It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the respective embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The terms "first," "second," "third," and the like in the description and claims of this application and in the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but may alternatively include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1, a steering engine management system based on an integrated power supply according to a first embodiment of the present invention includes: a rudder system control circuit, a power supply management circuit and an actuating mechanism. Wherein, the rudder system control circuit includes for example: the device comprises a communication circuit 2, a DSP circuit 1, an isolation driving circuit 5, a power amplifying circuit 6, a secondary power supply circuit 3 and an A/D conversion circuit 4; the power management circuit includes, for example: a bus circuit 7, a current collection circuit 9 and a voltage collection circuit 10.
The rudder system control module is communicated with an upper computer through an RS422 bus communication circuit, for example, the DSP circuit 1 adopts a digital signal processor TMS320F2812 as a CPU processing unit, receives a control instruction obtained through the RS422 communication circuit 2, receives a position feedback signal of the rudder system executing mechanism, calculates a PWM signal with adjustable duty ratio through an A/D conversion circuit 4, isolates the PWM signal through an isolation driving circuit 5, amplifies the PWM signal through a power amplification circuit 6, outputs three-phase voltage to drive the executing mechanism to rotate, and achieves closed-loop control.
The secondary power supply circuit 3 is implemented by, for example, a power supply filter, a power supply module, etc., and filters a control power supply provided by the system, and then secondarily converts the control power supply into 5V, 3.3V, 1.8V, ± 10V, 15V, etc., where 3.3V and 1.8V are used for supplying power to the DSP circuit 1, 5V is used for supplying power to the digital circuit, and ± 10V is used for supplying power to the actuator sensor and the analog circuit. The a/D conversion circuit 4 is implemented by, for example, an AD7656 conversion chip, and converts analog quantities such as a rudder feedback signal, a voltage signal, and a current signal into digital quantities, and then completes signal interaction with the DSP circuit 1 through an external interface.
The confluence circuit 7 is used for converging the multi-circuit thermal batteries and preventing the circulation current from forming between the two batteries. In one embodiment, as shown in fig. 2, which is a schematic diagram of a bus circuit 7, taking a two-way thermal battery as an example, the negative terminal-DP of the thermal battery is connected together, and the positive terminals DC1 and DC2 of the two-way thermal battery are isolated and merged by a two-way fast recovery rectifier diode RUG 5060. The current acquisition circuit 9 acquires the current of the thermal battery, and the voltage acquisition circuit 10 detects and acquires the voltage of the thermal battery before and after confluence.
The A/D conversion circuit 4 also sends the collected current information and voltage information to the DSP circuit 1 for resolving and information feedback. Therefore, the power supply management device is integrated in the rudder system, analog signals such as voltage, current and the like collected by the power supply management device are transmitted to the rudder system control circuit module through the connector, and then are converted into digital signals through the A/D module. Because the rudder system needs to be communicated with an upper computer, voltage and current acquisition information is added in the original rudder system-upper computer communication protocol. The design integrates and reuses the repeated circuit modules in the rudder system and the power supply management device, and the integrated design can greatly reduce the cost and has obvious advantages on the basis of realizing the original functions.
In one embodiment, the power management circuit further includes, for example: and the self-checking circuit 8 is used for performing self-checking before the power electricity is configured through the secondary power supply circuit 3, configuring the power electricity to the voltage acquisition circuit 10 after the self-checking is successful, and suspending the input of the voltage acquisition circuit 10 when the power electricity is not configured without performing self-checking.
In one embodiment, the power management circuit further includes, for example: and the pump-up voltage release circuit 11 is arranged between the output end of the voltage acquisition circuit 10 and the input end of the power amplification circuit 6, and is used for releasing the pump-up voltage generated in the motor braking process to generate power electricity output so as to protect components such as a driving circuit, a filter capacitor and the like in the rudder system.
Specifically, as shown in fig. 3, which is a schematic diagram of a self-checking circuit, the self-checking circuit 8 is implemented by, for example, an alternative analog switch, where a B0 signal is output as an analog quantity of voltage division conversion of +15V of a driving voltage in the pumping voltage bleeder circuit 11, a B1 signal is output as an analog quantity of power supply + DP voltage division conversion, and an output terminal AOUT is connected to an input terminal of the voltage acquisition circuit 10. When power electricity is not distributed, after a rudder system receives a self-checking instruction, the DSP circuit 1 generates a switching signal SEl to be a high level, at the moment, the two-way analog switch outputs a B0 signal, the voltage acquisition circuit 10 acquires a +15V signal and judges the signal through the DSP circuit 1, and when the error requirement is met, the self-checking is qualified. After the self-checking is finished, SEl is set low, the two-out analog switch outputs a B1 signal, and the voltage acquisition circuit 10 acquires the + DP power electric voltage.
As shown in fig. 4, which is a schematic diagram of a pump-up voltage bleeder circuit, a pump-up voltage is generated during a motor braking process, and an excessively high pump-up voltage affects a power tube, a filter capacitor, and the like, and the pump-up voltage bleeder circuit 11 is designed for protecting devices such as a driving circuit and the filter capacitor. A voltage acquisition signal and a voltage reference value are input into a comparator D1, when the voltage acquisition signal exceeds the comparison value, a switch signal SWA outputs low level, at the moment, a photoelectric coupler B1 is conducted to drive an MOS (metal oxide semiconductor) tube to be opened, and the voltage is consumed and discharged through power resistors R6 and R7 to prevent the voltage from being reduced below a threshold value. When the voltage is below the threshold value, the switch signal SWA outputs a high level, the optical coupler is not conducted, and the bleeder circuit does not work. The voltage reference value can be configured through the resistors R1 and R2, and different pumping voltage discharge threshold values can be obtained through the configuration of different resistance values.
