Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
A line detection method of a temperature detection system according to some embodiments of the present invention is described below with reference to fig. 1 and 3.
The temperature detection system comprises a plurality of temperature sensors and a display electrically connected with the temperature sensors.
The temperature sensor is used for detecting the temperature of different positions.
The temperature sensor may include a PT100 temperature sensor.
The temperature sensors are electrically connected with the display, and the temperature values acquired by each temperature sensor are transmitted to the display through the corresponding interface and displayed by the display.
The display is used for displaying the temperature value acquired by each temperature sensor and the position information corresponding to the interface of the temperature sensor for acquiring the temperature value and the display.
A plurality of temperature values may be displayed on a display, each temperature value corresponding to a respective one of the location information.
In some embodiments, when the temperature detection system is used in a wind turbine, the temperature detection system includes: a first temperature sensor for detecting the temperature of a gear box oil pool, a second temperature sensor for detecting the temperature of a gear box high-speed shaft generator, a third sensor for detecting the temperature of a gear box lubricating oil inlet, a fourth sensor for detecting the temperature of a gear box high-speed shaft main shaft side, a fifth sensor for detecting the temperature of a gear box intermediate shaft main shaft side, a sixth sensor for detecting the temperature of a gear box intermediate shaft generator and a plurality of sensors for detecting the temperatures of other positions.
Meanwhile, the temperature value and the position information corresponding to the temperature value are correspondingly displayed on the display.
The information displayed on the display includes: the device comprises a gear box oil pool and a corresponding temperature value thereof, a gear box high-speed shaft generator and a corresponding temperature value thereof, a gear box lubricating oil inlet and a corresponding temperature value thereof, a gear box high-speed shaft main shaft side and a corresponding temperature value thereof, a gear box intermediate shaft generator and a corresponding temperature value thereof, other positions and corresponding temperature values thereof.
As shown in fig. 1, the line detection method includes:
step 110, respectively acquiring the temperature displayed by a display before and after connecting a detection resistor and a target temperature sensor to be detected in parallel, wherein the target temperature sensor is used for detecting the temperature of a first position;
step 120, determining a second location where the temperature changes based on the temperature displayed on the display;
and 130, determining that the target temperature sensor is in wrong connection under the condition that the first position is inconsistent with the second position.
In step 110, when a circuit of a certain temperature sensor in the temperature detection system needs to be detected, only one detection resistor needs to be connected in parallel to the target temperature sensor to be detected.
The target temperature sensor to be detected is used for acquiring a temperature value of a position to be detected, transmitting the temperature value to the display, and displaying position information corresponding to an interface connected with the target temperature sensor on the display while displaying the temperature value.
In the research process, the inventor finds that in the actual operation, a plurality of temperature sensors are often connected to the same display, and all the temperature values acquired by the temperature sensors are transmitted to the display and displayed, so that the temperature values displayed in the display are real-time temperatures acquired by the temperature sensors.
However, the position information corresponding to each temperature value displayed in the display is determined according to the wiring interface, when an operator makes a false connection in the wiring process, for example, the temperature sensor for detecting the position a is connected to the interface for displaying the temperature of the position B in the display, which results in that in the display process, the position information displayed in the display corresponding to the same temperature value is inconsistent with the position information actually detected by the temperature sensor corresponding to the temperature value, thereby affecting the subsequent judgment.
The inventor also finds that in the research process, in the prior art, the circuit is mostly detected in a disconnecting mode, but the method is difficult to operate due to small operation space; and the secondary disconnection easily causes loosening of the circuit, thereby causing abnormal temperature display.
In the embodiment, the detection resistor is connected with the target temperature sensor to be detected in parallel, so that the original line does not need to be removed, and the line can be rapidly detected while the original wiring and the marking mark are reserved.
When a certain temperature sensor in the temperature detection system is to be subjected to line detection, the detection resistor is connected with the target temperature sensor to be detected in parallel, and the actual position detected by the target temperature sensor to be detected is the first position.
In this step, the detection resistor should be a resistor whose resistance value is not easily changed with changes in environmental factors such as temperature, light, etc.
The detection resistor can be a constant value resistor, such as a constant value resistor with the resistance value of 250 omega, 500 omega or 1500 omega; alternatively, the detection resistor may be an adjustable resistor, such as a sliding resistor.
