Load control spot integrated tester

Abstract

The invention discloses a load control spot integrated tester. The load control spot integrated tester comprises a box body and a tester body located in the box body. The tester body comprises a main control unit, an input and output module, a storage battery, an inverter module, a GPRS test module, a CDMA1X test module, a 230MHz data transfer radio test module, an RS-485 interface test module, a pulse test module and an external interface. The load control spot integrated tester further comprises a lighting device, and the storage battery is connected with the lighting device. The load control spot integrated tester can detect various common external communication interfaces in an electric power load control system distribution room, therefore, adaptability is high, and detection is efficient and quick. The load control spot integrated tester can provide temporary power supply and spot lighting for devices (such as load control terminals and electric meters) in the distribution room, and the power supply part has the charging and electricity protection functions. The load control spot integrated tester is designed to a suitcase type, convenient to carry and simple in operation.

Description

technical field [0001] The invention relates to a power detection device, in particular to a load control on-site comprehensive tester used in a power load control system area, belonging to the field of power load control on-site testing. [0002] Background technique [0003] The power load control management system mainly includes the master station, power load control terminal and various electric meters (three-phase four-wire, three-phase three-wire electric meter and single-phase electric meter). The main communication methods between the main station and the load control terminal are GPRS and CDMA 1X Communicate with the 230MHz radio station, and the communication between the load control terminal and the meter is mainly through the RS-485 interface and the pulse interface. Whether the communication between the above-mentioned parts is normal or not is related to the operation efficiency of the load control management system, so it is particularly important to detect ...

AI Technical Summary

Problems solved by technology

Whether the communication between the above-mentioned parts is normal or not is related to the operation efficiency of the load control management system, so it is particularly important to detect the communication between them. However, there is currently a lack of efficient and quick tools for the detection of various communication functions. Conduct a comprehensive inspection of the interfaces of the equipment in the negative control area. The staff need to carry a variety of testing equipment such as field strength meters, oscilloscopes, RS-485 interface testers, and multimeters.

Use a field strength meter to test the wireless interface. The setting and operation of the field strength meter is cumbersome and requires certain professional knowledge. Moreover, due to the different frequency bands and modulation methods of GPRS, CDMA 1X and 230MHz radio stations, a field strength meter cannot adapt to these methods. It is necessary to choose the appropriate field strength meter according to the specific use situation, which increases the difficulty of the user

The detection of RS-485 interface and pulse interface requires the use of oscilloscopes, RS-485 interface testers and multimeters. Several detection tools need to be used alternately, and the operation process is cumbersome, which leads to complex detection and testing of the system and unsatisfactory results.

[0004] In addition, when performing temporary power outage maintenance on the negative console area, small generators are basically used to provide temporary power support for related equipment and devices. Coordination and operation greatly affect work efficiency and are very inconvenient
