The invention discloses a distributed mine earthquake detection method and device and relates to the field of underground coal mine safety monitoring. The distributed mine earthquake detection method comprises the steps that multiple channels of quake detection devices are arranged on a device or area to be detected in a distributed mode; after a server provides a starting signal, high-accuracy synchronous quake detection begins to be performed, and the acquired signal is received and processed by devices and transmitted to the cloud server through the Ethernet; the server performs data fusion analysis processing on mass information and then provides the processed information for users. Hardware of the distributed mine earthquake detection device comprises a quake detection and conversion unit, a microcontroller unit, a human-computer interaction unit, a storage unit, a communication unit, a time synchronous unit and the server. The distributed mine earthquake detection method and device has the advantages that quake signals with high sensitivity and a large dynamic range can be detected, frequency response characteristics are wide, data can be transmitted quickly in a nondestructive mode, networked synchronization and focus positioning accuracy under a distributed environment is high, and the system is high in capacity, strong in expansion capability and low in expansion cost.

The invention provides a layout optimization method for video monitoring in a chemical plant area. Factors such as monitoring of a whole chemical plant area, monitoring of a key dangerous area and monitoring cost are comprehensively considered; for the global monitoring of the chemical plant area and the key monitoring problem of the dangerous operation link, the optimization of the overall layoutof the video monitoring equipment is carried out, and the monitoring requirements of the whole chemical plant area and the key dangerous operation link can be met at the same time. According to the layout optimization method for chemical plant area video monitoring, cost factors of chemical plant area video monitoring layout are considered according to the monitoring target optimization function,optimization calculation is carried out by adopting a random particle swarm intelligent algorithm, and a layout scheme which meets the chemical plant area monitoring requirement and has the lowest cost and the strongest monitoring capacity can be provided.

The invention relates to a PSM digital circulation controller, in particular to a PSM digital circulation controller based on an FPGA (Field Programmable Gate Array) and a control method thereof. The controller comprises an audio signal processing unit, a control unit and an M bit shift register, wherein the audio signal processing unit, the control unit and the M bit shift register are built from the FPGA, the audio signal processing unit equally divides audio signals according to the time and converts the audio signals into direct current superposed audio signals to be sent to the control unit, the output of the control unit is connected with the M bit shift register, and the control unit controls the M bit shift register according to a time sequence and a direct current superposed audio signal amount to send closing and opening signals of a control switch module of 1 or 0 according to sequences of closing and opening firstly as well as opening and closing firstly. The PSM digital circulation controller is realized by adopting the FPGA through a software, has high signal processing accuracy and is realized by using a software algorithm to replace hardware, thereby enhancing performance indexes of a launcher, miniaturizing a hardware system, enhancing the system reliability and being beneficial to upgrading and networking the system.
