Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a device start control system and method and a mobile medical device. BACKGROUND

[0002] In the prior art, medical devices such as large imaging devices, operating tables or mobile workstations are often equipped with electrically driven brake systems, which are essentially a kind of brake device driven by electricity, usually integrated in the casters or moving mechanism of the device. The main function of the electrically driven brake is to ensure that the medical device can be fixed at a position where stable work is required, preventing the device from moving accidentally during the examination or treatment process and affecting the operation accuracy or safety, while the brake can be conveniently released to realize flexible movement when the device needs to be transported.

[0003] Generally, in order to simplify the design and wiring, the electrically driven brake shares the same power supply system with the main machine of the medical device. When the device is connected to an external power supply and powered on, the electrically driven brake is usually in a released state, allowing the device to move freely for position adjustment. In the unpowered state, the electrically driven brake is generally in a braking state, locking the device in place to prevent the device from sliding due to accidental power failure. However, this brings obvious inconvenience: if the medical device is not connected to a power supply, for example, during device initialization and installation, temporary position adjustment or power failure, the electrically driven brake will always remain in a braking state when unpowered, making the device unable to move and relying on additional manpower or redundant mechanical structures to release the brake, which not only increases the operation burden in emergency clinical scenarios or daily maintenance, but also may delay the medical process. SUMMARY

[0004] To solve the above technical problems, the present application discloses a device start control system, method and mobile medical device, which enables the mobile medical device to control the electrically driven brake to move in the on-site state by using a backup power supply and a power supply control board, thereby improving the mobility of the device without external power supply under the premise of ensuring safe braking.

[0005] Specifically, the technical solution of the present application is as follows: In a first aspect, the present application discloses a device start control system applied to a mobile medical device, which comprises a power supply control board and an electrically driven brake control module. The power supply control board has a dual power supply input interface, including a network power supply input interface and a backup power supply input interface; in response to a start signal, the power supply control board is used to judge whether the device is connected to a network power supply. If the network power supply is not connected, after receiving the start signal, the device enters an on-site state and counts time; at this time, the power supply control board is configured to start the backup power supply to supply power to the electrically driven brake control module.

[0006] In some embodiments, the power control board is further configured to: determine whether the electric parking brake control module receives an operation instruction within a preset machine-on time threshold; if the operation instruction is not received, stop supplying power to the electric parking brake control module after the machine-on time threshold ends, and the device exits the machine-on state.

[0007] In some embodiments, the control system further comprises a network power isolation transformer for isolating the network power supply and the power control board. The network power isolation transformer is also connected to the backup power supply, for providing isolated AC input to the backup power supply when the network power supply is normal, so as to charge the backup power supply.

[0008] In some embodiments, the control system further comprises a system main control board and a radiation source control module, which are respectively connected to the power control board.

[0009] In some embodiments, the power control board is further configured to: if it is determined that the device is connected to the network power supply, the device enters a normal start state; at this time, the network power supply is started to supply power to the device as a whole, which includes the system main control board, the radiation source control module and the electric parking brake control module.

[0010] In some embodiments, after the device is started, the power control board is further configured to monitor the power supply state of the network power supply. In the normal start state, if the network power supply connection is disconnected, the backup power supply is started to supply power to the system main control board, and the radiation source control module is refused to perform exposure operation; so that after the network power supply is reconnected, the device can restore the working state before power failure.

[0011] In some embodiments, the control system further comprises an indicator light for indicating whether the device is in a machine-on state or a normal start state.

[0012] In a second aspect, the application also discloses a device start control method, which is suitable for the device start control system in any one of the above embodiments, and the method comprises the following steps: in response to a start signal, determining whether the device is connected to a network power supply through the power control board; if the device is connected to the network power supply, the device enters a normal start state; at this time, the network power supply is started to supply power to the device as a whole; If the network power is not connected, the device enters the standby state and counts time after receiving the start signal. At this time, the backup power supply starts to supply power to the electric parking brake control module; Within the preset standby time threshold, it is judged whether the electric parking brake control module receives an operation instruction; If the operation instruction is not received, the power supply to the electric parking brake control module is stopped after the standby time threshold ends, and the device exits the standby state; If the operation instruction is received within the standby time threshold, the device is restarted after the operation instruction is executed.

[0013] In some embodiments, the control method further comprises: After the device is normally started, the power supply state of the network power supply is monitored by the power control board; In the normal start state, if the network power supply connection is disconnected, the backup power supply starts to supply power to the system main control board, and the X-ray source control module is refused to perform exposure operation; so that after the network power supply is reconnected, the device can restore the working state before the power failure.

[0014] In a third aspect, the application also discloses a mobile medical device comprising the device start control system according to any one of the preceding embodiments.

