Among the terms used in the present invention, 'tracking' may mean 'tracking' or 'transition'. However, it is not limited thereto. There is no substantial difference between 'period' and 'time', which includes the meaning of 'unavailable time'. Therefore, they are used in combination.

In the present invention, it is determined whether the apparatus is inspected or not, based on the time interval between when the apparatus is inspected and the time during which the apparatus is inspected, based on the voltage of the charge reservoir of the load-side power circuit to be energized with the power source If necessary, the user is informed by visual and auditory means so that he / she can receive the device check.

The power tracking system of the present invention can be used in an external state connected to the apparatus, or can be moved and carried and connected when necessary. Depending on the operation, a separate main controller or a networking computing system The information to be controlled or acquired can be shared and integratedly managed.

1 is an illustration of a power tracking system of a device according to an embodiment of the present invention.

The power supply tracking system (A) of the device according to the present invention includes a load power supply circuit (200) connected to the power supply (100) of the device and energized as shown in FIG.

The load power supply circuit 200 shown in FIG. 1 is an example in which the power source necessary for the activation of the control unit (MCU) or the notification device 240 is supplied with the regulated current of about 5 V through the decompression converter 210 . The voltage regulated by the decompression converter 210 is inputted to the power input terminal VCC of the control unit (MCU) and is distributed to the charge storage element 220. In FIG. 1, the charge storage element 220 is a C1 capacitor 230 that stores the charge of the current distributed from the voltage-reduction converter 210. FIG.

In the load power supply circuit 200 shown in Fig. 1, GND denotes a ground, R1 / R2 denotes a resistor, RY1A / RY2B denotes a relay, and CN1 denotes a charging connection terminal to which an external power source is connected.

The charge storage element 220 measures the time interval between the start of the device. As shown in FIG. 1, a C1 capacitor 230 (hereinafter, referred to as a "C1 capacitor" or a "capacitor") is a charge storage device 220, The charge storage element 220 may include a C1 capacitor 230 included in the load power supply circuit 200 or a battery. However, the charge storage device is not limited thereto, but may be any device capable of measuring the voltage drop between the timings of the device.

The control unit 250 calculates a non-operating period of the device through the voltage drop measurement of the charge storage device 220, determines whether the safety check of the device is required between the calculated unchecked period, and outputs a signal to the notifying device 240.

The voltage measurement value of the control unit 250 is compared with the comparison reference value to display a time, a time, a time or a time as a signal through a notification device, and performs system control on the dependent loads under the predetermined control condition . The period can be calculated by time, or the time can be calculated and output.

Here, the controller 250 may be an MCU (micro controller unit), an ECU, a microcomputer, or the like. The peripheral device may be interfaced with a signal processing module, an EPROM, a Flash-EPROM or an EEPROM, a monitoring module, a communication module, and the like, and may further include a diagnostic interface for self-diagnosis and error checking. However, it is not limited thereto, and the control system can be designed according to the characteristics of the apparatus.

The load power supply circuit 200 may include a charge connection terminal 260 for recharging the charge storage element 220 in a state where the long-term unexpected voltage of the apparatus is lowered.

The load power supply circuit 200 may include an RY1A relay 270 that can charge the charge storage element 220 in response to a control signal from the controller 250. [

The load power supply circuit 200 may further include a notification device 240. The notification device 240 may be configured to include an audio output device that outputs status information such as safety and inspection of the device as an alarm sound or a sound output device, and a device that visually displays the information. A display showing the inspection and safety status of the device, and a notification device outputting a buzzer or an alarm sound enable the user or manager to communicate and manage the situation information of the safety and inspection of the device.

The configuration of the control unit according to the embodiment of the present invention will be described in more detail as follows.

The control unit 250 sets the minimum allowable voltage value Vc_min. The setting criterion of the lowest allowable voltage value Vc_min is set to reflect the fluctuation amount of the voltage drop discharged from the charge storage element 220 during the period during which the apparatus is not in operation (including the off state of the power supply 100) And may be a predetermined voltage value. The minimum allowable voltage value (Vc_min) is a value that can be arbitrarily set by a user or an administrator to determine the number of unavailable days. May be determined in consideration of the characteristics of the device to be used and the characteristics and usage environment of the charge storage device 220 to be applied and may be input with an automatic setting value by configuring a program module in the control unit 250 as necessary.

