Abstract
Description
Technical Field
[0001] This invention belongs to the field of intelligent alarm terminal technology, specifically a multi-sensor alarm device based on NB-IoT and controlled by Bluetooth. Background Technology
[0002] An alarm is an electronic product that uses sound, light, air pressure, or other means to alert or warn us to take certain actions in order to prevent or mitigate the consequences of an event. Alarms are divided into mechanical alarms and electronic alarms. With the advancement of technology, mechanical alarms are increasingly being replaced by advanced electronic alarms. They are frequently used in areas such as system failure, security, transportation, medical rescue, emergency disaster relief, and sensor detection, and are inseparable from social production. Examples include door magnetic sensors and gas detectors.
[0003] In environmental monitoring of manhole covers, utility poles, and outdoor equipment rooms, multi-channel sensor alarms are typically used for data detection. The detection functions include tilt, displacement, water immersion, light sensing, temperature and humidity, and BeiDou + GPS dual positioning. This enables 24-hour real-time monitoring, real-time anomaly reporting, equipment location guidance, data recording and statistical analysis, and effective management of public assets. The multi-channel sensor alarms use NB-IoT / 3G / 4G / 5G links for transmission and can be remotely controlled via Bluetooth. They are deployed in a cloud-based microservice architecture, providing various data control and display methods as well as modular functional components.
[0004] Based on the above, in the practical application of multi-channel sensor alarms, when monitoring the temperature and humidity of the surface or interior of an object, the detection end of the multi-channel sensor alarm is usually embedded inside the object or installed on its surface for contact. The detection end is usually an integrated design. When the multi-channel sensor alarm is installed on an uneven detection surface, it is very easy for the detection end to fail to make full contact with the detection surface, resulting in a gap between the detection end and the detection surface. This reduces the contact area between the detection end and the detection surface, making installation inconvenient and prone to generating large data errors, thus affecting the monitoring accuracy of the multi-channel sensor alarm.
[0005] Therefore, a Bluetooth-controlled multi-sensor alarm based on NB-IoT is proposed to solve the above problems. Summary of the Invention
[0006] To overcome the above-mentioned defects, the present invention provides a Bluetooth-controlled multi-channel sensor alarm based on NB-IoT, which solves the problem that when the multi-channel sensor alarm is installed on uneven detection areas, the detection end is easily unable to make full contact with the detection surface, resulting in a gap between the detection end and the detection surface, thereby reducing the contact area between the detection end and the detection surface. This not only makes installation inconvenient but also easily generates large data errors, affecting the monitoring accuracy of the multi-channel sensor alarm.
[0007] The purpose of this invention is:
[0008] Multiple probes contact the surface to be measured. Since the probes can extend and retract freely within the storage box, they can be arranged according to the shape of the surface. The spring force supports the fixing ring and the probes, ensuring that the probes fit tightly against the surface and maintain their current extended or retracted position. The multi-channel sensor alarm body is then installed on the object to be measured to prevent the probes from moving freely and affecting normal detection. This ensures that the detection end of the multi-channel sensor alarm body can fully contact the detection surface, facilitating installation, reducing data errors, and improving the monitoring accuracy of the multi-channel sensor alarm body.
[0009] The position of the probe is adjusted by the adjustment component, and with the support of the spring, the probe extends out of the air cushion. At this time, multiple probes are in the same extension and retraction position, which enables the main body of the multi-channel sensor alarm to perform the next installation and monitoring work, thus bringing great convenience to the monitoring work.
[0010] The detection motherboard can transmit signals to the detection probes through a conductive sleeve, thus eliminating the need for multi-strand wires and preventing the extension and retraction of the detection probes from pulling on the wires and affecting normal data transmission. Furthermore, the middle part of the detection motherboard is connected to the access terminal of the multi-sensor alarm body through a signal post, enabling the detection motherboard to integrate the data detected by all the detection probes and transmit this data to the multi-sensor alarm body, greatly simplifying the assembly steps of the alarm.
[0011] To achieve the above objectives, the present invention provides the following technical solution: a multi-channel sensor alarm based on NB-IoT and controlled by Bluetooth, comprising a multi-channel sensor alarm body, a support base at the bottom of the multi-channel sensor alarm body, the support base being fixed to a storage box, a conductive component inside the storage box, the middle part of the conductive component penetrating the storage box and the support base and connected to an access terminal at the bottom of the multi-channel sensor alarm body, a plurality of detection components on the conductive component, the plurality of detection components penetrating the storage box, the top end of the detection component being sleeved in a fixing sleeve, the fixing sleeve being disposed at the top of the storage box, a limiting component being snapped into the fixing sleeve, the top end of the detection component being located within the limiting component, a cavity inside the support base, the cavity communicating with the top ends of the plurality of limiting components, and adjustment components on both sides of the support base, the adjustment components communicating with the cavity.
