The following describes a heat trace pipe temperature detection system, a method, a storage medium, and an electronic apparatus according to an embodiment of the present invention with reference to the accompanying drawings.
In one embodiment of the present invention, referring to fig. 1, there is provided a heat tracing pipe temperature detection system including: the heat tracing pipe 1, the positioning wire 2, the temperature sensor 3, the winding device 4 and the data processing device 5, wherein the positioning wire 2 passes through the inner side of the heat tracing pipe 1, and the temperature sensor 3 is fixed on the positioning wire 2; wherein,

A data processing device 5 for receiving temperature data of each location; based on the temperature data of each position, the position where the cold spot exists on the heat tracing pipe 1 is determined.
Wherein, the heat tracing pipe 1 can be a parallel heat tracing pipe, namely a heat tracing pipe with a plurality of electrothermal alloy wires; the heat tracing pipe may be a serial heat tracing pipe, that is, a heat tracing pipe with heat tracing by one alloy wire, which is not limited by the embodiment of the present invention.
The positioning wire 2 is made of a wire, for example, a plastic nylon rope.
The temperature sensor 3 may be a temperature sensor applying the metal expansion principle, a sensor that measures temperature based on the volume change of liquid and gas, or the like.
The winding device 4 may be an electric winding device or a manual winding device, which is not limited in the embodiment of the present invention.
One end of the positioning wire 2 can be fixed on the winding device 4 and then rotates around the winding device 4, so that the positioning wire 2 is wound around the winding device 4, winding is completed, and the reverse rotation is paying off.
In one embodiment of the present invention, the positioning wire 2 is shaped as a coil passing through the heat tracing pipe 1, and the total length of the coil is not less than three times the length of the heat tracing pipe 1.
As shown in fig. 1, the positioning wire 2 may form a coil, after passing through the heat tracing pipe 1, back to the winding device 4, and both ends of the positioning wire 2 are butted at the winding device 4. In this way, the wire winding device 4 rotates to simultaneously pay out and receive the wire, so that the coil rotates while passing through the heat tracing pipe 1, and the temperature sensor 3 fixed on the positioning wire 2 passes through the heat tracing pipe 1 along with the rotation process to measure the temperature of each position.
The coil is long enough to pass through the heat tracing pipe 1 and return to the winding device 4, so that the winding device 4 can simultaneously pay off and wind, and the wire extending from the other end of the heat tracing pipe 1 is recovered in the process of moving the temperature sensor 3.
The temperature data includes temperatures obtained by measuring the temperature of each location.
In addition, the positioning wire 2 may pass through the heat tracing pipe 1 in a straight line without forming a coil, and in this case, the wire winding device 4 may be provided at an end of the positioning wire 2 that passes out of the heat tracing pipe 1 and take up the wire, and pull the temperature sensor 3 to move in the heat tracing pipe 1.
The data processing device 5 may be implemented by any type of electronic equipment such as a personal computer, a server, a mobile terminal, etc., which is not limited in this embodiment of the present invention.
The position where the cold spot exists on the heat trace pipe 1 can be determined based on the temperature data of each position in the following manner.
And determining the temperature at each position through the temperature data record, determining whether an area with the temperature lower than a temperature threshold exists on the heat tracing pipe 1, if so, determining that a cold point exists, determining the position of the heat tracing pipe 1 corresponding to the temperature data with the temperature lower than the temperature threshold, and obtaining the position of the cold point.
Otherwise, the data processing device 5 is further configured to determine whether the temperatures indicated by the temperature data of each location are higher than a preset temperature threshold after receiving the temperature data of each location, and if so, determine that the heat tracing pipe 1 has no cold spot.
The temperature threshold may be set based on a pre-calculated temperature at which crystallization may occur.
The specific implementation of the location of the cold spot is described in the examples below and is not described in detail here.
In the scheme provided by the embodiment of the invention, by using the heat tracing pipe temperature detection system, the positioning wire 2 is controlled by the winding device 4, and then the temperature sensor 3 fixed on the positioning wire 2 is driven by the positioning wire 2 to move in the heat tracing pipe 1, so that the temperature of each position of the heat tracing pipe 1 can be conveniently measured at the inner side of the heat tracing pipe 1, and the process of controlling the movement of the temperature sensor 3 can be finished at the outer side of the heat tracing pipe 1 by the winding device 4, so that the operation is simple, and the convenience of the scheme provided by the embodiment of the invention is improved.
