Description

[0001] Energy harvesting sensor module [0002]

The present invention relates to a sensor module which is capable of energy harvesting and which can be easily installed and moved. In detail, the sensor module can measure information on the temperature, humidity, etc. of the real-life space and communicate with the air conditioner or the like using the measured information to manage the temperature and / or humidity of the space in which the sensor module is installed To a sensor module.

There are a lot of devices that need to detect the operating state, not just outside the room. For example, it is necessary to monitor whether the device is performing normal / abnormal or operation as instructed. The device may be sensed by a sensor module in an environment adjacent to the device.

The device can perform its operation while emitting energy. The emitted energy may be various types of energy such as heat, electricity, and light. The sensor module may be operated by harvesting various types of energy emitted from the device. Of course, the sensor module may use energy collected from other external objects, for example, solar energy, or external light, as an energy source, rather than energy directly emitted from the device. This can be referred to as an energy harvesting sensor module.

The energy harvesting technique refers to a technique of harvesting small energy that is routinely discarded or not used and converting it into usable electric energy, and vibration, human motion, light, heat, and electromagnetic waves can be used as a main energy source.

An example of such a device is a showcase. Of course, the device is not limited to a showcase.

The showcase is a facility that allows customers to display refrigerated or frozen products at stores and stores. The showcase can be configured as an open front.

Unlike a refrigerator in an adiabatic environment, a showcase with an open front needs to be more precise and instantaneous in the temperature of the display space.

In addition, the showcase is equipped with shelves of several stages. The temperature at which the food stored on the shelf can maintain the best preserved state differs depending on the type of the food. And, the display position of the food can be changed according to various situations, not the food of the same kind is always displayed for each section of the showcase.

The conventional showcase has a problem that the manager has to directly check the temperature and humidity conditions. Such a showcase maintenance approach is very difficult to precisely and immediately adjust the temperature of the display space.

Current household appliances are equipped with communication modules to provide various smart functions other than the original functions of household appliances. Various information can be obtained from the outside using the communication module.

With this in mind, a network-type showcase management system has been spreading in which a wired network is configured in a showcase, a wireless network is configured, and an administrator can manage the network in a server at one time.

However, in the case of applying the wired network among these conventional systems, a separate construction is required for network construction, and there is a problem that the wiring work must be repeated every time the showcase is added or deleted or the location is changed. In addition, even when a wireless network is applied, wiring work for supplying power to the wireless network equipment has been inevitable. Therefore, there is a need for a sensor module capable of wireless communication capable of independently supplying power.

In addition, the conventional showcase network structure has to control the entire showcase with a single temperature and humidity. This limits the ability to display foods in similar showcases that require similar temperatures. Therefore, a sensor module that is easy to install and small in size is needed so that temperature and humidity can be detected in each space in the showcase.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

It is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to inform.

FIG. 1 is a perspective view showing an outer appearance of a sensor module according to an embodiment of the present invention from above, FIG. 2 is a perspective view showing an outer appearance of a sensor module according to an embodiment of the present invention from the bottom, FIG. Fig. 5 is an exploded view showing a part of the configuration of the sensor module according to Fig.

1, a sensor module 1 according to the present invention includes a case 20 forming an outer appearance, a window 30 coupled to the case 20, , And a button (40) coupled to the case (20) to form an upper portion of the outer tube.

The case 20 may form an appearance of the sensor module. The case 20 may have various shapes such as a cylinder, a quadrangular prism, and a triangular prism. For example, the case 20 may be formed in a cylindrical shape extending in one direction. In addition, the case 20 may have a triangular prism shape having a triangular bottom surface in order to optimize the incidence area of light. In addition, by deforming each corner point formed by the triangular column into a rounded shape, the user can easily grasp the sensor module 1 and further improve the esthetics of the sensor module.

The case 20 according to the embodiment of the present invention will be described on the basis of a triangular prism.

The case 20 is provided with a face (hereinafter referred to as an open upper face of the case) formed along the periphery of the upper end of the case to which the button 40 is disposed and a base 10 (Hereinafter referred to as the lower surface of the case) which is formed along the periphery of the lower end of the case arranged to be joined together can be opened. That is, the case 20 can be formed so that the upper side and the lower side are opened.

1, the upward direction or the upward direction can be understood as a direction toward the button 40 from the center of the case 20, and the downward direction or the downward direction can be understood as a direction toward the base 10 from the center of the case 20 Direction.

In addition, the case 10 may form a window mounting space 22 for installing the window 30. That is, the window mounting space 22 may be formed on one side of the case 20. For example, the window mounting space 22 may be formed as a rectangular open space on one side of the case 20. The window mounting space 22 may be formed by cutting out a part of one surface of the case 20 in a shape corresponding to the window 3. [

Further, the case 20 can be formed to have at least three walls. Here, a circuit board to be described later is placed adjacently, and the corresponding wall can be called a first wall. Likewise, a secondary battery to be described later is placed adjacent, and the corresponding wall can be called a second wall, and a harvester to be described later can be placed adjacent to the corresponding wall to be called a third wall.

The window 30 is installed in the window mounting space 22 and may be formed to allow light to be incident on the sensor module 1. The window 30 may be formed of a transparent material. Therefore, the sensor module 1 can easily receive the light irradiated to any space. In addition, the light may be provided by natural light, a light emitting device, or the like existing in a space where the sensor module 1 is installed.

