Description

Technical Field

[0001] This application relates to the field of power supply control technology, and more specifically, to a power supply control system and a power supply control method. Background Technology

[0002] In 3D measurement and scanning equipment, articulated arm scanners, as a high-precision and portable measuring tool, are widely used in industrial manufacturing and quality inspection scenarios. The scanner component in an articulated arm scanner is usually detachably installed at the end of the articulated arm.

[0003] Currently, once the articulated arm scanner is connected to voltage, regardless of whether the articulated arm is powered on or whether the scanner components are actually connected to the articulated arm, the power interface of the scanner is always energized. The voltage connected to the articulated arm scanner continuously supplies power to the power interface of the scanner, which poses a power supply safety hazard to the power interface of the scanner when there is no load. It is very easy for electric shock, short circuit or even equipment damage accidents to be caused by accidental contact by operators, contact with metal foreign objects or humid environments.

[0004] Therefore, there are certain limitations in the power supply control of articulated arm scanners in the existing technology. Summary of the Invention

[0005] The purpose of this application is to address the shortcomings of the prior art by providing a power supply control system and a power supply control method to solve the practical problem of the limitations in power supply control for articulated arm scanners in the prior art.

[0006] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows: In a first aspect, embodiments of this application provide a power supply control system, the power supply control system comprising: a scanner assembly, an articulated arm assembly, a power supply control module, and a status detection module connected to the power supply control module, the power supply control module being connected to a power supply voltage, the status detection module being deployed in the articulated arm assembly, and the scanner assembly being detachably connected to the articulated arm assembly; The status detection module is used to determine whether to generate a power supply trigger signal based on the working status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly. If so, the status detection module is further configured to generate the power supply trigger signal and send the power supply trigger signal to the power supply control module; The power supply control module is used to supply power to the scanner component according to the power supply trigger signal and the power supply voltage.

[0007] As an optional implementation, the power supply control module includes: a delay submodule and a power supply control submodule, wherein the delay submodule is connected to the state detection module and the power supply control submodule, respectively; The delay submodule is used to receive the power supply trigger signal sent by the status detection module, perform delay processing on the power supply trigger signal to obtain the processed power supply trigger signal, and send the processed power supply trigger signal to the power supply control submodule; The power supply control submodule is used to output a power supply voltage to the scanner component according to the processed power supply trigger signal and the power supply voltage.

[0008] As an optional implementation, the power supply control system further includes: a filtering module; One end of the filtering module is used to connect to the power supply voltage, and the other end of the filter is connected to the power supply control submodule. The filtering module is used to filter the power supply voltage to obtain a filtered voltage, and then send the filtered voltage to the power supply control submodule.

[0009] As an optional implementation, the power supply control system further includes: an access connection module, which is connected to the power supply control submodule and the power interface of the scanner component respectively; The access connection module is used to send the power supply voltage output by the power supply control submodule to the power interface of the scanner component.

[0010] As an optional implementation, if the state detection module detects that the working state of the articulated arm assembly is "power-on" and the connection state between the scanner assembly and the articulated arm assembly is "connected", then it determines to generate the power supply trigger signal. If the status detection module detects that the working state of the articulated arm assembly is "power-on" and the connection state between the scanner assembly and the articulated arm assembly is "disconnected", then it determines that the power supply trigger signal will not be generated. If the status detection module detects that the articulated arm assembly is in a powered-off state, it determines that the power supply trigger signal will not be generated.

[0011] As an optional implementation, the state detection module generates a first level signal and uses the first level signal as the power supply trigger signal.

[0012] As an optional implementation, the state detection module is also used to determine whether to generate a power cut-off signal based on the working state of the articulated arm assembly and the connection state between the scanner assembly and the articulated arm assembly. If so, the status detection module is further configured to generate the power supply cut-off signal and send the power supply cut-off signal to the power supply control module; The power supply control module is also used to stop supplying power to the power interface of the scanner component according to the power supply cut-off signal.

