Description

Technical Field

[0001] This disclosure relates to computer technology, and in particular to a device control method and apparatus, a data acquisition system, equipment, and medium. Background Technology

[0002] Control methods for terminal devices typically include the following two types: The first is to directly send control commands to the terminal device using peripheral input devices (such as a mouse, keyboard, etc.); the second is to send control commands to the terminal device via a network using other terminal devices to instruct the terminal device to perform corresponding operations. For example, when a pulse camera acquires images, the acquisition action is usually controlled by a control program loaded on a host computer. Operators generally issue operation commands to the host computer using a mouse or keyboard, and the pulse camera's control program translates these commands into control commands for the pulse camera to control its acquisition action; alternatively, operators can input operation commands on other terminal devices using a mouse or keyboard and send them to the host computer via a network.

[0003] The first method requires a terminal device with a display, while the second requires an additional terminal device and a network connecting the two. Both methods also require input devices such as a mouse and keyboard. However, there are special scenarios in practice. For example, particle drop experiments need to be filmed in a sealed container where there is no display or input device and no network. In such cases, the two device control methods mentioned above cannot be applied. Furthermore, there are other special scenarios in practice, such as filming the trajectory of an aircraft in flight. During this process, the pilot does not have the time or energy to operate a keyboard or mouse to issue commands to the terminal device.

[0004] It is evident that the equipment control methods in related technologies are cumbersome to operate and easily limited by peripheral devices, failing to meet the needs of some special scenarios. Summary of the Invention

[0012] In some embodiments, the data acquisition device and terminal equipment are housed in a closed enclosure.

[0017] Based on the device control method and apparatus, data acquisition system, electronic device, and storage medium provided in the above embodiments of this disclosure, a control signal can be generated by shorting the data receiving line and data transmitting line of the logic gate circuit port through a control switch, and then sent to the serial port of the first terminal device through an adapter cable.

[0034] Figure 1 A schematic diagram of the system architecture to which the device control method of this disclosure applies is shown, such as... Figure 1 As shown, terminal device 110 and camera 120 are housed in a sealed container 130. Terminal device 110 contains the driver program for camera 120, used to control camera 120 to capture image data of falling particles. The serial port of terminal device 110 is connected to the Universal Serial Bus (USB) port of adapter cable 140. The other end of adapter cable 140 is a Transistor-Transistor Logic (TTL) port. Control switch 150 connects to the data receive line (Receive External Data, RXD) and data transmit line (Transmit Data, TXD) in the TTL port. When control switch 150 is closed, the data receive line and data transmit line are shorted, and the TTL port generates a "0000" signal, which is then sent to the serial port of terminal device 110 via adapter cable 140. When the driver program detects that the serial port has received a "0000" signal, it can send a start command to camera 120 to instruct camera 120 to acquire data. This enables control of the terminal device and camera via the terminal device's serial port.

[0035] The following is combined with Figure 2The device control method of this disclosure is illustrated by way of example. Figure 2 A flowchart of one embodiment of the device control method of this disclosure is shown, as follows: Figure 2 As shown, the process includes the following steps.

[0036] Step 210: Monitor the communication status of the serial port.

[0037] In this embodiment, the first terminal device is pre-installed with software programs, and the serial port of the first terminal device is connected to the serial communication port of the adapter cable. The other end of the adapter cable is a logic gate circuit port. The data receiving line and data sending line of the logic gate circuit port are respectively connected to the two ends of the control switch. When the control switch is closed, the data receiving line and the data sending line are short-circuited.

[0038] As an example, the serial port of the first terminal device can be a USB interface for receiving control signals, and the control switch can be a power switch. The first terminal device can monitor the communication status of the serial port in various ways, such as through pre-installed serial port monitoring software, which could be a serial port assistant tool; or, for example, the software program can integrate a serial port monitoring module to monitor the communication status of the serial port of the first terminal device.

