Description

cycles, the delay element 10, the trigger P, the recording device 12.

Digital meter-controller works as follows.

In the initial state at the clock and informational outputs of the measuring device 3, there is no signal, at the inverse output of trigger II there is a single signal, and all other elements are in the zero condition. From the output of the sensor 2, the measuring device 3 receives a signal about the ash content of the charge for coking, in which a signal is generated about the average ash content of the charge during the time measured.

After the time tn has elapsed, a clock pulse appears at the output of the measuring device, which is fed to the input of the 9 clock counter and the switch 4 of the outputs.

After a fixed time in pause from the information output of the measuring device, the stream of pulses arrives at the input of the decoder 7, the number of which is equal to the ash ash measured during the time t.

The clock pulse is recorded in the clock counter, and a control signal appears at the output of the first decoder 8, which is fed to the input of the decoder 7. In this case, the result of the measured ash content is recorded at the input of the memory cells 5. The first clock pulse, also entering the input of the switch 4, will trigger the connection of the output of the common cell 5 of the memory to the corresponding output of the switch 4, at which the result is obtained on measuring the ash content of the charge over time,

In the second and subsequent n cycles, the operation of the meter regulator does not change.

After the p-th cycle, ash content in memory cells 5 is recorded in time nU. The content of any memory cell 5 in any measurement cycle is determined by the formula:

 apvLe m,

(I Nt 0рк in "V.t-ft-4B"

where: w is the number of the cell, k is the number of the measurement, k and n is the number of memory cells, and is the number of cycles measured by multiples of n.

b is the number of measurement cycles of non-multiple p. During operation of the device from the information output of the switch 4, the signal about the ash content of the charge enters the recording device 12.

 Thus, the proposed meter-controller allows to receive signals corresponding to measurement times tn, 21 3tft..ntn, each of the regulating signals being the average ash content of the conveyor over the conveyor during the elapsed measuring time.
