Description

Technical Field

[0001] The invention relates to the field of optical measurement system control, and in particular to a control protection design system and method for a large-load optical measurement system. Background Art

[0002] Optical measurement systems are playing an increasingly important role in modern weapon systems and range measurements. They are not affected by complex electromagnetic environments. They use infrared thermal imagers, visible light cameras, laser rangefinders and other optoelectronic payloads to conduct long-range search and detection of targets such as aircraft, missiles, and artillery shells, and provide high-precision measurement data of targets for guidance, miss distance measurement, and trajectory measurement. The detection power of the optical measurement system is directly related to the effective aperture of the optoelectronic payload. In the field of ground-based ship optical measurement, with the increase in the demand for detection power, the aperture is getting larger and larger. At the same time, the size and power of the servo turntable that drives the operation of the optoelectronic payload are also getting larger, and the cost of the optoelectronic payload has increased significantly. Large-load optical measurement systems generally have an independent power supply to power the servo turntable. When the power supply is abnormal or the power is cut off, or the current, angle measurement and other sensors are operating abnormally, the servo turntable is at risk of stalling or running away, resulting in the loss of control of the high-power servo turntable and damage to equipment or personnel.

[0003] In traditional large-load optical measurement systems, one way to achieve control protection is to strictly regulate the operation sequence of personnel. During debugging or use, it is strictly stipulated that the power supply should be started before the control drive unit, and the drive enable should be turned off in time when the power supply is powered off. When the power supply is powered off and the control drive unit is operating normally in a closed loop, re-energizing the power supply will cause the car to run away. Operators are strictly required to pay attention to current over-limit and angle over-limit to avoid stall failure.

[0004] The other is to strictly rely on external sensors for control and protection. To ensure measurement and control accuracy, large-load optical measurement systems are generally directly driven by torque motors, which have certain continuous and peak stall capabilities. Using current sensors to only protect the current amplitude from over-limit cannot effectively take into account the ability of the torque motor to exert its peak stall torque and protect against stall faults. When the current sensor fails, the optical measurement system loses its ability to protect. In addition, monitoring the current alone cannot effectively avoid runaway faults, and additional hardware is still required. Summary of the invention

[0005] The purpose of the present invention is to provide a control and protection design method for a large-load optical measurement system to solve the problem that the large-load optical measurement system may be blocked or runaway due to misoperation or equipment failure, which may cause damage to equipment or personnel.

[0067] Please refer to Figure 1 and Figure 2 The specific steps of another large-load optical measurement system control protection design method of the present invention are as follows:

[0068] The first step is to build a large-load optical measurement control and protection system

[0069] The large-load optical measurement control and protection system includes: a comprehensive information processing unit, a control drive unit, a drive power supply unit and a photoelectric load.

[0070] The comprehensive information processing unit is composed of a display and control computer, an image processing board, etc. Its functions are: to control the motion of the photoelectric load through the control drive unit according to the work flow; to receive the fault status, system working status and measurement data information output by the display control drive unit; and to clear the fault code of the control drive unit after the fault of the control drive unit is eliminated.

[0071] The control drive unit is composed of a servo control circuit, a servo drive circuit, a servo turntable, etc. Its functions are: receiving instructions from the comprehensive information processing unit to drive the photoelectric load to move; performing closed-loop and open-loop dual fault judgments in the form of output current and duty cycle over-limit timing, and shutting down the drive enable and latching the fault information for control protection when a fault occurs; and sending fault status, system working status and measurement data information to the comprehensive information processing unit.

[0072] The drive power supply unit is composed of a power supply module, and its functions are: to provide power for the control drive unit, and to close or disconnect the power supply through a switch; to disconnect the power supply during system debugging, maintenance or long-term standby to ensure the safety of equipment and personnel.

[0073] The optoelectronic payload consists of an infrared thermal imager, a visible light camera, a laser rangefinder, etc. Its function is to image and measure the target scene under the drive of the control drive unit.

[0074] The output end of the integrated information processing unit is connected to the input end of the control drive unit; the output end of the drive power supply unit is connected to the input end of the control drive unit; the output end of the control drive unit is connected to the integrated information processing unit; and the input end of the photoelectric load is connected to the control drive unit through a mechanical structure.

[0075] The second step is to control the drive unit for control protection

[0076] At the beginning of a control cycle, the integrated information processing unit first enters the control protection module. The control protection module determines whether it is currently in the drive enable state. If not: if the first frame drive enable instruction received by the integrated information processing unit is received, the drive enable state is set and the fault code and fault timer are cleared, and further execution is performed to the fault judgment module; if not, this control cycle is directly exited without performing any drive photoelectric load action. If yes: continue to execute to the fault judgment module.

