Description

Device and method for controlling the power supply status according to the test scenario of the explorer {APPARATUS AND METHOD FOR CONTROLLING POWER SUPPLY BASED ON TEST SENARIO OF SEEKER}

The present invention relates to a power supply device and a method for a seeker, in which power consumption profiles of a searcher according to various test scenarios are stored as a pattern, and the power supply status of the searcher according to various test scenarios is monitored based on the power consumption profile pattern. The present invention relates to a method and apparatus for controlling the power supply state of a searcher capable of automatic power control.

A seeker refers to a device that detects or tracks a target and provides the guidance manipulator with the direction or position of the target necessary to calculate the guidance command. These searchers can be classified into active searchers, semi-active searchers, and passive searchers according to the tracking method, and can be classified into ultra-high frequency searchers, millimeter wave searchers, infrared searchers, and laser searchers according to the characteristics of the target signal.

In the process of developing and producing a searcher, equipment must be tested in various ways to verify its performance. At this time, the searcher test according to the test items such as the target distance, the speed of the derivative, the angle, and the transmission power as well as the operating environments such as high temperature, low temperature, vibration, shock, altitude, humidity, salt spray, and EMI/EMC. Scenarios are different, and since the power consumption profile required by the searcher is different for each scenario, providing a stable power supply is a very important factor.

Typically, in the process of testing a searcher, the user directly controls the power supply status of the power supply that supplies power to the searcher, or sets one threshold that can cover all of a variety of scenarios and tests in a single pattern. It is applied to the system to respond to the scenario.

If the user directly controls the power supply status provided to the searcher, since the power supply status must be manually controlled by considering all current profiles according to various test scenarios, there is a possibility that judgment errors and delays in judgment may occur accordingly. This is very high, and there is a possibility that ambiguity in the establishment of the judgment criteria may arise because the judgment criteria are different for each user. In addition, there arises a problem that the system takeover time is prolonged due to user change as a vast number of pattern learning corresponding to various test scenarios is required.

In addition, in the case of controlling the power supply state of the searcher with a single pattern by setting one threshold that can cover all of various scenarios, there is a limitation to apply the maximum threshold in consideration of all test scenarios. In certain test scenarios, the searcher failure may not be identified and may be omitted.

An object of the present invention is to provide an apparatus and method for controlling a power supply state capable of automatically controlling a power supply state of a searcher in consideration of all current consumption profiles according to a test scenario of a searcher.

However, the object of the present invention is not limited to the above-mentioned matters, and other objects not mentioned will be clearly understood by those skilled in the art from the following description.

In the apparatus for controlling power supply status according to the test scenario of the searcher according to an embodiment of the present specification, the change type of the current consumption required for the searcher is a profile pattern corresponding to each of a plurality of test items and a plurality of test scenarios according to the operating environment. A storage unit in which records are stored; And generating a corresponding current consumption profile as a pattern through repeated tests a predetermined number of times for each of the test scenarios and recording and storing them in the storage unit, and supplying power to the searcher based on the profile pattern corresponding to each test scenario. And a control unit that sets a reference value for control and controls a power supply supplying power to the searcher using the profile pattern and the reference value.

In the device, the test item may include at least one or more of the distance of the target, the speed of the derivative, the angle, or the transmission power, and the operating environment is at least one of temperature, vibration, shock, altitude, humidity, salt spray, EMI, or EMC. It may include more than one.

In addition, the reference value for power supply control of the searcher includes a warning reference value and an automatic power control reference value, and the control unit sets the warning reference value as a limit value of ±10% based on the profile pattern, and the automatic power control reference value is ±20% may be set as a limit value based on the profile pattern.

In addition, the control unit monitors the status of the searcher in real time using the profile pattern and the reference value, and automatically controls to generate and output a warning signal when the current profile of the searcher exceeds the warning reference value. When the profile exceeds the limit value, it is possible to automatically control to turn off the power of the power supply.

In addition, the device may further include a user interface through which a user can select a test item and an operating environment, and monitor a state of the explorer, and the user interface is configured by the control unit using the profile pattern and the reference value. A configuration option may be implemented so that the ability to control the power supply that supplies power to the explorer is blocked.

