Description
Technical field
The utility model belongs to intelligence control system field, relates generally to a kind of intelligent valve control system.
Background technology
Industry is the leading of national economy, and water, vapour, wet goods fluid and industrial development have close ties,And fluid be unable to do without network management system in industrial application, there is webmaster must have valve, valve is pipe controlImportant component part in system is the flow for blocking and regulate ducted medium. It is nationalThe indispensable fluid control devices of economic all departments. In some application scenario, to the control of valve not onlyBe only simple switch control, also relate to the control of the various relations such as aperture control and flow, this is rightThe intelligent of valve actuator controller had higher requirement. If poisonous, explosive or inflammableThe production scene of medium, artificial field control is very dangerous, and therefore remote centralized Control is particularly necessary.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of save cost, high reliability, real-time, spiritThe active intelligent valve control system with realizing Long-distance Control.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of smart valve gateSystem processed, comprises power subsystem, controller unit, interface unit, executing agency and display unit is set,Described executing agency comprises the DeviceNet communication bus based on CAN technology.
Described power subsystem comprises sensor data acquisition circuit, signal conditioning circuit, isolated from power.
Described controller unit comprises single-chip microcomputer, chip.
Described interface unit comprises CAN controller, CAN packet sending and receiving device, photoelectric coupled device.
The described display unit that arranges comprises keyboard, LCD, indicator lamp.
In the described DeviceNet communication bus based on CAN technology, valve control system is oneIntelligent node, DeviceNet node is generally described by abstract " object " model, eachDeviceNet node can be regarded as the set of object. Each object has oneself " attribute ",Hold specific " service " and " connection ", can complete certain " behavior ".
Owing to adopting technique scheme, control system receives master node or local control panel is sentAngle set-point control signal, and compare with executing agency angle feedback signal, by-pass valve controlRotating makes it run to the angle of appointment. CAN controller part combines with single chip part, completeBecome the protocol conversion function of DeviceNet, in order to protect CAN controller, improve antijamming capability,Between CAN controller and CAN packet sending and receiving device, add photoelectric coupled device, play buffer action. IfPut part and be mainly used to valve positioner parameter and the setting of DeviceNet network parameter. Display sectionBe used for the setting of display system and current duty forward, reverse or stop only. Not only can receiveLocal control signal, access DeviceNet, eliminates expensive hardwire cost, and can accept long-rangeControl, and finally realize the regulatory function of valve opening.
The beneficial effects of the utility model are: save cost, high reliability, real-time, flexibility and realityThe advantage of existing Long-distance Control.

Detailed description of the invention
As shown in Figure 1, a kind of intelligent valve control system of the utility model, comprises power subsystem 1, controlDevice processed unit 2, interface unit 4, executing agency 3 and display unit 5 is set, described executing agency 3Comprise the DeviceNet communication bus based on CAN technology. Described power subsystem 1 comprises sensor numberAccording to Acquisition Circuit, signal conditioning circuit, isolated from power. Described controller unit 2 comprises single-chip microcomputer, coreSheet. Described interface unit 4 comprises CAN controller, CAN packet sending and receiving device, photoelectric coupled device.The described display unit 5 that arranges comprises keyboard, LCD, indicator lamp. Described based on CAN technologyIn DeviceNet communication bus, valve control system is an intelligent node, and DeviceNet node is generalBe described by abstract " object " model, each DeviceNet node can be regarded as objectSet. Each object has oneself " attribute ", supports specific " service " and " connection ",Can complete certain " behavior ".
The angle set-point control signal that control system reception master node or local control panel are sent,And compare with executing agency 3 angle feedback signals, the rotating of by-pass valve control makes it run to appointmentAngle. CAN controller part combines with single chip part, completes the protocol conversion of DeviceNetFunction, in order to protect CAN controller, improves antijamming capability, at CAN controller and CAN reportBetween literary composition transceiver, add photoelectric coupled device, play buffer action. Part is set and has been mainly used to valveController parameter and DeviceNet network parameter arrange. Display section be used for display system setting andCurrent duty forward, reverse or stop only. Not only can receive local control signal, accessDeviceNet, eliminates expensive hardwire cost, and can accept Long-distance Control, and finally realizes valveThe regulatory function of door aperture.
Above a kind of intelligent valve control system provided by the utility model is described in detail. ThisIn literary composition, apply specific case principle of the present utility model and embodiment have been set forth, above enforcementThe explanation of example is just for helping to understand method of the present utility model and core concept thereof. Should be understood that art neckThe those of ordinary skill in territory, is not departing under the prerequisite of the utility model principle, can also be to this realityCarry out some improvement and modification with novel, these improvement and modifying also fall into the utility model claimIn protection domain.
