Abstract
The utility model discloses a humidity control case which comprises a sealed case body, wherein an inner valve, an outer valve and a control circuit for driving the inner valve and the outer valve are arranged in the sealed case body; and the control circuit comprises a singlechip which is connected with a temperature sensor and a humidity sensor and is also connected with a humidity absorbing box used for dehumidifying the sealed case body. A dehumidification case is internally provided with the temperature sensor and the humidity sensor so as to collect current temperature and humidity data; the data and the state are displayed through a liquid crystal unit; function modes are switched through key-presses; and the inner valve, the outer valve and the humidity absorbing box are controlled through an AVR (Automatic Voltage Regulation) singlechip so as to fulfill the functions of humidity absorption, humidity discharging and humidity holding, and the control is accurate.
Description
Technical field
The utility model relates to a kind of opertaing device, particularly a kind of moisture control unit.
Background technology
Humidity is the important detected parameters of industry such as electronics, chemical industry, electric power, machine-building.Because the non-linear output and the consistance of humidity sensor are relatively poor, make humidity measurement method and means relative complex, and the characteristic of humidity sensor is closely related with temperature again, temperature variation directly influences the sensor parameters characteristic variations, therefore moisture measurement is than other physical quantity complexity, and the control difficulty is big.Belong to only to survey for the most equipment of high humidity at present and do not control, or adopt simple switch control, precision is low, error is big, energy consumption is high, often can not satisfy technological requirement.
Summary of the invention
It is core devices based on single-chip microcomputer that the purpose of this utility model provides a kind of, and high-precision sensor is as detecting element, precise control, the humidity control box that cost is low.
The technical solution of the utility model: a kind of humidity control box, comprise airtight casing, the control circuit that is provided with interior valve, outer valve in the airtight casing and drives inside and outside valve, described control circuit comprises single-chip microcomputer, single-chip microcomputer is connected with temperature sensor and humidity sensor, and single-chip microcomputer also is connected with the moisture absorption box that is used for dehumidifying in the airtight casing.
As preferably, described single-chip microcomputer is connected with the keyboard that is used to set dehumidifying information.
As preferably, described single-chip microcomputer is connected with the LCD that is used to show dehumidifying information.
As preferably, described inside and outside valve connects motor, and motor is driven by control circuit.
As preferably, described single-chip microcomputer is the AVR single-chip microcomputer.
Of the present utility model except that wet tank is installed temperature in case, humidity sensor is used to gather current temperature, humidity data, finish data, state demonstration by liquid crystal cells, and come the handoff functionality pattern by button; Rely on the AVR single-chip microcomputer that inside and outside valve and moisture absorption box are controlled, finish moisture absorption, hydrofuge, humidity maintenance function, precise control.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a control circuit block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
As Fig. 1,2, a kind of humidity control box, comprise airtight casing 1, the control circuit that is provided with interior valve 3, outer valve 4 in the airtight casing 1 and drives inside and outside valve, control circuit comprises single-chip microcomputer, single-chip microcomputer is connected with temperature sensor and humidity sensor, and single-chip microcomputer also is connected with the moisture absorption box 2 that is used for dehumidifying in the airtight casing.Single-chip microcomputer is connected with the keyboard that is used to set dehumidifying information.Single-chip microcomputer is connected with the LCD that is used to show dehumidifying information.Inside and outside valve connects motor, and motor is driven by control circuit.
According to the actual conditions of industry spot, with highly reliable, low-cost, multi-functional be principle of design, the single-chip microcomputer of present embodiment adopts the mega16 AVR of atmel corp single-chip microcomputer as main control chip.
The principle of work of humidity control box is as follows:
Inside and outside valve is isolated external environment, moisture absorption box, airtight casing mutually, when humidity is higher than setting value in the airtight casing, the AVR single-chip microcomputer by driving circuit with external valve closing, internal valve open, system's moisture absorption; When being lower than setting value, with inside and outside valve open, airtight casing is in communication with the outside, extraneous soft air enters, system's humidification; When ambient humidity satisfied setting value, inside and outside valve was all closed, and state keeps; During the moisture absorption,, need the heating hydrofuge if the hygroscopic agent performance in the moisture absorption box descends, at this moment, interior valve closing, outer valve open, system's hydrofuge.
