Specific implementation mode
To further illustrate that each embodiment, the utility model are provided with attached drawing.These attached drawings are in the utility model discloses
A part for appearance mainly to illustrate embodiment, and can coordinate the associated description of specification to explain that the running of embodiment is former
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
Terminal machine people's control system as shown in Figure 1, a kind of auxiliary that the present embodiment proposes is put on record, using microcontroller as core
The heart, microcontroller are connected with power circuit, clock circuit, reset circuit and jtag circuit and constitute minimum system, microcontroller and outside
Key circuit, identity recognizer, camera, scanner, temperature collection circuit, printer and touch screen connection, microcontroller root
The information provided according to external equipment is also associated with motor-drive circuit, 485 communication modules and data memory module.
Since the control system main task of the application is communication, data access, motor driving and logic in the present embodiment
Control, therefore microcontroller selects 16 super low power consuming single chip processor MSP430F149 as kernel control chip.
One complete control system, matter of utmost importance is exactly to provide power supply module for whole system, reliable and stable
Power module is the premise and basis of system trouble-free operation.MSP430F149 microcontrollers are operated in low-voltage, can be in range
Steady operation.In view of other devices such as MAX3485, MAX3232 etc. work in 3.3V voltages, other related devices work in 5V
Voltage, therefore realize in such a way that 5V turns 3.3V the power supply to microcontroller.As shown in Fig. 2, this control system uses TP7333Q
Linear power supply chip forms main power circuit, and input/output terminal addition decoupling capacitor is disturbed to reduce noise, completed from 5V to 3.3V
Power supply conversion.
After power circuit failure, entire control system will be out of control, considers the importance of power circuit, it is necessary to design standby
Use power circuit.As shown in figure 3, form stand-by power supply circuit by LM1117-3.3, input and output both ends only add capacitance into
Row filtering, LM1117-3.3 is low difference voltage regulator, by can be realized as 1.2V-13.8V outputs by two resistance outside
Voltage.
The clock circuit of the present embodiment uses LFXT1 as inch Zhong Yuan, as shown in figure 4, by the external 8MHz high speeds of oscillator
Crystal oscillator, and external resonant capacitance make microcontroller LFXT1 oscillator operations in high frequency mode, provide the master clock frequency of 8MHz.When
When oscillator fails, DCO oscillators can beat Jian and stable operation, while the automatic clock source for being selected as MCLK automatically in 6us,
To ensure that system maintains operation.
TP7333Q power supply chips can generate reset signal when powering on, therefore by RST signal by after current-limiting resistance
It is directly connected on the reset pin RST on MSP430F149 chips.As shown in figure 5, when reset key is pressed, capacitance can be rapid
Electric discharge, RST pins will receive a low level.Capacitance starts to charge up after button is by loose Jian, and RST pins will restore later
High level.In general, ordinary people needs at least 10ms by one-touch, this is much larger than the effective reset signal of MSP430F149
Seeking time (25us) is wanted to hold time the sum of (250us) with power-on reset signal, it is ensured that system proper reset.
With reference to, to the explanation of jtag interface relevant pins, drawing in conjunction with JTAG downloader interfaces in MSP430F149 specification documents
Foot defines, and design jtag interface circuit is as shown in Figure 6.Jtag interface circuit is relatively easy, and interface pin is corresponding with chip
Pin, which is connected, can be completed.It needs to add explanation, the RST pins of jtag interface are directly connected with the RST pins of microcontroller in Fig. 6
It is to protrude jtag interface circuit, in practical complete circuit, power circuit, reset circuit, jtag circuit can all generate multiple
Position signal, their the RST pins and indirect RST pins with microcontroller are connected directly.
The telecommunication circuit that is made of MAX3485 as shown in fig. 7, the DE pins of MAX3485 link together with RE pins, when
When DE is low level, in a receive mode, when DE pins are high level, MAX3485 is in data transmission modes to MAX3485,
The resistance of 120 Ω is added between the transmission pin 6 and reception pin 7 of 485 bus head and the tail, it is possible to reduce signal is in transmission process
Reflection, enhance the stability of bus.Appropriately sized biased electrical group is added to pin is sended and received, it is ensured that transmitting-receiving is drawn
There are still receivers to set 1 pressure difference in bus free for foot, to avoid generating fault interrupt because of external disturbance.
It needs to drive multiple electric motors in this control system, uses dual H-bridge DC driven chip L298P and field-effect tube
IRL7833S two schemes drive direct current generator.
As shown in figure 8, the motor-drive circuit being made of L298, control signal is received after microcontroller is sent out by bus
It sends out device SN74HCT245 and completes level conversion, finally arrive at L298P.Using L298P control direct current generator when, Input1 pins with
Input2 pins are responsible for controlling the roads A outbound course, and input corresponds to positive and negative two kinds of output respectively when being logical zero 1 and 10.
EnableA pins are the Enable Pins on the roads A, and only when it is high level, OUT1 pins just allow to export with OUT2 pins.
IRL7833S is a channel enhancement field-effect tube, as shown in figure 9, when motor enables control terminal DZCtrl by low
Level skips to high level, and IRL7833 gate source voltages meet unlocking condition at this time, and the conducting of drain-source the two poles of the earth, motor, which rises, to be turned.
Data memory module uses extension storage units of the AT24C256 as control system, microcontroller he pass through I2C is logical
Letter agreement is written and read AT24C256, and as shown in Figure 10, SDA pins and SCL pins are all pulled upward to high level by resistance, protects
For card when bus free, both threads are high level, when the low level for any device output being connected in bus, whole bus
Signal can be lower, i.e., the SDA and SCL of each device are the relationships of "AND", and A0, A1 are the address wires of chip, in bus at most
4 AT24C256 can be met.
This control system also needs to the temperature that film and heat-sealing are cut in monitoring, it is ensured that and cut-out glued membrane and glued membrane sealing smoothly complete,
Using the digital temperature sensor DS180B20 of 1-Wire, temperature detection range is -55 DEG C -+125 DEG C, DS180B20 and list
It only needs number to dig line selection between piece machine to connect, and place connects and connects the pull-up resistor of 5K or so at I/O mouthfuls and can complete temperature acquisition
Circuit, as shown in figure 11.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art answers
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
