Problems solved by technology
[0005] The purpose of the present invention is to provide a digital passive wireless sensor, which mainly solves the problem that when the wire is suspended, the abnormal situation at the connection between the wire and the wire is not easy to be detected. It will cause the temperature at the joint to rise rapidly, and it will easily fuse the wire or even catch fire, causing harm to personal and property safety. Most of the existing traditional sensors use optical fiber to measure the temperature of the wire joint, which increases the distance. The problem of resource burden for distance transmission

The invention relates to the technical field of sensors, in particular to a digital passive wireless sensor which comprises a sensor body, a second through hole is formed in the middle of the sensor body in the vertical direction and located at the upper end of the first through hole, and the inner wall of the second through hole is in threaded connection with a first lead screw. A rotating head is fixedly connected to the upper end of the first screw rod, a first groove is formed in the lower end of the first screw rod, a signal transmitter is fixedly connected to the inner wall of the first groove, a thermocouple is fixedly connected to the lower surface of the signal transmitter, and a signal receiver is fixedly connected to the upper surface of the sensor body; a solar power generation panel is fixedly connected to the upper surface of the sensor body and located on the right side of the signal receiver, and the problem that the resource burden of long-distance transmission is increased due to the fact that temperature measurement of a wire connector is mostly conducted through optical fibers by means of an existing traditional sensor is solved.
Description
technical field [0001] The invention relates to the technical field of sensors, in particular to a digital passive wireless sensor. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. [0003] At present, when the wires are suspended, the abnormality of the connection between the wires and the wires is not easy to be detected. If the wires have too much current or poor contact at the joints, the temperature at the joints will rise rapidly, which will easily fuse the wires or even cause a fire. , causing harm to personal and property safety, most of the existing traditional sensors for temperature measurement of wire joints are transmitted by optical fibers, which increases...
