[0002] The IoT-based stop-and-go detection component (also known as the stop-and-go monitoring system) refers to an intelligent monitoring system that uses IoT technology to monitor the movement of equipment, vehicles, people or other objects to determine whether they are stopped or in motion.

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The present invention will be further described below in conjunction with the embodiments.

[0050] Example 1

[0051] At present, many electrical equipments need to be monitored, especially to know in real time whether the equipment is in a stopped state or in a running state. However, electrical equipments will generate heat when they are working, and the internal temperature will gradually rise. If the heat cannot be dissipated, it will cause damage to the electrical equipments. When the existing stop and go detection components based on the Internet of Things monitor the electrical equipments, they can usually only monitor and judge whether the electrical equipments need to be in a "stopped" or "running" state, but cannot protect the electrical equipments, and their functions are single.

[0052] Based on this, the present invention provides a stop-and-go detection component based on the Internet of Things, referring to Figures 1 to 5 ,include:

[0053] The chassis body 1 has a device slot 2 on the front side.

[0054] The heat dissipation unit is placed in the equipment slot 2; specifically, the heat dissipation unit includes a heat dissipation fan 3 and a heat dissipation hole 4, the heat dissipation hole 4 is opened in the equipment slot 2, the heat dissipation fan 3 includes a rotating shaft 31 and fan blades 32, the rotating shaft 31 is rotatably arranged in the equipment slot 2; the fan blades 32 are provided with a plurality of fan blades 32 and a plurality of fan blades 32 are arranged in a ring array on the rotating shaft 31.

[0055] The rotation of the rotating shaft 31 drives the plurality of fan blades 32 to rotate, and the rotation of the fan blades 32 can quickly dissipate the heat inside the chassis.

[0056] It can be known that the number of cooling fans 3 is set according to the specific situation, that is, the number of cooling fans 3 is not only one, but can also be two or more. Considering the cost and cooling effect, two cooling fans 3 are provided in this embodiment, and each cooling fan 3 includes a rotating shaft 31 and multiple fan blades 32.

[0057] The driving assembly 22 is connected with the heat dissipation unit and is used to drive the heat dissipation unit to work; specifically, the driving assembly 22 includes a driving motor 224, a connecting rod 221, a first sprocket 222, a second sprocket 223 and a chain 225.

[0058] The drive motor 224 is installed on the equipment slot 2;

[0059] The connecting rod 221 is fixedly connected to the rotating shaft 31, so that the connecting rod 221 can rotate synchronously with the rotating shaft.

[0060] The first sprocket 222 is fixedly sleeved on the connecting rod 221;

[0061] The second sprocket 223 is fixedly mounted on the output end of the driving motor 224;

[0062] The chain 225 is annular and meshes with the second sprocket 223 and the first sprocket 222 for transmission.

[0063] The working process is as follows: when the driving motor 224 is started, the second sprocket 223 rotates, and after meshing with the chain 225, it drives the chain 225 to move and the first sprocket 222 to rotate, thereby driving the rotation of the rotating shaft 31, so that the fan blades 32 rotate accordingly to dissipate heat.

[0064] In this embodiment, two heat dissipation fans 3 are provided, and the driving assembly 22 includes two connecting rods 221 which are coaxially fixedly connected to the two rotating shafts 31 respectively, and the rod bodies of the two connecting rods 221 are fixedly sleeved with the first sprocket 222, and the rear side of the chassis body 1 is fixedly installed with a driving motor 224, and the output end of the driving motor 224 is fixedly sleeved with the second sprocket 223, and the outer sides of the multiple first sprockets 222 and the second sprocket 223 are rotated together with a chain 225, and the driving motor 224 drives the second sprocket 223 to rotate, and the two first sprockets 222 cooperate with the chain 225 to drive the two first sprockets 222 and the second sprocket 223 to rotate synchronously, drive the two connecting rods 221 to rotate, drive the two rotating shafts 31 to rotate, and drive the multiple fan blades 32 to rotate.

[0065] The control unit is installed on one side of the chassis body 1 and is electrically connected to the driving component 22 to control the air dissipation efficiency of the heat dissipation unit.

[0066] Example 2

[0067] Based on Example 1, this embodiment provides a stop-and-go detection component based on the Internet of Things, such as Figure 3 As shown, different from Example 1, one end of the connecting rod 221 of this embodiment is connected to a cleaning assembly, and the cleaning assembly rotates synchronously with the rotating shaft 31 to improve the heat dissipation efficiency.

[0068] Electrical equipment is prone to accumulate dust after being used for a period of time, and dust accumulated in the heat dissipation holes 4 will affect the heat dissipation efficiency of the entire chassis body 1. In order to facilitate the cleaning of the outside of the chassis body 1 and reduce the blockage of the heat dissipation holes 4, it is configured as follows: a cleaning component is connected to one end of the connecting rod 221, and the cleaning component rotates synchronously with the shaft 31 to improve the heat dissipation efficiency.

