Embodiment Construction
[0042] The following examples refer to figure 1 .
[0043] device embodiment.
[0044] The present invention relates to an on-line testing device for the surface temperature of a rotating barrel of a small-caliber revolving cannon, which includes a data acquisition system and an installation adjustment frame, and also includes an online infrared detector, a high temperature resistant cable, a separate electronic converter and an on-site infrared calibrator. The online infrared detector is installed on the installation adjustment frame so that the detection distance D between the detection surface and the measured point is 5m. The output end of the online infrared detector is connected to the input end of the separate electronic converter through a high temperature resistant cable. The output terminal of the separated electronic converter is connected to the input terminal of the data acquisition system. During on-site calibration, the detection surface of the online infrared ...

The invention discloses an online testing device and method for the surface temperature of a rotary barrel of a small-caliber rotary cannon, which is used to solve the technical problem of poor practicability of the existing temperature testing device. The technical solution is that the device includes a data acquisition system, an installation adjustment frame, an online infrared detector, a high temperature resistant cable, a separate electronic converter and an on-site infrared calibrator. The online infrared detector is used for non-contact extraction of the temperature signal of the barrel surface; the high temperature resistant cable is used for the temperature signal transmission at an ambient temperature of 250°C; the separated electronic converter, through the intelligent operation panel with buttons and backlit LCD display, Realize parameter setting and remote monitoring of target emissivity, lower limit temperature, upper limit temperature, response time, output voltage, etc.; the on-site infrared calibrator is used for online temperature calibration of a complete set of test devices. The device can realize the temperature parameter test of the rotating barrel surface in the whole process before, during and after launching, and has good practicability.
Description
technical field [0001] The invention relates to an online testing device for the surface temperature of a rotating barrel of a small-caliber rotary gun, and also relates to an online testing method for the surface temperature of the rotating barrel of a small-caliber rotary gun. Background technique [0002] When the small-caliber rotary gun is fired, the temperature of the outer surface of the rotating barrel should not exceed 400°C, otherwise the firing performance will be affected. Since the measured multiple barrels are rotating at high speed around the same axis, and the effective detection area of the circular outer surface of each measured barrel is very small, the temperature measurement equipment is required: First, non-contact temperature measurement method should be used , The second is that the minimum detectable area should be small enough, the third is that the response time should be short, the fourth is that the temperature measurement range is relatively l...
