Abstract
The utility model relates to a remote temperature and humidity measurement and display device comprising three parts: a computer, a communication board card and an acquisition card, wherein the communication board card transmits data to the computer. The acquisition card comprises a temperature and humidity detection module, a display module, a CAN communication module and a one-chip microcomputer module, wherein the temperature and humidity detection module, the display module and the CAN communication module are connected with the one-chip microcomputer module. The communication board card comprises a one-chip microcomputer module, a CAN communication module and a serial port communication module, wherein the CAN communication module and the serial port communication module are connected with the one-chip microcomputer module. The computer processes and stores the data obtained from the communication board card. CAN bus communication is utilized between the acquisition card and the communication board card; and serial port communication is utilized between the communication board card and the computer. A sensor is utilized to realize simultaneous measurement of temperature and humidity data, so that the quantity of sensor is reduced, temperature and humidity data in a plurality of points can be measured, and long-distance temperature and humidity data can be measured.
Description
Technical field
The utility model relates to a kind of measurement mechanism, can to the remote humiture data of multiple spot, carry out measurement and display, especially a kind of remote humiture measurement and display device.
Background technology
Humiture is the most basic a kind of environmental parameter, the people's life and the humiture of environment are closely bound up, in industrial processes, need to measure in real time humiture, also be unable to do without the measurement of humiture in agricultural production, measuring method and the device of therefore studying humiture have great importance.Two separately independently sensor and instrument often to work, make troubles, and integrated Temperature Humidity Sensor and matching instrument are very popular with users.
Once someone attempted to design and a kind ofly can measure temperature, single sensitive element that again can measuring moisture, but do not find yet so far similar sensor listing, and visible difficulty is big, and the key of problem is how two kinds of functional parameters to be made a distinction.So the whole world all adopts respectively thermometric, two kinds of sensitive elements of hygrometric in same sensor.First the developing direction of humiture integrated transducer is exactly to select high-quality temperature-sensitive, humidity-sensitive element like this.Next is to have the matching instruments such as advanced circuit and measurement, control, demonstration.Again, need to be to humiture information realization remote transmission.
Summary of the invention
The object of the utility model design is the deficiency that overcomes prior art, and remote humiture measurement and display device are provided, and this device adopts single-sensor to measure humiture data, and application CAN bus communication technology realizes remote multiple spot humiture DATA REASONING.
The technical solution of the utility model is: a kind of remote humiture measurement and display device comprise computing machine, communication card and capture card three parts, the quantity of capture card can have one or more, after a plurality of capture card image data, by CAN bus transfer, arrive communication card, finally by communication card, transferred data in computing machine.Capture card comprises humiture detection module, display module, CAN communication module and one-chip computer module.Humiture detection module, display module and CAN communication module are connected with one-chip computer module.Communication card comprises one-chip computer module, CAN communication module and serial communication modular.CAN communication module is connected with one-chip computer module with serial communication modular; Computing machine is processed the data that obtain from communication card and store.Between capture card and communication card, adopt CAN bus communication; Between communication card and computing machine, adopt serial communication.
The beneficial effects of the utility model are: owing to adopting technique scheme, when adopting a kind of sensor to realize humiture data, measure, reduced number of sensors, thereby reduced the area of circuit board; The utility model can be measured the humiture data of a plurality of points; Can measure long-range humiture data, maximum distance can reach 10Km.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Fig. 2 is the structural representation of capture card.
Fig. 3 is the structural representation of communication card.
Embodiment
In Fig. 1, the utility model comprises computing machine, communication card and capture card three parts, and capture card is used for gathering humiture data, can have a plurality of different locations that are distributed in, and the capture card of now take is example.Communication card is used for the data that receive from capture card to pass to computing machine.Computing machine passes the data of coming by communication card and processes and store.Capture card is connected by CAN bus with communication card, thereby data are transferred to communication card from capture card.Communication card is connected by Serial Port Line with computing machine, thereby data are transferred to computing machine from communication card.
In Fig. 2, humiture detection module is used for detecting humiture, and this module adopts DHT21 Temperature Humidity Sensor to realize the measurement to humiture.Display module is used for showing the humiture data that collect.One-chip computer module is used for, to the humiture data processing collecting, humiture data being shown on display module, by CAN communication module, humiture data is passed to communication card.Single-chip microcomputer adopts the PIC18F458 of Wei Xin company single-chip microcomputer.
In Fig. 3, one-chip computer module is used for obtaining the humiture data that transmit from CAN communication module, and by serial communication modular, data is passed to computing machine.
CAN communication module is connected by CAN bus with CAN communication module, thereby realizes the connection between capture card and communication card.Between serial communication modular and computing machine, by Serial Port Line, connect, thereby realize the connection between Computers and Communication board.