The method of setting and setting the reference of the lowest allowable voltage value Vc_min is preferably such that when the minimum allowable voltage value Vc_min is artificially determined, the value of Vc_min is raised for a product having a short check period in consideration of the product characteristic of the device , And for a product having a long inspection period, the Vc_min value can be set as low as possible in accordance with different inspection cycles for each product.

The number of unavailable days of the device can be calculated in units of hours through the minimum allowable voltage value Vc_min set in the controller 250. [ For example, if the initial voltage value (discharge start voltage) of the charged storage element 220 that has been charged starts at 5 V and the discharge completion date (discharge end voltage in the case of a secondary battery) is 30 days, the total time (30 * 24) can be calculated as 720 hours. However, the total time required for discharge completion (discharge end voltage) calculated by the controller 250 may be varied depending on the type of the electric charge storage element 220 to be used and external environmental factors.

If the voltage input VSS input to the control unit 250 at the power on time of the device is compared with the initial voltage value of the initially measured charge storage device 220 and the voltage drop is read, It is possible to extract the voltage drop amount by dividing the drop amount by the relation of the voltage drop amount = discharge time, and determine the number of days (time) of operation of the device by the extracted voltage drop amount.

Therefore, if the current voltage read from the charge storage element 220 is larger than the set minimum allowable voltage value Vc_min, the controller 250 sets the reference of the lowest allowable voltage value Vc_min, A program for converting an unoperated period of the device by comparing with a voltage value Vc_min and storing the converted value as data and displaying the program, and may include tracking programs related to charge and error control.

In addition, the control unit 250 includes a program for analyzing a pattern of the usage period and the frequency of the device by converting the non-operation period or time of the device into data, thereby acquiring information on the durability, It can be used for performance improvement or for various purposes.

The operation of the power supply tracking system A of the apparatus according to the embodiment of the present invention will be described with reference to FIG.

When the user first turns on the power supply 100 for use of the device when the device is initially installed, the VCC / VSS operating voltage is input to the control unit 250 (usually about 5 V). The controller 250 is activated by the VCC / VSS operation voltage input to the controller 250 so that the voltage value of the C1 capacitor 230 as the charge storage element 220 can be checked.

If the current voltage Vc1 of the C1 capacitor 230 is greater than the minimum allowable voltage value Vc_min input to the controller 250, the current voltage Vc1 is compared with the initial voltage value that is the buffering voltage, (Power off time), the converted value is managed by storing it as data, and then it can be operated in normal operation.

On the other hand, when the current voltage Vc1 of the C1 capacitor 230 is equal to or smaller than the minimum allowable voltage value Vc_min input to the controller 250, Vc1? Vc_min, the operation stop command for the full load is transmitted, And outputs the result of the determination as an error signal, thereby being regarded as a device that has not been operated for a long period of time. This prevents a safety accident by stopping the full load operation of the device even if the user performs a series of operations.

The error output signal informs the user that an error code is displayed through the notification device 240, a buzzer sounds an alarm, or a device needs to be checked by voice guidance.

C1 capacitor 230 Current voltage can be initialized. The current voltage initialization of the C1 condenser 230 may charge the C1 capacitor 230 by outputting an output signal to drive the RY1A relay 270 in the control unit 250. [ Here, if Vc1 is less than or equal to Vc_min, the process of recharging and comparing with the initial voltage value is repeated.

However, considering that the current voltage is low in the measured voltage drop or that the discharge end voltage is set at about 90% of the normal voltage in the case of the secondary battery, the charging process for normal operation may be omitted as needed have. The system control method can be varied depending on the characteristics of the charge storage device used, including the C1 capacitor.

A method of controlling and tracking a power supply tracking system of an apparatus according to an embodiment of the present invention will now be described with reference to FIG.

2 is a flow chart illustrating operation and tracking control of a power supply tracking system of an apparatus according to an embodiment of the present invention.

The power supply tracking method of an apparatus according to an exemplary embodiment of the present invention may include setting a minimum allowable voltage value to the controller 250 during use of the apparatus or a device to be used, If the current voltage Vc1 is greater than the minimum allowable voltage value Vc_min at step S311, the current voltage of the charge storage element 200 is compared with the discharge start voltage of the previous initial voltage, (S310 to S312). Through this, it is possible to analyze the usage pattern of the device, and to acquire data information of the device at the same time.

