Based on the above, it is especially necessary to provide a sensor based on magnetic steel as a probe, which can be conveniently adjusted and can remotely adjust and control temperature.

As shown in fig. 1 and 2, when the remote controller is used, after the power switch S is turned on, the gear power switch SK and the remote controller U1 are in an electric working state. In the application of the invention, when the lower end of the magnetic steel 5 is in close contact with a monitored point (namely a heating point of monitored equipment, the cylinder 7 can effectively transfer heat, and actually the lower end of the magnetic steel 5 is in contact with the inner lower end of the cylinder 7), the magnetic steel 5 keeps magnetism at a relatively lowest monitoring temperature (for example, below 103 ℃), and the internal contact of the reed switch GH is closed or opened under the action of magnetic force, so that the opening or closing of related electric equipment is automatically controlled. When a user drives the magnetic steel 5 to move upwards or downwards through the gear power switch SK or the remote control circuit U1 through the motor speed reducing mechanism M, the lower end of the magnetic steel 5 and the monitored point are changed in height, and therefore the heat radiated by the monitored point at the lower end of the magnetic steel can be changed synchronously.

When the magnetic steel 7 needs to be remotely controlled to go down, an operator operates a mobile phone interface to send a first path of wireless closing instruction, a wireless mobile network transmits an instruction signal in real time, and after a remote wireless controller finished product U1 with a far end positioned at the magnetic steel receives the first path of closing control signal, a first path of control power supply output end 3 pin of a remote wireless controller finished product U1 outputs a power supply to enter a relay K positive power supply input end, so that the relay K is electrified to attract two control contact ends of the relay K to be respectively communicated with two normally open contact ends; because, two control contact ends of relay K and the two poles of the earth of battery G communicate with each other respectively this moment, and two normally open contact ends of relay K are connected with the positive and negative two-pole power input end of motor reduction gears M, so, motor reduction gears M can be worked its power output shaft by electrician and drive internal thread pipe 91 anticlockwise rotation this moment, and the internal thread of internal thread pipe 91 acts on the external screw thread of trace 52, and then, trace 52 drives magnet steel 5 and descends. When the magnetic steel 7 needs to be remotely controlled to ascend, an operator operates a mobile phone interface to send a second wireless closing instruction, and after a remote wireless controller finished product U1 receives a second closing control signal, a second control power supply output end pin 3 of a remote wireless controller finished product U1 outputs power to enter an anode power supply input end of the relay K1, so that the relay K1 is electrified to attract two control contact ends of the relay K1 to be respectively communicated with two normally open contact ends; because two control contact ends of the relay K1 and two poles of the battery G are respectively communicated at the moment, and two normally open contact ends of the relay K1 are connected with the negative and positive pole power input ends of the motor reducing mechanism M, at the moment, the motor reducing mechanism M can work by an electric operator to enable the power output shaft of the motor reducing mechanism M to drive the internal threaded pipe 91 to rotate clockwise, the internal thread of the internal threaded pipe 91 acts on the external thread of the linkage rod 52, and then the linkage rod 52 drives the magnetic steel 5 to move upwards. During remote control, a manufacturer gives appropriate time for sending instructions by the mobile phone according to actual production, for example, after the mobile phone sends the instructions for 2 seconds in all, the magnetic steel can move up and down by 5mm, and then an end user can control the instruction time according to the requirement. For example, the magnetic steel needs to go up and down 2.5mm, a 1-second wireless signal instruction is sent by the mobile phone, and after the mobile phone sends the 1-second instruction, the instruction signal is quickly turned off (the mobile phone software has an option of sending instruction time, for example, 2 seconds after clicking the interface, the finished remote wireless controller product U1 automatically outputs a 2-second instruction signal, and the output is stopped after 2 seconds), so that the power supply output of 3 or 4 pins of the finished remote wireless controller product U1 is stopped. According to the invention, an operator can realize the adjustment of the distance between the magnetic steel probe and the monitored object through simple operation, and can remotely control the adjustment of the distance between the magnetic steel probe and the monitored point through a mobile phone, so that the closing or opening control of the power switch contacts on or off different temperatures of the monitored object is realized, and the advantage of wider application range (adjustable monitoring temperature) is achieved.
