Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It should be noted that "trace elements" as referred to herein include: lead, cadmium, copper, zinc, iron, calcium, and magnesium; the sample to be detected is animal tissue or plant resistance, and further the trace element detection method in the embodiment can be suitable for different industrial technical fields, the actual content of the trace elements in the sample to be detected is automatically and accurately detected, so that various control requirements of a user are met, the sample to be detected is subjected to real-time state detection, and good use experience is brought to the user.
Referring to fig. 1, a specific implementation flow of the trace element detection method provided in the embodiment of the present application accurately detects the actual content of the internal trace element in the sample to be detected, so as to meet the actual content detection requirement of the user; for convenience of explanation, only the parts related to the present embodiment are shown, and detailed as follows:
the trace element detection method comprises the following steps:
step S101: and carrying out reaction detection on the sample to be detected positioned at the detection position and obtaining a detection result.
The detection position is a preset sample detection position, the sample to be detected is placed at the detection position, and reaction detection is carried out on the sample to be detected so as to analyze the internal component information of the sample to be detected and obtain a detection result. Starting a chemical, physical or biological reaction detection process for a sample to be detected, and further analyzing the internal composition information of the sample to be detected; when the reaction detection is carried out on the sample to be detected, the rapid and efficient detection function of the content of each trace element in the sample to be detected is completed; the automatic and accurate detection function of the trace elements in the sample to be detected is realized, and the detection steps of the trace elements in the sample to be detected are simplified.
Step S102: and acquiring an element detection request instruction, and determining a target detection element requiring detection according to the element detection request instruction.
Optionally, the element detection request instruction may be input by a user on the detection device, input by an external control terminal, or preset by the detection device, for example, the trace element detection process is controlled in real time through the user input. The element detection request instruction comprises target element selection information, and after the element detection request instruction is analyzed and identified, one trace element can be selected as a target detection element from a plurality of to-be-controlled trace elements, for example, iron is used as the target detection element, so that the detection step of the content of iron in the to-be-detected sample is started.
Therefore, the embodiment can select the target detection element required to be detected by the user according to the actual detection requirements of the user on various elements, and complete the detection process of the actual content of the target detection element, and the trace element detection process has high controllability and brings good use experience to the user.
Step S103: and acquiring the content of the target detection element in the sample to be detected from the detection result, and outputting the content detection result in a preset mode.
The target detection element is used as one of multiple trace elements, and the content of the target detection element in a sample to be detected can be obtained after analysis of a detection result, so that the function of accurately detecting the actual content of the target detection element is realized. And after the content of the target detection element is detected, the content detection result can be output in a preset mode, such as direct display, sending to a client or a server by data packet information, and the like, so as to meet various requirements.
When the content of the trace elements is detected and displayed in real time, a user can conveniently and rapidly obtain the actual content of the target detection elements in the sample to be detected. Therefore, the embodiment not only can accurately and efficiently detect the actual content of the trace elements, but also can provide a content detection result, bring good use experience to users, and improve the application range of the trace element detection method.
As an alternative implementation manner, fig. 2 shows another implementation flow of the trace element detection method provided in this embodiment, and compared with the implementation flow of the trace element detection method in fig. 1, before performing reaction detection on a sample to be detected located at a detection position and obtaining a detection result, the trace element detection method further includes:
step S201: and acquiring the identity information of the user and verifying whether the user is a legal visitor.
Optionally, the identity information of the user is obtained, and the difference between the identity information of the user and the preset identity information is compared to verify whether the user is a legal visitor. For example, the identity information of the user includes a user name and a user password, where the preset identity information is a name and a password stored in advance. By verifying the identity information of the user, whether the user has the control authority of the trace element detection process can be identified, and the safety and the reliability of the trace element detection method are further guaranteed. Illustratively, when the user name is the same as the pre-stored name and the user password is the same as the pre-stored password, it is indicated that the user belongs to a legitimate visitor. Therefore, the embodiment can avoid the trace element detection by illegal visitors by identifying the identity information of the user.
Step S202: and when the user is judged to be a legal visitor and a control instruction for obtaining the sample to be detected is received, obtaining the sample to be detected according to the control instruction.
When the user is a legal visitor, optionally, the sample to be detected is associated with the user, and the sample to be detected associated with the user is obtained according to the control instruction so as to meet the element detection requirement of the user. In another embodiment, the user is used as an experimenter, and then the sample to be detected specified by the control command is obtained according to the control command to perform the next reaction detection. For the acquisition of the sample to be detected, the sample to be detected to be subjected to the reaction detection may be manually placed at the detection position, or the sample to be detected to be subjected to the reaction detection may be grabbed from the sample library by the manipulator, or even the sample to be detected to be subjected to the reaction detection may be marked in the sample library to be subjected to the reaction detection in the next step.