[0013] As an optional implementation, if the state detection module detects that the working state of the articulated arm assembly changes from the power-on state to the power-off state or the connection state between the scanner assembly and the articulated arm assembly changes from the connected state to the disconnected state, then it determines to generate the power supply cut-off signal.

[0014] As an optional implementation, the state detection module generates a second level signal and uses the second level signal as the power supply cut-off signal.

[0015] Secondly, embodiments of this application provide a power supply control method, applied to the power supply control system described in the first aspect above, the method comprising: The status detection module determines whether to generate a power supply trigger signal based on the working status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly. If so, the status detection module generates the power supply trigger signal and sends the power supply trigger signal to the power supply control module; The power supply control module supplies power to the scanner component according to the power supply trigger signal and the power supply voltage.

[0016] The beneficial effects of this application are: This application provides a power supply control system and a power supply control method. The power supply control system includes an articulated arm assembly, a scanner assembly detachably connected to the articulated arm assembly, a status detection module deployed in the articulated arm assembly, and a power supply control module connected to the status detection module and connected to a power supply voltage. The status detection module detects the operating status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly. When it determines that the operating status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly meet preset power supply conditions, it generates a power supply trigger signal and sends the power supply trigger signal to the power supply control module. Triggered by the power supply trigger signal, the power supply control module safely supplies power to the scanner assembly reliably connected to the articulated arm assembly based on the connected power supply voltage. Because the power supply control module only supplies power to the scanner assembly when the status detection module detects that the operating status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly meet the preset power supply conditions, the power supply safety risks of the scanner assembly's power interface under no-load conditions are avoided, greatly improving the power supply safety of the scanner assembly.

Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] It should be noted that the term "comprising" will be used in the embodiments of this application to indicate the presence of the features declared thereafter, but does not exclude the addition of other features.

[0023] In 3D measurement and scanning equipment, articulated arm scanners are high-precision, portable measuring tools. Currently, once voltage is applied to the articulated arm scanner, regardless of whether the articulated arm is powered on or not, or whether the scanner components are actually connected to the articulated arm, the power interface at the scanner end is always energized. This poses a power supply safety hazard when the scanner end is unloaded, and is highly susceptible to electric shock, short circuits, or even equipment damage due to accidental contact by operators, contact with foreign metal objects, or humid environments. In other words, the current technology for power supply control of articulated arm scanners has certain limitations.

[0024] Based on the above-mentioned problems, this application provides a power supply control system in which the status detection module only triggers the power supply control module to supply power to the scanner component through a power supply trigger signal when it detects that the articulated arm assembly is in the powered-on state and the scanner component is reliably connected to the articulated arm assembly, thereby ensuring the safety of power supply to the scanner component.

[0025] Figure 1 Schematic diagram of the power supply control system provided in the embodiments of this application Figure 1 ,like Figure 1 As shown, the power supply control system includes: a scanner assembly 1, an articulated arm assembly 2, a power supply control module 3, and a status detection module 4 connected to the power supply control module 3. The power supply control module 3 is connected to a power supply voltage, and the status detection module 4 is deployed in the articulated arm assembly 2. The scanner assembly 1 and the articulated arm assembly 2 are detachably connected.

[0026] Optionally, refer to Figure 1 In the power supply control system, the scanner assembly 1 and the articulated arm assembly 2 are detachably connected. A status detection module 4 is deployed in the articulated arm assembly 2, and the status detection module 4 is connected to the power supply control module 3. The status detection module 4 detects the working status of the articulated arm assembly 2 and the connection status between the scanner assembly 1 and the articulated arm assembly 2. When the status detection result meets the preset power supply conditions, it sends a power supply trigger signal to the power supply control module 3, thereby triggering the power supply control module 3 to supply power to the scanner assembly 1 based on the access power voltage.

[0027] The status detection module 4 is used to determine whether to generate a power supply trigger signal based on the working status of the articulated arm assembly 2 and the connection status between the scanner assembly 1 and the articulated arm assembly 2.

