To make the purpose of this utility model, technical scheme and advantage of greater clarity, with reference to embodiment
And referring to the drawings, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit the scope of the utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid not
Necessarily obscure concept of the present utility model.
Embodiment：
As shown in figure 1, a kind of intelligent silo measure and control device, including control main frame, control main frame are multiple by network connection
Observing and controlling extension set.Control main frame can be PC, be arranged in microcomputer room, observing and controlling extension set is arranged in different silos.Control master
Machine can be connected using RS-485 buses with observing and controlling extension set, form the serial communication of upper main frame and some extension sets.To avoid leading to
The information collision being likely to occur in news and competition, it is that each slave is addressed first, during communication, main frame first sends address frame,
After each slave receives address frame, compared with Self address, data are if the same sent, it is different then continue waiting for main frame visit
Ask, after main frame receives data.Confirmation signal is sent out to slave, slave receives after confirmation signal that once communication comes to an end；If main frame
Data are not received, then slave repeats to send, untill receiving the confirmation signal of main frame.
Control main frame is controlled to observing and controlling extension set, and control main frame runs backward single-chip microcomputer by certain procedures and sends startup
Signal, start single-chip microcomputer and controlled mechanism.Meanwhile it is the signal and data that single-chip microcomputer is sent to prepare to receive slave computer.It is activated
Slave computer, on the one hand start sensor to measure silo environment, and the signal collected feeding single-chip microcomputer is pre-processed,
On the other hand sent the data storage collected and to center host computer.Meanwhile host computer sends control signal, control is gone to hold
Row mechanism is to reach the environment needed for grain.
As shown in Fig. 2 observing and controlling extension set is built-in with single chip control module, single chip control module connection sensor module and
Executing agency, single-chip microcomputer control on-off switch to control executing agency to act by photoelectrical coupler, and sensor module is by inhomogeneity
The sensor group of type is into being arranged at the diverse location in silo and outside silo, the executing agency is arranged in silo, monolithic
Machine control module is also connected with warning device.
Executing agency includes extension set, the air-conditioning being arranged on silo inwall, and the humidifier being arranged in silo.
Sensor module includes temperature sensor, humidity sensor.
Single chip control module connects key circuit and display circuit
Single-chip microcomputer is also connected with power supply circuit, and the power supply circuit connects solar panel.Electricity is converted into by solar energy
It can be powered.
Upper PC serial line interface uses standard RS232 interface, and the communication mode of epidemic disaster telemetry circuit is RS485
Serial communication mode（In order to improve communication distance and realize more silo observing and controlling）.The two can not be directly connected to, it is necessary to enter line level
Telemetry circuit can be connected by conversion with PC.As shown in figure 3, a piece of MAX232 and MAX1487 is respectively adopted to complete.Conversion
Circuit power pack is realized by 4,7 pin of PC RS232 ports by V1, V2, V3, R4 and electric capacity C6.Whole circuit can
It is made in RS232 connector boxs.
If Fig. 4 is in microcomputer control system, in order to which the data for state of emergency warning system collection of keeping the safety in production are led to
Computer is crossed compared with preset value and is alarmed to remind operating personnel to pay attention to some important parameters or system position, with
Just take urgent measure.Its method be exactly by computer carry out data processing, digital filtering, after scale conversion with the parameter
Bound set-point is compared, if above higher limit（Or less than lower limit）Then alarmed, otherwise just as sampling
Data are normally carried out showing and controlled.The design uses beep sound warning circuit.The design of beep sound remote alarm interface circuit only needs
Commercially available piezo buzzer is bought, buzz sounding is then driven through driver by 1 mouth line of single-chip microcomputer.Piezoelectric type honeybee
Ring device about needs l 0mA driving current, can be driven with a transistor.In Fig. 4, P2.3 connects transistor base input
End.When P2.3 exports high level " 1 ", transistor turns, piezoelectric buzzer both ends obtain about+5V voltages and piped；Work as P2.3
When exporting low level " 0 ", transistor cutoff, buzzer stops sounding.
The control of silo epidemic disaster is realized by air conditioner and blower fan.When condition is adapted to, the wind of inlet and outlet is opened
Machine, draft is formed in silo.Require, cooled using air-conditioning and hydrofuge if Fan Regulation does not reach control.
The adjustment of humidity can also coordinate humidifier to be adjusted.The control of blower fan, air conditioner, humidifier is by single-chip microcomputer and photoelectric coupling
Device into.Its drive circuit is as shown in Figure 5.In Figure 5, light emitting diode is used to refer to show equipment operation.Work as monolithic
When machine output port is low level, LEDl is bright, and optocoupler leads to, and bidirectional thyristor conducting, machine is avoided using thyristor driver equipment
Some shortcomings of tool contact relay driving.Wherein, P1.2, Pl.3, P1.4 port of single-chip microcomputer connect air conditioner, wind respectively
The drive circuit of machine, humidifier.
RS-485 serial port circuits are half-duplexs, and in RS-485 transmitting terminals, Transistor-Transistor Logic level signal is converted into difference by driver to be believed
Number output, is reduced into TTL signal, so RS-485 has very strong and very high anti-common mode disturbances ability in receiving terminal by differential signal
And receiving sensitivity.When transmission data speed reaches 100kb/s, RS-485 communication distance is up to 1200m [14].
In the system, P3.0, P3.1, P3.2, P3.3 DI, RO, RE, DE with RS-485C serial port chips MAX1487 respectively
It is connected, the connection with the upper management end in distal end is then realized by MAX1487 A, B end.RS-485 serial port circuits are shown in Fig. 6.
1）RS-485 electrical characteristic：Using differential signal negative logic, logical one is using the voltage difference of line-to-line as+(2 ~ 6)
V is represented；Logical zero using the voltage difference of line-to-line as-（2~6）V is represented.Interface signal level reduces than RS-232-C, just not
The chip of fragile interface circuit, and the level is compatible with Transistor-Transistor Logic level, can facilitate and is connected with TTL circuits.
2）RS-485 data maximum transmission rate is 10Mbps.
3）RS-485 interfaces are the combinations using balance driver and differential receiver, anti-common mode disturbances ability enhancing, i.e.,
Noise immunity is good.
4）Communication distance maximum RS-485 is about 1219m, peak transfer rate 10Mbps, transmission rate and transmission distance
From being inversely proportional, under 100KpbS transmission rate, it can just reach maximum communication distance, if longer distance need to be transmitted,
Need to add 485 repeaters.RS-485 buses 32 nodes of general maximum support, if using 485 special chips, can reach
128 or 256 nodes, maximum can support to 400 nodes.
It should be appreciated that above-mentioned embodiment of the present utility model is used only for exemplary illustration or explains this reality
With new principle, without forming to limitation of the present utility model.Therefore, without departing from spirit and scope of the present utility model
In the case of any modification, equivalent substitution and improvements done etc., should be included within the scope of protection of the utility model.In addition,
The appended claims for the utility model are intended to fall into scope and border or this scope and border
Whole in equivalents changes and modifications example.
