[0002] Temperature is one of the important controlled variables in process control systems. Non-contact temperature measurement is usually used in industrial sites. Among the existing temperature and humidity data acquisition devices, the thermal resistance principle method is one of the most mature methods. Its temperature measurement principle is based on the property that the resistance value of a conductor or semiconductor changes with temperature, and the change in resistance value is reflected by a display instrument to achieve the purpose of temperature measurement.

[0004] During the collection process, existing temperature and humidity data collection equipment usually has a channel for air to flow into the equipment and contact the sensing resistor structure. However, as the collection equipment is used outdoors for a long time, dust and small garbage in the external environment are easily blown to the outside of the equipment by the airflow, or attached to the surface of the channel, causing blockage of the channel, affecting the normal circulation of air, and further affecting the collection and detection operations of the equipment.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] Example: Reference Figure 1 , Figure 2 A temperature and humidity data acquisition device shown in the figure includes a collector 1 and a panel 11 arranged on the front surface of the collector 1. A pair of air channels 12 are arranged on the surface of the panel 11. Air can enter the collector 1 through the air channels 12. The outer sides of the air channels 12 are arranged with inclined protective plates 21. An angle structure is formed between the protective plates 21 and the air channels 12. A plurality of intercepting plates 22 are arranged on the side of the protective plates 21 close to the air channels 12. The plurality of intercepting plates 22 are distributed in a stepped manner along the surface of the protective plates 21. The intercepting plate 22 closest to the air channel 12 is located at the highest position of the stepped structure.
[0022] During the actual operation of the temperature and humidity data acquisition device, the interception plates 22 arranged in a stepped manner can successively intercept impurities and garbage blown from the external environment to the front side of the air channel 12. Under the step-by-step interception of the interception plates 22, the impurities and garbage can be prevented from directly adhering to the surface of the air channel 12, reducing the contact of the impurities and garbage with the air channel 12, and still leaving space for air to pass through the air channel 12 and enter the interior of the collector 1. Under the premise of not affecting the efficiency of temperature and humidity data acquisition, the pollution of the air channel 12 by the external environment is reduced, which has a good protective effect and reduces the frequency of cleaning by the staff.
[0023] like Figure 1 , Figure 2 As shown, a plurality of guide blocks 3 are arranged on one side of the guard plate 21 close to the air passage 12 , and the plurality of guide blocks 3 are respectively located inside the spacing spaces formed by the plurality of intercepting plates 22 and the guard plate 21 , and extension rods 4 are fixedly connected to the surfaces of the plurality of guide blocks 3 .
[0024] The surface of the guard plate 21 is provided with a plurality of accommodating channels 23 for accommodating the extension rods 4 to slide up and down. The plurality of extension rods 4 on the same side in front of the collector 1 pass through one end of the accommodating channels 23 and are connected by a common handle 5 .
[0025] The control handle 5 is raised and lowered, and the multiple extension rods 4 and the guide block 3 located on the same side in front of the collector 1 are raised and lowered synchronously. The guide block 3 can quickly clean the impurities inside the interval space formed by the multiple interception plates 22 and the guard plate 21, reduce the adhesion of impurities inside the interval space, and achieve a quick cleaning effect.
[0026] like Figure 2 As shown, the upper and lower ends of a pair of guard plates 21 symmetrically distributed in front of the collector 1 are fixed by the horizontal plate 2, the horizontal plate 2 and the guard plates 21 are both against the surface of the panel 11, the left and right ends of the horizontal plate 2 are protruded outward to form alignment protrusions 24, and the four corners of the collector 1 are fixedly connected with positioning rods 14 that can penetrate the alignment protrusions 24. In the process of installing the horizontal plate 2 and the guard plates 21, the alignment protrusions 24 can be sleeved on the surface of the positioning rods 14 to achieve the effect of positioning the horizontal plate 2 and the guard plates 21.
[0027] like Figure 2 , Figure 3 As shown, the front end of the positioning rod 14 is provided with a rotatable stopper 15, and the surface of the alignment protrusion 24 is provided with a notch 241 for accommodating the stopper 15 to pass through. During the installation of the cross plate 2 and the guard plate 21, the alignment protrusion 24 on the cross plate 2 can be smoothly sleeved on the designated position on the positioning rod 14. When the cross plate 2 and the guard plate 21 abut against the surface of the panel 11, the stopper 15 rotates to the opposite direction of the notch 241 and abuts against the surface of the alignment protrusion 24, so as to achieve the purpose of locking the alignment protrusion 24, and prevent the cross plate 2 and the guard plate 21 connected thereto from being offset or falling off.
[0028] like Figure 1 , Figure 2 As shown, a detachable back plate 13 is installed on the back of the collector 1, and positioning holes are opened on the upper and lower positions of the back plate 13. The back plate 13 can be installed on various building surfaces through the opening of the positioning holes to achieve the purpose of stably installing the temperature and humidity data collection equipment.
