The utility model relates to a remote bridge monitoring system based on Zigbee technologies. The system is characterized by comprising a displacement signal acquisition unit, a vibration signal acquisition unit and a load signal acquisition unit. Each acquisition unit is wirelessly connected with a routing node through a Zigbee module. The routing nodes are wirelessly connected with a Zigbee coordinator. The Zigbee coordinator is connected with a main control computer. The main control computer is connected with a safety supervision department. A programmable digital potentiometer serving as an adjustable resistor is further arranged in the above-mentioned signal acquisition units to achieve full-swing output of a comparator. The intelligent bridge health monitor instrument based on the Zigbee modules can achieve intelligentized monitoring and store data. After a plurality of monitor instruments form a network, wireless remote monitoring on a whole bridge can be achieved. The wiring workload can be greatly re