The resistance value of the parallel resistor changes, which results in a change in the temperature value in the display corresponding to the parallel resistor.
The larger the resistance of the detection resistor is, the smaller the resistance of the parallel resistor obtained after parallel connection is, and the larger the resistance variation amplitude is, the larger the temperature variation amplitude is, so that the observation is easier.
As shown in fig. 3, in some embodiments, the resistance of the target temperature sensor to be detected is Rp, the resistance of the detection resistor is Rt, and when the target temperature sensor to be detected is connected in parallel with the detection resistor, a parallel resistance R1 is obtained, where r1= (rp×rt)/(rp+rt).
Table 1 shows a comparison table of partial temperature and resistance values of the PT100 temperature sensor, and as can be seen from Table 1, the PT100 temperature sensor has different temperature values corresponding to different resistance values.
TABLE 1
Before the detection resistor is connected in parallel with the target temperature sensor to be detected, the resistance value of the target temperature sensor to be detected is Rp, and the temperature displayed in the corresponding display is T1;
when the detection resistor is connected in parallel with the target temperature sensor to be detected, the resistance value of the target temperature sensor to be detected is changed from Rp to R1, and the temperature displayed in the corresponding display is also changed from T1 to T2 corresponding to R1.
In step 120, when the temperature value at a certain place on the display has changed significantly after the step 110 is completed, it is determined that the position displayed on the display corresponding to the position where the temperature has changed is the second position.
The above significant changes refer to temperature changes generated by the temperature sensor during operation beyond the normal temperature fluctuation range.
For example, when the first temperature sensor at the position a is to be detected, the position a is the first position, and at this time, the temperature T collected by the first sensor is displayed on a display connected to the first temperature sensor.
The detection resistor is connected with the first temperature sensor in parallel, the resistance value of the first temperature sensor after being connected in parallel is changed, and correspondingly, the temperature on a display connected with the detection resistor is also changed, namely, the temperature is changed from T to T, and the changed position is displayed as a position B on the system, and the position B is a second position.
It should be noted that, the position information displayed in the display is determined by the display interface, and the position information displayed in the display may be consistent with the position information actually detected by the target temperature sensor to be detected, or may not be consistent.
After the first and second positions are determined, the first and second positions may be compared 130.
In some embodiments, a target temperature sensor miswiring is determined when the first location is inconsistent with the second location.
In this embodiment, the first position is the actual detection position of the target temperature sensor to be detected, which is determined by step 110, and the second position is the position displayed on the display corresponding to the position where the temperature value changes in the display after the parallel resistor is connected in the display, which is determined by step 120.
In the case of a wiring error, the corresponding temperature value is not the temperature detected by the target temperature sensor but the temperature actually detected by some other temperature sensor at the position shown on the display coincident with the detection position of the target temperature sensor.
When the resistance value of the target temperature sensor to be detected changes, one temperature value in the display connected with the target temperature sensor to be detected correspondingly changes, and the position displayed on the display corresponding to the position where the temperature changes is the other position instead of the actual detection position of the target temperature sensor.
Thus, the target temperature sensor can be confirmed for miswiring.
For example, when the temperature detection system is used for a wind driven generator and a circuit of a second temperature sensor for detecting the temperature of the gearbox high-speed shaft generator in the temperature detection system is required to be detected, the first position is determined to be the actual detection position of the second temperature sensor, namely the gearbox high-speed shaft generator.
By connecting a fixed value resistor with the resistance value of 250 omega in parallel to the second temperature sensor, a temperature value of the display is observed to be changed from 20 ℃ to-46 ℃, and the position where the temperature value is obviously changed is determined to be a second position on the display.
When the second location is not a gearbox high speed shaft generator, determining that the target temperature sensor is miswired.
According to the line detection method of the temperature detection system, the detection resistor is connected with the target temperature sensor to be detected at the first position in parallel, and the second position with the temperature changed is determined based on the temperature displayed on the display; under the condition that the first position is inconsistent with the second position, determining that the target temperature sensor is wrong in wiring, and the original wiring and marking mark can be kept without disconnecting, so that secondary damage to the wiring is avoided; and the operation is simple, and the detection efficiency is effectively improved.
In other embodiments, the target temperature sensor is determined to be properly wired if the first location coincides with the second location.
