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.

There are various environments such as an indoor space, an air conditioning environment, and a refrigerator as similar environments.

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. Alternatively, when the sensor module 1 is a wall-mounted type installed on a wall of a showcase, the case 20 may have a triangular prism shape having a triangular bottom surface in order to optimize the incidence area of light. Further, by deforming each corner point formed by the triangular column into a rounded shape, the user can easily grasp the sensor module 1, and the aesthetics of the sensor module can be further improved. The case 20 according to the embodiment of the present invention will be described on the basis of a triangular prism.

In addition, the case 20 can be formed into a columnar shape with an empty interior. Here, one outer surface of the case 20 fixed to the wall is called a mounting surface, and the other outer surface of the case 20 facing the light emitting source such as the sun or fluorescent lamp is called an incident surface. That is, the case 20 may include the attachment surface, the light emitting surface, and a connection surface connecting the attachment surface and the light emitting surface.

When the case 20 has a triangular prism shape, a magnet may be provided on one outer surface of the case 20, or a suction plate may be provided on the showcase wall surface. That is, a magnet, an attracting plate, or the like may be provided on the attachment surface. At this time, the installation direction of the sensor module 1 may be such that the longitudinal direction of the case 20 is horizontal to the wall. For example, when the mounting surface is provided with a double-sided tape or the like on a wall surface of a showcase, light can be received from a light emitting device provided on a ceiling of a showcase at an incident angle of 45 degrees or the like. Therefore, since the area of the window 30 to reach the harvest can be optimized, the energy production efficiency of the harvester 58 installed in the sensor module 1 in close contact with the window 30 can be improved, Can be further improved.

Since the light emitting surface is the outer surface of the case facing the light emitting device and the light emitting device, it can be understood that the window 30 is provided. Here, it is obvious that the attachment surface on which the double-sided tape or the like is provided should not be the outer surface of the case 20 on which the window 30 is mounted. That is, the attachment surface and the light emitting surface can be distinguished from each other.

The attachment surface and the light emitting surface may be formed at an acute angle. Specifically, when the case 20 of the triangular prism shape is installed such that one outer surface is attached to the wall and the other outer surface is made incident on the light, for the easy and optimized incidence of the structural stability and light, And the light emitting surface on which the light is incident preferably forms an acute angle.

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 from the upper end of the case 20 toward the inside of the case. And may extend in the direction of the center of the case along the upper end of the case 20 in detail. 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. That is, the upper surface of the case 20 may be maintained in an open state. Therefore, 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.

The receiving groove 26 may include a first receiving groove 26a, a second receiving groove 26b, and a third receiving groove 26c.

The first receiving groove 26a may protrude downward from the center of the seating surface corresponding to the direction in which the front case 21 is located. The second receiving groove 26b may protrude downward from the center of the seating surface in the direction in which the second auxiliary case 24 is located. The third receiving groove 26c may protrude downward from the center of the seating surface in the direction in which the first auxiliary case 23 is located. That is, the plurality of receiving grooves 26a, 26b, and 26c may be spaced apart from each other such that a virtual extension line connecting the centers of the plurality of receiving grooves 26a, 26b, and 26c forms a regular triangle.

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, the substrate ribs 27 may be protruded downward from the upper end of the case 20. Further, the substrate ribs 27 may be provided on the bottom surface of the seating surface.

 The substrate ribs 27 may be formed to correspond to the first walls. The shape and size of the substrate ribs 27 can be variously formed. For example, the substrate rib 27 may be formed by recessing the upper end of the case 20 inward. Further, the lower surface of the skirt 25 may be recessed.

When the substrate ribs 27 are recessed into the upper end of the case 20 and the circuit board 50 mounted on the substrate ribs 27 is formed to have a minimum size, 1) can be minimized. That is, the size of the sensor module 1 can be minimized since the circuit board 50 can be compactly installed as long as the substrate ribs 27 are recessed. The size of the sensor module 1 can be determined by the circuit board 50 which can be relatively larger than the harvester limited by the size of the secondary battery and the window 30. [ As a method for minimizing the size of the sensor module 1, the circuit board 50 itself may be minimized, or if the manufacturing of the circuit board 50 reaches the limit for miniaturization, 20) in the most compact manner. Therefore, the sensor module 1 can be further reduced in size by holding the circuit board 50 by recessing the substrate rib 27 inwardly of the case 20.

