Description

Technical Field

[0001] The utility model relates to the technical field of microelectronics, and specifically relates to a fault shutdown warning device. Background Art

[0002] Fault shutdown usually occurs in mechanical equipment with an electric drive structure, such as industrial or household electrical appliances like printing presses, crushers, vacuum cleaners, dishwashers, etc. When the output end of the motor is locked, since electrical energy cannot be converted into mechanical energy at the output end of the motor, almost all of the electrical energy is converted into heat energy, causing the temperature at the output end of the motor to rise sharply. Existing shutdown warning devices often monitor the temperature change rate at the output end of the drive structure and send warning signals to achieve the function of fault shutdown warning. However, since it is difficult for existing warning measures to distinguish whether the fault is caused by a circuit fault or a mechanical structure breakdown, the maintenance time is long. Therefore, we propose a fault shutdown warning device that can distinguish the cause of the fault and shorten the maintenance duration. Content of the Utility Model

[0003] The purpose of the utility model is to provide a fault shutdown warning device to solve the problems raised in the above background art.

[0004] To achieve the above object, the present utility model provides the following technical solutions: A fault shutdown warning device includes an insulating box, which serves as the external protection and insulation structure of the warning device. The interior of the insulating box is divided into a first cavity and a second cavity by a partition. A controller is installed in the first cavity through a bracket. The input end of the controller is electrically connected to a temperature sensor and a sound sensor, and the output end of the controller is connected to an alarm component. The temperature sensor collects the surface temperature of the equipment connected to the warning device and the change of the temperature. The sound sensor is used to collect the sound information at the fault location of the equipment connected to the warning device. The temperature sensor converts the collected temperature data into a digital signal recognizable by the controller through an analog-to-digital conversion module. At the same time, the sound sensor converts the collected pitch and loudness signals into digital signals, and further amplifies them through an amplifier. The amplified temperature and sound signals are respectively compared with preset standard values through a comparator. The comparator sends the comparison result to the controller. The judgment unit in the controller judges the fault source and sends the judgment result to the display screen for display. When the judgment result is a circuit fault or a mechanical fault, the alarm component alarms through sound or light. When the temperature signal reaches the warning value and the sound signal is within the preset value range, it is judged as a circuit fault. When both the temperature signal and the sound signal reach the warning value, it is judged as a mechanical fault. When the driving part of the mechanical equipment has a locking fault, noise will be generated, causing the sound signal to exceed the preset value. Thus, the fault source can be judged by synchronously collecting temperature and sound data, which is beneficial to improving the maintenance efficiency. The top of the temperature sensor is electrically connected to a power supply through a terminal block. The power supply provides electrical energy support for the warning device. The power supply is powered by the power grid or solar energy. The top of the temperature sensor is connected to a display screen, which is used to display the temperature of the fault location of the faulty equipment and the sound decibels and loudness generated at the fault location. The bottom of the temperature sensor is connected to a temperature acquisition probe through a deformable flexible tube. The temperature acquisition probe is fixed to the surface of the fault occurrence location of the equipment to be detected. The top of the sound sensor is connected to a wire duct. The lower end of the wire duct is detachably connected to a sound pickup microphone, which is used to collect the pitch and loudness information of the fault location of the equipment.

[0005] As a further solution of the present utility model: The insulating box includes a box body and a box cover fixed on the top of the box body. Four corner ends of the bottom of the box body are respectively welded with connecting rods having threaded holes. The insulating box can perform dust-proof, anti-collision and insulation protection on its internal components.

[0006] As a further solution of the utility model: the controller is an AT89C51 single-chip microcomputer, the temperature sensor is a surface thermal resistance or a surface thermocouple sensor, the sound sensor includes a pitch signal acquisition unit and a loudness signal acquisition unit, the temperature sensor is used to collect the temperature at the equipment failure point. During installation, the temperature acquisition probe of the temperature sensor is fixedly connected to the pre-failure part of the equipment. The pre-failure part of the equipment with a driving component is usually the output end of a motor, a servo or a motor.

[0007] As a further solution of the utility model: the power supply is a solar cell, the solar cell includes a battery pack, the battery pack is fixed inside the second cavity, the top of the battery pack is electrically connected to a solar panel, one end of the solar panel is connected with a terminal, and the terminal is electrically connected to a wiring terminal by a wire. The solar panel converts solar energy into electrical energy and stores it through the battery pack.

[0008] As a further solution of the utility model: a clamping plate is welded on the side of the box body, and the wire duct is adaptively clamped with the clamping plate, which can improve the installation stability of the wire duct.

[0009] As a further solution of the utility model: a groove is opened at the bottom of the temperature acquisition probe, and a temperature data acquisition module is installed inside the groove. The height of the temperature data acquisition module is less than the depth of the groove, and the groove can protect the temperature data acquisition module.

[0010] As a further solution of the utility model: a connecting wing is integrally formed on the side of the temperature acquisition probe, and a connecting hole is opened through the top surface of the connecting wing. A screw adapted to the connecting hole can fix the connecting wing.

[0011] As a further solution of the utility model: the alarm component is an alarm indicator light or an alarm buzzer or a combination of both, which can give an early warning when the equipment has a locking failure or a short-circuit failure.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. By setting a temperature sensor and a sound sensor capable of collecting the pitch, loudness and temperature information at the equipment failure point, the utility model can, when the equipment fails, detect the high temperature generated by the locking at the failure end by comparing the temperature at the failure point with the preset standard temperature. By combining the detection of the pitch and loudness of the sound at the failure part by the sound sensor, the source of the failure can be quickly judged, which is convenient for improving the maintenance efficiency.

[0014] 2. In the present utility model, a controller is connected by a bracket inside the first cavity. The bracket can isolate the controller from the bottom of the box body, reducing the influence of the temperature at the equipment failure point on the controller, avoiding excessive heat transfer from the failure point to the controller, thereby reducing the influence of the high temperature at the equipment failure point on the controller. By setting solar power to supply power to the controller, on the one hand, it can improve the convenience of using the warning device, and at the same time is conducive to energy conservation.
