Description

Technical Field

[0001] The utility model relates to a wireless temperature measuring device for monitoring the surface temperature of mechanical equipment, and belongs to the technical field of temperature state monitoring of mechanical equipment. Background Technique

[0002] The common surface temperature monitoring schemes for mechanical equipment in the market mainly include two types: contact type and non-contact type. Contact temperature measurement is achieved by directly installing a temperature sensor on the surface of the object to be measured, usually using sensors such as thermocouples and thermal resistors. Non-contact temperature measurement utilizes the principle of infrared radiation. An infrared temperature sensor receives the infrared radiation energy emitted by the surface of the object to be measured, and then calculates the temperature.

[0003] Currently, most common non-contact infrared temperature sensors are in wired form and communicate data through an RS485 interface. Such sensors usually need to be fixedly installed at a specific position for continuous monitoring of the surface temperature of mechanical equipment. Installing the equipment requires laying RS485 communication cables, increasing the installation cost and complexity; once the sensor is installed, it is troublesome to adjust the position or replace it, and the maintenance difficulty is high; if additional monitoring points need to be added, additional wiring and communication configuration adjustment are required, and the system expansion cost is relatively high.

[0004] In addition, a handheld temperature gun can also be used for detecting the surface temperature of mechanical equipment, but the measurement depends on the manual operation of the operator, which is prone to human error and is not suitable for situations that require long-term continuous monitoring. For example, Chinese Patent Publication No. "CN221280455U" discloses a handheld laser temperature gun, which includes a gun barrel. A lens barrel is arranged in the gun barrel. The front end of the lens barrel extends to the nozzle of the gun barrel. The rear end of the lens barrel is connected with a temperature sensor. A fixing frame fixedly connected to the lens barrel is arranged at the nozzle of the gun barrel. A plurality of mounting grooves are formed in the fixing frame, and a laser lamp sight is arranged in each mounting groove. The emission direction of the laser lamp sight is the same as the outlet orientation of the lens barrel. By arranging a plurality of laser lamp sights with the same emission direction as the outlet orientation of the lens barrel, when the opening of the lens barrel is aligned with the temperature measurement area and assisted by a plurality of laser lamp sights, the central area can be quickly found, thereby improving the temperature measurement speed and accuracy. For large-scale or frequent temperature monitoring tasks, the cost-effectiveness of using a handheld temperature gun alone is relatively low. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a wireless temperature measuring device for monitoring the surface temperature of mechanical equipment. By adopting non-contact infrared temperature measurement and wireless communication technologies, a flexible and convenient temperature monitoring scheme is realized, the equipment management efficiency is improved, the maintenance cost is reduced, and the safety is enhanced.

The external button antenna and the sensor main body are connected through an SMA interface. The mounting base adopts a ring magnetic adsorption mounting structure, and the infrared temperature measuring probe of the sensor main body is installed in the ring structure of the mounting base.

[0008] By adopting non-contact infrared temperature measurement and wireless communication technologies, a flexible and convenient temperature monitoring solution is realized, which helps to improve equipment management efficiency, reduce maintenance costs and improve safety. Through the ring magnetic adsorption mounting structure, it is not necessary to hold by hand, which is convenient for quick deployment and movement.
