Brief description of the drawings
Fig. 1 is a kind of structural representation of humiture measurement mechanism based on LORA of an embodiment of the present invention.
Embodiment
Fig. 1 schematically shows a kind of humiture measurement mechanism based on LORA of embodiment of the present utility model.
As shown in figure 1, the humiture measurement mechanism based on LORA is somebody's turn to do, including temperature sensor 5, humidity sensor 6 and main control chip 1,
Main control chip 1 is provided with RS485 interfaces 11, LORA interfaces 12, AI interfaces 13, DI interfaces 14 and DO interfaces 15.
In this embodiment, main control chip 1 is Freescale K60 processors.UART ports based on main control chip 1 pass through
The RS485 interfaces 11 that SP3485 chips 2 are expanded out.Main control chip 1 is connected by RS485 interfaces 11 and the communication of PC 4.Based on master
The LORA interfaces 12 expanded out by USR-L100 chips 3 of UART ports of control chip 1, main control chip 1 is by the He of temperature sensor 5
The data that humidity sensor 6 gathers are uploaded by LORA interfaces 12.Analog-digital converter based on main control chip 1 expands out two-way AI
Interface 13, main control chip 1 are connected with temperature sensor 5 and humidity sensor 6 respectively by two-way AI interfaces 13.Based on master control core
The GPIO port of piece 1 expands out two-way DI interfaces 14, for gathering auxiliary information.GPIO port based on main control chip 1 is expanded
Go out two-way DO interfaces 15, when temperature or humidity exceed setting range, main control chip 1 passes through DO interfaces 15 and drives warning device 7.
In this embodiment, warning device is alarm lamp.
In the course of work, standard source is accessed on two-way AI interfaces 13, debugging computer is sent out by RS485 chips to the present apparatus
Calibration command is sent, AI interfaces 13 start to calibrate, and after debugging computer receives return calibration success command, terminate calibration.In two-way
The standard source of another value is intervened on AI interfaces 13, sampled value is read by debugging computer, computer calculation error is debugged, if can
In the range of receiving, then debugging passes through, and the equipment can use at the scene.After the present apparatus is by debugging, you can use, using more
Simply.The device, which is put into, first needs the position of measurement temperature and humidity, cut-in temperature sensor 5 and humidity sensor 6, leads to
Cross debugging computer and the parameters such as address are set to device, can normally be started working after upper electricity.
In a larger arrangement Temperature Humidity Sensor 6 in extensive range, humiture of the utility model based on LORA
Measurement apparatus transmits data by LORA, ensures that signal is excellent and low in energy consumption without amplified signal, while avoids using big
The cable of amount so that installation is extremely simple, drastically increases operating efficiency.
The above is only some embodiments of the present utility model.For those of ordinary skill in the art, do not taking off
On the premise of conceiving from the invention, various modifications and improvements can be made, these belong to protection of the present utility model
Scope.
