Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of informationization improvement of traditional components, and particularly relates to an intelligent sensing device for multi-scene handle components. BACKGROUND

[0002] With the development of industrial production informatization, the use of some traditional mechanical structural components still stays in the original use mode. Although the structure is excellent and irreplaceable, it has entered the big data era, and the traditional mechanical structural components need to be informatized, visualized and supervised. Therefore, increasing intelligence and informatization is an inevitable trend of industrial upgrading. The core purpose is to improve efficiency, accuracy, self-adaptability and interconnection ability through technology integration, so as to meet the complex needs of modern industry.

[0003] The auxiliary components commonly used in industrial production process include control rods, hooks and handles. They are all traditional mechanical structures, but they are related to many important links in the production process and need to perceive their use state to provide strong help for informatization, fine production arrangement and supervision. SUMMARY

[0004] The purpose of the present application is to provide an intelligent sensing device for multi-scene handle components. The traditional mechanical structure control rod, hook and handle are intelligently and informatizedly transformed, a pinch sensing device is added at the handle component, the traditional mechanical structure is evolved into a "networked intelligent node", the data value is released, the operation state is monitored in real time, the operation is assisted, the mistakes are reduced, and the work efficiency is improved.

[0005] The present application is realized by the following technical scheme: An intelligent sensing device for multi-scene handle components, comprising a sensing and identifying device, a grip plate and a fixing seat. The sensing and identifying device is hingedly connected to one end of the grip plate, and a microcontroller, a battery, a communication module and an audible and visual alarm module are further arranged in the sensing and identifying device. The microcontroller is electrically connected to the battery, the communication module and the audible and visual alarm module. The fixing seat is connected to the bottom of the sensing and identifying device by bolts, and is used for fixing the device to the handle component to be adapted. The other end of the grip plate is a force sensing area, and a gasket type pressure sensor is arranged in the force sensing area. The microcontroller is further electrically connected to the gasket type pressure sensor through a connecting line to obtain a grip pressure signal. The communication module can transmit signals and receive alarm instructions, and the audible and visual alarm module is controlled to start.

[0006] In the present scheme, the inductive recognition device is hingedly designed with the grip plate, and the bottom is fixed on the fixed seat through bolt connection. It can not only ensure that the fixed seat is stable and fixed on the control rod, hook, door handle and other different grip handle components to be adapted, but also can be flexibly matched with the shape profile of various grip handles by means of the hinged structure, so as to ensure that the gasket type pressure sensor of the force sensing area of the other end of the grip plate can capture the gripping action. The microcontroller, battery, communication module and sound and light alarm module are arranged in the inductive recognition device. The independent and stable power supply can be realized by the battery without relying on external power supply. The microcontroller can obtain the gripping pressure signal collected by the gasket type pressure sensor in real time through the connecting line, and then the signal can be efficiently transmitted to the mobile terminal or the background management terminal through the communication module, so as to break through the limitation of "isolated and no data feedback" of traditional grip handle components, realize the informatization and visualization of grip handle use state, and realize the informatization and visualization of grip handle use state. At the same time, when the signal transmission is abnormal, the communication module can receive the alarm instruction, the microcontroller can quickly control the sound and light alarm module to start, and timely remind the operator to correct the operation, reduce the production risk or use hidden danger caused by operation mistake. The overall structure does not need to be connected with complex auxiliary equipment, which simplifies the intelligent transformation process of traditional grip handle components, reduces the transformation cost, and can be widely adapted to grip handle components in industrial production, home security, public facilities and other scenes, greatly improves the universality and practicality of the device, and finally promotes the traditional mechanical grip handle from single execution function to "networked intelligent node", releases the data value to assist fine management, and effectively improves the efficiency and safety of related operation.

[0007] As a further scheme of the intelligent sensing device, the bottom of the grip plate is provided with a bottom plate, the bottom plate is provided with a hole, and the gasket type pressure sensor is embedded in the hole to form positioning and limiting of the gasket type pressure sensor, avoid shaking and displacement of the sensor during device disassembly, transportation or use, ensure the stability of signal transmission between the sensor and the microcontroller through the connecting line, reduce the signal acquisition error caused by the position deviation of the sensor, and the sensing end of the gasket type pressure sensor protrudes from the bottom surface of the bottom plate, which can ensure that the sensor can directly contact the gripping part of the operator or the surface of the grip handle when the device is adapted to the control rod, hook, door handle and other different grip handle components to be adapted, and avoid the blocking or attenuation of the pressure signal by the bottom plate material.

[0008] As a further scheme of the intelligent sensing device, the device further comprises a key switch electrically connected to the microcontroller, and the key switch can be matched with a trigger contact of a to-be-fitted handle component to detect the contact or disengagement state of the trigger contact. When the key switch detects that the trigger contact is disengaged and the mobile terminal or the background determines that the handle component is in an abnormal state (e.g., the hook is not closed), the audible and light alarm module can be triggered to timely remind the operator to correct, effectively reducing the operation errors caused by abnormal contact matching, and assisting the traditional handle component to upgrade from “single mechanical execution” to “multi-dimensional intelligent monitoring” networked intelligent node.

