The invention relates to instrument engineering and can be applied in the watch industry to control the quality of watch movements.

The purpose of the invention is to improve the quality of control of watch movements by increasing the reliability of assessing the quality of watch movements by measuring a number of parameters, as well as increasing productivity when assessing the quality of watch movements through the implementation of the principle of multi-channel operation of the device.

The device allows you to quickly and simultaneously determine the instantaneous daily rate, the amplitude of balance oscillations and the presence of balance pumping immediately for N watch movements, which is very important in terms of mass production of products based on watch movements. All this makes it possible to increase the reliability and productivity of assessing the quality of watch movements, i.e. ultimately, the quality control of watchmaking quality is significantly improved, and, consequently, the quality level of products manufactured on the basis of watch movements is increased.

FIG. 4 prints of symbols; N is the channel number; 1 is the pulse number (as shown in FIG. 2); T / N, I) - an array of source Information; iT (N) - an array of averaged data of the diurnal variation; VB (N) is an array of balance pumping out, T is the etching period; A (N) is an array of amplitudes.

Sensors 1 through the drivers 2 are connected to the first inputs of the multiplexer 3, to the second input of which the first output of the 4 channel counter is connected, connected by the first input to the first output of the reference clock 5. The output of the multiplexer 3 is connected to the input of the one-shot 6 and the second input of the pulse counter 7, first input which is connected to the first output of the reference clock 5, and the output to the second input of the memory block 8, which is connected to the first output of the first output of the 4-channel counter, the third input to the one-shot output

6, the fourth input - with the second output of the reference clock 5, and the output - with the second input of the microcomputer 9. The first

the input of the microcomputer 9 is connected to the second output of the 4-channel counter, in which the second input is connected to the output of the reset shaper 10. The input of the reference clock 5 is connected to the output of the generator 11 clock pulses, and the output of the microcomputer 9 is connected to the input of the display 12. Sensors 1 connected to the driver 2 form the input channels 13.

The generator 11 clock pulses (Fig. 2) consists of three inverters 14-16, resistors 17 and 18, capacitor 19 and quartz 20.

Practical implementation of the rest

The blocks of the structural scheme, for example, for an 8-channel device, can be represented as follows: sensors 1 — typical piezoelectric sensors, drivers 2 — typical, multiplexer 3 — based on K155KP7, counter 4 channels — based on K155IE7, reference clock 5 — counter or timer KR580VI53, one-shot 6 - K155AGZ, counter 7 pulses K155IE2, memory block 8 - based on a typical BISOS, microcomputer 9 - single chip microcoupler K1816, shaper 10 reset - К155АГЗ, display 12 - standard display, compatible with a microswitch microswitch K1516, K155GZH, display 12 - standard display, compatible with a microswitch K1816 microprocessor, reset shaper 10 - K155AGZ, display 12 - standard display, compatible with a microswitch microelectric K1816 .

The device works as follows.

After setting the clock mechanisms into all N input channels 13, the device is started up by setting the counter 4 to the zero state through the driver 40. From the first output of clock 5, the first inputs of counters 4 and 7 receive pulses, the period of which is equal to the reference period T5 for the clock mechanisms type (for example, for alarm clocks Td 0.6 s). As a result of the arrival of the pulse from the clock 5

counters 4 and 7 respectively increase their state by one, while the outputs of counters 4 and 7 form the address bus of memory block 8. With the arrival of a pulse from the clock mechanism installed in the first channel 13 of the device (N 1), the counter 7 increases its state by one, and the one-shot 6 imparts a resolution to the third input of block 8

to record information from the reference clock 5 into the memory zone of block 8 reserved for the first channel. During the entire period T., data on points in time (signal from the reference clock 5) of pulses from the clock mechanism installed in the first input channel 13 will be recorded in the zone of the first channel 13 After the arrival of the next pulse of the reference period T from the clock 5, the counter 4 increases its state by one, and counter 7 is reset to the zero state. Now, in block 8, similarly to the previously described, information about the moments of arrival of pulses from the clock mechanism installed in the second input channel 13, i.e. for N 2. In this case, the information in block 8 is entered respectively into the memory zone allocated for the second channel 13. Thus, the operation of the device continues until the state of counter 4 becomes equal (2N + +1), after which counter 4 stops and at its second output the value of logical 1 is set. By this signal, microcomputer 9 reads the information recorded in memory block 8 and calculates the averaged instantaneous daily course, balance pumping and amplitude of balance oscillations for each of the clock mechanisms using a certain algorithm.

The essence of the methodology for obtaining and processing data on the movement of watch movements is as follows. Over the entire period of receiving information from watch movements, i.e. during the monitoring of the N clock mechanisms by the device - t (2N + 1) Tg, each input channel 13 is connected twice to the memory block 8. At the same time, in the memory zone of unit 8, for each channel 13, the times of arrival of pulses from controlled clock mechanisms are recorded. Taking into account that at the first and second outputs of the reference clock 5, the frequencies are rigidly connected to each other and multiples, then block 8 does not record the time from the beginning of the observation, but the time from the beginning of the observation in this channel 13. It has, at the end of the observation, two pairs of values this time for each controlled clockwork, as well as the number of periods TD between

By referring to the same channel 13, it is quite easy to calculate the average daily variation, balance pumping and the amplitude of balance oscillations for each channel. However, gfy records of the previously mentioned information about the time of arrival of pulses from clock mechanisms for one

period T, i.e. To a single channel 13, these pulses can arrive in three different time combinations shown in FIG. 3. With the arrival of pulses in the combinations shown in FIG. 35 and 3b, the choice of a reliable moment for recording data on the arrival time of pulses from clock mechanisms is complicated. In order to completely eliminate the influence of this effect on the reliability of the obtained data, in the algorithm of the microcomputer 9, shown in FIG. 4, special logistic operations are provided, which at the initial information processing stage in microcomputer 9 allow the selection of the most suitable pulses (more precisely, the time of their arrival), on the basis of which the characteristics of the clock mechanisms will be calculated. The calculated microcomputer 9 according to the previously mentioned algorithm shown in FIG. 4, the averaged instantaneous diurnal course, balance pumping and the amplitude of balance oscillations for all simultaneously controlled watch movements are displayed in an explicit form (for example, in a row-based (channel-by-channel) digital form).
