Description

Device for detecting stationary state error in mobile terminal and its method {STABILITY FAULT DETECTION DEVICE AND METHOD THEREOF}

The present invention relates to a stationary state error detection device and a method thereof of a portable terminal, in particular, when the portable terminal is not normally mounted on a charging cradle, the stationary state error detection device of the portable terminal to detect this and notify the user And to a method thereof.

In general, portable terminals (wireless / wireless communication terminals, subway payment machines, etc.) that require charging are carried and used when used, but are mounted on a cradle (cradle) for non-use or charging. Here, the cradle is provided with a charging terminal, and the cradle with wired communication is also equipped with a communication terminal.

Charging and communication are performed only when the charging terminal of the portable terminal and the terminal of the cradle are physically connected correctly, and communication disconnection occurs when the communication terminal is not correctly connected in the terminal with wired communication.

Even when the terminal of the cradle, which is a cradle, and the terminal of the portable terminal are not correctly connected, the portable terminal does not recognize the above error condition. Accordingly, when charging is not progressed or wired communication is performed through the cradle, Disconnection occurs.

Therefore, a deferment state error detection technique for preventing such a connection failure situation and detecting a connection error has been proposed, and <Patent Document 1> below is an example of a conventionally proposed technique for detecting a deferment state error of a portable terminal. .

The prior art disclosed in <Patent Document 1> determines whether the mobile communication terminal and the charger holder are in contact by using a contact sensor, and when the mobile communication terminal and the charger holder are in contact with each other, operates a current measuring module to check the charging current and moves. When the charging current does not flow within a specific time between the communication terminal and the charger holder, it comprises a control unit for controlling to generate an alarm bell through the speaker.

Through such a configuration, an alarm bell is generated by providing an alarm bell when a current does not flow through the current measuring module, thereby preventing the mobile terminal from being charged due to a poor contact and causing inconvenience. Prevents charging from shortening battery life.

Republic of Korea Patent Publication 10-2007-0023337 (released February 28, 2007) (charger holder of the mobile communication terminal providing a contact failure alarm function and method)

However, the above conventional technology checks the flow state of the charging current when the connection is detected through the connection sensor, so if the charging current does not flow, an alarm is not recognized when the device is in contact with the device. Since there is a method of checking the malfunction of the device, it is impossible to detect a mounting error in a state where the holder and the charger are not physically contacted.

In addition, the prior art requires a number of sensors, such as a physical contact sensor, current detection sensor, and also has the disadvantage that a complex discrimination algorithm is required to determine the mounting error.

In addition, the portable terminal 20 includes an input unit 22 including a plurality of operation buttons for inputting a function, a screen output unit 21 for displaying charging information or traffic card usage information, etc. When the charging terminal is normally connected to the card processing unit 23 for processing card information, the communication unit 26 for communicating with the cradle 10 or for communicating with a server through a wireless communication module, and the cradle 10.

Referring to the operation of the mounting state error detection device of the portable terminal according to the present invention configured as described above in detail.

The portable terminal of the present invention may be a terminal used in various fields such as a wired / wireless communication terminal and a payment machine used in a history such as a subway, but the present invention will be described with reference to an embodiment of a payment machine used in a subway. However, the description of the embodiment of the present invention limited to the settlement machine is for convenience of description, and the present invention is not limited to the settlement machine, and the portable terminal capable of charging and communicating through a cradle is applicable. It would be obvious to those with ordinary skill in the sale.

In addition, prior to explaining the present invention, the general operation between the portable terminal 20 and the cradle 10, that is, the charging operation, communication operation, etc. is adopted in the present invention by adopting the general technology as it is, the specific operation thereof Will be omitted.

First, in order to detect a mounting error of the portable terminal 20, the portable terminal 20 is normally mounted on the cradle 10, and a reference position coordinate value setting function is input through the input unit 22.

When the reference position coordinate value setting function is input, the controller 24 drives the acceleration sensor unit 27 to detect the position coordinate value of the current position. As shown in FIG. 2, the acceleration sensor unit 27 includes three axes (X, Y, Z) sensors to detect information on each axis as position coordinate values. When the position coordinate value is detected in this way, the control unit 24 sets the reference position coordinate value range RP1 using the same and stores it in the internal memory. Here, the reference position coordinate value range RP1 refers to a range in which charging and communication are normally possible, although some mounting errors have occurred compared to the optimal mounting state.

Next, the controller 24 sets and registers the reference position coordinate value range RP1, and then determines the operation mode by checking the current use state of the portable terminal 20 in real time. In this case, the system automatically enters the sleep mode if it is not used for a predetermined time.