Hereinafter, the space where the sensor module 1 is installed is called a use space. Light existing in the utilization space is incident on the window 30 and reaches the harvester 58 to generate energy. In addition, the window 30 may protect the harvester 58 from the external environment.

The base 10 may be coupled to the case 20 so that air can flow. That is, at least a part of the space between the case 20 and the lower side of the case may be opened. For example, the base 10 may be spaced apart from the lower end of the case 20 and may engage with the inside of the case 20 through a hook 18 formed on the base. Here, the spacing direction of the base 10 can be understood as at least one of a center direction and a longitudinal direction of the case 20.

The air in the utilization space can flow into or out of the space formed between the case 20 and the base 10. [ Here, the interspace may be understood as an open space excluding the hook 18 and a portion where the inside of the case is coupled. The space between the case 20 and the base 10 is called a lower flow space 4.

The base 10 may have various shapes. For example, the base 10 may form an upper surface and a lower surface of the base 20 in a shape corresponding to a shape formed around the lower end of the case 20, that is, an open lower virtual surface of the case 20 have. In this case, the case 20 and the base 10 form a sense of unity, and the sense of beauty of the sensor module 1 can be improved.

In addition, the base 10 may have a truncated triangular shape. When the end has a truncated triangular shape, the side surface including the edge connecting the upper surface and the lower surface of the base may be formed as a curved surface that curves inward to have a certain curvature. In addition, the triangular shape of the top and bottom surfaces of the base 10 can be formed to have a rounded shape so that the vertexes have a certain curvature.

The button (40) can be coupled to the case (20) so that air can flow. That is, at least a part of the space between the case 20 and the upper side of the case may be opened. For example, the button 40 may be spaced apart from the upper end of the case 20 and may engage with the inner side of the case through a connection ring 42 formed at the lower edge of the button 40. Here, the spacing direction of the buttons 40 can be understood as at least one of a center direction and a length direction of the case 20. For example, the button 40 may be formed to be smaller than the open top surface of the case 20 and coupled with the case 40, thereby securing a space for air flow. That is, the button 40 may be formed in various shapes.

The air in the use space can flow into or out of the space formed between the case 20 and the button 40. [ Here, the interspace may be understood as an open space excluding a part where the connection ring 42 and the inside of the case are coupled. The space between the case 20 and the button 40 is called an upper-phase space 3.

That is, the gas in the utilization space flows into the upper flow space 3, flows out into the lower flow space 4, or flows into the lower flow space 4 and flows out into the upper flow space 3, It can flow through the space inside the module. Therefore, the sensor module 1 can detect the temperature, the humidity, and the like using the gas in the installed space. (See arrows in Figs. 1 and 2)

2 and 3, the case 20 includes a front case 21 on which a window mounting space 22 is formed, a first auxiliary case 23 coupled with the front case 21, And may include a case 24.

The front case 21 may be formed on one side of the case 20 to provide an open space. The first auxiliary case 23 and the second auxiliary case 24 may extend to both sides of the front case 21 to form a pair. For example, one end of the front case 21 may be coupled to the first auxiliary case 23, and the other end may be coupled to the second auxiliary case 24. The first auxiliary case 23 and the second auxiliary case 24 may be coupled to the side end portions of the front case 21 that are not engaged with each other to form a triangular prism.

Each corner of the triangular column formed by the case 20 can be rounded to have a certain curvature. In this case, an auxiliary case having a curved surface is further coupled to the side end portions where the front case 21, the first auxiliary case 23, and the second auxiliary case 24 are coupled to each other to form a rounded triangular pillar .

The front case 21 is formed with a window mounting space 22 and can be coupled to the window 30. That is, the window 30 may be provided in the front case. Therefore, the harvester to be described later can be placed inside the window 30. Also, the front case 21 can be understood as a concept corresponding to the above-mentioned third wall. On the other hand, the position where the window mounting space 22 is formed is not limited.

The first auxiliary case 23 can be understood as a case 20 corresponding to a circuit board to be described later. This can be understood as a concept corresponding to the above-mentioned first wall.

The second auxiliary case 24 can be understood as a case 20 corresponding to a secondary battery to be described later. This can be understood as a concept corresponding to the above-mentioned second wall.

The case 20 may further include a skirt 25 for shielding a part of the opened upper surface. The skirt 25 may extend along the center of the case 20 along the upper end of the case 20. At this time, the extension length may be selected to be an appropriate length so that all of the upper surface of the case 20 is not shielded. Therefore, the upper surface of the case 20 can be formed to maintain the open state. That is, even if the button 40 is engaged with the skirt 25, the upper space 3, which is the flow path of the air, can be maintained.

The skirt 25 may form a bending surface that curves inward from the periphery of the upper surface of the case 20 toward the center of the case so as to provide a more smooth air flow path. In addition, the skirt 25 may form a seating surface so that the button 30 can be seated when the user presses the button 40. For example, the seating surface may extend horizontally from an end of the bending surface. The skirt 35 having such a shape has the effect that the size of the sensor module 1 can be minimized by forming the button 40 at a lower position than the upper end of the case 20. In addition, the sense of unity of the sensor module 1 can be further improved.

When the button 40 is moved downward by the pressure, the button 40 can be restrained from moving beyond a predetermined length by being supported by the bending surface and the seating surface of the skirt 25. That is, the maximum downward movement distance of the button 40 can be understood as a length in which the button 40 reaches and abuts on the skirt 25. Therefore, since the skirt 25 supports the button 40 to be pressed, there is an advantage that the risk of breakage of the device due to the pressing force is prevented.