In addition, the obtained temperature data is directly input into the data processing device 5, and is processed by the data processing device 5 to determine the position of the cold spot, so that the temperature sensor 3 does not need to be manually taken out from the heat tracing pipe 1 to read the temperature, and the convenience of the scheme provided by the embodiment of the invention is further improved.
In the process of determining the position of the cold point in the process, the temperature data of each position inside the heat tracing pipe 1 can be obtained without disassembling the heat tracing pipe 1 or taking down the metal wire for cutting off, so that the position where the cold point exists is determined, the heat tracing pipe 1 is not damaged in the whole process, and the cost for detecting the temperature of the heat tracing pipe 1 is reduced.
In one embodiment of the present invention, the specific implementation manner of determining the location where the cold spot exists on the heat tracing pipe 1 by the data processing device 5 based on the temperature data of each location is as follows:
Determining first temperature data representing a cooling start point and second temperature data representing a cooling end point in a temperature data sequence formed by the temperature data of each position; in the temperature data sequence, the temperature represented by the temperature data between the first temperature data and the second temperature data is smaller than a preset temperature threshold value, and the temperature represented by the first temperature data and the temperature represented by the second temperature data are not smaller than the preset temperature threshold value; the position of the cold spot on the heat trace pipe 1 is determined based on the first temperature data and the second temperature data.
The temperature data at each position is arranged in the moving direction of the temperature sensor 3 in the heat tracing pipe 1, and a temperature data sequence can be obtained.
As shown in fig. 1, A, B denotes both ends of the heat trace pipe 1. Taking the example that the sensor enters the heat tracing pipe 1 from the A and leaves the heat tracing pipe 1 from the B, the temperature data of each position obtained by the sensor is arranged according to the sequence of the temperature data obtained by the temperature sensor 3, so that a temperature data sequence from the A end to the B end can be obtained.
The temperature data sequence shows the temperature change from the a-side to the B-side as shown in fig. 2.
As shown in fig. 2, the first temperature data and the second temperature data are temperature data represented by DSP and DEP, respectively. DSP is temperature data corresponding to a point on the curve before the temperature dip, and DEP is temperature data corresponding to a point on the curve after the temperature dip.
T+ - ΔT represents a preset temperature threshold. Wherein T represents an expected value of a preset temperature, and Δt represents a floating value.
Thus, a low temperature position as shown in fig. 2, that is, a position where a cold spot exists on the heat trace pipe 1 is detected between the first temperature data and the second temperature data.
In the case where the temperature sensor 3 cannot directly record the positional information, the temperature data series may exhibit a relative positional relationship of the respective temperature data, thereby indirectly obtaining the positional information and determining the position where the cold spot exists.
The following examples illustrate specific implementations of determining the location of the cold spot on the heat trace pipe 1.
In one embodiment of the present invention, determining a location on the heat trace pipe 1 where a cold spot exists based on the first temperature data and the second temperature data includes:
Determining the total amount of first temperature data between the third temperature data and the fourth temperature data in the temperature data sequence; the third temperature data and the fourth temperature data are temperature data of two end point positions of the heat tracing pipe 1; determining a second total amount of temperature data between the third temperature data and the first temperature data in the temperature data sequence, and determining a third total amount of temperature data between the third temperature data and the second temperature data;
And determining the position of the cold spot on the heat tracing pipe 1 based on the first proportion of the total amount of the second temperature data to the total amount of the first temperature data and the second proportion of the total amount of the third temperature data to the total amount of the first temperature data.
The third temperature data and the fourth temperature data may be determined based on the temperature change at both ends of the heat tracing pipe 1 indicated by the temperature data sequence. Since the outside environment is not provided at both ends of the heat tracing pipe 1, and the temperature is low relative to the inside of the heat tracing pipe 1, there is a sudden change in the temperature when the temperature sensor 3 enters and exits the heat tracing pipe 1, that is, the temperature represented by the temperature data reaches the temperature threshold or more when the temperature sensor 3 is at both ends of the heat tracing pipe 1.
