[0055] Embodiment 1:

[0056] like Figure 1 As shown, the present disclosure provides a dynamic environment alarm device for a communication base station, the device comprising:

[0057] A direct current DC / DC conversion module 1 is used to connect to the battery of the communication base station, convert the first DC of the battery of the communication base station into a second DC, and provide the second DC for the voltage detection control board 2;

[0058] Voltage detection control board 2, including:

[0059] The first voltage detection unit 22 is used to detect a first DC voltage of a switching power supply system of the communication base station, and in response to the first DC voltage being lower than a first threshold, issue a city power failure alarm signal.

[0060] The second voltage detection unit 23 is used to detect a second DC voltage of the battery of the communication base station, and send a battery low voltage alarm signal in response to the second DC voltage being lower than a second threshold.

[0061] In this embodiment, the battery of the communication base station is used to provide a DC power supply for the dynamic environment alarm device, and the two DC voltages of the base station are used to detect the base station power outage and battery low voltage alarm respectively. There is no need to use and detect AC power, so that the device has low energy consumption, simple structure, low cost and small size.

[0062] More specifically, due to the rapid development of my country's communications industry, the scale of the communications network has continued to expand, the number of communications bureaus (stations) has increased, and there are a large number of unmanned communications bureaus (stations), such as mobile base stations, access networks, fixed-line module bureaus, optical cable relay stations, etc. Various types of integrated communications buildings must also gradually achieve less-staffed and unmanned operations. Mobile base stations have been unmanned due to their large number and scattered sites. The base station room environment is the basis for ensuring the safe and stable operation of the communication system. Therefore, the maintenance of power equipment must be timely and reliable to ensure the normal operation of the communication system. Generally, a dedicated dynamic environment monitoring system is built.

[0063] In view of this, this embodiment proposes a solution with low investment, low operating cost and high site space utilization for operators in base station dynamic environment monitoring. The dynamic environment alarm device provided uses DC power supply as operation input, DC (Direct Current) 36-72V wide voltage input, working current is less than 40mA (DC48V), power consumption is less than 2W, the device uses DC power supply to avoid abnormal external market of the base station to burn out the board, the electrical system is stable, the average service life is up to 50,000 hours, and the base station battery DC power is used to eliminate the need for batteries. The shell of this dynamic environment alarm device can be made into a box of about 18cm*11.5cm*4.4cm in size, and each set of equipment costs about 250 yuan.

[0064] The base station mains power outage is realized by detecting the voltage (analog quantity) of the base station switch power supply system. When the alarm device detects that the input DC voltage is lower than 52.0V (adjustable), the relay outputs a power outage alarm switch signal; the low voltage alarm is to detect the system backup battery power supply after the mains power outage. When the alarm device detects that the input DC voltage is lower than 48.0V (adjustable), the relay outputs a low voltage alarm switch signal. The working current and detection current used by the device are the output current of the original battery of the base station, and there is no need to connect to the mains or install a backup battery for the device.

[0065] In one embodiment, the device further comprises:

[0066] Breakout board 4, including:

[0067] The first multi-channel high-low level relay module 41 is connected to the first voltage detection unit 22 and is used to divide the mains power failure alarm signal into multiple channels.

[0068] A second multi-channel high-low level relay module 41 is connected to the second voltage detection unit 23 and is used to divide the battery low voltage alarm signal into multiple channels;

[0069] The signal shunt regulating resistor 5 is connected to the input terminal 11 of the DC / DC conversion module, the first voltage detection unit 22 and the second voltage detection unit 23, and is used to use the first DC to control the mains power failure alarm signal and the battery low voltage alarm signal to meet the signal output requirements divided into multiple channels.

[0070] In this embodiment, the alarm signal is divided into multiple outputs. At the same time, in order to meet the requirements of multi-channel signal output, a signal shunt adjustment resistor 5 is added. The signal shunt adjustment resistor 5 is powered by the first DC, and through the connection relationship and resistance design, the mains power outage alarm signal and the battery low voltage alarm signal are adjusted to meet the requirements of divided into multiple signal outputs.

[0071] More specifically, as the base stations of various operators in my country are uniformly transferred to the tower company, and the supporting assets of the site power equipment are assigned to China Tower, the tower company has transformed the original power environment (power outages, high temperatures, etc.) alarm system of the base station, and switched the dynamic environment monitoring to the tower company for monitoring and use. As a result, the operator to whom the site originally belonged cannot directly view and judge the dynamic environment of the base station, affecting the operator's collection of network data and prediction of network operation assurance. The original dynamic environment alarm device of the base station can only meet the needs of one operator to directly collect and obtain the dynamic environment information of the base station. Due to the current situation that multiple operators share the site, it is impossible to achieve a single dynamic environment alarm device to meet the needs of multiple operators to directly obtain the dynamic environment information of the base station.

[0072] In view of this, the dynamic environment alarm device provided in this embodiment can have at least 3 output interfaces for power outage, low voltage, and high temperature alarms, and the outputs are connected to the external alarm interface of the base station equipment without the need for an additional communication module. The branch board 4 contains a multi-channel high and low level relay module 41 with 1 input interface corresponding to 3 output interfaces. The output signal requirements have been calculated through the combination of R1 and R2 resistors. Each alarm signal can correspond to multiple multi-channel high and low level relay modules 41, and each multi-channel high and low level relay module 41 is divided into a combination of 3 branches of one signal. The device adds a small alarm box to the base station without changing the line. As long as the DC power supply line is installed, the output alarm dry contact signal can be directly connected to the base station equipment, and the output interface is divided into 1 and 3, so that 1 dynamic environment alarm device can be realized without a backup battery, and can still normally collect and send sufficient alarm information, and meet the needs of 1 to 3 operators to directly obtain the dynamic environment information of the base station.

[0073] In one embodiment, the device further comprises:

The DC / DC conversion module 1 provides the second DC for the temperature detection control board 3, and the third multi-channel high and low level relay module 41 of the branch board 4 divides the high temperature alarm signal into multiple channels.

[0076] In this embodiment, the DC / DC conversion module 1 is used to convert the 48V voltage input by the interface board 6 into a 12V voltage (the detection voltage is also used as the working voltage, 48V and 12V are the voltages required by the internal devices); and to supply power to the 12V (internal device working voltage) DC interface of the voltage detection control board 2 (the 12V positive and negative interfaces of the power input terminal 21 of the voltage detection control board) and the 12V (internal device working voltage) DC interface of the temperature detection control board 3 (the 12V positive and ground interfaces of the input and output connection terminals 31 of the temperature detection control board).

[0078] The alarm principles include: high temperature alarm detects the room temperature through an external temperature sensor and compares it with the set temperature (adjustable), and an alarm is issued when it exceeds the set value by 0.1℃, and 0.1℃ ensures timely alarm; power outage alarm detects the switching power supply system voltage (analog quantity) and compares the voltage through an integrated circuit. If it is lower than 52.0V (adjustable), it is judged as a power outage and an alarm is output. When the switching power supply system voltage is under normal AC power supply conditions, the output power supply is 53.5V-54.0V. When the AC power is cut off, the power supply voltage immediately drops below 52.0V; low voltage alarm is that the system is powered by a backup battery, the DC voltage slowly drops, and the voltage drops below 48.0V (adjustable), and the voltage is compared and an alarm is output through an integrated circuit.

Testing the battery voltage can tell whether the power outage and battery power are about to run out, so the base station battery can be used to provide working and test currents; after a power outage, as long as the battery is not exhausted, the device can detect it, and there will be a low voltage alarm before the battery runs out.
