Referring to fig. 1, an embodiment of the present disclosure provides a power calculating apparatus 100, where the power calculating apparatus 100 includes a power module 110, a slow start circuit 120, a switch circuit 130, a control device 140, a back plate 150, a housing 160, and a power calculating module 170. The power module 110 is used to connect with an external power source to supply power to the force computing equipment 100 and the force computing module 170 therein. The back plate 150 is fixed to the housing 160, and is provided with a connector module 151 adapted to an external device to electrically connect the back plate 150 to the external device, and the force calculating module 170 is detachably connected to the back plate 150 through the connector module 151. One end of the switch circuit 130 is connected to the power module 110, and the other end is connected to the connector module 151, and is connected to the power module 110 through the connector module 151. One end of the slow start circuit 120 is connected to the power module 110, the other end is connected to the switch circuit 130, the control device 140 is electrically connected to the back plate 150, the slow start circuit 120 and the power calculating module 170, and is configured to detect the plugging status of the power calculating module 170 and the connector module 151, and control the switch circuit 130 through the slow start circuit 120 according to the plugging status, so as to power on or power off the power calculating module 170.

The slow start circuit 120, the switch circuit 130, and the control device 140 cooperate together, so that when the power calculation module 170 is inserted into the power calculation apparatus 100, the power supply module 110 slowly starts to power on the power calculation module 170, and when the power calculation module 170 is pulled out from the power calculation apparatus 100, the power calculation module 170 is slowly powered off.

Specifically, when the power calculation apparatus 100 is in the operating state and the control device 140 detects that the power calculation module 170 is plugged into the connector module 151 of the backplane 150, an electrical signal is sent to the slow start circuit 120, and the switch circuit 130 is controlled to be turned on through the slow start circuit 120, so that the power supply module 110 powers on the power calculation module 170 through the switch circuit 130 and the connector module 151, thereby reducing the surge voltage generated by the power calculation apparatus 100 when the power calculation module 170 is plugged. Wherein, the working state refers to a state that the power module 110 normally supplies power to the power module 110 when the power module 170 is plugged with the back plate 150.

Further, when the power calculating device 100 is in the working state and the control device 140 detects that the power calculating module 170 is disconnected from the connector module 151, an electrical signal is sent to the slow start circuit 120, and the switch circuit 130 is controlled to be turned off through the slow start circuit 120, so as to cut off a conduction loop between the power supply module 110 and the power calculating module 170, power is supplied to the power calculating module 170, and surge voltage generated by the power calculating device 100 when the power calculating module 170 is pulled out is reduced.

In some embodiments, the connector module 151 is provided with a triggering connector 1511 electrically connected to the control device 140, the triggering connector 1511 may be a conductive metal, the force calculating module 170 is provided with a triggering connection end 171, and the triggering connector 1511 and the triggering connection end 171 are fittingly inserted to realize the insertion between the force calculating module 170 and the backplate 150. When the control device 140 detects that the trigger connection terminal is properly plugged with the trigger connector, an electrical signal is sent to the slow start circuit 120, and the switch circuit 130 is controlled to be turned on through the slow start circuit 120, so that the power module 110 powers on the power module 170 through the switch circuit 130 and the connector module 151.

Specifically, the control device 140 has an input terminal and an output terminal, the input terminal is electrically connected to the trigger connector, and the output terminal is connected to the input terminal of the slow start circuit 120, so as to input the electrical signal to the slow start circuit 120. Be provided with MCU (Microcontroller Unit) in controlling means 140, controlling means 140 passes through the level state change of MCU monitoring self input to confirm that trigger connector 1511 on backplate 150 and calculate power module 170 on trigger the grafting state of link 171, wherein, the level state of controlling means 140 input includes: a high level state, a low level state, a rising edge state, and a falling edge state, and the matching state between the force calculation module 170 and the back plate 150 is determined by the level state of the input terminal. Wherein, the rising edge state refers to the level value of the input end is converted from low level to high level; the falling edge state refers to a transition of the level value of the input terminal from a high level to a low level.

For example, when the force calculating module 170 is plugged into the back plate 150, the input terminal of the control device 140 is in a high state.

When the force calculating module 170 is separated from the back plate 150, the input terminal of the control device 140 is in a low level state.

When the force calculating module 170 is plugged into the back plate 150, the input end of the control device 140 is in a rising edge state.

When the force calculating module 170 begins to disengage from the back plate 150, the input end of the control device 140 is in a falling edge state.

Therefore, the control device 140 determines the matching state between the power calculating module 170 and the back plate 150 by monitoring the level state change of its input end, so as to control the action of the slow start circuit 120, and start power-up or power-down for the power calculating module 170.

