Description

Technical Field

[0001] This invention is a valve I / O status monitoring terminal, belonging to the field of monitoring devices. Background Technology

[0002] The core value of fire monitoring devices lies in using technology to make up for the shortcomings of traditional fire protection, accurately addressing key pain points such as delayed fire warnings, blind spots in risk monitoring, and low efficiency in emergency response; at the same time, relying on modern sensing technology, they achieve the fire warning goal of "early detection, early warning, and early response".

[0003] In actual monitoring, multiple sets of monitoring sensors need to be deployed for each scenario to collect two key data points in real time: valve opening status and ambient temperature. However, there are two key points to note in current applications: the number of monitoring points is large, and if a sensor malfunctions, it must be checked and replaced immediately. Only in this way can the risk of false alarms be effectively avoided, ensuring the accuracy of monitoring data and the reliability of early warnings. Furthermore, some sensors may experience communication interruptions due to transient lock-up of the interface circuit after encountering static electricity or surges. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a valve I / O status monitoring terminal to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a valve I / O status monitoring terminal, comprising: a protective housing, inside which a main board and a battery are installed; a nested sealing plate is mounted on the surface of the protective housing; an outer cover is also mounted on the surface of the protective housing, forming a cavity that seals the main board and the battery; the protective housing has a shell, around which a main line interface and a sensor interface are arranged; the main line interface and the sensor interface are connected to the main board via wires; the sensor interface is fixed to the shell via an inner connector; the port of the inner connector has a detachable outer connector; a movable adjusting rod is provided inside the positioning connector of the inner connector; the adjusting rod is driven by a reducer installed at the bottom of the positioning connector, and the reducer controls the distance between the adjusting rod and the outer connector.

[0006] Preferably, the motherboard is connected to a host computer via a sensor interface and communicates with an IoT platform through the host computer. The motherboard is connected to a sensor via the sensor interface. When the valve is opened, the switch signal is disconnected, triggering the motherboard to upload "disconnection information" data to the host computer. When the valve is closed, the switch signal is closed, triggering the motherboard to upload "closure information" data to the host computer. The host computer receives the valve status information uploaded by the motherboard.

[0007] Preferably, the positioning joint includes a connecting column, an insulating column is provided inside the slot opening in the middle of the connecting column, a rotating central shaft connected to the reducer is provided in the middle of the insulating column, a limiting frame for restricting the rotating central shaft is also provided on one side of the connecting column, the main shaft of the reducer is connected to the rotating central shaft, the rotation of the rotating central shaft is controlled by the reducer, and the insulating column is provided with a sliding groove, which is movably connected to the adjusting rod.

[0008] Preferably, the adjusting rod includes a first ring, a first threaded ring in the middle of the first ring, meshing teeth inside the first ring, and a second ring parallel to each other at the bottom of the first ring. The second ring is connected to the first ring through a sliding ring fixed to its surface. The sliding ring and the first ring are rotatably engaged. The second ring is also provided with a rotatable contact rod, and the second ring engages with the meshing teeth for transmission.

[0009] Preferably, the contact rod includes a driving tooth, which is connected to a connecting rod. The connecting rod is movably connected to an insulating post through a surface-nested movable sleeve post.

[0010] Preferably, the surface of the connecting rod is provided with a protrusion that engages with the groove inside the movable sleeve.

[0011] Preferably, the contact surface between the connecting rod and the external connector is provided with a side groove.

[0012] Preferably, the movable sleeve is provided with a contact point welded to the movable sleeve, and a wire is connected through the contact point.

[0013] Preferably, the meshing teeth are symmetrically arranged on the inner wall of the first ring, and the surface of the first ring without meshing teeth is disengaged from the driving teeth of the contact rod. Preferably, the rotating central shaft is a two-section structure, with one section fixed to the middle of the connecting column and the other section being a toothed column with external threads that mesh with the first threaded ring.

[0014] Preferably, a detection switch is provided between the protective shell and the outer cover to detect the connection status between the outer cover and the protective shell.

