Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present embodiment provides a kind of intelligent power supply control system for float type high-frequency ground wave radar, by the cooperation process of power-supplying circuit and power supply control upper computer software, can meet the power supply control demand of float type high-frequency ground wave radar.
The composition of this electric power supply control system and signal stream as shown in Figure 1, comprising: governor circuit, telecommunication circuit, sample circuit, driving circuit and interface circuit; Peripherals is PC control unit, the water inlet alarm unit of high-frequency ground wave radar and power module.
Described power module is used for for whole float type high-frequency ground wave radar (hereinafter referred to as sonobuoy radar) power supply, and power module comprises solar panel group, battery pack and voltage transformation module.Wherein, solar panel group absorbs sun power, and converts it into electric energy, then accumulators group charging.Battery pack store electrical energy, and be converted to required voltage by voltage transformation module, each equipment being sonobuoy radar respectively by corresponding voltage port is powered.For ensureing the reliably working of power module, the duty of voltage transformation module just seems especially important.
Described sample circuit gathers temperature and the electricity (electricity of described voltage transformation module and the electricity of battery pack) of voltage transformation module, to obtain the duty of voltage transformation module.Wherein the sampling of temperature is realized by the temperature sensor be arranged on voltage transformation module; When sampling to the electricity of voltage transformation module, because the input port of voltage transformation module is connected with battery pack, the voltage of this port of Direct Sampling just can obtain the electricity of battery pack.Described sample circuit gathers the supply voltage of each equipment on sonobuoy radar simultaneously.
The steering order that the water inlet alerting signal that described governor circuit receives the sampled signal (comprising the supply voltage of each equipment on the temperature of voltage transformation module, electricity and sonobuoy radar) of sample circuit transmission, alarm unit of intaking sends, PC control unit are sent by telecommunication circuit; Described governor circuit can send control system of switching on or off electricity signal by driving circuit and interface circuit to power module simultaneously.
Described PC control unit provides the interface of man-machine interaction, and operator can pass through Telnet, realizes the direct control system of switching on or off electricity of equipment selected on radar or the working time section arranging each equipment on radar, allows its automatic power on-off.
Consider that sonobuoy radar is operated in pelagic realm, can only by solar powered, the electricity that Changes in weather is easy to have influence on whole system stores; And equipment needs long-term work at sea to test, use electric energy must be saved as far as possible.Therefore, each module in this electric power supply control system all selects chip and the device of low-power consumption, as described in governor circuit adopt 16 super low power consuming single chip processor chip MSP430F5438A, it carries 16 road Sampling Interfaces also can meet sampling to each equipment voltage.Sample circuit adopts four-operational amplifier chip LM224, and the features such as this chip has supply voltage wide ranges, and quiescent dissipation is little meet the demand that system low-power consumption runs.Because sonobuoy radar system needs the equipment of communication many, and communication distance length has a long way to go, and therefore telecommunication circuit uses RS232 communication to communicate with RS422 simultaneously, and uses serial expanded circuit, increases communication port quantity.Telecommunication circuit serial ports expansion part adopts serial port extended chip SC16IS752, and the operation that this chip is lower and sleep current well can meet the demand of system low-power consumption.
The principle of work of this electric power supply control system is:
First, sample circuit is sampled to the temperature of voltage transformation module, electricity and each equipment supply voltage, then the signal after sampling is sent to governor circuit; The water inlet status signal of alarm unit of simultaneously intaking also is real-time transmitted to governor circuit; Control command on the other hand from PC control unit sends to governor circuit by telecommunication circuit.The steering logic that governor circuit is arranged according to its inside, sends to driving circuit by the power on/off signal of relevant device, and the power on/off being realized corresponding device by the relevant voltage port of driving circuit control voltage modular converter operates.The port that described voltage transformation module provides two-way externally to export, is respectively main part and backup.
The steering logic of described governor circuit is as shown in Figure 2:
Because sonobuoy radar is at pelagic division Jobs on the sea, stormy waves is very large, should pay close attention in the moment in battery flat (accumulator is contained in the battery flat of buoy platform) and equipment compartment (power supply and equipment are contained in equipment compartment) with or without water inlet; For this reason, be provided with in the battery flat and equipment compartment of sonobuoy radar into water alarm unit, in real time water inlet status signal sent to governor circuit.
The water inlet status signal that described governor circuit is sent according to the water inlet alarm unit being positioned at battery flat and equipment compartment, judge whether cabin body (battery flat and equipment compartment) intakes: if cabin body (battery flat and/or equipment compartment) water inlet, then governor circuit sends power down control signal to driving circuit, carry out delay cut-off by driving circuit to voltage transformation module, thus close the operating voltage of each device port; If battery flat and equipment compartment are not all intake, then voltage transformation module is each equipment normal power supply.
The temperature limit of voltage transformation module is provided with in described governor circuit, whether normal for judging the work of power module.The temperature limit of the temperature of the voltage transformation module that sample circuit is sent by governor circuit and the voltage transformation module set by its inside is compared, when the temperature of voltage transformation module exceedes this temperature limit, governor circuit automatically switches to the fallback circuit of voltage transformation module.
Be provided with the value range of each equipment operating voltage on sonobuoy radar in described governor circuit simultaneously, the supply voltage signal of each equipment that governor circuit is sent according to sample circuit, the voltage range values corresponding with this equipment is compared, and judges that whether normal (namely whether in the operating voltage range of setting) each equipment operating voltage.If equipment operating voltage normal (in the operating voltage range of setting), then the control command normally receiving PC control unit is that relevant device is powered; If equipment operating voltage abnormal (not in the operating voltage range of setting), then give relevant device power-off.
The control command of PC control unit comprises two kinds, is respectively real-time control command and working time section control command.When governor circuit receives the real-time control command to certain equipment, immediately power on/off operation is carried out to this equipment; When governor circuit receives the working time section control command to certain equipment, then corresponding in the instruction moment is energized and power-off to relevant device.Because on sonobuoy radar, some equipment only needs discontinuous operation, adopt this kind of control method, can effective saves energy.
Because on sonobuoy radar, some electricity consumption of equipment amounts are very large, but these equipment can not work and have influence on the operation of whole radar system the long period, as transmitter, it plays optimization function to the reception of receiver signal, only has and just can open when electricity abundance time.For this reason, governor circuit carries out Based Intelligent Control according to the electricity of power module to these equipment.Be specially: the power supply port of the correspondence of this kind equipment that first prestores in governor circuit, when governor circuit judges that electric quantity of power supply is more than or equal to the threshold value of its inner setting, show that current electric quantity is sufficient, then open this kind equipment; When electric quantity of power supply is less than the threshold value of setting, then close this kind equipment, thus ensure that sonobuoy radar runs sustainedly and stably.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
