Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing a controller for an electric fusion joint according to a first embodiment of the present invention. Power is input from the AC power supply 20 to the power supply unit 9 of the controller 1 for the electric fusion joint. This input voltage is, for example, AC
100V or 200V AC. Before the fusion work, first, the electric fusion joint 10 and the resin pipe are held by a clamp. Next, input data is input to the input unit 14. Here, the input data is information necessary for determining the power supply amount to be input to the electrofusion joint 10. As input data, for example, a joint maker name, a joint item,
There are joint nominal diameter, joint resistance, energizing time, output voltage, resin name, resin wall thickness, etc. The input data input to the input unit 14 is transferred to the microcomputer unit 4 of the main control unit 3.

At the time of the fusion work, electric power as a DC output set based on the input data is supplied from the power supply unit 9 to the electric fusion joint 1.
0 is supplied. This output voltage is, for example, DC24 to DC8.
0V. Thus, the electric fusion joint 10 and the resin pipe are fused. At this time, the power supply unit 9 collects construction data (data) relating to the fusion work. The construction data includes, for example, an input voltage, an output voltage, a resistance value of a joint, a construction date and time, a conduction time, an environmental temperature, and the like. This construction data is transferred to the microcomputer unit 4 of the main control unit 3 and further transferred to the entire construction data memory area MA.
Stored. Here, the entire construction data memory area MA is
It is secured in the memory M1. The construction data stored in the entire construction data memory area MA can be read out at any time.

In the main control section 3 of the controller 1 for electric fusion joints, a memory M2 is arranged in addition to the memory M1 in which the entire construction data memory area MA is secured. The construction failure data memory area MB is secured in the memory M2. In the construction failure data memory area MB, construction data when a construction failure of the fusion work occurs is sequentially accumulated. The construction data stored in the construction failure data memory area MB can be read out at any time. Then, before the constructor performs a new fusion work, an abnormality is predicted in advance based on the past construction data at the time of the construction failure accumulated in the construction failure data memory area MB. Then, a warning is displayed on the display unit 2 of the controller 1 for the electric fusion joint, such as the content of the abnormality or the countermeasure.

A), the construction failure data stored in the construction failure data memory area MB is retrieved (b). Next, for the same type of construction failure (the same error code), those that occur N times or more and those that do not are selected (the same c). Then, for the construction failure whose number of occurrences is N or more, a maintenance recommendation and an error code are displayed on the display unit 2 (d). An example of a display on the display unit 2 is, for example, “An error code 021 has occurred three times in the past. Inspection is recommended. Press the / Confirm button to display details. ]. Next, when the confirmation button 5c is pressed (e), the contents of the recommendation are displayed on the display unit 2 (f).

According to the above-described embodiment of the warning display control, the number of occurrences of the same type of error is used as a condition for determining whether or not to display a warning (c in FIG. 2), but a time condition may be added to this. For example, a warning message will be displayed if there is a failure in the output cable three or more times within the past week, or a controller 1 for the electric fusion joint will be used.
For example, a warning message is displayed when a failure occurs at least three times within the last three months for the construction failure related to the connector contact failure of the printed circuit board.

Further, in the first embodiment, the memory M1 in which the entire construction data memory area MA is secured and the memory M2 in which the construction failure data memory area MB is secured are different memories.

First, the electric fusion joint 10 and the resin pipe are connected using a clamp (i in FIG. 5), and the barcode information of the barcode 13 is read (j).
Then, using the read barcode information as a search range (search code), construction failure data stored in the construction failure data memory area MB is searched (m in FIG. 3). Here, when it is necessary to change the search code of the bar code information, the change can be made (k and l).
An example of a display on the display unit 2 at that time is, for example, “Please select a search code. / Maker name / joint item / joint nominal diameter / joint resistance / resin name / resin wall thickness ”.

When there is construction failure data in the construction failure data memory area MB within the determined bar code information search range (the same as n), an error code is displayed on the display unit 2.
The number of occurrences is displayed as a warning (same as o). As a display example on the display unit 2, for example, “AAA BBB × CCC DD”
D / Error 021 3 times / Press the confirmation button to display details. ]. However, AAA is the joint manufacturer name, BBB is the joint item, CCC is the joint nominal diameter, DD
D is a joint resistance value.

Here, when the confirmation button 5c is pressed (the same p), the contents of the error are displayed (the same q). As an example of display on the display unit 2, for example, “Error 021 / YY-MM
-DD Vin = 95V Vo = 40V78sec / Y
Y-MM-DD Vin = 80V Vo = 38V40s
Press the ec / confirm button to display the warning content. 』