[0069] The cleaning assembly in this embodiment includes a rotating rod 5 and a cleaning rod 6. Specifically, the other ends of the two connecting rods 221 are coaxially fixedly connected to the rotating rod 5, and the rod bodies of the two rotating rods 5 are fixedly connected to the cleaning rod 6. The cleaning rod 6 has a brush that abuts against the back of the device slot 2. The rotation of the two connecting rods 221 drives the two rotating rods 5 to rotate, and drives the two cleaning rods 6 to rotate, and the cleaning rods 6 rotate in close contact with the chassis body 1, so that when the rotating shaft 31 rotates to dissipate heat, the cleaning rods 6 clean the dust on the device slot 2 to ensure the heat dissipation efficiency.

[0070] Example 3

[0071] Based on Example 1, this embodiment provides a stop-and-go detection component based on the Internet of Things, such as Figure 2 and Figure 4As shown, different from Example 1, a first mounting groove 7 and a second mounting groove 8 arranged linearly are opened on one side of the chassis body 1 of this embodiment, and the control unit includes a push plate 9, an expansion liquid 12, a sliding rod 17, a pressure sensor, a reset spring 10 and a sliding resistor.

[0072] The push plate 9 is slidably installed in the second installation groove 8;

[0073] The expansion liquid 12 is filled between the push plate 9 and the side wall of the second mounting groove 8; further, the expansion liquid 12 is mercury or mineral oil. Specifically, the working principle of the expansion liquid 12 is based on thermal expansion (also called thermal expansion coefficient). When the liquid is heated, the molecular motion intensifies, and the gap between molecules increases, thereby causing the liquid volume to increase. On the contrary, when the liquid is cooled, the molecular motion slows down, the distance between molecules decreases, and the liquid volume decreases. Mercury is one of the earliest expansion liquids 12 used. It has a high thermal expansion coefficient, good thermal conductivity and high stability. The volume change of mercury is obvious with temperature changes, and it can accurately reflect temperature changes. In addition, mineral oil is also a commonly used expansion liquid 12. Mineral oil also has a high thermal expansion coefficient and is safer than mercury.

[0074] The pressure sensor is arranged on the side wall of the second installation groove 8 away from the expansion liquid 12; further, a groove 20 is opened on the back of the chassis body 1, and a buzzer 21 is installed in the groove 20. The pressure sensor 11 signal is connected to the controller, and the controller is electrically connected to the buzzer 21. When the pressure applied to the pressure sensor 11 reaches its set threshold, it indicates that the temperature in the chassis is too high, and the temperature in the chassis cannot be guaranteed to drop to a safe value range after heat dissipation. The controller controls the buzzer 21 to alarm, alerting the staff to stop the equipment operation, conduct equipment inspection and maintenance, and ensure the safety of the equipment operating environment.

[0075] The return spring 10 is arranged on the side of the push plate 9 away from the expansion liquid 12 and against the side wall of the second mounting groove 8; the function of the return spring 10 is: when the expansion liquid 12 shrinks, the push plate 9 moves together under the action of the return spring 10, so that the pressure of the pressure sensor decreases, the temperature drops to a safe range, and the current of the sliding resistor decreases, thereby controlling the cooling fan 3 to reduce the working efficiency.

[0076] The sliding resistor is arranged in the first mounting groove 7 and is electrically connected to the driving motor 224;

[0077] The sliding rod 17 is arranged on one side of the push plate 9 and passes through the second mounting groove 8 to be connected with the sliding resistor.

[0078] Furthermore, the sliding rheostat includes a resistance column 13, a vertical plate, a moving ring 15 and a fixed ring 14.

[0079] The resistor column 13 is fixedly installed in the second installation groove 8;

[0080] There are two vertical plates, which are respectively placed at both ends of the resistor column 13;

[0081] The fixing ring 14 is fixedly mounted on the side of the resistor column 13 away from the sliding rod 17;

[0082] The moving ring 15 is slidably mounted on the resistor column 13 and is fixedly connected to one end of the sliding rod 17;

[0083] The outer sides of the fixed ring 14 and the movable ring 15 are fixedly connected with connecting wires 16 , and the two connecting wires 16 and the resistor column 13 are electrically connected to the driving motor 224 .

[0084] The specific operation process of the sliding rheostat is as follows: when the distance between the fixed ring 14 and the movable ring 15 is the largest, the length of the resistor column 13 in the closed loop is the largest, and the current in the closed loop is the smallest. When the movable ring 15 is located at the rightmost side of the resistor column 13, the resistance of the resistor column 13 connected to the closed loop is the largest. At this time, there is almost no current in the closed loop, and the cooling fan 3 is in a non-working state. When the movable ring 15 is located at the rightmost side of the resistor column 13, it indicates that the push plate 9 in the second mounting groove 8 is located at the rightmost side. At this time, the volume of the expansion liquid 12 is the smallest, and the temperature inside the chassis is low. Usually, this situation indicates that the equipment in the chassis is not running and the equipment has been running for a short time.

