Abstract
The utility model relates to a wireless signal stretcher, which comprises a housing and each function unit in the housing. The utility model is characterized in that the function unit comprises a wireless receiving unit used for receiving the wireless signal sent by an upper device, a signal processing unit which has the received signal, a wireless sending unit used for sending the output signal of the signal processing unit to a lower device and an electrical unit used for providing electrical source for each unit. The wireless signal stretcher of the utility model can receive the signal sent by the upper device and transmit the signal to the lower device, when the transmitting distance is relatively far or when the emitter and the receiver are respectively arranged in different floors in the same edifice, the utility model can also guarantee the signal sent by the emitter transmitted to the receiver accurately.
Description
Technical field
The utility model relates to the emission and the reception technique of wireless signal, more particularly, relates to and a kind ofly is used to receive signal that the previous stage device sent and it is forwarded to the wireless signal stretcher of back one stage arrangement.
Background technology
Along with the continuous development of modern science and technology, various transducers or detector are applied to household, market or office space more and more, reach various purposes such as automation, safe and energy-conservationization.The detected signal of various transducers or detector will send corresponding receiver to and respond, and for example passes the signal to receiver with the control lighting lamp, walks out-of-date electric light electrified light emitting as the people; Perhaps be used to control warning device, when the people swarms into surveillance zone, send alarm signal.In the existing like product, have plenty of detector and reception responsor are designed together; Also have plenty of detector and receiver are designed to isolating construction, and adopt wireless mode to transmit signal.Wherein the use of a kind of mode in back also more and more widely for example at a plurality of diverse location installation and measuring devices in same building, is installed in receiver other different receiving position then.But present like product is subjected to the restriction of national standard because of frequency and power aspect, under the situation such as far away when distance that needs transmit, that barrier is more, when for example detector is located at the different floor of same mansion respectively with receiver, may be because of the decay of signal, interference etc. former thereby cause the reception variation, thus problems such as missing receipts caused.
The utility model content
For overcoming the above-mentioned defective of products such as existing detection, control, warning, the utility model provides a kind of wireless signal stretcher, can receive signal that the previous stage device sent and it is forwarded to back one stage arrangement, guarantee that the signal that detector sent can be sent to receiver like clockwork.
The technical solution of the utility model is, construct a kind of wireless signal stretcher, form by shell and each inner functional unit thereof, in described functional unit, receive the wireless signal that is sent by its previous stage device by radio receiving unit, handle to the received signal by signal processing unit again, by wireless transmitting unit the output signal of described signal processing unit is transmitted into back one stage arrangement then, and provide power supply for above-mentioned each unit by power subsystem.
In wireless signal stretcher described in the utility model, described power subsystem comprises civil power ac input end, rectification circuit and voltage stabilizing circuit.
In wireless signal stretcher described in the utility model, described shell comprises fore shell and back cover, and described ac input end is an attaching plug that is stretched out, can directly be inserted the common power socket by described back cover.
Wireless signal stretcher of the present utility model, can receive signal that the previous stage device sent and it is forwarded to back one stage arrangement, when far away the or detector of the distance that transmits when needs is located at the different floor of same mansion respectively with receiver, can guarantee that also the signal that detector sends can be sent to receiver like clockwork.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram when adopting a wireless signal stretcher of the present utility model to carry out signal extension;
Fig. 2 is the schematic diagram when adopting two wireless signal stretchers to carry out signal extension;
Fig. 3 is the schematic appearance of the utility model wireless signal stretcher;
Fig. 4 is the circuit theory diagrams of the utility model wireless signal stretcher.
Embodiment
Be illustrated in figure 4 as the circuit diagram of the utility model wireless signal stretcher, as can be seen from the figure, its circuit comprises the radio receiving unit that is positioned at upper right quarter, the signal processing unit that is positioned at lower left quarter, the power subsystem that is positioned at the wireless transmitting unit of right lower quadrant and is positioned at upper left quarter.
Wherein, power subsystem is used to other each unit that power supply is provided, and as can be seen from Figure 3, comprises the civil power ac input end, the rectification circuit of being made up of D1-D4 and the voltage stabilizing circuit of being made up of electric crystal Zener diode and capacitor element.
The receiver module of radio receiving unit is used to receive the wireless signal that is sent by its previous stage device, and the high-frequency signal of the ASK (amplitude shift keying) that receives is converted to pulse signal, and then delivers to signal processing unit.
Signal processing unit IC2 is a monolithic MCU (the EM78P156ELP chip that can adopt the curved ELan company of platform to produce), after receiving the signal that radio receiving unit transmits, decipher judgement,, then temporarily store if signal is the code system signal that meets predetermined format, and determine whether the in addition code system signal of saving format, if no, then pass to wireless transmitting unit, simultaneously, the LED that is connected with IC2 is bright, with indication the signal emission is arranged.
Wireless transmitting unit adopts crystal oscillating circuit, and after receiving the useful signal that MCU transmits, crystal oscillation produces high-frequency signal, goes out by transmission antennas transmit, by stage arrangement reception thereafter.
The utility model wireless signal stretcher has fixing reception and tranmitting frequency, for example receive only and send the signal of 433.92MHz (can change its operating frequency by changing internal circuit as required), the signal of other frequency can not be received, that is to say, each stretcher only has progradation to the signal of a certain frequency, does not then have progradation for the signal of other frequency.
Be illustrated in figure 3 as the profile schematic diagram of the utility model wireless signal stretcher, as can be seen from the figure, comprise fore shell 1 and back cover 2, wherein the ac input end of power subsystem is an attaching plug 3 that is stretched out, can be inserted the common power socket by back cover 2.This structure makes signal extender of the present utility model can directly insert the Electricity supply socket, uses easily.In addition, on the surface of fore shell a transparent light guide sheet 4 is housed also, above-mentioned LED light is being equipped with in the lining.
The utility model wireless signal stretcher use-case as illustrated in fig. 1 and 2.In Fig. 1, when detecting between reflector and the receiver the far away or barrier of distance more for a long time, will detect the signal that reflector sends by a wireless signal stretcher and be sent to receiver.In Fig. 2, when detecting between reflector and the receiver the farther or barrier of distance more for a long time, can will detect the signal that reflector sends by two wireless signal stretcher A and B and be sent to receiver.The final signal that guarantees that detector sent can be sent to receiver like clockwork.