The substrate rib 27 may protrude downward from the bottom surface of the skirt 25 so as to correspond to the first wall 25. The substrate rib 27 may have a groove formed therein. The substrate rib 27 may protrude downward from the inside of the upper end of the case 20 so as to correspond to the first auxiliary case 23.

The groove of the substrate rib 27 may fix the upper end of the circuit board 50. Therefore, the upper end of the circuit board is mounted to the groove of the substrate rib 27, and the lower end of the circuit board 50 is mounted to the base 10, thereby fixing the upper and lower portions of the circuit board. Therefore, the circuit board can be stably fixed to the inside of the case 20.

In addition, the substrate ribs 27 may protrude downward from the upper end of the case 20. The substrate ribs 27 may be formed in various shapes. For example, the substrate rib 27 may be formed in the shape of a circle. At this time, the recess formed in the substrate rib 27 may serve to insert and fix the circuit board 50. The substrate rib 27 may include a guide wall capable of fixing both ends of the circuit board so that the circuit board 50 mounted on the base 10 can be slidably inserted.

The grooves formed in the substrate ribs 27 may be formed so as to be parallel to one surface of the case 20 closest to the circuit board 50. For example, the groove of the substrate rib 27 may be formed such that the first auxiliary case 23 and the circuit board 50 are installed in parallel.

The substrate ribs 27 may be formed parallel to a vertical direction at a position where the circuit board 50 is mounted on the base 10. That is, the substrate ribs 27 may be formed to correspond to the vertical direction from the mounting position of the base 10 on which the lower end of the circuit board 50 is mounted. For example, the substrate ribs 27 may be formed on the lower surface of the skirt 25 extending from the first auxiliary case 23. In this case, the substrate rib 27 is formed closest to the first auxiliary case 23, so that the auxiliary hook, which is engaged with the first auxiliary case, is connected to the circuit board 50 mounted on the base 10, As shown in FIG. At this time, the auxiliary hook formed closest to the mounting position of the circuit board 50 mounted on the base 10 may be the first auxiliary hook 18b.

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 plurality of substrate ribs 27 may be formed. For example, the substrate rib 27 may include a first substrate rib 27a and a second substrate rib 27b. In this case, the second substrate ribs 27b can be arranged so as to move in parallel from the first substrate rib 27a and to face each other. The first substrate rib 27a and the second substrate rib 27b may be formed so that both ends of the upper end of the circuit board 50 are inserted and fixed, respectively.

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. 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 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 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. [

In addition, the upper surface of the support base 11 can provide a mounting space for components such as circuit boards, harvesters, and secondary batteries.

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 include a device connector 15 for guiding the external device and the sensor module 1 to be stably connected. For example, the device connector 15 may be formed to insert a USB. 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 connector 15.

In addition, the rising surface 14 may form a reset hole 16 for guiding the user to press the reset button of the circuit board. For example, the user may insert a tool into the reset aperture 16 to depress 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 port 15 and the reset port 16. [

Since the rising 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 connection port 15 and the reset port 16 from breakage or risk of contamination There are advantages to be able to.

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 harvest receiving portion 19 will be described in detail later.

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. [

Further, the hook 18 may be formed to be thinner than the thickness of the mounting base 12. Therefore, the hook can be easily tilted during the hooking operation of the hook 18 and the binding force from the installation base 12 can be lowered.

FIG. 4 is an exploded view showing a part of a structure of a sensor module mounted on a base according to an embodiment of the present invention, and FIG. 5 is a plan view showing a base of a sensor module according to an embodiment of the present invention.

4 and 5, the sensor module 1 may further include a circuit board 50, a secondary battery 57, and a harvester 58 mounted on the base 10, respectively.

The circuit board 50 is installed in the installation space 17. When the power is connected, 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 mounting base 12 may further include a fixed rib 110. The fixing ribs 110 may protrude from both side edges of an inner surface of the mounting base 12. [ Specifically, the fixing ribs 110 protrude from both edges of the mounting base 12 and the rounded inner surface of the mounting base 12 in order to guide insertion of the circuit board 50 along the board mounting surface . For example, it can be formed by protruding in a lattice form.

