Description of drawings
Fig. 1 is a kind of timesharing multi channel signals switching device shifter structural drawing described in the utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of timesharing multi channel signals switching device shifter described in the utility model mainly comprises pulse signal generation module, relay module, supply module and state display module.Pulse signal generation module has a plurality of output channel DO1......DOn, the cycle of sending is the pulse signal of T (as: 2s) to different passages successively, the signal of relay module output is switched to different passages, then the multiple DCS system supplymentary equipment that is connected on the relay module is checked, relay module comprises the relay of several cascades, with binary channels relay SRB 01 is example, two channel C H.1, CH.2 is independent mutually, and two channel C H.1, CH.2 all has four tunnel outputs, when the CH.1 of relay and CH.2 received the pulse signal that pulse signal generation module sends, output switched.According to the needs of reality DCS system supplymentary number of devices to be detected, can also pulse signals generation module channels quantity and the port number and the signal output port of relay quantity and each relay expand.Supply module is responsible for supplying with the required power supply of signal.The state display module is responsible for monitoring check result and is shown the inspection state.
This device course of work is as follows:
When 1, pulse signal generation module channels DO1 sends the pulsed D O01 of first 2s, the first passage CH.1 of first relay switches, the power supply that supply module provides exports second channel C, four signal output ports H.2 of first relay to, detects first DCS system supplymentary equipment that is connected these four ports;
2, after the qualified non-fault of first DCS system supplymentary monitoring of equipment, the DO01 pulse disappears, the pulsed D O02 of second 2s sends from pulse signal generation module channels DO2, H.2, second channel C of first relay switches, the power supply that supply module provides exports first channel C four signal output ports H.1 of second relay to, detects the second batch of DCS system supplymentary equipment that is connected these four ports;
3, after the second batch of qualified non-fault of DCS system supplymentary monitoring of equipment, the DO02 pulse disappears, the pulsed D O03 of the 3rd 2s sends from pulse signal generation module channels DO3, the first passage CH.1 of second relay switches, the power supply that supply module provides exports second channel C preceding four signal output ports H.2 of second relay to, detects the 3rd batch of DCS system supplymentary equipment that is connected these four ports;
4, after the 3rd batch of qualified non-fault of DCS system supplymentary monitoring of equipment, the DO03 pulse disappears, the pulsed D O04 of the 4th 2s sends from pulse signal generation module channels DO4, H.2, second channel C of second relay switches, the power supply that supply module provides exports second channel C back four signal output ports H.2 of second relay to, detects the 4th batch of DCS system supplymentary equipment that is connected these four ports;
By that analogy, finish the DCS system supplymentary equipment inspection that is connected all relay signal output ports, the state display module is responsible for monitoring check result and is shown the inspection state.
