Description

[0001] A GUIDED WEAPONS ASSEMBLY AND METHOD FOR CONTROLLING POWER OF THE SAME [0002]

The present invention relates to a guided weapon assembly and a power supply control method thereof, and more particularly, to a guided weapon assembly capable of supplying power to a remote measurement apparatus using an ultracapacitor and a power supply control method thereof.

In recent years, the use of uninterruptible power supply (UPS) equipment has been introduced to overcome this problem for equipment that can be seriously affected by voltage fluctuations in the power supply, such as medical facilities, storage devices, computer systems, emergency equipment, . UPS devices serve to provide uninterruptible and high quality power in nonlinear loads. UPS devices can be implemented with various types of energy storage devices such as batteries and flywheel energy storage devices. Ultracapacitors, which are eco-friendly materials that do not have limitations on double-cycle life and contain no toxic substances, are attracting attention .

 An ultracapacitor is also referred to as a supercapacitor or goldcapacitor as a term for an energy storage device having a much higher capacity than a capacitor or an electrolytic capacitor. Ultracapacitor is a power source that collects a lot of energy and emits high energy for tens of seconds or minutes, and is a useful component that can fill the performance characteristics that conventional capacitors and secondary batteries can not accommodate. The characteristics of an ultra capacitor are summarized as follows: (i) it simplifies the electric circuit because it does not cause overcharge / over discharge and provides a factor to lower the price, (ii) has a wide endurance temperature characteristic (-40 ° C to + 85 ° C) , and iii) it is composed of environmental materials, such as condensers and rechargeable batteries.

Separately, the guided weapon system completed through the system development process undergoes a number of test evaluations. Telemetry is the essential device required to verify the requirements of the system development phase during the test evaluation and to evaluate the performance of guided weapons. The telemetry device is a device that monitors the measurement signals of the other constituent devices in the guided weapon and the various sensors used between tests, and collects and transmits data. The information of the guided weapons collected through the telemetry device is largely classified into digital signal, discrete signal and analog signal. The information of the sensor such as vibration, stress, temperature, and various electronic equipments, A navigation device, a navigation device, a driving device, a command receiving device, and the like.

Conventional telemetry devices are powered by i) a powered device from a guided weapon or ii) from a separate power source. The use of a powered device of the guided weapon has the advantage of simplifying the implementation of the telemetry device. However, if a problem occurs in the power system due to the abnormal operation of the guided weapon, the telemetry device can not normally perform signal measurement, which is the function of the telemetry device, so that it can not help in the cause analysis of the abnormal operation of the guided weapon in the situation . Alternatively, if the telemetry device has its own power source, the telemetry device can perform its function independently, even if a problem arises with the guided weapon in flight and a problem arises with the power system of the guided weapon. Thus, it is possible to continuously transmit the abnormality measurement information of the guided weapon. Therefore, the guided weapon telemetry device is preferably provided with a separate power source device to ensure independence of operation and stable measurement. A thermal battery or a secondary battery is mainly used as a separate power supply device of the conventional telemetry device.

Thermal batteries are prepared by dissolving inorganic salt electrolytes, which are electrically insulated at room temperature, with a molten salt immediately (approximately 1 second or less) using pyrotechnic heat sources, To provide a high output in a relatively short period of time by activating the primary battery. It has excellent long-term storage characteristics (more than 10 years) because there is almost no self-power generation because it is sealed in an inactive state until electrolyte is melted, maintenance activity is unnecessary, reliability (acceleration, vibration and shock) is excellent , Has a wide operating temperature range and is widely applied to military applications mainly. Therefore, it is mainly used in many guided weapon systems, operation reliability is verified, and stable power supply is possible. However, since the thermal battery requires a separate squib signal from the outside for the initial operation, the related circuit is required to be implemented. The thermal battery can be used only once, is relatively bulky and is expensive, There is a disadvantage that it occurs.

Ni-Cd, Ni-Mh, and lithium ion batteries are used as secondary batteries for military use, and interest in lithium polymer batteries is increasing. The secondary battery is formed by combining a plurality of unit cells. The higher the voltage of the unit cell and the higher the energy density, the more advantageous it is. However, even in the case of a secondary battery, a separate signal is required for the first operation, and there is a greater risk of explosion and ignition compared to a thermal battery. In addition, since the performance of the secondary battery is drastically deteriorated at a low temperature of minus zero, a separate preheating circuit is required for operation. This leads to an increase in the size of the secondary battery, which makes it difficult to apply to a small induction weapon system. Further, since the secondary battery discharges slightly even in the standby state, there is a disadvantage that the secondary battery must be continuously charged.