The fixing ribs 110 are protruded inwardly in parallel to the substrate mounting surface at rounded corners where two inner surfaces of the mounting base 12 abut each other so as to fix both sides of the circuit board 50 can do. The rounded corner at which the two inner surfaces of the mounting base 12 abut each other has an edge formed by the substrate mounting surface and the inner surface of the mounting base 12 on which the main hook 18a is formed, Quot; means an edge formed by the inner surface of the installation base 12 on which the first base 18c is formed. For example, both side surfaces of the circuit board 50 may be inserted into the C-shaped groove formed by the substrate mounting surface and the fixing ribs 110 and mounted on the base 10. Therefore, stable fixing of the circuit board 50 can be achieved.

The fixed rib 110 may include a first fixed rib 111 and a second fixed rib 112.

The first fixing ribs 111 are formed from the edges of the inner surface of the mounting base 12 on which the second auxiliary hooks 18c are formed and the inner surface of the mounting base 12 on which the first auxiliary hooks 18b are formed And can be formed by protruding. For example, the first fixing rib 111 may have a rectangular parallelepiped shape. Therefore, the inner surface of the mounting base 12, on which the first fixing rib 111 and the first auxiliary hook 18b are formed, can form a C-shaped groove, which is called a first installation groove 116 do.

The second fixing rib 112 protrudes from an edge between the inner surface of the mounting base 12 on which the main hook 18a is formed and the inner surface of the mounting base 12 on which the first auxiliary hook 18b is formed . For example, the second fixing rib 112 may have a rectangular parallelepiped shape. Therefore, the inner surface of the mounting base 12 on which the second fixing rib 112 and the main hook 18a are formed can form a C-shaped groove, which is called a second installation groove 117.

The first installation groove 116 and the second installation groove 117 are called installation grooves 115. The circuit board 50 may be inserted into the mounting groove 115 and stably fixed to the base 10 to be mounted thereon.

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 sense or measure the state of the gas flowing inside the case 20. [

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 port 15 of the base 10. That is, the circuit board 50 may be mounted on the base 10 such that the USB connection port 59 is aligned with the position where the device connector 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. Therefore, the USB device is inserted from the outside through the device connector 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 may be connected to the harvester 58 and may be charged with the collected energy. Accordingly, the secondary battery 57 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.

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.

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 the battery by changing the voltage of the power received from the harvester.

The secondary battery 57 may be fixed to the fixing wall 100.

That is, the base 10 may further include a fixing wall 100 protruding upward from the upper surface of the support base 11. [ The fixing wall 100 may be formed in the installation space 17. [

The fixing wall 100 may have various shapes. For example, it may be formed on the upper surface of the support base 11 so as to surround the secondary battery 57. Unlike the harvester and the circuit board, the secondary battery 57 is not fixedly supported in both directions by the base 10 and the skirt 25 due to its size limitation. Therefore, when the sensor module 1 is rotated and installed, it is necessary to securely and firmly fix the sensor module 1 on the base 10. Therefore, the secondary battery 57 can be stably fixed to the base 10 through the formation of the fixing wall 100 in the shape of a letter.

The fixing wall 100 may be formed to be vertically and / or horizontally spaced apart from the inner surface of the mounting base 12 on which the second auxiliary hook 18c is formed. Therefore, the secondary battery 57 can be fixed by the fixing wall 100 and the inner surface of the mounting base 12 where the second auxiliary hook 18c is formed.

The fixing wall 100 may include a first fixing wall 101 and a second fixing wall 102. The first fixing wall 101 may be formed to support and support the longitudinal direction of the secondary battery 57. The second fixing wall 102 may be formed to support the width direction of the secondary battery 57 in a fixed manner. The first fixing wall 101 and the second fixing wall 102 may be connected to each other or may be separately formed to fix the secondary battery 57.

In addition, the secondary battery 57 may be fixed to the fixing wall 100 while being mounted inside a secondary battery fixing member formed to surround the secondary battery. In this case, the secondary battery fixing member may be coupled to the fixing wall 100 to mount the secondary battery on the base 10. For example, the secondary battery fixing member may be formed as a fixing bracket and coupled with the fixing wall 100.

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 is maintaining 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 harvesters 58 may be formed in various shapes, sizes, and the like. However, it is most preferable in terms of cost and efficiency to be formed to correspond to the size of the window 30 due to the nature of being mounted inside the window 30.

The harvesters 58 may be mounted on the harvesting receptacle 19 of the base 10. The harvesting unit 19 is provided with a main hook 18a spaced apart from the outer surface of the installation base 12 by a predetermined distance so that a groove for mounting the harvest 58 is formed on the upper surface of the main hook 18a, It can be formed by extending one point of the upper surface of the upper surface 18a upward. That is, any one point of the upper surface of the main hook 18a can be formed by protruding. Here, the set distance can be set in consideration of the width of the harvester accommodated. For example, the harvestor accommodating portion 19 may be formed in an L-shape on the upper surface of the main hook 18a.

