[0057] Embodiment 1:

[0058] For the existing measuring device of phthalates in textiles, the phthalates content in textiles is generally measured by gas chromatography-mass spectrometer 2 or biological method based on degradation bacteria 10. Although the phthalates content in textiles can be accurately measured by gas chromatography-mass spectrometer 2, there are problems of cumbersome pre-processing steps and long measuring time, which cannot meet the needs of some users to quickly measure whether there are phthalates in textiles, or roughly measure phthalates. The method of measuring the phthalates content in textiles by biological method based on degradation bacteria 10 has the problem of low measuring accuracy due to too many objective interference factors, which cannot meet the needs of users to accurately measure the phthalates content in textiles. For this reason, it is necessary to develop a measuring device and its use method that can automatically select a matching phthalates measuring device according to the different measuring accuracy requirements of users for the phthalates content in textiles.

[0059] In order to solve the technical problems existing in the prior art, this embodiment provides a device for determining phthalates in textiles, such as Figure 1 As shown, it includes at least one data processing center 1 and at least two different types of phthalate determination equipment. The data processing center 1 is used to obtain basic demand data of users, obtain basic demand characteristics according to the basic demand data, and calculate the phthalate determination accuracy preference according to the basic demand characteristics, control the action of the phthalate determination equipment that matches the phthalate determination accuracy preference, and realize the determination of phthalates in the textile to be tested.

[0060] Wherein, the phthalate determination device is used to achieve the determination of phthalates in textiles. Preferably, the at least two different types of phthalate determination devices include a first determination device for determining phthalates based on a biological method and a second determination device for determining phthalates based on a chemical method.

[0061] The first determination device is based on the biological method for determining phthalates, and is configured to quickly determine whether the textile to be tested contains phthalates, and to roughly determine the phthalate content in the textile to be tested. The second determination device is based on the chemical method for determining phthalates, and is configured to accurately determine the phthalate content in the textile to be tested, for example, the phthalate content in the textile to be tested can be determined by a gas chromatography-mass spectrometry instrument or a liquid chromatography-mass spectrometry instrument with high sensitivity and accuracy.

[0062] In short, the first measuring device is suitable for occasions where the measurement accuracy of phthalates is not required to be high, and the second measuring device is suitable for occasions where the measurement accuracy of phthalates is required to be high.

[0063] Preferably, the data processing center 1 and at least two different types of phthalate determination equipment are installed together, and the phthalate determination equipment is connected to the data processing center 1 in communication. At least two different types of phthalate determination equipment are configured to automatically determine the phthalate content in the textile to be tested according to the control instructions of the data processing center 1. That is to say, the phthalate determination equipment is a fully automatic phthalate content determination equipment, including the most basic textile pretreatment components to be tested (such as crushing, weighing, dissolving in water samples, etc.) and the phthalate content determination components of the textile to be tested after pretreatment (such as gas chromatography-mass spectrometer 2). Since the equipment for fully automatic measurement of the phthalate content of textiles based on biological methods or chemical methods belongs to the conventional technical means in this field, it is not repeated here.

[0064] The basic demand data refers to information data associated with the preference for phthalate determination accuracy, including but not limited to the user's identity information, the type of textile to be tested, past measurement accuracy requirements, etc. The user's identity information is associated with his or her identity and occupation, which can reflect his or her preference for the measurement accuracy of phthalates in textiles to a certain extent. The type of textile to be tested and past measurement accuracy requirements are also closely related to the measurement accuracy of phthalates in textiles.

[0065] The phthalate measurement accuracy preference is calculated according to the basic demand characteristics, and the actual measurement accuracy requirement of the user can be obtained. Therefore, based on the calculated phthalate measurement accuracy preference, the action of the phthalate measurement device that matches the phthalate measurement accuracy preference is controlled, and the matching phthalate measurement device can be automatically selected according to the different measurement accuracy requirements of the user for the phthalate content in the textile.

