Mouthful, it is all incorporated into upper-part on a mainboard only more slightly larger than credit card, bottom core control panel has the base of all PC
This function, connection display and keyboard and mouse can operate the various functions of the (SuSE) Linux OS of the inside；
As shown in Fig. 2, upper strata expansion board includes input module, optocoupler output module, communication module, clock module, tamper
Module and indicating module；The input module includes No. four input circuits, and No. four input circuits are connected in parking lot respectively
Ground induction coil and vehicle checker, for detecting the discrepancy of vehicle；The optocoupler output module include four road optocoupler output circuits, four
Road optocoupler output circuit connects the banister in parking lot respectively, for control vehicle argue for the sake of arguing clearance and no through traffic；Described is logical
It interrogates module and includes five road serial communication circuits, four road serial communication circuits are by MAX3232 chips one in 40 pins
Road serial ports expansion controls the LED display and voice broadcast in four tracks by different Enable Pins into five road serial ports,
The function of MAX3232 chips is to carry out the conversion of serial ports level, is that the Transistor-Transistor Logic level that system exports is converted into 232 level or is incited somebody to action
The Transistor-Transistor Logic level that 232 level conversions of input can be received into system；The clock module includes clock chip, peripheral circuit
With external button cell, clock chip and the electrical connection of external button cell, clock chip use RX8025, and clock chip carries out just
It needs to set a current time during beginningization, in the case of normal power supply, time of chip is in the initial time of setting
On the basis of be updated；Clock chip power down, time can lose, so the effect of external button cell is mainly in external power supply
During power-off, power for clock chip；Peripheral circuit mainly selects power supply mode for clock chip, uses when there is external power supply
External power supply is powered, and when external power supply disconnects, is powered using button cell；Entire clock module is mainly system in no net
Network provides system time when connecting；
Network communication module is additionally provided in the upper strata expansion board, network communication module is connected with clock module,
When being powered by 220V and connecting network, clock module is calibrated by network, when scene is obstructed without electricity and network, when
Clock module will carry out time check by IIC clock chips, prevent the scene for powering on or having again from not having the situation of network
The lower time is incorrect；
The tamper module includes microcontroller and microswitch, microcontroller and arm processor electrical connection, when box is lost
And when maliciously being disassembled by others, microcontroller can send a command-destruct to arm processor, all software when box powers on
Self-destruction will be carried out with database, prevents loss of data；
The indicating module has indicator light by cable connection, and indicator light exposes to hull outside, mainly indicates box
Whether power supply powers, system whether normal operation, ground sense input it is whether normal, optocoupler output whether have signal output etc. instructions letter
Breath.
As shown in figure 3, effective detection level of No. four input circuit IN1, IN2, IN3, IN4 is low level, main purpose
It is to detect whether ground induction coil is triggered to know whether vehicle discrepancy, then informs that input module is handled.Therefore,
Input pin is pulled up using pull-up resistor in circuit, enhances input capability, it is right when input pin has low level input
The LED answered can be lit.
As shown in figure 4, the main purpose of output module is the unlatching in order to control banister, when vehicle will enter, at system
Admission of arguing for the sake of arguing is carried out after having managed, appearance, which is deducted fees, successfully carries out clearance of arguing for the sake of arguing.Output circuit is made of four road optocouplers, CTRL1,
CTRL2, CTRL3, CTRL4 controlling switch that optocoupler is switched on or off in order to control, OUT1, OUT2, OUT3, OUT4 are defeated for four roads
Go out.The effect of diode D1, D2, D3, D4 are using diode forward conducting, the characteristic reversely ended, and prevent output circuit from connecing
Inverse time, backward voltage is excessive, burns out optocoupler.
As shown in figure 5, the purpose of communication module is to show the parking stall number in parking lot, vehicle letter to connect LED display
Breath, payment amount of money, the relevant information of residence time.It is 5 that serial ports expensive chip, which expands 1 road serial ports on bottom core control panel,
Road serial ports, particularly, the TXD and RXD of the serial ports all the way on bottom core control panel are turned by MAX3232 chips into line level
It changes, the TXD and RXD after conversion carry out serial ports expansion via serial ports expensive chip SN74LVC2G125 again；Each string
Mouth expensive chip has an enabled pin OE, to use arbitrary serial ports all the way therein, it is necessary to first enable corresponding chip
Pin drags down.
As shown in fig. 6, the purpose of clock circuit is to provide for giving whole system complete time check and correction.Clock chip
Supply voltage is+VCC, and+VCC is that the 3V voltages provided by the 3.3V voltages and button cell provided on bottom core control panel lead to
It crosses BAT54C and carries out what voltage-contrast selected, if the power supply of bottom core control panel is normal ,+VCC is 3.3V, if bottom
Layer core control panel power down, then+VCC is 3V.SCL and SDA on clock chip respectively with the SCL on bottom core control panel and
SDA pins are connected, and can use the Hardware I IC communication protocols of bottom core control panel in this way, be simulated without software
The communication process of IIC.
As shown in fig. 7, decomposing prevention circuit is to carry out an effective protection to the data in embedded box and parking lot, prevent
Loss of data is attacked by other people using to parking data.Decomposing prevention circuit uses 8 pin TI microcontrollers as master control core
Piece is selected between 3.3V and cell voltage that the power supply of chip is provided in bottom core control panel.Cell voltage is most
A height of 3V, when 3.3V power supplies are normal, since 2 terminal voltages of BAT54C are 3.3V, 1 end is cell voltage 3V, and 2 terminal voltages are more than
1 terminal voltage, so choosing supply voltages of the 3.3V as chip at this time.When bottom core control panel power down, 3.3V can not be provided
During power supply, since 2 terminal voltages of BAT54C are 0V, 1 end is cell voltage 3V, and 1 terminal voltage is more than 2 terminal voltages, chooses electricity at this time
Cell voltage 3V is supply voltage.After installation is complete, the shrapnel for switching S1 is pressed embedded box, at this time 1 and 2 conducting, monolithic
The 8 pins input of machine is high level.When embedded box is dismantled again, the shrapnel for switching S1 is bounced, and 1 and 3 is led at this time
Logical, the 8 pins input of STC15W201S becomes low level.8 pins of microcontroller are external interrupt pin, therefore can be by 8 pins
The external interrupt pattern of failing edge triggering is configured to, when there is external interrupt triggering, then illustrates that embedded box is opened, at this time
Message is sent to bottom core control panel by serial ports, informs that embedded box is opened.
