after the mainboard is powered on to operate, if the programmable logic controller can receive five continuous groups of pulse signals within a preset time period, the qualified lamp flickers to prompt that the mainboard is qualified; otherwise, the buzzer alarms to prompt that the mainboard is unqualified; and the COM-ZJ communication port transmits five groups of communication signals in a preset time period.
10. The detection method according to claim 9, wherein the step of transmitting the communication signal to a signal converter by the mainboard detection tool comprises: the mainboard detection tool receives a communication signal from the mainboard through a probe of the bracket, wherein the probe is connected with the COM-ZJ communication port; the mainboard detection tool transmits the communication signal to the signal converter through a tool converter connecting wire.
11. The method of claim 9, wherein the signal converter converting the communication signal into a pulse signal to be transmitted to a programmable logic controller comprises: the signal converter converts and amplifies the communication signal into a pulse signal; and the signal converter transmits the pulse signal to the programmable logic controller through a converter controller connecting wire.
12. The method according to claim 9, wherein the step of receiving a power signal from the motherboard testing tool by the plc to record a motherboard power-on running time comprises: the mainboard detection tool transmits the power signal to the programmable logic controller through a connecting wire of a tool controller so that the programmable logic controller can record the power-on running time of the mainboard.