[0066] Preferably, the measurement accuracy of at least two different types of phthalate determination devices is different. The device for determining phthalates in textiles also includes a user terminal bound to a user identity. Before controlling the action of the phthalate determination device that matches the phthalate determination accuracy preference to achieve the determination of phthalates in the textile to be measured, the data processing center 1 first sends the calculated phthalate determination accuracy preference and the relevant information of the selected matching phthalate determination device such as type, parameters, measurement time, measurement fee, etc. to the user terminal. After receiving the confirmation instruction fed back by the user terminal or after exceeding the preset waiting time without receiving the feedback from the user terminal, the data processing center 1 controls the action of the phthalate determination device that matches the phthalate determination accuracy preference to achieve the determination of phthalates in the textile to be measured. If there is a phthalate determination device of the user specified type in the feedback information of the user terminal received by the data processing center 1, the action of the phthalate determination device of the user specified type is controlled to automatically achieve the determination of the phthalate content in the textile. In this way, by setting a user terminal, the action of the phthalate determination device that matches the phthalate determination accuracy preference is controlled, so that before the phthalate in the textile to be measured is measured, the user's feedback information is first obtained, and the phthalate content in the textile is measured based on the feedback information. On the one hand, the intelligence level of the entire phthalate determination device in the textile is improved, and on the other hand, the matching phthalate determination device can be automatically selected according to the different measurement accuracy requirements of the user for the phthalate content in the textile.

[0067] Preferably, the processing center includes a feature extraction unit and a preference calculation unit.

[0068] The feature extraction unit is used to obtain the basic demand data and extract the basic demand features from the basic demand data. The preference calculation unit is used to calculate the phthalate determination accuracy preference according to the basic demand features.

[0069] In summary, the device for determining phthalates in textiles calculates the user's preference for phthalates determination accuracy and selects a matching phthalates determination device. It can automatically complete the determination of the phthalates content in textiles based on the user's determination accuracy requirements, thereby improving the intelligence level of the determination of phthalates in textiles.

[0070] Embodiment 2:

[0071] This embodiment provides a device for determining phthalates in textiles, such as Figure 1 As shown, it includes at least one data processing center 1 and at least two different types of phthalate determination equipment. The data processing center 1 is used to obtain basic demand data of users, obtain basic demand characteristics according to the basic demand data, and calculate the phthalate determination accuracy preference according to the basic demand characteristics, control the action of the phthalate determination equipment that matches the phthalate determination accuracy preference, and realize the determination of phthalates in the textile to be tested.

[0072] Wherein, the phthalate determination device is used to achieve the determination of phthalates in textiles. Preferably, the at least two different types of phthalate determination devices include a first determination device for determining phthalates based on a biological method and a second determination device for determining phthalates based on a chemical method.

[0073] The first determination device is based on the biological method for determining phthalates, and is configured to quickly determine whether the textile to be tested contains phthalates, and to roughly determine the phthalate content in the textile to be tested. The second determination device is based on the chemical method for determining phthalates, and is configured to accurately determine the phthalate content in the textile to be tested, for example, the phthalate content in the textile to be tested can be determined by a gas chromatography-mass spectrometry instrument or a liquid chromatography-mass spectrometry instrument with high sensitivity and accuracy.

[0074] In short, the first measuring device is suitable for occasions where the measurement accuracy of phthalates is not required to be high, and the second measuring device is suitable for occasions where the measurement accuracy of phthalates is required to be high.

[0075] Preferably, the data processing center 1 and at least two different types of phthalate determination equipment are installed together, and the phthalate determination equipment is connected to the data processing center 1 in communication. At least two different types of phthalate determination equipment are configured to automatically determine the phthalate content in the textile to be tested according to the control instructions of the data processing center 1. That is to say, the phthalate determination equipment is a fully automatic phthalate content determination equipment, including the most basic textile pretreatment components to be tested (such as crushing, weighing, dissolving in water samples, etc.) and the phthalate content determination components of the textile to be tested after pretreatment (such as gas chromatography-mass spectrometer 2). Since the equipment for fully automatic measurement of the phthalate content of textiles based on biological methods or chemical methods belongs to the conventional technical means in this field, it is not repeated here.