The determining the location of the cold spot on the heat tracing pipe 1 based on the first ratio of the second temperature data total amount to the first temperature data total amount and the second ratio of the third temperature data total amount to the first temperature data total amount in the foregoing embodiment may be implemented as follows.
Determining the length of the heat tracing pipe 1 based on the first temperature data amount, the average speed of movement of the temperature sensor 3 in the heat tracing pipe 1, and the movement time of the temperature sensor 3 in the heat tracing pipe 1;
Determining a first position on the heat tracing pipe 1 according to the length of the heat tracing pipe 1 and the first proportion;
Determining a second position on the heat tracing pipe 1 according to the length of the heat tracing pipe 1 and the second proportion;
The location of the cold spot present is determined to be a location between the first location and the second location.
Taking fig. 2 as an example, SP and EP represent temperature data of the temperature sensor 3 entering and leaving the heat tracing pipe 1, respectively. At SP, EP there is a mutation in temperature and the temperature data represented by SP, EP are both greater than T.+ -. DeltaT.
The first temperature data total amount represents the number of temperature data between the first temperature data and the second temperature data in the temperature data sequence, that is, the number of positions where the temperature is measured. The longer the length between the first temperature data and the second temperature data, the more the number of the temperature data therebetween, and the larger the value of the total amount of the first temperature data.
Specifically, the temperature sensor 3 may be moved at a constant speed by controlling the winding device 4, and the temperature sensor 3 measures and obtains temperature data once every a fixed period of time, so that the total amount of the obtained first temperature data represents the length between the first temperature data and the second temperature data, that is, the length of the area where the cold spot is located.
The second temperature data total amount and the third temperature data total amount are similar to the first temperature data total amount, and the difference is only that the temperature data counted by the data total amount is different in the interval of the temperature data sequence. Taking the embodiment shown in fig. 2 as an example, the total amount of temperature data between the first temperature data and the second temperature data is the total amount of temperature data between the DSP and the DEP, denoted as O, and is the data of abrupt decrease from t±Δt to the ambient temperature and abrupt increase from the ambient temperature to t±Δt, respectively. The second total temperature data is the total temperature data between SP and DSP, denoted as M. The third total temperature data amount is the total temperature data amount between SP and DEP, and is M+O.
The first total amount of temperature data, that is, the number of temperature data representing the entire heat trace 1 between SP and EP, is denoted by N.
The first ratio of the total amount of the second temperature data to the total amount of the first temperature data is M/N, and the second ratio of the total amount of the third temperature data to the total amount of the first temperature data is (M+O)/N.
By determining the first ratio and the second ratio at the corresponding positions of the heat tracing pipe 1 based on the length of the heat tracing pipe 1, it is possible to determine that the position where the cold spot exists is between the first position where the end point corresponding to the SP on the heat tracing pipe 1 starts and where the length of the heat tracing pipe 1 is multiplied by the first ratio and the second position where the length of the heat tracing pipe 1 is multiplied by the second ratio.
When the temperature sensor 3 moves at a constant speed in the heat tracing pipe 1, the length of the heat tracing pipe 1 is: (first total amount of temperature data/number of times the temperature sensor 3 measures the temperature per unit time) ×average speed at which the temperature sensor 3 moves. Therefore, the step of measuring the length of the heat tracing pipe 1 can be reduced, and the heat tracing pipe 1 needing temperature measurement can be used by fixing the temperature sensor 3 on the positioning line 2, so that the convenience of the scheme provided by the embodiment of the invention is improved.
By moving the sensor at a constant speed or measuring the temperature once every a fixed period of time, the moving distance of the sensor can be determined by the speed without observing the movement of the sensor inside the heat tracing pipe 1, and the position of the cold spot on the heat tracing pipe 1 can be positioned by the above-mentioned manner without adding a distance measuring device when the sensor does not have a distance measuring function.
In another embodiment of the present invention, the length of the heat tracing pipe 1 may also be measured in advance.
The following embodiment illustrates another implementation of determining the location of the cold spot on the heat trace pipe 1.
