Further, the temperature measurement module of the TV remote controller of band temp sensing function of the present utility model adopts thermistor 502ET.
Beneficial effect:
The utility model has comparatively exact temperature measurement function when realizing the common TV remote-controller function.Simultaneously, system is with the frequency sleep awakening of 2Hz, promptly with the operation of higher system clock, reduced the power consumption of system to a great extent after waking up, significant prolongation the service time of battery.
Description of drawings:
Fig. 1 is the TV remote controller block diagram of band temp sensing function.
Specific embodiments:
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
As shown in Figure 1, the TV remote controller of band temp sensing function of the present utility model, comprise one-chip computer module, signaling circuit, key-press matrix, temperature measurement module and LCD display, wherein one-chip computer module is connected with signaling circuit, key-press matrix, temperature measurement module and LCD display respectively.
One-chip computer module: one-chip computer module comprises that main MCU, power-supplying circuit, oikocryst shake, RTC crystal oscillator and liquid crystal drive interface circuit.The system master one-chip computer module selects for use Taiwan to close 8 MCUHT46R64 that Thailand (Holtek) company produces, built-in 32768Hz RTC crystal oscillating circuit and LCD driving circuit.The PWM end is exported infrared carrier wave simultaneously.Infrared carrier frequency is 38KHz and carrier wave EDM Generator of Adjustable Duty Ratio.
Built-in 10 ADC of HT46R64, in conjunction with thermistor 502ET, the attainable temperature-measuring range of system is-10 ℃～+ 40 ℃, and guarantees 0.5 ℃ resolution.
The COM port of LCD display mostly is 4 most, and the SEG port mostly is 32 most.
Temperature measurement module: temperature measurement module is thermistor 502ET.Adopt resistor voltage divider circuit to realize the converted measurement of temperature to voltage.
The key-press matrix module: the key-press matrix module is provided with 8 input ports and 8 delivery outlets of MCU and realizes the 8*8 keyboard.
Signaling circuit (infrared transmission module): infrared transmission module utilizes the PWM0 mouth of MCU to produce infrared waveform, drives the infraluminescence pipe, sends remote signal.After powering on, main control MCU is carried out initialization to system.LCD display system initial time information.Carry out thermometric simultaneously.Temperature data is presented at temperature on the lcd screen after main control MCU is handled.After this, system also constantly refreshes real-time clock with frequency operation between sleeping, waking up of 2Hz.Temperature survey can according to circumstances be carried out the time interval and adjust (10 seconds-60 seconds, stepping is 5 seconds).Temporal information can be adjusted by button.
Emission common TV remote control mode behind the button.Lcd screen shows the signaling sign simultaneously, and the user is just at signaling in prompting.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
