Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is a temperature recorder that easily measures, records, and reproduces and displays changes in temperature over time, such as constant temperature distribution of fresh food and frozen food, environment during distribution, management of packaging material, living environment, and working environment. The present invention relates to a temperature recorder that can easily grasp the temperature of a narrow place for improvement. Furthermore, by calculating the integrated temperature time, it is possible to clearly know the effect of temperature history and time accumulation.

[0002]

[Prior art]

 Conventionally, various temperature sensors and personal computers have been used to measure and record the temperature changes over time. There are also data recorders that connect sensors and recorders that are integrated with a thermometer. In each case, a technician with specialized knowledge connected to a personal computer or a totalizer to take out temperature data after recording. However, there was no device that calculates the integration of temperature and time.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. (B) With the method of measuring and recording using a temperature sensor and a personal computer, the device became large and it could not be used in a truck during transportation. (B) There was a risk that sensor connections would always be incomplete or broken in small data recording devices that connect sensors. (C) Due to the presence of the connection part, its use was limited because it was vulnerable to humidity and moisture and damaged the equipment. (D) Even with a recording device that was integrated with a thermometer, it was necessary to connect the personal computer with a communication cable after recording and retrieve the temperature data using a predetermined program. (E) Either method is difficult to operate, requires specialized technology to acquire data, and is not a device that anyone can handle, so its range of use was narrow. (F) In addition, the integration of temperature and time is an effective method to evaluate the degree of pain of goods, but until now the integrated temperature had to be calculated, the calculation had to be redone from the newly recorded temperature and time data. . The present invention has been made to solve these drawbacks.

[0004]

[Means for Solving the Problems]

 It has a small card-shaped box with a temperature sensor (1) that measures temperature, a display (2) that displays temperature, date and time, and measurement settings, and an operation unit (3) that inputs measurement settings. The box has a microcomputer unit (4) that has a program for measuring temperature over time, recording temperature, and recording and operating accumulated temperature time. The present invention is a compact time-lapse temperature recorder with a display unit having the above configuration.

[0005]

[Action]

 While confirming the measurement start date and time and the measurement interval time required by the user on the display unit (2), the user inputs them into the microcomputer unit (4) from the operation unit (3). Install this equipment in the place necessary for measurement. The data captured by the temperature sensor (1) at the set measurement start date and time and measurement interval time are stored in the microcomputer unit (4). After the recording is completed, the user inputs the necessary output start date and time and the interval time on the display unit (2) and inputs them to the microcomputer unit (4) from the operation unit (3). After that, while operating the arrow keys, the time and temperature data shown on the display (2) are read. Also, when it is desired to integrate the temperature and time after the start of the test, while checking the display section (2), input from the operation section (3) to the microcomputer section (4) and the calculated result is displayed ( 2).

【Example】

 Hereinafter, examples of the present invention will be described. (B) A small card-shaped box that incorporates a temperature sensor (1) for measuring temperature has a display (2) that displays temperature, date and time, and measurement settings, and an operation unit (3) that inputs measurement settings. . The box has a microcomputer unit (4) that has a program for measuring temperature over time, recording temperature, and recording, managing, and calculating integrated temperature time. (B) The present invention has the above structure, and when using this, the user confirms the measurement start date and time and the measurement interval time necessary for the measurement on the display unit (2) while the micro unit is operated from the operation unit (3). Input into the computer section (4). Next, install this equipment in the place and package required for measurement. The data captured by the temperature sensor (1) at the set measurement start date and time and measurement interval time are stored in the microcomputer unit (4). (C) After the end of recording, the user inputs the required output start date and time and the interval time on the display section (2) and inputs them to the microcomputer section (4) from the operation section (3). After that, while operating the arrow keys, the time and temperature data shown on the display (2) are read. (D) After the recording is completed, the user inputs the required output start date and time and the interval time on the display unit (2) and inputs them to the microcomputer unit (4) from the operation unit (3). After that, while operating the arrow keys, the time and temperature data shown on the display (2) are read. Also, when it is desired to integrate the temperature and time after the start of the test, while checking on the display section (2), input from the operation section (3) to the microcomputer section (4) and the calculated result is displayed ( 2).

It is a temperature recorder that can easily grasp the temperature in a narrow space in a truck or packing material to manage and improve the working environment. (F) With the conventional method of measuring and recording using various temperature sensors and personal computers, the size of the device becomes large, or there is concern about the connection of the sensor, and it is vulnerable to moisture and water. In addition, it is difficult to operate because it is necessary to retrieve temperature data with a prescribed device or program, and specialized technology must be acquired. Since it is not a device that anyone can handle, its range of use was narrow. (G) The present invention can be used independently, and is easy to operate and has a display section, so it can be used by anyone at the site of use. In addition, the effect of accumulating temperature history on the quality of the target item can be measured with a function that integrates the product of temperature and time, which was not found in conventional measuring devices and temperature measurement programs. (H) For fresh food, temperature control is important for quality maintenance and control. Especially for vegetables, fruits, flowers, etc., the concept of cumulative temperature time is more effective and can be used for storage, storage, and transportation management to maintain quality. There is a high correlation between accumulated temperature and quality of fruits and vegetables, and the applicant reported a high correlation between broccoli quality and accumulated temperature at the Japan Society of Agricultural Machinery Kanto Chapter meeting (August 27, 1992), but other vegetables such as spinach However, it shows a high correlation.
