Problems solved by technology
But ordinary dew point monitors place the sensor directly in the air, and add a dust cover outside the sensor to prevent dust from entering the sensor, so as to avoid inaccurate test results
But this will bring two problems: one is that if the air flow outside the sensor is not large, the response sensitivity of the sensor will be low; the other is that if the hole of the dust cover is blocked by dust, the air cannot flow in, and the test results will not allow

Embodiment Construction
[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening ele...

The invention discloses an intelligent dew point monitor and a monitoring method thereof.The intelligent dew point monitor is characterized by comprising a dew point sensor, a filtering device, an air convection device and a monitoring control device, the head of the dew point sensor is provided with the air convection device, and the front end of the air convection device is connected with the filtering device through a first air pipe; the side edge of the air convection device is connected to an air pipe connector of an air inlet of the monitoring control device through a second air pipe, and the dew point sensor is connected to a dew point sensor connector of the monitoring control device through a connecting line. The monitoring control device is used for detecting the dew point value of air sucked into the dew point sensor and the air flow flowing into the monitoring control device. According to the invention, the filter device and the air suction of the air pump are arranged, so that clean air passing through the vicinity of the sensor sensing chip flows, and then the air can uniformly flow through the position of the sensor sensing chip by combining the flow monitoring of the flow sensor with the control of the speed of the pump, so that the test sensitivity and precision can be guaranteed.
Description
technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to an intelligent dew point monitor and a monitoring method thereof. Background technique [0002] At present, some production workshops and places of use that have requirements for dew point, such as battery production workshops, use dew point monitors to monitor the dew point of the production environment in real time and find problems in time. But ordinary dew point monitors place the sensor directly in the air, and add a dust cover outside the sensor to prevent dust from entering the sensor, so as to avoid inaccurate test results. But this will bring two problems: one is that if the air flow outside the sensor is not large, the response sensitivity of the sensor will be low; the other is that if the hole of the dust cover is blocked by dust, the air cannot flow in, and the test results will not allow. For this reason, it is necessary to design a ne...
