Technical field
The present invention relates to a kind of use STC chip microcontroller to the control of infrared ray transmitter and receiver and relay
System.
Background technology
Smart Home electrical apparatus control system requires to be capable of by infrared ray or the work of radio control household electric appliances
Make state.In order to improve the stability of product in design, we use STC single-chip microcomputer to complete to control part,
Launch infrared control relay by remote controller, thus indirectly go to control the state of each electrical equipment.Anti-theft journal
Alert part, we use pyroelectric sensor, the infrared letter of human body detected during the work of preset warning circuit
Corresponding actuation of an alarm is performed after number.
Summary of the invention
Native system is made up of PC main frame and single-chip microcomputer client two large divisions, and two parts are led to by RS232 agreement
News, it is achieved the function of real-time synchronization data.Single-chip microcomputer client has with the main one-tenth of lower part: serial communication, PS2
The control of Keyboard Control, infrared remote control, photoelectric sensing, pyroelectricity, temperature sensing, 12864 Liquid Crystal Modules shows,
Buzzer warning, 8 way switch control;PC host side owned man-machine communication module, user also can be at PC
End realizes the control of 8 way switch by keyboard and mouse;PC host side is responsible for receiving and processing from list simultaneously
The control data of sheet machine client and defence area data, realize single-chip microcomputer client and PC master by certain algorithm
The data syn-chronization of machine end;PC host side is also responsible for synchronizing system clock and the function of displays temperature data;PC end
The function distinguishing defence area He recording the up-to-date Defence areas alarm time is had when processing defence area data;Wherein realize in real time
Synchronize it is crucial that data exchange and interrupt processing.

Detailed description of the invention
Temperature sensor we use DS1820 one-wire digital thermometer, DS1820 digital thermometer with
The temperature value of the form reflection device of 9 bit digital quantity.
DS1820 is sent by one-wire interface or the information of reception, therefore central microprocessor and DS1820 it
Between only need a connecting line (plus ground wire).Power supply for read-write and temperature transition can be from data wire itself
Obtain, it is not necessary to external power source.
Because each DS1820 has a unique sheet serial number, many DS1820 can connect simultaneously
On a single bus,
Thus temperature sensor can be placed on many different places.This characteristic is in HVAC environmental Kuznets Curves, spy
Survey building, instrument or the temperature of machine and the aspect such as process monitoring and control is highly useful.
DS1820 relies on a single line port communication.Under single line purt condition, it is necessary to first set up ROM operation
Agreement, just can carry out memorizer and control operation.Therefore, first controller must provide following 5 ROM
One of operational order: 1) reading ROM, 2) coupling ROM, 3) Search ROM, 4) skip ROM, 5) report to the police
Search.The laser ROM portion of each device is operated by these orders, hangs with multiple on single bus
During device, individual devices can be distinguished, how many devices or assorted can have been indicated to bus control unit simultaneously
The device of model.After the complete ROM sequence of operation of successful execution, memorizer can be carried out and control operation,
Controller can provide 6 memorizeies and any bar controlled in operational order.
Article one, control operational order instruction DS1820 and complete a temperature survey.Measurement result is placed on DS1820
Buffer in, can be data read-out in buffer with the storage operation order of a reading buffer content.
Temperature alarming trigger TH and TL is respectively made up of an EEPROM byte.Use without to DS1820
Warning search command, these depositors can use as general purpose user memory.Can be with one
TH and TL is write by storage operation order, and the reading to these depositors needs to pass through buffer.
All data are all to be written and read in the preceding mode of least significant bit.The power supply that the design uses is predominantly
+5V.Ringing a bell in system in this intelligence, ours is AC buzzer, due to the driving of general I/O mouth
Limited in one's ability, at this, we have employed audion 9013 to drive buzzer, and matrix keyboard is also called determinant
Keyboard, it is as line, the keyboard that 4 I/O lines form as alignment with 4 I/O lines.At line and
On each cross point of alignment, a button is set.So in keyboard, the number of button is 4 × 4.This
Plant determinant keyboard structure and can be effectively improved the utilization rate of I/O mouth in Single Chip Microcomputer (SCM) system.
First from high four output low levels of P1 mouth, low four output high level, from low four readings of P1 mouth
Keyboard state.Again from low four output low levels of P1 mouth, high four output high level, from the height of P1 mouth
Four are read keyboard state.Twi-read result is combined and can be obtained by the feature coding of current button.
Make in aforementioned manners that we obtain the feature coding of 16 keys.
