Method of communication between construction equipment and management server
First Claim
1. A communication method between construction equipment and a management server, comprising:
- (i) receiving, by a diagnostic device of the construction equipment, state information from a plurality of vehicle control devices;
(ii) checking for, by the diagnostic device, a usable communication method when the received state information is identified to be transmitted to the management server;
(iii) when there is one usable communication method identified by the checking, transmitting, by the diagnostic device, the state information to the management server using the one usable communication method; and
(iv) when there is a plurality of usable communication methods identified by the checking, selecting, by the diagnostic device, a communication method from the plurality of usable communication methods having the lowest fee per unit data, and transmitting the state information to the management server using the selected communication method,wherein the diagnostic device of the construction equipment periodically monitors respective location information and charging policies of communication network providers using the operations (i), (ii), (iii), and (iv).

5. A diagnostic device of construction equipment, comprising:
-
a CAN interface configured to perform CAN communication with a plurality of vehicle control devices included in the construction equipment; a GPS configured to provide location information on the construction equipment;
communication circuitry including a near field communication device, a mobile communications device, and a satellite communication device configured to transmit state information on the vehicle control devices to a surrounding communication terminal or a management server;a memory configured to store the state information received from the plurality of vehicle control devices, and a satellite communication fee when the satellite communication device is used; and a controller configured to; request the state information from the plurality of vehicle control devices; receive the state information; and transmit the received state information to the surrounding communication terminal or the management server, wherein the controller requests a check of a first mobile communication fee when the mobile communications device transmits current location information on the construction equipment to the management server, requests a check of a second mobile communication fee from the surrounding communication terminal when the surrounding communication terminal is used, and selects a communication method having the lowest communication fee among the first mobile communication fee, the second mobile communication fee, and a pre-stored satellite communication fee.