[0085] Example 4

[0086] To further improve the safety of the equipment, Figure 3 As shown, in this embodiment, a groove 20 is provided on the back of the chassis body 1, and a buzzer 21 is installed in the groove 20; a pressure sensor connected to one end of the reset spring 10 is provided on the side wall of the second installation groove 8, and the pressure sensor signal is connected to the controller, and the controller is electrically connected to the buzzer 21. When the pressure on the pressure sensor 11 reaches its set threshold, it means that the temperature in the chassis is too high, and the temperature in the chassis cannot be guaranteed to drop to a safe value range after heat dissipation. The controller controls the buzzer 21 to alarm, alerting the staff to stop the equipment operation, conduct equipment inspection and maintenance, and ensure the safety of the equipment operation environment.

[0087] Example 5

[0088] Further, if Figure 1 As shown, a protective plate 18 is fixedly connected to the outer side of the first mounting groove 7. In this embodiment, the protective plate 18 is made of an acrylic transparent plate, so that the use of the sliding rheostat can be observed and the acrylic transparent plate has high strength and can play a better protective role.

[0089] Example 6

[0090] Further, if Figure 1 As shown, a heat conducting plate 19 is fixedly connected to the outer side of the second mounting groove 8. The material of the heat conducting plate 19 is graphene material. Graphene is a very excellent heat conducting material with extremely high thermal conductivity (many times higher than copper). Graphene film or graphene-enhanced composite material can achieve effective heat conduction, and can transfer heat by radiation, convection, etc. without direct contact. As the equipment runs for a long time, the temperature inside the chassis rises, the expansion fluid 12 is heated, the molecular motion intensifies, and the gaps between molecules increase, thereby causing the liquid volume to increase. The increase in the volume of the expansion fluid 12 pushes the push plate 9 toward the first The movable ring 15 is pushed in the direction of the mounting groove 7, and the sliding rod 17 pushes the movable ring 15 to move on the outside of the resistor column 13 toward the fixed ring 14, so that the resistance in the closed circuit is reduced. According to Ohm's law I=U / R, when the voltage is constant, the smaller the resistance, the larger the current in the circuit. As the temperature inside the chassis continues to rise, the sliding rod 17 pushes the movable ring 15 to reduce the resistance in the circuit and increase the current in the circuit. According to P=UI, the larger the current, the greater the power. Therefore, as the temperature inside the chassis increases, the power of the cooling fan 3 increases, and the cooling power of the cooling fan 3 can be automatically adjusted according to the temperature inside the chassis.

[0091] The specific use principle of the present invention is as follows:

[0092] When the moving ring 15 is located at the rightmost side of the resistor column 13, the resistance of the resistor column 13 connected to the closed loop is the largest. At this time, there is almost no current in the closed loop, and the cooling fan 3 is in a non-working state. When the moving ring 15 is located at the rightmost side of the resistor column 13, it indicates that the push plate 9 in the second installation groove 8 is located at the rightmost side. At this time, the volume of the expansion liquid 12 is the smallest, and the temperature inside the chassis is low. At this time, the reset spring 10 is in the original length state, and the pressure sensor 11 does not detect pressure. Usually, this situation indicates that the equipment in the chassis is not running;

[0093] When the device is running, the temperature inside the chassis starts to rise, the expansion liquid 12 is heated, the molecular motion is intensified, and the gaps between molecules are enlarged, thereby causing the volume of the liquid to increase. The increase in the volume of the expansion liquid 12 pushes the push plate 9 toward the direction of the first mounting groove 7, and the return spring 10 is compressed. When the pressure sensor 11 receives pressure, it indicates that the device starts to run;

[0094] As the equipment runs for a long time, the temperature inside the chassis rises, and the expansion fluid 12 is heated, resulting in an increase in volume. The increase in the volume of the expansion fluid 12 pushes the push plate 9 toward the first mounting groove 7, and the sliding rod 17 pushes the movable ring 15 to move on the outside of the resistance column 13 toward the fixed ring 14, and the resistance in the closed circuit decreases. According to Ohm's law I=U / R, when the voltage is constant, the smaller the resistance, the greater the current in the circuit. As the temperature inside the chassis continues to rise, the sliding rod 17 pushes the movable ring 15 to reduce the resistance in the circuit and increase the current in the circuit. According to P=UI, the larger the current, the greater the power. Therefore, as the temperature inside the chassis increases, the power of the cooling fan 3 increases, and the cooling power of the cooling fan 3 can be automatically adjusted according to the temperature inside the chassis.

[0095] When the pressure on the pressure sensor 11 reaches its set threshold, it means that the temperature inside the chassis is too high. After heat dissipation, the temperature inside the chassis cannot be guaranteed to drop to a safe value range. The controller controls the buzzer 21 to alarm, alerting the staff to stop the equipment operation, perform equipment inspection and maintenance, and ensure the safety of the equipment operating environment.

[0096] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
