[0054] Figure 1 is a connection diagram of the line casting instrument body, battery pack and mobile terminal in some embodiments of the present application. As shown in Figure 1, the line casting instrument 200 includes a line casting instrument body 30 and a battery pack 20, wherein the line casting instrument body 30 includes a controller 31 and multiple lasers 32, and the battery pack 20 includes a communication module 21. The communication module 21 can be a wireless communication module or a wired communication module. The communication module 21 can realize the communication connection between the battery pack 20 and the mobile terminal 100. Among them, the wireless communication module can include but is not limited to WIFI, Bluetooth, Zigbee, etc. The mobile terminal 100 includes but is not limited to mobile phones, portable notebooks, Pads, wearable devices and other interactive terminals with display and input functions. The battery pack 20 and the line casting instrument body 30 can be connected by wire, and the connection line can include a power supply line and a signal transmission line.

[0055] In this embodiment, a control method for a line shooting instrument is provided. This control method can be applied to a controller 31 of a line shooting instrument body 30. The controller 31 can be, but is not limited to, a central processing unit (CPU), an MCU, a single-chip microcomputer, a digital signal processor (DSP), or other computing device with data processing and data storage capabilities. FIG2 is a flow chart of the control method for the line shooting instrument body of some embodiments of the present application. As shown in FIG2, the flow chart includes the following steps:

[0056] Step S201: receiving a laser control signal sent by a battery pack. The laser control signal is obtained by the battery pack based on a laser control instruction code received by a communication module. The laser control instruction is sent by a mobile terminal.

[0057] Control software can be installed on the mobile terminal to control the linecaster. The control software may include an interactive interface through which a user can input laser control instructions for the linecaster. Laser control instructions may include the target laser to be operated and the type of operation. In some embodiments, the laser control instructions also include operating parameters. Specifically, laser control instructions may include, but are not limited to, instructions for setting or adjusting the laser power of a laser, instructions for turning a specific laser on or off, instructions for controlling the laser's control mode, instructions for selecting a horizontal or vertical laser line, and the like.

[0058] After the user enters a laser control command for the laser projector on the interactive interface, the mobile terminal transmits the command to the battery pack. The battery pack receives the command via the communication module and encodes it to generate a corresponding laser control signal. The encoding method can be predetermined and includes, but is not limited to, high- and low-level encoding and encoding based on communication protocols.

[0059] Specifically, the encoding based on the communication protocol may include but is not limited to various serial bus protocols such as RS485, USB, etc.

[0060] Specifically, high and low level coding refers to presetting the correspondence between different laser control instructions and different high and low level sequences. For example, 1 is high level, 0 is low level, the 10101010 level sequence represents turning on the laser horizontal line, and 11111111 represents turning on the laser vertical line, etc.

[0061] The battery pack sends the laser control signal to the line casting instrument body through the signal transmission line between the battery pack and the line casting instrument body.

[0062] Step S202: Decode the laser control signal to obtain the laser control instruction.

[0063] After receiving the laser control signal, the line casting instrument decodes it based on the encoding method in step S201 to obtain the corresponding laser control instruction.

[0064] Step S203: Based on the laser control instruction, control the corresponding laser to perform the corresponding laser control operation.

[0065] According to the target laser to be operated and the type of operation contained in the laser control instruction, the corresponding operation is performed on the target laser. The specific operation may include turning on the laser, turning off the laser, determining the control mode of the laser, setting the laser power of the laser, etc.

[0066] Through steps S201 to S203, a communication module is set in the battery pack, so that the line casting instrument body establishes a communication connection with the mobile terminal through the communication module, providing communication support for realizing remote control of the line casting instrument body; the laser control instruction sent by the mobile terminal is encoded and forwarded by the battery pack to the controller of the line casting instrument body, and the control instruction is converted into a laser control signal that can be received by the line casting instrument body; the controller decodes the laser control signal after receiving it to obtain the laser control instruction on the mobile terminal side; based on the laser control instruction, the corresponding laser is controlled to perform the corresponding laser control operation, thereby realizing remote operation of the line casting instrument through the mobile terminal, solving the problem that the operation control method of the line casting instrument does not meet the safety requirements of the operator in a complex environment and the operation efficiency is low.

