Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an integrated control system for an asphalt plant for producing an asphalt mixture which is a road paving material.

[0002]

2. Description of the Related Art An asphalt plant is constructed as shown in FIG.

Reference numerals 1a to 1d are aggregate hoppers for storing aggregates for each type, and the amount of cut out aggregates can be increased or decreased by variable speed feeders 2a to 2d. The type of asphalt mixture to be shipped, Each aggregate hopper 1 according to the composition
A predetermined amount of aggregate is cut out from a to 1d, and is introduced into the dryer 5 which is an aggregate heating device through the pull-out bellcon 3 and the weighing conveyor 4.

While passing through the dryer 5, it is heated to a predetermined temperature by the hot air of the burner 6, and the heated aggregate is lifted up to the upper part of the plant body by the bucket elevator 7 and supplied to the vibrating sieve 8 and the vibrating sieve 8. The heated aggregate supplied to 8 is sieved according to particle size and stored in each compartment of the aggregate storage bin 9 according to particle size.

When there is a request for shipment of the asphalt mixture, aggregates of various particle sizes are dispensed from the aggregate storage bin 9 to the aggregate measuring tank 10 based on the mixture of the asphalt mixture to be produced, and the aggregates are respectively weighed. The stone powder stored in the stone powder storage tank 13 via the stone powder elevator 12 is weighed and input in the stone powder measuring tank 14, and further the asphalt measured in a predetermined amount in the asphalt measuring tank 15 is injected. The asphalt mixture is manufactured by kneading and is shipped to the construction site or the like by the carrier 16.

[0006] In order to maintain the performance of the asphalt plant and to always ship high quality asphalt mixture, the asphalt plant is comprehensively managed in terms of operation status, maintenance, shipping status, cost and the like.

The operation status is managed by the operator reading the operation information of each device of the plant from the instruments such as the operation panel and the power panel, and creating and managing the ledger concerning the operation status from the daily report reported by the operator. There is.

Further, the maintenance management prepares a maintenance ledger based on the report of the daily inspection by the operator, and judges the replacement, repair and adjustment time of the equipment and parts by the ledger.

Further, the management of the shipping status is performed by printing out the measurement data of the material for each material and totaling the usage fee of the material,
The shipping records are artificially aggregated to grasp the shipping status for each builder and each composition.

Further, in cost management, a cost management ledger is created by artificially totaling the amount of each material used, fuel consumption, power consumption, etc., and costs are calculated based on this ledger. It manages.

[0011]

[Problems to be Solved by the Invention] However, even if the asphalt plant is comprehensively managed, there are many cases in which operation information is collected and a management ledger is created exclusively by humans. Timely collection of comprehensive management data on plant operation such as suitability of plant operating conditions, quality of materials and products used, maintenance time, etc. due to omissions in collection and time-consuming preparation of various management data Sometimes it cannot be created.

In view of the above points, the present invention aims at speeding up and labor saving in creating comprehensive management data of a plant by collecting operation information of the plant and automatically creating various management data of the plant. It is an object of the present invention to provide a comprehensive management device for an asphalt plant.

[0013]

In order to achieve the above object, the present invention connects an operation information collecting interface for collecting plant operation information to an operation panel of an asphalt plant for producing an asphalt mixture, and further operates the operation panel. It is characterized in that a plant management computer is connected to the information collection interface, and the plant management computer is provided with a comprehensive management means for outputting various plant management materials from the operation information.

[0014]

According to the integrated management apparatus for asphalt plant of the present invention, the operation information collection interface automatically collects the operation information of the plant from the operation panel of the asphalt plant, and further manages the plant based on the operation information. Comprehensive management means equipped in the computer automatically creates comprehensive management data for the plant regarding operating status, maintenance, shipping status, cost, etc. As a result, it is possible to speed up and save labor in creating the comprehensive management data of the plant.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment in which a plant management device is connected to an asphalt plant. An operation panel 21 for operating the asphalt plant 20 has an operation information collection interface 22 for collecting operation information of the plant. The operation information collecting interface 22 is connected and includes a control unit 23 including a microcomputer, a mass storage device 24, and a communication interface 25.
