The invention provides a data acquisition control unit based on a rail transit test bench, comprising a control cabinet, the control cabinet including a CPU board and a first number of first collection control boards and a second number of second collection control boards; the CPU board The card includes first and second processors, the first acquisition control board synchronously acquires the analog signals of multiple channels, and obtains the data corresponding to the analog signals of each channel, and the data corresponding to the analog signals of multiple channels constitutes The first data, after verifying the first data, obtains the first verification result, processes the first data and the first verification result into a differential signal and sends it to the first processor, and the first processor converts the differential signal After converting to a single-ended signal, the second data and the first verification result are obtained, and the second data is verified to obtain the second verification result, and the first and second verification results are compared, and the comparison is consistent After that, it is sent to the second processor for packaging and uploading to the application layer.

The invention relates to the field of intelligent monitoring, in particular to a method and system for remotely monitoring fire-fighting equipment. The present invention monitors the fire-fighting equipment in the same building by using the fire-fighting control host, obtains the alarm information and fault information sent by the fire-fighting equipment, and forwards the alarm information and fault information to the controller in the building in real time, and the controller transmits the The alarm information and fault information are forwarded to the printer and the cloud server, and the cloud server can receive the alarm information and fault information sent by the fire control hosts in various buildings in a wide range, so as to realize the network monitoring of a wide range of fire protection equipment.

The invention relates to a high-data-rate transmission system of a scene-monitoring air traffic control radar. The system comprises an optical fiber transmission system and a kilomega network system wherein the optical fiber transmission system comprises a digital receiver, an optical amplifier, an optical acquiring card and a computer; the kilomega network system comprises a digital receiver, an exchanger and a computer; the optical fiber transmission system is used for transmitting an original echo data signal of the radar unidirectionally; the kilomega network system is used for directionally transmitting data signals excluding the original echo data signal of the radar. The system disclosed by the invention adopts a method that optical fibers are combined with a kilomega network and is also matched with an optical power divider having an amplification function, a four-way high-speed optical acquiring card and a computer having a high-speed storage function. Effective high-data-rate transmission is guaranteed, and the reliability of the system is improved as well due to an interaction mode of mutual duplication of the computers.

The invention relates to a long-distance rapid replacing type supporting roller mechanism, and specifically relates to a long-distance rapid replacing type supporting roller mechanism which is suitably used for supporting a disc shaped part soaked in high-radioactive liquid. The supporting roller mechanism comprises a plurality of roller bodies which are symmetrically mounted like an arc on a mounting plate, wherein each roller body comprises a front end, a medium end and a tail end; a flexible rotating roller is mounted at each front end and used for supporting the disc shaped part; each tail end passes through a circular hole in the mounting plate and is fixed to the mounting plate through a locking assembly. With the adoption of the supporting roller mechanism, the disc shaped part can be reliably supported, and moreover, the long-distance maintenance, overhaul and replacement can be conveniently and quickly performed for the disc shaped part through a manipulator or a power hand.

The invention discloses a failure detecting method and device, able to be applied to intelligent network, where the intelligent network includes service control points (SCPs). And the method includes: a) obtaining interactive information between the SCP and other device from the SCP; b) according to the obtained information, searching the reason for failure. The device comprises intercepting module and detecting module, where the intercepting module is arranged at the SCP to obtain the interactive information; the detecting module is connected with the intercepting module to search the reason for failure according to the interface information obtained. As compared with existing techniques, it is simple to operate, easy to apply and only needs to operate fewer SCPs, and convenient to maintain, and able to reduce the effect on SCP operation as far as possible.

The invention discloses a rapidly deployable mobile application and network service integration testing device, which includes a software system that completes the coordinated work of the entire system and a hardware system that realizes remote control according to the instructions of the software system; the hardware system includes: collecting data according to the APP Multiple mobile phone motherboards, embedded master controller for management according to signal instructions, Linux industrial computer, wireless gateway module and power management module; the software system includes: (1) Embedded control software installed on the embedded master controller (2) the management APP installed on the main board of the mobile phone; (3) the APP application software installed on the administrator's mobile phone; (4) installed on the Linux industrial computer; The test equipment can independently complete the comprehensive test work when it has a power supply, and the deployment personnel are no longer required to master relevant professional skills, which greatly improves the deployment efficiency and business of business models that require distributed management of a large number of mobile phones, such as APP performance testing and mobile network environment testing. Work efficiency, greatly reduce management and maintenance costs, and improve the effectiveness and flexibility of the test environment.

The invention relates to a monitoring system of an aircraft guidance process and a monitoring method thereof. A monitoring system for the guidance process of an aircraft, which is used to monitor the docking process of the aircraft along the guidance line of the parking area through the guidance information display screen of a visual guidance system, including an image acquisition module, an image integration unit, and a monitoring screen and video recorders. The image acquisition module has a first camera for capturing the docking process of the aircraft to obtain a docking dynamic image, and a second camera for capturing images of the guidance information display screen to obtain a guidance information dynamic image. The image integration unit integrates the docking dynamic image and the guidance information dynamic image into a synchronously presented and adjacent integrated image. The monitoring screen receives and displays the integrated image. The video recorder records the integrated video. The invention also provides a monitoring method for the aircraft guidance process.
