Description

Technical Field

[0001] The present invention belongs to the technical field of lighting sources, specifically relates to light emitting diodes, and more particularly to a livestock drug concentration detection system and a detection method for livestock biotechnology. Background Art

[0002] Optical drug concentration detection uses light of a specific wavelength to illuminate the liquid drug and quantitatively determine the concentration based on the Lambert-Beer law (absorbance is proportional to concentration).

[0003] LED light intensity varies with temperature, primarily due to the junction temperature (Tj). When the junction temperature rises, the luminous efficiency decreases, which in turn causes the emission wavelength to redshift and the light intensity to attenuate, making it impossible to accurately detect the concentration of livestock pesticides.

[0004] In order to ensure the stability of LED light sources, a constant current source is generally used. In order to reduce power supply fluctuations as much as possible, this application uses a resistor shunt current source. The output of the power supply is changed by changing the resistor load, reducing the use of transistors and further improving the stability of the power supply. Due to the electrothermal effect of the resistor, the resistor will heat up over time, and the heat will affect the output of the power supply.

[0005] Therefore, due to the technical problem that the concentration of animal husbandry drugs cannot be accurately detected due to the red shift of LED emission wavelength caused by temperature increase, it is necessary to design a animal husbandry drug concentration detection system and detection method for animal husbandry biotechnology. It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art. Summary of the Invention

[0007] In a first aspect, the present disclosure provides a system for detecting concentration of livestock medicines for livestock biotechnology, comprising: A control module, and a light-emitting diode mechanism and a receiving mechanism electrically connected to the control module; The control module is configured to control the light emitting diode mechanism to emit light, which passes through the livestock medicine to be tested and is received by the receiving mechanism, and the absorbance of the livestock medicine to be tested is determined based on the light to determine the concentration of the livestock medicine to be tested; wherein The light emitting diode mechanism includes: a temperature sensitive resistor and at least two constant current source modules; The constant current source module is a resistive constant current source; The constant current source module is electrically connected to the control module; The temperature-sensitive resistor is electrically connected to the two constant current source modules via a relay; The control module is configured so that when one constant current source module supplies power to the light-emitting diode, the other constant current source module is electrically connected to the temperature-sensitive resistor, so as to adjust the current output by the constant current source by changing the resistance value of the temperature-sensitive resistor to judge the current temperature of the light-emitting diode, and control the two constant current source modules to alternately supply power to the light-emitting diodes in the light-emitting diode mechanism according to the temperature.

[0008] In an optional embodiment, the constant current source module includes: a constant current source chip; The temperature-sensitive resistor is electrically connected to the two constant current source chips through the two first switch modules; The constant current source chip is electrically connected to the corresponding first resistor through the second switch module, and the resistance value of the first resistor is fixed so that the constant current source chip outputs a constant current; The first switch module and the second switch module are both electrically connected to the control module; The constant current source chip is electrically connected to the light-emitting diode and the current detection circuit. The constant current source chip outputs a constant current to the light-emitting diode to drive the light-emitting diode to light up. The constant current source chip outputs current to the current detection circuit to determine the temperature of the light-emitting diode at this time based on the current.

[0009] In an optional embodiment, when a constant current source chip outputs a constant current to a light-emitting diode, the control module controls the corresponding second switch module to operate so that the constant current source chip is electrically connected to the corresponding first resistor, and controls the corresponding first switch module to operate so that the temperature-sensitive resistor is disconnected from the constant current source chip. At the same time, the control module controls the second switch module corresponding to another constant current source chip to operate so that the corresponding first resistor is disconnected from the constant current source chip, and controls the corresponding first switch module to operate so that the temperature-sensitive resistor is electrically connected to the constant current source chip.

[0010] In an optional embodiment, when the light-emitting diode is working, the temperature increases, causing the resistance of the thermistor to change, and the current output by the constant current source chip connected to the thermistor changes with the temperature. At this time, the current output by the constant current source chip is detected in real time by the current detection circuit, and the detected current is sent to the control module. The control module determines the temperature of the light-emitting diode through the current.

