Abstract
The utility model relates to a remote controller for an air conditioning system, which comprises a single chip computer, a liquid crystal display, an operation keyboard, a power amplifier and an infrared emitter, an indoor temperature sensor and a battery voltage detecting circuit. The single chip computer, the temperature sensor and a divider resistance constitute an indoor temperature measurement circuit. The battery voltage detecting circuit comprises the single-chip computer, a voltage stabilizing diode and the divider resistance. The remote controller of the utility model regularly sends room temperature information to the indoor, which avoids unnecessary energy loss. The remote controller adopts the method of detecting the battery voltage to detect the electric quantity and reminds the user through the liquid crystal display, so as to ensure the normal operation of the remote controller and the air conditioning system.
Description
The utility model relates to a kind of air-conditioning system remote controller, belongs to technical field of automatic control.
In common air-conditioning system, all be the temperature that the temperature that detected with return air sensor is represented the room, because return air temperature greater than indoor temperature, is used the return air temperature stands for room temperature, not only can make room temperature be lower than the setting room temperature, and can make air-conditioning system consume more electric energy.In addition, along with the normal use of remote controller, the electric weight in the battery can reduce gradually, and it is more and more lower to show as cell voltage, shortens, receives insensitive or misoperation when battery electric quantity reduces to deficiency so that remote control distance can occur during the single-chip microcomputer operate as normal.This moment, the remote controller outward appearance showed normally, but can not normally use, should more renew battery, but general remote controller can't the reminding user to replace battery under this state.
The purpose of this utility model is a kind of air-conditioning system remote controller of design, temperature sensor and battery voltage detection circuit are set on remote controller, making the room temperature of air-conditioning system control is indoor air temperature, avoid unnecessary energy loss, in time detect cell voltage, and remind the user by liquid crystal display.
The air-conditioning system remote controller of the utility model design, comprise single-chip microcomputer IC1, LCD, operation keyboard, power amplifier and infrared emission circuit, wherein LCD and IC1 chip pin 1～12,35～44 directly link to each other, and are directly driven by the IC1 internal circuit; Described operation keyboard includes K1～K17 totally 17 buttons, and IC1 is coupled by pin 21～27 and 17, judges button by scan mode; Described power amplifier and radiating circuit are made up of triode P401, resistance R 418, R408, R409 and infraluminescence pipe D403, D404, transmit and are controlled by pin 18 by IC1; Described indoor temperature transmitter part is made up of thermistor TH401 and resistance R 403, and the variation of resistance value is passed on the pin 13 of IC1; Battery voltage detection circuit is made up of benchmark source of stable pressure ZD401 and resistance R 410, and the variation of cell voltage is passed on the IC1 pin 15.
The utility model is provided with temperature sensor in the remote controller leading edge, and remote controller so the room temperature that air-conditioning system is controlled is an indoor air temperature, has been avoided unnecessary energy loss regularly to the indoor room temperature information of sending simultaneously.This remote controller adopts and detects cell voltage method detection electric weight, and reminds the user by liquid crystal display, to guarantee the operate as normal of remote controller and air-conditioning system.
Description of drawings:
Fig. 1 is a circuit block diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Fig. 3 is the temperature measurement circuit figure in the remote controller.
Fig. 4 is the battery voltage detection circuit figure in the remote controller.
Below in conjunction with accompanying drawing, introduce content of the present utility model in detail.
As shown in Figure 1, the air-conditioning system remote controller of the utility model design comprises single-chip microcomputer IC1, LCD, operation keyboard, power amplifier and infrared emission, indoor temperature transmitter and battery voltage detection circuit.Single-chip microcomputer IC1, temperature sensor TH401, divider resistance R401 form indoor temperature measurement circuit, and battery voltage detection circuit comprises single-chip microcomputer IC1, voltage stabilizing didoe Z and divider resistance R403.
The circuit diagram of remote controller as shown in Figure 2, the temperature measurement circuit of remote controller as shown in Figure 3, by single-chip microcomputer IC1, temperature sensor TH401 and divider resistance R403 form.The A point meets V+ by transducer TH401, meets GND and joins with the road A/D input port of single-chip microcomputer IC1 by R403.When room temperature changes, the resistance respective change of TH401, A point current potential changes thereupon, Chip Microcomputer A/D mouth sampling A point voltage VA, the liquid crystal by remote controller illustrates the respective compartments temperature.
The battery voltage detection circuit of remote controller as shown in Figure 4, the current potential constant (with V+ point for referencial use) that utilizes the stabilized voltage characteristic of voltage stabilizing didoe Z that A is ordered.The supply power voltage and the cell voltage of the corresponding single-chip microcomputer of the full scale of the A/D of single-chip microcomputer IC1.And the current potential that A is ordered is constant.When cell voltage changes, current potential A/ cell voltage ratio will be changed like this, and this ratio just is the result of A/D conversion, software can calculate cell voltage according to this result.