[0067] In some embodiments, FIG3 is a flow chart of laser power control of a line caster in some embodiments of the present application. As shown in FIG3 , the flow chart includes the following steps:

[0068] Step S301 , determining whether the target power corresponding to the power information in the laser control instruction is equal to the preset power.

[0069] The laser control instructions of this embodiment include power information, which corresponds to the target power of the target laser. Specifically, the power information can be a target power value or parameter options related to the target power (such as high / medium / low power), and the parameter options can correspond to the target power value. When the target laser is controlled by a pulse signal (PWM duty cycle signal), the power information can also be the duty cycle data of the pulse signal, with different duty cycle data corresponding to different target power values.

[0070] The target power value is compared with the preset power to determine whether the target power is equal to the preset power. The preset power may be the power corresponding to when the laser is fully turned on.

[0071] Step S302: When the target power is equal to the preset power, a level signal is sent to control the corresponding laser to be turned on.

[0072] When the target power is equal to the preset power, the corresponding laser can be directly controlled to be fully turned on by sending a level signal.

[0073] Specifically, a switch circuit may be included between the controller and the laser. The controller sends a corresponding level signal to the switch circuit, and the switch circuit controls the laser to be fully turned on according to the level signal, so that the power of the laser reaches the target power.

[0074] Step S303: When the target power is less than the preset power, a pulse signal is sent to control the corresponding laser to be turned on and off, and the duty cycle of the pulse signal corresponds to the target power.

[0075] If the target power is less than the preset power, a pulse signal corresponding to the target power is generated, with a duty cycle corresponding to the target power. The pulse signal is sent to the switching circuit, which controls the laser on and off according to the pulse signal to ensure that the laser power reaches the target power.

[0076] Through steps S301 to S303, it is determined whether the target power corresponding to the power information in the laser control instruction is equal to the preset power. When the target power is equal to the preset power, a level signal is sent to control the corresponding laser to be fully turned on; when the target power is less than the preset power, a pulse signal corresponding to the target power is generated to control the corresponding laser to be turned on and off, so that the power of the laser reaches the target power, meeting the needs of remote setting or adjustment of the laser power and laser brightness.

[0077] In some embodiments, FIG4 is a flow chart of determining a laser control mode of a line caster in some embodiments of the present application. As shown in FIG4 , the flow chart includes the following steps:

[0078] Step S401 : determining whether the control mode of the laser is a pulse mode based on the mode information in the laser control instruction.

[0079] The laser control instructions in this embodiment contain mode information, which can be either pulse mode or level mode. Pulse mode uses a pulse signal containing duty cycle information to control the laser's on / off state, resulting in pulsed laser emission for easy detection by the detector. Level mode uses a high-level or low-level signal to fully turn the laser on or off. When fully on, the laser emits continuously. In practical applications, the operator can set the laser control mode in a mobile terminal and send it to the laser projector. The laser projector then determines whether the laser's control mode is pulse mode based on the mode information in the laser control instruction.

[0080] Step S402: When the control mode is the pulse mode, a pulse signal is sent to control the corresponding laser to be turned on or off.

[0081] When the control mode is pulse mode, a corresponding pulse signal can be generated for an operating laser based on the target power of the laser. The duty cycle of the pulse signal corresponds to the target power. The pulse signal is sent to the switching circuit corresponding to the laser. The switching circuit controls the laser on and off based on the pulse signal, so that the laser is emitted in a pulsed manner corresponding to the duty cycle.

[0082] For a laser in an idle state, when a laser control signal is subsequently received, a corresponding pulse signal may be generated to perform a laser control operation on the laser.

[0083] Step S403: When the control mode is not the pulse mode, a level signal is sent to control the corresponding laser to be turned on or off.

[0084] When the control mode is not the pulse mode, the laser is controlled using a level signal. For a laser in an operating state, a corresponding level signal can be generated, and the level signal is sent to the switch circuit corresponding to the laser. The switch circuit controls the laser to be turned off according to the level signal. For a laser in an idle state, a corresponding level signal can be generated, and the level signal is sent to the switch circuit corresponding to the laser. The switch circuit controls the laser to be turned on according to the level signal.

[0085] When other laser control signals are subsequently received, corresponding control operations are also performed through the level signal.

