Abstract

An interphone with an embedded global system for a mobile communications (GSM) module relates to the technical field of wireless communication. The interphone consists of a GSM wireless communication module, an interphone module and an interface module, wherein the GSM wireless communication module is connected with the interphone module, the interphone module is connected with the interface module, the GSM wireless communication module not only has the functions of calling, receiving and sending short messages and common managing, but also is added with a push-to-talk (PTT) telephone book and a PTT program, a PTT frequency processing program is installed in the interface module, and an interphone processing program is installed in the interphone module. The interphone not can call in real time without paying the mobile phone calling fee, but also can realize group talk without arranging the communication frequency; and moreover, the interphone does not need to be in an on state when not calling, so that the electric quantity consumption of the interphone is saved, noise disturbances are also avoided, and meanwhile, the conversation quality can also be ensured.

Description

The intercom of embedded gsm module

Technical field:

The present invention relates to wireless communication technology field, relate in particular to a kind of intercom of embedded gsm module.

Background technology:

Cellular communication systems evolve was rapid in recent years, the cellphone subscriber constantly increases, mobile phone chats has been universal phenomenon very, but always bringing many telephone expenses spendings to us unconsciously, although intercom can satisfy the demand of people's short-range communication and not produce any communication cost, but also there are some shortcomings: be in for a long time open state such as needs, and communicating pair need be appointed communication channel in advance, crucial is to carry out toll message, is exactly that the voice conversation quality also has problems in addition.

Summary of the invention:

The present invention is in order to overcome the existing weak point of background technology, a kind of intercom of embedded gsm module is proposed, can immediate communication and do not need to pay the cell phone call charge of great number, can also realize group call and not need to arrange in advance communication frequency, and need not to be in open state when not conversing, both saved the electric quantity consumption of intercom, avoided again noise jamming, do not need through GSM network in the whole communication process, greatly saved cost of the phone call, the quality of conversation also can be guaranteed simultaneously.

The technical scheme that the present invention solves the employing of background technology problem is as follows: it is comprised of gsm wireless communication module, intercom module and interface module, described gsm wireless communication module connects the intercom module, intercom module connection interface module, described gsm wireless communication module is except conversation, transmitting-receiving note and management function commonly used with common GSM mobile handset, PTT telephone directory and PTT program have also been added, interface module is equipped with PTT frequency processing program, and the intercom module is equipped with the intercom handling procedure.

Described PTT telephone directory is in charge of group and contacts list.

Described PTT program activates the intercom module, consults the employed frequency of conversation when needs use intercom function, the PTT program starts when user selection is initiated or receive conversation at running background.

Operation principle of the present invention:

When the user has the conversation demand, at first select the number of conversation object or input the other side gsm wireless communication module intercom, it is the GSM mobile handset number, simultaneously, gsm wireless communication module intercom obtains the voice frequency of a free time automatically in the frequency range that intercom can use, and utilize SMS to send to the other user by the GSM network this frequency values, after the other user's mobile phone is received SMS, judge it is the intercom activation request according to content, so activate the intercom module and the voice frequency of intercom adjusted to the value of appointment, so both call sides can utilize intercom directly to converse, if both sides' distance is not in the scope that intercom can cover, both sides can manual-lock intercom module, but still uses the function of GSM mobile handset to converse.

The present invention can realize following functions:

1, common mobile phone and intercom function.

2, the intercom module is in closed condition under normal circumstances, can pass through GSM note deexcitation the other side intercom, then uses the intercom chat.

3, from the request note that the PTT conversation is set up, extract the frequency values of intercom communication, thereby not needing to realize prior agreed frequency also can set up the intercom conversation.

If 4 a period of times were not used intercom conversation, autoshutdown intercom module then also can manual-lock.

The invention has the beneficial effects as follows:

1, it integrates the advantage of mobile phone and intercom, can be as mobile phone immediate communication and do not need to pay the cell phone call charge of great number, can as intercom, realize group call again and not need to arrange in advance communication frequency.

Both sides' intercom not need not to be in open state when 2, not conversing, both saved the electric quantity consumption of intercom, avoided again noise jamming, when having conversation to require, conversation each side only need activate the intercom module, do not need through GSM network in the whole communication process, greatly saved cost of the phone call, the quality of conversation also can be guaranteed simultaneously.

Description of drawings:

Fig. 1 is system configuration schematic diagram of the present invention;

Fig. 2 is workflow diagram of the present invention.

Embodiment:

The specific embodiment of the invention is as follows:

Be system configuration schematic diagram of the present invention with reference to Fig. 1, it is comprised of gsm wireless communication module, intercom module and interface module, described gsm wireless communication module connects the intercom module, intercom module connection interface module, described gsm wireless communication module is except conversation, transmitting-receiving note and management function commonly used with common GSM mobile handset, also added PTT telephone directory and PTT program, interface module is equipped with PTT frequency processing program, and the intercom module is equipped with the intercom handling procedure.

Be workflow diagram of the present invention with reference to Fig. 2:

1. the initiator selects the conversation object or directly inputs the other side's phone number at the PTT telephone directory, and object can be single or multiple contact persons and group.

The telephone number of each conversation object that 2. will select passes to the PTT program.

3. the PTT program produces the Random Communication frequency.

4. activate the intercom module and by interface module frequency is write intercom.

5. whether intercom to detect this frequency idle.

6. testing result is passed to mobile phone.

7. then repeat 3. above-mentioned-6. each step as this frequency is occupied, until the frequency free time that generates, the free time then sends by the GSM network to the recipient and sets up the request note and activate the intercom module.

8. whether the recipient selects to converse according to short message prompt after receiving and setting up the request note.

If 9. the recipient selects conversation, the PTT frequency processing Program extraction on the interface module goes out to set up the frequency values in the request note, activates the intercom module and frequency is write intercom, and both sides can utilize intercom to converse.