[0011] In an optional embodiment, when the constant current source chip is electrically connected to the temperature-sensitive resistor, the second power supply connected to the temperature-sensitive resistor simultaneously supplies power to the constant current source chip; When the constant current source chip is electrically connected to the first resistor, the first power supply supplies power to the constant current source chip, so that the constant current source chip provides a constant current to the light emitting diode to drive the light emitting diode to emit light; The voltage provided by the first power supply is greater than the voltage provided by the second power supply.

[0012] In an optional embodiment, the control module is configured to judge the temperature of the light-emitting diode in real time through the current output by another constant current source chip when a constant current source chip provides a constant current to the light-emitting diode, obtain an actual curve corresponding to the actual temperature of the light-emitting diode and the working time, and compare it with a preset standard curve. If the actual curve does not match the standard curve, that is, the current actual temperature of the light-emitting diode is greater than the corresponding temperature in the preset standard curve, the control module controls the constant current source chip currently electrically connected to the thermistor to disconnect from the thermistor, and then re-electrically connect to the corresponding first resistor to provide a constant current to the light-emitting diode. The other constant current source chip is disconnected from the corresponding first resistor and then connected to the thermistor, completing the switching of the constant current source chip to provide a constant current to the light-emitting diode.

[0013] In an optional embodiment, the control module is also configured to determine whether the current temperature of the light-emitting diode has changed if the current temperature of the light-emitting diode is still higher than the temperature corresponding to the preset standard curve after the constant current source chip that provides constant current to the light-emitting diode is switched. If it has changed, it is determined that the thermistor is normal; if it has not changed, it is determined that the thermistor is damaged, and the control module then issues an alarm.

[0014] In an optional embodiment, the control module is further configured to control the radiator to gradually increase the heat dissipation power when the temperature sensitive resistor is normal. If the current temperature of the light-emitting diode drops to the temperature corresponding to the preset standard curve after the heat dissipation power of the radiator is increased, the control module records the heat dissipation power of the radiator at this time. If the current temperature of the light-emitting diode is still higher than the temperature corresponding to the preset standard curve after the radiator is increased to the maximum heat dissipation power, the light-emitting diode is judged to be abnormal, and the control module then issues an alarm.

[0015] In an optional embodiment, the control module is electrically connected to a radiator, and the control module is configured to control the radiator to operate when the light emitting diode is operating to dissipate heat.

[0016] In a second aspect, the present disclosure also provides a detection method using the above-mentioned livestock drug concentration detection system for livestock biotechnology, comprising: The control module controls the light emitting diode mechanism to emit light, and the light is received by the receiving mechanism after passing through the animal husbandry medicine to be tested. The absorbance of the animal husbandry medicine to be tested is determined according to the light to determine the concentration of the animal husbandry medicine to be tested; During the process of the light-emitting diode mechanism emitting light, the control module controls the two constant current source modules to alternately power the light-emitting diodes in the light-emitting diode mechanism, and when one constant current source module powers the light-emitting diode, the other constant current source module is electrically connected to the temperature-sensitive resistor to adjust the current output by the constant current source according to the change in the resistance value of the temperature-sensitive resistor to determine the current temperature of the light-emitting diode.

[0017] The beneficial effects of the present invention are as follows: the livestock medicine concentration detection system for livestock biotechnology comprises: a control module, and a light-emitting diode mechanism and a receiving mechanism electrically connected to the control module; the control module is configured to control the light-emitting diode mechanism to emit light, which passes through the livestock medicine to be detected and is received by the receiving mechanism, and the absorbance of the livestock medicine to be detected is judged according to the light to judge the concentration of the livestock medicine to be detected; wherein the light-emitting diode mechanism comprises: a temperature-sensitive resistor and at least two constant current source modules; the constant current source module is electrically connected to the control module; the temperature-sensitive resistor is connected to the livestock medicine through a relay The electrical appliance is electrically connected to both constant current source modules; the control module is configured so that when one constant current source module supplies power to the light-emitting diode, the other constant current source module is electrically connected to the temperature-sensitive resistor, so as to adjust the current output by the constant current source by changing the resistance value of the temperature-sensitive resistor, so as to judge the current temperature of the light-emitting diode, and control the two constant current source modules to alternately supply power to the light-emitting diode in the light-emitting diode mechanism according to the temperature, thereby realizing that the two constant current source modules alternately supply power to the light-emitting diode according to the temperature, avoiding the red shift of the light-emitting wavelength caused by excessive temperature of the light-emitting diode, and thus avoiding the inability to accurately detect the concentration of the livestock drug.

