All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a terminal control method, which is applied to an electronic device, and includes:
the first signal is a Time Division Duplex (TDD) signal, and the receiving and transmitting of the first signal are in different Time slots of the same frequency channel, and are separated in Time according to the operating property of the TDD signal, that is, the transmitting and receiving of the first signal are separated in Time.
The first radio frequency circuit may be a radio frequency circuit of a wireless network, the radio frequency circuit of the wireless network and a main radio frequency (fourth generation mobile communication technology 4G, etc.) circuit usually adopt an independent antenna design, that is, the first radio frequency circuit receives and transmits the first signal through a first antenna connected thereto, the main radio frequency circuit receives and transmits the signal through a second antenna connected thereto, the first antenna and the second antenna are respectively and independently arranged in a terminal, and when the distance between the arrangement position of the first antenna or the second antenna and the position of the memory card is smaller than a preset distance, if a frequency range when the radio frequency circuit receives the signal includes a frequency doubling point of a frequency when the memory card performs read-write operation, the read-write operation of the memory card will generate interference on the signal received by the radio frequency circuit; and if the frequency range of the radio frequency circuit during signal receiving does not contain the frequency doubling point of the frequency during the read-write operation of the memory card, the read-write operation of the memory card does not interfere with the signal receiving of the radio frequency circuit.
wherein the isolation of the second antenna is greater than the isolation of the first antenna.
In this embodiment, the second rf circuit may be a main rf circuit, and is connected to the second antenna, and performs signal transmission through the second antenna. The electronic device determines whether the interference information meets a first preset condition according to the acquired interference information, where the first preset condition may be: the method comprises the steps that the read-write operation of a memory card generates interference on the reception of a first signal of a first radio frequency circuit, namely when the read-write operation of the memory card is determined to generate interference on the reception of the first signal, the first radio frequency circuit is controlled to be electrically connected with a second radio frequency circuit, the first signal is received through a second antenna connected with the second radio frequency circuit until the read-write operation of the memory card stops, the connecting antenna of the first radio frequency circuit is switched back to the first antenna, and the first signal is sent and received through the first antenna. When the first radio frequency circuit transmits the first signal, the first signal is a strong signal and is not interfered by the memory card during read-write operation, so that the first radio frequency circuit still works through the first antenna connected with the first radio frequency circuit when the first radio frequency circuit transmits the first signal.
If the interference information does not meet the first preset condition, that is, it is determined that the read-write operation of the memory card does not interfere with the reception of the first signal, the first radio frequency circuit still transmits and receives the first signal through the first antenna without switching the connection antenna of the first radio frequency circuit.
It should be noted that the isolation of the second antenna is greater than that of the first antenna, so as to ensure that the read-write operation of the memory card does not interfere with the reception of the first signal any more after the first radio frequency circuit is connected to the second antenna of the second radio frequency circuit when receiving the first signal. Optionally, the distance between the second antenna and the memory card is greater than the distance between the first antenna and the memory card, so that it can be ensured that the isolation of the second antenna is greater than that of the first antenna, and the second antenna is not affected by data transmission of the memory card, and has good receiving performance. When the memory card does not perform read-write operation and data transmission, the first radio frequency circuit receives and transmits the first signal through the first antenna.
According to the embodiment of the invention, under the condition that the interference of the read-write operation of the memory card on the reception of the first signal is determined, the first radio frequency circuit is controlled to receive the signal through the second antenna of the second radio frequency circuit, so that the first radio frequency circuit is switched to the second antenna with better receiving performance when receiving the first signal, the interference of the data transmission of the memory card on the reception of the first signal is reduced, and the quality of the received signal is effectively improved.
Specifically, the first radio frequency circuit includes a first switch, the first radio frequency circuit may be electrically connected to the first antenna through the first switch, and the first radio frequency circuit may be electrically connected to the second radio frequency circuit through the first switch.
