Description

The invention relates to the technical field of temperature measuring equipment, in particular to a temperature measuring device which is used by industrial field equipment and can automatically position a temperature measuring point.
Background
In industrial sites, monitoring the temperature of production equipment enables the operating state of the equipment to be assessed. For example, in the current secondary water supply pump house, generally the staff measures through hand-held type thermoscope when patrolling and examining, because the artificial mode can not realize lasting long-time operating temperature monitoring, when the motor takes place because lack of phase or short circuit etc. the motor temperature can rise fast, it is improper to have gas or control parameter in the pump body of water pump, the water pump can form the pungency and beat, water lasts at the pump inner loop, the pump body generates heat, can reach 100 degrees at most, the rubber circle above the mechanical seal that can lead to the water pump is ageing like this, the water pump leaks, life reduces. In addition, if the variable frequency driving control system of the secondary water supply equipment is in heavy load operation for a long time, the temperature rises quickly, the structure is deformed, and the electrical service life is reduced. In conclusion, it is very necessary to monitor the temperature of key components and parts such as a water pump, a frequency converter, a contactor, a pipeline, a cabinet body and the like, and the service life of equipment is prolonged and the fire risk is reduced by early warning and alarming the operation of facility equipment through the heating phenomenon.
In the field of existing industrial production, when a lot of heating devices and components need to monitor temperature in one area, a set of infrared temperature detectors (not applied in a secondary water supply system) with data output ports based on pan-tilt control is generally installed, and the infrared temperature detectors are installed in the middle of each device needing to be monitored; when the intelligent internet equipment works, the motor reducing mechanism (the holder comprises two sets of motor reducing mechanisms and an industrial personal computer which can drive the infrared temperature detector to move in the horizontal and vertical directions) drives the infrared temperature detector to move in the horizontal and pitching modes, the front end detection head of the intelligent internet equipment detects the temperature of a plurality of pieces of equipment needing temperature detection in sequence, and then data are transmitted to the intelligent internet equipment (a mobile phone or a PC) of remote related personnel in a remote mode through a network cable or a GPRS module wireless mode. Although the existing infrared temperature detector can realize reciprocating rotation and pitching motion of nearly 360 degrees and sequentially detect the temperature of each device, the existing infrared temperature detector is limited by the structure, the temperature measuring point is positioned manually, the efficiency is low, the deviation is large, the repeated positioning precision is low, the key temperature measuring point is difficult to keep, especially the local temperature measurement on an electrical element, meanwhile, the existing infrared temperature detector rotates a certain angle every level or pitching under the action of a motor reducing mechanism, then the control program for measuring the temperature of the corresponding device after stopping the movement for a period of time comes from a main control circuit board fixed program in an industrial personal computer, the control program is influenced by the fluctuation of input voltage and the deterioration of the performance (such as gear abrasion and slippage and the like) of the motor reducing mechanism, a certain angle and position deviation can occur after each stop of the movement, the accumulated deviation is larger, namely the time is long, each time the main control circuit controls the motor reducing mechanism to stop working, the infrared temperature detector may not be aligned with the device needing temperature detection or deviate from the heat source point of the device, so that the detected temperature data cannot truly reflect the temperature data of the corresponding device. In addition, after the existing infrared temperature detector is used for a period of time, because a front-end detection head of the existing infrared temperature detector has no cleaning equipment, the detection head is possibly affected by adhesion of dust and the like, and when workers do not clean the detection head in time, deviation of detected temperature data can be caused. In summary, it is necessary to provide an infrared temperature measurement system capable of effectively ensuring the cleanliness of a probe of an infrared temperature detector and effectively detecting temperature data of each device.

The regulated power supply A1 is a finished product of a 220V/12V/500W AC-to-DC 12V switching power supply module. The control circuit comprises a time control switch A3 and a relay K1 which are connected through circuit board wiring, wherein two ends 1 and 2 of the power input end of the time control switch A3 are respectively connected with the positive pole and negative pole control power input end of the relay K1, and the power output ends 3 and 4 of the time control switch A3 are respectively connected with the two power input ends of the relay K1.
As shown in fig. 1, 2 and 3, power input terminals 1 and 2 of a regulated power supply a1 and two poles of an alternating current 220V power supply are respectively connected through a lead, power output terminals 3 and 4 of a regulated power supply a1 and two power input ends of a main control circuit board a2 of an industrial personal computer, two power input ends of a camera SX, two power input ends of an infrared temperature detector CW, two power input ends of a control circuit time control switch A3 and two power input ends of a WiFi data receiving module a6 are respectively connected through leads, two normally closed contact ends of a control circuit time control switch A3 and a relay K1 and positive and negative and positive pole power input ends of an electric push rod M1 are respectively connected through leads; the signal output end of the WiFi data receiving module A6 is connected with the third signal input end of the main control circuit board A2 through a data line.
