Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings 1 to 2.
Safety belt monitoring device, follow the machine including control host computer and control, but the two possesses a wireless transmission module of intercommunication separately, the control is followed the machine and is included casing 1 and be located the outer safety belt buckle of casing, be provided with from machine monitoring circuit in the casing, follow machine monitoring circuit and include singlechip and rather than signal connection's gyroscope sensor wireless transmission module, the singlechip still is connected with from the machine clock module, gyroscope sensor installs on the couple of safety belt.
The utility model discloses mainly when the workman is at high altitude construction, whether the safety belt has firmly reliable hanging on the workman's health, correct operation during the use is that the operation personnel passes the safety belt buckle with the safety belt and firmly hangs, and the safety belt another firmly ties on the fixture such as building top etc. ground to wear the machine from the machine of will monitoring on one's body, open the power of the machine of monitoring and make from the normal work of machine monitoring circuit.
When workers work aloft, according to the actual state on site, the safety belt hook takes the contact part of the hook and the hanging rope as the center, the safety hook belongs to a normal state within the angle range of 85 degrees of the spatial vertical angle, and the rest angles are in a non-hanging state. The device calculates whether the safety belt hook is hung or not through the angle change of the safety hook, after the safety belt monitoring slave machine is electrified, one frame of data is sent to the safety belt monitoring host machine at a certain baud rate every 10ms, each frame of data comprises three data packets which are respectively an acceleration packet, an angular velocity packet and an angle packet, and the three data packets are sequentially output. In the invention, only the angle packet is analyzed, the FPGA/smt32 controller takes the angle packet out of each frame of data, and the data information is transmitted to the monitoring host through the wireless module, thereby realizing the remote real-time monitoring of the safety belt.