The step 102 may include: when the first radio frequency circuit receives the first signal, the first radio frequency circuit is controlled to be electrically connected with the second radio frequency circuit through the first change-over switch; and when the first radio frequency circuit sends the first signal, controlling the first radio frequency circuit to be electrically connected with the first antenna through the first selector switch.
In this embodiment, the first switch may be a double-pole double-throw switch, and the first rf circuit and the second rf circuit can be electrically connected through the first switch. The first switch includes: when the first switch works in the first state, the first radio frequency circuit is electrically connected with the first antenna through the first switch, and signals are transmitted or received through the first antenna; when the first switch works in the second state, the first radio frequency circuit is disconnected from the first antenna and is electrically connected with the second radio frequency circuit, and the first radio frequency circuit receives and sends signals through the second antenna connected with the second radio frequency circuit.
In this embodiment, when it is determined that the read-write operation of the memory card interferes with the reception of the first signal, the switching of the connection antenna of the first radio frequency circuit is controlled by controlling the operating state of the first switch, so that the first radio frequency circuit is switched to the second antenna with better reception performance when receiving the first signal, thereby reducing the interference of the data transmission of the memory card on the reception of the first signal and effectively improving the quality of the received signal.
Specifically, as shown in fig. 2, the step 101 may include:
taking the first radio frequency circuit as the radio frequency circuit of the wireless network as an example, when the memory card performs data transmission, the interference degree of the memory card to the receiving sensitivity of each channel of the wireless network is different, and when the interference state of the memory card when the read-write operation is performed on the first signal is obtained, the channel of the first radio frequency circuit which is currently working needs to be judged first.
when the first radio frequency circuit receives and sends a first signal through a first antenna, if the distance between the first antenna and the memory card is smaller than a preset distance, the read-write operation of the memory card interferes with the receiving sensitivity of a current working channel of the first radio frequency circuit, and if the interference degrees are smaller, the switching of the working antenna of the first radio frequency circuit does not need to be controlled, so that the interference degree of the read-write operation of the memory card on the receiving sensitivity needs to be judged.
The interference degree of the memory card to the receiving sensitivity of the current working channel during data transmission can be directly obtained through an interference degree list stored in the terminal, a directional coupler for detecting the interference degree can also be added to the first radio frequency circuit, and the interference degree is detected through the directional coupler.
And 1013, if the interference degree is greater than a first preset value, determining that the interference information meets the first preset condition.
If it is determined that the read-write operation of the memory card interferes with the reception of the first signal, the first radio frequency circuit is controlled to be connected to a second antenna of a second radio frequency circuit when the first signal is received, the first radio frequency circuit needs to be electrically connected with the second radio frequency circuit, and a connection wire brings loss, so that the first preset value is set according to the loss value of the connection wire, the first preset value is not less than the loss value of the connection wire, and optionally, the first preset value is equal to the loss value.
If the interference degree is greater than the first preset value, the interference information meets the first preset condition, and the interference degree of the read-write operation of the memory card on the receiving sensitivity of the current working channel is considered to be greater, so that the switching of the connecting antenna is required to be performed when the first signal is received; if the interference degree is smaller than the first preset value, the interference information does not meet the first preset condition, the interference degree of the read-write operation of the memory card on the receiving sensitivity of the current working channel is considered to be small, and the switching of the connecting antenna can not be carried out.
Further, the step 1012 may include, but is not limited to, being implemented in the following manner:
the first method is as follows: determining the interference degree of the read-write operation of the memory card on the receiving sensitivity of the working channel according to the interference degree data; the interference degree data is stored in the electronic device, and when the memory card performs read-write operation, the memory card performs read-write operation on the data of the interference degree of the receiving sensitivity of the working channel of the first radio frequency circuit.