The skirt 25 may include a receiving groove 26 for engaging with the button 40. The receiving groove 26 may be provided in the case 20 so that a connecting ring 42 to be described later may be allowed to move along at least the extending direction of the case 20. [

The position, number, and shape of the receiving groove 26 are not limited. However, the air passing through the inside of the sensor module 1 may be blocked due to the blocking of the flow path due to the engagement of the button 40 with the skirt 25. Therefore, it is preferable that the receiving groove 26 corresponding to the joint portion of the skirt 25 and the button 40 is formed so as to secure a flow path of air. For example, the receiving groove 26 may be recessed on the inner surface of the skirt 25. Or may be formed to project downward from the seating surface of the skirt 25. At this time, it is desirable that the size of the receiving groove 26 is formed to be a relatively small size that can minimize the interference of the air flow. Therefore, the air passing through the interior of the sensor module 1 can maintain the flow path to the upper flow space 3, thereby achieving air circulation.

On the other hand, when the user operates the button 40, the button 40, which has reached the skirt 25 by the user's pressing, can be returned to the original position by receiving the restoring force by a resilient device such as a spring. At this time, the connection groove 42 of the button 40 and the connection groove 42 of the button 40 to be described later can be engaged so that the button 40 can be prevented from being released by the elastic force.

The skirt 25 may further include a substrate rib 27 for fixing the circuit board 50. The substrate rib 27 may be provided on the lower surface of the skirt 25 to the inside of the case 20. That is, it can be installed on the bottom surface of the seating surface.

Since the sensor module 1 is small, the sensor module 1 can be easily rotated by the user and can be installed in various directions according to the installation environment. Therefore, it is possible to prevent the breakage and improve the stability of the sensor module 1 by fixing the circuit board to hold it in both the upper and lower directions. In addition, the operation reliability of the sensor module 1 can be improved through the stable fixing of the circuit board 50.

The button 40 may include a connection ring 43 formed to be able to engage with the skirt 25 and a pressing surface 41 constituting the upper surface of the button 40.

The linking ring 43 may be provided at the rim of the button 40. Specifically, the button 40 may protrude outward from a lower end of the button 40 or a lower edge of the button 40. Therefore, the connecting ring 43 can be engaged with the receiving groove 26 of the skirt 25. [ In addition, the connection ring 43 and the receiving groove 26 may be coupled so that the button 40 can be moved up and down.

The linking ring 43 may have various shapes. For example, the linking ring 43 may be bent downward to form a curvature from the lower end of the button 40 to the end of the receiving groove 26. The connecting ring 43 having a bent shape is seated on one surface of the connecting ring 43 which is formed by being recessed in the receiving groove 26. The end of the connecting ring 43 is inserted into the receiving groove 26 So that the button 40 can be moved up and down in a limited manner.

The pressing surface 41 can be formed in various shapes and materials. For example, the pressing surface 41 can be made of transparent plastic, rubber or the like to ensure durability, and can be formed so that user's contact can be easily performed.

The button 40 may include a light emitting device 47 such as an LED. The light emitting device 47 is positioned adjacent to the button 40 and can emit light in accordance with the operation state of the sensor module 1 to display the operation state. For example, when the user presses the button 40, the color of the pressing surface 41 may be changed by providing the light emitting element 47 and the sensing sensor inside the button 40. [ In this case, the pressing surface 41 may be formed of a transparent material. In addition, when the user presses the button 40 to connect wireless communication, the color of the pressing surface 41 can be changed. In addition, the light emitting device 47 can be configured to operate only when the button 40 is pressed and power is connected to the circuit board. In addition, the light emitting device 47 can operate the display state differently depending on the number of times the external force is applied to the button 40. That is, the light emitting device 47 can display a connection state of the wireless communication unit and the external gateway, and on / off state of the power source. Accordingly, the user can visually check the operating state of the sensor module 1 through the color change of the button 40, which is convenient, and has an advantage that the esthetics of the product can be improved.

The button (40) may further include a switch (45). The switch 45 may convert the operation of the button 40 into an electrical signal and transmit it to the circuit board 50. That is, the switch 45 may be interlocked with the operation of the button 40, and may be interlocked with the circuit board 50. Accordingly, the button (40) can press the switch (45) by deformation or movement along the extending direction of the case (20). In one example, the switch 45 may be a dip switch.

The switch 45 is connected to the circuit board 50 and can perform various operations of the circuit board 50 through electrical signals according to the number of times the button 40 is pressed. For example, when the button 40 is pressed once, a signal can be transmitted to connect the power source to the circuit board 50. When the button 40 is pressed twice, the wireless communication unit of the circuit board 50 is paired with an external gateway. The signal can be transmitted. A signal for releasing the paying ring can be transmitted when it is pressurized three times, and a signal for disconnecting the power supply of the circuit board 50 can be transmitted when it is pressurized four times. As another example, when the user presses the button 40 for the first time, the power of the circuit board 50 is turned on, so that power can be supplied from the secondary battery. When the user presses the button 40 again The power supply can be turned off and the power supply to the circuit board 50 can be stopped. In another example, the light emitting element is interlocked with the light emitting element. When the button 40 is pressed only once, a sensor unit for sensing temperature and humidity can be operated, and the light emitting device can be displayed in any one color. After the light of the light emitting device is turned on, the operation of the sensor unit can be controlled while operating the button 40 a number of times. When the button 40 is pressed twice, the wireless communication unit performing wireless communication can be operated, and the light emitting device can display the preparation of the wireless communication unit control operation with another color. After the light of the light emitting element is turned on, various operations of the wireless communication operation can be controlled by operating the button 40 again various times. That is, the operation of the sensor unit and the wireless communication unit can be controlled according to the operation of the button 40. In other cases, the light emitting device 47 and the button 40 may be interlocked with each other to control the circuit board 50 in various ways according to the number of times the button is pressed.