A method of controlling a power supply state according to a test scenario of a searcher according to an embodiment of the present specification includes the steps of repeatedly measuring a change type of a current consumption of the searcher according to the test scenario a predetermined number of times; Extracting the average value of the change form of the repeatedly measured current consumption, setting it as a current consumption profile pattern corresponding to the test scenario, and storing it in a storage unit; Setting a reference value for controlling the power supply of the searcher based on the profile pattern; Monitoring the current consumption of the searcher for a specific test scenario; Comparing the monitored current consumption with a current consumption profile pattern corresponding to a specific test scenario; And automatically controlling a power supply state of the searcher when the current consumption of the searcher exceeds the reference value as a result of the comparison.

According to an embodiment of the present invention, there is an effect of providing a power supply state control apparatus and method capable of automatically controlling a power supply state of a searcher in consideration of all current consumption profiles according to a test scenario of the searcher.

In addition, through this, it is possible to immediately respond to various event situations that may occur during the searcher test, thereby preventing delays and errors from occurring.

In addition, it is possible to prevent the problem of not recognizing a specific test scenario or not identifying a failure of the searcher as in the prior art, and an effect of preventing damage to the searcher due to supply of overcurrent/surge current is generated.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to elements of each drawing, it should be noted that the same elements have the same numerals as possible even if they are indicated on different drawings. In addition, in describing the present invention, when it is determined that a detailed description of a related known configuration or function may obscure the subject matter of the present invention, a detailed description thereof will be omitted. In addition, a preferred embodiment of the present invention will be described below, but the technical idea of the present invention is not limited or limited thereto, and may be modified and variously implemented by a person skilled in the art.

1 is a block diagram schematically showing an entire system including an apparatus for controlling a power supply state according to a test scenario of a searcher according to an embodiment of the present invention.

As shown, the system for controlling the power supply state according to the test scenario includes a searcher 30, a power supply 20, a power supply state control device 10, and a user interface 40.

The seeker 30 is a device that detects or tracks a target, and provides a direction or position of a target necessary for calculating a guidance command to a guidance control device.

The power supply 20 supplies power required by the searcher, and may be powered off based on smart control of the power supply state control device 10 according to a test scenario.

The power supply state control device 10 includes a control unit 11 and a storage unit 13, and the storage unit 13 corresponds to a plurality of test items and a plurality of test scenarios according to the operating environment, and the searcher 30 The shape of the change in the current consumption required for this is recorded and stored as a profile pattern. In the profile pattern information, test scenario information and state information of the explorer 30 for each scenario are stored together. The control unit 11 generates a corresponding current consumption profile as a pattern through a predetermined number of repeated tests for each of the various test scenarios of the searcher, and records and stores it in the storage unit 13. In addition, a reference value for power supply control of the searcher 30 is set based on the profile pattern corresponding to each test scenario, and the power supply 20 that supplies power to the searcher is controlled using the profile pattern and the reference value. do.

Here, the current profile refers to a change in current consumed by the searcher over time, and the profile pattern refers to a specific form in which a change in current consumption appears over time. For example, in the case of a test scenario in which the searcher's operation mode is "Initialization -> Self-check -> Standby -> Search -> Track" in the order of time, there is vibration or no vibration in the test environment even at the same test time interval. In the case of a state or a vibration or preheating situation, the initial current value of the consumed current and the range of the rise or fall of the current flow curve according to the fluctuation of time are all different. That is, the shape in which the change in the current consumption of the searcher 30 appears is different, and the control unit 11 continuously accumulates the profile of the changed current in the searcher operation mode, calculates the average value thereof, and uses it to perform a specific test. Set the current consumption profile pattern according to the item and operating environment. Based on the current consumption profile pattern set as described above, when monitoring the current consumption of the explorer 30, it is possible to automatically detect a situation that exceeds the preset average value, that is, the profile pattern, and at this time, it is detected by considering all of the various test items and operating environment. It is possible to do.

In addition, even when the profile pattern needs to be updated, the status information of the searcher 30 can be input and updated at specific time intervals, and even when a peak current suddenly occurs at the time of self-inspection or transmission, the controller 11 does this. If the peak is not displayed in the normal pattern by flagging, the power supply to the searcher 30 may be cut off and a warning may be made. Conventionally, since the device for monitoring the current consumption of the searcher 30 cannot memorize all situations, the current to be consumed exceeds the threshold, resulting in a system error such as damage to the searcher 30. In the present invention, in order to prevent this, by setting a current consumption profile pattern and a reference value, and automatically detecting a situation exceeding the profile pattern by using the same, it is possible to automatically control the power supply state according to various test scenarios of the searcher.

