detailed description

The present invention will be further described in detail below with reference to the embodiments and the accompanying drawings. As a limitation of the invention.

Example 1

As shown in FIG. 1 , a method for determining power supply of a base station device includes the following steps:

Step 1) Establish a power management system, where the power management system includes a monitoring center, a wireless transmission collection device, and a power supply discrimination terminal; the wireless transmission collection device transmits the collected information to the monitoring center through the wireless data channel. The wireless transmission acquisition device is a dynamic ring acquisition device or an energy consumption collection device.

Step 2) using the power management system, the wireless transmission collection device is connected to the power supply discrimination terminal, receives the power supply source and the power supply time signal of the base station device determined by the power supply determination terminal, and transmits the signal to the monitoring center through the wireless system. The software shows that the base station equipment is powered by grid power, generator emergency power generation or battery power. The power supply judging terminal discriminates that the power supply of the base station device is derived from grid power supply, generator emergency power generation or battery power supply, and records the start and end time of each power supply mode, and then transmits the status and time information of each power supply mode to the wireless transmission collection device. The monitoring center displays, according to the received power source and power supply time signal of the base station device, that the base station currently uses the mains power supply, the generator power supply or the battery power supply, and displays the start and end time of each power supply mode.

The power supply discrimination terminal determines whether the base station power supply AC input is from the grid power supply or the generator emergency power supply by comparing the AC output frequency deviation of the power grid to be smaller than the generator AC output frequency. If neither of the above two situations, the data is sent to the monitoring center. Then it is judged that the battery is powered.

The power supply discrimination terminal is connected to the power supply input end through the matching current transformer. When the current transformer detects the current, the power supply identification terminal collects the power supply frequency deviation, and sets the maximum frequency deviation of the power supply to the frequency deviation determination threshold. When the power supply discrimination terminal works normally, the power input frequency deviation of the base station equipment is collected, the power input frequency deviation is greater than the frequency deviation determination threshold, the generator is determined to be powered, and the generator power supply start and stop time is recorded, and the power input frequency deviation is less than or equal to the frequency. Deviation discriminates the threshold, determines that the grid is powered, and records the grid power supply start and stop time. If the power input frequency is not collected, it is determined that the battery is powered, and the battery power supply start and end time is recorded.

The power supply frequency between the mains and the generator is different. The mains supply belongs to the large power grid. The generator set of the power plant keeps the speed constant at 3000 rpm, so the mains power supply frequency is stable at 50±0.5HZ. When the generator belongs to the power supply individual, the generator has limited load capacity, and the change of the load current will cause the change of the rotational speed, which is impossible to stabilize. The control is controlled at 3000 rpm, so it will cause the power frequency to change to 50±1HZ or even larger. Therefore, the power supply discriminating terminal distinguishes the grid power supply, the generator emergency power generation or the battery power supply by setting the frequency deviation discrimination threshold, and displays the power supply of the base station equipment from the power grid, the generator emergency power generation or the battery power supply through the monitoring center; and records the battery Power supply start and end time.

The power supply discrimination terminal is a separate terminal, and the power supply determination terminal function module, circuit or software is added to the electric meter to complete. The electric meter with power supply discriminating function (as shown in Fig. 2), the electric energy collecting and measuring chip collects the frequency deviation of the grid power supply when the grid power supply transformer has current, and the electric meter with the power supply discriminating function collects the frequency deviation of the grid power supply for learning The maximum frequency deviation of the grid power supply is set as the frequency deviation discrimination threshold, and the power input frequency deviation of the base station equipment is collected when the power meter with the power supply discrimination function is working normally, and the power input frequency deviation is greater than the frequency deviation determination threshold, and the generator is determined to be powered. And record the start and stop time of the generator power supply, the power input frequency deviation is less than or equal to the frequency deviation determination threshold, determine the grid power supply, and record the grid power supply start and stop time, the power input frequency is not collected, determine the battery power supply, and record the battery power supply start and stop time. The result of the determination is stored in the memory by the CPU. At the same time, the electric meter with the power supply discriminating function transmits the determination result to the wireless transmission collecting device through the RS485 communication interface, and the wireless transmission collecting device can be an energy consumption collector or a moving loop collector (FSU), and the wireless transmission collecting device passes the wireless The data channel (TD_LTE/HSDPA/GPRS/EV_DO/CDMA1X) sends the power input source of the base station device and the power supply time to the monitoring center. The monitoring center displays on the software platform according to the received data content that the power supply of the base station device is the start and end time and duration of the power supply of the power grid, and the start and stop time and duration of the emergency power generation of the generator. In addition, when both types of communication are not input, the time and duration of battery power supply.

A method for judging power supply of a base station device, which can provide start and stop time and event record for power generation, facilitate power generation record inquiry, provide power generation time statistics, achieve clear purpose of clearing base station generation company's power generation cost, and provide recording materials for cost auditing and inquiry; The grid power supply and power generation records of the base station provide the basis for the later power supply and power plant transformation.
