Abstract
The utility model provides a redundancy control system in a secondary water supply system. The redundancy control system comprises a control cabinet and two sets of detectors, water pressure sensors, power supplies, electric water pumps and PLCs (Programmable Logical Controllers) for backing up for each other, wherein the two sets of equipment can be switched mutually; and when one set of equipment becomes abnormal or a certain part becomes abnormal, corresponding standby equipment or a certain corresponding part starts, so that normal water supply of the entire equipment is not influenced. According to the redundancy control system, the equipment can be switched without halting when the equipment becomes abnormal or in the cleaning process of the equipment, so that safe water supply is realized.
Description
Technical field
The utility model relates to the automatic control system field, relates more specifically to the redundancy control system in a kind of secondary water supply system.
Background technology
The common alleged secondary water-supply of people, the unit of referring to or individual supply water city public water supply or self-built facility through storing, pressurizeing, and supply user or personal form by pipeline again, and therefore, secondary water-supply is the only selection mode of present high-floor feedwater.
The secondary water-supply facility is mainly that to remedy the municipal water supply line pressure not enough, guarantees to live, lives in high-rise crowd's water and set up.Compare former water and supply water, the safety and reliability of secondary water-supply all is subject to the civic extensive concern always.But traditional secondary water-supply equipment is owing to all be single system water supply, and a certain water pump or miscellaneous part occur just needing to shut down maintenance when unusual in pipe network, can't realize user's normal water supply, bring hidden danger for stability and the safety of water supply.
The utility model content
Cause the problem that can't supply water for solving the shutdown that brings owing to mechanical disorder in the secondary water supply system, the utility model provides the redundancy control system in a kind of secondary water supply system.
The utility model is achieved through the following technical solutions: the redundancy control system in a kind of secondary water supply system, comprise switch board and the mutually redundant detector of two covers, hydraulic pressure sensor, power supply, electric water pump, the PLC controller, the hydraulic pressure of hydraulic pressure sensor in can the Real-Time Monitoring pipe network, monitoring result is sent to the PLC controller with the form of the signal of telecommunication, the PLC controller with data analysis after control electric water pump unlatching or close, the mutually redundant detector of described two covers, hydraulic pressure sensor, power supply, electric water pump, the PLC controller connects successively, parallel with one another between parts of the same race, parts of the same race are provided with the terminal that can control its work or disconnection when connecting, terminal is controlled by the PLC controller, have or not equipment to occur in the detector real-time monitoring system unusual, when a cover normal operation, another set of for subsequent use; System detects a cover and unusual or a certain parts occur and occur when unusual, and the PLC controller can switched terminal, corresponding component is started replace unusual component working, thereby can not stop the user being supplied water in the equipment of the realization handoff procedure.
The beneficial effects of the utility model are: the redundancy control system in the described secondary water supply system, realized having realized supplying water safely and steadly unit exception being arranged or equipment being carried out in the cleaning process switching device do not shut down by the technique on redundant control.
Description of drawings
Fig. 1 is the redundancy control system control chart in a kind of secondary water supply system
The specific embodiment
Redundancy control system in a kind of secondary water supply system, comprise switch board 40 and the two mutually redundant hydraulic pressure sensor 10 of cover and hydraulic pressure sensors for subsequent use 11, power supply 50 and standby electric power 51, electric water pump 30 and reserve pump 31, PLC controller 20 and PLC controller 21 for subsequent use, the hydraulic pressure of hydraulic pressure sensor in can the Real-Time Monitoring pipe network, monitoring result is sent to the PLC controller with the form of the signal of telecommunication, the PLC controller with data analysis after control electric water pump unlatching or close, the mutually redundant detector of described two covers, hydraulic pressure sensor, power supply, electric water pump, the PLC controller connects successively, parallel with one another between parts of the same race, parts of the same race are provided with the terminal that can control its work or disconnection when connecting, and terminal is controlled by controller.
It is unusual that hydraulic pressure sensor 10 detects system pressure, the transfer of data that hydraulic pressure sensor 10 can detect is to PLC controller 20, system detects that water pump 30 occurs unusual in the cover that is moving, the control terminal that the PLC controller 20 unusual water pumps 30 of switching and reserve pump are 31 makes reserve pump 31 replace unusual water pump 30 work.Thereby can not stop the user being supplied water in the equipment of the realization handoff procedure.
The present embodiment is the explanation of a kind of situation of the present utility model only, is not to restriction of the present utility model, and the scheme that all those skilled in the art can realize according to manual all should be as protection domain of the present utility model.
Claims (1)
1. the redundancy control system in the secondary water supply system, it is characterized in that: comprise switch board and the mutually redundant hydraulic pressure sensor of two covers, power supply, electric water pump, the PLC controller, the hydraulic pressure of hydraulic pressure sensor in can the Real-Time Monitoring pipe network, monitoring result is sent to the PLC controller with the form of the signal of telecommunication, the PLC controller with data analysis after control electric water pump unlatching or close, the mutually redundant detector of described two covers, hydraulic pressure sensor, power supply, electric water pump, the PLC controller connects successively, parallel with one another between parts of the same race, when a cover normal operation, another set of for subsequent use; System detects a cover and unusual or a certain parts occur and occur when unusual, and another set of middle corresponding component starts replaces unusual component working.
