The software flow of system judges at first after program brings into operation whether house dog resets as shown in Figure 4, if reset, reads parameter, configuration correlation module is set, and the output controlled quentity controlled variable, enter the data acquisition process step then; If do not reset, the initialization single-chip microcomputer, dispose each functional module, and close all controlled quentity controlled variables, enter the data acquisition process step then.Send upstream data after the data acquisition process step is finished, judge whether to receive downlink command then, if receive, instruction verification, decoding, execution, single-chip microcomputer enters the low-power consumption standby pattern then; If do not receive, directly make single-chip microcomputer enter the low-power consumption standby pattern.After single-chip microcomputer entered the low-power consumption standby pattern, only reliable interruption came waken system, and entered into the data acquisition process step and circulate.
Software has used jtag interface in debug process.The RS-232 communication mode has been used in data acquisition and control, and the data pack protocol of RS-232 communication comprises frame beginning flag, frame identifier, data length, data, CRC check, frame end mark.Since the program space that 64kB is arranged of C8051 single-chip microcomputer, thus when realizing, the CRC program used the mode of tabling look-up, to improve arithmetic speed.
In the deep sea data acquisition control device, expansion to the many serial ports of system is than part and parcel, because central processing unit single-chip microcomputer C8051F020 input voltage is 3.3V, the I/O level of pin is the TTL logic level of 3.3V, and the RS-232 serial communication logic level of standard is ± 12V, so must use the signal level conversion chip to realize serial communication, adopt SP3243 and SPX3232 level conversion and chip for driving in the deep sea data acquisition control device as the serial communication interface of central processing unit.Sheet gating to 8 expansion serial ports is crossed 74ACT573 address latch and MM74HCT138M 3-8 code translator, the Q5 of 74ACT573 address latch, Q6, three of Q7 carry out the sheet choosing, eight tunnel outputs of MM74HCT138M and the enable port CSA of serial data communication four-way UART chip SC16C554, CSB, CSC, CSD, CSE, CSF, CSG, CSH links to each other, the data bus of SC16C554 (D0-D7) links to each other with the data bus (D1-D8) of 74ACT573 address latch, identical interface is all adopted in the i.e. data manipulation of 8 serial ports, adopts the mode of poll to carry out the read-write of serial ports.
The C8051F020 single-chip microcomputer passes through I
2C is connected with FM3130.FM3130 is the processor peripheral chip of embedded 64Kb ferroelectric memory, combines Nonvolatile ferroelectric memory FRAM and real-time clock RTC function.The FRAM storer can substitute SRAM, has and does not have time-delay write operation ability at a high speed; 12pF clock crystal commonly used is supported in alarm and programmable frequency clock output that RTC is integrated, can write down the leap year before in 2099.When bringing into use FM3130, internal register is calibrated according to the current time; In the use, regularly the register that reads date, week, Hour Minute Second correspondence obtains the current time on date, lay respectively at the register of 02H to 08H, the date time format is represented with binary-coded decimal, will constantly lock reading when procedure operation, counting changes in the process that prevents to read.
In order to prevent the interference of deep sea equipment, in output control circuit, added optical coupling isolator TLP521 to the C8051 single-chip microcomputer.Because the 20mA electric current that the C8051 single-chip microcomputer needs when the optocoupler conducting can't be provided,, constituted the Darlington transistor form with the output triode of optocoupler and driven relay so added a S8050NPN pipe at the output triode place of optocoupler.In order to prevent that the relay switch action from the time may produce electric spark, added choke induction at the power input of relay.