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 secondary battery 57 or the circuit board 50 may be disposed in the inner space of the case 20 so as to correspond to the incident surface, Can be placed in the inner space of the case (20).

The harvester 58, the secondary battery 57 and the circuit board 50 are mounted on the base 10 in parallel so as to correspond to one surface of the triangular columnar mounting base 12 . For example, the harvester 58 can 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 can be installed in the installation base And 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 have.

FIG. 6 is a perspective view showing a case of a sensor module according to an embodiment of the present invention, and FIG. 7 is a bottom view showing a case of a sensor module according to an embodiment of the present invention.

6 and 7, the inner structure of the case 20, the harvester, and the mounting position of the circuit board will be described.

The case 20 may further include a main hook groove 121, a first auxiliary hook groove 122 and a second auxiliary hook groove 123 to engage with the hook 18,

The main hook groove 121 may be recessed at the lower end of the front case 21. Therefore, the main hook 18a can be coupled to the main hook groove 121 through the hooking operation of the hook,

The first auxiliary hook groove 122 may be recessed at the lower end of the first auxiliary case 23. Therefore, the first auxiliary hook 18b can be coupled to the first auxiliary hook groove 122 through the hooking operation of the hook.

The second auxiliary hook groove 123 may be recessed at the lower end of the second auxiliary case 24. Therefore, the second auxiliary hook 18c can be coupled to the second auxiliary hook groove 123 through the hooking operation of the hook.

The main hook groove 121, the first auxiliary hook groove 122, and the second auxiliary hook groove 123 are called hook grooves.

The case 20 may further include a harvester guide 125 capable of sliding and inserting the harvester 58 therein.

A guide wall may be formed on the inside of the front case 21 so that the harvester guide 125 can be slidably inserted in correspondence with the window 30. [ In detail, the inner surface of the front case 21 may protrude in a lattice form at an edge of the first auxiliary case 23 and the second auxiliary case 24. That is, the harvester guide 125 may protrude from the lower end of the case 20 at a position spaced apart from the inner surface of the front case 21 and may extend along the longitudinal direction of the case 20 have. For example, the harvester guide 125 may be formed in a rectangular parallelepiped shape and spaced apart from the inner surface of the front case 21 so as to be elongated along the longitudinal direction of the front case 21. The inner surface of the front case 21 may form a U-shaped groove corresponding to the harvesting guide 125. Therefore, the harvester 58 can be installed in close contact with the window 30 while being slidably inserted along the corresponding grooves of the harvesting guide 125 and the front case 21.

The harvester guide 125 may include a first harvester guide 126 and a second harvester guide 127.

The first harvester guide 126 may protrude from an edge of the front case 21 and the first auxiliary case 23.

The second harvester guide 127 may protrude from an edge of the front case 21 and the second auxiliary case 24.

The grooves formed by the first harvester guide 126 and the second harvester guide 127 may be spaced apart from each other in a parallel position. Accordingly, the first harvester guide 126 and the second harvester guide 127 can stably fix the harvester 58 by guiding both ends of the harvester 58 to be inserted into the sliding manner. That is, the harvester 58 mounted on the harvester receiving portion 19 of the base 10 is slid to the inside of the front case 21 by the first harvester guide 126 and the second harvester guide 127 Can be inserted.

In the case of a solar cell, for example, the harvester 58 has a high brittleness, which may easily be destroyed by external pressure. Therefore, the harvester 58 needs to be stably fixed to the inside of the front case 21. Therefore, the harvester guide 125 can slide and insert the harvester, so that the harvester 58 mounted on the base 10 can be stably coupled to the case 20 without risk of breakage.

8 is a flowchart illustrating a method of assembling a sensor module according to an embodiment of the present invention. A method of assembling the sensor module 1 will be described with reference to FIG.

Referring to FIG. 8, the user starts assembling the sensor module 1 with the base 10 and the case 20 separated. (S1)

First, the user can perform a base assembly step of mounting the circuit board 50, the harvester 58, and the secondary battery 57 on the base 10. (S2)

In the base assembly step, the user may insert the circuit board 50 into the mounting recess 115 formed in the mounting space 17 of the base 10. In this case, the USB port 59 and the device connection port 15 can be positioned and installed in correspondence with each other. Also, the reset hole 16 may be positioned and mounted so as to correspond to the reset button of the circuit board.