[0028] Optionally, continue to refer to Figure 1 The articulated arm assembly 2 is independently powered, and the status detection module 4 is deployed in the articulated arm assembly 2. The power supply terminal of the status detection module 4 is connected to the power interface of the articulated arm assembly 2 to access the power supply voltage Vin.

[0029] The status detection module 4 monitors the working status of the articulated arm assembly 2 and the connection status between the scanner assembly 1 and the articulated arm assembly 2 in real time, and obtains the status detection results. The working status of the articulated arm assembly 2 includes power-on and power-off states, and the connection status between the scanner assembly 1 and the articulated arm assembly 2 includes connected and disconnected states. When the scanner assembly 1 is mechanically connected to the end of the articulated arm assembly 2 and a communication link is successfully established between the scanner assembly 1 and the articulated arm assembly 2, the connection status is connected. When the scanner assembly 1 is detached from the end of the articulated arm assembly 2, the connection status is disconnected.

[0030] Specifically, the status detection module 4 can detect the operating status of the articulated arm assembly 2 by measuring the power-on signal level of the articulated arm assembly 2, and detect the connection status between the scanner assembly 1 and the articulated arm assembly 2 by measuring the level of the pins connected to the articulated arm assembly 2 and the handshake success indicator of the communication link between the articulated arm assembly 2 and the scanner assembly 1, thus obtaining the status detection result. The status detection result is used to indicate whether the articulated arm assembly 2 is powered on and running normally and whether the scanner assembly 1 is reliably connected to the articulated arm assembly 2.

[0031] The status detection module 4 determines whether the preset power supply conditions are met based on the status detection results, so as to determine whether to generate a power supply trigger signal.

[0032] If so, the status detection module 4 is also used to generate a power supply trigger signal and send the power supply trigger signal to the power supply control module 3.

[0033] Optionally, if the status detection module 4 determines that the status detection result meets the preset power supply conditions, it generates a power supply trigger signal and sends the power supply trigger signal to the power supply control module 3 so as to trigger the power supply control module 3 to supply power to the scanner component 1 through the power supply trigger signal.

[0034] Continue to refer to Figure 1 In other words, when the status detection module 4 determines that the status detection result meets the preset power supply conditions, it sends a power supply trigger signal to the power supply control module 3 so that the power supply control module 3 outputs a power supply voltage Vout to the scanner component 1 under the trigger of the power supply trigger signal.

[0035] The power supply control module 3 is used to supply power to the scanner component 1 according to the power supply trigger signal and the power supply voltage.

[0036] Optionally, the power supply control module 3 supplies power to the scanner component 1 based on the access power supply voltage Vin when triggered by the power supply trigger signal.

[0037] Continue to refer to Figure 1The power interface of the scanner assembly 1 is connected to the output terminal of the power supply control module 3. Based on the input power supply voltage Vin, the power supply control module 3 outputs the power supply voltage Vout to the power interface of the scanner assembly through the output terminal to safely supply power to the scanner assembly 1 which is reliably connected to the articulated arm assembly 2.

[0038] For example, both the power supply voltage Vin and the supply voltage Vout are 24V DC voltage.

[0039] In this embodiment, the power supply control system includes an articulated arm assembly, a scanner assembly detachably connected to the articulated arm assembly, a status detection module deployed in the articulated arm assembly, and a power supply control module connected to the status detection module and connected to a power supply voltage. The status detection module detects the operating status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly. When it determines that the operating status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly meet preset power supply conditions, it generates a power supply trigger signal and sends the power supply trigger signal to the power supply control module. Triggered by the power supply trigger signal, the power supply control module safely supplies power to the scanner assembly reliably connected to the articulated arm assembly based on the connected power supply voltage. Because the power supply control module only supplies power to the scanner assembly when the status detection module detects that the operating status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly meet the preset power supply conditions, the power supply safety risks of the scanner assembly's power interface under no-load conditions are avoided, greatly improving the power supply safety of the scanner assembly.