The first position is the actual detection position of the target temperature sensor to be detected, and the second position is the position displayed on the display corresponding to the position where the temperature value in the display changes after the parallel resistor is connected in the display.
And under the condition of correct wiring, the position displayed on the display is the actual detection position of the target temperature sensor.
Therefore, when the resistance value of the target temperature sensor to be detected changes, one temperature value in the display connected with the target temperature sensor to be detected correspondingly changes, and the position displayed on the display corresponding to the changed position is the actual detection position of the target temperature sensor.
For example, when the temperature detection system is used for a wind driven generator and a circuit of a third sensor for detecting the temperature of the lubricant inlet of the gearbox in the temperature detection system is required to be detected, the first position is determined to be the actual detection position of the third temperature sensor, namely the lubricant inlet of the gearbox.
And (3) by connecting a fixed value resistor with the resistance value of 250 omega in parallel to the third temperature sensor, observing the position of the display where the temperature value changes obviously, and determining the position where the temperature value changes obviously as a second position.
When the second position is the gearbox lubrication oil inlet, the target temperature sensor is determined to be correctly wired.
According to the line detection method of the temperature detection system, the detection resistor is connected with the target temperature sensor to be detected at the first position in parallel, and the second position with the temperature changed is determined based on the temperature displayed on the display; under the condition that the first position is consistent with the second position, the fact that the target temperature sensor is correctly connected is determined, disconnection is not needed, and secondary damage to the circuit is avoided; and the operation is simple, and the detection efficiency is effectively improved.
In still other embodiments, the target temperature sensor is determined to be faulty in the event that none of the temperatures shown on the display change.
In this embodiment, after the detection resistor is connected in parallel, it means that the resistance value of the detected target temperature sensor changes, if the temperature displayed in the display does not change, it means that no current flows into the detection resistor, and it means that the target temperature sensor to be detected fails.
According to the line detection method of the temperature detection system provided by the embodiment of the invention, the detection resistor is connected in parallel with the target temperature sensor to be detected, the temperature value displayed in the display is changed by changing the resistance value of the parallel resistor, whether the line is faulty or not is judged by observing whether the temperature value in the display changes or not, disconnection is not needed, and secondary damage to the line is avoided; and the operation is simple, and the detection efficiency is effectively improved.
In some embodiments, the parallel connection may be performed by contacting pins of the detection resistor with both ends of the target temperature sensor.
In the embodiment, the pins of the detection resistor are in touch connection with the two ends of the target temperature sensor, so that the screw cannot be loosened, and the operation is simple and quick.
In other embodiments, the pins of the detection resistor may be connected in parallel by connecting the pins to both ends of the target temperature sensor through the holding member or the elastic connection member.
Compared with the touch connection, the connection can be firmer by connecting the holding part or the elastic connecting part with the two ends of the target temperature sensor, so that the measured temperature value is more stable and easier to observe and judge.
However, the present invention is not limited thereto, and in actual operation, an optimal connection method may be selected according to actual needs.
According to the line detection method of the temperature detection system, provided by the embodiment of the invention, the detection resistor and the target temperature sensor are connected in a plurality of parallel modes, so that screw loss caused by secondary disassembly and assembly lines is avoided, the operation is simple and quick, and the efficiency is improved by more than 80%.
The line detection device of the temperature detection system provided in some embodiments of the present invention will be described below, and the line detection device of the temperature detection system described below and the line detection method of the temperature detection system described above may be referred to correspondingly to each other.
The temperature detection system comprises a plurality of temperature sensors and a display connected with the temperature sensors.
As shown in fig. 4, the line detection device of the temperature detection system includes: a first acquisition module 410, a second acquisition module 420, and a determination module 430.
A first obtaining module 410, configured to obtain temperatures displayed by the display before and after connecting the detection resistor and the target temperature sensor to be detected in parallel, where the target temperature sensor is used to detect a temperature at a first position;
a second acquisition module 420 for determining second location information of a temperature change based on the temperature displayed on the display;
and a determining module 430, configured to determine that the target temperature sensor is in a wrong connection if the first location information is inconsistent with the second location information.
In some embodiments, the determining module 430 is further configured to determine that the target temperature sensor is properly wired if the first location is consistent with the second location.
In some embodiments, the determining module 430 is further configured to determine that the target temperature sensor is in error if none of the temperatures displayed on the display change.
