Background technology
Repeater (Repeater) is a kind of device that connects network line, is usually used in the two-way forwarding work of physical signalling between two network nodes.Repeater is mainly finished the function of OSI physical layer, is responsible on the physical layer of two nodes step-by-step and transmits information, finishes the duplicating of signal, adjustment and enlarging function, prolongs the transmission range of network with this.There is following problem in existing wireless repeater: do not possess anti-lightning strike function, be struck by lightning more frequent season, the repeater of outdoor use very easily is struck by lightning and is damaged, and stability in use and reliability are relatively poor.Do not possess the temperature controlled function, particularly in the summer of weather sweltering heat, the repeater under sunlight directly shines is easy to burn because the internal circuit temperature is too high, and useful life is comparatively limited.
In addition, at present, the lightning protection component in repeater field has piezo-resistance, TVS Transient Voltage Suppressor, discharge tube and thermistor etc.General single piezo-resistance or the TVS of adopting of the equipment that the lightning protection class requirement is lower cooperates discharge tube to carry out the protection of differential mode common mode; Usually the lightning protection circuit that needs two-stage even more multistage number for the higher equipment of lightning protection grade.And the most of power of the TVS that is used for lightning Protection commonly used at present is all smaller, and powerful TVS price is all very expensive usually; Discharge tube has shortcomings such as the slow and residual voltage of discharge is big, is easy to lose efficacy or damaged than sensitivity or the less chip load of volume when using.
As shown in Figure 2, be secondary lightning prevention circuit commonly used at present.Though this method has been used the two-stage lightning protection circuit, because there is the bigger defective of residual voltage in piezo-resistance, its residual voltage can increase along with the increase of thunderbolt energy, is easy to load is caused damage, and lightning protection properties is unreliable, damages wireless repeater easily.
The utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of wireless repeater based on wireless self-networking of can be anti-lightning strike and having the thermostatic control function is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of wireless repeater based on wireless self-networking, it comprises processor, signal receiving unit, signal data copied cells, signal screening unit, signal adjustment unit, signal transmitting unit, anti-lightning strike surge unit, voltage regulation unit and temperature control unit, and signal receiving unit, signal data copied cells, signal screening unit, signal adjustment unit, signal amplification unit, signal transmitting unit, anti-lightning strike surge unit, voltage regulation unit are connected with processor respectively with temperature control unit; Signal adjustment unit comprises filter circuit, signal attenuation compensating circuit, signal error correction circuit and signal amplification circuit.

Further, anti-lightning strike surge unit also comprises electrochemical capacitor C, and the end of electrochemical capacitor C is connected with power output end is anodal, and the other end links to each other with the power output end negative pole, and cross-over connection is on the end of the second piezo-resistance MOV2.
Cross-over connection has soft-start circuit between the end of the second piezo-resistance MOV2 and the end of electrochemical capacitor C, and soft-start circuit is a metal-oxide-semiconductor.
The operation principle of anti-lightning strike surge unit is as follows:
The first pressure sensitive voltage MOV1 of power input mouth carries out the one-level protection, and through decoupling circuit (inductance L), the second piezo-resistance MOV2 does the secondary protection, and electrochemical capacitor C absorbs energy, protects as the third level.
When lightning strike signals enters; the second piezo-resistance MOV2 at first makes action; release current, the voltage of the first piezo-resistance MOV1 move after reaching starting resistor again, release energy; because the existence of third level electrochemical capacitor C; can suppress residual voltage, absorb energy, after this protection; the received thunderbolt energy lightning protection circuit more in the past of the load system of power output end has had very large reducing, and load can obtain more effective and reliable protection.Because the impulse current when electrochemical capacitor C starts is bigger, there is certain influence in the circuit of front, can reduce impulse current so before electrochemical capacitor C, increase a soft-start circuit, play the effect that better alleviation is struck by lightning.
The beneficial effects of the utility model are:
(1) at wireless repeater inner integrated anti-lightning strike surge unit, voltage regulation unit and temperature control unit, can effectively prevent thunderbolt, the internal circuit that also can be repeater provides stable operating voltage and working temperature, for each circuit element of forming control circuit provides stable operational environment, repeater is played the better protect effect, improved the adaptive capacity to environment and the useful life of repeater;
(2) on the basis of original two-stage piezo-resistance secondary lightning prevention circuit, electrochemical capacitor and soft-start circuit have been increased newly, can effectively absorb the thunderbolt energy, suppress the increase of residual voltage, reduce impulse current, play the anti-lightning strike effect of the third level, guaranteed the stability of repeater operation.
