The application mode of the non-contact wrist pulse position temperature acquisition equipment provided by the invention is as follows: the device is placed at the entrance of a public place or in the public place, when the body temperature needs to be measured, the camera acquires the height information of the human body, so that the height of the temperature measuring device 6 is adjusted through the sliding block. The measured person places a certain part of the arm under the temperature measuring device 6, the temperature measuring device 6 measures the body temperature of the person, if the body temperature is normal, the temperature measuring frame 5 is lifted to be released, and if the body temperature is abnormal, an alarm signal is sent to inform the staff of further processing.
The reason for measuring the arm temperature is that: the arm of the human body is a part covered by clothes, such as a palm, a wrist, a forearm and the like, and the temperature of the arm is not influenced by the environment (or is little influenced by the environment), so that the real temperature of the human body can be reflected by the measuring arm more accurately. During measurement, the person to be measured is required to roll up the sleeves, preferably the wrist.
The non-contact wrist pulse position temperature measurement method using the device comprises the following steps:
Step S1, when a person is detected to approach the equipment, the voice prompt person places the wrist below the temperature measuring device, the temperature measuring device senses temperature jump of the wrist, temperature information is acquired, skin temperature of a wrist pulse area of the person to be measured is obtained, and meanwhile an environmental temperature detection sensor of the temperature measuring device measures environmental temperature;
S2, judging whether the wrist skin temperature value of the personnel is greater than an effective threshold value, if so, recording measurement data, and if not, returning to the step S1 for re-measurement;
s3, judging whether the effective duration of the measured temperature is greater than a duration threshold value, if so, going to the next step, and if not, returning to the step S1 for re-measurement;
s4, calculating the body temperature of the person to be measured by combining the ambient temperature;
The formula for calculating the actual body temperature of the measured person is as follows:
T＝AxTw+BxTa+C,
wherein: t is body temperature, T w is wrist temperature, T a is ambient temperature, and A, B, C is a parameter.
Preferably, the parameters range from: a epsilon [0.15,0.2], B epsilon [ -0.055, -0.035], C epsilon [28,32].
And S5, comparing the calculated body temperature with a threshold value, if the measured body temperature is smaller than the upper limit of the normal body temperature of the human body, considering the body temperature to be normal, entering the next step, and when the measured body temperature exceeds the threshold value, turning on a red indicator lamp, giving an alarm by a buzzer and notifying on-site staff.
When the equipment is applied to the entrance of a building, the initial position is that the arm is retracted, after the power is on, the robot enters a standby state, after a temperature measurement starting button is pressed, the robot is lighted by a red light, and the robot enters a working state, and meanwhile, the arm extends out to stop a person outside a door and prevent the person from passing. In the step S5, when the body temperature of the tested person is normal, the tested person is released; and when the body temperature of the tested person exceeds the threshold value, the test is not released.
The release mode is as follows: the sliding block drives the temperature measuring rack to move upwards, and an inlet channel is reserved for releasing.
When the device is applied as an autonomous temperature measuring device, for example, inside a hospital triage or other building, the following steps may also be included:
And S6, printing a temperature measurement result, detecting and confirming that the personnel leave by the equipment, and recovering the initial position. The machine can also count the total number of people, the qualified number of people and the unqualified number of people with temperature measured in the whole day, count the number of people with the day as a period, and store the information of the number of people in a month according to the daily statistical information or according to the time period actually needed.

Unlike the first embodiment, the intermediate rod 9 of the temperature measuring rack in this embodiment can be extended and contracted as shown in fig. 2. The telescopic middle rod has the beneficial effects that:
Firstly, the requirements of different inlet widths are met, and when the inlet is narrow, a part of the inlet can be contracted; when the inlet is wide, a portion may protrude.
Secondly, when the equipment is not used, the middle rod can be contracted, so that the storage volume of the equipment is reduced.
Thirdly, when the body temperature is detected to be qualified, the person passes through the entrance by contracting the middle rod. Therefore, the non-contact wrist pulse position temperature acquisition equipment of the second embodiment has two release modes, namely, the temperature measuring rack is lifted or the temperature measuring rack is retracted.
The telescopic mode of the middle rod can adopt the telescopic mode of the prior art, and only the strength of supporting the temperature measuring device can be met. For example, the intermediate rod shown in fig. 2 is composed of shells of different sizes, all of which are sleeved one by one according to the size, and when retracted, the intermediate rod is sleeved in the adjacent larger shells in sequence, and when required to be lengthened, the intermediate rod is extended.