[0076] The basic demand data refers to information data associated with the preference for phthalate determination accuracy, including but not limited to the user's identity information, the type of textile to be tested, past measurement accuracy requirements, etc. The user's identity information is associated with his or her identity and occupation, which can reflect his or her preference for the measurement accuracy of phthalates in textiles to a certain extent. The type of textile to be tested and past measurement accuracy requirements are also closely related to the measurement accuracy of phthalates in textiles.

[0077] The phthalate measurement accuracy preference is calculated according to the basic demand characteristics, and the actual measurement accuracy requirement of the user can be obtained. Therefore, based on the calculated phthalate measurement accuracy preference, the action of the phthalate measurement device that matches the phthalate measurement accuracy preference is controlled, and the matching phthalate measurement device can be automatically selected according to the different measurement accuracy requirements of the user for the phthalate content in the textile.

[0078] Preferably, the measurement accuracy of at least two different types of phthalate determination devices is different. The device for determining phthalates in textiles also includes a user terminal bound to a user identity. Before controlling the action of the phthalate determination device that matches the phthalate determination accuracy preference to achieve the determination of phthalates in the textile to be measured, the data processing center 1 first sends the calculated phthalate determination accuracy preference and the relevant information of the selected matching phthalate determination device such as type, parameters, measurement time, measurement fee, etc. to the user terminal. After receiving the confirmation instruction fed back by the user terminal or after exceeding the preset waiting time without receiving the feedback from the user terminal, the data processing center 1 controls the action of the phthalate determination device that matches the phthalate determination accuracy preference to achieve the determination of phthalates in the textile to be measured. If there is a phthalate determination device of the user specified type in the feedback information of the user terminal received by the data processing center 1, the action of the phthalate determination device of the user specified type is controlled to automatically achieve the determination of the phthalate content in the textile. In this way, by setting a user terminal, the action of the phthalate determination device that matches the phthalate determination accuracy preference is controlled, so that before the phthalate in the textile to be measured is measured, the user's feedback information is first obtained, and the phthalate content in the textile is measured based on the feedback information. On the one hand, the intelligence level of the entire phthalate determination device in the textile is improved, and on the other hand, the matching phthalate determination device can be automatically selected according to the different measurement accuracy requirements of the user for the phthalate content in the textile.

[0079] In summary, the device for determining phthalates in textiles calculates the user's preference for phthalates determination accuracy and selects a matching phthalates determination device. It can automatically complete the determination of the phthalates content in textiles based on the user's determination accuracy requirements, thereby improving the intelligence level of the determination of phthalates in textiles.

[0080] like Figure 2 As shown, in this embodiment, the first determination device for determining phthalates based on the biological method includes at least one detection pool 4, an oxygenation mechanism 5, a dissolved oxygen measurement mechanism 6 and a biological detection mechanism (not shown in the figure).

[0081] The detection pool 4 stores water, which can be arranged in parallel, preferably in multiple numbers, to meet the needs of multiple different users for the content of phthalates in textiles at the same time, that is, to measure the content of phthalates in multiple textiles at the same time.

[0082] The oxygenation mechanism 5 is used to add oxygen to the water body according to the oxygenation instruction to adjust the dissolved oxygen content of the water body, and includes an oxygenation pump and a shunt pipe, and the oxygenation pump and the shunt pipe are connected through a soft air pipe. Since the determination of phthalates is based on the biological method, the degrading bacteria 10 will consume the dissolved oxygen in the water body when reacting aerobically with phthalates. Therefore, by setting the oxygenation mechanism 5, the detection pool 4 can be reused to determine the phthalate content of textiles.

