[0033] The utility model discloses a sounding instrument simulation training system, which mainly includes: a host computer, a simulation host, a display and an operation keyboard. Among them, the host computer is connected to the simulation host through network communication. The simulation host is connected to a simulation circuit and a signal acquisition circuit. The simulation circuit is used to generate various forms of signals generated during the operation of the sounding instrument; the signal acquisition circuit is used to collect the level signals input by the keyboard or the level signals input by the chip interface.
[0034] According to the working principle of the sounding instrument, the sounding instrument sends sound waves through a transducer, and by recording the sending time of the sound waves and the receiving time of the reflected waves, and combining the sound wave propagation speed in water, the depth data can be obtained. Therefore, during the simulation of the working process of the sounding instrument, the simulation circuit only needs to give the time for the transducer to send and receive sound waves, and combine the preset underwater sound wave transmission speed to complete a depth simulation test.
[0035] In an embodiment of the present application, the simulation circuit gives a time signal in a pulse manner, and takes the time interval between two pulse signals as the time for the sound wave to propagate in water, simulating a normal working process of the sounding instrument.

[0038] Furthermore, in the present application, the analog host can be connected to a simulation circuit, and different signals can be simulated through different signal generators in the simulation circuit. It can also be connected to multiple simulation circuits, with each simulation circuit used to simulate the signal data generated during the operation of a depth sounder.
[0039] In a further embodiment of the present application, the signal acquisition board is used to simulate the virtual buttons of the analog host and the display and control terminal. The signal acquisition board collects the state changes of each switch position and sends them to the upper computer of the display and control terminal, where the upper computer performs logical calculations and presents them on the display and control terminal or enters them into the database. In order to make the interaction between the signal acquisition board and each switch position not restricted by the interface form, the signal acquisition circuit in the present application includes a main control module, a first interface module, a second interface module, and a third interface module. The main control module acquires input data through the first interface module, the second interface module, and the third interface module. The first interface module is used to receive data input through the PC serial port; the second interface module is used to receive data input through the USB interface; the third interface module is a multiplexed interface used to receive data input through the serial port or the CAN bus.
[0040] Specifically, as Figures 2-5As shown in the figure, the single-chip microcomputer model adopted by the main control module is STM32F103C8T6; the PC serial port chip model of the first interface module is MAX3232; the USB serial port chip model of the second interface module is CH375; the serial port chip model of the third interface module is MAX3485, and the CAN bus chip model of the third interface module is TJA1050. The PA9 pin of the single-chip microcomputer is connected to the T2IN pin of the chip MAX3232, the PA10 pin is connected to the R2OUT pin of the chip MAX3232, the T2OUT pin of the chip MAX3232 is connected to a pin of the externally extended row pin, and the R2IN pin of the chip MAX3232 is connected to another pin of the externally extended row pin; the PA11 pin of the single-chip microcomputer is connected to the D- pin of the chip CH375, and the PA9 pin is connected to the D+ pin of the chip CH375; the PB11 pin of the single-chip microcomputer is connected to the RO pin of the chip MAX3485, and the PB10 pin is connected to the DI pin of the chip MAX3485; the PB9 pin of the single-chip microcomputer is connected to the TXD pin of the chip TJA1050.
[0041] The MAX485 interface chip is a kind of RS-485 chip of Maxim Company. It works with a single power supply of +5V, and the rated current is 300μA. It adopts a half-duplex communication mode. It completes the function of converting TTL level to RS-485 level. The structure and pins of the MAX485 chip are very simple, and it contains a driver and a receiver inside. The RO and DI terminals are the output of the receiver and the input of the driver respectively. When connecting to the single-chip microcomputer, they only need to be connected to the RXD and TXD of the single-chip microcomputer respectively; the / RE and DE terminals are the enable terminals for receiving and sending respectively. When / RE is at logic 0, the device is in the receiving state; when DE is at logic 1, the device is in the sending state. Because MAX485 works in the half-duplex state, only one pin of the single-chip microcomputer is needed to control these two pins; the A and B terminals are the differential signal terminals for receiving and sending respectively. When the level of the A pin is higher than B, it means the data sent is 1; when the level of A is lower than the B terminal, it means the data sent is 0. The wiring is very simple when connecting to the single-chip microcomputer. Only one signal is needed to control the receiving and sending of MAX485. At the same time, a matching resistor is added between the A and B terminals, and a 100Ω resistor can generally be selected. It can draw power from the serial port and can drive max232 and max485 to achieve communication. The voltage is 5.16V without load, and it drops to about 3V after adding load.

The USB host mode of the CH375 supports various common USB full-speed devices, and the external single-chip microcomputer / DSP / MCU can communicate with the USB device through the CH375 according to the corresponding USB protocol.
[0044] In a preferred embodiment of the present application, the process of querying the switch bit status by the signal acquisition board is as follows: The analog host sends a switch key status query message to the signal acquisition circuit, and the data message is the number of the switch key to be queried. When the signal acquisition circuit receives the switch key status query message sent by the analog host, it sends back 1 reply message, and the data message is the number of the switch key being queried. If the current status of the switch and key is at the "0" level, a message identical to the query message is replied. If the current status of the switch key is at the "1" level, the following message is replied:
[0045] a. Switch key status "1→0" level change information message. During the working process, if the status of a certain switch key changes, the signal simulation circuit sends a switch key status change information message to the analog host, and the data message is the number of the switch key. If the status of the switch and key has a "1→0" level change, this message is replied.
[0046] b. Switch key status "0→1" level change information message. During the working process, if the status of a certain switch key changes, the signal acquisition circuit sends a switch key status change information message to the analog host, and the data message is the number of the switch key. If the status of the switch and key has a "0→1" level change, this message is replied.
[0047] In addition, the system further includes a display and a keyboard. The display is used as the output part of the system, and is used to display the working interface of the depth sounder, and display the signal data simulated by the simulation circuit and the operation data collected by the signal acquisition circuit on the working interface.
