Technical Field

The invention belongs to the technical field of missile launching control, and relates to a secondary dump type micro-power-consumption wireless data binding device and method.

Background

The intelligent ammunition can be configured with different striking effects through data binding. The traditional wired data binding mode needs to plug and pull cables in the binding process, so that the binding time is influenced, and the requirements of batch binding and quick emission cannot be met. Wireless data binding is becoming the direction of smart and intelligent ammunition technology development.

The basic principle of wireless data binding is to use wireless communication instead of wired information interface. For example, the publication No. CN 112050691 a, and documents such as "design and implementation of wireless bookbinding system based on SimpliciTI", "data transmission technology of semi-strapdown inertial measurement system for spinning bullets", and "application of bluetooth technology to parameter bookbinding". This kind of method only solves the wireless information, and the thermal battery in the cartridge must be activated to supply power to the binding system before binding, and once the thermal battery is activated, it cannot be restored, so that the wireless data bound ammunition can only be used once.

The wireless data binding systems disclosed in the patent publication nos. CN 109115036 a and CN 111260903 a have the additional capability of providing temporary power supply for the binding process by adding a wireless power supply module, without activating a thermal battery in the cartridge, and having the capability of binding data for multiple times. However, the processes of data receiving and storing in wireless data binding require cooperation of the onboard computer, the power consumption of the onboard computer is usually in the order of several watts to tens of watts, the wireless power supply power must be higher than the peak power consumption of the onboard computer, and the following problems exist in the practical application of wireless data binding:

(1) small caliber ammunition faces insufficient transmission power. The power of various wireless power supply modes is positively correlated with the transmission area, even if the magnetic coupling mode with the highest efficiency is adopted at present, the coupling area of dozens to hundreds of square centimeters is required for meeting the power consumption of the missile-borne computer, and in ammunition with the missile diameter smaller than about 50 millimeters, the missile-borne computer cannot be driven due to the limitation of the windowing area on the surface of the missile.

(2) Transmission efficiency is limited in medium and long distance applications. There are certain applications where it is desirable for the data binding system and projectile to maintain a safe distance or mechanical tolerance of more than a few tens of centimeters, such as for instance the completion of data binding in ammunition in a chain of ammunition, the long range wireless data binding referred to in patent publication CN 109115036 a. The transmission efficiency of various long-distance wireless power supply modes (microwave transmission, photoelectric conversion and sound wave power supply) is usually not more than 10%, and the problem of insufficient receiving power is further aggravated by increasing the binding distance.

(3) There is a lack of adaptability to insufficient power supply. Due to the fact that displacement deviation is caused by strong mechanical vibration in the practical application environment, received energy of the binding system fluctuates, and the possibility that instantaneous power supply cannot meet transient consumption of the missile-borne computer exists. Once the actual instantaneous power supply is insufficient and the system is powered down, the data needs to be transmitted from the beginning again after the system is powered on and reset again, which increases the time for data binding, and the problem is particularly obvious in large-volume binding (such as terrain matching maps and target image data).

In the case of the example 2, the following examples are given,

a secondary dump type micro-power consumption wireless data binding method is divided into two branches of a wireless binding task and an on-cartridge loading task of data, after a micro-power consumption embedded system 13 is powered and activated, the micro-power consumption embedded system 13 judges whether the task executed by the micro-power consumption embedded system 13 is the on-cartridge loading of the data or the wireless binding of the data according to the current power supply source; if the task executed by the micro-power embedded system 13 is on-board loading, loading data to the on-board computer 18 through the on-board communication interface 16; if the task executed by the micro-power embedded system 13 is wireless binding, the wireless binding of the data is realized in an asynchronous request response mode, and the binding step not only has the function of breakpoint retransmission, but also can realize energy-time comprehensive benefit constraint; specifically, in order to prevent frequent power failure of the system due to insufficient energy storage and increase data binding time, the data packet transmission process is initiated by the receiving end 2 each time, and the energy prejudging and energy self-adapting steps are executed before the transmission request is sent each time.

In some embodiments, a two-time dump type micro-power consumption wireless data binding method, as shown in fig. 2, is specifically performed according to the following steps:

step 1, judging whether a task executed by the micro-power consumption embedded system 13 is data pop-up loading or data wireless binding by the micro-power consumption embedded system 13 according to a current power supply source; loading data to the on-board computer 18 if the task performed by the micropower embedded system 13 is on-board loading, based on the results of the thermal battery power-up detection module 15; the micro-power consumption embedded system 13 reads the binding data in the transfer memory 14, simulates the behavior of the ground test launch control system 6, binds the data into the missile-borne computer 18, and ends the program; if the task executed by the micro-power embedded system 13 is wireless binding, step 2 is executed sequentially.

