Abstract

The invention discloses a cold zone target range intersection measurement system temperature control module comprising a master chip (U1), a MOS transistor (Q1), three resistors (R1, R2, R3), a heating sheet (J1), a thermistor (R4) and a heating film (P1). The signal positive end of the master chip (U1) is connected with a signal receiving end through the second resistor (R2). The gate electrode of the MOS transistor (Q1) is connected with the collection electrode of the master chip (U1). The gate electrode of the MOS transistor (Q1) is also connected with a 12V power supply through the first resistor (R1), and the drain electrode of the MOS transistor (Q1) is connected with the second port of the heating film (P1). One end of the heating sheet (J1) is connected with the negative electrode of the heating film (P1), and the other end is connected with the positive electrodes of the heating film (P1). The two positive electrodes of the heating film (P1) are connected with the 12V power supply. One end of the thermistor (R4) is connected with the negative electrode of the heating film (P1), and the other end is connected with the positive electrodes of the heating film (P1). The positive electrodes of the heating film (P1) are connected with a 3.3V power supply. The temperature control module is high in sensitivity and easy and convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of temperature control of optical measuring equipment, in particular to a high-sensitivity, high-efficiency and easy-to-operate temperature control module of a frigid shooting range intersection measurement system. Background technique [0002] Intersection measurement is a kind of optical measurement technology. It is a non-contact measurement technology developed rapidly in recent years. It has the advantages of convenient use, high measurement accuracy, strong real-time performance and high degree of automation. [0003] For the intersection measurement system, it is necessary to consider its application environment, use conditions, detection accuracy, etc. In terms of hardware, in order to cover the field of view as much as possible and adapt to more shooting environments, two cameras with high frame rate and high resolution can be selected. The turntable (theodolite is often used instead of the turntab...