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration."

Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0024] Concentration testing of livestock drugs relies on the characteristic UV absorption of the active ingredient in liquid veterinary drugs at specific wavelengths, quantified using the Lambert-Beer law (absorbance is proportional to concentration). This method requires no complex pre-treatment and is suitable for drugs containing aromatic rings and conjugated double bonds (such as common veterinary drug ingredients like sulfonamides, quinolones, and tetracyclines). Therefore, an LED light is used to illuminate the drug and determine its concentration by observing its absorbance. However, the inventors discovered that LED light intensity varies with temperature. The temperature effect on LED light intensity is essentially due to a decrease in luminous efficiency caused by an increase in junction temperature (Tj). When an LED is operating, approximately 70% of the electrical energy is converted into heat. For every 10°C increase in junction temperature, luminous efficiency can decrease by 10%-15%. The semiconductor band gap decreases with temperature, resulting in a red shift in the emission wavelength and a decrease in light intensity. If the LED driver circuit does not utilize constant current control, temperature fluctuations can cause changes in the LED's forward voltage (Vf), thus affecting the actual operating current.

[0025] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0027] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0028] like Figure 1As shown, at least one disclosed embodiment provides a livestock drug concentration detection system for livestock biotechnology, comprising: a control module, and a light-emitting diode mechanism and a receiving mechanism electrically connected to the control module; the control module is configured to control the light-emitting diode mechanism to emit light, which passes through the livestock drug to be tested and is received by the receiving mechanism, and the absorbance of the livestock drug to be tested is judged based on the light to judge the concentration of the livestock drug to be tested; wherein the light-emitting diode mechanism comprises: a temperature-sensitive resistor and at least two constant current source modules; the constant current source module is electrically connected to the control module; the temperature-sensitive resistor The control module is electrically connected to two constant current source modules through a relay; the control module is configured so that when one constant current source module supplies power to the light-emitting diode, the other constant current source module is electrically connected to the temperature-sensitive resistor, so as to adjust the current output by the constant current source according to the change in the resistance value of the temperature-sensitive resistor, so as to judge the current temperature of the light-emitting diode, and control the two constant current source modules to alternately supply power to the light-emitting diode in the light-emitting diode mechanism according to the temperature, thereby realizing that the two constant current source modules alternately supply power to the light-emitting diode according to the temperature, avoiding the red shift of the light-emitting wavelength caused by the light-emitting diode being too high, and thus avoiding the inability to accurately detect the concentration of the livestock drug.

[0029] like Figure 5 As shown, in this embodiment, the constant current source module is a resistive constant current source; by controlling the resistance in the power supply, the output current is changed, but this method drives a small current and cannot drive devices with higher power. Generally, devices with power below 100w can achieve the best use effect. The power module in this application is used to power the light-emitting diode mechanism and is within the scope of application.

[0030] In this embodiment, at the same time, one constant current source module supplies power to the light emitting diode mechanism, and another constant current source module detects the temperature of the light emitting diode mechanism.

[0031] In this embodiment, the receiving mechanism may be, but is not limited to, an absorbance detection module.

[0032] In this embodiment, when the light emitting diode starts to emit light, the constant current module that provides constant current to the light emitting diode is the constant current module that detects the temperature of the light emitting diode when the light emitting diode stops working last time.

[0033] like Figure 2As shown, in an optional embodiment, the constant current source module includes: a constant current source chip; the temperature-sensitive resistor is electrically connected to the two constant current source chips through two first switch modules; the constant current source chip is electrically connected to the corresponding first resistor through the second switch module, and the resistance of the first resistor is fixed so that the constant current source chip outputs a constant current; the first switch module and the second switch module are both electrically connected to the control module; the constant current source chip is electrically connected to the light-emitting diode and the current detection circuit, the constant current source chip outputs a constant current to the light-emitting diode to drive the light-emitting diode to light up, and the constant current source chip outputs current to the current detection circuit to judge the temperature of the light-emitting diode at this time according to the current.

