A first embodiment of the present invention, as shown in fig. 1, is a method for parameter invocation, which is applied to a mobile terminal having an NFC chip.
In this embodiment, the implementation environment of the method may include a card reader and a mobile terminal with an NFC function. Card readers are typically provided in barrier devices for scenes such as entrance, subway, bus, and toll ticket gates, which are used to control the entry and exit of pedestrians. The blocking device comprises a control chip, a card reader and a gate, wherein the card reader and the gate are connected with the control chip, and at least one NFC chip is arranged in the mobile terminal.
When the mobile terminal approaches the card reader, the mobile terminal is in a card simulation working mode, and in the working mode, the inside of the mobile terminal is equivalently configured with a simulation card adopting a Radio Frequency Identification (RFID) technology. The simulation card can replace the application scene of the entity card, and the entity card can be a market card, a bus card and the like. The coils in the card reader generate electromagnetic fields around, each group of radio frequency parameters loaded in the mobile terminal with the NFC chip corresponds to one card reader, and the electromagnetic fields emitted outwards by the card reader are used for activating the NFC chip in the mobile terminal which operates according to each group of radio frequency parameters. The card reader can read card identity information data from the NFC chip, sends the identity information data to the control chip, and judges whether identity authentication is effective or not, so that the blocking device is controlled to be opened.

The radio frequency parameters of the POS include a power supply voltage, a voltage phase, a voltage amplitude and a voltage threshold.
It should be noted that the voltage threshold value indicates that the NFC chip configured with the radio frequency parameter adjusts the adjustable resistor through the voltage adjustment module, so that the voltage output by the battery passes through the adjustable resistor, and then the adjusted voltage input to the voltage comparator tends to the threshold voltage of the near field communication unit. The state of a voltage at a certain time (or a certain position) can be represented by a value called voltage phase.
In this embodiment, the radio frequency parameters of the POS may further include a voltage static load value and a voltage dynamic load value, where the voltage static load value indicates a load value of a voltage under a condition that impedance is not changed; and the voltage dynamic load value represents a load value of a voltage under a condition that an impedance changes according to an input signal frequency of the circuit.
To sum up, the method for parameter calling provided by the application acquires the radio frequency parameter configuration table and the preset default parameters of the entrance guard from the cloud server. The radio frequency parameter configuration table may include radio frequency parameters of POS corresponding to public transportation sales terminals in different cities, different regions, or different countries.

After parameter information sent by a cloud server is acquired within a daily preset time period, a request signal for establishing near field communication sent by a card reader on a public transport POS machine is received, the request signal is a first control instruction, and the first control instruction is used for paying the cost of a target bus.

And responding to the second control instruction, calling preset door control default parameters and loading the door control default parameters into the NFC chip. The default parameters of the preset entrance guard can be subjected to data interaction with the entrance guard card readers of at least two entrance guard types, so that the entrance guard card readers of the at least two entrance guard types can contact the entrance guard.