In some embodiments, connecting a detection resistor in parallel with a target temperature sensor to be detected includes:
The pins of the detection resistor are contacted with two ends of the target temperature sensor;
or,
and the pins of the detection resistor are connected with two ends of the target temperature sensor through the clamping component or the elastic connecting component.
According to the line detection device of the temperature detection system, provided by the embodiment of the invention, the detection resistor is connected with the target temperature sensor to be detected at the first position in parallel to change the resistance value and further change the temperature value displayed at the second position, and the first position and the second position are compared to be inconsistent, so that the wiring error of the first position can be confirmed, the disconnection is not needed, and the secondary damage to the line is not caused; and the operation is simple, and the detection efficiency is effectively improved.
The following describes a line detection method of a temperature detection system according to other embodiments of the present invention with reference to fig. 2 and 3.
The temperature detection system comprises a plurality of temperature sensors and a display connected with the temperature sensors.
The temperature sensor is used for detecting the temperature of different positions.
The temperature sensor may include a PT100 temperature sensor.
The temperature sensors are electrically connected with the display, and the temperature value acquired by each temperature sensor is transmitted to the display and displayed by the display.
The display is used for displaying the temperature value acquired by each temperature sensor and the position information displayed on the display corresponding to the temperature value.
A plurality of temperature values may be displayed on one display, each temperature value corresponding to the positional information displayed on one display.
In some embodiments, when the temperature detection system is used in a wind turbine, the temperature detection system includes: a first temperature sensor for detecting the temperature of a gear box oil pool, a second temperature sensor for detecting the temperature of a gear box high-speed shaft generator, a third sensor for detecting the temperature of a gear box lubricating oil inlet, a fourth sensor for detecting the temperature of a gear box high-speed shaft main shaft side, a fifth sensor for detecting the temperature of a gear box intermediate shaft main shaft side, a sixth sensor for detecting the temperature of a gear box intermediate shaft generator and a plurality of sensors for detecting the temperatures of other positions.
Meanwhile, the temperature value and the position information corresponding to the temperature value are correspondingly displayed on the display.
The information displayed on the display includes: the device comprises a gear box oil pool and a corresponding temperature value thereof, a gear box high-speed shaft generator and a corresponding temperature value thereof, a gear box lubricating oil inlet and a corresponding temperature value thereof, a gear box high-speed shaft main shaft side and a corresponding temperature value thereof, a gear box intermediate shaft generator and a corresponding temperature value thereof, other positions and corresponding temperature values thereof.
As shown in fig. 2, the line detection method of the temperature detection system includes:
step 210, acquiring a first temperature value displayed on a display by a target temperature sensor to be detected;
step 220, under the condition that the detection resistor is connected with the target temperature sensor in parallel, acquiring a second temperature value displayed by the target temperature sensor on the display;
in step 230, if the deviation of the first temperature value and the second temperature value is less than the target deviation, determining that the target temperature sensor is miswired.
In step 210, the first temperature value is a temperature value displayed on the display corresponding to a position corresponding to a detection position of the target temperature sensor to be detected.
In the research process, the inventor finds that in the actual operation, a plurality of temperature sensors are often connected to the same display, and all the temperature values acquired by the temperature sensors are transmitted to the display and displayed, so that the temperature values displayed in the display are real-time temperatures acquired by the temperature sensors.
But the position information displayed on the display corresponding to each temperature value in the display is consistent with the position information corresponding to the display interface. When an operator misconnects in the wiring process, the position information displayed in the display corresponding to the same temperature value is inconsistent with the position information actually detected by the temperature sensor corresponding to the temperature value in the display process.
Therefore, in this step, the first temperature value may coincide with the temperature measured by the target temperature sensor to be detected, or may not coincide with the temperature measured by the target temperature sensor to be detected.
In step 220, the detection resistor is first connected in parallel to the target temperature sensor to be detected, and then a second temperature value displayed by the target temperature sensor on the display is acquired.
The second temperature value is a temperature value corresponding to a position, which is displayed on the display and corresponds to the detection position of the target temperature sensor to be detected, after the target temperature sensor to be detected is connected in parallel with the detection resistor.
After the target temperature sensor to be detected is connected with the detection resistor in parallel, the resistance value of the resistor after the parallel connection is changed, so that the temperature displayed in the display is changed.
