The invention discloses a remote real-time monitoring method of a big-
bus operating status, fuel consumption and
exhaust gas emission. The remote real-time monitoring method comprises the following steps: an online communication model is established between a
server and a
wireless communication module; user request information
forms control instructions by the
server, and the control instructions are transmitted to the
wireless communication module through a
router, an internet and a
wireless network after being encrypted, and the encrypted control instructions are transmitted to a
bus information acquisition unit through the wireless communication module; the encrypted control instructions are decrypted by the
bus information acquisition unit, the big-bus operating status, and the fuel consumption and
exhaust gas emission data are acquired from the CAN (Controller
Area Network) bus of the big bus and processed, and the real-
time data is encrypted and transmitted to the wireless communication module; the encrypted real-
time data is transmitted to the
server through the wireless communication module and decrypted through the server, the decrypted data is processed and accessed by the
client of the user. The
monitoring system comprises the server, the
router, the wireless communication module installed on the big bus, the big-bus
information acquisition unit and the power supply module.
