Because the main control MCU is connected with the communication box 116 by a serial port data line 115, and the communication box 116 is connected with the computer 118 by a USB data line 117. In order to ensure that the computer 118 can identify the data, the communication box 116 also converts the measurement data stored in the FLASH memory sent by the probe 119 into data of the USB protocol, and then uploads the data to the computer 118, so that the computer 118 receives, processes and stores the data.

Preferably, the probe 119 works on the sea bottom, and due to the limitation of the special underwater high-pressure environment, the detachability and the simplicity of transmission of the probe 119, the probe 119 is generally reserved with only one single-core output interface. In order to ensure the stability of data communication, the present embodiment provides a new transmission method: a single-wire two-way transmission mode, thereby realizing data communication among the probe 119, the communication box 116 and the computer 118.

As shown in fig. 2, a first single-wire bidirectional transmission module and a USB controller are disposed in the communication box 116. A second single-wire bidirectional transmission module is provided in the probe 119.

The second single-wire bidirectional transmission module is connected with the first single-wire bidirectional transmission module, and the first single-wire dual-wire transmission module is connected with the USB controller.

The main control MCU is connected with the second single-wire bidirectional transmission module.

Preferably, when the battery 21 in the probe 119 is connected to the circuit board 11, the DS32kHz temperature compensation clock vibration module starts to operate and generates an oscillation signal to be sent to the main control MCU, so that the main control MCU initializes system parameters and starts to operate, and detects an interrupt signal of the second single-wire bidirectional transmission module in real time; at this time, the three-axis acceleration sensor array, the signal conditioning circuit, and the 24-bit ADC module in the sensor module 5 are not started, and the probe 119 is in a low power consumption state. That is, after the probe 119 is powered on, the probe 119 is put into a low power consumption state, so that the system power consumption is reduced, the service life of the battery 21 of the probe 119 can be prolonged, the cost is saved, and frequent replacement of the battery 21 can be avoided.

The computer 118 is connected to the first single-wire and two-wire transmission module through the USB controller, and is configured to issue a control command to the communication box 116, and transmit the control command to the main control MCU through the second single-wire bidirectional transmission module.

When the main control MCU detects that the second single-wire bidirectional transmission module has an interrupt signal, that is, the computer 118 sends a control command to the probe 119 through the communication box 116, obtains the control command, and controls the corresponding device to operate according to the control command.

Preferably, the control commands generally include a get instrument information command, a parameter setting command, a data upload command, a system reset command, and the like. The instrument information refers to instrument information parameters of the probe 119, and the instrument information parameters are uploaded to the computer 118, so that the computer can control the probe 119 according to the instrument information parameters of the probe 119.

Setting parameters, which mainly comprise the sampling rate, the serial number, the time range of data acquisition and the like of the probe 119; the setting range of the sampling rate can be from one time per hour to one time per second, the serial number supports an English letter and number combined mode, the time range of the sampling data refers to the starting time and the ending time of the collected data, and the time is based on the time of a DS32kHz temperature compensation clock vibration module on a circuit board.

The system reset is for resetting the probe 119. For example, when the probe 119 receives a system reset command sent by the communication box 116, the hardware watchdog is used to implement the reset operation of the master MCU.

The data uploading means that the measurement data in the FLASH memory is uploaded to the computer 118 through the communication box 116.

When the main control MCU receives an instrument information acquisition command sent by the second single-wire bidirectional transmission module, the main control MCU sends the instrument information of the probe 119 to the communication box 116 through the second single-wire bidirectional transmission module, so that the first single-wire bidirectional transmission module in the communication box 116 converts the instrument information through the USB controller and sends the converted instrument information to the computer 118; and after the data transmission is finished, the main control MCU enters a waiting command interrupt state again.

When the main control MCU receives the parameter setting command sent by the second single-wire bidirectional transmission module, the main control MCU module obtains parameter information data according to the parameter setting command, and sets the parameter of data sampling in the probe 119. The parameters include sampling start time, sampling frequency, sampling end time and other parameters.

Preferably, the data sampling operation of the probe 119 of the present invention is accomplished by timing. The computer 118 issues parameter setting commands to the probe 119, and implements the setting of parameters and stores them in the probe 119. Once the master control MCU detects that the time reaches the sampling start time, the master control MCU controls the three-axis acceleration sensor array in the sensor assembly 5 to start data sampling, and closes each device of the sensor assembly 5 until the sampling is completed, so that the probe 119 enters a low power consumption state.