[0039] Step 220: In response to the control signal received by the serial port, execute the preset instructions in the software program.

[0040] In this embodiment, when the serial port receives a control signal, the first terminal device can respond to the control signal and execute the preset instructions in the software program to achieve the corresponding operation.

[0041] In this embodiment, the preset instructions can include one or more of various types, each corresponding to a different function. For example, they can include data processing instructions, data transmission instructions, program control instructions, input-output instructions, and status management instructions, etc., and are typically preset according to requirements. The preset instructions can also employ various execution methods, such as single execution, continuous execution, and interval execution.

[0042] Typically, a logic gate circuit port includes a data receive line, a data transmit line, and a ground line. When the data receive line and the data transmit line are shorted, the logic gate circuit generates a "0000" signal. In this embodiment, the "0000" signal can be used as a control signal, which can be generated by shorting the data receive line and the data transmit line.

[0043] Figure 3 This is a schematic diagram showing the connection of the adapter cable, the first terminal device, and the control switch in this embodiment, as shown below. Figure 3As shown, the serial communication port (i.e., USB interface) of the adapter cable 310 is connected to the serial port of the first terminal device 320. The data transmission line 311 and data reception line 312 of the logic gate circuit port connected to the adapter cable 310 are respectively connected to the two ends of the control switch 330. When the control switch 330 is closed, the data transmission line 311 and the data reception line 312 are shorted, which generates a "0000" control signal and sends it to the serial port of the first terminal device 320. The control switch 330 controls the logic gate circuit port to generate control signals, which is simple to operate and has a high fault tolerance, making the device control method more flexible to be applied to various scenarios.

[0044] In a specific example, the first terminal device can serve as the host computer for the pulse camera, pre-installed with the pulse camera's control program. The host computer and the pulse camera are mounted on the test aircraft to capture the aircraft's flight trajectory. The host computer's serial port is connected to a control switch via an adapter cable to receive control signals. When the aircraft is in flight, the pilot simply presses the control switch to send a control signal to the host computer. The host computer responds to the control signal and sends a shooting command to the pulse camera using the control program, allowing the pulse camera to acquire images, making operation more convenient.

[0045] The device control method provided in this embodiment generates a control signal by shorting the data receiving and data transmitting lines of a logic gate circuit port using a control switch. This control signal is then transmitted to the serial port of a first terminal device via an adapter cable. When the first terminal device detects that the serial port has received the control signal, it can execute preset instructions in the software program to achieve the corresponding function. This method controls the software program on the first terminal device without requiring a network connection or output device. On the one hand, it overcomes the dependence of the device control process on networks and peripheral devices, making the device control method applicable to more scenarios. On the other hand, it simplifies the control method and improves operational convenience.

[0046] In some optional embodiments of this example, the first terminal device and the second terminal device are communicatively connected, and the operation represented by the preset instruction is to send a control instruction to the second terminal device to control the second terminal device.

[0047] As an example, when the control switch is closed, the serial port of the first terminal device receives a control signal. At this time, a control command can be sent to the second terminal device through a software program to control the second terminal device. For example, the first terminal device can send device control commands to the second terminal device, such as power-on or power-off commands, to turn the second terminal device on or off. Alternatively, the first terminal device can also send program execution commands to the second terminal device to control the second terminal device to run a corresponding program, such as data processing, data acquisition, or data transmission.

[0048] In this embodiment, a control signal can be sent from the serial port of the first terminal device to the second terminal device, thereby controlling the first terminal device to send control commands to the second terminal device, and thus controlling the second terminal device to perform the corresponding operation. This simplifies the device control operation, making the device control method of this disclosure applicable to some application scenarios with harsh conditions, such as inconvenient operation or closed environments without network.

[0049] In some optional implementations of this embodiment, the second terminal device is used to collect data, and the control instructions include data collection instructions to instruct the second terminal device to collect data.

