The invention relates to technical field of computer. To be specific, it includes a temperature-measuring scan head and its use method.
As mobile internet and its terminals are developing flourishingly, scan decoding technology is widely used in various industries, including logistics, retail, warehousing, medical service and livestock raising. However, some shortcomings of the existing scan heads are exposed.
Among the current 2D scan head schemes, all of them provide very simple functions, namely, to decode one-dimensional or two-dimensional barcodes only. As mobile IoT technologies are deeply explored in various industries, customers have high requirements on the existing scan heads. That includes not only improved working speed and stability, but also functional diversity. For example, current body temperature of a patient should be measured in medical industry. This refers to temperature of animals in animal husbandry so as to prevent diseases. Even for fire prevention of warehouse, overheat of equipment, and cold-chain storage and transportation, temperature information is necessary. However, the existing scan heads are unable to meet this function.
This invention is to provide a temperature-measuring scan head and its use method. Except for decoding one-dimensional and two-dimensional barcodes that the existing scan heads do, the present scan head is able to measure temperature with precision. That helps match temperature of the measured objects or human things with their respective identity. It solves the problem mentioned against the background aforesaid.
In order to achieve the purpose aforesaid, the invention presents a technical proposal as follows: a temperature-measuring scan head, comprising an enclosure. The enclosure has supplementary lamp, image sensor and temperature sensor at its end face. There are 2 groups of the supplementary lamps, each being installed at the ends of the enclosure. Between these two groups are the image sensor and the temperature sensor arranged in order. The terminals of both image sensor and temperature sensor are electrically connected to the central processing unit via wires. The supplementary lamp, image sensor and temperature sensor are electrically provided with control switch.
The steps of using the present temperature-measuring scan head are given below:
Step 1: Turn on supplementary lamp and image sensor via the control switch;
Step 2: Align the present scan head with barcode of objects or living things to be measured;
Step 3: Turn off image sensor and then supplementary lamp via the control switch;
Step 4: Turn on temperature sensor via the control switch;
Step 5: Collect and process data via the central processing unit, and send data to the upper computer for saving.
In the Step 5 above, the upper computer is a computer that is electronically connected to the present scan head via wires, and the central processing unit is inside the computer.
Preferably, the supplementary lamp, image sensor and temperature sensor are all controlled by control switch on which there are three groups of buttons that control the working status of supplementary lamp, image sensor and temperature sensor respectively.
Preferably, there is a temperature-calibration module inside the temperature sensor.
Compared with the existing technologies, the present invention stands out for the temperature-measuring scan head and its use method. The present scan head is as small as the existing scan heads on the market, but it has high-precision temperature sensor with built-in temperature-calibration module that promises temperature information collection and accurate temperature measurement. Therefore, the application of the present temperature-measuring scan head is employed in a wider range of industries. Current body temperature of a patient should be measured in medical industry. This refers to temperature of animals in animal husbandry so as to prevent diseases. Even for fire prevention of warehouse, overheat of equipment, cold-chain storage and transportation, temperature information is necessary. The present scan head can do this. Technically, the operator should use the present scan head to scan the barcode of the measured objects or living things, and the present scan head will read identity information and conduct temperature measurement. As such, temperature of the measured objects or living things corresponds to their respective identity, thereby guaranteeing the accuracy of data.
This part, in line with the drawings included in the embodiments of the invention, describes the technical proposal of the invention in detail and completely. Obviously, the embodiments described herein are not exhaustive. Based on the embodiments of the invention, all others that are made by ordinary technicians in the art not creatively shall be subject to the protection of the invention.
With reference to
The steps of using the present temperature-measuring scan head are given below:
Step 1: Turn on supplementary lamp 11 and image sensor 12 via control switch. The former adds lightness when the scan head is scanning barcode of the objects or living things to be measured. That helps obtain an accurate measurement.
Step 2: Align the present scan head with barcode of the objects or living things to be measured. The image sensor 12 is responsible for collecting images and transferring information to the central processing unit which reads the code.
Step 3: Turn off image sensor 12 and then supplementary lamp 11 via the control switch after code access, to make preparations for next temperature measurement. That prevents heat dissipation of the supplementary lamp 11 from affecting the accuracy of data measured by the temperature sensor 13.
Step 4: Turn on temperature sensor 13 via the control switch to measure temperature. That helps match temperature of the measured objects or human things with their respective identity.
Step 5: Collect and process data via the central processing unit, and send data to the upper computer for saving. The upper computer is a computer that is electronically connected to the present scan head via wires, and the central processing unit is inside the computer which can save image and temperature information. All these efforts improve the accuracy of data measured by the present temperature-measuring scan head.
To sum up, the invention covers the present temperature-measuring scan head and its use methods. The present scan head is as small as the existing scan heads on the market, but it has high-precision temperature sensor 13 with built-in temperature-calibration module that promises temperature information collection and accurate temperature measurement. Therefore, the application of the present temperature-measuring scan head is employed in a wider range of industries. Current body temperature of a patient should be measured in medical industry. This refers to temperature of animals in animal husbandry so as to prevent diseases. Even for fire prevention of warehouse, overheat of equipment, and cold-chain storage and transportation, temperature information is necessary. The present scan head can do this. Technically, the operator should use the present scan head to scan the barcode of the measured objects or living things, and the present scan head will read identity information and conduct temperature measurement. As such, temperature of the measured objects or living things corresponds to their respective identity, thereby guaranteeing the accuracy of data.
