Abstract
The utility model discloses a kind of flow control special converter, comprise Intelligent Power Module, power module, voltage monitor, current monitor, temperature monitoring, gate circuit, dsp controller, A/D converter, singlechip microcontroller, fault is blocked and unlocked state, described Intelligent Power Module is respectively by voltage monitor, current monitor and temperature monitoring AND circuit connect, described dsp controller is AND circuit respectively, A/D converter, singlechip microcontroller connects, described power module is connected with Intelligent Power Module, described fault is blocked and is connected with dsp controller with unlocked state.Compared with prior art, of the present utility model have following obvious advantage: efficiently solve in chemical enterprise raw material dynamic proportioning process the problem having to because chemical industry fluid has strong corrosivity regularly replace transducer, not only reduce the production cost of enterprise, and also improve the production efficiency of enterprise.
Description
Technical field
The utility model relates to automatic control technology field, specifically a kind of flow control special converter.
Background technology
At present, frequency converter because of energy-conservation, be efficiently widely used in all trades and professions, as various fields such as the energy, smelting, oil, chemical industry, building materials, injection moulding, weaving, printing and dyeing, mining machinery, plastic machines, converter technology have also been obtained and develops on an unprecedented scale, but still be confined on control principle, control algolithm, control performance, and the output characteristic of frequency converter is not combined with noninductive detection technique, thus fail to play substantially effect of the machine in use.Especially in the dynamic proportioning process of chemical industry raw material, because chemical industry fluid has strong corrosivity, after causing the transducer Long-Time Service detecting its flow, accuracy of detection declines, for ensureing product quality requirement, the periodic replacement of having to of its transducer is generally about one month, very worthy about 2500 yuan/, the acquisition cost of transducer makes chemical enterprise year nearly 1,000,000 yuan of wear and tear expense, not only considerably increase the production cost of enterprise, simultaneously due to the frequent replacing of frequency converter, have impact on the production of enterprise to a certain extent, reduce the operating efficiency of enterprise.
Summary of the invention
The purpose of this utility model is to solve inefficiency in prior art, the defect that product loss is serious, provides a kind of flow control special converter to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows: a kind of flow control special converter, comprise Intelligent Power Module, power module, voltage monitor, current monitor, temperature monitoring, gate circuit, dsp controller, A/D converter, singlechip microcontroller, fault is blocked and unlocked state, described Intelligent Power Module is respectively by voltage monitor, current monitor and temperature monitoring AND circuit connect, described dsp controller is AND circuit respectively, A/D converter, singlechip microcontroller connects, described power module is connected with Intelligent Power Module, described fault is blocked and is connected with dsp controller with unlocked state.
Described dsp controller is by photoisolator and external control terminal and digital output model calling.
Described LED display is connected with singlechip microcontroller with key-press module.
Compared with prior art, of the present utility model have following obvious advantage: adopt dsp controller to carry out voltage, electric current, temperature monitoring respectively by gate circuit module, the feedback information with unlocked state is blocked by fault, efficiently solve in chemical enterprise raw material dynamic proportioning process the problem having to because chemical industry fluid has strong corrosivity regularly replace transducer, not only reduce the production cost of enterprise, and also improve the production efficiency of enterprise.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of flow control special converter of the utility model.
Embodiment
For making to have a better understanding and awareness architectural feature of the present utility model and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in Figure 1, a kind of flow control special converter, comprise Intelligent Power Module, power module, voltage monitor, current monitor, temperature monitoring, gate circuit, dsp controller, A/D converter, singlechip microcontroller, fault is blocked and unlocked state, described Intelligent Power Module is respectively by voltage monitor, current monitor and temperature monitoring AND circuit connect, described dsp controller is AND circuit respectively, A/D converter, singlechip microcontroller connects, described power module is connected with Intelligent Power Module, described fault is blocked and is connected with dsp controller with unlocked state.
Described dsp controller is by photoisolator and external control terminal and digital output model calling.
Described LED display is connected with singlechip microcontroller with key-press module.
In practical work process, the input power power supply that output frequency is adjustable after Intelligent Power Module and dsp controller process, namely dsp controller exports its frequency control signal according to setting parameter, thus it is adjustable to make out-put supply frequency realize, its relevant signals is delivered to voltage detection module respectively by input voltage after intelligent function resume module, current monitor module, temperature monitoring module detects, voltage after detection, electric current, temperature value is connected by AND circuit module, when three has one to exceed allowed band, dsp controller then sends fault locking signal, when trouble shooting, then send trouble shooting signal, Intelligent Power Module is worked on, the d. c. voltage signal that Intelligent Power Module exports becomes each voltage gradation required for all modules of system after power module, singlechip microcontroller is connected with dsp controller by its serial line interface, realize the display of system parameters, the operation of button and the setting of frequency control relevant parameter, the setting of fluid flow relevant parameter or check, external control terminal and digital output module are connected with dsp controller through photoisolator, accept in real time or export associated control signal, analog output is realized by A/D converter, and the analog quantity of output can control other equipment or connect correlate meter.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