[0015] The valve I / O status monitoring terminal of this invention has the following advantages: The improved device addresses the interface oxidation problem and protects contacts by using the external and internal connectors of the sensing interface in conjunction with a positioning connector. The adjusting rod inside the positioning connector is designed as a movable structure, and its movement is controlled by a reducer at the bottom, enabling automatic separation and contact of the contacts. This not only avoids oxidation and poor contact caused by prolonged connection and heat, but also allows the connecting rod to retract when not connected, thus protecting it. Furthermore, the connecting rod and the protrusion are made of conductive material, and the welded contact points on the outer ring of the protrusion facilitate wiring and ensure stable conductivity. The optimized device can unlock the locked state upon power failure and reconnection, and can coordinate with the host computer and platform in the fire protection system to ensure system stability. It also assists the host computer in processing information and the platform in filtering alarm information. The status locking mechanism prevents repeated alarms and significantly reduces the false alarm rate. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] With a large number of existing monitoring points, if a sensor malfunctions, it must be investigated and replaced immediately. Only in this way can the risk of false alarms be effectively avoided, ensuring the accuracy of monitoring data and the reliability of early warnings. Furthermore, some sensors may experience communication interruptions due to temporary lock-up of the interface circuit after encountering static electricity or surges. Therefore, to solve the above problems, this paper proposes the following technical solution: Please see Figures 1 to 7This invention provides a valve I / O status monitoring terminal technical solution: its structure includes: a protective shell 1, inside which a main board 3 and a battery 5 are installed, the surface of the protective shell 1 is equipped with a nested sealing plate 2, and the surface of the protective shell 1 is also equipped with an outer cover 6, the outer cover 6 and the protective shell 1 forming a cavity that seals the main board 3 and the battery 5, the protective shell 1 is provided with a housing 11, around which a main line interface 12 and a sensing interface 13 are provided, the main line interface 12 and the sensing interface 13 are connected to the main board 3 by wires, the sensing interface 13 is fixed to the housing 11 by an inner connector 132, the port of the inner connector 132 is provided with a detachable outer connector 131, the positioning connector 321 of the inner connector 132 is provided with a movable adjusting rod 322, the adjusting rod 322 is driven by a reducer 323 installed at the bottom of the positioning connector 321, and the reducer 323 controls the distance between the adjusting rod 322 and the outer connector 131.

[0028] When in use, the main structure of this device includes a housing formed by a protective shell 1 and an outer cover 6. A sealing plate 2 is provided at the opening of the protective shell 1 to seal and block the communication port of the main board 3, which facilitates subsequent program debugging and problem detection. A detection switch 4 is used between the protective shell 1 and the outer cover 6 to prevent malicious opening and damage. A sealing ring is also provided between the protective shell 1 and the outer cover 6. The main board 3 is installed inside the protective shell 1, and a battery 5 for emergency power supply is provided. The main board 3 is installed inside the housing 11 of the protective shell 1. The main line interface 12 and the sensor interface 13 located on the side of the main board 3 are used to connect the main control cable and the sensor, respectively.

[0029] The connection method of this device is as follows: the motherboard 3 is wired to the host computer through the main line interface 12, which can not only transmit signals stably, but also provide a more stable power supply. The host computer is connected to the fire protection IoT platform for convenient control. It can not only transmit operation and maintenance messages through the administrator, but also authorize users to control it, which is convenient for maintenance.

[0030] The motherboard 3 connects to sensors via sensing interface 13. Multiple sensing interfaces 13 can be configured as needed to facilitate the detection of various states of a single device, such as the opening and closing status of a valve and its internal temperature, thereby improving operational stability. (Reference) Figure 7 .

[0031] When the valve is opened, this device disconnects the switch signal, triggering the main board 3 to upload "disconnection information" data to the host computer. When the valve is closed, it closes the switch signal, triggering the main board 3 to upload "closure information" data to the host computer. By collecting valve status changes in real time, the main board 3 transmits the data to the host computer. If the information has not been sent to the fire protection IoT platform, it sends the data to the platform receiving device via the MODBUS protocol, recording the sending status as "sent". After receiving the data, the platform returns a reception information via the HTTP interface, and the host computer records "platform received", ensuring that each valve status information is sent only once to avoid duplicate alarms.

[0032] The host computer decides whether to forward data based on whether the information has already been sent to the platform to avoid duplicate alarms. The host computer records the sending status of each message to ensure that the same message is sent only once. The platform uses an encoding locking mechanism to ensure that unprocessed or pending alarms are not received repeatedly. The platform introduces an administrator password verification mechanism to ensure that only authorized personnel can complete the alarm processing. The on-duty personnel and management personnel have clear division of labor. On-duty personnel process the alarms to the "pending processing" status, and management personnel complete the final processing.

[0033] For non-alarm valves already in use, simply installing a valve I / O action monitor will enable the alarm function without interruption or modification. Combining it with this device will make management and maintenance more convenient.