[0034] In this embodiment, the model of the constant current source chip may be, but is not limited to, XL2596S-5.0E1.

[0035] In this embodiment, the constant current source chip is connected to or disconnected from the temperature-sensitive resistor by controlling the first switch module, and the first resistor is connected to or disconnected from the constant current source chip by controlling the second switch module.

[0036] In this embodiment, when the constant current source chip is electrically connected to the first resistor, it is disconnected from the temperature sensitive resistor. At this time, the constant current source chip is connected to the first power source to provide a constant current to the light emitting diode.

[0037] In this embodiment, when the constant current source chip is electrically connected to the temperature sensitive resistor, it is disconnected from the first resistor. At this time, the constant current source chip is connected to the second power supply, and the current output by the constant current source chip is obtained through the current detection circuit. The temperature at this time, that is, the temperature of the light-emitting diode, is judged according to the current value.

[0038] In an optional embodiment, when a constant current source chip outputs a constant current to a light-emitting diode, the control module controls the corresponding second switch module to operate so that the constant current source chip is electrically connected to the corresponding first resistor, and controls the corresponding first switch module to operate so that the temperature-sensitive resistor is disconnected from the constant current source chip. At the same time, the control module controls the second switch module corresponding to another constant current source chip to operate so that the corresponding first resistor is disconnected from the constant current source chip, and controls the corresponding first switch module to operate so that the temperature-sensitive resistor is electrically connected to the constant current source chip.

[0039] In an optional embodiment, when the light-emitting diode is working, the temperature increases, causing the resistance of the thermistor to change, and the current output by the constant current source chip connected to the thermistor changes with the temperature. At this time, the current output by the constant current source chip is detected in real time by the current detection circuit, and the detected current is sent to the control module. The control module determines the temperature of the light-emitting diode through the current.

[0040] In an optional embodiment, when the constant current source chip is electrically connected to the thermistor, the second power supply connected to the thermistor also supplies power to the constant current source chip; when the constant current source chip is electrically connected to the first resistor, the first power supply supplies power to the constant current source chip, so that the constant current source chip provides a constant current to the light-emitting diode to drive the light-emitting diode to emit light; the voltage provided by the first power supply is greater than the voltage provided by the second power supply.

[0041] In this embodiment, when the constant current source chip is connected to the temperature-sensitive resistor, it is powered by a second power supply, and the voltage of the second power supply is relatively small. At this time, the constant current source chip is in a working state but the load is relatively small, and the capacitors, inductors, etc. around the constant current source chip are in a working state through the second power supply. In this way, when it is necessary to switch the constant current source chip to power the light-emitting diode, the constant current source chip in the temperature-sensitive resistor can be directly switched to power the light-emitting diode, so that the light-emitting diode is in a stable lighting state; there are various capacitors, inductors and other modules around the constant current source chip. In the related art, when the non-working constant current source chip is directly switched to power the light-emitting diode, the short-term current output is unstable because power supply needs to be supplied first to make the capacitors, inductors, etc. around the constant current source chip start working, which does not meet the requirements of stable operation of the light-emitting diode. When the constant current source chip is switched, the light-emitting diode is already in a working state and has been working for a period of time. The constant current source chip must switch stably when switching, so the capacitors, inductors, etc. around the constant current source chip must be started to stabilize the output current.

[0042] like Figure 3 As shown, in an optional embodiment, the control module is configured to judge the temperature of the light-emitting diode in real time through the current output by another constant current source chip when a constant current source chip provides a constant current to the light-emitting diode, obtain the actual curve corresponding to the actual temperature of the light-emitting diode and the working time, and compare it with the preset standard curve. If the actual curve does not match the standard curve, that is, the current actual temperature of the light-emitting diode is greater than the corresponding temperature in the preset standard curve, the control module controls the constant current source chip currently electrically connected to the thermistor to disconnect from the thermistor, and then re-electrically connect to the corresponding first resistor to provide a constant current to the light-emitting diode. The other constant current source chip is disconnected from the corresponding first resistor and then connected to the thermistor, completing the switching of the constant current source chip to provide a constant current to the light-emitting diode.

[0043] In this embodiment, a preset standard curve is stored in the storage module electrically connected to the control module. The standard curve can reflect the change of the standard temperature of the light emitting diode over time after operation.