The secondary battery 57 may be fixed to the fixing wall 100. The harvester 58 can be installed by mounting a center portion in the harvestor accommodating space 19a formed by the harvestor accommodating portion 19. Thus, the circuit board 50, the harvester 58, and the secondary battery 57 can be fixedly mounted on the base 10.

Then, the user can perform the case assembly step of coupling the window 30 and the button 40 to the case 20. (S3)

In the case assembly step, the user can install the window 30 in the window mounting space 22 formed in the front case 21. The case 20 and the button 40 can be coupled while coupling the connection ring 43 formed in the button 40 to the receiving groove 26 formed in the skirt 25.

The order of the base assembly step and the case assembly step is not limited. Although the base assembly step has been described above for ease of explanation, the case assembly step may be performed first. That is, the base assembling step and the case assembling step can be understood as a gravity assembling step.

Thereafter, the user may perform a base-case coupling step of coupling the base 10 and the case 20 together. (S4)

The user may insert the harvester 58 installed in the base 10 into the harvester guide 125 and slide the same. At this time, the upper end of the circuit board 50 can be fixedly mounted by the substrate ribs 27.

When the circuit board 50 reaches the substrate rib 27, the harvester 58 will reach the uppermost end of the harvester guide 126 as well. At this time, the main hook 18a, the first auxiliary hook 18b, and the second auxiliary hook 18c formed in the base 10 are inserted into the main hook groove 121 formed in the case 20, The hook 122 may be engaged with the second auxiliary hook groove 123 while the hook is engaged.

The assembly of the sensor module 1 can be terminated while the base 10 and the case 20 are engaged by the hooking operation of the hook. (S5)

9 is a view showing a showcase in which a sensor module according to an embodiment of the present invention is installed. An embodiment of a showcase in which the sensor module 1 is installed will be described with reference to FIG.

Referring to Fig. 9, the showcase may be composed of internal divided spaces 201, 202, and 203. Fig. In addition, a light emitting device may be installed in each of the divided spaces 201, 202, and 203 of the showcase and the upper portion of the body of the showcase. The light emitting device may be a fluorescent lamp or the like. That is, the light emitting device can be understood as a light emitting source for emitting light to the sensor module 1.

The sensor module (1) can be installed inside the divided space of the showcase and at the end of the plate forming the divided space, respectively. In this case, the sensor module 1 can be installed as the wall-mounted type sensor module 1. Therefore, the light emitted from the light emitting device can be incident on the sensor module 1. [

The mounting position of the sensor module 1 may be installed so that light generated from the light emitting device 200 can be efficiently irradiated.

The wall-mounted type sensor module 1 may have a triangular prism shape. In this case, a surface of the case of the sensor module may be provided with a magnet or an adsorbent to be mounted on the wall. In addition, one surface of the case provided with the magnet or adsorbent, that is, the mounting surface may be mounted on the wall, and the incident surface of the front case on which the window 30 is formed may be installed so that light is incident thereon. Accordingly, the sensor module 1 having a triangular prism shape can effectively collect light because one side of the case installed on the wall surface and the other side of the case formed with the window have a constant angle. For example, the attachment surface and the incident surface may be formed at an acute angle to efficiently receive light.

When the light emitted from the light emitting device is irradiated on the window 30 having a predetermined angle, the area of the harvester 58 contacting the light can be relatively increased. Therefore, there is an effect that energy production efficiency for generating electrical energy of the harvester is improved. Therefore, the sensor module 1 installed in the illustrated showcase can be configured in a triangular pillar shape to optimize energy production.

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 the area in the showcase 110, It can be converted into an electrical signal and wirelessly provided to an external server device or the like.

The external server receiving the temperature and humidity information provided by the sensor module 1 confirms the showcase zone in which the sensor module is installed through the ID of the sensor module 1 and displays the showcase zone based on the temperature and humidity information of the zone, And controls the amount and flow rate of cold air discharged into the area.

Therefore, 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 each zone 111, 112, 113, Temperature and humidity can be adjusted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the invention is not limited to the disclosed exemplary embodiments. It is obvious that a transformation can be made. Although the embodiments of the present invention have been described in detail above, the effects of the present invention are not explicitly described and described, but it is needless to say that the effects that can be predicted by the configurations should also be recognized.
