The outer weather prognosis electronic clock of wireless indoor
[technical field]
The utility model relates to a kind of electronic clock, and particularly a kind of temperature and humidity to indoor and outdoors has the electronic clock of monitoring function.
[background technology]
Occurred a kind of electronic clock now on the market, it, and is presented at monitoring result on the LCD display of electronic clock with monitoring function indoor temperature and humidity and outdoor temperature and humidity.Wherein, comparatively simple to indoor temperature and humidity monitoring, only need electronic clock correct position a Temperature Humidity Sensor is set, again by associated circuit components with sensor sensing to data presentation on LCD display, get final product, but monitoring for outdoor temperature humidity, because of need at the outdoor Temperature Humidity Sensor of establishing, need again data presentation is being placed on the indoor electronic clock LCD display, therefore relatively more difficult, present way is to utilize the electric wire associated circuit components that outdoor Temperature Humidity Sensor and indoor electric secondary clock is interior to be connected, because of the limited length of electric wire, make indoor electronic clock arbitrarily to put, use inconvenience; In addition, electric wire connects indoor and outdoors, needs boring on the wall or from cablings such as windows, causes the problem that wall destroys or window can't be closed tight; And this connected mode also causes the preparation of monitoring not high, and is stable inadequately.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of wireless indoor outer weather prognosis electronic clock, adopts wireless mode, easily monitors outdoor humiture, and is accurately convenient.
The utility model is achieved in that the outer weather prognosis electronic clock of a kind of wireless indoor, comprise that one is located at indoor electronic clock body and and is located at outdoor Temperature Humidity Sensor, it is characterized in that: described electronic clock also comprises an off-premises station, described Temperature Humidity Sensor is located on this off-premises station, also be provided with a transmitter and the described Temperature Humidity Sensor that links to each other on this off-premises station, then be provided with a receiver on the electronic clock body.
Wherein, described transmitter and receiver are frequency-modulated transmitter and fremodyne, all comprise three frequency ranges.
Wherein, also connect a receiving antenna on the described receiver.
Wherein, described off-premises station also comprises a LCD display, and the described Temperature Humidity Sensor of this LCD display is connected.This off-premises station also comprises a support, and this off-premises station is fixed on the outdoor wall by described support.
The utility model adopts above-mentioned structure, structure is in the past compared has following advantage: at the outdoor off-premises station that is provided with, and Temperature Humidity Sensor and transmitter be located on the off-premises station, Temperature Humidity Sensor can will pass through transmitter to the Monitoring Data of outdoor humiture, when the receiver on the electronic clock body is received data, related content can be shown on LCD display, make things convenient for the user to check.Because of using the cooperation of transmitter and receiver, the direct connection of saving electric wire need not to hole on the wall or from cablings such as windows, electronic clock can arbitrarily be put, and is flexible and convenient to use, moreover the accuracy height of frequency-modulated transmitter and fremodyne, transmits more stable.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the principle schematic of the outer weather prognosis electronic clock of the utility model wireless indoor.
Fig. 2 is the Facad structure synoptic diagram of the utility model electronic clock body.
Fig. 3 a and Fig. 3 b are respectively the front and the reverse side structural representations of the utility model off-premises station.
[embodiment]
See also illustrated in figures 1 and 2, the outer weather prognosis electronic clock of the utility model wireless indoor, comprise that one is located at indoor electronic clock body 1 and and is located at outdoor off-premises station 2, this off-premises station 2 is provided with a transmitter 21 and a Temperature Humidity Sensor 22, and this transmitter 21 links to each other with described Temperature Humidity Sensor 22 by the circuit component 23 of an off-premises station 2 inside; Then be provided with a LCD display 11 on the electronic clock body 1, and one with the receiver 12 of transmitter 21 corresponding matching, described receiver 12 is connected with described LCD display 11 by the interlock circuit 13 that is located at electronic clock body 1 inside, also connect a receiving antenna 14 on this receiver 12, this receiving antenna 14 also is located on the described electronic clock body 1.
Described transmitter 21 and receiver 12 are frequency-modulated transmitter and fremodyne, all comprise three frequency ranges.During use, arranged the reception frequency range of receiver 12 on the electronic clock body 1 earlier, transmitter 21 frequency ranges on the off-premises station 2 have been set again, made identical the getting final product of reception frequency range of transmit frequency band and described receiver 12 on the transmitter 21.The useful effect radius distance of the transmitter of common this electronic clock and receiver is 10 meters, after fixing off-premises station 2, can arbitrarily place electronic clock body 1 in radius distance is 10 meters scope, and is flexible.
Shown in Fig. 2 a and Fig. 2 b, the front of off-premises station 2 is provided with a LCD display 24, this LCD display 24 is connected with described Temperature Humidity Sensor 22 by circuit component 23, makes things convenient for the user directly to read the related content that Temperature Humidity Sensor 22 monitors on off-premises station 2.In addition, off-premises station 2 is fixing for convenience, described outdoor 2 machines can be equipped with a support 25, is drilled with Luo hole 252 on the support 25, this off-premises station 2 can be fixed on the outdoor wall by screw.
The outer weather prognosis electronic clock of this wireless indoor also has the weather prognosis function, electronic clock body 1 can calculate the air pressure on the same day according to the temperature and humidity that Temperature Humidity Sensor 22 monitors, to judge the weather condition in following several days, carry out weather prognosis, this weather prognosis is the result also show on the LCD display on the electronic clock body 1 11
In sum, the utility model is divided into electronic clock body and off-premises station two parts with electronic clock, the Monitoring Data of receiver by frequency modulation and transmitter transmission Temperature Humidity Sensor, when the receiver on the electronic clock body is received data, related content can be shown on LCD display, make things convenient for the user to check.Because of using the cooperation of transmitter and receiver, the direct connection of saving electric wire need not to hole on the wall or from cablings such as windows, electronic clock can arbitrarily be put, and is flexible and convenient to use, moreover the accuracy height of frequency-modulated transmitter and fremodyne, transmits more stable.