There has been a problem in that a separate power supply device can not be added in the case of some guided weapons due to the disadvantages of the thermal battery and the secondary battery,

More specifically, the separate power supply requires: i) miniaturization to meet limited space and weight requirements for guided weapons; ii) stable supply of power in all environments where guided weapons are tested. And iii) there is a price advantage.

The characteristics of the above-described thermal battery, secondary battery and ultracapacitor are shown in Table 1 below.

FIG. 1 is a schematic view of a guided weapon assembly according to the present invention, and FIG. 2 is an equivalent circuit diagram when power is supplied from a UPS to a telemetry device in the guided weapon assembly according to the present invention. Referring to FIGS. 1 and 2, an induction weapon assembly according to the present invention includes a guided weapon 100, a telemetry device 200, and a Uninterruptible Power Supply (UPS) 300.

The power supply unit 110 and the grounding unit 120 are incorporated in the guided weapon 100.

The telemetry device 200 receives power from the power source device 110 and generates data of the guided weapon 100 during the test evaluation of the guided weapon 100. During the test evaluation, the data of the guided weapon 100 can be broadly divided into digital signals, discrete signals, and analog signals.

In addition, an EMI filter and a DC / DC converter may be incorporated in the telemetry device 200.

A UPS (Uninhibited Power Supply) 300 is charged by receiving power from the power supply unit 110. When power is not supplied from the power supply unit 110 to the telemetry device 200, 200 as shown in FIG.

The Uninterruptible Power Supply (UPS) 300 includes an ultracapacitor assembly 310, a balance circuit 320, a current limiter 330, and a reverse current prevention circuit 340.

The ultracapacitor assembly 310 includes a plurality of ultracapacitors 311 connected in series.

The reverse current prevention circuit 340 may prevent power supply from the ultracapacitor assembly 310 to the power supply unit 110 when power is not supplied from the power supply unit 110 to the ultracapacitor assembly 310 .

Hereinafter, the operation of the present invention will be described in detail.

When the power supply apparatus 110 of the guided weapon 100 is in a normal state, the telemetry apparatus 200 receives power from the power supply apparatus 110 and operates. Also, the UPS 300 is powered by the power supply unit 110 and is charged.

The UPS 300 is automatically switched to the power source of the telemetry device 200 when an error occurs in the induced weapon 100 and the power source device 110 does not operate normally. The ultracapacitor assembly 310 of the UPS 300 is discharged to supply power to the telemetry device 200. At this time, the total voltage (_) of the ultracapacitor assembly 310 is the sum of the voltages of the respective ultracapacitors 311 (see Equation 1 below).

The discharging characteristic of the ultracapacitor assembly 310 is determined by the capacitance and the internal resistance of each ultracapacitor 311 (see Equation 2 below).

Is determined by the power consumption of the telemetry device 200 (see Equation 5 below).

As a result, the voltage drop with time of the ultracapacitor assembly 310 is expressed by Equation (6).

)을 조절할 수 있다.That is, considering the voltage drop of Equation (6), from the ultracapacitor assembly 310 to the telemetry device 200 for a preset time after the power supply from the power supply 100 is stopped, So that the telemetry apparatus 200 can operate. The buffering voltage of the ultracapacitor assembly 310

) Can be adjusted. At this time, by varying the number or the capacity of the ultracapacitors 311, the buffering voltage of the ultracapacitor assembly 310

) Can be adjusted.

The preset time may be set differently according to the designer's intention. For example, the preset time may be set to a time of several seconds to several tens of seconds. The predetermined time may be set to a predetermined time during a relatively short period of time until the test of the guided weapon is stopped due to the fall of the guided weapon 100 or the like when the power supply unit 110 of the guided weapon 100 is abnormal, (200) can be operated.

Therefore, as shown in Table 1, the UPS can be constructed using the ultracapacitor 311 having a shorter discharge time than the thermal battery or the secondary battery. In addition, the ultracapacitor 311 has a shorter charging time than the thermal battery or the secondary battery, has a significantly higher number of times of charging and discharging, is operable at a lower temperature, is relatively small in size, and is inexpensive. Accordingly, the UPS 300 using the ultracapacitor 311 can be used as a power source of the telemetry device 200, and thus, a more reliable induction weapon system can be developed.

FIG. 3 is a flowchart of a power control method for a guide-and-assemble assembly according to the present invention. Referring to FIG. 3, the method for controlling power of the guided weapon assembly according to the present invention includes determining whether power is supplied from the power supply unit 110 of the guided weapon 100 to the telemetry apparatus 200 (S100); When power is not supplied from the power supply unit 110 of the guided weapon 100 to the telemetry device 200, power is supplied to the telemetry device 200 from the uninterruptible power supply 300 (S200); And determining whether the total voltage of the ultracapacitor assembly 310 is less than a minimum operating voltage of the telemetry device 200 after the step S200.
