Embodiment 1
[0063] Such as figure 1 As shown, a method for diagnosing and detecting the operating state of a drainage network is used to detect and locate abnormal operating conditions of the drainage network, including the following steps:
[0064] 1) Assemble the inspection instrument and put it into the inspection well at the starting point of the pipeline network to be inspected. After the inspection is completed, salvage and recover, read the data and preprocess the data;
[0065] The detector contains MEMS gyroscope accelerometer system, polymer lithium battery power supply system for the whole device, start-up system, GPS positioning system, SD card data collection circuit system, instrument center of gravity adjustment counterweight system, shape packaging and sealing system;
[0066] The MEMS gyroscope accelerometer system uses a high-precision gyroscope accelerometer WT61SD for the six-axis module. When debugging, it is necessary to output debugging information through the seria...
Embodiment 2
[0119] Such as Figure 5-7 As shown, a kind of drainage pipe network operating state diagnostic detector provided by the present invention includes a bottom cover 1 and a top cover 9, and the bottom cover 1 and the top cover 9 form a sealed internal space of the detector through a waterproof sealing ring 10, and the internal space It includes counterweight system, MEMS gyroscope acceleration system, starting system and polymer lithium battery 8 from bottom to top.
[0120] The counterweight system includes an eccentric counterweight 2 in the x direction and an integral counterweight 3 on the bottom cover.
[0121] The MEMS gyro accelerometer system includes a MEMS gyro accelerometer 4 and a GPS chip 5 arranged on the same SD memory card.
[0122] The MEMS gyroscope accelerometer adopts high-precision gyroscope accelerometer WT61SD, which is a six-axis module; when debugging, it is necessary to output debugging information through the serial port, connect the MEMS gyroscope ac...