[0086] Through steps S401 to S403, based on the mode information in the laser control instruction, it is determined whether the control mode of the laser is the pulse mode. When the control mode is the pulse mode, a pulse signal is sent to control the corresponding laser to be turned on or off, so that the laser is emitted in a pulse manner with a corresponding duty cycle to meet the detection requirements of the detector; when the control mode is not the pulse mode, a level signal is sent to control the corresponding laser to be turned on or off to meet the continuous emission requirements of the laser.

[0087] In some embodiments, FIG5 is a flow chart of laser on-off control of a line caster in some embodiments of the present application. As shown in FIG5 , the flow chart includes the following steps:

[0088] Step S501: Determine whether the laser control instruction is to turn off the laser.

[0089] Step S502: When it is determined that the laser control instruction is to turn off the laser, a shutoff signal is sent to all lasers to control the corresponding lasers to turn off.

[0090] The laser shutdown command is a comprehensive shutdown command. When it is determined that the received laser control command is to shut down the laser, a shutdown signal is sent to the switch circuits corresponding to all lasers. This shutdown signal can be a level signal or a pulse signal (with a duty cycle of 0), and the switch circuit controls the corresponding laser to shut down. Before shutting down, the operating status of each laser can be saved, including whether the laser is in an operating state, whether the laser is pulse controlled, and the laser's operating power.

[0091] Step S503: When it is determined that the laser control instruction is not to turn off the laser, it is determined whether the laser is to be turned on.

[0092] Step S504: When it is determined that the laser control instruction is to turn on the laser, a turn-on signal is sent to the corresponding laser. The turn-on signal is used to restore the laser to a state before it was turned off.

[0093] When it is determined that the laser control instruction is to turn on the laser, a conduction signal is sent to the switch circuit corresponding to the laser that was in the working state before being turned off according to the saved working state of each laser before being turned off. The conduction signal is used to restore the working state of the laser before being turned off.

[0094] Specifically, the conduction signal may be a level signal or a pulse signal.

[0095] In a specific embodiment, the initial state of the laser is that the vertical line is turned on and the horizontal line is turned off. The mobile terminal sends an instruction to turn off the laser to the line projector, and all lasers are turned off. Then the mobile terminal sends an instruction to turn on the laser to the line projector, and a conduction signal is sent to the switch circuit corresponding to the laser corresponding to the vertical line to turn on the laser corresponding to the vertical line.

[0096] Through steps S501 to S504, by determining whether the laser control instruction is to turn off the laser, if it is determined that the laser control instruction is to turn off the laser, a shutdown signal is sent to all lasers to control the corresponding lasers to turn off, all lasers are quickly turned off, and the laser shutdown efficiency is improved; by determining whether the laser control instruction is to turn on the laser if it is not determined that the laser control instruction is to turn on the laser, if it is determined that the laser control instruction is to turn on the laser, a turn-on signal is sent to the corresponding laser, and the turn-on signal is used to restore the state of the laser before it is turned off. By saving the working state of each laser before it is turned off, the efficiency of restoring the working state of the laser is improved.

[0097] In some embodiments, FIG6 is a flow chart of laser line control of a line projector in some embodiments of the present application. As shown in FIG6 , the flow chart includes the following steps:

[0098] Step S601 : determining a target laser from a plurality of lasers based on the operation target information in the laser control instruction.

[0099] The laser control instructions of this embodiment include operation target information, which corresponds to a target laser. Specifically, the operation target information may include, but is not limited to, the selection and control of different laser lines. Specifically, options may include a horizontal line, a single vertical line, two vertical lines, or full on. Based on the operation target information in the laser control instruction, the target laser corresponding to the laser line to be activated can be determined from among multiple lasers.

[0100] Step S602: Sending a turn-on signal to the target laser to control the target laser to turn on.

[0101] Send a conduction signal to the switch circuit corresponding to the target laser, and the switch circuit controls the target laser to conduct. The conduction signal can be a level signal or a pulse signal.

[0102] Through steps S601 to S602, based on the operation target information in the laser control instruction, a target laser is determined from multiple lasers, and a conduction signal is sent to the target laser to control the conduction of the target laser, thereby realizing remote laser line control and meeting the use requirements of laser lines in different directions and different numbers.

[0103] In some embodiments, FIG7 is a flow chart of the laser status display of the line caster in some embodiments of the present application. As shown in FIG7 , the flow chart includes the following steps:

[0104] Step S701: Acquire laser status information of each laser.

