The analogy method of described each environment parameter to be measured of the present invention, as shown in Figure 1, it mainly comprises following step to described processor:
The first step: described processor brings into operation, and accepts the input of various control signals from described a plurality of switches.
Second step: described processor is judged the classification of this control signal, if this control signal is a switching signal, is water logging interface or the output of antitheft interface from port directly with this switching signal then; If this control signal is a smoke signal, then from the square-wave signal of port output 1KHz, this square-wave signal can be produced by a square wave maker, also can be generated by the counter of described processor; If this control signal is a simulating signal, then described processor reads in from the set pairing humidity value of aanalogvoltage of described second switch 2, carry out the processing of data, to handle the back data then and give described D/A converter, the aanalogvoltage after this D/A converter will be changed is exported from described humidity interface; If described control signal is a temperature signal, then described processor reads in the temperature value that described the 3rd switch is provided with, and the line data of going forward side by side is handled, then from described temperature interface output.
The 3rd step: after the operation of intact each the control signal correspondence of described processor processing, return and continue to read in next control signal.
The processing of the software section of the inventive method as shown in Figure 3 and Figure 4.Fig. 3 is described processor main program flow chart, mainly produces the program circuit of analog temperature signal with analog D S18S20.
The step of its execution is:
1, register in the described processor initialization sheet.Open the interrupt function of INT0, INT1, open the serial ports interrupt function; Interrupt priority level is set; It is 0 working method that serial ports is set; INT0, INT1 are set are the negative edge triggering; It is the baud rate working method that counter T2 is set; And the frequency of this baud rate is set.
2, described temperature control signals connects the common I/O mouth and the INT1 mouth of described processor simultaneously.
3, after described INT1 mouth receives negative edge,, jump to the program segment that calculates low level length and carry out by the redirect that in the INT1 interruption subroutine, is provided with; If low level length greater than a predetermined amount of time, as 480us, then sends sensor signal on the throne.Before sending sensor signal on the throne, close described INT1 interrupt function, open this INT1 interrupt function after sending sensor signal on the throne.
4, receive the temperature reading command of described equipment under test, if receive, then the numerical value with port P0 reads in described processor, exports by the pin of analog temperature signal after treatment.Because the analog temperature signal is 16 bit value, low eight bit representation temperature values, high eight-bit is represented the positive and negative of temperature; And actually, because can satisfy the test needs with 7 bit representation temperature values in the actual test, therefore can be in code switch low 7 be used to be provided with the temperature absolute value, and most significant digit is used to be provided with the positive and negative of temperature.
5, described processor sends the low byte of temperature earlier, sends upper byte again.
6, read temperature instruction and send temperature signal and all follow the 1-wire agreement.Detect low level arrival by INT1 when reading the instruction of described temperature, i.e. the opening flag of each data; And send the interrupt function of closing INT1 before the described temperature signal, open again after sending.
Be the described INT0 interruption subroutine process flow diagram in the inventive method as shown in Figure 4, promptly realize the process flow diagram of humidity function.
The data that humidity sensor LTC1655 receives are 16 serial data, and code switch can only be provided with 8 bit data, to enough as the precision of 5V aanalogvoltage in the test with 8 bit data, therefore 8 bit data that can be provided with code switch are as a high position, and it is 0 that low level replenishes.Need send this serial data at twice to described D/A converter.The removing of serial ports sign F0 is finished in the serial ports interruption subroutine, after having opened the serial ports interrupt function, after serial ports sends data, will jump into the serial ports interruption subroutine automatically, F0 changes to this serial ports sign.Its concrete execution in step is as follows:
It is that the look-at-me of described first switch 1 enters interruption subroutine that a, described processor receive touch-switch;
B, described processor read in the set 8bit numerical value of described second switch 2 from port P2;
C, described processor are provided with the chip selection signal of described D/A converter for effective;
D, described processor are provided with its serial ports and send sign F0=1;
E, described processor send upper byte from this serial ports;
F, wait F0 become 0;
G, when F0=0, described processor sends low byte from described serial ports, this low byte is 0;
H, wait F0 are 0
I, described processor are removed the chip selection signal of this D/A converter.
It as above is the method step of each environment parameter of simulation of the inventive method, the inventive method is according to the different characteristics of varying environment amount, ambient humidity, temperature, smog, water logging and varying environment amount such as antitheft have correspondingly effectively been simulated, only need apparatus of the present invention are connected described equipment under test by line, then need not time-consuming operations of taking a lot of work such as actual experiment, simply, expense is low.

B343) after described serial ports transmission Data Identification was 0, described processor sent the low level of described humidity value to described D/A converter from this serial ports.
17, method according to claim 16, it is characterized in that, the change that described serial ports sends Data Identification is in the serial ports interruption subroutine, after serial ports sends data, jumps into the serial ports interruption subroutine automatically and finishes.