[0083] In addition, if the dissolved oxygen content in the water body is too low and the phthalate content in the textile is too high, the phthalate content in the textile to be tested is measured by the dissolved oxygen consumed by the degrading bacteria 10 in the aerobic reaction with the phthalate, and there will be a problem that the measurement accuracy error is large or even the phthalate content in the textile cannot be roughly measured. By increasing the dissolved oxygen content of the water body by the oxygenation mechanism 5, the dissolved oxygen content of the water body can also be enriched, avoiding the problem that the degrading bacteria 10 cannot effectively react with the phthalate in the aerobic reaction due to insufficient dissolved oxygen content in the water body, and then the measurement accuracy error is large or even the phthalate content in the textile cannot be roughly measured.

[0084] The dissolved oxygen measuring mechanism 6 is used to measure the dissolved oxygen content of the water body and feed it back to the data processing center 1. Figure 5 As shown, the biological detection mechanism includes a terminal 7 and a microfiltration membrane 8 covering the terminal 7, wherein the microfiltration membrane 8 stores degradation bacteria 10 that can react aerobically with phthalates. When measuring the phthalate content in the textile, the terminal 7 at least partially extends into the water body and the degradation bacteria 10 in the microfiltration membrane 8 of the terminal 7 are in contact with the water body.

[0085] The data processing center 1 obtains the dissolved oxygen content in the water body and compares the consumption value of dissolved oxygen in the water body before and after the end 7 is inserted into the water body, thereby determining the phthalate content in the textile and feeding it back to the user terminal.

[0086] Preferably, the microfiltration membrane 8 is sleeved on the probe through an elastic collar 9, and the degradation bacteria 10 is in contact with the probe to facilitate replacement of the degradation bacteria 10. Since the degradation bacteria 10 that can react aerobically with phthalates are conventional technical means in the art, they are not described here.

[0087] Preferably, the data processing center 1 stores data related to the degradation of phthalates by the degradation bacteria 10 that react aerobically with phthalates, and the data includes a curve function between the consumption value of dissolved oxygen and the content of phthalates in the textile. Based on the curve function, the data processing center 1 determines the content of phthalates in the textile according to the actual consumption value of dissolved oxygen in the water body.

[0088] It should be noted that the first determination device for determining phthalates based on the biological method at least includes a first driving mechanism that is controlled by the data processing center 1 and can respond to the control instructions of the data processing center 1 to control the oxygenation mechanism 5 to add oxygen to the water body and adjust the dissolved oxygen content of the water body, and a second driving mechanism that controls the biological detection mechanism to extend into or withdraw from the water body of the detection pool 4. Since the first driving mechanism and the second driving mechanism belong to conventional technical means in the field, they are not described here in detail.

[0089] In this embodiment, if Figure 3 As shown, the second measuring device for measuring phthalate esters based on a chemical method includes a pre-processing mechanism 3 and a gas chromatograph-mass spectrometer 2 .

[0090] The pretreatment mechanism 3 is used to pretreatment the textile to be tested. Specifically, the pretreatment mechanism 3 includes a crushing unit, a weighing unit, an extraction unit and a filtering unit.

[0091] The crushing unit is used to crush the textile to be tested; the weighing unit is used to weigh the textile to be tested after the crushing process; the extraction unit is used to dissolve and extract the textile to be tested after the crushing process; and the filtering unit is used to filter and evolve the textile to be tested after the dissolution and extraction process.

[0092] The gas chromatograph mass spectrometer 2 is used to determine the content of phthalates in the pretreated textile to be tested.

[0093] Since the pretreatment mechanism 3 and the gas chromatograph-mass spectrometer 2 are conventional technical means in the art, they will not be described in detail here.

[0094] This embodiment also provides a method for using a device for determining phthalates in textiles, such as Figure 4 As shown, it includes the following steps:

[0095] S1, obtain the user's basic demand data.

[0096] S2: Obtain basic demand characteristics according to the basic demand data.

[0097] S3, calculating the phthalate determination accuracy preference according to the basic demand characteristics.

[0098] S4, selecting a matching phthalate determination device based on the phthalate determination accuracy preference.

[0099] S5, determining the phthalates in the textile to be tested by using the selected phthalate determination equipment.

