The utility model content
The purpose of this utility model is to solve the problem that prior art exists, a kind of environmental parameter harvester based on the rs485 agreement is provided, can be monitored parameters such as temperature, humidity, illumination, carbon dioxide, soil moisture soil moisture content, liquid level, wind speed in real time, be there is the advantages such as low-power consumption, wiring is simple, data transmission is timely.
In order to reach above-mentioned technical purpose, the utility model by the following technical solutions:
A kind of environmental parameter harvester based on the rs485 agreement, comprise the environment pick-up transducers, rs485 data processing and control plate and the intelligent terminal that connect by wireless network, described rs485 data processing and control plate comprises chip, single-chip microcomputer, reset circuit and the operation monitoring circuit that carries out the rs485 serial communication.
As such scheme preferably, the model of the chip of the described rs485 of carrying out serial communication is MAX1482 or MAX485.
As such scheme preferably, described environment pick-up transducers comprises temperature sensor, humidity sensor, optical sensor, carbon dioxide sensor, liquid level sensor, air velocity transducer and soil moisture soil moisture content sensor.
As such scheme preferably, described intelligent terminal is one or more in mobile phone, flat board, notebook, PC.
As such scheme preferably, also comprise the remote data server be connected with described rs485 data processing and control plate.
Owing to thering is said structure, the utility model has the following advantages compared to existing technology: the utility model provide can a kind of environmental parameter harvester based on the rs485 agreement, can be monitored parameters such as temperature, humidity, illumination, carbon dioxide, soil moisture soil moisture content, liquid level, wind speed in real time, be there is the advantages such as low-power consumption, wiring is simple, data transmission is timely.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural framing figure that Fig. 1 is the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of environmental parameter harvester based on the rs485 agreement, comprise the environment pick-up transducers, rs485 data processing and control plate and the intelligent terminal that connect by wireless network, described rs485 data processing and control plate comprises chip, single-chip microcomputer, reset circuit and the operation monitoring circuit that carries out the rs485 serial communication; The model of the chip of the described rs485 of carrying out serial communication is max1482 or max485, and described environment pick-up transducers comprises temperature sensor, humidity sensor, optical sensor, carbon dioxide sensor, liquid level sensor, air velocity transducer and soil moisture soil moisture content sensor; Described intelligent terminal is one or more in mobile phone, flat board, notebook, PC.
The utility model provides a kind of environmental parameter harvester based on the rs485 agreement, comprises the chip that carries out the rs485 serial communication, adopts this chip to carry out data transmission, transfer rate is high, the signal level of this chip is low simultaneously, and chip is not fragile, and the noise immunity of this chip is good in addition.This harvester can carry out the comprehensive Department of Survey in ground to parameters such as temperature, humidity, illumination, carbon dioxide, soil moisture soil moisture content, liquid level, wind speed and have the advantages such as low-power consumption, wiring is simple, data transmission is timely.
The principle of work of the environmental parameter harvester based on the rs485 agreement that the utility model provides is: by temperature sensor, humidity sensor, optical sensor, carbon dioxide sensor, liquid level sensor, air velocity transducer and soil moisture soil moisture content sensor difference collecting temperature, humidity, illumination, carbon dioxide, liquid level, wind speed and soil moisture soil moisture content information, these environmental informations send to and are processed in single-chip microcomputer and preserve by max1482 or max485, then send to intelligent terminal by max1482 or max485.The operation monitoring circuit is monitored the operation of single-chip microcomputer, when single-chip microcomputer breaks down, provides signal to reset circuit, by reset circuit, the fault of single-chip microcomputer is recovered.
Further, the environmental parameter harvester based on the rs485 agreement that the utility model provides also comprises the remote data server be connected with described rs485 data processing and control plate.The environmental information of processing through single-chip microcomputer also can send to the remote data server by max1482 or max485 and be backed up and record.Can check and understand environmental information by the access remote data server.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
