Abstract: This invention discloses a temperature-measuring scan head, comprising an enclosure, and its use method. There are supplementary lamp, image sensor and temperature sensor embedded on the end surface of the enclosure. 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. Technically, the operator should use the scan head to scan the barcode of the objects or living things to be measured, and the scan head will read identity information and conduct temperature measurement. As such, temperature of the objects or living things corresponds to their respective identity, thereby guaranteeing the accuracy of data.

Abstract: The invention discloses a scan head's aiming beam exposure solution system, comprising the control circuit of aiming lamp. The control circuit is composed of 5 pin terminals, wherein pin 1 and 2 are the input terminal of gate circuit, and pin 4 is the output terminal of NOT gate circuit; the high level Vcc is connected with pin 5 of the control circuit, and pin 3 of the control circuit is grounded; the pin 1 and 2 are connected with the scanning signal and the field sync signal respectively, and resistor R1 is connected with the field sync signal and is grounded. The solution system, compared with the existing scan heads on the market, can completely solve the local overexposure problem of the aiming beam, hugely improve the decoding accuracy, stability, identification rate, decoding speed and power consumption of the scan head hugely, and realize cost-effectiveness easily.