The button 40 may include an elastic member such as a spring. The elastic member may provide restoring force to return the button 40 to an existing position after the button 40 is pressed. For example, when the user presses the pressing surface 41 to apply pressure, the button 40 turns the power of the circuit board 50 on via the switch 45, and then returns to the original position When the user presses the pressing surface 41 again by pressing the button 40, the button 40 can be returned to its original position after powering off the circuit board through the switch 45.

The sensor module 1 can achieve power supply connection and wireless communication connection of the circuit board 50 only by a simple operation of pressing the button 40 by the user.

The base 10 may include a support base 11 constituting a lower portion of the base and an installation base 12 constituting an upper portion of the base.

The support base 11 can be formed in various shapes. For example, the support base 11 may have a truncated triangular shape. In addition, it can have a rounded shape so that side and apexes have curvature. At this time, the lower surface of the support base 11 is wider than the upper surface and can be understood to be equivalent to the bottom surface of the support base 11. [

Hereinafter, the support base 11 having a truncated triangular shape will be described.

The bottom surface of the support base 11 may be composed of a support surface 13 and a rising surface 14.

The support surface 13 may be formed flat along the lower end of the support base 11 so as to contact the outer surface for stable support when the sensor module 1 is installed upright. Therefore, the support surface 13 can stably support the upright sensor module 1 from below. For example, the sensor module 1 may be mounted on a desk or the like in an indoor space. At this time, the sensor module 1 may be installed on the desk base so as to abut the support base 11 constituting the lower portion of the base 10, Upright. That is, the support surface 13 formed on the bottom surface of the support base 11 abuts against the desk, and the sensor module 1 can be stably supported. In this way, when the base 10 supports the upright sensor module 1, the sensor module 1 can be referred to as a desk-top sensor module 1. On the other hand, the case where the sensor module 1 is installed on a wall surface of a showcase or the like can be referred to as a wall-mounted type sensor module 1. The wall-mounted type sensor module 1 can be installed such that the base 10 and the button 40 are in a horizontal direction, that is, the longitudinal direction of the sensor module 1 is horizontal to the wall surface.

The raised surface 14 may be recessed upward so that the bottom surface of the support base 11 is not in contact with the outer surface. Here, the external surface can be understood as one side of any object or space contacting the supporting surface 13 when the desk-top type sensor module 1 is installed. Thus, the raised surface 14 may be spaced from the outer surface.

The elevating surface 14 may form a device connecting hole 15 for guiding the external device and the sensor module 1 to be stably connected. For example, the device connection hole 15 may be formed such that a USB is inserted. At this time, the shape of the device connection name 15 can be formed so as to correspond to the USB device. Therefore, it is possible to guide the USB port and the USB device of the circuit board, which will be described later, to be stably connected through the device connection hole 15. [

In addition, the elevating surface 14 may form a reset hole 16 for guiding the user to press the reset button of the circuit board. By way of example, the user can insert a tool into the reset hole 16 and press the reset button of the circuit. In this case, the sensor module 1 can be initialized.

A circuit board to be described later may be mounted on the base 10 such that a USB port and a reset button provided on the circuit board correspond to the device connection hole 15 and the reset hole 16. [

Since the elevating surface 14 is formed so as not to come into contact with the outer surface even in the case of the desk-top type sensor module 1, it is possible to protect the device connecting hole 15 and the reset hole 16 from breakage, There is an advantage to be able to do.

The mounting base 12 may extend from the upper end of the supporting base 11. [ In detail, the installation base 12 may be formed to extend upward along the rim of the upper surface of the support base 11. Here, the upward direction can be understood as the height direction of the base 10 or the direction from the base 10 to the button 40. [

Since the mounting base 12 is formed to extend upward along the upper surface of the support base 11, a space can be formed therein.

The internal space of the installation base 12 is called an installation space 17. The upper surface of the support base 11 forms the bottom of the installation space 17 and the installation base 12 can form the outer wall of the installation space 17. [

The mounting base 12 may include a hook 18 engageable with the inside of the case 20. The hook 18 may protrude outward from one side of the mounting base 12. [ For example, when the installation base 12 has a triangular prism shape, the hook 18 may be formed in a projected shape on each outer surface. That is, it may be formed to extend vertically outward from the upper end of the outer surface of the installation base 12. [

The hook 18 can be engaged with the inside of the case 20 through a latching operation. In detail, the mounting base 12 is inserted into the case 20, and the hook 18 protruding outward from the mounting base 12 in the inserting process presses the inner side by the case 20 Can receive. Therefore, the upper portion of the hook 18 can be inclined in the pressing direction of the caisses 20. [ At this time, the hook 18 can also press the inner surface of the case to return to the original state by the elastic force. Thereafter, the hook 18 reaches the groove formed in the inner side surface of the case 20, and the hook can be engaged by the elastic force of the hook. This process can be understood as a hooking operation of the hook. Therefore, the case 20 and the base 10 can be coupled through the hook 18.

The hook 18 may be formed of a material having an elastic force for the latching operation. For example, the hook 18 may be made of a material such as plastic.

