The utility model adopts technique scheme, has following beneficial effect: realized the signaling distant control function, measured the display environment temperature.

Description of drawings

But the module map of the temperature measurement controller that Fig. 1 relates to for the utility model.

Fig. 2 is the circuit diagram of one-chip computer module.

Fig. 3 is the circuit diagram of temperature measurement circuit.

Embodiment

Be elaborated below in conjunction with the technological scheme of accompanying drawing to invention:

As shown in Figure 1, but the fan remote controller of thermometric comprises signaling circuit, key-press matrix, thermistor and the LCD display that is connected with one-chip computer module.

The system master one-chip computer module selects for use Taiwan to close 8 MCU HT46R64 that Thailand (Holtek) company produces, in build 32768Hz RTC crystal oscillation circuit and LCD drive circuit.The PWM end is exported infrared carrier wave simultaneously.Infrared carrier frequency is 38KHz and carrier wave EDM Generator of Adjustable Duty Ratio.

Build 10 ADC in the 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 is 4 at most, and the SEG port is 32 at most.

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.Time lag adjustment (10 seconds-60 seconds, stepping is 5 seconds) can be according to circumstances carried out in thermometry.Temporal information can be adjusted through button.

Emission conventional fan remote control mode behind the button.Lcd screen shows the signaling sign simultaneously, and the user is just at signaling in prompting.

As shown in Figure 2, the 4MHz crystal oscillation circuit provides system's operation master clock.The 32768Hz crystal oscillator provides RTC clock.The RESET of HT46R64 is the low level resetting pin, can directly connect high level.The built-in LCD drive circuit of system need not external multiplication of voltage electric capacity.

Key-press matrix is made up of 64 buttons, and 64 buttons can freely define signaling type and data, and are user-friendly.As shown in Figure 3,502ET is a thermistor, is used for thermometry.