In this embodiment, the interference degree data may be obtained by testing with a test or a detection instrument, and the interference degree data may be stored in an electronic device in a form of a list, as shown in fig. 3, taking 10 working channels of the first radio frequency circuit as an example, fig. 3 shows a degree of interference on the receiving sensitivity of each channel when the first radio frequency circuit uses the first antenna to receive a signal; and a degree of interference with reception sensitivity of each channel when the first radio frequency circuit receives a signal using the second antenna of the second radio frequency circuit. The electronic device may determine, according to the interference degree data, an influence of data transmission of the memory card on receiving sensitivity when the current working channel of the first radio frequency circuit is receiving a signal, and control the first radio frequency circuit to receive the signal through a second antenna connected to the second radio frequency circuit when the interference degree is greater than a loss value caused by a connection wire between the first radio frequency circuit and the second radio frequency circuit.
The second method comprises the following steps: a directional coupler is disposed on the first radio frequency circuit.
The first radio frequency circuit comprises a directional coupler; and detecting the interference degree of the read-write operation of the storage card on the receiving sensitivity of the working channel through the directional coupler.
After the electronic equipment acquires the interference degree data of the read-write operation of the memory card on the receiving sensitivity of the current working channel of the first radio frequency circuit through the directional coupler, whether the interference degree data is larger than a loss value brought by a connecting wire of the first radio frequency circuit and the second radio frequency circuit or not is judged, and when the interference degree is larger than the loss value brought by the connecting wire, the first radio frequency circuit is controlled to receive signals through a second antenna connected with the second radio frequency circuit.
The following describes a specific implementation procedure of controlling the first rf circuit to connect to a second antenna of a second rf circuit when receiving the first signal and to connect to the first antenna when transmitting the first signal, in a case where it is determined that the read/write operation of the memory card interferes with the reception of the first signal.
As shown in fig. 4, a schematic layout diagram of an antenna and a memory card inside an electronic device is shown, and taking the first radio frequency circuit as a radio frequency circuit of a wireless network and the second radio frequency circuit as a main radio frequency circuit as an example, the electronic device includes: a battery 41 and a Printed Circuit Board (PCB) 42, on which a wireless rf Circuit module 43 and a main rf Circuit module 44 are disposed, wherein the wireless rf Circuit module 43 receives and transmits signals through a first antenna, and the main rf Circuit module receives and transmits signals through a second antenna, and a distance between the first antenna and the memory card 45 is smaller than a distance between the second antenna and the memory card 45. When the wireless network works, the frequency range of a received signal of the wireless network is 2402-2482 MHz, when the wireless network downloads data resources (such as movies and clients) to a memory card, or the wireless network is on line, the downloaded data resources are transmitted to the memory card, the memory card has read-write operation, and as the frequency of a data signal line is 50MHz when the memory card works, and the frequency range of the received signal of a first antenna of the wireless network contains a frequency doubling point of the frequency when the data of the memory card is transmitted, the data transmission of the memory card may influence the signal reception of a radio frequency circuit of the wireless network.
Similarly, if the second antenna of the main rf circuit is close to the memory card, when the LTE network is used for working and the working frequency point of the second antenna for receiving signals is at the frequency multiplication of 50MHz, when the LTE network downloads data resources to the memory card or the LTE network is on line and the downloaded data resources are transmitted to the memory card, the memory card has read-write operation, and since the frequency of the data signal line during the working of the memory card is 50MHz, the frequency range of the received signals of the second antenna of the LTE network includes the frequency multiplication point of the frequency during the data transmission of the memory card, the data transmission of the memory card may affect the signal reception of the main rf circuit.
It should be noted that fig. 4 is only an example of the layout of the antenna and the memory card inside the electronic device, and the positions of the antenna and the memory card are set according to the actual design of the terminal.
Taking the first radio frequency circuit as a radio frequency circuit of a wireless network and the second radio frequency circuit as a main radio frequency circuit as an example, when determining the interference degree of the read-write operation of the memory card on the receiving sensitivity of the current working channel according to interference degree data stored in the electronic device, the circuit structures of the first radio frequency circuit and the second radio frequency circuit include, but are not limited to, the following two forms:
