Embodiment 1

[0058] Such as Figure 1 to Figure 4 As shown, a device for controlling signal on-off includes a control terminal 100, a test terminal 200 electrically connected to the control terminal 100, a power supply terminal 500, a communication and monitoring terminal 600, an interactive terminal 700, and an alarm terminal 800, wherein the test terminal The input end of 200 is electrically connected to the output end of equipment end 400, the output end of test end 200 is electrically connected to the input end of vehicle end 300, the communication and monitoring end 600 is respectively electrically connected to vehicle end 300 and remote end 900, and the test The terminal 200 is composed of a plurality of switch 201 (such as the first switch, the second switch...the nth switch), and the device terminal 400 is composed of various external devices (such as the first device, the second device...the nth switch) n devices), each circuit breaker 201 can reproduce the fault of the correspond...

Embodiment 2

[0082] Such as Figure 5 As shown, a method for controlling signal on-off, using a device for controlling signal on-off in Embodiment 1, is performed according to the following steps:

[0083] Step 1, set the test conditions (that is, the reproduction conditions):

[0084] The first channel switch (referring to electronic switch or mechanical switch) is turned on and maintained for Ton1, and off and maintained for Toff1;

[0085] The second channel switch (referring to electronic switch or mechanical switch) is turned on and maintained for Ton2, and off and maintained for Toff2;

 …

[0086] The nth channel switch (referring to the electronic switch or mechanical switch) is turned on and maintained for TonN, and the off and maintained time is ToffN;

[0087] The connection method is single connection or a preset combination of certain channels is connected simultaneously or all channels are connected at the same time; (the connection method is set according to different spe...

Embodiment 3

[0101] In this embodiment, the steps of the method for switching on and off the control signal of channel 1 are as follows:

[0102] Step 1, set the recurrence condition:

[0103] Set the on-hold time of the circuit breaker 1 as Ton1=100ms (this time can be the same every time, or change gradually every time), and the hold-off time Toff1=100ms (this time can be the same every time, or change gradually every time) ;

[0104] Step 2, set the fault phenomenon:

[0105] The vehicle-machine interface in channel 1 (referring to the 301 display screen of the vehicle under test) is not switched to a specific interface within the specified time;

[0106] Step 3, execute the test:

[0107] Channel 1 is connected to an external U disk, and the test of channel 1 is carried out according to the setting time of step 1;

[0108] Step 4: Determine whether channel 1 of the vehicle under test 301 is not switched to a specific interface when the on-hold time is Ton1=100ms and the off-hold ti...

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a device and method for controlling signal on-off. Background technique [0002] There are more and more functions integrated in the car machine (referring to automotive electronic products), resulting in more and more signals input and output to the car machine. Input signals such as camera video signals (differential, coaxial, etc.), USB signals, Ethernet signals, microphone signals, vehicle speed signals, reversing signals, handbrake signals, RF, power and other signals; output signals such as video signals (differential, coaxial, etc.) axis, etc.), Ethernet signal, USB and other signals. In order to test whether these input and output signals are in the process of repeated interruptions, whether the functions of the vehicle are operating normally, the usual method is to manually plug and unplug these signal interfaces to simulate these signal interruptions, es...
