Abstract
The utility model discloses a telemetry-type water level detection terminal. The terminal comprises a central processor, an RS485 interface, an AD converter, an ultrasonic wave water level meter, a FLASH memory and an RTC real-time clock. The RS485 interface, the FLASH memory and the RTC real-time clock are connected to the central processor. The AD converter is connected with the RS485 interface. The ultrasonic wave water level meter is connected with the AD converter. By using the terminal of the utility model, through the above principle, the terminal is not polluted by water body; a detection result is accurate and remote control can be realized.
Description
Technical field
The utility model relates to the water level monitoring field, is specifically related to distant reading type water level detecting terminal.
Background technology
In water level data acquisition system and automatic system of hydrological data acquisition and transmission, usually need to, to rivers, lake, reservoir, river mouth, channel, ship lock and various hydraulic structures place level measuring, realize the monitoring to Hydrology.But we wish that this kind monitoring can realize sensing data is gathered, and are uploaded to and collect central station by various communication networking models, central station carries out the model calculation with the data according to collecting and carries out Warning Service.Central station carries out remote measuring, Remote configuration, remote maintenance to remote terminal again.The places such as rivers, lake, reservoir and river mouth are all the modal approach that we take drinking water, and we wish can not destroy water flow structure to the detection of water level, and polluted-water, be not easy to install, and collection signal is simple and debugging is convenient.Now also do not have such checkout gear can meet simultaneously so comprehensive function.
The utility model content
The utility model has overcome the deficiencies in the prior art, and distant reading type water level detecting terminal is provided, and this terminal can not be subjected to water pollution, and testing result is more accurate and can realize long-range control.
For solving above-mentioned technical problem, the utility model is by the following technical solutions: distant reading type water level detecting terminal, comprise central processing unit, RS485 interface, AD converter, ultrasonic water level gauge, FLASH memory and RTC real-time clock, described RS485 interface, FLASH memory and RTC real-time clock all are connected central processing unit; Described AD converter connects the RS485 interface; Described ultrasonic water level gauge connects AD converter.
Further, the model of described ultrasonic water level gauge is TNY sonic400S.
Further, described central processing unit connects wireless network card.
Further, described wireless network card connects antenna.
Further, the model of described RTC real-time clock is DS1302 or DS1307.
Further, the model of described central processing unit is LX4F232H5QCFIGA3.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model adds ultrasonic water level gauge, and this water-level gauge adopts non-cpntact measurement, is not subjected to water pollution, does not destroy water column structure, adopts flange or screw thread to install, easy for installation, is a kind of the detection accurately and the condensate tank of dehumidifier of environmental protection.
2, the data message measured of ultrasonic water level gauge by the converting transmission of AD converter and RS485 interface to central processing unit, central processing unit is processed, again this information exchange is crossed to communication network and carry out long-range transmission, the remote monitoring of realization to level measuring, avoided loaded down with trivial details artificial gatherer process.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated, embodiment of the present utility model is not limited to this.
Embodiment:
As shown in Figure 1, the utility model comprises central processing unit, RS485 interface, AD converter, ultrasonic water level gauge, FLASH memory and RTC real-time clock, and central processing unit connects wireless network card, and wireless network card connects antenna.The RS485 interface of the present embodiment, FLASH memory and RTC real-time clock all are connected central processing unit, and the AD converter of use connects the RS485 interface.The ultrasonic water level gauge of the present embodiment connects AD converter, and the model of ultrasonic water level gauge is TNY sonic400S.The model of the RTC real-time clock of the present embodiment is DS1302 or DS1307, and the model of central processing unit is LX4F232H5QCFIGA3, and the model of wireless network card is WL-167G.
Ultrasonic water level gauge wherein is non-cpntact measurement, is not subjected to water pollution, does not destroy water flow structure, and measurement effect is more accurate.Then this metrical information is converted to information by AD converter to the data that can transmit, by the RS485 interface, pass to central processing unit and process, after processing, data message is carried out to long-range transmission, realize remote monitoring.
Just can realize this utility model as mentioned above.