In one embodiment of the present invention, the positions of the different temperature data may be calculated according to the length of the winding wire of the winding device 4. Since the length of the winding device 4 is fixed, the ratio of the length of the recovered positioning wire 2 to the circumference of the winding device 4 can be counted each time the temperature data is measured, so that the distance of the sensor passing through the heat tracing pipe 1 each time the temperature data is measured is obtained, and the position of the temperature sensor 3 in the heat tracing pipe 1 is further obtained.
From the above, the position where the first temperature data is located and the position where the second temperature data is located can be obtained, and the position where the cold spot exists is determined to be between the two positions.
In one embodiment of the present invention, there is also provided a heat tracing pipe temperature detection method, applied to a temperature detection device in a heat tracing pipe temperature detection system, the heat tracing pipe temperature detection system including: the heat tracing pipe 1, the positioning wire 2, the temperature sensor 3, the winding device 4 and the data processing device 5, wherein the positioning wire 2 passes through the inner side of the heat tracing pipe 1, and the temperature sensor 3 is fixed on the positioning wire 2;
A winding device 4 for controlling the positioning wire 2 and the temperature sensor 3 to move inside the heat tracing pipe 1;
A temperature sensor 3 for obtaining temperature data of each position of the heat tracing pipe 1 and transmitting the temperature data to the data processing device 5;
The heat tracing pipe temperature detection method comprises the following steps:
receiving temperature data sent by a temperature sensor 3; based on the temperature data, the position where the cold spot exists on the heat trace pipe 1 is determined.
In the scheme provided by the embodiment of the invention, by using the heat tracing pipe temperature detection system, the positioning wire 2 is controlled by the winding device 4, and then the temperature sensor 3 fixed on the positioning wire 2 is driven by the positioning wire 2 to move in the heat tracing pipe 1, so that the temperature of each position of the heat tracing pipe 1 can be conveniently measured at the inner side of the heat tracing pipe 1, and the process of controlling the movement of the temperature sensor 3 can be finished at the outer side of the heat tracing pipe 1 by the winding device 4, so that the operation is simple, and the convenience of the scheme provided by the embodiment of the invention is improved.
In addition, the obtained temperature data is directly input into the data processing device 5, and is processed by the data processing device 5 to determine the position of the cold spot, so that the temperature sensor 3 does not need to be manually taken out from the heat tracing pipe 1 to read the temperature, and the convenience of the scheme provided by the embodiment of the invention is further improved.
In the process of determining the position of the cold point in the process, the temperature data of each position inside the heat tracing pipe 1 can be obtained without disassembling the heat tracing pipe 1 or taking down the metal wire for cutting off, so that the position where the cold point exists is determined, the heat tracing pipe 1 is not damaged in the whole process, and the cost for detecting the temperature of the heat tracing pipe 1 is reduced.
The overall flow of the heat tracing pipe temperature detection method is described below with reference to the embodiment shown in fig. 3.
As shown in fig. 3, before the temperature sensor 3 is used to obtain the temperature data, detection preparation is performed, which may specifically include evacuating the gas or liquid in the heat tracing pipe 1, and removing both ends of the heat tracing pipe 1 from the apparatus or device to which the heat tracing pipe 1 is connected.
And (3) connecting the positioning ring, namely placing the positioning wire 2 into the inner side of the heat tracing pipe 1 from one end of the heat tracing pipe, enabling the positioning wire 2 to reach the other end of the heat tracing pipe 1 by means of dead weight movement or adding fluid, and connecting the two ends of the positioning wire 2 to the winding device 4 to form the positioning ring encircling the inner part and the outer part of the heat tracing pipe 1.
The temperature sensor is fixed, i.e. the temperature sensor 3 is fixed on the positioning ring.
The winding device 4 drives the positioning ring to rotate, and the temperature sensor detection position is moved.
The processing data determines the location of the cold spot, that is, the location where the cold spot exists on the heat trace pipe 1 is determined based on the temperature data of each location in the foregoing embodiments.
If the temperature is always greater than T+/-delta T in the process, namely greater than a preset temperature threshold value, no cold spot exists; if the temperature between the DSP point and the DEP point in fig. 3 is less than the temperature threshold t±Δt, then a cold point exists, and the cold point is located between M/N and (o+m)/N from the a end, which is the start point of the temperature data sequence, in the embodiment shown in fig. 1.