On the other hand, among the test scenarios, the test items can be the distance of the target, the speed of the derivative, the angle, or the transmission power, and the operating environment is temperature, vibration, shock, altitude, humidity, salt spray, EMI (Electro-Magnetic Interference) or EMC (Electro-Magnetic Compatibility) can be considered.

The reference value set by the controller 11 may include a warning reference value and an automatic power control reference value. According to an embodiment of the present specification, the warning reference value may be set as a threshold of ±10% based on the profile pattern, and the automatic control reference value is a threshold of ±20% based on the profile pattern. It can be set by If, in the current test scenario, if the current consumption of the searcher 30 exceeds ±10% based on the profile pattern, the control unit 11 determines that the warning reference value has been exceeded and generates and outputs a warning signal. have. In addition, when the current consumption of the searcher 30 in the current test scenario exceeds ±20% based on the profile pattern, the control unit 11 determines that the automatic control reference value has been exceeded to prevent damage to the searcher 30. For this purpose, it is possible to control to cut off the power supply of the power supply 20.

Meanwhile, according to an embodiment of the present invention, the apparatus 10 for controlling the power supply state of the system may be configured to be connected to the user interface 40 so that the user can freely select test items and operation environments. Preferably, the user interface 40 may be configured as a GUI (Graphic User Interface). The user can monitor the status of the explorer 30 through a user interface such as a GUI, and in some cases, it is possible to set to disable the automatic control function of the power supply 20 of the power supply status control device 20. .

2 is a flowchart sequentially illustrating a process of setting a current consumption profile pattern of a searcher according to an embodiment of the present invention.

First, the control unit 11 measures a change type of the current consumption of the searcher 30 according to various test scenarios (S201).

Thereafter, the measurement is repeated a predetermined number of times (N) (S203), and the shape of the change in the measured current consumption, that is, the average value of the profile is calculated (S205). Here, the average value of the current consumption profile is set as a profile pattern and stored in the storage unit 13 (S207).

Thereafter, a reference value for controlling the power supply of the searcher is set based on the profile pattern (S209). The reference value may include a warning reference value and an automatic power control reference value. According to an embodiment of the present specification, the warning reference value may be set as a threshold of ±10% based on the profile pattern, and the automatic control reference value is a threshold of ±20% based on the profile pattern. It can be set by

3 is a flowchart sequentially showing a power supply state control process according to a test scenario of a searcher according to an embodiment of the present invention.

The control unit 11 monitors the current consumption of the searcher 30 for a specific test scenario (S301). Thereafter, the current consumption profile pattern corresponding to the specific test scenario stored in the storage unit 13 is compared with the monitored current consumption (S303).

As a result of the comparison, it is first determined whether the current consumption of the searcher 30 exceeds a warning reference value (S305). As a result of the determination, if the warning reference value is not exceeded, it is determined as a normal state, and the current consumption state of the searcher 30 is continuously monitored (S301).

If the determination result (S305), when the current consumption of the searcher 30 exceeds the warning reference value, it is determined whether it exceeds the automatic power control reference value (S307).

As a result of the determination (S307), if the automatic power control reference value is not exceeded, it is not in a dangerous state enough to damage the system, but it is determined as a level that may harm the system state, and a warning signal is output (S311). .

As a result of the determination (S307), when the automatic power control reference value is exceeded, it is determined as a dangerous state to damage the system, and the control unit 11 turns off the power so that the power supply of the power supply 20 can be cut off. Automatic control of is performed (S309).

4 to 8 are reference diagrams for explaining current consumption profile patterns according to various operation modes of the searcher.

FIG. 4 is a diagram illustrating a current consumption profile pattern of the searcher 30 when the operating environment of a test scenario is in a vibration or vibration-free state in an initial operation mode of the searcher 30.

In the initial stage, the vibration-free test refers to the anechoic chamber performance test, and assuming that the default upper limit of current is set to, for example, 3.5A, the warning threshold is 3.85A and- It can be set to 3.15A reflecting 10%. Therefore, when the load current value of the monitored searcher 30 exceeds 3.85A or falls below 3.15A, a warning signal may be output. In addition, when a load current in a range exceeding ±20% of the basic upper limit of 3.5A is sensed in a vibration-free test state at the initialization stage, the control unit may perform a procedure of automatically turning off the power supply.

