The invention discloses a horizontal transportation monitoring and early warning method in concrete construction. The method comprises the following steps of step 1, carrying out scheduling information planning; step 2, identifying the state of the outlet of the mixing plant; and thirdly, enabling the concrete transport vehicle to enter the transport stage after leaving the outlet of the mixing plant, and finally enter the transfer platform. In the concrete production and transportation process, the working states of the mixing plant, the transport vehicle and the transfer equipment are effectively monitored by adopting refined and intelligent technical means and equipment, the early warning or the alarm information is sent out when monitoring indexes are about to reach or exceed an earlywarning value, meanwhile, the matching condition between planning information of the equipment is monitored in real time, and the quality accidents are avoided.
