The programming of the microcontroller 4 is carried out when building intercom also has a mode in-circuit programming of the microcontroller 4 modify the configuration or upgrading device expansion functions, such as programmable time relay.

The device operates lighting control as follows.

Information signal from the primary transducer 1 is fed to the input of the amplifier-shaper, standardized, and its output is ignal is supplied to the first input of the microcontroller 4, which is the input of the first built-in timer and/or an input that receives the information signal, proportional to the temperature at the installation location of the primary pulse PV 1 and light. The microcontroller 4 cycle per second measures the duration of the signals at its input. In the ROM of the microcontroller 4 stores a table of correspondence pulse signal of the primary pulse PV 1 containing information about temperature, ambient temperature. Next, the microcontroller 4 calculates the true value of illumination introduces a correction in accordance with the temperature of the installation place of the primary pulse PV 1, rewrites the value of the previous measurement cycle to the second register for temporary data storage, and in the first register writes the converted data of the current measurement. In the third register is written, the calculated difference between the current and previous values of illumination. The obtained differential value compares with an average interval of changes of light stored in the microprocessor memory 4, and if the value is beyond the allowable limit, the data of the current measurement are ignored, and the microcontroller 4 carries out re-measurement cycle. Mick is controller 4 when exceeding a differential value of illumination holds up to ten repetitive measurements, delay measurements to ten seconds, after which the value is considered true. Compensation of systematic measurement error occurs with tables and adjustment (calibration) of the coefficients. Code of current measuring light is displayed for visual inspection by the display module 8. The microcontroller 4 reads the binary threshold switching on the lighting from the output of the switch 2, if you have not installed the module interface, and if installed - register for temporary storage of data, compares the code with the computed value and if the threshold is exceeded, generates an enable signal enable lighting with their third exit at the input module lighting control 12, which issues a command to the controller switches the mains supply 3 enable voltage on lamp lighting EL smoothly includes the voltage on N parallel connected lamps lighting EL. The threshold of turning off the lights is calculated by the microcontroller 4 by subtracting from the received from the switch 7 code constant value, amounting to about five percent of the threshold. The hysteresis can be set by the user using the display information by using other values of correction factors. When decreasing illumination below the calculated threshold command from the third output mikroC is ntroller 4 lighting off smoothly. The function of the digital comparator with the feature type “hysteresis”, with temperature correction photocell, with protection from short-term, for up to two minutes, switch lighting, for example due to soft light photosensor headlights of a passing car or intermittent dimming photocell primary pulse PV 1. Time initial pulse PV calculates the microcontroller 4 calendar method, according to testimony real-time clock 9, taking into account the time of sunrise and sunset. Initial setup real time clock 9 is produced at the factory at the time of the commissioning. The microcontroller 4 signal from its first output, which is received at the first input of the power supply by enabling a voltage to the first output of the power supply unit 5 includes at a specified time of the primary pulse PV 1. Additionally, the time on and off the lighting can be adjusted by the microcontroller 4 in the case of the simulation program summer day length in winter, when using the device control lighting in the incubator, greenhouses, etc. the Time of the save operation real-time clock 9 from the backup power source 10 is three months,when using monitoreo (capacitor of a large capacitance electric double-layer), to ten years, when using the lithium element. In emergency mode, in the absence of a signal from the primary pulse PV 1, the operation of the lighting control takes place using the calendar method, taking into account the time of sunset and sunrise. When installing the second module lighting control and second N controller switches the mains supply in the places where need lighting in the daytime, the microcontroller 4 signal from your fourth output controls using the second module lighting control the brightness of lamps. The threshold changes the brightness of the lamps for additional lighting microcontroller 4 calculates with amendments to the basic value stored in the register for temporary storage of the microcontroller 4.

During the initial installation or in the process control device control lighting threshold last set module lighting control 14. It is mechanically fixed to the primary pulse PV and include the desired brightness of the built-in LEDs (radiation band around 540 nm). According to the testimony of the display module 8 and the set threshold switch 7 is judged on the error set and make, if necessary, the corresponding adjustment to set the ADC threshold. Using the module light control is not necessary at each site to wait for the hour of twilight to set the desired threshold enable and disable lighting.

If the impossibility or the difficulty of the strip lines connecting the controller switches the mains supply 3 and the secondary Converter 2, the control device lighting is additionally equipped with a transceiver teams AC 13. In this case, the signal from the sixth output of the microcontroller 4 is fed to the input of the transceiver teams AC 13, the output of which through the power supply 2 is supplied to the AC network. Guaranteed range transceiver teams AC 13 in the city is about 200 m In this case, the composition controller switches enabled receiving device by the AC current, which receives commands, decoding and transmission for execution, i.e. enables or disables the illumination to identify the command.

When the device is connected lighting control to centralized management controllers using interface module with an output two-wire interface I²For communication with the controller type OCELOT/LEOPARD and/or with a standard RS-485 interface for communication with computer automates the trated management system can directly with the highest priority is to issue a command to turn on and off lighting, the control device lighting for identification has its own celebity address and upon receipt of an external request returns to the controller code that is proportional to the measured and the corrected brightness value from 0 to 255, depending on the light, and the greater the amount of light falling on the photoresistor, the lower value returns the sensor, the second byte is the device returns the code that is proportional to the ambient temperature at the installation location of the primary pulse PV 1, and 0°accepted code 00h, sub-zero temperature is transmitted in additional code, such as -25°complies With the code 11100111b (E7h), and a temperature of +25°complies With the code 00011001 (19h).