In the vibration test in the initializing step, as shown in FIG. 4, a specific'+ offset' occurs in the profile of the current consumption compared to the vibration-free situation. Therefore, a current consumption profile pattern in consideration of a specific'+ offset' considering the vibration situation can be set in the current consumption profile pattern of the initialization mode corresponding to the vibration-free situation test item. In this case, the size of the offset may be applied differently according to the amplitude of the current profile pattern in the vibration situation, and the user can various options according to the operating environment such as the presence/absence of vibration and the size of vibration through the GUI 40. Can be set.

For example, if the test is conducted in a vibration condition to exclude initial failures in the initial stage of the searcher operation mode, the value obtained by adding 10% of the value of 3.5A, the basic upper limit of current consumption in the vibration-free condition, is added to the'vibration condition'. Set to the default upper limit of the initial stage current of ' In this way, based on the basic upper limit of the current to which a specific offset is applied, the warning and auto-off procedure for automatic power control can be tested by setting reference values as in the non-vibration state.

FIG. 5 exemplarily shows the current consumption profile pattern of the searcher 30 by moving or fixing the antenna when the operating environment of the test scenario is in a vibration-free state in the self-check operation mode of the searcher 30 It is a drawing. In this embodiment, it is possible to actively respond to a section in which the consumption current temporarily increases in consideration of the antenna driving time. In other words, when the antenna is not fixed and is driven (moved), a pattern in which the searcher consumption current temporarily increases at the time of driving, and the current consumption profile pattern does not increase at the driving time, or the estimated current profile pattern increases. Even if it rises beyond the range, it can be judged as an error. The driving time of the antenna can be estimated based on the gyro status, motor torque, and antenna driving command flag among the searcher status information.

Likewise, even when the driving of the antenna is not set, that is, in the case of the antenna fixation test scenario, if the current increases beyond a predetermined range of the current consumption profile pattern as illustrated, it may be determined as an error.

FIG. 6 is a diagram illustrating a current consumption profile pattern of the searcher 30 according to whether or not an operation (preheating) of a transmitter is set in a standby operation mode of the searcher 30.

In the above, after the self-check mode operation in which the antenna driving is set, it is possible to determine whether the transmitter is preheated in the standby mode. When the preheat start command of the transmitter is applied, a specific current consumption profile pattern is generated as shown. That is, a pattern in which a specific'+ offset' occurs within an initial specific time after the start command is shown, and a pattern in which a specific'+ offset' occurs even within a specific time in the late period, which is the time when the transmitter preheating is completed, is shown.

When the transmitter operation (preheat) is set in the test scenario, it is judged as an error if the current profile pattern does not rise in the early and late stages based on the time when the transmitter preheat command is applied. In addition, even when the reference value of the profile pattern is exceeded, it may be determined as an error.

Likewise, if the transmitter operation (preheat) is not set in the test scenario, that is, in the transmitter power off test scenario, it is judged as an error if it exceeds the set reference value of the illustrated current profile pattern.

7 is a diagram illustrating a current consumption profile pattern for each transmission output mode in an operation mode state of the searcher 30 by way of example.

In the search step, different current profiles are formed according to the transmission output mode setting. As shown, the size of the'+ offset' of Mode 1 and Mode 2 varies according to the setting of the transmission pulse width (duty) of Mode 1 transmission and Mode 2 transmission.

When the transmission output mode is set, a rising pattern of'+ offset' occurs within a specific time in the initial period after the transmission start command, and a rising pattern of'+ offset' occurs within a specific time in the later period after the transmission start command. The reason why a specific pattern of increasing consumption current occurs is that the complex factors of transmission power and antenna drive are reflected, and the event time when the rising pattern occurs can be estimated by monitoring power, transmitter status, gyro status, and motor torque. It is possible.

On the other hand, if the transmission power is not set, the search mode is omitted, a current consumption profile pattern is formed according to the simulated target tracking, and it is determined whether or not an error occurs accordingly.

8 is a diagram illustrating a current consumption profile pattern according to tracking maintenance or re-searching in a tracking operation mode state of the searcher 30 as an example. As shown, tracking or re-searching state information and current consumption profile patterns according to each situation are matched and stored.

When tracking is set, it is determined as an error when the reference value of the current consumption profile pattern is exceeded by referring to tracking status information.

When re-search is set, it is determined as an error when the reference value of the current consumption profile pattern is exceeded with reference to the re-search state information. In addition, even if the rising pattern does not appear at a specific point in time by referring to the rescan state information, it is determined as an error. The event timing at which the rising pattern appears can be determined by monitoring power, transmitter status, gyro status, and motor torque.
