In addition, since the wired / wireless integrated controller of the DC motor according to the embodiment of the present invention can be used regardless of the types of the various DC motors 300, it can be replaced even if a failure of the mover control device occurs.

Also, the wired / wireless integrated controller of the DC motor according to the embodiment of the present invention can control the two together by using a single remote controller by interlocking the Steady using the wireless transceiver of the mover controller.

1 to 5, the wired / wireless integrated controller of the DC motor of the present invention includes a battery interface (not shown), a DC motor interface (not shown), and an integrated analysis controller 200.

The battery interface may be electrically connected to the battery 100 to provide the power stored in the battery 100 or receive power from the outside. Such a battery interface may consist of various ports that can be coupled to the battery 100 or an external power source.

The DC motor interface may be electrically connected to the DC motor 300 to provide a plurality of control signals or receive driving signals. That is, the DC motor interface includes an input terminal for receiving a driving signal generated by the DC motor 300 while being driven by the DC motor 300, and an input terminal for supplying power to the DC motor 300 or controlling the DC motor 300 And an output terminal for providing a plurality of control signals.

Here, the DC motor interface may include various input ports and various output ports so as to be connected to various DC motors 300 or a plurality of DC motors 300. Or the DC motor interface may be electrically connected to the DC motor 300 by being connected to a gender that can be connected to various types of DC motors 300. [

In addition, the DC motor interface may include an automotive terminal and a steady terminal.

The integrated analysis control unit 200 may include an analysis unit 210, a main control unit 220, a motor control unit 230, and a communication unit 260.

The analysis unit 210 may analyze the drive signal provided from the DC motor 300 through the DC motor interface. At this time, the analyzer 210 may analyze at least one of the voltage of the motor, the current of the motor, and the speed of the motor using the driving signal.

That is, the analyzer 210 senses and analyzes the voltage of the DC motor 300 provided to the DC motor 300 through the drive signal provided from the DC motor 300, or during the operation of the DC motor 300 The speed of the DC motor 300 can be sensed in real time using PWM (Pulse Width Modulation), and the current of the DC motor 300 provided to the DC motor 300 during the operation of the DC motor 300 can be sensed in real time .

For reference, PWM is a signaling system that can modulate the pulse width to exchange information. That is, since the control signal is transmitted to the motor as a PWM signal, it is preferable that the drive signal of the motor is also received as the PWM signal.

At this time, the drive signal of the motor can be supplied as a PWM signal (pulse signal) through a sensor (not shown) incorporated in the gear of the motor, for example, which receives the drive signal of the motor as a PWM signal. If the number of pulses is counted, the speed of the motor can be detected.

In the case of a general DC motor for precise control, it provides the drive signal of the motor to check whether the motor is in normal operation according to the motor control signal. By detecting the current and the speed of the DC motor at the same time, it is possible to detect the fault condition of the DC motor, which is judged to be a failure of the gear part when the current consumption is detected but the gear does not rotate.

According to the present invention, a drive signal of a motor can be supplied as a PWM signal (pulse signal) through a sensor built in a gear of a motor. When the number of pulses input in accordance with a gear ratio is counted, can do. If the speed of the motor according to the control signal is confirmed, the control signal can be sent so that the motor operates at the desired speed. That is, it can be used for general purpose. In other words, it is possible to provide a wired / wireless integrated control device of a DC motor capable of integrally controlling various kinds of DC motors with one control device.

For reference, the starting current can be minimized by gradually increasing the load current using PWM as shown in FIG.

In this way, the analyzer 210 can provide at least one of the voltage of the motor, the current of the motor, and the speed of the motor, which is generated by analyzing the sensed driving signal, to the main control unit 220.

Here, the analyzer 210 may analyze the voltage of the motor, the current of the motor, and the speed of the motor at the same time, and analyze the voltage of the motor, the current of the motor, and the speed of the motor, respectively.

Based on the analyzed data, the amount of current applied to the torque at the start of the DC motor is controlled to start.

The main control unit 220 may receive the analysis signal from the analysis unit 210 and may generate control data for controlling the DC motor 300. The main control unit 220 checks the voltage of the motor for the DC motor 300, the current of the motor, and the speed of the motor through the analysis signal provided from the analysis unit 210, The control data can be generated so that it can be operated with a value.

The reason for doing this is because the motor itself is influenced by the environmental factors or other devices operated by the motor may be affected by the environmental factors, , Motor speed increase and decrease, voltage increase or the like may occur. Therefore, it is preferable to vary the range of the control data or set value considering this.

In addition, among the above environmental factors, the ranges of the control data and the reference set values may be varied by assigning different priorities to each other or by changing the weights.

For example, if it is determined that the temperature can be most affected in determining the control data, the temperature can be given the highest priority or weighted to adjust the range of control data or reference setpoints based on that There will be.

Generally, electronic and electric elements constituting each device are closely influenced by temperature, so that the output value of the motor itself varies depending on the temperature change or the output value of other devices operated by the motor changes. Therefore, The output value can be stored in advance, and the control data can be applied in a different manner, thereby enabling operation or control in an optimum state.

The motor control unit 230 may receive control data from the main control unit 220 and may output a control signal for controlling the DC motor 300. The motor control unit 230 may include at least one relay.

The PWM unit 240 may receive control data from the main control unit 220 and change the pulse width according to a signal to be transmitted in order to control the DC motor 300. That is, the PWM unit 240 can control the load of the DC motor 300 by changing the pulse width according to a signal to be transmitted.

As described above, the PWM unit 240 controls the DC motor 300 while gradually increasing the load of the DC motor 300, thereby minimizing the operating current that can operate the DC motor 300.

The communication unit 260 may include a wireless communication unit 261 and a wired communication unit 262. The wired communication unit 262 may be electrically connected to at least one other integrated analysis control unit 200.

In addition, the wireless communication unit 261 can be connected to the wireless terminal using a communication means such as Bluetooth, Wi-Fi, or a small-output wireless device, which is a short-range communication device. In this manner, the user can control the plurality of integrated analysis control units 200 by using the wireless terminal. 2 and 5, when a plurality of integrated analysis control units 200 are connected to each other by using the wire communication unit 262, a user connects the plurality of integrated analysis control units 200 Can be easily controlled. This enables efficient control of two or more DC motors 300 through a single wireless transmitting / receiving unit using the interlocking port.

Thereby, a plurality of DC motors 300 can be controlled simultaneously. In addition, the output value of the DC motor 300 can be set for each product while monitoring the state of the DC motor 300 in real time through the wireless terminal using Bluetooth.

The new DC motor control system is compatible with all products by using a smart phone to control the motor regardless of each maker's motors and remote controller.

As shown in FIG. 5, a plurality of DC motors can be controlled by using a wireless terminal (smart phone). It is possible to control the plurality of control devices through the wireless terminal and the wireless communication by connecting the wired communication units to each other and enabling the interlocking port or wireless communication between the control devices.

Here, the wireless terminal may include all devices capable of installing and using an app such as a portable terminal device, a smart device, and a smart pad. By installing a DC motor control app which can control the DC motor 300, such a wireless terminal can easily control a plurality of DC motors 300 without a separate controller.

The DC motor control application stores data on various types of DC motors 300 and can display the status of the currently electrically connected DC motor 300. In addition, new information on various types of DC motors 300 can be updated in real time.

As described above, the integrated analysis control unit 200 according to an embodiment of the present invention analyzes the load value, the motor speed, and the voltage of the DC motor 300 so that the DC motor 300 can be used regardless of the types of the various DC motors 300 It can be used universally by reflecting the safe control value.