In addition, a groove may be formed on one surface of the mounting base 12 at a position where it abuts both ends of the protruding hook 18. In one example, the grooves may be formed at two points of the mounting base 12 abutting both side ends of the hook 18. At the two points, the groove may be formed so as to be concave downward from the upper end of the mounting base 12. [ Therefore, since the hook 18 can be easily tilted by pressing the case 20 through the groove, the hooking operation can be facilitated.

The hook 18 may include a main hook 18a, a first auxiliary hook 18b, and a second auxiliary hook 18c. That is, the hooks 18 may be formed in a plurality of hooks depending on the shape of the mounting base 12.

The main hook 18a can be engaged with one surface of the case 20 forming the window mounting space 22. [ For example, the main hook 18a can engage with the front case 21. In detail, the main hook 18a can be engaged with the recess formed in the inner surface of the front case 21 through the engagement of the hook.

The main hook 18a may include a harvestor accommodating portion 19 capable of mounting the harvester. The harvest receiving portion 19 can be formed on the upper surface of the main hook 18a.

The first auxiliary hook 18b may be engaged with one surface of the case 20. [ For example, the first auxiliary hook 18b may be engaged with the groove formed in the inner side surface of the first auxiliary case 23 through the engagement of the hook. That is, the first auxiliary hook 18b may be regarded as a hook formed at a position nearest to the circuit board 50 installed in the installation space 17.

The second auxiliary hook 18c can be engaged with one surface of the case 20. For example, the second auxiliary hook 18c may be engaged with the groove formed in the inner side surface of the second auxiliary case 24 through the engagement of the hook. The second auxiliary hook and the second auxiliary case can be understood as a hook and a case formed at a position nearest to the secondary battery 57 mounted in the installation space 17. [

FIG. 4 is an exploded view showing a part of the structure mounted on the base of the sensor module according to the embodiment of the present invention.

Referring to FIG. 4, the sensor module 1 may further include a circuit board 50, a secondary battery 57, and a harvester 58 mounted on the base 10.

The circuit board 50 may be mounted on the base 10 and placed in the installation space 17. [ When the power source is connected to the circuit board 50, the circuit board 50 senses the temperature and humidity of the installation space, and performs wireless communication to transmit sensed information. In addition, the circuit board 50 may be placed in the inner space of the case 20 corresponding to the first wall. The circuit board 50 may be mounted on the upper surface of the support base 11 by inserting the circuit board 50 along the inner surface of the installation base 12 on which the first auxiliary hook 18b is formed. The inner surface of the mounting base 12 on which the first auxiliary hook 18b is formed may be referred to as a substrate mounting surface.

The circuit board 50 includes a sensor unit 51 for detecting temperature and humidity, a wireless communication unit 53 for transmitting sensed information through wireless communication, and a USB port 59 for connecting to the USB device .

The circuit board 50 includes both a component side on which components such as a chip constituting a circuit are mounted and a solder side on which the components are soldered on the opposite surface to the C side .

The sensor unit 51 may include a temperature and humidity sensor for sensing temperature, humidity, and the like. The temperature / humidity sensor is formed of a chip and can be installed on the C surface (54) of the circuit board.

The wireless communication unit 53 may include an antenna unit 53a for performing wireless communication and a communication chip 53b. The antenna unit 53a may be formed in the circuit board 50 in a pattern. That is, the antenna unit 53a may be printed on the C-plane 54 in a pattern of a circuit board.

The communication chip 53b may be provided on the C-surface, which is the component mounting surface of the circuit board 50. The wireless communication unit 53 may perform wireless communication using a communication method such as zigbee, Bluetooth, WiFi, or the like. The circuit board 50 may form a cut portion 52 for smooth flow of the air flowing in the case 20. For example, the cut portion 52 may cut a predetermined area of the upper portion of the circuit board 50 except for a portion to be coupled with the substrate rib 27, thereby widening the air passage. Therefore, circulation of the air communicated with the upper flow space 3 is facilitated, so that it becomes easier to detect the temperature, the humidity, and the like.

The USB connection port 59 may correspond to the device connection hole 15 of the base 10. That is, the circuit board 50 can be mounted on the base 10 such that the USB connection port 59 is aligned with the position where the device connection hole 15 is formed. For example, the USB connection port 59 may be installed at a lower portion of the circuit board 50 so that the lower end of the circuit board 50 is mounted to the base 10. Thus, the USB device is inserted from the outside through the device connection hole 15, and the inserted USB device can be connected to the USB connection port.

The secondary battery 57 may be placed in the inner space of the case 20 to correspond to the second wall. In addition, the secondary battery 57 may be mounted on the base 10 and placed in the installation space 17.

The secondary battery 57 is connected to a harvester 58 and can be charged with electric power from the harvester 58. Therefore, the secondary battery can supply power to the circuit board 50. The secondary battery 57 may include a lithium ion battery, a NaS battery, a reox flow cell, and the like. However, it is preferable that the secondary battery 57 is a lithium ion battery which is used in portable electronic devices with a small degree of self-discharge.

The secondary battery 57 can be used as an emergency power supply for the circuit board 50. For example, if there is light in the installation space, harvesters can generate electrical energy constantly. However, even when the light is not supplied due to the off state of the light emitting device, it is necessary to detect the light through the temperature and humidity sensor. In this case, the circuit board can receive power through the secondary battery 57. That is, the secondary battery 57 can supply power to the circuit. On the other hand, even if the secondary battery 57 is not provided, power can be supplied to the circuit board 50 due to its own power supply through the harvester 58.

