The invention discloses a fault detection system for an optical fiber transceiver, comprising a processor, a power supply module, an interface detection module and a power-off module; the processor is respectively connected to the power supply module, the interface detection module and the power-off module, and the interface detection module is used for The initial state of each interface of the optical fiber transceiver is detected, and the detected initial state of the interface is sent to the processor, and the secondary state detection instruction sent by the processor is received, and the voltage value and current value of each detected interface are analyzed. Determine whether each interface is faulty. The invention detects each interface of the optical fiber transceiver through the interface detection module for initial and secondary state detection, effectively detects whether there is a fault in each interface, and controls the power supply module and the power-off module to stop supplying power to the faulty interface, and the system is convenient for personnel Understand the state of the interface and repair the faulty interface, which improves the detection efficiency of interface faults and reduces the continuous loss of data during long-distance data transmission.

The invention belongs to the technical field of emergency equipment, and discloses emergency equipment and methods for light modulation state information, including a defibrillator and a collection device. The defibrillator includes a power module, a main control unit, an automatic detection unit, a defibrillation unit, and a signal Modulation unit, the acquisition device includes an acquisition unit and a processing unit, the power module includes a defibrillator battery, the main control unit includes a processor, the acquisition unit includes a high-frequency signal analyzer, and the processing unit includes a single-chip microcomputer , the present invention modulates the frequency signal of the high-frequency indicator light by the controller to effectively change the use state of the indicator light, thereby realizing the simple output of the defibrillator use state signal, effectively reducing the output cost of the state information, and the high-frequency indicator light and The acquisition devices cooperate with each other, and use the high-frequency signal analyzer to complete the detection of the flickering state of the high-frequency indicator light, and cooperate with the electric telescopic rod and the warning board to realize the further display of the indicating state.

The invention discloses an electric vehicle remote control system and an electric vehicle state reporting, controlling and querying method. The electric vehicle remote control system comprises an electric vehicle and display control equipment which is in communication with the electric vehicle through a power line. When a battery of the electric vehicle is in a charging state, the electric vehicle can detect charging state of the battery of the electric vehicle in real time, demodulate communication signals on the power line, communicate with the display control equipment, modulate the charging state information of the battery into signals with the first preset frequency and then sent the signals to the display control equipment through the power line. After the communication signals on the power line are demodulated, the display control equipment is in communication with the electric vehicle, monitors and controls states of the electric vehicle in real time, and sends query commands and / or control commands to the electric vehicle through the power line. The states of the electric vehicle can be queried and controlled by the display control equipment in real time, the electric vehicle can report the states thereof to the display control equipment at any time, and accordingly the intelligent household control in true sense is realized.

The invention discloses a method for notifying user media type state information in a PoC service, comprising: A. setting the receiving or rejecting state of the first media type of the PoC user; B. after the PoC user receives or rejects the media type, the Initiating the protocol SIP message, the first media type acceptance or rejection status information is directly sent to other PoC users in the session, or the presence status information reflecting the first media type acceptance or rejection status is defined, and the presence status information is used The SIP release message is sent to the presence service server, and the presence service server sends the first media type acceptance or rejection status information to other PoC users according to the subscription of other PoC users. The present invention provides a method for notifying other PoC users of PoC session setting and state information, which can make the PoC users in the PoC session more aware of the status of each participant in the PoC session, and improve the use experience of the PoC session participants.