[0009] As a further scheme of the intelligent sensing device, when the sensing and identifying devices are multiple, each sensing and identifying device can communicate with the same mobile terminal through a respective communication module. The mobile terminal can number each sensing and identifying device, so that the background management terminal can quickly associate the number with the handle component state through the mobile terminal, and preset a holding identification sequence to avoid production process disorder, equipment failure or safety risk caused by misoperation of the operator. If it is identified that the handle is not held in the preset sequence, an alarm instruction can be sent to the corresponding sensing and identifying device to trigger the audible and light alarm module to immediately remind the operator to quickly detect and correct the error, reduce downtime or rework caused by sequence errors, and further improve the operation efficiency.

[0010] As a further scheme of the intelligent sensing device, if the key switch detects that the trigger contact of the to-be-fitted handle component is disengaged, and the mobile terminal determines that the to-be-fitted handle component is in an unclosed state, the microcontroller can send an abnormal signal to the mobile terminal through the communication module and trigger the audible and light alarm module. By detecting the disengagement state of the trigger contact through the key switch and combining the determination of the mobile terminal that the handle component is “unclosed”, double verification is formed to accurately distinguish between “temporary contact deviation of the contact” and “actual unclosed”, effectively avoiding false alarms that may be caused by single contact detection, ensuring the accuracy of abnormal identification, and solving the problem that the traditional handle component only relies on mechanical structure and cannot determine whether the disengagement of the contact is accompanied by functional failure.

[0011] As a further scheme of the intelligent sensing device, the fixed seat and the sensing and identifying device are connected through a quick disassembly and assembly mechanism, which includes but is not limited to a buckle structure and a magnetic attraction structure. Without the need to redesign or replace the fixing structure for different handle components, the universality and use cost-effectiveness of the device are significantly improved.

[0012] As a further scheme of the intelligent sensing device, the signals transmitted by the microcontroller through the communication module include the holding signals collected by the gasket type pressure sensor and the device working state signals, so that the manager can timely grasp the health status of the device itself. The communication module can also receive a control signal forwarded by the background management end through the mobile terminal, and the control signal includes a parameter configuration signal and an alarm threshold setting signal, so that the use requirements of different handle components can be flexibly adapted without disassembling the device, the multiplexing efficiency of the device in multiple scenes is greatly improved, and the poor scene adaptability caused by fixed parameters is avoided.

[0013] As a further scheme of the intelligent sensing device, the gasket type pressure sensor is a piezoelectric pressure sensor or a thin film pressure sensor, and the sensing range of the sensor can be configured by the microcontroller, so that the sensitivity can be adjusted according to different scene requirements without disassembling the device or replacing hardware.

[0014] As a further scheme of the intelligent sensing device, the handle plate is adapted to the shape of the handle component to be adapted, and the handle plate and the handle component to be adapted are parallelly attached, so that the gasket type pressure sensor in the force sensing area of the handle plate always maintains a stable relative position with the handle or the holding part of the operator, and the pressure signal collection missed detection or false detection caused by loose attachment or angle deviation is avoided.

[0015] As a further scheme of the intelligent sensing device, the microcontroller in the sensing and recognizing device is also connected to an external triggering component through a second connection line, the second connection line is arranged through the handle plate, and the tail bottom edge of the handle component to be adapted is provided with a concave wire protection plate, the second connection line is arranged in the wire protection plate, so that physical protection is formed on the wire, and external influences such as dust, oil stains and collision in industrial production, public facility use and other scenes are effectively isolated.

[0016] Compared with the prior art, the present application has the following advantages and beneficial effects: The present application can stably adapt to industrial control rods, hooks, safety door handles, lock catches, plate hooks and other types of handle components through the hinged design of the sensing and recognizing device and the handle plate, the flexible fixing structure of the fixing seat, the shape adaptation and parallel attachment design of the handle plate and the handle component, without the need to design a device for different scenes, greatly improving the multiplexing in multiple scenes, solving the problem of narrow scene adaptation range and poor universality in the prior art; The present application collects the holding signal through the gasket type pressure sensor in the force sensing area of the handle plate, detects the trigger contact state in combination with the key switch, processes the signal through the microcontroller, transmits the signal to the mobile terminal and the background management end through the communication module, receives the control signal configuration parameter forwarded by the background, upgrades the traditional handle from a "isolated execution unit" to a "networked intelligent node", releases the data value of the use state and the device running state, provides data support for fine arrangement of industrial production and operation supervision, and makes up for the defects of informationization and visualized supervision in the prior art; The application can also number and preset the holding sequence of multiple induction recognition devices, trigger sound and light alarm when not holding in sequence, and also remind the operator in time through the sound and light alarm module when the contact point is detected by the key switch to be separated and the handle is not closed, and send an abnormal signal to the background, effectively reducing production disorder or safety hazards caused by incorrect operation sequence and abnormal contact matching, and improving operation safety and accuracy; The application also realizes convenient disassembly and assembly of the induction recognition device and the fixing seat through the buckle, magnetic attraction and other quick disassembly and assembly mechanisms, which can be completed without tools, and the second connecting line passes through the grip plate and is protected by the concave wire protection plate, avoiding line wear and breakage, improving device disassembly and maintenance efficiency, and ensuring signal transmission stability, solving the problems of low disassembly and assembly efficiency and insufficient line protection in the prior art.