When the secondary battery 57 is discharged, current may flow in the reverse direction through the USB port 59 of the circuit board 50 to charge the secondary battery 57. In addition, when the secondary battery 57 is completely discharged, it is also possible to supply power to the circuit board 50 by using the USB device.

On the other hand, the secondary battery 57 may include a charging circuit 56 for charging. The charging circuit may include a converter for charging a secondary battery (battery) by changing a voltage of a power received from the harvester.

The harvester 58 may include a solar cell or the like. The solar cell collects energy from the illumination of the showcase and charges the secondary battery 57. Given that the showcase maintains a very bright light, energy collection through the solar cell can be done smoothly. The solar cell of the sensor module 1 can continuously collect energy to charge the secondary battery 57 irrespective of whether the sensor module 1 is paired and whether the sensor module 1 is operated or not.

The solar cell can generate electric energy (electric power) using light incident through the window 30

The harvester 58 can be mounted on the harvest receiving portion 19 of the base 10. The space formed by the grooves formed by the harvester accommodating portion 19 for mounting the harvester 58 is called a harvester accommodating space 19a. The lower surface of the harvester is mounted and supported in the harvester accommodating space 19a so that the harvester 58 can be mounted on the base 10.

In addition, the harvester 58 may be placed in the inner space of the case 20 so as to correspond to the third wall. That is, the harvester 58, the secondary battery 57, and the circuit board 50 may be positioned to correspond to the third wall, the second wall, and the first wall, respectively.

The harvester 58, the secondary battery 57 and the circuit board 50 can be mounted on the base 10 so as to correspond to one surface of the triangular prismatic mounting base 12 . The harvester 58 may be installed in a direction parallel to the outer surface of the installation base on which the harvestor accommodating portion 19 is formed and the secondary battery 57 may be installed on the installation base on which the second auxiliary hook 18c is formed The circuit board 50 can be installed in the installation space 17 in parallel with the inner surface of the installation base on which the first auxiliary hook 18b is formed .

5 is a bottom view showing a part of the configuration of a sensor module according to an embodiment of the present invention. The flow characteristics of the air passing through the inside of the sensor module 1 will be described with reference to FIG.

Referring to FIG. 5, the sensor module 1 can circulate air flowing in and out of the sensor module 1. For example, when a desk-top type sensor module 1 is installed in a room, the warm air may be increased in volume and the cold air may be lowered. Unlike the wall-mounted sensor module 1, which is mainly installed in a showcase, the desk-top sensor module 1 installed on a desk in an indoor space does not control the temperature only in the local space around the sensor module 1, air can flow in and out from the lower flow space 4 and the upper flow space 3 through the convection phenomenon because it is mainly used in a space between the room and the room or the hall space having a large area.

Hereinafter, for ease of explanation regarding the air flow inside the sensor module 1, description will be made on the basis that the air flows into the lower flow space 4 and flows into the upper flow space 3.

Since the portion of the air flowing into the lower flow space 4 formed in the space between the base 10 and the lower end of the case 20 is blocked by the hook 18 and the case 20, It is possible to intensively flow into the inner space of the rounded corners forming the vertexes of the corners 20. On the other hand, it is obvious that the air flowing in close contact with the inner surface of the case 20 has a very low flow rate due to a no slip condition. In addition, the inflow air can be disturbed by the harvester 58, the secondary battery 57, and the circuit board 50 which are disposed in close contact with the window. At this time, the air flows into the space between the inner surface of the case 20 and the harvester 58, the secondary battery 57, and the circuit board 50 to reach the upper flow space 3, 58, the secondary battery 57, and the circuit board 50, and reach the upper flow space 3.

Considering the above-described sticking conditions, the air flowing into the spaces formed by facing the harvester, the secondary battery, and the circuit board, which are less influenced by the solid, can flow smoothly and quickly from the air flowing close to the inner surface of the case It can flow into the space and flow into the space. Therefore, the sensor portion 51 provided on the C face 54 of the circuit board 50 is not disposed on the inner surface of the case 20 but in a direction in which the harvester 58 and the secondary battery 57 are viewed Lt; / RTI > That is, the sensor unit 51 should be installed in a direction in which the center axis of the case 20 is viewed, so that it is advantageous to detect temperature, humidity, etc. by smooth air flow. It can be understood that the C face 54 of the circuit board 50 should be installed on the base 10 so as to face the central axis of the case 20. [ Alternatively, it can be understood that the S-plane of the circuit board 50 is disposed so as to face the inner side of the case 20. [ Alternatively, it can be understood that the C face 54 of the circuit board 50 is installed in a direction in which the secondary battery 57 or the harvester 58 is viewed.

Further, the air flowing in the vicinity of the secondary battery 57 and the harvester 58 can be affected by heat. For example, the secondary battery 57 functions as a power source and can generate heat while supplying power to the circuit board. In this case, the sensor unit 51, which detects the temperature and the humidity by using the air in the space where the sensor module 1 is installed to flow into the sensor module 1 and flows, There is a danger. Therefore, the sensor unit 51 provided on the circuit board 50 can be installed at a position as far as possible from the secondary battery 57 and the harvester 58.

