Abstract

The embodiment of the present invention provides a control device and method for controlling power on and off of a sample. The control device for controlling power on and off of a sample includes: a power supply, a first voltage dividing resistor, a second voltage dividing resistor, a first thermistor, a second thermal Thermistor and temperature control switch; the positive pole and negative pole of the power supply are respectively connected to the positive pole and negative pole of the control sample, the control sample is in the temperature box, the first thermistor and the second thermistor are pasted on the shell of the control sample, The temperature control switch is in the temperature box; the first voltage dividing resistor and the second voltage dividing resistor are connected in series to the positive pole and the negative pole of the power supply; the first thermistor and the temperature control switch are connected in series to both ends of the first voltage dividing resistor; The second thermistor is connected to both ends of the second voltage dividing resistor; the connection point between the temperature control switch and the second thermistor is connected to the power-on switch of the control sample. In this embodiment, the power-on and power-on control of the control sample is realized through the thermistor and the temperature control switch, with simple logic, low cost, and more precise control of power-on time.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle testing, and in particular to a control device and method for controlling power on and off of a sample. Background technique [0002] In order to make the vehicle reach the best running state, it is necessary to conduct a reliability test on the vehicle controller, that is, conduct a high-temperature and low-temperature functional test on the vehicle controller (hereinafter referred to as "control sample"). [0003] At present, the existing test method commonly used is that the temperature box is connected to the host computer through the network cable at the same time, and the host computer controls the power supply to power on and off the sample according to the temperature fed back by the temperature box. [0004] This method is expensive, complex logic, and because the temperature uploaded by the thermostat is not the temperature of the controller itself, the control ...