Step 2, energy prejudging and energy self-adapting; the micro-power consumption embedded system 13 obtains the energy storage module 10 through the energy detection module 11Residual electric quantity, the micro-power consumption embedded system 13 predicts the predicted energy threshold value of the next packet of handshake communication, and self-adapts the energy state according to the current residual electric quantity and the predicted energy threshold value, and step 3 is sequentially executed until the energy of the micro-power consumption embedded system 13 meets the requirement; in particular, if the present capacitor voltage U_curVoltage threshold value U less than electric quantity prejudgment_thContinuing to wait for charging, entering a low power consumption mode, sleeping for 100ms, and then repeatedly executing the process; if the present capacitor voltage U_curVoltage threshold value U larger than electric quantity prejudgment_thWriting the maximum data length N capable of being received in the transmission request packet_r·maxStep 3 is performed sequentially.

Step 3, judging whether the data in the transfer memory 14 is complete; the micro-power embedded system 13 reads the data in the transfer memory 14 and checks the integrity of the data; if the data in the transit memory 14 is complete or blank, it indicates that the previous binding is normally finished or the data is not bound, and the current binding operation is the newly loaded data, a 1 st packet transmission request is sent, the data is received, verified and stored in the transit memory 14, and the step 5 is executed; if the transfer memory 14 has partial data but is incomplete, it indicates that the apparatus has failed in the last binding, and executes the breakpoint transmission, and then executes step 4 sequentially. The time length of the check sum storage process is short, the power consumption is low, and the influence of the process on the energy storage capacity is negligible.

Step 4, continuous transmission state detection; the micro-power consumption embedded system 13 sends a continuous transmission request, receives the characteristic code of the data to be transmitted sent by the sending end 1, and compares the characteristic code of the data to be transmitted with the characteristic code of the data which is stored in the transfer memory 14 and is not transmitted last time; if the two feature codes are the same, indicating that the data needs to be continuously transmitted, sending a breakpoint packet transmission request, receiving, checking and storing the data to the transfer memory 14, and executing the step 5; if the two feature codes are different, it is indicated that the current binding operation is new data, the original continuous transmission data needs to be covered, the 1 st packet transmission request is sent, the data is received, verified and stored in the transfer memory 14, and the step 5 is executed.

Step 5, energy prejudging and energy self-adapting; micro-power embedded system 13 pass-through energyThe detection module 11 acquires the residual electric quantity information of the energy storage module 10, and adapts the energy state according to the current residual electric quantity and the estimated energy threshold; if the present capacitor voltage U_curVoltage threshold value U less than electric quantity prejudgment_thContinuing to wait for charging, entering a low power consumption mode, sleeping for 100ms, and then repeatedly executing the process; if the present capacitor voltage U_curVoltage threshold value U larger than electric quantity prejudgment_thWriting the maximum data length N capable of being received in the transmission request packet for sending the next packet_r·maxThen step 6 is performed sequentially.

Step 6, carrying out primary data packet transmission; sending a next packet transmission request, receiving, verifying and storing data to the transfer memory 14; if the data packet still remains to be transmitted, repeating the step 5; and if all the data packets are transmitted, ending the process.

In step 2 and step 5, the energy threshold value except the voltage threshold value U is estimated_thBut also can be an electric quantity percentage threshold, but the voltage threshold is most easily realized; the specific steps of predicting the predicted energy threshold of the next packet handshake communication are as follows: the micro-power embedded system 13 calculates the estimated voltage threshold U of the next packet handshake communication according to the formulas (1) to (2)_thReasonably estimating the energy of the handshake communication according to the average rate of energy increase of the previous handshake communication;

wherein, P_predThe average power acquired by the wireless energy receiving module 8 in the predicted handshake communication time period is represented; c represents the capacitance of the energy storage module 10; Δ T represents a time interval from the end of the last data reception to the end of the last data reception, and specifically, the time interval Δ T may be measured by a timer of the low power consumption embedded system 13; u shape_cur1Indicating the remaining capacity, U, at the end of the reception of the last data_cur2The residual electric quantity representing the last data receiving ending moment is measured by the energy detection module 11; r_BRepresents the byte transmission rate; p_eRepresents the average power consumed by the system when sending a transmission request packet; p_rRepresenting the average power consumed by the system when receiving data, P_rAnd P_eThe power consumption parameter of each module chip can be accurately obtained through experimental measurement or is estimated through addition of the power consumption parameters of each module chip. N is a radical of_rRepresents the last received data length, unit: a byte; n is a radical of_eLength of packet indicating the last transmission request sent, unit: a byte; t is_waitIndicating idle timeout latency by N_wait/R_BRepresents, take N_waitIs 5-10 bytes; u shape_minThe minimum voltage value at which the receiver is maintained to operate when the reception data and the transmission request packet are not transmitted is indicated.

The longest data length N that can be received in step 2 and step 5_r·max(unit: byte) passing formula (3) according to the current remaining power U_curAnd (3) calculating:

if the current remaining capacity U_curLess than the estimated voltage threshold U_thContinuing to wait for charging, entering a low power consumption mode, sleeping for 100ms, and then repeatedly executing the process; if the current remaining capacity U_curGreater than the estimated voltage threshold U_thWriting N in the transmission request packet for sending the next packet_r·maxAnd information, realizing the self-adaptive energy state of the micro-power embedded system 13.

