Detailed ways

The technical solutions of the utility model are described in detail below, but the protection scope of the utility model is not limited to the embodiments.

As shown in Figure 1, a medical food water content meter of the utility model includes a housing, a measurement operation display system, and the housing includes a pressure sensor 4, a tray 1 and a load-bearing fixed bracket 2 installed at the bottom of the housing , the pressure sensor 4 is installed in the center of the load-bearing fixed bracket 2, the upper surface of the pressure sensor 4 is provided with a tray 1, and a shock-absorbing foot 3 is also supported between the tray 1 and the load-bearing fixed bracket 2; the measurement calculation display system includes data A processing unit, a logic operation unit and a display unit, the data processing unit receives the pressure data collected by the pressure sensor 4 and calculates relevant data results according to preset functional programs, and transmits the results to the display unit; the data processing unit Contains the water content calculation module.

The above housing is also provided with a display screen corresponding to the display unit, one side of the display screen is provided with a keyboard corresponding to the logic operation unit; the display unit includes a total mass display unit and a water content display unit; the housing is made of plastic as a whole Made by injection molding, the tray 1 is made of stainless steel plate, and the shock-absorbing feet 3 are made of rubber.

Concrete working principle of the present utility model is as follows:

When the object is placed on the tray 1, the pressure is applied to the pressure sensor 4, and the pressure sensor 4 is deformed, so that the impedance changes, and at the same time, the excitation voltage is changed to generate a millivolt analog voltage signal proportional to the gravity . The analog voltage signal is amplified and filtered by the amplifier circuit, sent to the analog-to-digital (A/D) converter, converted into a corresponding digital signal, and output to the data processing unit for operation control. The data processing unit converts the result according to the keyboard command and program. output to the display.

And the water content calculation module in the data processing unit is corresponding to the function key for converting food water content arranged on the keyboard, the water content calculation module directly calculates the water content according to the weight of the food, and finally the calculation result is output to the display , thus showing the water content of each food.

Example 1:

In this embodiment, the keyboard display interface circuit of the shell realizes the function of receiving various commands and data of the man-machine contact parts through the integrated chip 8279: including food water content, data input of weight, zero clearing, division number setting, maximum weighing Volume setting, division value setting, zero point automatic tracking, zero center indication, overload display, automatic accumulation, undervoltage indication and other command input.

The above-mentioned 8279 integrated chip is used as a general interface circuit. On the one hand, it accepts the input data from the keyboard and performs preprocessing, and on the other hand, it realizes the management of the display data and the control of the digital display.

The main functions of the data processing unit in this implementation are: display of parameters such as weight, water content per unit weight, and total water content; data management; data processing; data calculation and other functions.

In addition, considering the diversity of food, in the water content calculation module, the initially entered routine food data is used as the basic data for centralized management; at the same time, certain open permissions are set to add new food water content or modify the original basic information at any time. data supplement. The water content conversion of the water content calculation module in this implementation is shown in Table 1:

Table 1

As shown in Figure 2, the measurement and data processing circuit structure 5 of the present utility model is: the food weight information constitutes a pressure signal, then the analog signal is obtained by measuring the pressure sensor, and then amplified through the amplifier; then the A/D converter is used Convert the input pressure analog signal into a digital signal, and send it to the single-chip microcomputer (built-in data processing unit) for processing; the single-chip microcomputer receives various data and control information sent from the outside, and sends the result to the outside through calculation and processing to realize the display and other needs; finally, the human-machine interface circuit is formed through the keyboard, display, etc., and connected with the host circuit.