Referring to fig. 2, in some embodiments, the power module 110 includes a first power supply terminal 111, a second power supply terminal 112 and a power input terminal 113. The first power supply terminal 111 is connected to the switch circuit 130 to supply power to the backplane 150 through the switch circuit 130, so that when the force calculation module 170 is mated with the backplane 150, power is supplied to the force calculation module 170 through the backplane. The second power supply terminal 112 is connected to the slow start circuit 120 to be connected to the switch circuit 130 through the slow start circuit 120, so as to control the on/off of the switch circuit 130, and when the switch circuit 130 is turned on, the first power supply terminal 111 is connected to the conductive loop between the connector module 151 on the backplane 150, so that the first power supply terminal 111 can supply power to the power calculating module 170 plugged into the connector module 151. When the switch circuit 130 is turned off, the conductive loop between the first power supply terminal 111 and the connector module 151 is broken, thereby powering down the force calculation module 170. The power input terminal 113 is used for connecting with an external power source, which may be an ac power source or a dc power source, to provide power for the power module 110.

Specifically, when the control device 140 monitors that the force calculation module 170 is plugged into the back plate 150, the control device 140 controls the slow start circuit 120 to start up, so that the conductive loop between the second power supply terminal 112 and the switch circuit 130 is conducted, and the switch circuit 130 is controlled to be closed, so that the first power supply terminal 111 forms a power supply loop with the force calculation module 170 through the switch circuit 130, and the power supply loop is started up slowly for the force calculation module.

Further, when the control device 140 monitors that the force calculation module 170 is detached from the back plate 150, the control device 140 controls the slow start circuit 120 to be turned off, so as to disconnect the conductive loop between the second power supply terminal 112 and the switch circuit 130, thereby controlling the switch circuit 130 to be turned off, so as to disconnect the power supply loop between the first power supply terminal 111 and the force calculation module 170, and to power down the force calculation module slowly.

As shown in fig. 2, in some embodiments, the switch circuit 130 includes a first switch Q1, in this embodiment, the first switch Q1 is an N-channel enhancement mode field effect transistor, a gate of the first switch Q1 is electrically connected to the output terminal of the slow start circuit 120, a source of the first switch Q1 is electrically connected to the first power supply terminal 111, a drain of the first switch Q1 is connected to the connector module 151 to be connected to the power calculating module 170 through the connector module 151, and when the output terminal of the slow start circuit 120 outputs a high voltage to the gate, the first switch Q1 is turned on.

In some embodiments, the number of the first switching tubes Q1 may be multiple, and the gates, the sources and the drains of the multiple first switching tubes Q1 are connected to each other. By arranging the plurality of first switching tubes Q1, the stability of the switching circuit 130 is guaranteed, and meanwhile, the grid current of each first switching tube Q1 is reduced through shunting, so that the effect of protecting the first switching tube Q1 is achieved.

As shown in fig. 2, the slow start circuit 120 includes a second switch Q2 and a third switch Q3, in this embodiment, the second switch Q2 and the third switch Q3 are both N-channel enhancement mode field effect transistors, wherein the gate of the second switch Q2 is connected to the output of the control device 140, the drain of the second switch Q2 is connected to the second power supply terminal 112, and the source of the second switch Q2 is grounded; the gate of the third switching transistor Q3 is connected to the drain of the second switching transistor Q2, the drain of the third switching transistor Q3 is connected to the second power supply terminal 112 and the gate of the first switching transistor Q1, and the source of the third switching transistor Q3 is grounded.

Specifically, when the input electrical signal of the control device 140 changes from low level to high level, the second power supply terminal 112 applies a voltage to the drain of the second switching tube Q2, and the electrical signal acts on the gate of the second switching tube Q2 to make the source and the drain of the second switching tube Q2 conductive, so that the second power supply terminal 112 no longer supplies power to the gate of the third switching tube Q3, and the source and the drain of the third switching tube Q3 are disconnected, so that the power supplied from the second power supply terminal 112 cannot flow through the third switching tube Q3, but acts on the gate of the switching circuit 130.

When the input electrical signal of the control device 140 changes from high level to low level, the electrical signal acts on the gate of the second switching tube Q2 to disconnect the source and drain of the second switching tube Q2, so that the second power supply terminal 112 supplies power to the gate of the third switching tube Q3, and the source and drain of the third switching tube Q3 are connected, so that the power supplied from the second power supply terminal 112 is connected to the voltage zero point via the third switching tube Q3 and cannot act on the gate of the switching circuit 130.

