Abstract
A multi-point humiture remote monitoring device for a grain depot is a set of electronic monitoring device used for performing real-time detection to temperature and humidity of a plurality of grain points remotely. The remote monitoring device comprises a humiture sensor, a GSM (Global System for Mobile Communications) and a central controller, wherein the sensors are connected with the central controller AT89C51; the central controller is used for converting temperature values of all points into ASCII codes which are stored in an RAM unit fixed in a processor so as to provide LCD output and allow the GSM to send out as a way of short message; and data sending time interval is set by a control keyboard. The remote monitoring device has a simple structure, and can real-timely detect the temperature and humidity data of the monitoring points in the grain depot, which is sent to receiving equipment of the monitoring personnel remotely, so that the real-time data of monitoring personnel is ensured, and the interior of the grain depot can be processed in time, and as a result, the safety quality of the stored grain is ensured.
Description
Technical field
The utility model belongs to electronic device field.
Background technology
It is crucial that the silo aspect of existing grain depot storage, the moisture in the storehouse are regulated moderate, and it directly has influence on the preservation quality that stores away grain, otherwise it is rotten very easily to go mouldy, and causes a large amount of wastes, and critical moment might can't in time be supplied.Yet the basic major parts of more existing storage monitorings are to lean on people's experience to go evaluation and test, and accuracy remains textual criticism, and some monitoring equipments are arranged, but its basic need takes a sample to the scene, not only bother but also limitation is arranged, and waste a large amount of human resources.
Summary of the invention
The purpose of the utility model provides a kind of through the long-range pen bank multiple spot humiture remote monitor that a plurality of sites of granary temperature and humidity are detected in real time of a cover electronic monitoring equipment.
The utility model comprises Temperature Humidity Sensor, global system for mobile communications, central controller; Sensor links to each other with central controller AT89C51; Central controller converts the temperature value of each node into ram cell that ASCII character is stored in the processor internal fixation and sends with the form of short message with GSM for LCD output, and supervisory keyboard is provided with the time interval of transmission data.
The utility model is simple in structure; Detect the temperature and humidity data of a plurality of monitoring points in the grain depot in real time, and through in the long-range receiving equipment that is transmitted into the monitoring personnel, thereby monitoring personnel real time data guaranteed; To in time handling in the grain depot, guarantee the safe mass of stored grain.
Description of drawings
Fig. 1 is the utility model system schematic;
Fig. 2 is the utility model control section circuit diagram;
Fig. 3 is the utility model gsm module partial circuit figure.
Embodiment
The utility model comprises Temperature Humidity Sensor 1, global system for mobile communications 3, central controller 2; Sensor links to each other with central controller AT89C51; Central controller converts the temperature value of each node into ram cell that ASCII character is stored in the processor internal fixation for LCD output and the form transmission of GSM with short message; Supervisory keyboard 5 is provided with the time interval of sending data, and the total system power supply is direct supply 4, and direct supply voltage is 5V.
Temperature Humidity Sensor can connect 8 or more at most, and the arrangement mode class arranges by oneself according to the shape or the monitoring needs in storage storehouse; GSM is a global system for mobile communications, uses model to be TC35I, is connected with at89C51 through outlet.AT89C51 is a single-chip microcomputer.The course of work is that the temperature-humidity signal that Temperature Humidity Sensor collects is uploaded to single-chip microcomputer, and then sends to user terminal by the single-chip microcomputer processing through gsm module.Mobile phone through control can be provided with the time interval of sending data, like 1 hour, 2 hours or longer time.
Circuit comprises central controller 89C51 part, sensor importation and gsm communication part etc.Soil moisture sensor links to each other with single-chip microcomputer through P3.5; System's (for example 2 hours) central controller whenever at regular intervals reads the temperature value of each node respectively; Temperature value is 12 binary messages, converts ram cell that ASCII character is stored in the processor internal fixation into for LCD output and the form transmission of GSM with short message by central controller.
The setting of systematic parameter is provided with through the mode that mobile phone sends instruction to this module, has omitted keyboard and display, and system stability is easy to operate.
For single-chip microcomputer voltage is 5V, and TC35I voltage is about 4V, and system adopts 74F07 to act as voltage matches and buffering driving for this reason.J2 is a sim card socket, and D1 is a relay indicating light, and the SYNC pin of TC35i has two kinds of mode of operations; Available AT order AT SYNC switches; A kind of is the flash-up situation of indication during emission state, and another kind is the duty of indication TC35i, the flash-up situation that this module is used when being a kind of function emission state in back; When LED extinguishes, show that TC35i is in to close or sleep state; When LED be 600ms bright/represent when 600ms puts out that SIM does not insert or TC35i is carrying out network entry; When LED be 75ms bright/when 3s puts out, show that TC35i has logined enter the internet, is in holding state.Can know the duty of system through this pilot lamp.
The total system power supply is direct current 5V.