[0015] Compared with the prior art, the application has at least one of the following beneficial effects: 1. The present application cooperates the power control board and the backup power supply, so that when the device is not connected to the network power supply, the system enters the standby state of maintaining only the electric parking brake control power supply, and the user can still freely control the device braking or release through the original electric parking brake system without additional mechanical assistance, which significantly reduces the operation difficulty of non-fixed personnel and improves the efficiency of device scheduling and positioning.

[0016] 2. The application uses the bypass and battery power intelligent switching mechanism of the backup power supply to automatically switch to the battery power mode when the network power supply is interrupted, so that the system main control board will not lose data due to power failure. After the network power supply is restored, the system can instantly switch back to bypass power supply and immediately restore to the working state before the power failure, realizing seamless maintenance and instantaneous recovery of the system working state under power failure.

[0017] 3. The application integrates a single backup power supply and an intelligent power control board to meet the requirements of electric parking brake control and system continuous operation with a simple electrical architecture, avoiding redundant mechanical components and reducing the requirements for power supply power and volume, making the overall system lighter and easier to deploy and maintain in mobile medical devices.

[0024] It should be noted that, in this text, unless otherwise specifically defined and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection. It can be mechanical connection, or electrical connection. It can be direct connection, or indirect connection through intermediate medium. It can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0027] With the increasing demand for flexibility and space utilization in modern medical scenarios, mobile medical equipment such as portable ultrasound instruments, digital X-ray machines, and multifunctional monitoring workstations has become increasingly popular. These devices are generally equipped with advanced electric brakes. Compared with traditional mechanical brakes, electric brakes can provide faster and more uniform brake force distribution by integrating sensors and motor drives, significantly improving the braking stability and safety of the device under different ground conditions. In particular, on uneven or slippery ground, the device can effectively prevent sliding or shaking, thereby ensuring the stability of precise examination and treatment.

[0028] However, this highly dependent brake system also has technical defects: its control logic is usually deeply bound with the main power supply of the device. When the device is started for normal use with an external network power supply, the electric brake can be conveniently released and locked through the operation panel or remote control. However, once the network power supply is not connected, the device cannot be started normally, at which time the electric brake system defaults to a safe braking state and is locked. The existing technical solutions usually choose to release the electric brake through a mechanically designed release mechanism, but this increases the difficulty of use for mobile devices that are not used by fixed professionals, and may also cause potential damage to the device structure or brake system.

[0029] In addition, in some prior art, in order to avoid the disconnection of the network power supply during the operation, the workstation and display device of the medical instrument are powered off, thereby causing the operation to be forced to be interrupted due to the sudden stop of the device. Therefore, the relevant technical personnel select to use an uninterruptible power supply (UPS) as a buffer to ensure continuous power supply. However, due to the large volume and weight of the high-power online uninterruptible power supply, it is difficult to integrate into a mobile device. Therefore, the backup power supply of this type of device does not support power supply to the whole machine, but only provides power supply buffering for the core computing unit and display of the device to ensure that data is not lost and display is not interrupted. The power supply range does not consider the electric brake load. This type of technology cannot solve the technical problem that the device is completely locked and cannot be moved due to the disconnection of the electric brake. It can be seen that in the clinical scene of needing to urgently adjust the position of the device, quickly transport the patient, or move the device for maintenance after power failure, the existing technology causes significant inconvenience and operation risk.

[0030] Therefore, how to solve the mobility problem of the electric brake in the unconnected state while maintaining the excellent stability performance of the electric brake has become a technical challenge to improve the practicality and user experience of the mobile medical instrument. Based on the above technical content, the present application provides a device start control system applied to a mobile medical device. Referring to the accompanying drawings Figure 1 The device start control system of the present application has one embodiment as follows.

[0031] The control system comprises a power control board and an electric brake control module.

[0032] The power control board has a dual-power input interface, including a network power input interface and a backup power input interface. In response to a start signal, the power control board is used to determine whether the device is connected to the network power supply.

[0033] If the network power supply is not connected, after receiving the start signal, the device enters the resident state and counts the time. At this time, the power control board is configured to start the backup power supply to supply power to the electric brake control module.

[0034] Specifically, the power control board of the present application is designed with a dual-power input interface, which is connected to the network power Net Power and the backup power UPS, respectively. The electric brake control module is connected to the power output interface of the power interconnection board (PIB). After receiving the start signal, the PIB first detects whether the network power supply is connected.

