Referring to fig. 1 to 2, the present application provides a portable temperature control device for TOF ranging, which is used for verifying ranging performance of a TOF sensor at high and low temperatures, and comprises: a temperature detector for detecting the temperature of the TOF sensor, which is connected with the TOF sensor; a temperature regulator coupled to a TOF sensor for regulating a temperature environment of the TOF sensor, comprising: the temperature control fin is used for heating or refrigerating, and the radiating fin is used for releasing or absorbing heat; and the temperature controller is connected with the temperature detector and the temperature regulator, and outputs a regulating signal according to the temperature detected by the temperature detector to control the temperature regulator.
The temperature regulator comprises a semiconductor refrigeration sheet (Thermoelectric cooler, TEC for short), and the model of the TEC is TEC1-19906. In the embodiment, the TEC selects high-quality TEC (model: TEC 1-19906) with high temperature resistance of 24V and 200 DEG, and the temperature equalizing plate selects long-wide-thick: 100mm x 5mm aluminum alloy profile plate.
The core element of the temperature control of the portable temperature control device is TEC, the TEC can be used for heating and refrigerating, the temperature control of the whole device is realized, when the voltage direction applied by the TEC is positive (red line positive and black line negative), the temperature control sheet refrigerates, and the radiating fin releases heat. When the voltage direction applied by the TEC is negative (red line is negative and black line is positive), the temperature control sheet heats, and the radiating sheet absorbs heat. That is, the voltage direction (i.e. the current direction) is exchangeable, and when the voltage direction is changed, the heat transfer direction is changed, so that the TEC can be used for cooling and also can be used for heating.
The temperature controller comprises a single-channel bi-directional output TEC digital temperature control module, the model is TCM-M115, and Max is 20V/15A.
According to the characteristics of the TEC, the temperature controller selects a temperature controller TCM-M115 with bidirectional output voltage characteristics, namely, the temperature controller can output positive pressure or negative pressure. The output voltage of the temperature controller is calculated according to PID parameters, and the calculation formula of PID is as follows: vout=vin×pid, i.e., the output voltage of the temperature controller is equal to the power supply voltage of the temperature controller multiplied by the calculated result of PID. The PID parameters can be set according to experience or actual test effect adjustment, and the PID parameters can be automatically set by using the self-contained 'automatic setting' function of the temperature controller, so that the overall PID effect is as follows: 1. when PID (proportional coefficient is increased, integral time is reduced, differential time is reduced), response becomes faster, and oscillation becomes larger; 2. decreasing the PID (decreasing the scaling factor, increasing the integration time, increasing the differentiation time) slows down the response and reduces the oscillations.
The portable temperature control device further comprises a temperature equalizing plate, the temperature detector is arranged on the temperature equalizing plate, and the TOF sensor is arranged on the temperature equalizing plate. In this embodiment, the temperature detector includes a temperature probe connected to the temperature equalization plate and the temperature controller.

The radiator is connected with the radiating fin, and the radiating fan is connected with the radiator, specifically, the heat of the radiating fin is conducted to the radiator through the copper pipe of the radiator, and the heat is radiated into the air through the radiating fan.
In this embodiment, the temperature controller communicates with an external computer through an RS232 interface.

When the temperature is raised, the temperature is required to be set at a human-computer interface and is transmitted to a temperature controller through an RS232 interface, the temperature controller receives the real-time temperature measured by a temperature detector, a PID algorithm is combined, the voltage and current output by the temperature controller (the temperature controller outputs negative pressure when the temperature is raised) are calculated, the voltage output by the temperature controller is supplied to a TEC, a heat dissipation surface of the TEC absorbs heat transmitted by a radiator and is transmitted to a temperature control surface of the TEC, the heat is transmitted to a temperature control table through the temperature control surface of the TEC, when the temperature is quickly raised to the set target temperature, the temperature controller calculates and adjusts the output power of the temperature controller according to the temperature value measured by the temperature detector, and the temperature slowly approaches to the target temperature until the temperature value of the temperature control target is stabilized at the target temperature value. The actual temperature control effect test is shown in fig. 2. The portable temperature control device realizes accurate control of-20 degrees to +125 degrees, and well meets the application requirements of TOF ranging products.
The scene when portable temperature control device practical application is, paste TOF range finding product bottom on the samming board to fix TOF range finding product at the samming board with thermal-insulated cotton, only expose TOF range finding product's light transmission path window, then will fix and test on high accuracy guide rail, temperature control device just so can freely acquire the range finding data under the whole range of TOF range finding product according to developer's needs along with the guide rail free movement.