[0012] As a further aspect of the present invention: the main body of the multi-channel sensor alarm includes a Bluetooth module, the main body of the multi-channel sensor alarm uses NB-IoT / 3G / 4G / 5G link transmission, and can be remotely controlled via Bluetooth.
[0013] As a further embodiment of the present invention: the conduction component includes a detection motherboard, which is snapped into a storage box. The detection motherboard has several snap-fit holes, and the detection component is snapped into the snap-fit holes. A signal wire post is provided in the middle of the detection motherboard. An insulating sleeve is fitted over the signal wire post. The insulating sleeve is snapped into the middle of the support base. The signal wire post passes through the support base and is connected to the access terminal at the bottom of the multi-channel sensor alarm body.
[0014] As a further aspect of the present invention: the detection component includes a detection needle, the detection needle is covered with a conductive sleeve, the conductive sleeve is snapped into a locking hole, and the top end of the detection needle is located within a limiting component.
[0015] As a further embodiment of the present invention: a spring is sleeved on the probe tip, the top end of the spring is fixedly connected to the bottom end of the fixing sleeve, the bottom end of the spring is fixed to the fixing ring, the fixing ring is snapped onto the outside of the probe tip, and a contact ring is provided at the bottom of the probe tip.
[0016] As a further aspect of the present invention: the limiting component includes an air cushion cylinder, which is snapped into a fixed sleeve. The air cushion cylinder is provided with a plurality of anti-slip rings. The top of the probe is sleeved inside the air cushion cylinder. The top of the air cushion cylinder is connected to an air guide tube, and the top end of the air guide tube passes through the support seat and communicates with the cavity.
[0017] As a further aspect of the present invention: the adjusting assembly includes a piston cylinder, which is snapped onto one side of the support base and communicates with the cavity. A piston plate is provided inside the piston cylinder, and a lead screw is connected to one side of the piston plate via a bearing. A nut is externally threaded onto the lead screw, and the nut is snapped onto the side of the piston cylinder away from the support base. A rotating handle is fixedly connected to the end of the lead screw away from the piston cylinder.
[0018] As a further aspect of the present invention: the cavity is annular in design, and the main body of the multi-channel sensor alarm is provided with several heat sinks, and mounting brackets are provided on both sides of the main body of the multi-channel sensor alarm.
[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0020] 1. In this invention, a storage box is used to store the probes. When using the multi-channel sensor alarm, the main body of the multi-channel sensor alarm is placed on the surface or inside of the object to be measured, so that multiple probes come into contact with the surface to be measured. Since the probes can freely extend and retract within the storage box, multiple probes can be arranged according to the shape of the surface to be measured. The spring force supports the fixing ring and the probes, allowing the probes to fit tightly against the surface to be measured. Then, the handle is adjusted so that the handle drives the lead screw to rotate and move closer to the support base. The lead screw, through the bearing, drives the piston plate to move within the piston cylinder. Because the volume of the cavity inside the support base is reduced, the gas inside the cavity can enter the air cushion cylinder through several air guide tubes, causing the air cushion cylinder to expand. This, in turn, causes multiple anti-slip rings to fit tightly against the outside of the probe, thus achieving the purpose of limiting the probe and keeping it in its current extension / retraction position. Then, the main body of the multi-channel sensor alarm is installed on the object to be measured, preventing the probe from moving freely and affecting normal detection work. This ensures that the detection end of the main body of the multi-channel sensor alarm can make full contact with the detection surface, facilitating installation while reducing data errors and improving the monitoring accuracy of the main body of the multi-channel sensor alarm.
[0021] 2. In this invention, the detection needle is limited by a limiting component. Combined with the air cushion and anti-slip ring, this not only secures the detection needle but also prevents damage and provides good insulation. When adjusting the position of the detection needle, or when removing the multi-channel sensor alarm body, the handle is rotated in the opposite direction, causing the lead screw to move the piston plate towards the edge of the support base. As the inner container of the cavity expands, the multiple air cushions, due to their elasticity, can expel the gas, which can then enter the cavity through the air guide tube. At this point, the air cushions return to their original shape, causing the anti-slip ring and air cushions to detach from the detection needle. With the support of the spring, the detection needle extends outward from the air cushion. At this point, multiple detection needles are in the same extension / retraction position, allowing the multi-channel sensor alarm body to be installed and monitored again, thus greatly facilitating the monitoring work.
