The present invention relates to a digital caliper transmission / reception setting transmitter for setting parameters of the wireless device in a measuring device such as a meter.

Conventionally, in a production site such as a factory, various inspections are performed in a product inspection process. In this case, a plurality of measuring devices are placed at the location of the inspection process, physical quantities such as product length and weight are measured, and these measurement data are sent wirelessly to a host computer located in the center, and the host computer The quality level is calculated.
As an example of the measuring device used in the inspection process as described above, a measuring instrument that can display digital measurement data and that can send out the digital measurement data and wirelessly transmits the digital measurement data from the measuring instrument. A measuring device called a digital caliper that is used by holding in hand is known (Patent Document 1).
When the measurement device outputs digital measurement data from the measuring instrument by operating the transmission button while pressing the ID number setting button, the data of a specific digit in the digital measurement data is directly stored in the storage unit as the ID number.

However, the parameter setting methods (i) to (v) described above have the following problems.
That is, for example, in the case of a measuring instrument that is used by hand, such as a caliper or a micrometer, there is a limit to the size and weight of a radio device attached to the measuring instrument, and the size and weight must be reduced as much as possible.

Therefore, in the method of (i) arranging various setting buttons and numeric keys and the method of using the dip switch and rotary switch of (ii), the outer shape must be large due to the space of the component arrangement, the circuit surface, and the components. In addition, a certain amount of weight is required, and a predetermined space must be taken from the viewpoint of operability.
On the other hand, most of the measuring instruments are handled by field workers at the factory production site and inspection room, etc., so it requires specialized knowledge and technology to set various parameters of the radio (iii) PC and dedicated writer It is difficult to write a program using. Similarly, the setting method (iv) is not suitable for field workers because the setting method is complicated.
Further, in the case of (v) the parameter setting method in which the microcomputer or ROM in which the parameter is set in advance is incorporated, it is necessary to prepare as many microcomputers and ROM as the number of setting parameters. There was a problem.

As described above, parameter setting is not possible for a small radio connected to a measuring instrument, so currently, a radio connected to a measuring instrument can only be a simple radio system based on a fixed frequency and fixed communication conditions. The actual situation is that it has not been put into practical use, such as simultaneous radio transmission of a large number of measuring instruments at the same site, and the correspondence to measuring instruments with different communication conditions for each measuring instrument manufacturer cannot be set at the site of use. There was a problem.
The present invention solves such inconvenient problems, utilizes the display function of the display unit of a measuring instrument such as a digital caliper, which is used in a hand equipped with a display that can arbitrarily display digitally, For digital vernier calipers that can set various radio parameters without affecting the size and weight of the radio simply by connecting to the connector for taking out the digital measurement data of this type of digital caliper.

A transmission / reception setting transmitter for a measurement device such as a digital caliper or a micrometer, which is connected to a connector that outputs digital measurement data of the measurement device, and the transmission / reception setting transmitter wirelessly transmits / receives the digital measurement data of the measurement device. A radio unit, a baseband signal processing unit that is connected to the radio unit, modulates and demodulates and includes a radio communication control unit, and a control unit that allows the radio communication control unit to select a control parameter of the radio, Embedded in a radio having at least one or more setting buttons, and the control means includes the A program corresponding to the numerical value displayed on the display unit of the measuring device and the transmission control parameters necessary for transmission of the wireless unit is stored in advance, and the display unit is set to a predetermined value by operating the measurement operation unit of the measuring device. To determine a transmission control parameter necessary for transmission of the radio unit stored in advance with the displayed numeric value, and to set the determined control parameter in the radio communication control unit of the radio Features.

Therefore, according to the above device, since there are only two setting buttons (push buttons), the space for the component arrangement and the circuit surface can be reduced, the external shape of the radio can be reduced, and the weight can be reduced. Can be performed and only the setting button is pressed, so that the operability is improved.
In addition, simply operating the measurement operation section of the measuring instrument and pressing the setting button eliminates the need for specialized knowledge and technology to set various parameters of the radio, improving operability. To do.
In addition, since the measurement operation unit of the measuring instrument is simply operated and the setting button is simply pressed, there is no need to prepare microcomputers and ROMs as many as the number of setting parameters. is there.

  In addition, a small wireless device connected to a measuring instrument can be set with multiple parameters, and can support simultaneous wireless transmission of a large number of measuring instruments at the same site. There is an advantage that the correspondence can be set at the use site and the versatility of the use mode is increased.
