Embodiment
Below in conjunction with drawings and Examples, the utility model and effect thereof are further elaborated.
We are known for the problem pointed out for background technology, and on the one hand, host computer CPU will realize man-machine interaction, and user selectes the communication transfer mode needed for it by host computer, to tackle different live demands; On the other hand, namely the hardware circuit in ADCP product will have RS232 interface circuit, has RS422 interface circuit again, and these two interface circuits can realize mutual handoff functionality, and can not interfere with each other.The implementation of this patent is illustrated according to above 2.
As shown in Figure 1, a kind of new A DCP digital adaptation custom system, comprise host computer CPU and slave computer ADCP, host computer CPU comprises the user interface user interface realizing user's man-machine interaction, user selectes required communication transfer mode by interface, slave computer ADCP receives the instruction of user communication mode, realizes automatically switching to corresponding communication modes interface;
Wherein, slave computer ADCP comprises RS232 interface circuit and RS422 interface circuit, RS232 interface circuit is connected with host computer CPU by external interface with RS422 interface circuit, RS232 interface circuit is connected with Micro-processor MCV by No. four single-pole single-throw switch (SPST)s with RS422 interface circuit, MCU is the microprocessor controlling custom system action, we select dsp processor, are controlled the break-make of No. four single-pole single-throw switch (SPST)s by Micro-processor MCV; The original state of described No. four single-pole single-throw switch (SPST)s is closure state.The original state of work original state Ying Shi No. tetra-single-pole single-throw switch (SPST) of system is closure state, and the original state by setting Micro-processor MCV pin controls the original state of No. four single-pole single-throw switch (SPST)s.When the original state of No. four single-pole single-throw switch (SPST)s is closure state, no matter host computer assigns RS422 transmission mode or RS232 transmission mode, the MCU of custom system all can receive the information transmitted by host computer in an initial condition, and what judge that user selectes is RS422 transmission mode or RS232 transmission mode, and then MCU controls No. four single-pole single-throw switch (SPST)s, close that communication port no, realize controlled, the selectable transmission mode of user.
Because ADCP product works usually in water environment, therefore external interface improves the safe application performance of equipment by grafting water joint; Use water joint to need again to consider the Cost Problems of water joint, the pin number of water joint is more, and corresponding hardware cost change can significantly be risen.At this, we are in order to reduce piece-ups, have employed the design of bridging line; Particularly, RS232 interface circuit and RS422 interface circuit adopt the mode of common sparing connecting line to be connected with external interface.As shown in Figure 1,422T_P and 232R in RS422 and RS232 interface circuit shares a connecting line, 422T_N and 232T shares a connecting line in concrete shared connecting line design; So external connection order wire number just reduces to 4 from 6, effectively reduces equipment cost.Here it is important to note that shared connecting line can not cause the mutual interference between interface circuit, what therefore we selected is two lines launched to host computer by ADCP in RS422 interface circuit, effectively can avoid the interference problem between two kinds of transmission modes.Because transmitting to ADCP by host computer when whole system is started working, signal is had on 422R_P and 422R_N of then RS422 interface circuit and on the 232R of RS232, again because RS422 interface chip is one-way passage, therefore the 232R signal of RS232 can not be transmitted by 422T_P and produce interference; When after a certain communication pattern of Systematic selection, broken by unwanted communication port by four path analoging switch, system there will not be communication interference issues.
As shown in Figure 2,3, 4, wherein we use MAX3232EUE and SN65C1168E respectively as RS232 interface chip and RS422 interface chip to concrete circuit implementations, and ADG1612 is as No. four single-pole single-throw switch (SPST)s.DSP_UART2_TXD wherein in Fig. 3, DSP_UART2_RXD are connected on DSP serial ports.IN_232_TX, IN_232_RX, IN_422_TX, IN_422_RX, controlled by DSP, and object is to realize whether closing of No. four hilted broadsword list Zheng Kaiguan.
Above embodiment is only exemplary; can't the utility model be limited to, should be understood that for a person skilled in the art, under technology enlightenment provided by the utility model; other equivalent modifications of making and improvement, all should be considered as protection domain of the present utility model.