[0040] Figure 2 Schematic diagram of the power supply control system provided in the embodiments of this application Figure 2 ,like Figure 2 As shown, the power supply control module 3 includes a delay submodule 31 and a power supply control submodule 32. The delay submodule 31 is connected to the status detection module 4 and the power supply control submodule 32, respectively.

[0041] Optionally, refer to Figure 2 The input terminal of the delay submodule 31 in the power supply control module 3 is connected to the status detection module 4, and the output terminal is connected to the power supply control submodule 32. The power supply trigger signal output by the status detection module 4 is delayed and then output to the power supply control submodule 32 to prevent the power supply control submodule 32 from being impacted by transient current.

[0042] The delay submodule 31 is used to receive the power supply trigger signal sent by the status detection module 4, perform delay processing on the power supply trigger signal to obtain the processed power supply trigger signal, and send the processed power supply trigger signal to the power supply control submodule 32.

[0043] Optionally, continue to refer to Figure 2The delay submodule 31 receives the power supply trigger signal from the status detection module 4, performs delay processing on the power supply trigger signal, for example, delays the power supply trigger signal by 170ms to obtain the processed power supply trigger signal, and sends the processed power supply trigger signal to the power supply control submodule 32.

[0044] For example, the delay submodule 31 may include an RC delay circuit. In the RC delay circuit, the gate voltage of the P-channel metal-oxide-semiconductor field-effect transistor (MOS) is slowly controlled by adjusting the resistance value of the resistor and the capacitance value of the capacitor. The processed power supply trigger signal is output to the power supply control submodule 32 through the drain of the PMOS transistor, which can realize the slow conduction of the power supply control submodule 32, suppress the power-on inrush current of the power supply control submodule 32, and protect the power supply control submodule 32.

[0045] The power supply control submodule 32 is used to output a power supply voltage to the scanner assembly 1 based on the processed power supply trigger signal and the power supply voltage.

[0046] Optionally, continue to refer to Figure 2 After being triggered by the processed power supply trigger signal, the power supply control submodule 32 slowly turns on and outputs the power supply voltage Vout to the power interface of the scanner assembly 1 based on the accessed power supply voltage Vin, so as to safely supply power to the scanner assembly 1 which is reliably connected to the articulated arm assembly 2.

[0047] Since the power supply control submodule 32 starts slowly under the trigger of the processed power supply trigger signal, the impact of the power-on inrush current on the power supply control submodule 32 is avoided, which greatly improves the protection of the power supply control submodule 32.

[0048] For example, the power supply control submodule 32 may include a voltage divider resistor and a solid-state relay. The voltage divider resistor divides the processed power supply trigger signal to trigger the solid-state relay to conduct. After the solid-state relay conducts, it outputs a power supply voltage Vout to the power interface of the scanner component 1. The solid-state relay is composed of an optocoupler and an NMOS transistor.

[0049] In this embodiment, the power supply control module includes a delay submodule and a power supply control submodule. The input of the delay submodule is connected to the status detection module, and the output is connected to the power supply control submodule. The delay submodule receives a power supply trigger signal from the status detection module, performs a delay processing on the power supply trigger signal, and then sends it to the power supply control submodule. Upon triggering by the processed power supply trigger signal, the power supply control submodule slowly turns on and outputs a power supply voltage to the power interface of the scanner component based on the connected power supply voltage, thereby safely supplying power to the scanner component reliably connected to the articulated arm component. By delaying the power supply trigger signal through the delay submodule, the impact of the power-on inrush current on the power supply control submodule is avoided, greatly improving the protection of the power supply control submodule.

[0050] As an optional implementation, the power supply control system also includes: a filter module 5.

[0051] One end of the filter module 5 is used to connect to the power supply voltage, and the other end of the filter is connected to the power supply control submodule 32.