[0050] In this embodiment, the second terminal device can be various types of sensors, such as image sensors, inertial sensors, sound sensors, distance sensors, etc., used to acquire various types of data.

[0051] Optionally, the data acquisition instruction can be a single acquisition instruction, used to instruct the second terminal device to acquire data once; it can also be a continuous acquisition instruction, used to instruct the second terminal device to acquire data continuously; or it can be an interval acquisition instruction, used to instruct the second terminal device to acquire data once at certain intervals.

[0052] The first terminal device can act as the host computer of the second terminal device. Through the control program, it can convert the operation instructions issued by the user into control instructions for the second terminal device and send the control instructions to the second terminal device to instruct the second terminal device to perform the corresponding operation. For example, when the serial port of the first terminal device receives a control signal, the control program running on it can send a data acquisition instruction to the second terminal device to instruct the second terminal device to acquire data.

[0053] In this embodiment, the control program on the first terminal device can be controlled through the serial port of the first terminal device, thereby controlling the second terminal device to collect data. This simplifies the data collection process and is applicable to demanding application scenarios such as inconvenient operation or closed environments without network access.

[0054] In some optional implementations of this embodiment, monitoring the communication status of the serial port of the first terminal device using a serial port monitoring program includes: monitoring the communication status of the serial port of the first terminal device using a software program or serial port monitoring software pre-installed on the first terminal device.

[0055] As an example, the software program may have a pre-integrated serial port monitoring module for monitoring the communication status of the first terminal device; or, the first terminal device may have pre-installed serial port monitoring software for monitoring the communication status of the first terminal device.

[0056] In this embodiment, software programs or serial port monitoring software can be selected to monitor the serial port of the first terminal device according to actual needs, which can further improve the flexibility of the device.

[0057] The following is for reference. Figure 4 , Figure 4 A schematic diagram of the architecture of an embodiment of the data acquisition system of this disclosure is shown, such as... Figure 4 As shown, the system includes: a data acquisition device 410, a terminal device 420, an adapter cable 430, and a control switch 440. One end of the adapter cable 430 is a logic gate circuit port, and the other end is a serial communication port. The logic gate circuit port is connected to the control switch 440, and the serial communication port is connected to the serial port of the terminal device 420. The control switch 440 is used to control the shorting and disconnection of the data receiving line and the data transmitting line in the logic gate circuit port. When the data receiving line and the data transmitting line are shorted, the logic gate circuit port generates a control signal and sends the control signal to the serial port through the adapter cable 430. The terminal device 420 runs the control program of the data acquisition device 410. When the serial port receives the control signal, the terminal device 420 executes the preset instruction in the control program. The preset instruction is to send an acquisition instruction to the data acquisition device 410 to instruct the data acquisition device 410 to acquire data.

[0058] In this embodiment, a control signal is generated by the logic gate circuit port of the control switch control adapter and sent to the serial port of the terminal device. The control program on the terminal device responds to the control signal and sends a data acquisition command to the data acquisition device to instruct the data acquisition device to acquire data. This realizes the control of the data acquisition process through the serial port without the need for a network or other peripheral devices. This simplifies the operation process and overcomes the dependence of the control process on the network or peripheral devices. It helps to expand the application scenarios of the data acquisition system disclosed in this invention, especially in some relatively harsh scenarios such as those without a network or with inconvenient operation.

[0059] The following is for reference. Figure 5 , Figure 5 A schematic diagram of the architecture of yet another embodiment of the data acquisition system of this disclosure is shown, such as... Figure 5 As shown, the data acquisition system includes a data acquisition device 510, a terminal device 520, a closed enclosure 530, and a control device 540. The data acquisition device 510 and the terminal device 520 are housed within the closed enclosure 530. The control device 540 supplies power to the data acquisition device 510 and the terminal device 520, and a control switch (not shown) is located on the control device 540.

