Abstract

A host apparatus collects the physical or chemical quantities of articles, which have been measured by a plurality of measuring devices, for example, vernier calipers. Each calipers has a caliper unit as a measuring means, a dip-switch, a CPU, a RAM, and a transmitter. The caliper unit has an analog-to-digital (A/D) converter. The dip-switch is operated, thus setting an ID number of the device, before the device is used. The ID number is stored into the RAM. When the transmission button of the device is pushed, the CPU edits the digital value supplied from A/D converter and the ID number stored in the RAM, thereby forming a serial-data message. This message is transmitted by a transmitter, in the form of a radio message. The host apparatus has a receiver and a host computer. The receiver received the serial-data messages transmitted from the measuring devices. The host computer collects the values measured by the devices and contained in the serial-data messages, in accordance with the ID numbers also contained in the serial-data messages.

Claims5

Dependent claims

A measured data collecting system comprising:

a plurality of measuring device means each of which includes:
measuring means having a data transmission function of transmitting digital output data obtained by operating said measuring means,
measured data message preparing means,
(a) in an identification number setting mode, for storing a numerical signal of a predetermined digit of the digital output data, which is input from said measuring means, as an identification number having a unique number for identifying each measuring device means, and,
(b) in a measurement mode, for incorporating the digital output data, which is input from said measuring means, and the identification number stored during said identification number setting mode, into a serial measured data message, and
transmitter means for wirelessly transmitting the serial measured data message which is prepared by the measured data message preparing means during said measurement mode;
receiver means for receiving the measured data message which are sent from said plurality of measuring device means;
and
host computer means for identifying the measured data on the basis of the identification number included in the measured data messages received by said receiver means and for collecting the measured data thus identified.