The power supply tracking method of a device according to another embodiment of the present invention sets a minimum allowable voltage value Vc_min in the controller 250 in accordance with the device in use or the device to be used and then stores the electric charge read by the controller 250 If the current voltage Vc1 of the device 220 is greater than the minimum allowable voltage value Vc_min at S311, the current voltage Vc1 of the charge storage device 220 is compared with the discharge start voltage, (S315), the unused time obtained by calculating the current voltage (Vc1) of the charge storage element 220 after conversion is calculated as conversion data If the set time is exceeded (S316), the state can be controlled by a method of displaying the state as an error or a check notification (S317). The display method can be controlled by a method of displaying an error code according to the user's manual, a notification of checking the apparatus, and a method of displaying one or more of voice or buzzer alarms.

The power supply tracking method of the apparatus stops the load operation (S318) if the current voltage Vc1 of the charge storage element 220 is less than or equal to the minimum allowable voltage value Vc_min set in the controller 250 (S311) , And can be controlled in such a manner that the load operation stop state is displayed and notified (S319). The display method can be controlled by a method of displaying an error code according to the user's manual, a notification of checking the apparatus, and a method of displaying one or more of voice or buzzer alarms.

The power supply tracking method of the apparatus compares the current voltage Vc1 of the charge storage element 220 with the charge voltage Vc_chg after the controller 250 stores the data of the apparatus in a synchronized state. When Vc1 <Vc_chg (S313) (S314 to S315), and if it is not Vc1 <Vc_chg, the normal operation (S315) of the device can be performed (S310 to S315).

The power supply tracking method of the apparatus can be controlled by charging the charge storage element 220 in the standby state by discharging an output signal from the controller 250 in order to initialize the voltage of the charge storage element 220 in step S314.

The power supply tracking method of the apparatus displays and notifies (S317) if the unused time calculated by the conversion data of the current voltage Vc1 of the charge storage element 220 exceeds the set time (S316) May be controlled by a method of continuing the normal operation of the vehicle (S316).

The power supply tracking method according to an embodiment of the present invention can be performed in the order as shown in FIG.

When the power supply of the apparatus is on (S310), the current voltage Vc1 of the charge storage element 220 is compared with the minimum allowable voltage Vc_min set by the controller 250 (S311).

If it is determined that Vc1> Vc_min, that is, if the current voltage Vc1 is larger than the minimum allowable voltage Vc_min, the voltage of the present voltage Vc1 is compared with the initial voltage of the discharge start voltage, And converts the converted value into data (S312).

If the current voltage Vc1 of the charge storage element 220 is less than or equal to the minimum allowable voltage Vc_min as a result of the determination in step S311, the load operation is stopped (S318) The stop state is notified by notifying device 240 (S319). As a notification method, a manual error code, a maintenance notification display of the apparatus, and an alarm such as a voice or a buzzer may be displayed.

After step S312, the control unit 250 outputs a control signal to initialize the current voltage Vc1 of the charge storage element 220 to prepare the charge storage element 220 for charging.

The current voltage Vc1 and the charging voltage Vc_chg may be continuously compared with each other, and the charging operation or the operation of the apparatus may be controlled according to the comparison result (S313).

If it is determined in step S313 that the current voltage Vc1 and the charging voltage Vc_chg are Vc1 <Vc_chg, that is, if the charging voltage Vc_chg is larger than the current voltage Vc1, the RY1A relay driving and the charging start So that the user can use the device normally (S314 to S315).

If Vc1> Vc_chg, that is, if the charging voltage Vc_chg is smaller than the current voltage Vc1 as a result of the determination in step S313, charging is skipped and the device is immediately operated in step S315.

Subsequently, the unused time calculated by the converted data of the current voltage Vc1 of the charge storage device during or after the normal operation of the device is compared with the set time (S316). Here, the set time may be a set time value that is arbitrarily input, a value of a programmed execution execution time value, or a time value that is automatically updated and stored. However, it is not limited thereto.

If it is determined in step S316 that the unused time ≥ the set time, the status is displayed as an error code, a maintenance notification display of the device, a voice or a buzzer alert (S317), and if the unused time < And can be controlled to execute the operation.

According to the present invention, the power tracking system can be additionally installed in the power supply of the apparatus even in the absence of the power supply. If this leads to a restart without operating the equipment due to various reasons such as the long-term shipment due to the export of the equipment, the export of the equipment, or the long-term unavailability of the user's equipment, the electrical insulation of the electrical parts, It is possible to prevent the occurrence of safety accidents due to leakage, etc., and it is possible to analyze the device usage pattern of the user, thereby improving the product performance such as the durability of the device, the life of the device, There is an advantage.
