DE1062583B - Arrangement for conversion of measured values - Google Patents

Description

It is known to carry out a coding for the transmission of measured values by using of a compensator or a self-balancing bridge, one assigned to the respective value of the measured variable Combination of relays is brought to the pick-up point. In this way, for example, a corresponding Pulse code signal can be transmitted to a remote display point. To display the measured value as Numerical value are so-called digital display devices known, which are controlled by relays, the be made to respond by the control signal in the sense of the desired display.

The invention is based on the object of converting measured values according to any function, z. B. Correction function to transmit and display or write down.

The invention relates to an arrangement for converting measured values, in which for every possible numerical value a relay is provided for each measured variable, which when the corresponding measured value is present in a known manner by converting the measured variable into a relay position z. B. with the help of a self-balancing bridge is selected, the contacts of the relay assigned to the measured values according to the conversion function, the display * 5 control device, and consists in that the display device with the contacts of the relays, which are assigned to the numerical values of the measured variable pluggable connections or are connected via prepared, exchangeable circuits.

Another embodiment of the invention is, for example, that several display devices are provided, each of which corresponds to a different functional context in another Way is connected to the relay contacts assigned to the numerical values.

The pointing device Ee is activated and the assumed value 65 (40 + 20 + 4 + 1) is displayed.

The circuit excerpt of a further exemplary embodiment is shown in FIGS. 3a to 3c. The relays assigned to the original measured values 1 to 100 in FIG. 3a are denoted by A ... Ή. The measured value 46 causes the relays B, F, G to pick up. As a result, the relay contacts b, f and g are turned over and the relay 46 of the relay field shown in FIG. 3 b picks up. As shown in FIG. 3 c, the relays in the relay field Cc are each assigned three multiple-switched rows of contacts RK ₁ , RK _Z , RK ₃ . These contacts are connected to rows of sockets RB ₁ , RB ₂ , RB ₃ . According to the conversion function, the rows of sockets RB ₁ , RB \, RB ' _{3 can be} connected to rows of sockets of the display device AB _x , AB ₂ , AB ₃ . For example, the sockets belonging to the relay 46 of the socket row RK ₁ , RK ₂ with the socket 60 from the socket row AB ₂ and the socket S are off

A row of sockets AB _{3 of} the display device Ee falling at the resistor Aa is connected as the measured variable.

Lenden voltage assumed, which is implemented in a known encryption device Bb of the type mentioned in relay positions. In the present case it is assumed that the values 1 to 127 after a certain, e.g. B. nonlinear function, as shown in Fig. 2, are to be converted. With Cc 1 is a relay box in Fig. Referred containing 127 relay corresponding to the number to be converted measured values adopted. For example, the measured value 46 to be converted causes the relays 5 "32, 8, 4 and 2 to be attracted at the encryptor output. This causes the relay 46 in the relay field Cc to be attracted, the contacts of which are connected to the elements of the display device Ee via diodes Dd. This is the

den (lines Ll ₁ and -LZ ₂ ) - When the original display value 46 occurs, the relays O ₁ P, R and T pull in, and the corresponding display value 65 is, for example, provided by the numeric display devices (not shown ₎ connected to the sockets AB 1 Display brought. The connection between the connections RB of the relay contacts and the connections AB of the display device Ee can also be achieved by replaceable multiple circuits, for. B. in the form of multiple plugs, contact plates or the like. Are produced. It is also possible to provide several display devices when converting measured values according to different functions, which are connected to the relay field in accordance with the respective conversion function and depending on the
