Abstract
The utility model discloses a short message gateway. The short message gateway comprises a short message receiving module, a short message sending module, and a power module which is used to supply power to the short message receiving module and the short message sending module; and the power module is connected with an over temperature protection circuit. The advantages of the utility model are that: the over temperature protection function is realized so as to protect the power performance, and to prevent the high temperature from damaging the power supply.
Description
Technical field
The utility model relates to communication equipment field, relates in particular a kind of Short Message Service Gateway.
Background technology
Short Message Service Gateway full name is internet short message gateway, mainly for solving short message inter-communication between each network, each operator and the access problem of SP.It is the dynamic data switch providing for transmitting-receiving note.Cellphone subscriber increases, and short message service has become one of frequent business using of cellphone subscriber.Its Short Message Service Gateway is the visual plant of information interaction.Existing Short Message Service Gateway, power module is directly given note receiver module and SMS transmission module power supply, and still, because power module is always in running order, its heating excessively can make the performance of power module wreck or make it out of control.If power supply wrecks, will bring massive losses to Virtual network operator.

For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of Short Message Service Gateway, it comprises note receiver module, SMS transmission module and for note receiver module and SMS transmission module provide the power module of electric energy, on described power module, is connected with thermal-shutdown circuit.
Further technical scheme is:
As preferably, described thermal-shutdown circuit comprises diode D3, the anode of described diode D3 is connected to the ground by inductance, the negative electrode of described diode is connected to the ground by capacitor C 2, the anode of described diode D3 is connected to by resistance R 3 on the anode of diode D1, the negative electrode of described diode D1 is connected on the negative electrode of voltage stabilizing didoe D2, the negative electrode of described diode D1 is connected on thermistor R2, the other end of described thermistor R2 is connected to the ground by resistance R 4, between the anode of described diode D1 and the negative electrode of diode D2, be connected with resistance R 1, the anode of described diode D1 is connected to the ground by capacitor C 1.
Further, the capacitance of described capacitor C 1 and capacitor C 2 equates.
Compared with prior art, the beneficial effects of the utility model are:
The utility model connects thermal-shutdown circuit on the power module of Short Message Service Gateway, in the time of the excess Temperature of power module, power supply is protected, and avoids power source performance to be destroyed.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is theory diagram of the present utility model.
Fig. 2 is the theory diagram of thermal-shutdown circuit of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Execution mode of the present utility model includes but not limited to the following example.
[embodiment 1]
A kind of Short Message Service Gateway as shown in Figure 1, it comprises note receiver module, SMS transmission module and for note receiver module and SMS transmission module provide the power module of electric energy, on described power module, is connected with thermal-shutdown circuit.The utility model connects thermal-shutdown circuit on the power module of Short Message Service Gateway, in the time that the temperature of power module exceedes certain value, power supply is protected, and avoids power supply excess Temperature to damage power source performance.
[embodiment 2]
A kind of Short Message Service Gateway as shown in Figure 2, described thermal-shutdown circuit comprises diode D3, the anode of described diode D3 is connected to the ground by inductance, the negative electrode of described diode is connected to the ground by capacitor C 2, the anode of described diode D3 is connected to by resistance R 3 on the anode of diode D1, the negative electrode of described diode D1 is connected on the negative electrode of voltage stabilizing didoe D2, the negative electrode of described diode D1 is connected on thermistor R2, the other end of described thermistor R2 is connected to the ground by resistance R 4, between the anode of described diode D1 and the negative electrode of diode D2, be connected with resistance R 1, the anode of described diode D1 is connected to the ground by capacitor C 1.In the present embodiment, the negative electrode of diode D3 is connected on power supply.A thermistor R2 connects on diode D1; in the time that temperature raises; the resistance of thermistor R2 starts to decline; now, the voltage of the common port of resistance R 2 and resistance R 4 raises, when magnitude of voltage is elevated to after certain value; make not conducting of diode D2; make device simply latched, then restart, power supply is protected.Capacitor C 1 and capacitor C 2 absorb disturbing, the reliability of intensifier circuit.
In order further to improve the performance of circuit, described capacitor C 1 and the capacitance of capacitor C 2 equate.
Be as mentioned above embodiment of the present utility model.The utility model is not limited to above-mentioned execution mode, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection range of the present utility model.