Herein, the operation mode may include an active mode for switching to a use state, a standby mode for maintaining a standby state, a sleep mode for switching to a sleep state, and a position coordinate value for detecting a stationary state error by automatically waking up at a predetermined period in the sleep mode. It may include a data collection mode to collect.

The controller 24 analyzes the use state and when it is determined that the portable terminal 20 is in operation, switches to the active mode to allow the portable terminal to be used normally. When it is determined, switch to the sleep mode.

In the sleep mode, the internal counter is used to check the passage of time and automatically wake up at a certain interval (for example, 10 seconds) to switch to the data acquisition mode. When switching to the data collection mode, the position sensor values are collected through the acceleration sensor unit 27, and the collected position coordinate values P are compared with the reference position coordinate value range RP1. As a result of the comparison, when the collected position coordinate value is included in the reference position coordinate value range, it is determined that the terminal is normally mounted on a cradle (cradle).

It is preferable to calculate about +/- 10% to the position coordinate value P and use it as a position coordinate value. That is, it is preferable to use X-axis coordinate value = X +/- 10%, Y-axis coordinate value = Y +/- 10%, and Z-axis coordinate value = Z +/- 10%.

On the contrary, if the collected position coordinate value is not included in the reference position coordinate value range, the collected position coordinate value P is compared with the preset mounting error detection range RP2 again. Here, the mounting error detection range (RP2) is a criterion for determining the mounting error, but refers to a range in which the terminal is mounted on the holder but is incorrectly mounted to prevent charging and communication.

As a result of the comparison, when the collected position coordinate value P is out of the mounting error detection range RP2, it is determined that the terminal is not mounted on the holder. At this time, the alarm for the mounting error does not occur.

In addition, if the collected position coordinate value (P) is included in the mounting error detection range (RP2), but the terminal is mounted on the holder, it is determined that the charging and communication is not made by incorrect mounting, the count is increased by "1". Let it be.

Then, the increased count value is compared with a preset reference value (for example, "3") to determine the mounting error, and if the count value is equal to or greater than the reference value, a final determination is made as the mounting error.

Subsequently, if it is determined that the mounting error is automatically switched to the standby mode, the alarm generator 28 is controlled to generate an alarm for the mounting error.

When an alarm occurs from the portable terminal 20, the user recognizes the mounting error and mounts the portable terminal 20 on the cradle 10 again.

As a result, even if the portable terminal 20 and the cradle 10 are not physically contacted, the presence or absence of a mounting error can be detected accurately and easily, and the user can normally detect the portable terminal 20 to the cradle 10 when an alarm occurs. By mounting, it is possible to prevent the charge is not made in the future to be disabled or disconnected wired communication in advance.

3 is a flowchart illustrating a mounting state error detection method of a portable terminal according to the present invention;

(a) The position coordinate value is read and set to the reference position coordinate value RP in a state where the portable terminal 20 is normally mounted on the cradle 10, and the controller 24 checks the operation state of the terminal and uses the state. (S101 ~ S103), (b) if the operation state of the terminal is determined to be non-use state, checking the non-use time and switching to the sleep mode if the state is not used for a predetermined time (S104). S105), (c) switching to the data collection mode by automatically waking up at a predetermined time after switching to the sleep mode by the controller 24 (S106 to S18), and (d) acceleration in the data collection mode. Collecting position coordinate values through a sensor unit, comparing the collected position coordinate values P with the reference position coordinate value range RP1, and determining a first placement error based on the comparison result (S109 ˜ S110) ), (e) the first stage As a result of determining the error, if it is determined that the abnormal mounting, comparing the collected position coordinate value (P) with a preset mounting error detection range (RP2) to finally determine whether the mounting error (S111), (f As a result of the determination of step (e), if it is determined that the final mounting error is included, switching to the standby mode and generating an alarm for the mounting error (S112 to S115).

In the step (d), (d1) collecting the position coordinate values through the acceleration sensor unit (S109), (d2) comparing the collected position coordinate values P and the reference position coordinate value range RP1 and collecting them. If one position coordinate value is out of the reference position coordinate value range, it is determined as a primary mounting error (S110).

In addition, the step (e) is (e1) when the primary mounting error is determined, if it is determined that the abnormal mounting, comparing the collected position coordinate value (P) and the preset mounting error detection range (RP2) Step (S111), (e2) when the result of the comparison, the collected position coordinate value (P) is out of the deferred error detection range RP2 is determined as non-fermented, and the collected position coordinate value (P) is If it is included in the deferred error detection range RP2, it is determined as a final deferred error, and the count (c) is increased (S112). (E3) The increased count (c) is a predetermined reference value ("3"). If exceeded, determining the final mounting error (S113).