As shown in fig. 1, 2 and 3, after a 220V ac power supply enters a power input end of a regulated power supply a1, pins 3 and 4 of a power output end of a regulated power supply a1 output a stable dc 12V power to enter power input ends of an industrial personal computer, a camera SX, an infrared temperature detector CW and control circuit, and a WiFi data receiving module a6, so that the industrial personal computer, the camera SX, the infrared temperature detector CW and control circuit, and the WiFi data receiving module a6 are powered on to operate. The CW temperature measuring mode of the infrared temperature detector is completely consistent with that of the existing equipment, the power output end of the main control circuit board A2 of the pan-tilt industrial personal computer outputs positive and negative and positive bipolar power supplies at intervals of a certain time to control the working mode of two sets of motor reducing mechanisms M, and then the power output shafts of the two sets of motor reducing mechanisms M respectively drive the CW rotation of the infrared temperature detector to approach 360 degrees clockwise or anticlockwise rotation (for example, the CW rotation measures the temperature once every 20 minutes or continuously measures the temperature circularly), and the CW rotation rotates a certain angle in the vertical direction to measure the temperature of the relevant equipment. In the clockwise rotation process of the infrared temperature detector CW, a detection head of the infrared temperature detector CW can sequentially pass through the front ends of devices needing temperature measurement to sequentially measure the temperature of a plurality of devices, the detected temperature data is output to a main control circuit board A2 through a signal output end of the infrared temperature detector CW, the main control circuit board A2 remotely transmits the data in a wired or wireless mode under the action of an internal circuit and an application unit thereof, remote related personnel can effectively master the temperature data of each device on site after receiving the temperature data through the application unit in a smart phone or a PC and the like, and can modify strategies to control temperature measurement time intervals of different temperature measurement points, so that key and important parts are monitored in a key mode, and non-key parts reduce the measurement frequency; after rotating counterclockwise by nearly 360 degrees, the infrared temperature detector CW returns to the initial position to prepare for the next temperature measurement. A special correction target is arranged at a certain fixed position, and accumulated errors generated in the motion process of the tripod head are corrected through a camera at intervals (such as one month), so that a continuous and stable position error range is ensured.
As shown in fig. 1, 2, and 3, after the control circuit is powered on, the time switch a3 will output power for a certain time at intervals under the action of the internal circuit and the power output time of 3 and 4 pins set by the technician, and then the power will enter the positive and negative pole power input ends of the electric push rod M and the power input ends of the relay K1 (for example, the power will be output for 20 seconds at intervals of 72 hours), so that the piston rod of the electric push rod M after the positive and negative poles are powered on can drive the cleaning head 41 to move once from bottom to top, and the rear end of the cleaning head 41 automatically cleans the detecting head of the infrared temperature detector CW and the front end of the camera SX (the piston rod of the electric push rod does not work after moving to the top dead center), thereby ensuring the image pickup effect of the camera SX and the subsequent temperature measurement effect of the infrared temperature detector CW on the device. In the power-off time of the relay K1, two control power input ends and two normally closed contact ends of the relay are respectively closed, so that the power input ends of the negative pole and the positive pole of the electric telescopic rod M are powered on, and then a piston rod of the electric push rod M can drive the cleaning head 41 to move from top to bottom once to return to an initial position (simultaneously, the detection head and the camera of the camera are cleaned once again) to prepare for next cleaning (the cleaning head 41 is positioned at the lower ends of the detection head and the camera).
As shown in fig. 1, 2 and 3, each time the motor reducing mechanism clockwise drives the infrared temperature detector CW and the camera SX to rotate, the camera SX can make a real-time image of the target picture information of the front end (temperature measuring point) of the temperature measuring device and output the image to the data collecting unit, the data collecting unit can collect the corresponding target picture image data shot by the camera and output the data to the data judging unit when working, the data judging unit compares the data according to the input target picture data and the data of the photosensitive plate model (target) stored in the data collecting unit, when the data are matched (i.e. after being matched with the target data stored in the data collecting unit), an instruction signal is output to the control unit, the control unit controls the two sets of motor reducing mechanisms to stop working within a certain time, then the action unit controls the working modes of the two sets of motor reducing mechanisms to drive the infrared temperature detector CW to rotate back and forth at a certain angle in the horizontal direction (X axis), and the infrared temperature measuring beam emitted by the infrared temperature detector is aligned with the light sensing plate of the infrared receiving target module A4 at the corresponding equipment. Infrared light strikes a photosensitive plate of the infrared receiving target module A4 to indicate that a temperature measuring point is centered, a data judging unit of the control system records the current positions of a horizontal shaft and a vertical shaft, after receiving an infrared signal, the infrared receiving target module A4 outputs a voltage signal to a signal input end of a Wifi transmitting module A5 under the action of an internal circuit, then the Wifi transmitting module A5 transmits a wireless instruction signal, the Wifi receiving module A6 outputs a signal to the control unit after receiving an instruction, and the control unit controls two sets of motor speed reducing mechanisms to stop moving through an action unit, so that the infrared temperature CW detector can effectively measure the temperature of a heating surface of equipment (the temperature measuring error is less than 1 cm); after a certain time interval (generally 3 seconds), the control unit controls the two sets of motor reducing mechanisms to drive the infrared temperature detector to rotate by a certain angle again to measure the temperature of the next target temperature measuring point. After the temperature measurement is finished, the control unit controls the two sets of motor reducing mechanisms to drive the infrared temperature detector to rotate anticlockwise for 360 degrees, and then the infrared temperature detector CW returns to the initial position to prepare for the next temperature measurement. In the invention, for the convenience of identification, the arranged curtain can form a contrast light spot emitted by a standard infrared temperature detector CW, so that the comparison precision and efficiency are improved, the operation of the contrast light spot is repeated, the temperature measurement and positioning of the visual range of each key component can be completed, thus the target can be automatically identified and tracked based on artificial intelligence, wherein the center of the target (similar to a target shooting 10 rings) is a temperature measuring point.
