1. and the control type signal is used for controlling the operation of the whole system.
2. And the media signal is used for transmitting service data.
Among the control signals, the reset signal is a kind of signal that must be provided, and as more and more attention is paid to energy saving, in some new wireless communication systems, power-up and power-down control signals are added. When the traffic is not busy, such as at night when the traffic is low, the main control node can power down part of the service node board.

Fig. 4 is a schematic diagram of a service node control circuit according to an embodiment of the present invention, as shown in fig. 4, including 5 modules, module a is a resistor for level isolation. And the module B is a driving isolation device and is used for preventing the level from flowing backwards. The module C is a programmable device for determining what function the current reset signal specifically performs. And the module D is an optical coupler and is used for voltage isolation. And the module E is a power supply module of the service node. The specific implementation mode is as follows:
through the module B, a power control signal CTL _2 is output.
When the service node is in a powered state, module D is controlled by CTL _ 2. When CTL _2 is equal to 0, the service node remains in a power-up state, and when CTL _2 is equal to 1, the service node performs a power-down operation.
When the service node is in a power-off state, module D is controlled by a Reset signal RST (Reset). When RST is 0, the service node is powered on; when RST is 1, the service node remains in a powered down state.
The whole work flow is as follows:
1. setting a counter inside the programmable device to be Count0, simultaneously generating a clock of one period inside the programmable device to be CLK, and setting a judgment value A according to the pulse width of an actual reset signal;
2. when the value of Count0 is less than the judgment value a, CTL _2 is 0; when the value of Count0 is greater than the judgment value a, CTL _2 is 1;
3. when RST is 0, Count0 is cleared;
4. when RST is 1, Count0 counts according to CLK. As long as the value of Count0 is less than the judgment value a, CTL _2 is always kept at 0, so that the service node keeps the power-on state, and the single board only executes the reset operation;
5. when RST is 1, Count0 counts according to CLK. As long as the value of Count0 is greater than the judgment value A, CTL _2 jumps from 1 to 0, the service node performs power-off operation, and the power module turns off output;
6. after the service node is powered off, the drive isolation device is also in a power-down state, and at the moment, CTL _2 is invalid. The optical coupler is controlled by RST signals, and the single plate is always in a power-off state because RST is 1;
7. when the RST jumps from 1 to 0, the service node is electrified to drive the isolation device and the programmable device to start working. The optocoupler is again controlled by the CTL _2 signal. Since RST is 0, Count0 will also remain 0, and the value of CTL _2 will remain 0, the board will not be powered off, but will only be reset.
The embodiment of the invention does not need to add an additional management power supply to the service node or add an additional general IO between the main control node and the service node. By utilizing the circuit design of the multiplexing signal, the reset signal has the self reset function and can realize the functions of power-on and power-off control of the service node. When the service node is in a power-off state, the reset signal realizes the control functions of power-on and power-off; when the service node is in a power-on state, the reset signal specifically realizes the reset function or the power-off function, and the programmable logic device on the service node board judges according to the pulse width of the reset signal.
According to the scheme provided by the embodiment of the invention, the existing devices of the service board and the idle IO of the programmable device can be directly utilized without additionally adding devices, and the cost is hardly increased.
Although the present invention has been described in detail hereinabove, the present invention is not limited thereto, and various modifications can be made by those skilled in the art in light of the principle of the present invention. Thus, modifications made in accordance with the principles of the present invention should be understood to fall within the scope of the present invention.
