Embodiment Construction

[0019] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0020] refer to Figure 1 to Figure 5 A multi-point cascaded piezoelectric detection network for road load distribution includes a housing 1 , a flexible substrate 2 and a piezoelectric sheet 3 .

[0021] The shell 1 is a part with a hollow cuboid at the top and a threaded cylinder at the bottom. The four sides of the hollow cuboid of the shell 1 are each processed with a long hole. The flexible substrate 2 is a rectangular part made of high-strength rubber. The surface of the flexible substrate 2 is processed by one A group of circular threaded holes, a group of housing 1 and the threaded holes of the flexible substrate 2 are fixedly connected by threads, the piezoelectric sheet 3 is a rectangular part made of piezoelectric ceramics, the four planes inside the housing 1 and the four piezoelectric sheets 3 Bond and fix the connection respectively.

[0022] The method...

Abstract

The invention discloses a road load distribution multipoint cascading piezoelectric detection network and is to solve the problems that an existing method is low in efficiency, poor in precision and large in labor intensity of work personnel. The road load distribution multipoint cascading piezoelectric detection network is mainly formed by housings (1), a flexible substrate (2) and piezoelectric patches (3). The provided road load distribution multipoint cascading piezoelectric detection network is simple in structure, high in detection precision, small in accumulative error, complete in function, easy to operate, easy to install, high in versatility, low in cost and reliable in performance, and can meet road load detection requirement of the road detection industry.

Description

technical field [0001] The invention relates to a detection device in the field of road detection, more specifically, it relates to a multi-point cascaded piezoelectric detection network for road load distribution. Background technique [0002] In order to ensure the safe driving of automobiles and realize the efficiency, comfort and safety of road transportation, the measurement of road load is one of the main inspection items in the field of road inspection. At present, the measurement of the road load mainly stays in the separate measurement of the force sensor, which has low efficiency, poor accuracy and high labor intensity for the staff. The use of piezoelectric effect measurement technology to detect road loads is expected to solve the above technical bottlenecks due to its characteristics of fast, accurate and high reliability, and is of great significance for improving the measurement accuracy and automation of road loads. The invention adopts the network structure...