For example, when the resistance value of the target temperature sensor to be detected is Rp, the corresponding temperature under the resistance value is T1; after a detection resistor with a resistance value Rt is connected in parallel, the resistance value after the parallel connection becomes R1, where r= (rp×rt)/(rp+rt), and the corresponding temperature under the resistance value becomes T2 accordingly.
After the first temperature value and the second temperature value are determined, whether the wiring of the target temperature sensor to be detected is faulty or not can be judged by comparing the first temperature value and the second temperature value.
According to some embodiments of the invention, in step 230, a target temperature sensor miswiring is determined in the event that the deviation of the first temperature value and the second temperature value is less than the target deviation.
In this embodiment, the first temperature value is determined by step 210, and the temperature value corresponding to the position information displayed on the display corresponding to the detection position of the target temperature sensor to be detected in the display is determined before the parallel resistor is connected.
The second temperature value is determined by step 220, and after the parallel resistor is connected, the temperature value displayed in the display corresponds to the position where the target temperature sensor to be detected is detected.
The target deviation is a section in which the temperature value detected by each temperature sensor shows natural fluctuation in the execution process of the temperature detection system.
The inventor finds that the temperature of the detection position of each temperature sensor changes in real time in the research and development process, and the circuit also emits heat in the working process, so that the temperature value of the corresponding position in the display changes in real time, but the fluctuation range is always kept in a certain interval.
In this step, by setting a target deviation, it is used to distinguish the natural fluctuation range of the temperature sensor from the temperature change due to the resistance change after the parallel detection of the resistance.
For example, before the target temperature sensor to be detected is connected in parallel with the detection resistor, the resistance value of the target temperature sensor to be detected is Rp, and at this time, the first temperature value is the temperature value T1 displayed in the display and corresponding to the position C where the actual detection position C of the target temperature sensor to be detected is consistent.
After the target temperature sensor to be detected is connected in parallel with the detection resistor, when the resistance value of the detection resistor is Rt, the resistance value of the target temperature sensor to be detected after being connected in parallel is changed from Rp to R1, wherein R1= (Rp x Rt)/(Rp+Rt).
The temperature value in the display is changed due to the change of the resistance value, so that the second temperature value is the corresponding temperature value T2 at the position C displayed in the display.
The target deviation at position C is set to epsilon.
When the deviation of the first temperature value T1 and the second temperature value T2 is smaller than the target deviation epsilon, it is indicated that the temperature change on the display is caused by the temperature fluctuation naturally generated in the working process of the temperature sensor, but not by the temperature change caused by the change of the resistance value of the resistors after the parallel connection.
It is possible to determine that the temperature value detected by the target temperature sensor is not the same temperature value as the temperature value corresponding to the position shown in the display in correspondence with the detection position of the target temperature sensor, that is, the target temperature sensor is miswired.

In other embodiments, the target temperature sensor is determined to be properly wired if the deviation of the first temperature value and the second temperature value is not less than the target deviation.
In this embodiment, when the deviation between the first temperature value and the second temperature value is not less than the target deviation, it is indicated that the temperature change on the display at this time is a temperature change caused by the change of the resistance value after the parallel detection resistor is connected.
Therefore, the temperature value detected by the target temperature sensor can be determined, and the temperature value corresponding to the position which is displayed in the display and is consistent with the detection position of the target temperature sensor is the same temperature value, namely, the target temperature sensor is correctly connected.
According to the line detection method of the temperature detection system provided by the embodiment of the invention, the detection resistor is connected in parallel with the target temperature sensor to be detected, so that the first temperature corresponding to the same position displayed in the display before parallel connection and the second temperature corresponding to the same position displayed in the display after parallel connection are determined, the deviation between the first temperature and the second temperature is not less than the target deviation, the correct wiring of the target temperature sensor to be detected can be confirmed, the wire stripping is not needed, the original wiring and scribing mark can be kept, and the secondary damage to the line is avoided; and the operation is simple, and the detection efficiency is effectively improved.
In some embodiments, the parallel connection may be performed by contacting pins of the detection resistor with both ends of the target temperature sensor.
In the embodiment, the pins of the detection resistor are in touch connection with the two ends of the target temperature sensor, so that the screws and the lines cannot be loosened, and the operation is simple and quick.
In other embodiments, the pins of the detection resistor may be connected in parallel by connecting the pins to both ends of the target temperature sensor through the holding member or the elastic connection member.
