Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temperature recording device used for recording the temperature inside a refrigerator of a marine container.

[0002]

[Prior Art]

 Fig. 2 shows an example of a temperature recorder installed in a conventional marine container refrigeration system. The conventional temperature recording apparatus shown in FIG. 2 amplifies the signal of the temperature sensor 10 and outputs it to the servo amplifier 3, and the servo motor that is supplied with the deviation output from the servo amplifier 3 and drives the recording pen 6. 4 and a potentiometer 5 which is connected to the servo motor 4 and which feeds back a signal indicating the position of the recording pen 6 to the servo amplifier 3.

Then, the signal of the temperature sensor 10 which detects the temperature inside the refrigerator is amplified by the amplifier 1 and then sent to the servo amplifier 3. Then, the servo amplifier 3 inputs the signal from the amplifier 1 and the feedback signal from the potentiometer 5 indicating the position of the recording pen 6 and outputs a deviation signal to drive the servo motor 4. When the recording pen 6 is driven by the servo motor 4 and moves to the position indicated by the deviation signal of the servo amplifier 3, the deviation output of the servo amplifier 3 becomes zero. Therefore, the recording pen 6 stops at the position indicated by the signal from the servo amplifier 3, and the temperature is recorded on the recording paper by the recording pen 6.

By the way, the type of recording paper is often different for each user, and the servo motor 4 operates per unit temperature in order to adapt the operation of the recording pen 6 to the temperature scale interval according to the recording paper used. It becomes necessary to set the range. For this reason, the servo motor 4 is connected to the setting means 8 having the selecting means 7, and the operating means stored in the setting means 8 corresponding to the kind of the recording paper is selected by the selecting means 7. The operating range per unit temperature output from the setting means 8 to the servo motor 4 is increased or decreased by selecting and setting with a certain selection switch or the like to adapt to the temperature scale interval of the recording paper. ..

[Problems to be solved by the device]

 In conventional temperature recorders, the temperature scale interval of the recording paper varies from user to user, so when delivering or replacing the device, select the operating range per unit temperature of the recording pen corresponding to the recording paper used. It is necessary to set it in the setting means by selecting it with the switch and adapt it to the temperature scale interval, which takes time and may cause the selection switch to be erroneously selected or the selection operation to be forgotten. It was

In order to solve the above problems, the present invention provides a means for adapting to a temperature scale interval corresponding to a recording sheet by only inputting a container name belonging to a user.

[0007]

[Means for Solving the Problems]

 The temperature recording device of the present invention comprises setting means for setting an operating range per unit temperature in a servomotor for driving a recording pen, and selecting an operating range pre-stored in the setting means according to the type of recording paper. In the temperature recording apparatus including the selecting means, the determining means is provided which determines the operating range by identifying the container name, and the selecting means is selected based on the determination result of the determining means. There is.

[0008]

[Action]

 In the above, when the container name is entered, the container name is identified by the identifying means, and the operating range per unit temperature of the servo motor corresponding to the recording paper used for this container is identified. The selecting means is selected based on the result of this determination, and the corresponding operating range is set in the setting means. As a result, the operating range of the servo motor per unit temperature is changed according to the temperature scale interval of the recording paper.

With the above, it is possible to save the trouble of selecting the operating range, and it is possible to avoid a situation such as a mistake in selecting the operating range or forgetting the selection operation.

【Example】

 One embodiment of the present invention is shown in FIG. In this embodiment shown in FIG. 1, a detection signal is input to an amplifier 1 from a temperature sensor 10 that detects the temperature inside the refrigerator, and the output signal of the amplifier 1 is input to the servo motor 4 that drives a recording pen 6. In the temperature recording device in which the servo motor 4 is controlled by the servo amplifier 3 for inputting the output signal of the potentiometer 5 thus selected, and the selecting means 7 is connected to the servo motor 4 through the setting means 8, It comprises a discriminating means 12 connected to the selecting means 7, and an input means 11 and a recording means 13 connected to the discriminating means 12.

In the above, the input means 11 reads the container name of the frozen container and outputs it to the determination means 12, and the determination means 12 converts the container name input from the input means 11 into the data input from the storage means 13. Based on the identification, the operating range per unit temperature of the recording pen 6 is determined, and the determination result is output to the selection means 7. The storage means 13 stores the relationship data between the container name, the type of recording paper used for this container, and the operating range corresponding to the recording paper.

[0012] Here, in the case of a container for ocean shipping, it is obligatory to give a container name, and the naming method is defined by the JIS standard, and the user of this container can be identified from the container name. Therefore, different types of recording paper can be identified by the user from the container name, and by storing this data in the storage means 13, the operating range can be determined by the determining means 12.

Thus, when the container name is input to the input means 11, the discrimination means 12 discriminates the operation range corresponding to the container name, the selection means 7 is selected based on the discrimination result, and corresponds to the setting means 8. The operating range is set. This operating range is output from the setting means 8 to the servo motor 4 to increase or decrease the operating range per unit temperature, and the operation of the recording pen 6 is adapted to the temperature scale interval of the recording paper. The operation of the other parts is the same as the conventional one shown in FIG.

The container is usually equipped with a data logger that monitors the operation of the refrigeration system and stores the operation data, and the container name is always input to this data logger as identity data. Therefore, by outputting the container name input to the data logger instead of the input means 11 to the determination means 12, an appropriate operating range can be surely set in the setting means 8.

According to the above, the operating range per unit temperature of the recording pen corresponding to the recording paper is determined by the determining means and input to the setting means via the selecting means to be set, so that the labor of selection can be saved. At the same time, it is possible to avoid situations such as mistaken selection of the operating range and forgetting the selection operation.

[0016]

[Effect of the device]

 In the temperature recording device of the present invention, the determination means that inputs the container name determines the operation range corresponding to the recording paper used for the container, and the applicable operation range is set in the setting means via the selection means. Besides, it is possible to save the trouble of selection, and it is possible to avoid a situation such as a mistake in selecting an operating range or forgetting a selection operation. In addition, since it is not necessary to select with a selection switch as in the conventional case, this component is unnecessary and the cost can be reduced.
