EXAMPLES
Fig 1 gives a schematic view of a model example of the said device The device consists of two buffer attenuators (Bl 1 and Bl 2 BUFFER ATTENUATOR) which are respectively connected to the varicap voltages of the TV set and/or video unit Connected to the TV set and video unit are the digital inputs IN1 IN16, while to these inputs a presence sensor is connected Varicap voltages, after passing through the attenuator buffers, are connected to an analogue multiplexer AMUX, which on its part is connected to A/D converter The said device is provided with two microcontroller units, MCU1 and MCU2 Connected to the first such unit are the AMUX multiplexer and the A/D converter Digital inputs by means of input-output logic are connected to the MCU1 microcontroller unit By means of this same logic the said microcontroller is also connected to a modem which, on its part, is connected by means of interface circuit to a serial interface RS232 To the said first microcontroller unit and by means of the SPI serial peripheral interface a real time clock RTC is also connected To the MCU1 microcontroller unit are connected, by means of control logic (MCU LOGIC), EPROM permanent memory and random access memory (RAM) Power to the random access memory and to the clock is buffered by means of storage battery To this microcontroller unit is also connected a remote control receiver The entire system is provided with common power supply from the mains The MCU1 microcontroller unit is also connected to interface circuit for serial RS232 interface A second microcontroller unit is connected to the first MCU1 unit by means of serial peripheral interface SPI This second microcontroller unit is connected, too, to EPROM permanent memory, and by means of indication logic (Ind LOGIC) it controls the indication facility (display) of the device
The said device operates as follows
Switching on of TV set is read through one of the digital inputs Then MCU1 starts reading varicap voltage (or voltages, provided that video is also switched on) by means of the
AMUX analogue multiplexer and A/D converter Via digital inputs is possible to track the status of the TV set (whether meter or decimeter band) and video watching The A/D converter value that has been read is recorded into a sequence of memory cells The average value plus the signals for meter or decimeter band allow for determination of the TV program that is being currently watched Upon installation of the device, the operator by means of remote control unit memorises into the EEPROM the values of the A/D converter for all TV programs that are watched within the table of channels Afterwards, each switching of programs is compared with the table so that the program which is identified together with the real time are recorded into the RAM memory On the other hand, into the EEPROM ID hours are recorded for reporting to the master computer at the center for observation of TV audience When the specified time comes, the device by means of modem connects to the telephone line and transmits to the mastei computer the contents of its RAM memory TV viewers operate this device through a remote control unit (with infrared rays) whereby commands from the control panel through the remote control receiver are read by the MCU1 TV viewers may register themselves, express evaluations give answers to questions, participate in an interview which is loaded by the master computer The dialogue between viewers and device is carried out by means of the remote control unit and the display unit Message from the MCU1 are sent by the serial peripheral interface SPI to MCU, while MCU2 on its part using the program in the EPROM and the indication logic (Ind LOGIC) writes the messages via INDIKATION Into the EPROM of MCU2 it is possible to memorise ASCII tables in different languages In cases of drops in power supply, both controllers receive a PF signal (power fail) after which into the RAM memory the contents of all mam registers is saved, and it is only then when the microcontroller stops After resumption of power supply, the RTC clock sends a signal to the microcontroller which, upon resumption of operation, reads the registers saved in the memory, thereby starting from the point at which the stop has occurred
In cases of confusion in the program, which may happen when interference of signals occurs, there is a system for identification of errors in the program, such as non-existent instructions or failure to pass through a program branch for a specified time This results in another re-starting of the microcontroller with no loss of the contents of memory and clock