Referring to fig. 3, in some embodiments, the slow start circuit 120 further includes a first capacitor C1, one end of the first capacitor C1 is connected to the drain of the third switch Q3 and the output terminal of the slow start circuit 120, and the other end is connected to the source of the third switch Q3. The reserved first capacitor C1 is provided to protect the third switch tube Q3 from being broken down when the second power supply terminal 112 supplies power to the slow start circuit 120, so as to prevent power-up by mistake, and the first capacitor C1 is not powered up in the process of normally powering up the power calculation module 170.

In some embodiments, the soft start circuit 120 further includes a first resistor R1, a second capacitor C2, and a third capacitor C3, and the first resistor R1, the second capacitor C2, and the third capacitor C3 are connected in parallel between the gate and the source of the second switch Q2. A first resistor R1 is disposed between the gate and the source of the second switch Q2, so that a current signal inputted from the input terminal of the slave start-up circuit 120 flows through the first resistor R1, a voltage difference is generated between the gate and the source of the second switch Q2, and the source and the drain of the second switch Q2 are driven to be connected. Meanwhile, the soft start circuit 120 may filter the input signal of the soft start circuit 120 by providing the second capacitor C2 and the third capacitor C3 in parallel with the first resistor R1.

In some embodiments, the soft start circuit 120 further includes a second resistor R2 and a third resistor R3. One end of the second resistor R2 is connected to the second power supply terminal 112, and the other end is connected to the drain of the second switch Q2; one end of the third resistor R3 is connected to the second power supply terminal 112, and the other end is connected to the drain of the third switching tube Q3. The slow start circuit 120 limits the branch current by providing the second resistor R2 and the third resistor R3, and protects the second transistor Q2 and the third transistor Q3.

In some embodiments, the soft start circuit 120 further includes a fourth resistor connected to the source and the drain of the second switch Q2, and connected to the gate and the source of the third switch Q3. By providing a fourth resistor between the gate and the source of the third switching transistor Q3, the divided voltage of the output voltage of the second power supply terminal 112 acts between the gate and the source of the third switching transistor Q3, and the third switching transistor Q3 is driven to be turned on.

In some embodiments, the slow start circuit 120 further includes a fifth resistor, one end of the fifth resistor is connected to the control device 140, and the other end of the fifth resistor is connected to the gate of the second switch Q2, so as to limit the magnitude of the input current at the input end of the slow start circuit 120 and protect the second switch Q2.

As shown in fig. 3, when the trigger connector 1511 on the back plate 150 is fittingly inserted into the trigger connector 171 on the force calculating module 170, the level state of the input terminal of the control device 140 is a rising edge state. Based on the rising edge state of the input terminal, the control device 140 determines that the force calculating module 170 and the back plate 150 start to be plugged, and increases the current signal input from the control device 140 to the slow start circuit 120, where the input terminal of the slow start circuit 120 is the gate of the second switch tube Q2. The current signal flows through the first resistor R1, a voltage difference is generated between the gate and the source of the second switch Q2, and the source and the drain of the second switch Q2 are driven to be connected, so that the second power supply terminal 112 does not supply power to the gate of the third switch Q3, and the source and the drain of the third switch Q3 are disconnected, so that the power supplied to the second power supply terminal 112 cannot flow through the third switch Q3, but acts on the gate of the switch circuit 130. The current on the power supply branch circuit between the first power supply terminal 111 and the power calculation module 170 is increased, the power calculation module 170 is started and powered on slowly, surge voltage of the power calculation device 100 is avoided when the power calculation module 170 is plugged into the back plate 150, the surge voltage of the power calculation device 100 when the power calculation module 170 is inserted is reduced, and energy impact on the power calculation device 100 is small.

When the trigger connector on the back plate 150 is disconnected from the trigger connection terminal on the force calculating module 170, the level state of the input terminal of the control device 140 is a falling edge state. Based on the falling edge of the input terminal, the control device 140 determines that the force calculating module 170 starts to disengage from the back plate 150, and reduces the current signal input from the control device 140 to the slow start circuit 120, so that the voltage difference between the gate and the source of the second switch Q2 is reduced, and the source and the drain of the second switch Q2 are disconnected. The power supplied from the second power supply terminal 112 cannot flow through the second switching tube, but acts on the gate of the third switching tube Q3 to close the gap between the source and the drain of the third switching tube Q3, so that the power supplied from the second power supply terminal 112 is connected to the voltage zero point via the third switching tube Q3 and does not act on the gate of the first switching tube Q1. The current on the power supply loop between the first power supply terminal 111 and the force calculation module 170 is reduced, and slow power-down of the force calculation module 170 is realized, so that surge voltage generated by the force calculation device 100 when the force calculation module 170 is pulled out is reduced. At this time, the power supply circuit among the force calculating module 170, the connector module 151, the switch circuit 130, and the power supply module 110 is opened, and the energy impact on the force calculating apparatus 100 is small.
