Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of power supply TT&C system, comprise manipulate by signal and far-end data switching exchane that computing machine is connected and to be located in rectification rack and with 28 Power Supply Monitoring extension sets of data switching exchane switched connection, Power Supply Monitoring extension set manipulates touch screen interaction by communication interface RS232 serial ports with this locality in rack and is connected, and the control Sampling Interface of Power Supply Monitoring extension set is connected with the output terminal of controller switching equipment in rack.
Multiple stage Power Supply Monitoring extension set is connected with data switching exchane respectively by independently RS422 asynchronous serial port.
The control method of power supply TT&C system of the present invention, comprise the steps: to be divided into sampling power work status information and communication two parts: one, sampling power work status information, monitoring extension set in cabinet for Rectified power source gathers the work state information of rectifier power source by " control Sampling Interface ": input three-phase current, input three-phase voltage, output current, output voltage, temperature information, then the information sampled is processed, see whether power work has fault: as input overvoltage/undervoltage fault, input phase failure fault, overheating fault, output overcurrent fault, leakage current is abnormal etc., two, communication is divided into two parts again: be the communication with local touch-screen and remote control computing machine respectively.(1), by " control interface 2 " communication with local touch-screen.Due to just in rack, communication distance is short, is disturbed probability little, therefore uses RS232 asynchronous communication interface.(2), be by the real-time performance of 10M/100M with the communication of remote control computing machine, be divided into feedback and control two parts.Feedback fraction: the monitoring extension set of 28 rectifier power sources can pass through " communication interface 1 " simultaneously, the status information of power supply is sent on " the 28 road RS422 serial communication interface " of data switching exchane, the 28 tunnel power state information received are aggregated into a road network network signal feedback to the remote control computing machine of radar end by data switching exchane, thus reach a Closed-loop Control Strategy; Control section: the manipulation computing machine of far-end radar can by the start of 28 rectifier power sources or the control command of shutdown, be sent in data switching exchane by network signal, control command is distributed to " communication interface 1 " of the monitoring extension set of 28 rectifier power sources by " 28 road RS422 serial communication interface " by data switching exchane simultaneously, carrys out the machine open/close of Long-distance Control rectifier power source thus.
As shown in Figure 2, remote control computing machine obtains the duty of rectifier power source by the closed-loop control of a feedback: as on-off state, malfunction etc., the work state information of power supply is shown on host computer, whether host computer provides corresponding control command according to the power work condition adjudgement of display, as: if normal boot-strap state, without the need to providing shutdown command, so remote control computing machine will continue through FEEDBACK CONTROL and constantly read power work state, then show, if desired shutdown command is provided, then order sent, by the Internet Transmission of 10M/100M to data switching exchane, data switching exchane judges the validity of order, if invalid command then manipulates computing machine by the network-feedback of 10M/100M to far-end, prompt command is wrong, if order is effective, then effective order is just sent on 28 road RS422 serial communication interfaces by data switching exchane, by it, effective order is distributed to 28 Power Supply Monitoring extension sets simultaneously, after Power Supply Monitoring extension set receives effective order by " communication interface 1 ", program performs this effective order, and order is sent to power supply by " the control Sampling Interface " monitoring extension set, namely power supply makes action of shutting down accordingly, power supply shutdown action needs the regular hour, namely be " time delay " in process flow diagram, then, Power Supply Monitoring extension set continues to sample power supply current operating state information by " control Sampling Interface ", namely be need feedack, sent by " communication interface 1 " and receive feedback information Hou Jiang 28 road feedback information by " the 28 road RS422 communication interface " of data switching exchane and be aggregated into a road network signal and feed back to far-end by 10M/100M " network communication interface " and manipulate in computing machine.Circulate and so forth.
Those skilled in the art will be appreciated that; above embodiment is only used to the present invention is described; and be not used as limitation of the invention; as long as within spirit of the present invention, the suitable change do above embodiment and change all drop within the scope of protection of present invention.