Meanwhile, the triaxial acceleration sensor array also sends the sampled sensor signal to the signal conditioning circuit, so that the signal conditioning circuit converts the sensor signal into an analog signal and sends the analog signal to the 24-bit ADC module. The 24-bit ADC module converts the analog signal into a digital signal and sends the digital signal to the main control MCU, and the digital signal is stored in the FLASH memory. In this way, when a data upload command sent by the computer 118 is subsequently received, the data stored in the FLASH memory can be uploaded to the computer 118 through the communication box 116.

When the master control MCU receives the data upload command sent by the second single-wire bidirectional transmission module, the master control MCU uploads the data in the FLASH memory to the computer 118 through the communication box 116. Preferably, when the data is uploaded, uploading of the measurement data in a specific time period can also be realized. Such as by setting time parameters for downloading data, including the start time, end time, etc. of the data, in the data upload command. Thus, after receiving the data uploading command, the main control MCU matches the data from the FLASH memory according to the time parameter of the downloaded data, and uploads the data to the computer 118 through the communication box 116.

When the main control MCU receives the system reset command sent by the second single-wire bidirectional transmission module, the main control MCU first stores the instrument parameters of the system and sends a control signal to the hardware watchdog, so that the hardware watchdog generates a reset signal to the main control MCU, the main control MCU is initialized to reset, and after the initialization is completed, the probe 119 enters a wait command interrupt state, i.e., a low power consumption state.

Preferably, in order to ensure that the power consumption of the system is low, after the main control MCU is powered on, the probe 119 enters an initialization program and after the initialization is completed, the sensor assembly 5 does not operate at this time, and the main control MCU monitors an interrupt signal of the second single-wire two-wire transmission module in real time, that is, the probe 119 enters a wait command interrupt state, that is, a low power consumption state, so that the operating time of the probe 119 is longer.

When the main control MCU detects that the second single-wire bidirectional transmission module has an interrupt signal, that is, the computer 118 issues a control command through the communication box 116: and the main control MCU receives the control command and executes corresponding operation according to the control command. After the corresponding control command is completed, the main control MCU controls the sensor assembly 5 to close, so that the probe 119 enters a low power consumption state again, that is, a command interrupt state is waited for, and enters a working state again until a new interrupt signal is detected or a set sampling start data is reached.

Preferably, the first single-wire bidirectional transmission module and the second single-wire bidirectional transmission module are also implemented by an interface chip LTC 2801. And the interface chip LTC2801 is used for converting the TTL electric signals into RS232 level signals and further uploading the measurement result data to the communication box 116.

Preferably, in this embodiment, a PS pin of the interface chip U is used to implement a DC (Direct Current) power supply for controlling the interface chip U and a MODE pin for controlling a data transceiving MODE of the interface chip.

Wherein, within the probe 119: the main control MCU is used as a main control center and is electrically connected with the second single bus control module, and is used for controlling the PS pin and the MODE pin of the interface chip LTC2801 so as to control the current data transceiving MODE.

Specifically, the method comprises the following steps: when the PS pin of the interface chip U is at a low level and the MODE pin is at a low level, the receiving MODE and the output MODE are both in a high-impedance state, the DC power supply is turned off, and the power consumption of the interface chip is the lowest at the moment and is only 1 uA.

When the PS pin of the interface chip U is at a low level and the MODE pin is at a high level, the receiving MODE is in a normal state, the output MODE is in a high-resistance state, the DC power supply is turned off, the receiving MODE enters an interception state, and the transmission of commands or data is waited;

when the PS pin is at high level and the MODE pin is at high level, the output MODE is started, and data can be normally output.

Preferably, the USB controller in the communication box 116 employs an FT232 chip. The MODE pin of the interface chip LTC2801 of the first single-wire bidirectional control module is controlled by the CBUS2 pin of the FT223 chip, so that the communication box 116 is always in a half-duplex operating state.

Preferably, when the computer 118 is connected to the probe 119 through the communication box 116 in this embodiment, the probe 119 is on the ground, that is, when the probe 119 is in the deep sea device, the attitude data of the deep sea device can be sampled and stored in the FLASH memory. When the probe 119 is at the surface, communication between the probe 119 and the computer 118 via the communications box 116 may be accomplished via the serial data line 115.

The invention can realize the dip angle measurement of deep sea equipment, can make the measuring result more accurate by setting up the triaxial acceleration transducer array, meanwhile, realize the communication of the probe 119 and computer 118 through the communication box 116, greatly improve the reliability of the communication and data transmission stability, have solved the problem of the prior art that the communication is unstable and cause the data to upload and fail, etc.; meanwhile, the invention enables the probe 119 to be in a low power consumption state when not working in a single-wire two-way transmission mode, thereby reducing the system power consumption and prolonging the working time of the probe 119.