That is, the sensor unit 51 installed on the circuit board 50 can be installed at a position higher than the secondary battery 57 in order to accurately detect the temperature, the humidity, and the like. For example, when the imaginary quadrant is divided by forming the X axis and the Y axis with respect to the center point of the C plane 54 of the circuit board 50, the first quadrant and the fourth quadrant are divided into the first and second quadrants, The space of the air is insufficient due to the size of the sensor 50, and at the same time, it is close to the harvester 58, so that it may not be preferable to install the sensor unit 51. In addition, since the third quadrant is located close to the secondary battery 57, air and the sensor may be affected by the heat of the secondary battery 57, which may be undesirable as the installation position of the sensor unit 51. Therefore, it is preferable that the sensor unit 51 is installed in the second quadrant so as to be relatively separated from the secondary battery 57 and the harvester 58 and to detect a relatively accurate temperature and humidity. The sensor unit 51 detects the position of the circuit board 50 which is maximally spaced from the secondary battery 57 and the harvester 58 in the direction toward the center axis of the sensor module 1 or the case 20, .

On the other hand, the wireless communication unit 53 may be adversely affected by wireless communication such as receiving radio wave interference due to the secondary battery 57. Therefore, the antenna unit 53a may be printed on the upper edge of the circuit board to be away from the secondary battery. In addition, it is preferable that the antenna portion 53a is installed in a pattern at a higher position than the secondary battery 57. That is, the antenna unit 53a may be installed at a higher position than the secondary battery so as to be spaced apart from the temperature / humidity sensor. Therefore, it is possible to prevent an unstable communication state from being caused by the influence of radio waves due to the secondary battery 57. [

6 is a diagram illustrating a wireless connection between a sensor module and a gateway according to an exemplary embodiment of the present invention. 6, the communication operation of the present invention will be described.

Referring to FIG. 6, the sensor module 1 includes an energy harvester 58 such as a solar cell, and a charging circuit 56 connected to the energy harvester to convert the energy collected by the secondary battery 57 into a chargeable state do. The charging circuit may include a converter for charging the battery by changing the voltage of the power received from the solar cell. That is, the charging circuit may be a power conversion device for converting the electric energy obtained from the solar cell into a voltage required for charging the battery, the control unit, and the operation of the sensor unit. The secondary battery 57 supplies necessary power to the control unit 55, the sensor unit 51, and the wireless communication unit 53.

The sensor module 1 of the present invention is a portable sensor module configured in a compact size and can be installed at various positions such as being installed on a ceiling of a shelf of a showcase or placed on the floor.

 The solar cell of the sensor module 1 collects energy from the illumination of the showcase to charge the secondary battery 57. Given that the showcase is maintaining a very bright light, energy collection through the solar cell can be done smoothly. The solar cell of the sensor module 1 continuously collects energy regardless of whether the sensor module 1 is paired with the gateway 60 and whether or not the sensor module 1 is operated to charge the secondary battery 57 do. Even when the power switch of the sensor module 1 is turned off, the solar cell and the charging circuit 56 can be continuously operated to charge the secondary battery 57. [

The sensor module 1 may include a switch unit 45 composed of a power switch. The switch unit 45 may connect or disconnect a power source for operating the circuit from the secondary battery 57 through a switching operation. When the power source is connected, the sensor module 1 can perform wireless communication.

The operation of the switch unit 45 may be performed by operating the button 40 of the user. For example, the user can press the button 40 and press it to turn the power switch on or off. When the power switch of the switch unit 45 is on, the controller 55 controls the sensor unit 51 and the wireless communication unit 53 to perform temperature and humidity sensing and communication operations.

The control unit 55 controls the pairing of the gateway 60 and the sensor module 1 and the communication between the wireless communication unit 53 and the gateway 60. The gateway 60 and the sensor module 1 may be paired via a network such as ZigBee or Bluetooth and the controller stores information of the gateway 60 paired with the sensor module 1. The information of the gateway 60 thus paired can be updated. For example, the sensor module 1 is provided with a pairing button for inputting a command for starting or completing the pairing operation, so that the pairing, unpaired, and updated with the gateway 60 are possible.

On the other hand, when the pairing is performed, the operation state can be visually displayed through the LED provided in the sensor module 1. [

The control unit 55 controls whether the temperature / humidity information of the sensor unit 51 is acquired. For example, when the wireless communication unit 53 and the gateway 60 are paired, the control unit 55 causes the sensor unit 51 to acquire temperature and humidity information (conversely, the sensor module and the gateway are not paired The sensor unit will not be activated).

The sensor unit 51 measures temperature and / or humidity, converts the temperature and / or humidity into an electrical signal, and transmits the electrical signal to the control unit 55. The temperature and humidity of the sensor unit may be measured at predetermined time intervals or continuously.

The control unit 55 may transmit the temperature and humidity information received from the sensor unit 51 to the gateway 60 paired with the wireless communication unit 53.

The gateway 60 transmits the identification code or ID of the paired sensor module 1 and the temperature and humidity information received from the corresponding sensor module to the central control unit 65. The central control unit 65 determines how much the temperature of any compartment of the showcase 110 is controlled by using the identification code of the paired sensor module 1 and the temperature and humidity information

7 is a view showing an indoor space in which a sensor module according to an embodiment of the present invention is installed. One embodiment in which the sensor module is used will be described with reference to Fig.

Referring to FIG. 7, the first air conditioner 101 and the second air conditioner 102 are installed in the indoor spaces A, B, and C, respectively. The indoor spaces A, B and C may be partitioned into walls.

The sensor module (1) installed in each indoor space can generate electric energy by using the light irradiated to the installed indoor space, so that the sensor module (1) can operate independently without the power connection line.

