- the operation of the leak alarm is very specific.
- the counter From start-up, the counter observes consumption for 0 eighteen ten-minute periods.
- the screen displays, by cUgnotating, an alarm message of the type: RISK OF LEAKAGE OF 1 L / 10 min
- the sound leakage alarm then starts if it is activated.
- the operation of consumption backups in the external EEPROM memory is also particular.
- the EEPROM stores the following information
- each recording of the counter value is immediately preceded by a reading of this value (thus, we have the most precise information at the time of recording) I 0
- These backups are used to reset the device with the correct values (in case of power failure for example)
- the time counting by the sampling microcontroller is done as follows • using the Timer 0 of the PIC It is an 8-bit register (256 values) of which one can define a
- 1 5 prescale using the OPTION register of the PIC.
- the prescaler is 1 32
- the clock is at 32768 Hz so the register will overflow at the end of the 0 time T,
- the PIC program detects the passage to 127 of the value of the Timer O (that is to say in the middle of its range of variation: 0..255) and increments the number of seconds with each passage.
- the PIC could send frames every second, but to facilitate reception, we send a frame every two seconds Indeed, for secure reception, it is necessary to have a time between the end of transmission of a frame and the start of transmission of the next one, markedly greater than the maximum time between the transmission of two bits.
- the frame sent by the PIC can, for example, be 64 bits
- the first 32 bits represent the number of pulses counted since the power up of the PIC, and the following 32 represent the number of seconds elapsed since the power up of the peak in starting each time with the most significant bit, which makes it possible to count 4.3. 10 ° pulses, or one million m ⁇ , or a period of about 40 years at a constant flow of 3 m ⁇ / hour.
- the number of elapsed seconds is stored on 32 bits, which makes it possible to count 4,3.10 ° seconds, that is to say approximately 136 years.
- the management of the flow led it is possible, from the number of pulses received, to calculate a maximum terminal value which makes it possible to cause the green led to proportional to the flow using a timer that overflows every ten minutes.
- the value of the maximum terminal gives the time (multipUé per 10 ms) between two lights of the led. The LED stays on for 100 ms.