Referring to the mounting state error detection method of the portable terminal according to the present invention configured as described above in detail.

First, in order to detect a mounting error of the portable terminal 20 in step S101, the portable terminal 20 is normally mounted in the cradle 10, and a reference position coordinate value setting function is input through the input unit 22. When the reference position coordinate value setting function is input, the controller 24 drives the acceleration sensor unit 27 to detect the position coordinate value of the current position. As shown in FIG. 2, the acceleration sensor unit 27 includes three axes (X, Y, Z) sensors to detect information on each axis as position coordinate values. When the position coordinate value is detected in this way, the control unit 24 sets the reference position coordinate value range RP1 based on this and stores it in the internal memory. Here, the reference position coordinate value range RP1 refers to a range in which charging and communication are normally possible, although some mounting errors have occurred compared to the optimal mounting state.

Next, the controller 24 sets and registers the reference position coordinate value range RP1 and then moves to step S102 to determine the operation mode by checking the current use state of the portable terminal 20 in real time. In this case, the system automatically enters the sleep mode if it is not used for a predetermined time.

The operation mode may include an active mode for switching to a use state, a standby mode for maintaining a standby state, a sleep mode for switching to a sleep state, and a position coordinate value for detecting a stationary state error by automatically waking up at a predetermined period in the sleep mode. It may include a data collection mode to collect.

The controller 24 analyzes the usage state, and when it is determined that the portable terminal 20 is in operation, moves to step S103 to switch to the active mode so that the portable terminal is normally used. Alternatively, the controller 24 analyzes the usage state as in step S104. As a result, if it is determined that the idle state is not used for a predetermined time or more, the process moves to step S105 to switch to the sleep mode.

In the state of switching to the sleep mode, as in step S106, the internal counter is used to check the passage of time while automatically waking up at a predetermined period (for example, 10 seconds) to switch to the data collection mode (S107 to S108). ).

When switching to the data acquisition mode, the position coordinate value is collected through the acceleration sensor unit 27 in step S109, and the position coordinate value P collected by moving to step S110 is compared with the reference position coordinate value range RP1. do.

When the collected position coordinate value P is included in the reference position coordinate value range RP1, it is determined that the terminal is normally mounted on the cradle (cradle), and the process moves to step S116 to initialize the count, and the above-described step Return to S102.

It is preferable to calculate about +/- 10% to the position coordinate value P and use it as a position coordinate value. That is, it is preferable to use X-axis coordinate value = X +/- 10%, Y-axis coordinate value = Y +/- 10%, and Z-axis coordinate value = Z +/- 10%.

On the contrary, if the collected position coordinate value is not included in the reference position coordinate value range, the process proceeds to step S111 to compare the collected position coordinate value P and the preset stationary error detection range RP2 again. Here, the mounting error detection range (RP2) is a criterion for determining the mounting error, but refers to a range in which the terminal is mounted on the holder but is incorrectly mounted to prevent charging and communication.

As a result of the comparison, if the collected position coordinate value P is out of the mounting error detection range RP2, it is determined that the terminal is not mounted on the holder. At this time, the alarm for the mounting error does not occur. If the collected position coordinate value P is out of the stationary error detection range RP2, the process moves to step S116 to initialize the count and returns to the above-described step S102.

In addition, if the collected position coordinate value (P) is included in the mounting error detection range (RP2), but the terminal is mounted on the cradle, it is determined that the charging and communication is not made due to incorrect mounting, go to step S112 and count Increases "1".

In step S113, the incremented count value is compared with a preset reference value (for example, "3") to determine the mounting error, and if the count value is equal to or greater than the reference value, a final determination is made as the mounting error.

Subsequently, if it is determined that the mounting error is moved to step S114 to automatically switch to the standby mode, and the process moves to step S115 to control the alarm generator 28 to generate an alarm for the mounting error.

When an alarm occurs from the portable terminal 20, the user recognizes the mounting error and mounts the portable terminal 20 on the cradle 10 again.

As a result, even if the portable terminal 20 and the cradle 10 are not physically contacted, the presence or absence of a mounting error can be detected accurately and easily, and the user can normally detect the portable terminal 20 to the cradle 10 when an alarm occurs. By mounting, it is possible to prevent the charge is not made in the future to be disabled or disconnected wired communication in advance.