[0060] In practice, some experimental scenarios require data acquisition devices and terminal equipment to be housed in a sealed enclosure to prevent interference with the experimental process. For example, particle drop experiments need to be conducted in a sealed container, using a high-speed pulse camera to film the particle drop process. Power is supplied to the terminal equipment, high-speed pulse camera, and other experimental equipment from a control device outside the sealed container. Since the data acquisition device and terminal equipment are located in a completely sealed environment, network signals are completely blocked, making it impossible to control the data acquisition device via the network. Furthermore, operators are not allowed to enter the sealed enclosure to control the data acquisition device through human-computer interaction, thus preventing commands from being issued to the terminal equipment via the network or other peripheral devices. In this embodiment, by modifying the logic gate circuit port, the data receiving and data transmitting lines of the logic gate circuit port are retained and connected to the two ends of a control switch (e.g., a power switch) on the control device. When the control switch is open, no control signal is generated to control the data acquisition device; when the control switch is closed, i.e., the data receiving and data transmitting lines are short-circuited, the logic gate circuit port generates a control signal and sends it to the serial port of the terminal equipment. Optionally, the serial port on the terminal device used to connect a mouse, printer, or keyboard can be used as the port to receive the control signal. Furthermore, the serial port monitoring software (e.g., a serial port assistant) pre-installed on the terminal device and the software program that controls the data acquisition device based on the control signal can be configured separately or integrated into the same software program. Upon receiving the control signal, the software program can send an acquisition command to the data acquisition device, instructing it to acquire image data.

[0061] With the data acquisition system of this embodiment, when the operator observes that data needs to be acquired, he can use the control switch set on the control device to short-circuit the data transmission line and the data reception line to generate a control signal and send it to the serial port of the terminal device. The control program running on the terminal device responds to the control signal and sends an acquisition command to the data acquisition device (e.g., a high-speed pulse camera) to instruct the data acquisition device to acquire data, thereby realizing the control of the data acquisition device in a closed environment through the serial port.

[0062] In this embodiment, the terminal device and data acquisition device housed in a closed enclosure can meet the needs of some special experimental scenarios, and the data acquisition process can be controlled via a serial port. Placing the control switch on the control device helps improve the integration level of the data acquisition system; operators can manipulate the control device to generate control signals, further enhancing operational convenience.

[0063] In some embodiments, the data acquisition device includes any of the following: a pulse camera, a high-speed camera, a vision camera, an audio player, a video player, a navigation device, a fixed-position terminal, an entertainment unit, a smartphone, a communication device, a mobile device, a device in a motor vehicle, a vehicle-mounted camera, a mobile phone camera, an action or wearable camera, a traffic camera, an industrial inspection camera, a camera mounted on a flying object, a medical camera, a security camera, or a home appliance camera.

The apparatus is applied to a first terminal device pre-installed with software. The serial port of the first terminal device is connected to the serial communication port of an adapter cable. The other end of the adapter cable is a logic gate circuit port. The data receiving line and data transmitting line of the logic gate circuit port are respectively connected to both ends of a control switch. When the control switch is closed, the data receiving line and the data transmitting line are short-circuited, such as... Figure 6 As shown, the device includes: a monitoring unit 610 configured to monitor the communication status of the serial port; and a response unit 620 configured to execute preset instructions in the software program in response to a control signal received by the serial port; wherein, in response to a short circuit between the data receiving line and the data transmitting line, a control signal is generated at the logic gate circuit port.

[0065] In one embodiment, the first terminal device and the second terminal device are communicatively connected, and the operation represented by the preset instruction is to send a control instruction to the second terminal device to control the second terminal device.

[0066] In one embodiment, the second terminal device is used to collect data, and the control instructions include data collection instructions to instruct the second terminal device to collect data.

[0067] In one embodiment, the monitoring unit is further configured to monitor the communication status of the serial port of the first terminal device using a software program or serial port monitoring software pre-installed on the first terminal device.