[0052] Optionally, continue to refer to Figure 2 In the power supply control system, the input terminal of the filter module 5 is connected to the power supply voltage Vin, and the output terminal of the filter module 5 is connected to the power supply terminal of the power supply control submodule 32 to provide the power supply control submodule 32 with a stable voltage after filtering.

[0053] The filtering module 5 is used to filter the power supply voltage to obtain the filtered voltage, and then send the filtered voltage to the power supply control submodule 32.

[0054] Optionally, continue to refer to Figure 2 The filtering module 5 filters the input power supply voltage Vin, removing high-frequency and low-frequency noise to obtain a stable voltage after filtering, and outputs the stable voltage after filtering to the power supply control submodule 32.

[0055] For example, the filtering module 5 may include a first filtering capacitor, a second filtering capacitor, and a transient suppression diode. The first filtering capacitor may have a capacitance of 4.7uF and is used to filter out low-frequency noise; the second filtering capacitor may have a capacitance of 0.1uF and is used to filter out high-frequency noise; the transient suppression diode is used to conduct discharge current when a surge occurs in the connected power supply voltage Vin (e.g., exceeding the 24V clamping value), preventing overvoltage damage to the power supply control submodule 32 and providing overvoltage protection for the power supply control submodule 32.

[0056] In this embodiment, the power supply control system also includes a filtering module. One end of the filtering module is connected to the power supply voltage, and the other end is connected to the power supply control submodule. The filtering module filters the power supply voltage, removing high-frequency and low-frequency noise to obtain a filtered voltage, which is then sent to the power supply control submodule. This provides a stable filtered voltage to the power supply control submodule and provides overvoltage protection to prevent damage to the submodule due to overvoltage.

[0057] As an optional implementation, the power supply control system further includes an access connection module 6, which is connected to the power supply control submodule 32 and the power interface of the scanner assembly 1.

[0058] Optionally, continue to refer to Figure 2 The power supply control system also includes an access connection module 6 that is connected to the power interface of the power supply control submodule 32 and the scanner component 1 respectively. The access connection module 6 realizes the reliability of the power supply path between the power interface of the power supply control submodule 32 and the scanner component 1 through the built-in adapter interface.

[0059] The connection module 6 is used to send the power supply voltage output by the power supply control submodule 32 to the power interface of the scanner component 1.

[0060] Optionally, continue to refer to Figure 2 The input terminal of the connection module 6 is connected to the output terminal of the power supply control submodule 32 to receive the power supply voltage Vout output by the power supply control submodule 32. The output terminal of the connection module 6 is connected to the power interface of the scanner assembly 1 to transmit the power supply voltage Vout output by the power supply control submodule 32 to the power interface of the scanner assembly 1.

[0061] In this embodiment, the power supply control system further includes an access connection module connected to the power interfaces of both the power supply control submodule and the scanner component. The access connection module receives the power supply voltage output by the power supply control submodule and transmits it to the power interface of the scanner component via a built-in adapter interface. This access connection module ensures the reliability of the power supply path between the power interfaces of the power supply control submodule and the scanner component.

[0062] As an optional implementation, if the status detection module 4 detects that the working state of the articulated arm assembly 2 is the power-on state and the connection state between the scanner assembly 1 and the articulated arm assembly 2 is the access state, then it determines to generate a power supply trigger signal.

[0063] Optionally, when the status detection module 4 detects that the working state of the articulated arm assembly 2 is the power-on state and the connection state between the scanner assembly 1 and the articulated arm assembly 2 is the access state, it determines that the preset power supply conditions are met and can generate a power supply trigger signal to trigger the power supply control module 3 to supply power to the scanner assembly 1, ensuring that power supply to the scanner assembly 1 only occurs when the articulated arm assembly 2 and the scanner assembly 1 are ready and reliably connected to each other.

[0064] The preset power supply conditions are that the articulated arm assembly 2 is running normally and the scanner assembly 1 is reliably connected to the articulated arm assembly 2.