[0034] The sensing interface 13 is provided with an external connector 131 and an internal connector 132. The internal connector 132 is set as a base on the side of the housing 11. In order to solve the problem of poor contact due to oxidation caused by heat generation of the surface interface after long-term connection, the adjusting rod 322 inside the positioning connector 321 is set as a movable structure. It is controlled by the reducer 323 at the bottom. The reducer 323 controls the movement of the adjusting rod 322 to achieve automatic separation and contact of the contacts. This not only avoids oxidation, but also allows the connecting rod 262 to retract for protection when not connected.

[0035] Among them, reducer 323 is a reducer unit, which is driven by a geared motor and is easy to control.

[0036] A limiting frame 212 for support is provided on one side of the connecting post 211 of the positioning joint 321. A rotatable rotating central shaft 214 is designed between the limiting frame 212 and the insulating post 213 in the middle of the connecting post 211. The rotation of the rotating central shaft 214 causes the threaded adjustment rod 322 on the surface of the rotating central shaft 214 to move axially, thereby facilitating displacement.

[0037] Furthermore, the through-type sliding groove 215 of the insulating column 213 cooperates with the adjusting rod 322 to ensure the smooth movement of the adjusting rod 322 and prevent deformation.

[0038] Regarding the structure of the adjusting rod 322, the adjusting rod 322 includes a rotating first ring 221. The first ring 221 engages with the threaded post of the rotating central shaft 214 through a first threaded ring 222. The first ring 221 has meshing teeth 223 inside, which drive the contact rod 226 to rotate. In order to better control the rotation of the contact rod 226, the first ring 221 is set on the surface of the sliding ring 225 of the second ring 224. The sliding ring 225 is nested with the first ring 221 and can only rotate. When rotating, the first ring 221 can drive the second ring 224 to move through the sliding ring 225, thereby driving the contact rod 226 to separate from the outer connector 131.

[0039] The meshing teeth 223 inside the first ring 221 are partially toothed. When rotating, the driving teeth 261 of the drive contact rod 226 rotate. After the rotation exceeds the meshing range, it stops rotating to avoid excessive friction of the connecting rod 262 and poor contact.

[0040] To reduce problems, the connecting rod 262 is further optimized. The connecting rod 262 is provided with a side groove 265 to scrape off the oxide layer on the contact surface. The connecting rod 262 is also provided with a movable sleeve post 263 for fitting. A protrusion 264 is provided in the middle of the connecting rod 262. The protrusion 264 engages with the movable sleeve post 263. When rotating, the movable sleeve post 263 acts as a sleeve shaft to reduce resistance.

[0041] Furthermore, due to the gap between the movable sleeve 263 and the connecting rod 262, when the first ring 221 rotates and abuts the drive tooth 261, the connecting rod 262 expands outward, which can better engage with the internal contact of the outer connector 131.

[0042] The connecting rod 262 and the protrusion 264 are made of conductive material, and the outer ring of the protrusion 264 is welded to the contact point 266 for conduction, which facilitates wiring.

[0043] The drive teeth 261 driven by the meshing teeth 223 inside the first ring 221 can not only remove impurities from the contact surface between the connecting rod 262 and the external surface, but also remove impurities from the contact between the connecting rod 262 and the protrusion 264.

[0044] The improved device addresses the interface oxidation problem and protects the contacts by using the following design: the outer connector 131 and inner connector 132 of the sensing interface 13 work in conjunction with the positioning connector 321. The adjusting rod 322 inside the positioning connector 321 is designed as a movable structure. The movement of the adjusting rod 322 is controlled by the reducer 323 at the bottom, which enables automatic separation and contact of the contacts. This not only avoids oxidation and poor contact caused by heat from prolonged connection, but also allows the connecting rod 262 to retract when not connected, thus protecting the connecting rod 262. In addition, the connecting rod 262 and the protrusion 264 are made of conductive material, and the solder contact point 266 on the outer ring of the protrusion 264 facilitates wiring and ensures stable conductivity.

[0045] Through the collaborative work of front-end equipment, host computer, platform receiving device, and fire protection IoT platform, real-time monitoring, refined management, and standardized processing of fire pipeline valve status are achieved, effectively solving problems such as high false alarm rate, extensive management, and non-standard handling procedures in traditional systems. The above description only outlines the basic principles and preferred embodiments of the present invention. Those skilled in the art can make many changes and modifications based on the above description, and these changes and modifications should fall within the protection scope of the present invention.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
