Detector device for frequency detection quality

Abstract

The invention discloses a detector device for frequency detection quality, which comprises a control case and a connector, wherein a touch display screen is fixedly installed on the outer surface of the control case; a starting button is arranged below the touch display screen; an input key is arranged on one side of the starting button; a work indicating lamp is arranged on the other side of thestarting button; a connecting rod is arranged on one side of the control case; and a voice device is arranged on the other side of the control case. According to the detector device for frequency detection quality, as an anti-scratching protective layer, an infrared counting instrument and the voice device are arranged, the touch display screen can be prevented from generating scratches on the surface after being used for a long time, the definition of the touch display screen is protected, voice prompt can be conducted when a worker operates the machine, the familiarity of people on the operation process of the machine is accelerated, the device is suitable for different working conditions, and better using prospects are brought.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a detection machine device for frequency detection quality. Background technique [0002] The frequency measuring instrument is an electronic measuring instrument specially used to measure the frequency of the signal under test. The frequency measuring instrument is mainly composed of four parts: time base circuit, input circuit, counting display circuit and control circuit. During a measurement cycle, the measured periodic signal is amplified, shaped and differentiated in the input circuit to form a narrow pulse of a specific period, which is sent to an input terminal of the main gate. The other input terminal of the main gate is the gate pulse generated by the time base circuit. When the gate pulse opens the main gate, the narrow pulse of a specific period can pass through the main gate and enter the measuring instrument for counting. The display circuit of the measuring in...

Problems solved by technology

[0003] There are certain disadvantages in the use of existing frequency detector devices. First, after a long-term use of the touch screen, the surface is prone to scratches, which affects the clarity of the touch screen and is not convenient for people to view data. Secondly, the operation It is more troublesome, it is difficult for novices to get started, and the function is relatively single. It can only perform frequency detection and cannot adapt to people's higher production needs, which has brought a certain impact on people's use process. Therefore, we propose a method for Detecting machine device for frequency detection quality