[0065] For example, if the status detection module 4 detects that the power-on signal of the articulated arm assembly 2 is at an effective level, the level of the plug-in pin in the articulated arm assembly 2 is at an effective level, and there is a handshake success indicator for the communication link between the articulated arm assembly 2 and the scanner assembly 1, it indicates that the articulated arm assembly 2 is powered on and running normally and the scanner assembly 1 is reliably connected to the articulated arm assembly 2, that is, the preset power supply conditions are met.

[0066] If the status detection module 4 detects that the articulated arm assembly 2 is in the powered-on state and the connection between the scanner assembly 1 and the articulated arm assembly 2 is disconnected, then it determines that no power supply trigger signal will be generated.

[0067] Optionally, when the status detection module 4 detects that the working state of the articulated arm assembly 2 is powered on and the connection state between the scanner assembly 1 and the articulated arm assembly 2 is disconnected, it determines that the preset power supply conditions are not met. In this case, it does not generate a power supply trigger signal to trigger the power supply control module 3 to supply power to the scanner assembly 1. This ensures that in the scenario where the articulated arm assembly 2 is ready but the scanner assembly 1 is not ready or the scanner assembly 1 is not reliably connected to the articulated arm assembly 2, the power supply control module 3 does not supply power to the scanner assembly 1, thus protecting the power interface of the scanner assembly 1.

[0068] For example, if the status detection module 4 detects that the power-on signal of the articulated arm assembly 2 is at a valid level and the level of the plug-in pin in the articulated arm assembly 2 is at an invalid level, or if the status detection module 4 detects that the power-on signal of the articulated arm assembly 2 is at a valid level, the level of the plug-in pin in the articulated arm assembly 2 is at a valid level and there is no handshake success indicator for the communication link between the articulated arm assembly 2 and the scanner assembly 1, it indicates that the articulated arm assembly 2 is powered on and running normally, but the scanner assembly 1 is not reliably connected to the articulated arm assembly 2, that is, the preset power supply conditions are not met.

[0069] If the status detection module 4 detects that the working state of the articulated arm assembly 2 is the off state, it determines that no power supply trigger signal will be generated.

[0070] Optionally, when the status detection module 4 detects that the working state of the articulated arm assembly 2 is the off state, it is not necessary to detect the connection state between the scanner assembly 1 and the articulated arm assembly 2. It directly determines that the preset power supply conditions are not met and does not generate a power supply trigger signal to trigger the power supply control module 3 to supply power to the scanner assembly 1. This ensures that in the scenario where the articulated arm assembly 2 is not ready, the power supply control module 3 will not supply power to the scanner assembly 1 regardless of whether the scanner assembly 1 is reliably connected to the articulated arm assembly 2, thus protecting the power interface of the scanner assembly 1.

[0071] For example, if the status detection module 4 detects that the power-on signal of the articulated arm assembly 2 is at an invalid level, it indicates that the articulated arm assembly 2 is in a power-off state, i.e., the preset power supply conditions are not met. Regardless of whether the scanner assembly 1 is reliably connected, as long as the articulated arm assembly 2 is in a power-off state, the status detection module 4 will not generate a power supply trigger signal, cutting off the possibility of power supply to the scanner assembly 1 in a non-working state from the source, and completely avoiding the risk of electric shock to the user from contacting a live power interface during the disassembly and assembly of the scanner assembly 1.

[0072] In this embodiment, the state detection module determines to generate a power supply trigger signal when it detects that the articulated arm assembly is in the powered-on state and the scanner assembly and the articulated arm assembly are in the connected state. When it detects that the articulated arm assembly is in the powered-on state and the scanner assembly and the articulated arm assembly are in the disconnected state, or the articulated arm assembly is in the powered-off state, it determines not to generate a power supply trigger signal. This ensures that power is supplied to the scanner assembly only when the articulated arm assembly and the scanner assembly are ready and reliably connected, protecting the scanner assembly's power interface and completely avoiding the risk of electric shock to the user from contacting a live power interface during scanner assembly or disassembly.

