技术领域technical field
本发明涉及测试技术领域,特别是涉及一种测试系统及测试方法。The invention relates to the technical field of testing, in particular to a testing system and testing method.
背景技术Background technique
钢筋混凝土广泛应用于隧道、楼宇、桥梁等各种结构中,对于这些大型结构进行定期监测可以大大降低因其崩坏而产生的生命财产损失。而在大型自然灾害比如洪水、地震、台风过后对结构进行针对性的检查也是非常有必要的。目前,可以将无源传感器嵌入混凝土中,以使混凝土传感器有效地监测混凝土的温度、湿度、受力变化、钢筋的移位和腐蚀等参数,并且,其具备成本低、实时、高效等优点。Reinforced concrete is widely used in various structures such as tunnels, buildings, bridges, etc. Regular monitoring of these large structures can greatly reduce the loss of life and property caused by their collapse. It is also necessary to carry out targeted inspections on structures after large-scale natural disasters such as floods, earthquakes, and typhoons. At present, passive sensors can be embedded in concrete to enable concrete sensors to effectively monitor parameters such as temperature, humidity, stress changes, steel bar displacement and corrosion, etc., and it has the advantages of low cost, real-time, and high efficiency.
这里,混凝土传感器在生产过程中也需要进行测试、校准等,以确保其准确性。现有的测试方法为:将混凝土传感器、供能通信设备以及笨重的混凝土模型放挪到空旷的场地,模拟实际工作场景进行供能距离测试。但,此测试方法需要较多的人力进行测试设备的挪移,导致测试效率低下;并且,在空旷的场地进行测试时地面会反射的电磁波会影响测试结果,导致测试结果准确性低。Here, the concrete sensor also needs to be tested, calibrated, etc. during production to ensure its accuracy. The existing test method is: move the concrete sensor, energy supply communication equipment and bulky concrete model to an open field, and simulate the actual working scene to test the energy supply distance. However, this test method requires a lot of manpower to move the test equipment, resulting in low test efficiency; moreover, when testing in an open field, the electromagnetic waves reflected by the ground will affect the test results, resulting in low accuracy of the test results.
因此,亟需一种测试方法来检测混凝土传感器。Therefore, there is an urgent need for a testing method to detect concrete sensors.
