Description

Remote temperature management method using a mobile device that receives power through a communication cable}

The present invention relates to a method for low-cost quality improvement and manufacturing cost reduction in manufacturing fields such as food and cosmetics, where temperature management is an essential management factor for quality, and selects a plurality of temperature measurement locations or identification value IDs (130). It relates to a remote temperature management method using a mobile device using a mobile device for temperature measurement and a temperature measuring device that transmits the temperature to the mobile device.

In addition, the temperature measuring device is characterized in that it operates by receiving operation power from a communication cable connected to the mobile device without a separate power supply device (battery, etc.).

In addition, the present invention relates to a wired/wireless communication method for a mobile device to transmit temperature data received from a temperature measuring device to a remote production management system.

In order to strengthen manufacturing competitiveness, the production information management system (MES) is not an option to manage quality information such as temperature, pressure, weight, time, and speed as well as production information such as production quantity, defect cause, and defect quantity generated in the manufacturing process. It has become a necessity.

In particular, in manufacturing fields such as food and cosmetics, which include manufacturing processes such as mixing, fermentation, and oven, temperature control of mixtures and fermented products is performed as an essential management factor for quality.

However, unnecessary duplication in which the operator measures the temperature of a plurality of mixtures and fermentation products (by multiple temperature measurement locations or identification value IDs) with a thermometer, records them manually in a notebook, and then inputs the temperatures recorded in the notebook into the production management system again. Occurrence of work causes worker workload and inefficient temperature management.

In addition, in the process of re-entering the temperature of a plurality of mixtures and fermented products (by multiple temperature measurement locations or identification value IDs) measured by a thermometer and recorded on Paper into the production management system, erroneous input or omission occurs. There is a problem that the reliability of the temperature data and the quality of the product are lowered.

In the conventional technology, in order to solve the above problem, there is a case of using a wireless temperature measuring device that measures the temperature and transmits it to the production information management system wirelessly, but the conventional wireless temperature measuring device uses a temperature measurement location or identification value ID (130) There is no selection function (for example, when the function of selecting a plurality of temperature measurement locations or identification value IDs 130 is implemented in the wireless temperature measuring instrument, the size of the wireless temperature measuring instrument becomes very large, making it difficult to carry and expensive, making it impossible to use). With a function of wirelessly transmitting only temperature data, the production management system that receives the temperature data can distinguish which temperature measurement position or identification value ID (130) is the temperature data among a plurality of temperature measurement positions or identification value ID (130). There is a problem that is difficult to use in actual manufacturing sites. The wireless thermometer has a limitation in that it can be used only in the field of repeatedly measuring and managing only one temperature measurement location, and the conventional wireless thermometer has a built-in battery, so the built-in battery must be charged frequently. There is a hassle in using it.

The present invention selects a plurality of temperature measurement locations or identification value IDs 130 using a mobile device and transmits temperature data for the selected temperature measurement locations or identification value IDs 130 to a remote production information system. It aims to provide a method for doing so.
