Abstract

The embodiment of the invention provides a control sample power-on and power-off control device and method. The control device comprises a power supply, a first divider resistor, a second divider resistor, a first thermistor, a second thermistor and a temperature control switch; a positive electrode and a negative electrode of the power supply are respectively connected to a positive electrode and a negative electrode of a control sample, the control sample is arranged in a temperature box, the first thermistor and the second thermistor are adhered to a shell of the control sample, and the temperature control switch is arranged in the temperature box; the first divider resistor and the second divider resistor are connected in series and then connected to the positive electrode and the negative electrode of the power supply; the first thermistor and the temperature control switch are connected in series and then connected to two ends of the first divider resistor; the second thermistor is connected to two ends of the second divider resistor; and a connection point of the temperature control switch and the second thermistor is connected to a power-on switch of the control sample. Power-on and power-off control over the control sample is achieved through the thermistors and the temperature control switch, logic is simple, cost is low, and control over the power-on moment is more accurate.

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 ...