[0022] 3. In this invention, multiple detection components are connected by setting a detection motherboard. The detection motherboard can transmit signals to the detection needles through a conductive sleeve, and the detection needles can slide up and down inside the conductive sleeve. Therefore, it is not necessary to use a multi-strand wire connection method, which prevents the extension and retraction of the detection needles from pulling the wires and affecting the normal transmission of data. Furthermore, the middle part of the detection motherboard is connected to the access terminal of the multi-channel sensor alarm body through a signal post, so that the detection motherboard can integrate the data detected by all the detection needles and transmit this data to the multi-channel sensor alarm body. This greatly simplifies the assembly steps of the alarm, reduces the workload, and improves the stability of the alarm operation. Attached Figure Description

[0032] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0033] like Figure 1-8 As shown, the present invention provides a technical solution: a multi-channel sensor alarm based on NB-IoT and controlled by Bluetooth, including a multi-channel sensor alarm body 1, a support base 2 at the bottom of the multi-channel sensor alarm body 1, a Bluetooth module inside the multi-channel sensor alarm body 1, the multi-channel sensor alarm body 1 adopts NB-IoT / 3G / 4G / 5G link transmission, and can be remotely controlled via Bluetooth. The Bluetooth module can control the alarm through remote signal transmission, and the multi-link transmission method can expand the function of the alarm and improve the stability of data transmission.
[0034] The support base 2 is fixed to the storage box 3. The storage box 3 contains a conductive component 4. The middle part of the conductive component 4 passes through the storage box 3 and the support base 2 and connects to the access terminal at the bottom of the multi-channel sensor alarm body 1. The conductive component 4 includes a detection main board 401, which is snapped into the storage box 3. The detection main board 401 has several slots 402, and the detection component 5 is snapped into each slot 402. A signal wire post 403 is located in the middle of the detection main board 401, and an insulating sleeve 404 is fitted over the signal wire post 403. The insulating sleeve 404 is snapped into the middle of the support base 2. The signal wire post 403 passes through the support base 2 and connects to the multi-channel sensor... The bottom of the alarm body 1 is connected to the input terminal. Through the cooperation between the detection motherboard 401 and the signal terminal 403, the detection motherboard 401 connects to multiple detection components 5. The detection motherboard 401 can transmit signals to the detection needles 503 through the conductive sleeve 501. The middle part of the detection motherboard 401 is connected to the input terminal of the multi-sensor alarm body 1 through the signal terminal 403. This allows the detection motherboard 401 to integrate the data detected by all the detection needles 503 and transmit this data to the multi-sensor alarm body 1, which greatly simplifies the assembly steps of the alarm and improves the stability of the alarm operation.
[0035] The conductive component 4 is provided with several detection components 5, which pass through the storage box 3. The top of the detection component 5 is sleeved in the fixing sleeve 6. The detection component 5 includes a detection needle 503, and a conductive sleeve 501 is sleeved on the detection needle 503. The conductive sleeve 501 is snapped into the slot 402. The top of the detection needle 503 is located in the limiting component 7. Through the setting of the conductive sleeve 501, the detection needle 503 can transmit signals through the conductive sleeve 501. The detection needle 503 can slide up and down in the conductive sleeve 501. Therefore, it is not necessary to use a multi-strand wire connection method to prevent the extension and retraction of the detection needle 503 from pulling the wire and affecting the normal transmission of data.
[0036] A spring 502 is fitted over the probe 503. The top end of the spring 502 is fixedly connected to the bottom end of the fixing sleeve 6, and the bottom end of the spring 502 is fixed to the fixing ring 504. The fixing ring 504 is snapped onto the probe 503. A contact ring is provided at the bottom of the probe 503. By setting the spring 502, the elastic force of the spring 502 supports the fixing ring 504 and the probe 503, so that the probe 503 can fit tightly against the surface to be tested, and the detection end of the multi-channel sensor alarm body 1 can make full contact with the detection surface. When the limiting component 7 is disengaged from the probe 503, the probe 503 extends outward from the air cushion 701 in conjunction with the supporting effect of the spring 502. At this time, multiple probes 503 are in the same extension and retraction position, so that the multi-channel sensor alarm body 1 can perform the next installation and monitoring work.
[0037] The fixing sleeve 6 is set at the top inside the storage box 3. The fixing sleeve 6 is snapped into the limiting component 7. The top of the detection component 5 is located inside the limiting component 7. The limiting component 7 includes an air cushion cylinder 701, which is snapped into the fixing sleeve 6. The air cushion cylinder 701 is provided with several anti-slip rings 702. The top of the detection needle 503 is sleeved inside the air cushion cylinder 701. The top of the air cushion cylinder 701 is connected to the air guide tube 703. The top end of the air guide tube 703 passes through the support seat 2 and communicates with the cavity 8. Through the setting of the air cushion cylinder 701 and the anti-slip rings 702, the gas in the cavity 8 can enter the air cushion cylinder 701 through several air guide tubes 703, causing the air cushion cylinder 701 to expand. This causes the multiple anti-slip rings 702 to fit tightly against the outside of the detection needle 503, thus achieving the purpose of limiting the detection needle 503 and keeping the detection needle 503 in its current extension and retraction position, preventing the detection needle 503 from moving freely and affecting normal detection work.
