MicroLab - System Overview

MicroLab MK8 System

The Micro Medical MicroLab is a data recording spirometer consisting of a microcomputer unit incorporating a high resolution colour touch screen, Internal printer, USB and RS232 interfaces, mouse and transducer ports and all associated circuitry. Supplied with the microcomputer is a Bi-directional transducer, disposable mouthpieces, mains adapter, nose clip and USB printer cable. The MicroLab is powered by internal Nickel Metal Hydride cells or by the mains adapter supplied. When testing a subject, the Bi-directional transducer is plugged into the microcomputer unit. The Bi-directional transducer is used to measure the subjects expired flow and volume in accordance with the operating manual.

Bidirectional Transducer

The Micro Medical digital volume transducer consists of an acrylic tube with a vane positioned between two swirl plates. The low inertia vane is attached to a stainless steel pivot that is free to rotate on two jewelled bearings mounted at the centre of the swirl plates. As air is passed through the transducer a vortex is created by the swirl plates that causes the vane to rotate in a direction dependant upon the direction of airflow. The number of rotations is proportional to the volume of air passed through the transducer and the frequency of rotation is proportional to the flow rate. The transducer housing consists of a main body that contains a pair of light emitting diodes (LED’s) and phototransistors. The transducer is fixed to the mouthpiece holder that pushes into the main body and is captured by an “O” ring seal. The LED’s produce infrared beams, which are interrupted by the vane twice per revolution. This interruption is sensed by the phototransistors. The output from the collector of each phototransistor will be a square wave with a phase difference between the two of + or - 90 degrees depending upon the direction of flow. The square waves are detected by a microprocessor that measures the period of each pulse and transmits that information to the main unit via a high-speed asynchronous serial link. There is no routine maintenance required for the transducer other than cleaning according to the instructions in the operating manual.

Circuit Descriptions

Microcomputer Unit

Overview (085-01) and Micro controller (085-02). The drawing 085-01 is a hierarchical block diagram showing the connections of the sub-sections. The rest of the drawings are sub-sections and are described in detail below. U1 is a Sharp LH79520 32 bit microprocessor with 32K of Cache Ram, and no internal flash memory. The system clock is supplied by 14.7456MHz crystal (X1). U2 is a reset controller, which holds the reset line low on power up. J1 is the JTAG interface for programming the unit. JP1 is the jumper that must be in place for programming, and removed for normal use. U3 is a multiplexer used to direct the communications to the correct channel on UART1. The directions are printer, MM Sensor 1, and MM Sensor 2.

Power Supply (085-03)

The power to the system is either supplied by the 8.4V NiMH battery or from an external 12V DC regulated power supply. If the external supply is connected, then TR6 & TR12 are switched off and the battery is not used. R8 ensures that the battery is trickle charged at all times.

U40 is the charging circuit for the NiMH battery. The typical charge charge current is about 500mA, which equates to about 375mA out of the 12V supply.

Charging is disabled when the unit turns on with TR23. U4 is a step-down switching regulator used to create the 3.3 and 1.8 volt rails. U6 is a step-down switching regulator used to create the 5V rail. U43 is a 1Hz oscillator used to blink the LED when the battery is charging. If the battery is fully charged CHARGE- is high, and the LED is on – assuming the mains is plugged in. U33 is the power on circuit. If the unit is off and the on/off button is pushed, the unit should turn on. The microcontroller can turn off the unit using MC_OFF+. Holding the on/off button down for 10 secs can also turn the unit off if necessary. U5 is used to hold the unit off if the supply voltage is too low (approximately 5.5V).

R24 and R25 divide the unregulated battery voltage, which is applied to a spare A/D channel in the touch screen driver. The uC continuously examines the reading and gives a battery low or battery dead warning message. Inductors L1 and L2 are placed for EMC filtering and D14 protects the unit from reverse polarity power supply

7

Microlab8 Sensor Interface (085-04)

2 Sensor ports are available for the unit to plug their transducers into (eg. Turbine, SPO2).

U30 is used to translate the levels from 3.3 to 5V. U34, and U35, are used to buffer the receive line to the level translator. This was found to be necessary for the SPO2. TR17 is used to switch the power on for MM Sensor 1. TR19 is used to switch the power on for MM Sensor 2.

Keypad, EEPROM, MOUSE, RTC, RS232 (085-05)

Three buttons are available on the unit.

KEY0 is the ON/OFF button. KEY1 is the HELP button KEY3 is the PAPER_FEED button U8 is used to generate an interrupt to the microcontroller if either the on/off or help button is pushed. The mouse is controlled by 2 data lines. 4 lines come from the microcontroller to interface with these 2 lines. U22, U31 are inverting buffers. TR7 and TR8 are used to drive the data lines low. BAT2 is a lithium coin cell to give the RTC power for up to 10 years. U10 is the RTC and is clocked by a 32.768kHz xtal. D2 enables power to be drawn from the main 3.3V regulator when the unit is on. U25 is a 32Kbyte EEPROM. This is used to store general settings and calibrations.

The uC communicates with the PC an RS232 serial interface at 115,200 Kbits per sec baud rate, with 8 bits data, 1 stop bit and no parity. U9 converts the RS232 signal to a logic signal of 3.3V. The uC uses channel 0 of it’s inbuilt serial controller for RS232 communication.

Printer Driver (085-06)

The printer driver circuit is controlled by a Hitachi H8/3687 microprocessor. It includes the head driver, the motor driver, and the paper detection. The microprocessor has a built in Flash, which needs to be programmed by the main microcontroller, in order for the printer driver to operate correctly. U12 is used to drive the correct signals to rotate the motor. U13 is used to translate the communication levels from 3.3 to 5V. TR1 is to turn off the 5V supply to the printer, when not required. U7 is a linear regulator for the 7V printer head voltage. J7 is the connector for the head J14 is the connector for paper detection J6 is used for debugging the printer, and should never even be populated in production. J12 is the connector for the motor.

8

Display Driver (085-07)

The 3.5” TFT LCD Display is driven directly by the main microcontroller. The display has a built in touch screen and LED backlight, all on the same connector (J8). U28, and U29 are used to invert 2 lines from the processor. U14 is the touch screen controller. U16 controls a constant current through the LED backlight of the display. U15 can adjust the current to which U16 has to control. U17 is a step-up switching regulator used to create the appropriate voltages for the display (AVDD approx 8V, VGH approx 15V, VGL approx –8V).

Sounder (085-08)

The sound driver includes a low-pass filter, a digital potentiometer, and an amplifier. The low-pass filter (R100, and C110) turn the PWM digital signal from the microcontroller into an analog voltage. The digital potentiometer (U18) is used to adjust the volume, and the amplifier (U19) is used to drive the 16ohm speaker with the final signal.

USB Driver (085-09)

The cypress SL811HST (U20) is a host/slave USB controller, which can be used for communicating with a PC or an external printer. In host mode 5V power is supplied through TR13, and switched on with TR14. The chip has is clocked by a 12MHz crystal (X4).

Memory (085-10)

U23 is a 32Mbyte FLASH 28F256P30 used to store all program code, and the files/filing system. U24 is a 2Mbyte SRAM CY62167DV30 used to store all volatile memory, such as video memory, and program memory.