[0044] like Figure 4As shown, in an optional embodiment, the control module is further configured to determine whether the current temperature of the light-emitting diode has changed if the current temperature of the light-emitting diode is still higher than the temperature corresponding to the preset standard curve after the constant current source chip that provides constant current to the light-emitting diode is switched. If it has changed, it is determined that the thermistor is normal; if it has not changed, it is determined that the thermistor is damaged, and the control module then issues an alarm.

[0045] In an optional embodiment, the control module is further configured to control the radiator to gradually increase the heat dissipation power when the temperature sensitive resistor is normal. If the current temperature of the light-emitting diode drops to the temperature corresponding to the preset standard curve after the heat dissipation power of the radiator is increased, the control module records the heat dissipation power of the radiator at this time. If the current temperature of the light-emitting diode is still higher than the temperature corresponding to the preset standard curve after the radiator is increased to the maximum heat dissipation power, the light-emitting diode is judged to be abnormal, and the control module then issues an alarm.

[0046] In this embodiment, when the radiator can reduce the temperature of the LED to meet the standard curve at a certain power level, the control module can record the power level at that level and directly control the radiator to dissipate heat at that power level the next time the LED starts working.

[0047] In this embodiment, the heat dissipation power level of the radiator can be set to multiple levels. When the current temperature of the light emitting diode cannot meet the standard curve, the power of the radiator is increased step by step to enhance the heat dissipation effect.

[0048] In this embodiment, when the light emitting diode starts to work, the control module synchronously controls the radiator to start working to dissipate heat. At this time, the lowest power level can be used for heat dissipation.

[0049] In an optional embodiment, the control module is electrically connected to a radiator, and the control module is configured to control the radiator to operate when the light emitting diode is operating to dissipate heat.

[0050] In this embodiment, the constant current source chip is switched to provide a stable current to the light-emitting diode, which can avoid the temperature generated when a constant current source chip provides a stable current to the light-emitting diode for a long time from affecting the light-emitting diode. When the constant current source chip is switched, the temperature of the new constant current source chip used to provide a stable current is lower.

[0051] At least one other disclosed embodiment further provides a detection method using the above-mentioned livestock drug concentration detection system for livestock biotechnology, comprising: The control module controls the light emitting diode mechanism to emit light, and the light is received by the receiving mechanism after passing through the animal husbandry medicine to be tested. The absorbance of the animal husbandry medicine to be tested is determined according to the light to determine the concentration of the animal husbandry medicine to be tested; During the process of the light-emitting diode mechanism emitting light, the control module controls the two constant current source modules to alternately power the light-emitting diodes in the light-emitting diode mechanism, and when one constant current source module powers the light-emitting diode, the other constant current source module is electrically connected to the temperature-sensitive resistor to adjust the current output by the constant current source according to the change in the resistance value of the temperature-sensitive resistor to determine the current temperature of the light-emitting diode.

[0052] In summary, the livestock drug concentration detection system for livestock biotechnology includes: a control module, and a light-emitting diode mechanism and a receiving mechanism electrically connected to the control module; the control module is configured to control the light-emitting diode mechanism to emit light, and the light is received by the receiving mechanism after passing through the livestock drug to be tested, and the absorbance of the livestock drug to be tested is judged according to the light to judge the concentration of the livestock drug to be tested; wherein the light-emitting diode mechanism includes: a temperature-sensitive resistor and at least two constant current source modules; the constant current source module is electrically connected to the control module; the temperature-sensitive resistor is connected to the receiving mechanism through a relay The two constant current source modules are electrically connected; the control module is configured so that when one constant current source module supplies power to the light-emitting diode, the other constant current source module is electrically connected to the temperature-sensitive resistor, so as to adjust the current output by the constant current source according to the change in the resistance value of the temperature-sensitive resistor to judge the current temperature of the light-emitting diode, and control the two constant current source modules to alternately supply power to the light-emitting diode in the light-emitting diode mechanism according to the temperature, thereby realizing that the two constant current source modules alternately supply power to the light-emitting diode according to the temperature, avoiding the red shift of the light-emitting wavelength caused by the light-emitting diode being too high, and thus avoiding the inability to accurately detect the concentration of the livestock drug.
