Abstract

The utility model discloses a kind of direct-reading dial plates based on talking pen principle, the module with point reader identification including OID code information on character wheel and reading character wheel, OID code is carved on the character wheel, the corresponding number of each OID code, the OID code is that the special coating of reflection infrared light is scribed, the optics SENSOR that the module with point reader identification includes MCU and is electrically connected with MCU.The direct-reading dial plate based on talking pen principle, optics SENSOR pixel used by point reader is very low, in addition price is low, identification can quickly carry out at table end, and required power consumption is lower.

Description

A kind of direct-reading dial plate based on talking pen principle

Technical field

The utility model relates to dial plates, and in particular to a kind of direct-reading dial plate based on talking pen principle.

Background technique

Existing dial reading uses the scheme of camera, is mostly that mould group is mounted on to right above dial plate about several centimetres Place is to need to increase a mechanism except whole table, acquires picture by camera, compressed picture is then uploaded to service Device end carries out image recognition analysis.Common camera module is expensive, current intelligent telemetering table design requirement low-power consumption, so Transmission rate is relatively low, and common camera shooting table cannot be identified at table end, thus upload image need occupy it is very long when Between.

Utility model content

The purpose of this utility model is to provide a kind of direct-reading dial plates based on talking pen principle, to solve above-mentioned background skill The problem of being proposed in art.

To achieve the above object, the utility model provides the following technical solutions: a kind of direct-reading gage based on talking pen principle Disk including character wheel and reads the module identified with point reader of OID code information on character wheel, is carved with OID code on the character wheel, often The corresponding number of a OID code.

Preferably, the OID code is that the special coating of reflection infrared light is scribed.

Preferably, the optics SENSOR that the module with point reader identification includes MCU and is electrically connected with MCU.

The technical effect and advantage of the utility model: should direct-reading dial plate based on talking pen principle, used by point reader Optics SENSOR pixel is very low, in addition price is low, identification can quickly carry out at table end, and required power consumption is lower.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: 1 character wheel, 2 OID codes, 3 modules with point reader identification.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of direct-reading dial plate based on talking pen principle as shown in Figure 1, including character wheel 1 and The module 3 with point reader identification of OID code information on character wheel 1 is read, is carved with OID code 2,2 pairs of each OID code on the character wheel 1 Answer a number.

The OID code 2 is that the special coating of reflection infrared light is scribed, and the module 3 with point reader identification includes The MCU and optics SENSOR being electrically connected with MCU.

Working principle: printed on character wheel 1 upper identifiable 2 figure of OID code of point reader (OID code can print very small, And color is close to white, it is only necessary to design the OID code of the corresponding several numbers of corresponding 0-9), optics SENSOR passes through to specific OID code 2 be scanned acquisition identification after, output information code is decoded to single-chip microprocessor MCU, obtains corresponding number.Due to The distance of point reader identification is short, therefore the module 3 identified with point reader can be put in 1 side of character wheel of base table, does not need to be mounted in Off-balancesheet, more securely and reliably.The SENSOR price of point reader is also cheap compared with the SENSOR of common camera.When by being spaced one section Between read character wheel dial plate number, lower power consumption can be made.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