[0073] As an optional implementation, the state detection module 4 generates a first level signal and uses the first level signal as a power supply trigger signal.

[0074] Optionally, when the status detection module 4 detects that the working state of the articulated arm assembly 2 is the power-on state and the connection state between the scanner assembly 1 and the articulated arm assembly 2 is the access state, it generates a first level signal and outputs the first level signal as a power supply trigger signal to the power supply control module, so as to trigger the power supply control module to conduct and supply power to the scanner assembly 1.

[0075] For example, the first level signal can be a 15V high-level signal, which triggers the solid-state relay in the electronic control module to turn on and supply power to the scanner assembly 1.

[0076] In this embodiment, the status detection module generates a first level signal and outputs the first level signal as a power supply trigger signal to the power supply control module, so as to trigger the power supply control module to turn on and supply power to the scanner component.

[0077] As an optional implementation, the status detection module 4 is also used to determine whether to generate a power supply cut-off signal based on the working status of the articulated arm assembly 2 and the connection status between the scanner assembly 1 and the articulated arm assembly 2.

[0078] Optionally, when the power supply control module 3 stably supplies power to the scanner assembly 1, the status detection module 4 also detects in real time whether the working status of the articulated arm assembly 2 or the connection status between the scanner assembly 1 and the articulated arm assembly 2 has changed, and determines whether the preset power-off conditions are met, so as to determine whether to generate a power supply cut-off signal.

[0079] The power supply cut-off signal is used to trigger the power supply control module 3 to stop supplying power to the scanner component 1.

[0080] If so, the status detection module 4 is also used to generate a power supply cut-off signal and send the power supply cut-off signal to the power supply control module 3.

[0081] Optionally, if the status detection module 4 determines that the preset power-off condition is met, it generates a power supply cut-off signal and sends the power supply cut-off signal to the power supply control module 3, so as to trigger the power supply control module 3 to stop supplying power to the scanner component 1 through the power supply cut-off signal.

[0082] Continue to refer to Figure 1 and Figure 2 In other words, when the status detection module 4 determines that the preset power-off condition is met, it sends a power cut-off signal to the power supply control module 3 so that the power supply control module 3 stops outputting the power supply voltage Vout to the scanner component 1 under the trigger of the power cut-off signal.

[0083] The power supply control module 3 is also used to stop supplying power to the power interface of the scanner component 1 according to the power supply cut-off signal.

[0084] Optionally, the power supply control module 3 stops supplying power to the power interface of the scanner component 1 upon triggering a power supply cutoff signal. Specifically, the delay submodule 31 receives the power supply cutoff signal from the status detection module 4, performs a delay processing on the signal, and sends the processed power supply cutoff signal to the power supply control submodule 32. This causes the solid-state relay in the power supply control submodule 32 to slowly turn off upon triggering the processed power supply cutoff signal, thus protecting the power supply control submodule 32.

[0085] After being triggered by the processed power cut-off signal, the power supply control submodule 32 slowly shuts down and stops supplying power to the power interface of the scanner component 1, thereby preventing damage to the power interface of the scanner component 1.

[0086] In this embodiment, the status detection module detects the working status of the articulated arm assembly and the connection status between the scanner assembly and the articulated arm assembly. When it determines that the preset power-off conditions are met, it generates a power supply cut-off signal and sends the signal to the power supply control module. Triggered by the power supply cut-off signal, the power supply control module stops supplying power to the scanner assembly's power interface. This avoids the potential safety hazards of power supply to the scanner assembly's power interface when the scanner assembly is not reliably connected to the articulated arm assembly or when the articulated arm assembly is not powered on, greatly improving the power supply safety of the scanner assembly's power interface.

[0087] As an optional implementation, if the status detection module 4 detects that the working state of the articulated arm assembly 2 changes from the power-on state to the power-off state or the connection state between the scanner assembly 1 and the articulated arm assembly 2 changes from the connected state to the disconnected state, then it determines to generate a power supply cut-off signal.

