The invention aims to provide an outdoor icing detection sensor which is used for rapidly detecting whether icing is formed on the surfaces of building facilities and the like.
Specifically, the sensor comprises a heatable coupling electrode type sensor and a non-heatable coupling electrode type sensor which respectively measure the coupling current of the surfaces of the sensors.
The device comprises a heatable coupling electrode type sensor, a first temperature sensor and a heating resistance wire, wherein the first temperature sensor and the heating resistance wire are arranged on the heatable coupling electrode type sensor, and the temperature of the first temperature sensor and the heating resistance wire is controlled to be 0-4 ℃ so that the surface of the first temperature sensor and the surface of the heating resistance wire are not frozen.
Specifically, the air temperature measuring device further comprises a second temperature sensor arranged on the unheated coupling electrode type sensor, and the second temperature sensor is used for measuring the air temperature.
Specifically, the adjacent parts of the coupling electrode type sensor which can be heated and can not be heated adopt a heat insulation layer or a hollow design, so that heat conduction during heating is prevented.
Specifically, the heatable coupling electrode type sensor, the unheated coupling electrode type sensor, the temperature sensor and the heating resistance wire are all connected to the control circuit board.
Specifically, the control circuit board processes sensor data and controls the heating power of the heating resistance wires, and uploads the data to the detection monitoring equipment.
Specifically, the control circuit board and the sensor are both fixed on the shell.
Specifically, the casing is split type structure, the sensor all protrudes surface mounting, the casing has the cable through-hole.
Specifically, the heatable coupling electrode type sensor (and the unheated coupling electrode type sensor have a measuring part structure that a plurality of metal sheets are alternately arranged and combined, the metal sheets are pairwise paired and are composed of two different metal materials, the principle that two different metals are coupled to generate electromotive force is utilized, one of the metal sheets is used as a working electrode, the other metal sheet is used as an auxiliary electrode, the middle of the auxiliary electrode is separated by an insulating sheet, and the coupling current of electrolyte on the surface of the auxiliary electrode is measured.
Based on the above structural scheme, the detection method and principle of the invention are as follows.
In particular, the sensor should be installed outdoors, adjacent to the facility to be detected or embedded in the detection facility.
Further, when the environment where the sensor is located is higher than 0 ℃, only the temperature sensor works inside the ice-coating sensor, and the coupling electrode type sensor is in a standby state.
Further, when the ambient temperature is reduced to 0 ℃, the sensor is automatically started, and the heating resistance wire of the heatable coupling electrode type sensor starts to heat, so that the surface temperature of the heating resistance wire is higher than 0 ℃.
Further, when the detection environment is lower than 0 ℃ and ice is formed, the temperature of the heatable coupling electrode type sensor is controlled to be in a state that the ice on the surface is water at 0-4 ℃, and the control circuit board receives the coupling current data of the heatable coupling electrode type sensor with the surface being water.
Further, under the same condition as the above step, the surface of the unheated coupling electrode sensor starts to be coated with ice, and at this time, the control circuit board receives coupling current data of the surface of the unheated coupling electrode sensor coated with ice.
Further, the control circuit board judges whether the ice coating is formed on the surface of the sensor through calculating the environmental sensor data and the coupling electrode type sensor data.
Further, once the ice coating is formed, the control circuit board sends an ice coating signal to the monitoring system.
Compared with the existing icing detection technology, the invention has the following advantages:
1. dealing with more complex outdoor environments. Because the outdoor environment changes at any time, the single detection icing formation is easy to be interfered, the dual-coupling electrode type sensor can self-control the temperature, carry out bidirectional contrast detection and eliminate interference options;
2. an icing signal can be sent out at the initial stage of icing formation. Most of the icing detection sensors can only react when the icing is formed to a certain degree at the present stage, and the icing detection method can detect the icing at the initial stage of the icing formation;
3. the use of the anti-corrosion and anti-aging material ensures the stability and durability of use.
