At present, in a campus public telephone system of a traditional campus, in which an intelligent public telephone card with an SIM card is inserted, a call can be carried out after the intelligent public telephone card is inserted, but the traditional campus card public telephone only has a call function and does not have an encryption function for the SIM card, and the risk of telecommunication fraud caused by misunderstanders after the card is lost exists.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a campus public telephone and system that can encrypt lock card.

The utility model discloses a campus public telephone of lock card can encrypt, include: casing, main control unit, communication unit, display element and phone handle all with main control unit be connected, the casing on set up the plug-in card mouth that is used for inserting the intelligent public phone card of taking the SIM card in order to carry out the campus conversation, main control unit set up in the casing in, main control unit still connect be used for right SIM card on the intelligent public phone card advances the encryption unit of dynamic encryption, the SIM card after dynamic encryption, can only be in the campus public phone in by the matching use.

Further, the encryption unit may be turned on or off.

Further, the display unit may display an encryption status.

Furthermore, the encryption unit, the communication unit, the display unit and the phone handle are all connected with the main control unit through an I2C interface, an SPI interface or a mipi interface.

Further, the communication unit comprises at least one of a 4G module, a 5G module or a VOIP module.

The utility model discloses a campus public telephone system of lock card can encrypt, include: the campus public telephone comprises at least one communication mechanism and a service platform connected with the communication mechanism, wherein the communication mechanism is the campus public telephone.

The utility model provides a can encrypt campus public telephone and system of lock card has following beneficial effect:

be different from prior art, the campus public telephone of plug-in card formula can't encrypt the intelligent public telephone card of inserted area SIM card, leads to if the SIM card loses the back, probably carries out the telecommunications fraud by the user afterwards, the utility model discloses a campus public telephone and the system that can encrypt the lock card can encrypt the intelligent public telephone card of inserted area SIM card, and the SIM card only can be used in this type of campus public telephone matching after dynamic encryption, can't be used by the discernment on other terminals to avoid the telecommunications fraud.