Part of the existing energy self-adaptive methods only change the interval of sending messages according to the current energy storage state, the interval of data messages only has a plurality of selectable values, the packet length of the data packets is short and is fixed length (8 bytes), and the requirement on the communication speed is not high (the message is sent once in 1 minute at most).

The embodiment of the invention is oriented to the binding of data stream, the capacity of the bound data is dozens to hundreds of KB, so that the binding method of the invention is required to consider the energy constraint of the system on one hand and prevent the system from frequent power failure due to insufficient energy storage; on the other hand, a high data binding rate is required, and perfect binding of data is accomplished in as short a time as possible, for example, requiring that at least 4KB of data binding must be accomplished per second.

The energy estimation of the invention not only considers whether the current residual energy is enough, but also considers the energy increasing rate. In detail, the binding process itself takes a long time, during which the system receives energy while the energy is consumed. In addition, the energy self-adapting method of the invention adaptively adjusts the length of the received data packet according to the estimated value voltage threshold value and the current state of the remaining capacity before sending the transmission request each time, starts the data frame transmission as long as the energy is enough, allows the frames with any length to be lengthened, and improves the data binding rate on the basis of meeting the energy constraint. For example, the energy estimation and energy adaptive method adopted by the invention can change the packet length in the range of 128 bytes to 1024 bytes according to the energy state of the system, and can complete at least 4KB of data binding in each second.

And the micro-power consumption hysteresis comparator is adopted to realize the power-on detection module 15 of the thermal battery, and is used for identifying the source of the current power supply. Setting the comparison threshold voltage to be 3.3V, if the output voltage of the thermal battery 17 is higher than the comparison threshold voltage of 3.3V, outputting a high level by the micro-power consumption hysteresis comparator, and considering that the thermal battery 17 is in an activated state at the moment, wherein the thermal battery 17 supplies power for the wireless data binding receiving end 2; if the output voltage of the thermal battery 17 is lower than the comparison threshold voltage of 3.3V, the micro power consumption hysteresis comparator outputs a low level, at this time, the thermal battery 17 is considered to be not activated, and the photocell supplies power to the wireless data binding receiving end 2.

The electric energy obtained by the photovoltaic cells is stored by using a 100uF multilayer ceramic capacitor as the energy storage module 10. The LTC3103 series switching regulator is used as a low-power-consumption DC-DC12, has ultra-low static power consumption, and can output stable power supply voltage of about 3.3V.

Step 1, judging the source of the current power supply so that the micro-power consumption embedded system 13 can judge the task branch to be executed. If the micro-power consumption hysteresis comparator outputs high level, the thermal battery 17 is judged to supply power for the wireless data binding receiving end 2, a bullet loading task of data is executed, the MSP430 single chip microcomputer reads binding data in the CY15B102Q ferroelectric memory, the behavior of the ground test launch control system 6 is simulated, the data is bound into the bullet loading computer 18, and the program is ended; if the micro-power consumption hysteresis comparator outputs low level, the wireless energy receiving module 8 is judged to supply power for the wireless data binding receiving end 2, wireless binding of data is executed, and the step 2 is executed in sequence.

And 3, verifying the integrity of the data. The MSP430 singlechip reads the data in the CY15B102Q ferroelectric memory and verifies the integrity of the data. If the data in the ferroelectric memory is complete or blank, the binding operation is normally finished or the data is not bound at the last time, the current binding operation is the newly loaded data, a 1 st packet of transmission request is sent, the data is received, verified and stored to a transfer memory, and the step 5 is executed; if the ferroelectric memory has partial data but is incomplete, the device is powered down in the last binding, and needs to execute breakpoint transmission, and step 4 is executed sequentially.

The MSP430 single chip microcomputer sends a continuous transmission request (character 'U'), receives the data feature code to be transmitted (the file content is mapped to an MD5 value with 16 bits) sent by the sending end 1, and compares the data feature code to be transmitted with the data feature code which is stored in the ferroelectric memory and is not transmitted last time. If the two are the same, the data needs to be continuously transmitted, a breakpoint packet transmission request is sent, the data is received, checked and stored to a transfer memory, and the step 5 is executed.

The average power consumption of the wireless data binding receiving end of the embodiment is only about 0.5 milliwatt, the wireless energy receiving area is only 2.0 square centimeters, the circuit space volume is less than 2 cubic centimeters, and the wireless data binding receiving end can adapt to pre-shooting data binding of intelligent ammunition with small ammunition diameter.

3. Has adaptability to energy status. Along with the increase of binding distance, the time required by energy storage is prolonged, and the communication packet length can automatically shorten. For example, the transmission distance between the bullet body and the data binding system is within 20 cm, so that the transmission of binding data with the length of 1024 bytes of a data packet can be realized, the transmission distance between the bullet body and the data binding system is within 20 cm to 50 cm, and the length of the data packet of the wireless binding system is automatically shortened to adapt to the reduction of energy transmission power. Even if the power supply is completely interrupted in the wireless data binding process, the wireless data binding receiving end can continue to transmit data from the breakpoint position after being reset.
