Description

Technical Field

[0001] The utility model relates to the technical field of energy storage power, and in particular to a testing device for power supply equipment of a communication base station. Background Art

[0002] In the construction of communication base stations, the machine room and the tower mast are two very important components. The machine room needs to be efficient, safe and reliable to ensure the normal operation of communication equipment. The tower mast needs to be reasonably designed and constructed according to different geographical environments, climatic conditions and other factors to ensure that it can withstand the corresponding loads and natural forces such as wind.

It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0017] The utility model aims to provide a testing device for power supply equipment of a communication base station in view of the defects of the prior art.

[0018] Embodiment 1

[0019] This embodiment provides a testing device for a power supply device of a communication base station, such as Figure 1 As shown, it includes a control module 1, a power supply device 2, a battery pack 3, an electronic load meter 4, a DC bus 5, a switching power supply 6, an intelligent gateway 7, and a cloud server 8.

[0020] The model used by the power supply device 2 is the Shenzhen Fuguang SFE-S series main control; the battery pack is a battery pack formed by 22 2V500AH batteries connected in series; the model used by the electronic load meter 4 is Fuguang FEFD-60300; the DC bus 5 is the intersection of the power lines and is named bus on the base station; the model used by the switching power supply 6 is Huawei MU48 series monitoring module or Zhongheng Electric SMU01 monitoring equipment; the intelligent gateway 7 and the cloud server 8 can all use existing equipment, which is not limited in this embodiment; the control module 1 is an existing host computer with a display, that is, an existing ordinary PC, desktop or notebook can be used, requiring Windows 10 and above systems, and having a wireless network card and a USB interface; the computer runs an existing DCDC monitoring platform.

[0021] It should be noted that the control module 1 of this embodiment can be an existing device, and this embodiment does not require any improvement thereto.

[0022] The control module 1 is connected to the power supply device 2 (bidirectional DC / DC) and the intelligent gateway 7 respectively through the USB to 485 module. Specifically, the USB interface of the control module 1 is connected to a USB to 485 module, and then the converted 485 is connected to the power supply device 2 (bidirectional DC / DC) and the intelligent gateway 7. Through the USB to 485 module, the computer is equivalent to an external 485 serial port device; the model of the USB to 485 module is Yutai UT-890A.

[0023] The control module 1 is also connected to the electronic load meter 4 via wifi; the wireless network card of the control module 1 is used to connect to the WIFI hotspot of the electronic load meter 4, thereby establishing a TCP communication connection.

[0024] The power supply device 2 is electrically connected to the battery pack 3 and the DC bus 5 (voltage is 56.4V) respectively, and the electronic load meter 4 is also electrically connected to the DC bus 5; one end of the switching power supply 6 (AD / DC) is connected to 220V AC power, and the other end is connected to the DC bus 5; the intelligent gateway 7 is also communicatively connected to the cloud server 8.

[0025] In this embodiment, the direction of electric energy is as follows: the electric energy of the battery pack 3 is transmitted to the power supply device 2 , and the electric energy of the power supply device 2 reaches the electronic load 4 after passing through the DC bus 5 .

[0026] In this embodiment, the electronic load meter 4 plays a role in simulating the communication equipment in the base station under actual working conditions. When the battery pack 3 is in a discharging state, the electronic load meter 4 is turned on by the control module 1. When the battery pack is in a non-discharging state, the electronic load meter 4 is turned off by the control module 1. This device produces economic benefits and saves the electric energy consumed in the test. The saved electric energy is reflected in the energy saved when the electronic load is turned off.

[0027] In this embodiment, the battery pack is charged for 5 hours and discharged for 5 hours a day as an example. If the electronic load meter is not controlled, the electronic load will be in the on state for 24 hours a day. With the electronic load 4KW power meter, the power consumption is 96KWH. After the electronic load meter is constructed to switch on and off, the electronic load meter is only turned on for 5 hours, and only consumes 20KWH a day, which can save 76KWH of electricity a day.

[0028] From the perspective of test effectiveness and actual simulated working conditions, if the on / off function of the electronic load meter is not constructed, either the electronic load is always turned on, wasting energy, or a corresponding person turns the electronic load on and off according to the actual discharge time. For example, in a certain province, there is a valley electricity price period from 15:00 to 22:00. At this time, the battery pack needs to be discharged, and the electronic load needs to be turned on at 15:00, and it needs to be turned off manually at 22:00. Otherwise, it will waste energy until the person goes to work the next day to perform the turn-off operation. The use of the device of this embodiment can save energy and labor costs.

[0029] In the present embodiment, under actual working conditions, the bidirectional DC / DC 2 sends the collected data, including voltage, current, temperature, power, electric energy value, etc., to the cloud server 8 through the intelligent gateway 7, and the panel of the bidirectional DC / DC 2 can also display part of the data. In the communication between the bidirectional DC / DC 2 and the intelligent gateway 7, the data communication bus uses the 485 communication method based on the Modbus / RTU protocol. In the test device of the present embodiment, the control module 1 leads the USB to 485 module to the communication line between the bidirectional DC / DC 2 and the intelligent gateway 7, and then monitors all the data communication messages on the 485 bus, obtains the expected voltage, current and other data according to the monitored messages, and saves the data to the local file. Taking actual working conditions as an example, the existing intelligent gateway is connected to the cloud server through the 4G network. Each uplink and downlink of data consumes the traffic of the traffic card. Therefore, the faster the communication frequency, the more traffic, and the more traffic fees are consumed. Therefore, the communication frequency between the intelligent gateway and the cloud server is about once every 15 minutes. However, in the two-way DC / DC equipment testing process, this frequency is obviously not enough, and some key point data cannot be effectively captured, and key samples are easily missed. With the device of this embodiment, the intelligent gateway and the two-way DC / DC main control and control module are on a 485 bus. This bus is local data communication and does not involve traffic fees. Its communication frequency is relatively high, about once every 1S. This device uses the monitored data to capture key point data in a timely and effective manner and record it, which is of great significance for the later equipment maintenance and the testing of two-way DC / DC equipment.

[0030] Compared with the prior art, the test device of the utility model saves the electric energy and manpower cost consumed in the test by switching the electronic load meter on and off.

[0031] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
