The system has compact, aesthetic and generous equipment, and simple and convenient wiring, without programming, can at best collect 56 temperature or humidity detecting points, and can be broadly applied to cold storage, grain storage, military libraries, pharmaceutical companies, cotton mill, libraries, archives and other occasions that require multi-point temperature and humidity detection.

Description

Unibus humiture data acquisition transmitter
Technical field
The utility model relates to a kind of unibus humiture data acquisition transmitter (being RTU).Unibus humiture data acquisition transmitter is that a kind of novel band shows, the humiture data acquisition dispensing device of band control.
Background technology
Present data acquisition system (DAS) mostly is a collection point (analog signals) and joins No. one analog to digital converter, and for many collection points, analog to digital converter just needs a lot, make volume excessive and cost is too high, and collection point one route, wiring construction working amount is big, and application is restricted.
Summary of the invention
The purpose of this utility model is to provide a kind of unibus humiture data acquisition transmitter that is specially adapted to after a large amount of humiture data acquisitions in central station centralized detecting, management.
The technical solution of the utility model is as follows.
Unibus humiture data acquisition transmitter is made up of signal sampling channel interface, humiture demoder, input signal processing unit, storer and CPU (central processing unit), display unit, communication unit and output unit.Digital signal by temperature and humidity sensing digital encoder input is input to the signal sampling channel interface, after be sent to storer and CPU (central processing unit), after central processing unit for processing, send display unit to show the humiture value, output to the central manager station simultaneously.
And the collection point of unibus (digital signal of unique coding) is to link to each other with humiture data acquisition transmitter by a unibus, and the system equipment volume of Zu Chenging is little like this, and wiring is few, and application cost is significantly reduced, and it is very simple to construct.The system that forms with humiture data acquisition transmitter is specially adapted to after a large amount of humiture data acquisitions the system in central station centralized detecting, management, and Temperature and Humidity Control equipment is adopted the system of switch control.This system equipment is small and exquisite, and is elegant in appearance, and wiring is simple and convenient, need not programming, has novelty, practicality, can be widely used in the occasion that freezer, grain depot, military supply depot, pharmaceutical factory, cotton mill, library, archives etc. need the multiple spot humiture to detect.
A unibus humiture data acquisition transmitter (RTU) can be gathered 56 temperature or humidity measuring point at most, and a system can connect 32 RTU at most, and the maximum acquisition capacity that this means a system is 1792 temperature or humidity measuring point.
Description of drawings
Fig. 1 is a schematic block circuit diagram of the present utility model.
Among the figure: 1-temperature and humidity sensing digital encoder, 2-signal sampling channel interface, 3-humiture demoder, 4-input signal processing unit, 5-storer and CPU (central processing unit), 6-display unit, 7-communication unit, 8-output unit, 9-central management station.
Embodiment
As shown in Figure 1, connect successively between signal sampling channel interface 2 of the present utility model, humiture demoder 3, input signal processing unit 4, storer and the CPU (central processing unit) 5; The output terminal of storer and CPU (central processing unit) 5 is connected to display unit 6 and communication unit 7 simultaneously; The output terminal of communication unit 7 links to each other with output unit 8; The output terminal of output unit 8 connects central management station 9.
Its course of work is: be input to signal sampling channel interface 2 by the Temperature Humidity Sensor input of special use, the digital signal of encoding through temperature and humidity sensing digital encoder 1, digital signal transition becomes the digital signal of unique coding to be sent to humiture demoder 3 by unified bus, after decoding, be input to input signal processing unit 4, after be sent to storer and CPU (central processing unit) 5, after CPU (central processing unit) 5 is handled, send display unit 6 to show the humiture value.Simultaneously, signal sends output unit 8 to through communication unit 7.After carrying out conversion of signals, become standard RS-485/CAN signal, output to central manager station 9.Central management station 9 is made up of a RS-485 or CAN translation interface card and computing machine, and the translation interface card is to send computing machine to handle behind the rs-232 standard signal with conversion of signals.
Each road of data acquisition transmitter only links to each other with Temperature Humidity Sensor with single line, can connect 14 successively.Each data acquisition transmitter has 4 road interfaces, can connect 56 temperature and humidity sensing transmitters.A system can adopt 32 (RTU) at most, gather to count and can reach 1792 at most.
