximum time limit during the fourth time period. To disable CTP for the second time period, the B mode may be selected. As shown in fig. 5:
during the first time period, the second time period and the third time period, the CTP is disabled, and during the fourth time period, the CTP is enabled.
Mode C:
in the first time period, the signal strength is strong and is not easily interfered by CTP. In the third time period, the signal strength is weak and is easily interfered by CTP. To enable CTP in the first and second time periods, the C mode may be selected. As shown in fig. 6:
during the third time period, the CTP is disabled, and during the first time period, the second time period and the fourth time period, the CTP is enabled.
The control method of the embodiment can ensure that the CTP does not interfere with the NFC communication by intermittently disabling and enabling the CTP after the NFC chip is confirmed to be started, can also solve the problem that the CTP does not respond for a long time in the NFC communication, and improves the user experience.
Example 3
Fig. 7 shows a flowchart of a control method of the smart terminal of the present embodiment. Wherein, intelligent terminal is the slave unit side, includes: NFC chip and CTP. The control method comprises the following steps:
step 301, determining whether a starting condition of the NFC chip is satisfied; if yes, go to step 302; if not, executing step 301 again;
the starting condition is that a radio frequency field is detected.
Step 302, disabling CTP and starting NFC chip for NFC communication, and then executing step 303;
step 302 includes disabling CTP all the way while the NFC chip is performing NFC communication.
The disabled CTP in this step is substantially the same as the disabled CTP in step 102 in example 1, and thus, the description thereof is omitted.
The NFC communication is that after the slave device side is activated by a radio frequency field, the slave device enters an Idle state from a Power Off state; after receiving the effective command sent by the master equipment side, the slave equipment side enters a Ready state; when the slave device side is selected by the master device side, the slave device side enters an Active state; after entering the state, the slave device side is read and written by the master device side; when the slave receives a Halt command, the slave enters a Halt state.
Step 303, when it is detected that the radio frequency field is turned off or the NFC communication exceeds a time threshold, turning off the NFC chip and enabling the CTP.
The control method of the embodiment enables the intelligent device to be the slave device side, and disables the CTP when the starting condition of the NFC chip is met, so that the CTP does not interfere with the NFC communication, and the effectiveness of the NFC communication is ensured.

In another specific implementation manner of this embodiment, the control module 404 is configured to intermittently disable the CTP402 when the NFC chip 401 performs the NFC communication.
Intermittently disabling CTP402, including: in the first and third time periods, CTP402 is disabled.
The first time period is a time period for the master device side to send a data frame;