[0038] The support base 2 has a cavity 8, which communicates with the tops of several limiting components 7. Adjusting components 9 are provided on both sides of the support base 2, and are connected to the cavity 8. Each adjusting component 9 includes a piston cylinder 901, which is engaged with one side of the support base 2 and communicates with the cavity 8. A piston plate 902 is provided inside the piston cylinder 901. A lead screw 903 is connected to one side of the piston plate 902 via a bearing. A nut 904 is threaded onto the lead screw 903, and is engaged with the side of the piston cylinder 901 away from the support base 2. The end of the lead screw 903 away from the piston cylinder 901 is fixedly connected to… With a handle 905, the screw 903 and piston plate 902 cooperate with each other. The screw 903 drives the piston plate 902 to move in the piston cylinder 901 through the bearing, which reduces the volume of the cavity 8 in the support seat 2. This allows the gas in the cavity 8 to be introduced into the air cushion cylinder 701, making it easier to adjust the state of the air cushion cylinder 701. Furthermore, the screw 903 and nut 904 cooperate with each other. The threaded connection also serves to position the screw 903 and piston plate 902, preventing the piston plate 902 from sliding freely in the piston cylinder 901 and affecting the normal introduction or export of airflow.
[0039] The cavity 8 is a ring-shaped design, and the main body 1 of the multi-channel sensor alarm is equipped with several heat sinks 10. Mounting brackets are provided on both sides of the main body 1 of the multi-channel sensor alarm. Because the cavity 8 is a ring-shaped design, the middle part of the support base 2 is solid, which can connect the signal post 403 and the insulating sleeve 404, providing good support and improving the overall stability of the alarm. In addition, the cavity 8 on the support base 2 can also play a certain role in heat insulation, preventing heat from the test surface from being directly transferred to the main body 1 of the multi-channel sensor alarm. Because of the heat sinks 10, the arrangement of multiple heat sinks 10 can increase the heat conduction area and improve the heat dissipation effect of the main body 1 of the multi-channel sensor alarm.
[0040] The working principle of this invention is as follows:
[0041] In use, place the main body 1 of the multi-channel sensor alarm on the surface or inside of the object to be tested, so that multiple probes 503 come into contact with the surface to be tested. Since the probes 503 can extend and retract freely in the storage box 3, the multiple probes 503 can be arranged according to the shape of the surface to be tested. The spring force of the spring 502 supports the fixing ring 504 and the probes 503, so that the probes 503 can fit tightly with the surface to be tested.
[0042] Adjust the handle 905 again, so that the handle 905 drives the lead screw 903 to rotate and move closer to the support seat 2. The lead screw 903 drives the piston plate 902 to move in the piston cylinder 901 through the bearing. Since the volume of the cavity 8 in the support seat 2 becomes smaller, the gas in the cavity 8 can enter the air cushion cylinder 701 through several air guide tubes 703, causing the air cushion cylinder 701 to expand and drive multiple anti-slip rings 702 to fit tightly against the outside of the detection needle 503. Thus, the purpose of limiting the detection needle 503 can be achieved, so that the detection needle 503 maintains its current extension and retraction position. Then, install the multi-channel sensor alarm body 1 on the object to be tested.
[0043] The detection motherboard 401 connects to multiple detection components 5. The detection motherboard 401 can transmit signals to the detection needles 503 through the conductive sleeve 501. The detection needles 503 can slide up and down inside the conductive sleeve 501. The middle part of the detection motherboard 401 is connected to the access end of the multi-channel sensor alarm body 1 through the signal post 403, so that the detection motherboard 401 can integrate the data detected by all the detection needles 503 and transmit the data to the multi-channel sensor alarm body 1.
[0044] When the main body 1 of the multi-channel sensor alarm is removed, the handle 905 is rotated in the opposite direction, causing the lead screw 903 to drive the piston plate 902 to move towards the edge of the support seat 2. When the contents of the cavity 8 become larger, the multiple air cushions 701 can squeeze out the gas due to their own elasticity. The gas can enter the cavity 8 through the air guide tube 703. At this time, the air cushions 701 return to their original shape, causing the anti-slip ring 702 and the air cushions 701 to separate from the detection needles 503. With the support of the spring 502, the detection needles 503 extend outward from the air cushions 701. At this time, the multiple detection needles 503 are in the same extension and retraction position.
