Hereinafter, the sensor module illustrated in FIG. 1 will be described in detail.

3 is a view schematically showing the external appearance of the sensor module shown in FIG. 1, and FIG. 4 is a block diagram showing an example of an internal configuration of the sensor module.

First, referring to FIG. 3, the sensor module 400 according to an embodiment of the present invention is located in a useful position in the vehicle, for example, in the form of a net and a leather pocket formed at the rear of the driver's chair. A fixing hook 402 is provided on the front of the case so that it can be attached and detached, so that the sensor information can be effectively obtained by being fixed to a net or a leather pocket at the back of the driver's chair through the fixing hook 402. In order to measure humidity, a plurality of air holes 404 are formed at the rear of the case.

Referring to FIG. 4, the sensor module 400 having an external appearance as illustrated in FIG. 3 basically provides a temperature / humidity sensor unit 450 to provide temperature information and humidity information in a vehicle to the terminal platform 300. ), And further includes a vibration sensor unit 420 to extend the life of the battery provided in the sensor module 400 as much as possible. That is, the sensor module according to an embodiment of the present invention is temperature information detected by the temperature / humidity sensor unit 440 only when the vibration sensor unit 440 detects vibration of the vehicle, that is, when the vehicle is in operation. And humidity information is transmitted to the terminal platform 300 according to a wireless communication method. Therefore, when the vehicle is not in a normal driving state, power consumption of the sensor module 400 may be minimized to extend the life of a battery (not shown) provided therein.

In detail, the sensor module 400 further includes a user input unit 410, a controller 430, and a wireless communication interface module 450 in addition to the vibration sensor unit 420 and the temperature / humidity sensor unit 440.

The user input unit 410 outputs an ON signal for driving the sensor module 400 in response to a user's manipulation.

In response to the ON signal from the user input unit 410, the vibration sensor unit 420 starts to detect the vibration of the vehicle, that is, whether the vehicle starts to be driven. In the absence of the vibration of the vehicle, that is, the vehicle is in a stopped state. In the case where the vibration of the vehicle is weak, that is, when the vehicle is slowing, the first vibration value is output, and when the vehicle starts to drive at a normal speed, that is, a predetermined speed value or more, the second vibration value is output. .

The controller 430 is a kind of CPU, and is basically connected to the respective building blocks 410, 420, 440, and 450 constituting the sensor module 400 to control their overall operations. In this case, when the controller 430 receives the first vibration value from the vibration sensor unit 420, the controller 430 controls each of the building blocks 410, 420, 440, and 450 in the sleep mode. Here, the sleep mode may be defined as a state in which a signal line connecting each component block is in an operating state but no control or information is transmitted through the signal line. For example, in this sleep mode, the temperature / humidity sensor unit 440 and the wireless communication interface module (I / F) 450 do not receive any control or information from the control unit 430 to perform their respective functions. . Therefore, in this sleep mode, since the wireless communication function, which occupies the largest portion of the power consumption of the sensor module 400, does not operate, power consumption of the sensor module 400 can be minimized.

On the other hand, when the vibration sensor unit 420 detects that the vehicle is driving normally, an interrupt signal, that is, a second vibration value is generated and output to the controller 430, and the controller 430 responds to the second vibration value. Each of the building blocks 410, 420, 440, and 450 constituting the sensor module 400 is switched from the sleep mode to the wake up mode. After this point in time, the control unit 430 starts to transmit any control or information to each of the component blocks. For example, when the controller 430 receives a second vibration value indicating that the vehicle is driving normally from the vibration sensor unit 420, the controller 430 instructs the operation of the temperature / humidity sensor unit 440 and the wireless communication interface module 450 to start. The operation start signal DS may be output, and the temperature / humidity sensor unit 440 and the wireless communication interface module 450 respectively initiate the sensing operation and the wireless communication operation in response to the operation start signal DS.

The temperature / humidity sensor unit 440 includes a temperature sensor and a humidity sensor, initiates operation in response to the operation start signal DS from the control unit 430, and displays the current temperature at a useful position in the vehicle and Humidity is detected, and the detected temperature and humidity are converted into electrical and electrical values, which are output in real time.

The wireless communication interface module 450 starts operation in response to the operation start signal DS from the control unit 430, and transmits the temperature value / humidity value from the temperature / humidity sensor unit 440 to the wireless communication scheme. According to the terminal platform 300 in real time.

Sensor module 400 consisting of these configurations can be provided with a fixing hook that can be detachable to facilitate installation and storage in the form of a net and leather pocket on the back of the driver's chair, The relevant sensor information can be effectively acquired in a fixed state in the leather pocket.

In addition, the sensor module 400 basically includes three sensors as a temperature sensor, a humidity sensor, and a vibration sensor. The temperature sensor and the humidity sensor may be designed separately, but in consideration of the size of the sensor module, It is preferable to implement a complex sensor, the vibration sensor is implemented separately. At this time, the vibration sensor provided in the sensor module, as described above, is used for effectively controlling the wireless communication function, it is possible to extend the life of the battery which is a limited resource provided in the sensor module 400 to the maximum. That is, when the vibration sensor detects a vibration corresponding to the normal driving of the vehicle, the sensor module 400 is switched from the sleep mode to the wake-up mode, thereby minimizing the power consumption while the vehicle is not driving to extend the life of the battery. can do.

Subsequently, the control unit 430 (or the CPU) of the sensor module 400 of FIG. 4 wakes up not only itself, but also all other component blocks in the sensor module 400 from the sleep mode, that is, in response to the interrupt occurring. Switch to the ON state. When the controller 430 of FIG. 4 switches to the wake-up mode, generates an operation start signal in response to an interrupt from the vibration sensor unit 420, and transmits the signal to the temperature / humidity sensor unit 440 of FIG. The humidity sensor unit starts operation in response to the operation start signal (S550). At this time, the wireless communication function of the wireless interface module 450 of FIG. 4 is also turned on (S560).

Subsequently, the wireless interface module 450 of FIG. 4 having the wireless communication function activated (ON) converts the temperature / humidity value received from the temperature / humidity sensor unit 440 of FIG. 4 into a transmission format based on a wireless communication transmission standard. It converts and wirelessly transmits to the terminal platform (300 of FIG. 1). After performing this operation, the controller returns to the sleep mode and waits at a low power until the next vibration value is detected.