[0105] While controlling each laser to perform the corresponding laser control operation, the laser status information of each laser is obtained. The laser status information may include but is not limited to whether each laser is in a working state, whether the laser is pulse controlled, the working power of the laser, the laser line opening state, etc.

[0106] Step S702 : Based on a predetermined coding method, the laser status information is converted into a corresponding laser status signal and sent to the battery pack. The laser status signal is decoded by the battery pack and then sent to the mobile terminal for display based on the communication module.

[0107] The laser status information is converted into a corresponding laser status signal based on a predetermined encoding scheme, which may be the encoding scheme determined in step S201. The laser status signal is transmitted to the battery pack via a signal transmission line between the laser projector body and the battery pack. The battery pack decodes the laser status signal to obtain the corresponding laser status information. The laser status information is transmitted to the mobile terminal via a communication module, which can be displayed on the mobile terminal using display software. The display software and control software can be combined into display control software.

[0108] Through steps S701 to S702, the laser status information of each laser is obtained, and the laser status information is converted into a corresponding laser status signal and sent to the battery pack. After decoding, the battery pack sends it to the mobile terminal for display based on the communication module, thereby realizing remote acquisition of the laser status information of the line caster placed in a complex environment, providing effective reference information for the operator's laser control, and providing real-time feedback information for the laser control operation, thereby improving the efficiency and accuracy of laser control.

[0109] The present application also provides a method for controlling a line caster applied to a mobile terminal. The line caster includes a line caster body and a battery pack, and the line caster body includes a controller and multiple lasers. ， The battery pack includes a communication module, through which the line casting instrument body communicates with the mobile terminal.

[0111] The user can input laser control instructions for the linecasting instrument on the interactive interface of the control software. The laser control instructions may include the target laser to be operated and the type of operation. In some embodiments, the laser control instructions also include operating parameters.

[0112] Step S802: Based on the communication module, the laser control instruction is sent to the battery pack. The laser control instruction is converted into a laser control signal after being encoded by the battery pack and sent to the laser projection instrument body.

[0113] The battery pack receives laser control commands sent by the mobile terminal based on the communication module and encodes the laser control commands to obtain corresponding laser control signals. The encoding method can be predetermined, including but not limited to high and low level encoding, encoding based on the communication protocol, etc.

[0114] Through steps S801 to S802, a communication module is set in the battery pack, so that the line casting instrument body establishes a communication connection with the mobile terminal through the communication module, providing communication support for realizing remote control of the line casting instrument body; the laser control instruction sent by the mobile terminal is encoded and forwarded by the battery pack to the controller of the line casting instrument body, and the control instruction is converted into a laser control signal that can be received by the line casting instrument body; the controller decodes the laser control signal after receiving it to obtain the laser control instruction on the mobile terminal side; based on the laser control instruction, the corresponding laser is controlled to perform the corresponding laser control operation, thereby realizing remote operation of the line casting instrument through the mobile terminal, solving the problem that the operation control method of the line casting instrument does not meet the safety requirements of the operator in a complex environment and the operation efficiency is low.

This information allows operators to control the battery pack accordingly. For example, if the displayed battery temperature exceeds a certain threshold, a high-temperature alarm can be activated or the laser can be shut down.

[0127] Through steps S1001 to S1002, the battery status information sent by the battery pack based on the communication module is received and displayed, so that the working status of the battery pack can be remotely acquired and monitored, thereby improving the safety of the battery pack operation, providing effective reference information for the operator's battery control operation, and providing real-time feedback information for the battery control operation, thereby improving the efficiency and accuracy of battery control.

[0128] This embodiment further provides a line casting instrument, which includes a laser and a controller for switching the laser based on the control method of the line casting instrument in the above embodiment.

[0129] The line casting instrument of this embodiment receives the laser control signal sent by the battery pack through the controller, decodes the laser control signal, obtains the laser control instruction, and controls the corresponding laser to perform the corresponding laser control operation based on the laser control instruction, thereby realizing the remote operation of the line casting instrument through the mobile terminal, solving the problem that the operation control method of the line casting instrument does not meet the safety requirements of the operator in a complex environment and the operation efficiency is low, thereby improving the safety and environmental adaptability of the line casting instrument.
