Background technology
In departments such as industrial and agricultural production, meteorology, environmental protection, national defence, scientific researches, often need measure and control environment temperature and humidity.It is vital especially for industries such as bio-pharmaceuticals, food processing, papermaking accurately to measure humiture.And traditional humiture detection method not only consumes a large amount of human and material resources but also usable range is little, and efficient is very low, can not satisfy the needs of science and technology and socio-economic development.
In addition, traditional Hygrothermograph all is to need the people for reading the humiture value, or the humiture of mercury pillar reads mode, or digital display mode.And its scale spacing of the Hygrothermograph of mercury pillar is too little, reads inconvenience, though the Hygrothermograph of digital display type has overcome this shortcoming, reads the humiture value and still have very big difficulty when the more weak people of eyesight uses.
Summary of the invention
The technical problems to be solved in the utility model is: Hygrothermograph usable range of the prior art is little, efficient is low and very inconvenient when using than weak person for eyesight.
In order to solve the problems of the technologies described above, the utility model provides a kind of Hygrothermograph of remote-controlled voice broadcast, it is characterized in that: comprising:
Power supply unit: be used to Hygrothermograph to provide work needed electric energy;
Humiture monitoring means: comprise humiture one body sensor, be used for described temperature and humidity is converted to digital signal;
Microprocessor unit: with the digital signal processing of described humiture monitoring means transmission is voice signal and vision signal;
Video is reported the unit: be connected with described microprocessor unit, show described microprocessor unit processed video signal;
Voice broadcast unit: be connected with described microprocessor unit, play the voice signal after described microprocessor unit is handled;
Signal receiving unit: be connected with described microprocessor unit, be used for receiving from user's voice playing request signal;
Also comprise signal transmitting unit: comprise telepilot, be used to utilize telepilot to send the speech play request signal to signal receiving unit, described signal receiving unit transfers to described microprocessor unit with the request of speech play, and described microprocessor unit is controlled described voice broadcast unit and reported voice signal.
What described telepilot sent is infrared signal.
Described signal receiving unit is an infrared signal receiver.
The voice signal that storage records in advance in the described data memory module.
Described video is reported the unit and is adopted LCD display.
Described voice broadcast unit adopts the sounding loudspeaker.
The beneficial effects of the utility model are:
(1) Hygrothermograph in the utility model is simple in structure, easy to use, video is reported real-time displays temperature value in unit and humidity value, and as long as the user needs, utilize telepilot to send the request speech play and just can hear voice broadcast temperature value and humidity value immediately, have higher efficient.
(2) the utility model is provided with the voice broadcast unit, therefore after Hygrothermograph measures temperature and humidity, microprocessor unit is asked voice signal and vision signal with temperature value and humidity value conversion, vision signal shows by LCD display, for convenience more user can utilize telepilot to send the voice broadcast request when the relatively poor user of eyesight uses, temperature value and humidity value just can be play in described voice broadcast unit, make the user obtain current temperature value and humidity value in intuitive and convenient ground more.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, according to specific embodiment of the utility model also in conjunction with the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is a system chart described in the utility model.
Embodiment
As shown in Figure 1, the utility model discloses a kind of Hygrothermograph of remote-controlled voice broadcast, comprising:
Power supply unit: be used to Hygrothermograph to provide work needed electric energy, power supply voltage range is at 3.3v-5.5v.
Humiture monitoring means: comprise humiture one body sensor, be used for described temperature and humidity is converted to digital signal; Described humiture one body sensor adopts the digital hygro sensor DHT21 of Guangzhou Ao Song Electronics Co., Ltd..DHT21 is a humiture compound sensor of calibrating digital signal output that contains.Sensor comprises the wet element of a resistance-type sense and a NTC temperature element.DHT21 hygrometric scope 0-100%RH, precision ± 3%RH, temperature-measuring range-40-100 ℃, precision ± 1 ℃.3.3-5.5V power supply.Adopt the unibus data layout, the MCU sequential operation is convenient.About a communication time 4ms, data are divided fraction part and integral part.Once complete data transmission is 40bit, and a high position goes out earlier.Data layout: 8bit, humidity integer data+8bit, the little logarithmic data+8bit of humidity, temperature integer data+8bit, the little logarithmic data of temperature+8bit verification and.
Microprocessor unit: with the digital signal processing of described humiture monitoring means transmission is voice signal and vision signal;
Video is reported the unit: be connected with described microprocessor unit, show described microprocessor unit processed video signal; Described video is reported the unit and is adopted LCD display, preferably, adopts LCD display 1602, divides two row to show Current Temperatures and humidity value.
Voice broadcast unit: be connected with described microprocessor unit, play the voice signal after described microprocessor unit is handled; Described voice broadcast unit adopts the sounding loudspeaker.Described voice broadcast unit is preferably the ISD1810 speech chip, and through specific recording, the voice signal that storage records in advance in the described data memory module.So only needing a microprocessor unit to provide needs to play the address of sound and the low level of PLAYL pin, described sounding loudspeaker just can playback.When playback, these voice are arranged in the system: " now temperature be ", " humidity is now ", 0 ~ 9, " ten ", " degree ", according to the calculation in a second of per three word playing times, playing time has three kinds of 2S, 1S, 0.5S.
Signal receiving unit: be connected with described microprocessor unit, be used for receiving from user's voice playing request signal; Described signal receiving unit adopts infrared signal to receive, and preferably adopts the integrated reception head of infrared ray of SHARP company, model GP1UXC41QS.The integrated reception head of infrared ray is 3 pin package, and wherein signal pins directly connects the external counting pin of microprocessor unit.
Also comprise signal transmitting unit: comprise telepilot, can adopt any TV remote controller, what send is infrared signal, utilize telepilot to send the speech play request signal to signal receiving unit, described signal receiving unit is an infrared signal receiver, described signal receiving unit transfers to described microprocessor unit with the request of speech play, and described microprocessor unit is controlled described voice broadcast unit and reported voice signal.
The temperature humidity value is reported and is at first play voice " temperature is now ", plays ten sounds to individual position of temperature value then, and what play at last is " degree ".Then play voice " humidity is now ", play ten sounds to individual position of humidity value then, that play at last is " RH ".
Though the utility model elaborates it by embodiment; but; those skilled in the art should be understood that; the any form of being made on this basis that does not exceed the claim protection domain and the variation of details all belong to the claimed scope of the utility model.
