Described data acquisition unit, data centralization transmission equipment and wireless forwarding equipment is sending in data deposit data in data buffer, sends after successfully confirming and deletes the data in data buffer again receiving data.
One, data acquisition unit
Data acquisition unit is generally arranged on the position that need to carry out real-time information collection, such as entrance, the community heating entrance and exit etc. of user's heating.For gathering the related data of heating system, as temperature, pressure, flow, valve opening degree etc., and by transferring to data centralization transmission equipment after the form encapsulation according to the rules of the data of collection, be ultimately delivered to server.In addition, data acquisition unit also comprises a display device, can show the data of collection.
The core of described data acquisition unit is single-chip microcomputer, and its principle of work is divided into three aspects:, the one, receive the acquisition from server by serial ports; The 2nd, show the information gathering, and send to server; The 3rd, from warning and the demonstration signalization of external world's input.
(1) receive acquisition
Single-chip microcomputer is as follows by the flow process of serial ports reception server end capture setting order:
The first step: single-chip microcomputer receives the acquisition from server by serial ports, this order is included in the data territory of transmission packet, and the data structure of capture setting order is as follows:
Struct?Gather_Parameter{
Int id; The mark of // collection point, represents the collection point that is numbered id is set, and value is to represent to arrange all collection points at 0 o'clock;
Int period; In // transmission the cycle, the Information Monitoring transmission cycle that expression arranges this collection point is p, the s of unit, and 0 represents only to send immediately an Information Monitoring;
Int type; // send the type of Information Monitoring, 0 represents to send temperature, pressure reduction, valve opening degree and the flow information of Real-time Collection, and 1 represents to send medial temperature, mean pressure, integrated flux and the average switch degree information in one-period
}
When receive after acquisition collection point, if the id in order is 0 or identical with the id of collection point, arrange according to second step or the 3rd stepping line parameter; Otherwise, ignore this order, turn to the 5th step;
Generally, each node can receive the transmission order of period non-zero after starting; In the time that server need to regulate the transmission frequency of certain node, can send to this node the order of a period non-zero; In particular cases, single-chip microcomputer also may send the order that a time period is zero to certain node;
Second step: when single-chip microcomputer is after to receive period be zero order, call immediately once " Information Monitoring shows and sends ", according to type requirement in order, send an Information Monitoring;
The 3rd step: when single-chip microcomputer receives after the order of period non-zero, period in order and type are stored into respectively in two the parameter p eriod and type that single-chip microcomputer safeguards, represent that collection point needs every period to require to send an Information Monitoring according to type second;
The 4th step: the information acquisition cycle of single-chip microcomputer I set temperature sensor, pressure transducer, flow sensor and electrically operated valve is period;
The 5th step: finish.
(2) Information Monitoring shows and sends
The flow process that single-chip microcomputer sends Information Monitoring to server end is:
The first step: single-chip microcomputer obtains respectively temperature information, pressure information, flow information (real-time traffic and integrated flux) and valve switch degree information from temperature sensor, pressure transducer, flow sensor and electrically operated valve;
Second step: in the time that the type of single-chip microcomputer maintenance is 0, send the Information Monitoring of Heating_info_1; In the time that the type of single-chip microcomputer maintenance is 1, send the Information Monitoring of Heating_info_2;
Struct?Heating_info_1{
Int id; // collection point numbering
Int temperature; // temperature
Int pressure; // pressure
Int flow; // flow
Int on-off; // switch degree, span 0-100, the number percent of expression switch
};
Struct?Heating_info_2{
Int id; // collection point numbering
Int temperature; // temperature
Int pressure; // pressure
Int flow; // flow
Int on-off; // switch degree, span 0-100, the number percent of expression switch
Long start_time; Start time in // cycle
Long end_time; // end cycle the time
};
The 3rd step: the data of transmission are sent to display device and show;
The 4th step: when period then, the information exchange of transmission is crossed to serial ports and gives the wireless forwarding being packaged together with data acquisition unit module, and pass to data centralization transmission equipment via wireless forwarding module, sent to server end by data centralization transmission equipment.
(3) receive the warning of extraneous input and show signalization
Extraneous alarm button has 5, and numbering is respectively 1,2,3,4 and 5.1 represents temperature fault, and 2 represent pressure fault, and 3 represent flow fault, and 4 represent switch fault, and 5 represent resultant fault.In the time that user or patrolman find that information that display screen shows is abnormal, can press the corresponding button and continue to carry out fault to server and declare above for 5 seconds.
Display device is provided with two, is numbered 6 and 7.6 represent to show real time temperature, pressure, flow and switch degree, display mode is: [T:** P:** F:** O:**], 7 represent to show medial temperature, mean pressure, integrated flux and average switch degree, start time in cycle and the end cycle time of one-period,, display mode is: [T:** P:** F:** O:** S:** E:**].Wherein T, P, F, O, S and E represent respectively temperature, pressure, flow, switch degree, start time and end time.User or patrolman can continue to switch above for 5 seconds display mode by pressing the corresponding button.
Two, portable collector
