Detailed Description
In order to provide an effective implementation scheme, the following embodiments are provided, and the embodiments of the present invention are described below with reference to the accompanying drawings.
The invention firstly provides a data card control method, which comprises the following steps as shown in figure 1:

Since power is the product of voltage and current, a voltage and current that change simultaneously by the same amount will cause a greater change in power level. Therefore, the data card control method can improve the control precision and the control accuracy.
In a specific embodiment, the measurement object refers to a data card, and when it is detected that output power at two ends of the data card changes, the position of the data card changes, and the output power values at two ends of the data card at the rotating position are obtained according to the current rotating position of the data card.
In a specific embodiment, the measurement object may also refer to a resistor connected in parallel and a resistor connected in series with the data card. When the output power of the two ends of the parallel resistor and the series resistor is detected to change, the position of the data card is changed, and the output power values of the two ends of the parallel resistor and the series resistor at the rotating position are obtained according to the current rotating position of the data card.
With the rapid development of 4G technology, 4G data services will become the leading factor of data transmission in wireless communication. Users are also confronted with an environment in which more and more heterogeneous networks coexist while using mobile communication services. When 2G, 3G and 4G networks exist simultaneously, the data card automatically switches the networks generally according to the network signal intensity. In the place where several networks coexist and the network signal strength appears critical value and the two networks have equal strength, the phenomena of repeated switching, network disconnection, reconnection and the like of the two networks may appear, which will bring extra power consumption of the data card and influence the user experience.
In view of this, in some embodiments of the invention,
the network connection state includes: connect one of at least two different networks, be in an automatic network selection state, or disconnect from the network.
Specifically, the at least two different networks include a 2G network, a 3G network, and a 4G network. More specifically, the at least two different networks include a GSM network, an EDGE network, a WCDMA network, an LTE network, and the like.
The preset power reference range may include six different ranges, which are a first setting range, a second setting range, a third setting range, a fourth setting range, a fifth setting range, and a sixth setting range, respectively.
The preset corresponding relationship between the set range and the network connection state includes:
the first set range corresponds to a disconnection of the network connection;
the second setting range corresponds to a dial-up connection network;

the fifth setting range corresponds to a connection 4G network;
the sixth setting range corresponds to an automatic network selection state;
the first setting range and the second setting range are not overlapped; the second setting range includes a third setting range, a fourth setting range, a fifth setting range and a sixth setting range.
Specifically, the method comprises the following steps: when the comparison result indicates that the power value is changed from a non-first set range to a first set range, controlling the data card to disconnect the network connection;
when the comparison result indicates that the power value is changed from a non-second set range to a second set range, controlling the data card to dial up a connection network;

When the output voltage and the current value of the data card are changed simultaneously, the power value can be changed to a greater extent than the output voltage or the output current, so that the adjustment sensitivity of the data card is improved, a plurality of setting ranges can exist in the adjustable range of the data card, and the number of adjustable states of the data card is increased. That is, when the sensitivity of the data card is low, it is only appropriate to set two network connection states of dial-up connection network and disconnection network connection; when the sensitivity of the data card is improved, the data card can be further controlled to be connected with different networks, automatically select the network, disconnect the network connection and the like.
