Embodiment 1

[0062] The workflow of the control device for powering on the RTM provided by the present invention is as follows:

[0063] The power input to the connector is 12V_IN. When the RTM is plugged in, make sure that the power supply is connected to the signal line before starting to operate.

[0064] First of all, during the insertion of the rear module RTM, the signal line and power line will be connected first. If the power line is connected first, since the rear module RTM does not provide power, the signal line will not have any action and will not affect the Front board (system main board) )Work.

[0065] After a certain power line of the rear plug-in module RTM is connected, if the power is turned on immediately, a large amount of current will flow through this pin and cause system damage. Therefore, the control device for powering on and off the RTM needs a hot-swappable controller, which is realized by the control chip TPS2490. Only when the enable signal EN of the contro...

Abstract

The invention relates to a rear-end transfer module (RTM) electrifying control device. The device comprises a micro switch SW1, a power controller Q13, a power controller Q14, a capacitor C279 and a hot plug controller, wherein the micro switch SW1 is used for controlling a power supply 12V-IN; the power controller Q13 is used for reversing a closing signal of the micro switch SW1; the power controller Q14 generates a falling edge and is used for informing a back interpolation module RTM of electrifying; the capacitor C279 prevents the power supply 12V-IN from raising to an opening threshold of the hot plug controller and prevents an excessive current from flowing into the RTM electrifying control device so as not to cause damage; the power supply 12V-IN electrifies the device; a power supply 12V-EN supplies power to the power controller Q13; and the micro switch SW1, the power controllers Q13 and Q14, the capacitor C279, the hot plug controller and the power supplies 12V-IN and 12V-EN are welded on the back interpolation module RTM. The device is simple in structure, the cost is saved, the RTM can be well controlled to electrify, and the influence of an unstable power supply is avoided.

Description

technical field [0001] The present invention relates to a control device, in particular to a control device for powering on an RTM (Rear Transition Module). Background technique [0002] Due to cost considerations, the same connector is used for the power supply and the signal, which may cause the power supply to not be completely stable when the signal line is connected, and will affect the Front Board (the main board of the system, located in the front half of the chassis, to achieve the main exchange and calculation. function) have adverse effects on the working status. In order to eliminate this problem, we have designed a special power supply control system. When the module is inserted, the system will not be powered on immediately, but wait for the installation handle to be inserted into a specific position. Before that, all the signals of the connector have been ensured. up. The RTM system will only start to power up when the handle is locked into a specific positio...