[0088] Optionally, when the status detection module 4 detects that the working state of the articulated arm assembly 2 changes from the power-on state to the power-off state, or when the status detection module 4 detects that the connection state between the scanner assembly 1 and the articulated arm assembly 2 changes from the connected state to the disconnected state, it indicates that the articulated arm assembly 2 is powered off or the scanner assembly 1 is detached from the articulated arm assembly 2. At this time, the preset power-off condition is met, and the status detection module 4 determines to generate a power supply cut-off signal.

[0089] In scenarios where the articulated arm assembly 2 is powered off or the scanner assembly 1 is detached from the articulated arm assembly 2, the power supply cut-off signal can ensure that the power supply control module 3 stops supplying power to the power interface of the scanner assembly 1, thereby preventing the power interface of the scanner assembly 1 from being energized in scenarios where the articulated arm assembly 2 is powered off or the scanner assembly 1 is detached from the articulated arm assembly 2.

[0090] In this embodiment, when the status detection module detects that the working state of the articulated arm assembly changes from the power-on state to the power-off state, or when the status detection module detects that the connection state between the scanner assembly and the articulated arm assembly changes from the connected state to the disconnected state, the status detection module determines to generate a power supply cut-off signal. This ensures that, in scenarios where the articulated arm assembly is powered off or the scanner assembly is detached from the articulated arm assembly, the power supply cut-off signal ensures that the power control module stops supplying power to the power interface of the scanner assembly, preventing the scanner assembly's power interface from being energized in these scenarios.

[0091] As an optional implementation, the status detection module 4 generates a second level signal and uses the second level signal as a power supply cut-off signal.

[0092] Optionally, when the status detection module 4 detects that the working state of the articulated arm assembly 2 changes from the power-on state to the power-off state or the connection state between the scanner assembly 1 and the articulated arm assembly 2 changes from the connected state to the disconnected state, the status detection module 4 generates a second level signal and outputs the second level signal as a power supply cut-off signal to the power supply control module, so as to trigger the power supply control module to shut down and stop supplying power to the power interface of the scanner assembly 1 through the power supply cut-off signal.

[0093] For example, the second level signal can be a low-level signal of 0V, which triggers the solid-state relay in the electronic control module to turn off and stop supplying power to the power interface of the scanner component 1.

[0094] In this embodiment, the status detection module generates a second level signal and outputs the second level signal as a power supply cutoff signal to the power supply control module, so as to trigger the power supply control module to shut down and stop supplying power to the power interface of the scanner component.

[0095] Based on the same inventive concept, this application also provides a power supply control method corresponding to the power supply control system.

[0098] The power supply control module supplies power to the scanner components based on the power supply trigger signal and the power supply voltage.

[0099] As an optional implementation, if the status detection module detects that the articulated arm assembly is in the power-on state and the scanner assembly is in the connected state, then it determines to generate a power supply trigger signal.

[0100] If the status detection module detects that the articulated arm assembly is in the powered-on state and the connection between the scanner assembly and the articulated arm assembly is disconnected, it determines that no power supply trigger signal will be generated.

[0101] If the status detection module detects that the articulated arm assembly is in a powered-off state, it determines that no power supply trigger signal will be generated.

[0102] As an optional implementation, the state detection module generates a first level signal and uses the first level signal as a power supply trigger signal.

[0105] The power supply control module stops supplying power to the power interface of the scanner component based on the power supply cut-off signal.

[0106] As an optional implementation, if the status detection module detects that the working state of the articulated arm assembly changes from the power-on state to the power-off state or the connection state between the scanner assembly and the articulated arm assembly changes from the connected state to the disconnected state, then it determines to generate a power supply cut-off signal.

[0107] As an optional implementation, the status detection module generates a second level signal and uses the second level signal as a power supply cut-off signal.
