Embodiment Construction
[0017] according to Figure 1~2 The specific structure of the present invention will be described in detail. The intelligent electronic random sampler includes a casing 5 with a universal charging interface 1, a power switch 3 and a backlight switch 6 of an LCD screen, a liquid crystal display 4 assembled with the casing 5, an external input keyboard and a control circuit. The specification and shape of the shell 5 should be designed according to needs and possibilities, and the number keypad 2 with "0-9" input keys, "C" clear keys and "OK" confirmation keys commonly used in the keyboard and with " The function keypad 7 pointed to by "Up", "Down", "Left" and "Right" are listed on both sides. The input function of the "0-9" input keys can set the range of random number generation according to actual needs, the lower limit defaults to "0", and the upper limit can be set freely. Three random numbers can be generated at a time, which are used in the X-axis, Y-axis, and Z-axis direction...

The invention discloses an intelligent electronic random sampler which effectively solves the problems existing in the prior art such as the influence of human factors, inconvenient operation and the like. The intelligent electronic random sampler comprises a shell and an LCD, an external input keyboard and an SCM control loop, which are assembled with the shell. The technical points of the random sampler comprise that: a random number generation module in the control loop takes an SCM which has the functions of editing and program memory as a core to form a control circuit and is respectively connected with the interface of a simulation adapter, the corresponding interface of a power supply and charge module, the signal input interface of the external input keyboard and the interface of the LCD by the input and output terminals thereof; also by utilizing the signal input by the external input keyboard, the generated random number signal is output to the LCD by the SCM and displayed by characters and numbers. The intelligent electronic random sampler has reasonable structure design, flexible operation and wide application, can ensure the scientific, just, convenient, reasonable, quick and correct sampling, remarkably shorten the sampling time and improve the sampling efficiency.
Description
Technical field [0001] The invention relates to a random sampling device for product quality spot check and inspection, in particular to an intelligent electronic sampler that can ensure the scientific, fair, convenient, reasonable, accurate and fast sampling of batch products by quality inspection agencies. It is widely used in batches Single sampling of products, batch sampling or one-dimensional, two-dimensional and three-dimensional sampling. Background technique [0002] At present, random sampling is an indispensable and important link in the process of quality inspection agencies conducting quality random checks on batches of products. The existing random sampling devices mainly include the following two types: One uses the method of "rolling the dice" to obtain the random numbers that need to be used in the random sampling process. For example, the "random sampler" with the patent publication number CN2057291U discloses a random sampling Dice, it is the most commonly used...
