Description

[Detailed description of the invention]

[Industrial Application Field] The present invention provides an object in which an object itself undergoes various heat treatments while being moved through a heat treatment area such as a paint drying oven for automobiles, a sterilization oven, or a vacuum deposition furnace. Collect data such as how much temperature there is at various positions in the heat treatment area or what kind of temperature change it shows, and use this collected data to adjust the specifications of the heat treatment equipment and adjust the temperature control equipment. The present invention relates to an industrial temperature data collection, storage, and regeneration system that stores and regenerates data for various purposes such as performance adjustment, quality control, and energy efficiency. [Conventional technology] When measuring the ambient temperature in the heat treatment area and calculating the temperature of the workpiece from this measurement result, the data lacks reliability, so a temperature sensor such as a thermocouple is attached directly to the workpiece. Therefore, it is desirable to directly measure the temperature of the object itself. For this reason, in the past, a cable was used to input the temperature signal measured by this sensor from a temperature sensor attached to the object to be processed into a reproducing device (inputting the displacement signal of the object moving conveyor into this). It was extended for a long time. [Problems to be Solved by the Invention] However, in the case of the conventional means, when the temperature sensor passes through the heat treatment area together with the object to be treated, the cable is easily tangled or caught, resulting in disconnection. There are disadvantages such as the disadvantage that it takes time and effort to unwind and the disadvantage that the conveyor must be driven at a low speed, and as a whole, there are problems in terms of reliability and efficiency. In other words, in the past, the idea was that both the measured temperature signal and the displacement signal should be input to the reproducing device simultaneously with the measurement, so it was necessary to connect a cable to the temperature sensor. Therefore, it can be said that the above-mentioned problems have arisen. An object of the present invention is to provide a system with high reliability and efficiency even though a temperature sensor is attached to the object to be processed. [Means for Solving the Problems] The characteristic configuration of the industrial temperature data collection, storage, and regeneration system according to the present invention is such that the temperature of the object to be processed passing through the heat treatment area is measured. A temperature sensor with a memory that is attached and stores the measured temperature at set time intervals, and measures the amount of displacement of the conveyor that drives and moves the object to be processed, and also stores the measured amount of displacement at set time intervals. In addition to providing a displacement amount detection device with memory, a reproducing device is provided for combining and processing the temperature data and displacement amount data stored in the temperature sensor with memory and the displacement amount detection device with memory by matching data at the same time. The functions and effects are as follows. [Operation] In other words, the temperature measured by the temperature sensor at set time intervals is once stored in the memory attached to the temperature sensor, and similarly, the measured displacement amount for the conveyor that drives and moves the workpiece is stored at set time intervals. The data at intervals are temporarily stored in the memory attached to the displacement amount detection device, and after measurement, the temperature data of the temperature sensor with memory and the displacement amount data of the displacement amount detection device with memory are stored by the reproducing device. , temperature data at a plurality of positions within the heat treatment area can be accurately obtained by combining the data at the same time in correspondence with each other. Temperature sensors with memory are used to temporarily store the measured temperature in memory and then output it to the playback device, so the temperature sensor has a This eliminates the need for long cable extensions. [Effects of the Invention] Therefore, there is no need to extend a long cable from the temperature sensor, which eliminates the disadvantages of using a cable, that is, the tendency for the cable to break due to tangles or snags, and the problem of unwinding the cable. This eliminates the disadvantages of time consuming and the disadvantages of having to drive the conveyor at low speed, and it has become possible to improve reliability and efficiency as a whole. [Example] Hereinafter, an example of the present invention will be described based on the drawings. FIG. 1 is a schematic configuration diagram for data collection and storage, in which the processed material is placed on a conveyor 2 installed in the heat treatment area 1 and is moved through the heat treatment area 1 as the conveyor 2 is driven. A temperature sensor 3 with memory is directly attached to object A, and a displacement counter 5 with memory is connected to a pulse transmitter 4 that detects the displacement of the conveyor 2 and converts it into a pulse signal. is provided. At the start and end sides of the conveyor 2,
A start kicker 6 having the function of starting the operation of the sensor 3 and the counter 5 simultaneously, and a stop kicker 7 having the function of stopping the operation of these 3 and 5 simultaneously are provided. These kickers 6 and 7 are activated when the workpiece A reaches them (or when it passes through them). The sensor 3 and the counter 5 are respectively provided with clocks C and C' of the same type in order to synchronize them in time. Depending on the actuation, the timekeeping action can be started or stopped at the same time. Both clocks C and C' emit pulses at regular time intervals, and when these pulses are emitted, the temperature measured by the sensor 3 at that time and the pulse generator are stored in the memory attached to the sensor 3 and the memory attached to the counter 5, respectively. The integrated value of the number of pulse signals from 4, that is, the measured displacement amount with respect to the conveyor 2 is stored. The temperature data and displacement data stored in the memory tables of the sensor 3 memory and the counter 5 memory are expressed in correspondence with the clock times of clocks C and C' as shown in Tables 1 and 2. Become.

[Table] When the object A has passed through the heat treatment area 1, the sensor 3 is removed and connected to the regenerating device 8 as shown in FIG. This reproducing device 8 uses a microcomputer-based arithmetic processing unit 9 to synchronously combine the temperature data θi and the displacement data χi based on the measured time, and combine data at the same time in a one-to-one correspondence relationship. Then, the combined results are displayed on the printer 10, pen recorder 11, or the like. In this case, the clock on the counter 5 side is
Also serves as C′. By the way, since both the clocks C and C' are of the same type, the time ti measured by the clock C and the time ti' measured by the clock C' should essentially match. is ti and
Since there is a slight deviation between ti' and ti', this can be said to be difficult to avoid even with clocks that use current high-precision crystal oscillators. If ti and ti' deviate, θi and χi will not correspond. In consideration of such a case, the arithmetic processing section 9 detects the deviation between ti' of clock C and ti' of clock C' using ti' as a reference, and also detects a deviation corresponding to this deviation. Correct the displacement data χi (χi
