Embodiment Construction

[0013] The present invention is further described in conjunction with the following examples.

[0014] Such as figure 1 As shown, a hydrogen sulfide online detection device includes a microprocessor 1 , a data acquisition device 3 connected to the microprocessor 1 , a data display device 2 , a user terminal 5 and a hydrogen sulfide gas sensor 4 . The data acquisition device 3 collects the detected gas in the ambient gas and then transmits it to the hydrogen sulfide gas sensor 4. The hydrogen sulfide gas sensor 4 generates a detection signal in the measured gas environment, and the detection signal is displayed on the data display after being processed by the microprocessor 1. The screen of device 2. The microprocessor 1 is a Rabbit Semiconductor 20-668-0011 processor. In other embodiments, an 8086 microprocessor can also be used.

[0015] In this embodiment, the hydrogen sulfide gas sensor is a resistance-controlled gas sensor, using doped SnO 2 Gas sensitive thin film as ...

Abstract

The invention discloses a hydrogen sulfide on-line detection device. The detection device comprises a microprocessor, and a data acquisition device, a data display device, a user terminal and a hydrogen sulfide gas sensor which are connected with the microprocessor. The data acquisition device, the data display device, the user terminal and the hydrogen sulfide gas sensor are connected with the microprocessor to form the on-line detection device for the hydrogen sulfide gas, so that the on-line detection device system structure can monitor whether the hydrogen sulfide gas content of the environment exceeds standard or not in real time, transmits the result to the user terminal through a digital display mode, is convenient for a user to check, and overcomes the defect that the hydrogen sulfide detection device in the related technology cannot perform monitoring in real time and continuously.

Description

technical field [0001] The invention relates to the field of environment, in particular to an online detection device for hydrogen sulfide. Background technique [0002] With the development of science and technology, the progress of industry and agriculture, and the improvement of human living standards, people are increasingly aware that the gas atmosphere in the surrounding environment has a major impact on their own production and life. Among them, the leakage or random discharge of toxic and harmful gases will not only directly endanger human health, but also cause serious pollution to the environment and destroy the ecological balance. [0003] However, humans themselves can detect a few odorous gases through the nose, but have no way of knowing their exact concentrations. Therefore, it is particularly important to develop sensor devices for gas detection. The gas sensor can sense a specific gas and convert its concentration into an output signal (generally an electr...