[0100] Preferably, in step S5, the specific method for determining phthalates in the textile to be tested by the selected phthalate determination device comprises the following steps:

[0101] S51, determining the type of the selected phthalate measuring device.

[0102] S52, if the selected phthalate determination device is the first determination device based on the biological method for determining phthalates, the textile to be tested is treated and dissolved in the water of the detection pool 4, and steps S53-S55 are executed. If the selected phthalate determination device is the second determination device based on the chemical method for determining phthalates, the textile to be tested is pretreated and step S6 is executed.

[0103] S53, placing at least a portion of the tip 7 of the biological detection mechanism in a body of water.

[0104] S54, measuring the change value of the dissolved oxygen content of the water body through the dissolved oxygen measuring mechanism 6.

[0105] S55, determining the content of phthalates in the textile to be tested according to the change value of the dissolved oxygen content in the body.

[0106] S56, measuring the content of phthalates in the pretreated textile by means of a gas chromatograph-mass spectrometer 2.

[0107] Specifically, the specific method for pre-treating the textile to be tested includes the following steps:

[0108] Crushing the textile to be tested;

[0109] Weighing the textile to be tested after the crushing process;

[0110] Performing dissolution and extraction treatment on the textile to be tested after the crushing treatment;

[0111] The textiles to be tested after the dissolution and extraction treatment are subjected to filtration and evolution treatment.

[0112] Since pre-treatment of the textile to be tested is a conventional technical means in the art, it will not be described in detail here.

[0113] The method for using the device for determining phthalates in textiles can automatically determine the phthalates content in textiles based on the user's determination accuracy requirements by calculating the user's phthalates determination accuracy preference and selecting a matching phthalates determination device, thereby improving the intelligence level of the determination of phthalates in textiles.

[0114] Embodiment three:

[0115] It should be understood that this embodiment at least includes all the technical features of the above embodiments, and is further described in detail based on the above embodiments.

[0116] In this embodiment, the basic demand data refers to information data associated with the phthalate measurement accuracy preference, including but not limited to the user's identity information, the type of textile to be tested, past measurement accuracy requirements, etc. The user's identity information is associated with his or her identity and occupation, which can reflect his or her preference for the measurement accuracy of phthalates in textiles to a certain extent. The type of textile to be tested and past measurement accuracy requirements are also closely related to the measurement accuracy of phthalates in textiles.

[0117] Different measurement accuracy preference weights may be assigned to different basic demand characteristics, such as different measurement accuracy preference weights may be assigned to different identities and occupations. The type of textile to be tested is preferably the product type corresponding to the textile to be tested.

[0118] The phthalate determination accuracy preference Among them, R i represents the measurement accuracy preference weight corresponding to the i-th basic requirement feature, which can be set by technicians based on experience, β i The adjustment coefficient representing the measurement accuracy preference weight corresponding to the i-th basic requirement feature is set by the technical staff. It represents the average value of the past measurement accuracy requirements, and n represents the total number of types of basic requirement characteristics.

[0119] For the average value of past measurement accuracy requirements, if the data processing center does not store the user's past measurement accuracy requirements, then R his Preferably, if the data processing center does not store the user's past measurement accuracy requirements, the type of textile to be tested is first determined, and then the past measurement accuracy requirements of the same type of textile for different users are obtained, and finally the average of the past measurement accuracy requirements of the same type of textile for different users is used as In this way, the average value of the past measurement accuracy requirements of different users for the same type of textiles is used as the past measurement accuracy requirements of the textiles to be tested. Combined with big data technology, the past measurement accuracy requirements of different users are taken into account to calculate the phthalate measurement accuracy preference, which can better meet the user's actual measurement accuracy requirements.

[0120] By formula By calculating the preference for phthalate determination accuracy and taking into account the measurement accuracy weights corresponding to different basic demand characteristics, users' requirements for the measurement accuracy of phthalate content in textiles can be better obtained, so as to complete the determination of phthalate content in textiles, thereby meeting the measurement accuracy requirements of different users and improving the intelligence level of phthalate determination in textiles.

[0121] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0122] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