[0077] For the convenience of description, the following definitions are given:

[0078] The drive enable flag is Start, which is 1 when the drive is enabled, otherwise it is 0;

[0079] Current c t , is the real-time current value measured by the current sensor;

[0080] Current over-limit time threshold T cur The value is selected based on the principle that it can cover the duration of the starting and stopping peak current under all normal working conditions; it can be 50% of the maximum rotation time of the servo turntable, and not exceed the maximum peak stall time allowed by the servo turntable, whichever is greater;

[0081] Current over limit threshold C lim , the value can be 90% of the peak locked-rotor current;

[0082] Current over limit timer n cur ;

[0083] Duty cycle d t , is the real-time duty cycle value;

[0084] Duty cycle exceeding time threshold T dut The value is taken as the maximum continuous full voltage output time under all working conditions, plus a certain margin, which is generally 2T cur ;

[0085] Duty cycle exceeding threshold D lim , the value can be 0.9;

[0086] Duty cycle over limit timer n dut ;

[0087] A control period T, for example 100us.

[0088] For example: At the beginning of a control cycle, the control protection module determines whether Start is 1. If so, it continues to execute to the fault judgment module. If not, if the first frame drive enable instruction is received, set Start = 1, n cur =0, n dut =0; if not received, exit this control cycle directly.

[0089] The third step is to control the drive unit to perform closed-loop and open-loop dual fault judgment

[0090] In one control cycle, the control protection module executes to the fault judgment module. The current sensor monitors the current, and counts when the current exceeds the current over-limit threshold. When the timing exceeds the current over-limit time threshold, the drive enable is turned off, the photoelectric load is stopped, the stall fault is reported to the integrated information processing unit, and the control cycle is exited, avoiding the motor and drive component burnout damage caused by the servo turntable stall fault in a closed loop.

[0091] Specific example: If the current c t Greater than C lim , then n cur =n cur +1, and further determine if n cur Greater than The stall protection program is triggered, the enable is turned off, Start=0, and this control cycle is exited; if c t No more than C lim , then n cur =0, in order to realize the continuous over-limit judgment of the current and further execute downward;

[0092] When the duty cycle exceeds the threshold, the timing is performed. When the timing exceeds the duty cycle exceeding time threshold, the drive enable is turned off, the photoelectric load is stopped, the integrated information processing unit is driven to fail, and the control cycle is exited. The servo turntable runaway failure caused by abnormal power supply of the power supply unit is protected in an open loop form to avoid impact damage to the photoelectric load. If no fault is determined, the execution continues to the drive execution module.

[0093] Specific example: If the duty cycle d t Greater than D lim or less than (1-D lim ), then n dut =n dut +1, and further determine if n dut Greater than The flying car protection program is triggered, the enable is turned off, Start=0, and this control cycle is exited; if d t No more than D lim and not less than (1-D lim ), then n dut =0, in order to realize the continuous over-limit judgment of duty cycle and further execute downward;

[0094] The fourth step is to control the drive unit to drive execution

[0095] In one control cycle, the fault judgment module executes to the drive execution module. The drive execution module determines the working mode such as position and speed according to the instructions output by the comprehensive information processing unit, and drives the photoelectric load to move according to the instructions.

[0096] The present invention achieves the following significant beneficial effects:

[0097] The implementation is simple, including: the comprehensive information processing unit outputs drive enable and working mode instructions to the control drive unit; the drive power supply unit provides power to the control drive unit, and can close or disconnect the power supply through a switch; the control drive unit performs closed-loop and open-loop dual fault judgments in the form of output current and duty cycle over-limit timing, and when a fault occurs, the drive enable is turned off and the fault information is latched for control protection. When there is no fault, the optical measurement system is driven and executed according to the comprehensive information processing instructions; the control drive unit sends the fault status, system working status and measurement data information to the comprehensive information processing unit; the control drive unit drives the photoelectric load to move.

[0098] By using the output current and duty cycle over-limit timing, closed-loop and open-loop dual judgment and protection are performed on the stall and runaway faults. The output current over-limit timing is in the form of closed-loop protection. By using an external current sensor to monitor whether the over-limit current has timed out, it neither limits the torque motor's peak stall torque capacity nor avoids stall faults; the output duty cycle over-limit timing is in the form of open-loop protection, which does not rely on external sensors or add hardware, and completely avoids runaway faults from the output end of the control algorithm. It ensures the short-term peak performance of the large-load optical measurement system, solves the problem of equipment or personnel damage caused by stall or runaway faults caused by misoperation or equipment failure in the large-load optical measurement system, and improves the safety of the large-load optical measurement system.
