Abstract
The invention discloses a temperature and humidity measurement and control system comprising a temperature and humidity sensor, a temperature regulator, a humidity regulator, an MCU (microprogrammed control unit). The temperature and humidity sensor is used for acquiring field temperature and humidity, the temperature regulator and the humidity regulator are used for regulating temperature and humidity in field respectively, and the MCU is used for controlling operation of the temperature regulator and the humidity regulator. The MCU accesses to a power grid through a power-line carrier modulator-demodulator unit used for modulating digital signals into electric signals capable of being transmitted on a power line, is connected with the power grid through a power-line carrier modulator-demodulator unit used for demodulating the electric signals transmitted in the power line into digital signals, and is also connected with a monitoring center. Transmission of data information between the MUC and the monitoring center can be completed by the 220V power grid through the power line. The temperature and humidity measurement and control system is simple in structure, low in cost and convenient to install, operate, maintain and manage.
Description
Technical field
The present invention relates to industrial control field, be specifically related to a kind of humiture measurement and control system.
Background technology
All kinds of civilian, Industry Control is on-the-spot, the situation of ambient temperature and humidity is important parameter, therefore, to ambient temperature and humidity accurately, in time monitoring, significant.
Power line carrier communication is to take the communication of power system of the transmission medium that transmission line of electricity is carrier signal.Because transmission line of electricity possesses very firmly supporting construction, and set up 3 above conductors (generally having three-phase good conductor and one or two aerial earth wire), so when power transmission line is carried power current, the transmission carrier signal of using, not only economy but also very reliable.This comprehensive utilization becomes the preferential peculiar means of communication adopting of all power departments in the world already.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical matters to be solved is for providing a kind of humiture measurement and control system.
To achieve these goals, the present invention adopts following technical scheme:
A kind of humiture measurement and control system, the Temperature Humidity Sensor that comprises collection site temperature and humidity, regulate temperature control equipment and the humidity control apparatus of on-the-spot humiture, control the MCU controller of described temperature control equipment and humidity control apparatus work, described MCU controller by one for the power line carrier modem access electric power network that is the electric signal that can transmit on line of electric force by digital signal modulated, one is connected with described electric power network for the electric signal transmitting at line of electric force being demodulated into the power line carrier modem of digital signal, Bing Yu Surveillance center connects.
Further, the model of described Temperature Humidity Sensor is SHT11.
Further, described Surveillance center is provided with alarm device.
The invention has the beneficial effects as follows: between MCU controller and Surveillance center, only need to utilize line of electric force, by 220V electrical network, just can complete data information transfer, system architecture is simple, with low cost, be convenient to install convenient operation and maintenance management.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated:
Fig. 1 is the circuit structure block diagram of humiture measurement and control system of the present invention.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of humiture measurement and control system, the Temperature Humidity Sensor that comprises collection site temperature and humidity, regulate temperature control equipment and the humidity control apparatus of on-the-spot humiture, control the MCU controller of described temperature control equipment and humidity control apparatus work, described MCU controller by one for the power line carrier modem access electric power network that is the electric signal that can transmit on line of electric force by digital signal modulated, one is connected with described electric power network for the electric signal transmitting at line of electric force being demodulated into the power line carrier modem of digital signal, Bing Yu Surveillance center connects.
The model of described Temperature Humidity Sensor is SHT11.Described Surveillance center is provided with alarm device.
In use, Temperature Humidity Sensor Real-Time Monitoring environment temperature and humidity, and Real-Time Monitoring value is transferred to the MCU controller being attached thereto, MCU controller is compared this monitor value with preset value, if be less than while presetting minimum, start-up temperature regulating device and/or humidity control apparatus are heated up and/or add wet process, until the environment temperature that Temperature Humidity Sensor detects and humidity value reach while presetting minimum, stop; If being greater than, Real-Time Monitoring value presets mxm., MCU controller is by start-up temperature regulating device and/or humidity control apparatus is lowered the temperature and/or dehumidification treatments, until the environment temperature that Temperature Humidity Sensor detects and humidity value drop to while presetting mxm., stops.
In above-mentioned use procedure, MCU controller will be connected by power line carrier modem, the electric power network He Yu Surveillance center being attached thereto power line carrier modem send the Real-Time Monitoring value of Temperature Humidity Sensor, and the startup of temperature control equipment and humidity control apparatus and closed condition, so that there is comprehensive understanding in Surveillance center to the operation conditions of on-the-spot humiture measurement and control system.Within a certain period of time, if temperature control equipment and humidity control apparatus cannot will send sound and light alarm to the alarm device of normal range Nei， Surveillance center by scene temperature and humidity regulation, to point out user, user can be taken appropriate measures in time.
When needs, change on-the-spot humiture preset value Shi，Ke You Surveillance center and send control information to MCU controller by power line carrier modem and electric power network, thereby realize the change of humiture preset value.
Above-described embodiment is just to allow one of ordinary skilled in the art can understand content of the present invention and implement according to this for technical conceive of the present invention and feature being described, its objective is, can not limit the scope of the invention with this.Every equivalent variation or modification that according to the present invention, the essence of content has been done, all should be encompassed in protection scope of the present invention.