The first air conditioner and the second air conditioner each have a gateway 60, and the gateway 60 is a full function device (FFD) that can be connected to a plurality of sensor modules at the same time.

The gateways 60 of the first air conditioner 101 are wirelessly connected to a plurality of sensor modules 1 installed in the indoor spaces A and B, May be paired to the gateway 60 in a state associated with each of the nodes 131 and 134. [

The gateway 60 of the second air conditioner 102 is wirelessly connected in a state of being paired with the wireless communication unit 53 of the sensor module 1 installed in the indoor space C and is also connected to the second air conditioner 102 in association with the discharge ports 131, 134.

The wireless communication unit 53 of the sensor module 1 may be an RFD (redeced function device) as a terminal device. Since the sensor module 1 illustrated in the embodiment of the present invention does not need to be connected to other devices than the air conditioner, it can be configured with a simple RFD with low power consumption.

Since the gateway 60 of the first air conditioner 101 and the gateway 60 of the second air conditioner 102 are FFDs, the plurality of sensor modules 30 located below and the gateways 60 ) Can also be paired with each other.

On the other hand, in the case where a plurality of air conditioners as in the embodiment are installed in the unseparated indoor space, the sensor module 1 may not be paired in correspondence with the second air conditioner 102. However, even if the sensor module 1 is not paired, the temperature and humidity information of the space to be air-conditioned by the corresponding outlet port is the same as that of the sensor connected to the first air conditioner 101 installed adjacent to the second air conditioner 102 From the sensor module 1 installed in the vicinity of the air-conditioning space from the second air conditioner 102 among the modules. That is, since the second air conditioner 102 is connected to the gateway 60 of the first air conditioner 101 through the gateway 60, the second air conditioner 102 can control the operation of the first air conditioner 101, The controller 101 receives the temperature and humidity information received from the sensor module 304 connected to the air conditioner 101 through the communication between the gateways 60 and receives the temperature and humidity information from the sensor module 304 connected to the air conditioner 101 via the outlet port of the second air conditioner 102 And can be utilized as information on the temperature and humidity of the space.

Specifically, the sensor module 1 placed in the indoor space B can be paired with the first air conditioner 101. Therefore, the air conditioning control through the discharge port 134 of the first air conditioner 101 is based on the temperature and humidity information measured by the sensor module 1. The air conditioning control through the outlet of the second air conditioner 102 without the separately paired sensor module can be performed based on the temperature and humidity information measured by the sensor module 1 of the first air conditioner 101 . Particularly, this type of temperature and humidity information collection is advantageously applied when the air conditioning spaces of neighboring air conditioners overlap each other.

The person living in the room moves with the paired sensor module 1 in association with the discharge port of the air conditioner corresponding to the place where the person himself / herself is mainly located. The sensor module 1 ) And the power of the sensor module 1 can be turned on. The control unit 55 of the sensor module 1 provides the temperature and humidity information measured by the sensor unit 51 to the air conditioner installed in the corresponding space through the wireless communication unit 53. The air conditioner So that the amount of air discharged from the discharge port can be controlled.

8 is a configuration diagram of a showcase, an external gateway, and a central control unit provided with the sensor module according to the embodiment of the present invention. An embodiment of a showcase having a sensor module and a network system configuration will be described with reference to FIG.

Referring to FIG. 8, the showcase 110 equipped with the sensor module 1 according to the present invention can constitute a network system. The network system is provided with a sensor module 1 for measuring temperature and humidity at predetermined positions in showcases 110 installed in a store, and wirelessly connecting these sensor modules 1 to the gateway 60 And is completed by connecting the gateway 60 and the central control unit 65 by wire or wirelessly.

A plurality of sensor modules (1) are installed in the area where the temperature and humidity need to be monitored in the showcase (110). For example, these sensor modules 1 may be installed one by one or two by one for each floor of the shelf. Further, the position change, addition, and deletion of the sensor module 1 can be freely performed even after the network is established.

Each sensor module 1 transmits and receives data wirelessly with the gateway 60, and the wireless data can be transmitted optically, propagatively, electrically, or electromagnetically. In one example, each sensor module 1 may individually communicate wirelessly with the gateway 60, and such communication may be by ZigBee or Bluetooth. Various other methods such as infrared, WiFi, etc. may be applied to the communication method. However, if ZigBee and Bluetooth are applied, the data can be bypassed even if there is an obstacle between the gateway 60 and the sensor module 1, the speed of pairing and communication reaction is very fast, and power consumption is small.

The sensor module 1 is provided with a sensor unit 51 for measuring temperature and / or humidity so that the sensor module 1 measures the temperature and humidity of a zone in the showcase 110, And can wirelessly provide it to the gateway 60. [ The gateway 60 is connected to the sensor module 1 ID and the temperature and humidity information provided by the corresponding sensor module to the central control unit 65. [ The central control unit 65 identifies a showcase zone in which the sensor module is installed based on the ID of the sensor module 1 and controls the amount and flow rate of cool air discharged to the showcase zone based on the temperature and humidity information of the zone.

In FIG. 8, it is exemplified that the showcase 110 is divided into three zones 111, 112 and 113, and at least one sensor module 1 is installed in each zone.

According to the present invention, on the basis of the zone where the sensor module 1 is installed and the temperature and humidity information of the zone, by controlling the cool air supplied to the zones 111, 112 and 113, Humidity can be adjusted.
