Brief description of the drawings
Fig. 1 is hardware system structure figure of the invention；
Fig. 2 is software function diagram of the invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, the tele-control system for solar energy irrigated area sluice of the invention, including nucleus module, GPRS module, DC MOTOR CONTROL module, jaw opening sensor, level sensor.Wherein nucleus module uses stm32F103 micro-controls Device processed, GPRS module, level sensor are connected by serial communication with nucleus module, DC MOTOR CONTROL module, aperture sensing Device and other sensors are using the connection of mobus buses.Nucleus module is controlled and monitoring sluice motor, solar energy system, GPRS The work of module etc., realize water gate control and with cloud platform telecommunication.The system is used for the one with independent intellectual property right It is changing, using sun-generated electric power, can by cloud platform carry out remote wireless monitoring, exist for the existing small miniature sluice in the country The deficiency of the aspects such as efficiency, control mode, water quantity management precision, Communication Control network, construction cost, with wireless remote, can Carry out Intelligent cluster scheduling, low-power consumption, low cost, easily lay etc. advantage.
Because the system aperture is using reliable ripe Modbus type collection data, two interruptions, one are set for this Individual is UART communication disruptions, and another is Interruption, because the agreement of Modbus is without corresponding synchronous or communication control Whether making mechanism, is to judge the timely response of each sensor according to certain time limit using the purpose of Interruption.
CRC check and timing verification are carried out first after sensor response message is obtained, and then carry out data reasonability school Test, realize the high reliability of data.Accurately dislocation code is then provided if there is mistake.
The system sets Interruption timer4 to control acquisition function rhythm, timer4 to use two kinds of working frequencies, Sluice stop and without operation in the case of, it is per second（1000ms）Poll water levels of upstream and downstream, a jaw opening sensor are low to reach The purpose of power consumption operation；When running or having operating instruction, polling cycle is changed into 100ms, the state higher to obtain real-time Data.
It is one of main characteristics of integrated sluice that remote wireless control is performed, and module is integrated with GPRS module, using wide The 2G/3G networks of general distribution can realize that irrigated area optional position lays and need not lay communication cable, and sluice passes through radiolink Data are received and sent, realizes that real time water level aperture flow monitoring is uploaded and control information receives and performs, so as to concentrate intelligence Can water resource scheduling offer condition.Using TCP connections, Automatic-searching GPRS network after electricity, completes registration in module for GPRS communications Cloud Server request connection, this module station number is reported after setting up connection afterwards, is periodically connect to Cloud Server status data thereafter Dispatch command is received, when state does not change, to save flow, short heartbeat packet is only sent and is kept TCP connections, realized low Flow is reliably connected and the preferable interaction characteristic of real-time.
Also include cloud server terminal monitoring module, every state of cloud server terminal monitoring module Real-time Feedback service end, user The operation conditions of service end can be understood according to cloud server terminal monitoring module.
Also include the sluice condition monitoring platform being connected with cloud server terminal monitoring module, sluice condition monitoring platform can be real When return to every data message of each gate, the later stage more user can be actually needed increase and delete sluice number.
Cloud server terminal also converting web page operation interface, the instruction of mobile phone A PP, realize that office's control and mobile terminal are remotely controlled System.Mobile phone A PP shows running status and real-time running data and fault alarm, i.e., show gatage, water by appropriate format The information such as position situation, flow, spacing and alarm, and control operation interface is provided, keying lock can be carried out in the case where there are authorization conditions The operations such as door, conversion aperture, setting flow.
Cloud server terminal is also realized tidal data recovering, arrangement, storage and is presented.Dispatching algorithm Pre feasibility is controlled, is studied many Plant scheduling and control strategy dispatching algorithm.System can also receive the control instruction that each Terminal Type sends, after treatment to one The sluice remote control module of body sends instruction, and monitors ruuning situation.Module is possible to receive and process in time alarm signal Breath, takes emergency measures and to terminal PUSH message.
Sluice is the system control object, to realize low-power consumption Driven by Solar Energy, is run using direct current generator dragging sluice, Motor control employs the DC MOTOR CONTROL module of maturation, with the control of various speed-regulating modes, brake and rotating speed, realizes function Powerful and safe control system.DC MOTOR CONTROL module is connected using Modbus buses with core controller.
Motor control process is as follows：
4) electrical motor gearshift starts and stops：
The system, as sluice power, to provide system reliability, reduces rush of current, electric motor starting using 24V direct current generators Gear shift mode is used with stopping, being started using climbing in 5 seconds during startup, operated steadily accurately.Deceleration in 3 seconds is then provided with during stopping Docking process, because the sluice speed of service is slow, this setting does not interfere with the system corresponding time.
5) system uses several working ways, is respectively on-site manual pattern, the automatic aperture control in scene, the automatic stream in scene Amount control, the automatic water rate control in scene, it is long-range open and close control, the control of remote auto aperture, the control of remote auto flow, it is long-range from Dynamic water rate control etc..Each way this software all by calculating final water gate position data, software auto-controll operation process, directly Predetermined work aperture is reached, can also be automatically switched off under water rate control pattern.
6) gate speed of service control, the system obtains gatage using absolute encoder, and sluice operation is calculated in real time Speed, sluice ruuning situation is monitored by velocity amplitude, calculates parking spot.
Process fault detection is as follows：
4) each sensor communication check
The following failure of sensor feedback Data Detection：
(3) send without ack signal after REQ, i.e., without response failure, possible failure cause is that holding wire failure, sensor crash With sensor station number mistake etc.；
(4) data station number is received wrong, inquiry sensor of interest and feedback transducer station number are inconsistent, are sequential the reason for possible Disorder, perversion etc.；
5) data correctness inspection
Feedback data is unreasonable, i.e., super large or extra small data etc. occurs in measured value.
6) sluice state-detection, speed of service control
(1) calculated in sluice running and monitor that the sluice speed of service is specific function, the reasonability of speed can more be shown in Rigorous accurate judgement sluice running status.Sluice starts and stops using accelerated mode, starts and was accelerated using 5 seconds, Stop then using 3 seconds ways of deceleration, reduce the rush of current that sluice operation motor is produced, make the reliability that operates steadily.
(2) sluice operation troubles detection：Sluice traffic direction and state are not inconsistent with instruction, and such as instruction is starting gate, but Sensor display sluice is static；Instruction is that sluice stops, and sensor shows sluice in movement.