[0035] In some embodiments, the system comprises a standby state and a normal start state. If the PIB detects that the network power is not connected, the device enters the standby state and starts timing, at which time the power control board starts the UPS, but only powers the electric brake control module to the rear end, ensuring that the electric brake can still be normally braked and released by the user through the foot pedal or button. This process does not require mechanical auxiliary devices and is completely realized by electrical logic, which not only maintains the mobility of the device during power failure, but also avoids the rapid depletion of the backup power supply caused by the power supply of the whole machine.

[0036] Compared with the prior art, the present application innovates the "standby state" of the device, which has the advantages that by combining software and hardware, the device state and power supply strategy are bound, and under the premise of ensuring the mobility of the electric brake of the device and the continuous availability of brake control, the system structure is significantly simplified, the redundant mechanical release mechanism is cancelled, the user operation complexity and device maintenance cost are reduced, the sustainable power supply time of the backup power supply in critical scenarios is prolonged, and the practicality and reliability of the mobile medical device in a non-external power environment are improved.

[0037] In other embodiments, the control system further comprises an indicator light for indicating whether the device is in a standby state or a normal start state. Optionally, when the network power is not plugged in, the system is in a standby state, at which time the start indicator light is in a breathing state.

[0038] On the basis of the above-mentioned embodiments, another embodiment of a device start control system is disclosed, and the power control board is further used for: Within a preset standby time threshold, it is judged whether the electric brake control module receives an operation instruction.

[0039] If the operation instruction is not received, after the end of the standby time threshold, the power supply to the electric brake control module is stopped, and the device exits the standby state.

[0040] Specifically, when the device enters the standby state, an internal timer is started, and it is continuously monitored within a preset standby time threshold whether the electric brake control module receives a brake or release operation instruction issued by the user.

[0041] If no operation signal is detected within the entire threshold time, the PIB judges that the device is in a non-use state, and then automatically cuts off the power supply enable signal to the backup power supply, thereby stopping the power supply to the electric brake control module, making the device completely power off and exit the standby state.

[0042] This application's power control board achieves intelligent standby status management through internally integrated timing and control logic. This effectively prevents the device from remaining in a low-power standby state for extended periods due to user forgetfulness or temporary absence, thus preventing unnecessary consumption or even over-discharge damage of backup power and improving the reliability and lifespan of the power system.

[0043] Optionally, the preset dwell time threshold is 1 minute.

[0044] This application provides another embodiment of a device startup control system. Based on any of the above embodiments, the control system further includes: a grid power isolation transformer for isolating the grid power supply from the power control board.

[0045] The grid power isolation transformer is also connected to the backup power supply, and is used to provide isolated AC input to the backup power supply when the grid power supply is normal, so as to charge the backup power supply.

[0046] For details, please refer to the attached instruction manual. Figure 1 As shown, the grid power isolation transformer of this application is connected in series between the grid power input (NetPower) and the equipment power control board (PIB). Through its internal structure, it completely isolates the grid power supply from the equipment circuitry, ensuring personnel safety. Simultaneously, the output of the grid power isolation transformer is designed to be split into two: one path directly connects to the grid power input interface of the PIB, forming the main power supply path. The other path connects to the input of the standby uninterruptible power supply (UPS), electrically forming a UPS power bypass. This allows power to supply the entire system directly through this transformer without passing through the UPS inverter stage when the grid power supply is normal.

[0047] Meanwhile, the power isolation transformer also serves as the energy source for the UPS under normal operating conditions, providing isolated and filtered power input to its internal energy storage unit to maintain charging.

[0048] This application provides another embodiment of a device start-up control system. Based on any of the above embodiments, the control system further includes: a system main control board and a radiation source control module, which are respectively connected to the power control board.

[0049] Specifically, the main control board (MCB) and the X-ray source control module are the core functional units, and are connected to the power output interface of the PIB through an electrical interface.

[0050] The system main control board (MCB) serves as the central processing and scheduling center for the entire device. It is responsible for running the operating system, image processing software, and human-machine interface, and for receiving real-time power status signals from the power control board. Once the power control board determines that the system can start normally, the system main control board is awakened and loads the complete working environment, while simultaneously taking over the scheduling of subsystems such as the X-ray source control module.

[0051] The Xray source control module is specifically responsible for the precise control of the X-ray source, including setting exposure parameters, generating and controlling high voltage, and ensuring safety interlock protection during the exposure process.

[0052] In some embodiments, the power control board is further configured to: If it is determined that the device is connected to the mains power supply, the device enters the normal startup state. At this time, the mains power supply is activated to supply power to the entire device.

[0053] The complete device includes the system main control board, the radiation source control module, and the electric ground brake control module.

[0054] Specifically, under normal power supply mode, each module connected to the PIB power output interface obtains sufficient power through the mains power supply (UPS bypass) to support high-performance computing and high-power exposure.

