A multi-functional sensor system for simultaneously monitoring various parameters such as the structural, chemical and environmental conditions associated with a medium to be monitored, e.g., bridges, high-rise buildings, pollution zones, is provided wherein the system includes at least a plurality of wireless multi-functional sensor platforms embedded in the medium in which an interrogation unit transmits power and receives responses. Each wireless multi-functional sensor platform includes multiple channels for accommodating a plurality of sensor types to simultaneously monitor the parameters associated with the medium. Thus, the wireless sensor platforms are formed to include those sensor types which are considered germane to the intended medium to be monitored.

The invention discloses bridge equipment. The bridge equipment comprises a base body, a frame body and an electric connector, wherein the frame body is fixedly arranged on the left upper side of the base body; an inserting groove is formed in the base body under the frame body,; a first electric connecting pin is arranged in the inserting groove; a first slide groove is formed in the end surface of the bottom of the right side of the frame body; a locking part is arranged in the first slide groove; a first stud, which is connected with the locking part in a screw-thread fit manner and extends to the left side and the right side, is arranged in the first slide groove; a first slide cavity is formed in the base body on the right side of the frame body; a communication groove is formed between the first slide cavity and the first slide groove; a first hollow cavity is formed in the base body above the communication groove; a second groove bottom is arranged in the frame body above the right side of the first slide groove; a second slide groove, which runs through the top wall of the frame body, is formed in a position, above the second groove part, in the frame body; a pushing and pressing rod, which is arranged oppositely to the left side end of the communication groove, is arranged on the end surface of the right side of the locking part; a slide block is connected in the first slide cavity in a loose fit manner. The bridge equipment disclosed by the invention has the advantages of simple structure, convenient inserting, automatic locking and inserting, and has an intelligent prompting function.

Described herein are wireless interrogation systems and methods that rely on a complementary sensing device and interrogator. The sensing device is disposed to measure a parameter indicative of the health of a structure. A sensor reading from the sensor indicates the level of a parameter being monitored or whether one or more particular physical or chemical events have taken place. Using wireless techniques, the interrogator probes the device to determine its identity and its current sensor reading. This often includes transmission of a wireless signal through portions of the structure. When activated, the device responds with a wireless signal that identifies the device and contains information about the parameter being measured or a particular sensor state corresponding to the parameter. The identity of the device allows it to be distinguished from a number of similar devices. Thus this invention finds particular usefulness in the context of an array of devices that can be probed by a wireless interrogation unit. In one embodiment, the devices are passive and derive power from the interrogation signal.