[0055] In other embodiments, after the device is started, the power control board is also used to monitor the power supply status of the grid power supply.

[0056] In normal power-on mode, if the mains power connection is disconnected, the backup power supply will be activated to power the system main control board, while the X-ray source control module will be prevented from performing exposure operations. This ensures that once the mains power is reconnected, the equipment can immediately and completely restore its operating state before the power outage.

[0057] Optionally, the UPS includes a voltage comparison-based switching circuit. When an abnormality in the input power supply (including power outage or low voltage) is detected, the internal circuitry of the UPS automatically switches the power supply to the output load from the UPS bypass channel to the UPS battery. This switching action is entirely autonomous, allowing the system to be powered via the UPS bypass when the power supply is normal, and automatically switching to the UPS battery to maintain critical operating conditions when the power supply is abnormal.

[0058] In some optional implementations, the PIB continuously monitors the input power status. When it detects a switch from stable grid power (UPS bypass) to UPS battery power, it makes system-level control decisions based on a preset program. Optionally, the UPS only maintains power to core systems such as computers, monitors, and control circuits to maintain data and operational status. Because battery capacity is limited, it cannot support high-power loads. Therefore, high-power operations, such as exposure operations, are prohibited.

[0059] Optionally, when the mains power is interrupted and the system is powered by a backup power supply, the PIB can choose to simultaneously limit the power supply to both modules, maintaining only a minimum state or completely cutting off power to prevent the backup power from being depleted too quickly. In this case, the X-ray source control module is still prohibited from performing exposure operations, while the system main control board may be in a sleep state.

[0060] In some alternative implementations, when an abnormality in the input network power supply is detected, an alarm signal is emitted by an indicator light to alert the user that the network power supply is abnormal or that the equipment has switched power supplies, so that relevant technicians can check the network power connection in a timely manner.

[0061] Based on the above embodiments, the system main control board (MCB) is also configured with a built-in power outage standby timer. When the system detects a grid power outage and switches to a standby state powered by a backup power source, the timer is started and continuously polls the grid power recovery status within a preset power outage standby duration.

[0062] If no power reconnection is detected after the preset time has elapsed, the main control board will automatically send sequential shutdown commands to the operating system and all critical application software running on it, triggering a standard system-level shutdown process to gradually save data and shut down services and programs. During the shutdown process, the main control board monitors the operating system status signals and feedback from the power control board to confirm whether the system has completed a normal shutdown.

[0063] If a normal shutdown is confirmed, the main control board will send a final power-down command to the power control board, sequentially cutting off the output of the workstation, auxiliary circuits, and backup uninterruptible power supply, thus achieving a complete power-off. If the system fails to complete the shutdown process normally, the main control board will prompt the user on the human-machine interface to manually intervene or perform a forced shutdown. This prevents data loss, software corruption, or system configuration errors caused by sudden power outages, ensuring the integrity of equipment data and system stability.

[0064] Based on the same concept, this application also discloses a device start-up control method, applicable to the device start-up control system described in any of the above embodiments. (See attached specification) Figure 2 As shown, specifically, one embodiment of a device startup control method according to this application includes the following steps: S1, in response to the power-on signal, determines whether the device is connected to the mains power supply through the power control board.

[0065] S11, If ​​the mains power supply is connected, the device enters the normal startup state. At this time, the mains power supply is activated to supply power to the entire device.

[0066] S12, if not connected to the mains power supply, upon receiving the power-on signal, the device enters a standby state and begins timing. At this time, the backup power supply is activated to provide power to the electric ground brake control module.

[0067] S2, within the preset parking time threshold, determine whether the electric ground brake control module has received an operation command.

[0068] S21, if the operation command is not received, the power supply to the electric ground brake control module is stopped after the parking time threshold expires, and the device exits the parking state.

[0069] S22, if the operation instruction is received within the lingering time threshold, the timer is restarted after the operation instruction is executed.

[0070] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0071] Based on the same concept, this application also discloses a mobile medical device comprising a device start-up control system as described in any of the above embodiments.

[0072] The device start-up control system, method, and mobile medical device of this application have the same technical concept, and the technical details of the embodiments of the three are applicable to each other. To reduce repetition, they will not be described again here.

[0073] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the above-described division of program modules is merely an example. In practical applications, the above functions can be assigned to different program modules as needed, that is, the internal structure of the device can be divided into different program units or modules to complete all or part of the functions described above. The program modules in the embodiments can be integrated into one processing unit, or each unit can exist physically separately, or two or more units can be integrated into one processing unit. The integrated unit can be implemented in hardware or as a software program unit. Furthermore, the specific names of the program modules are only for easy differentiation and are not intended to limit the scope of protection of this application.

[0074] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
