specific Embodiment approach 1

[0005] Specific implementation mode one: the following combination figure 1 This embodiment will be specifically described. This embodiment consists of a GSM data transceiver module or a GPRS data transceiver module 1, a transceiver 2, an MCU controller 3, an AC contactor opening and closing drive circuit 4, an AC contactor opening and closing state detection circuit 5, and a sunlight illumination detection circuit 6. One communication end of the GSM data transceiver module or GPRS data transceiver module 1 is connected to one end of the transceiver 2, the other end of the transceiver 2 is connected to a communication terminal of the MCU controller 3, and an input end of the MCU controller 3 is connected to the sunlight detection circuit 6, the other input end of the MCU controller 3 is connected to the output end of the AC contactor opening and closing state detection circuit 5, and the output end of the MCU controller 3 is connected to the input end of the AC contactor openi...

specific Embodiment approach 2

[0006] Specific implementation mode two: the following combination figure 1 This embodiment will be specifically described. The difference between this embodiment and Embodiment 1 is that it also includes a power carrier communication interface circuit 7 , one communication end of the power carrier communication interface circuit 7 is connected to the other communication end of the MCU controller 3 . In this way, the terminal of the present invention can communicate with the single-lamp monitoring device installed on each street lamp through the low-voltage power line that supplies power to each street lamp, so as to realize real single-lamp control and fault detection, and accurately calculate the lighting rate parameters , realizing the automatic control of multi-period and multi-scenario (street lights on or off interval change and brightness change) mode according to the time control strategy table. Other composition and connection modes are the same as those in Embodimen...

specific Embodiment approach 3

[0007] Specific implementation mode three: the following combination figure 1 This embodiment will be specifically described. The difference between this embodiment and the first embodiment is that it also includes a 485 bus transceiver 8 , and one end of the 485 bus transceiver 8 is connected to another communication end of the MCU controller 3 . In this way, on the premise that each street lamp is connected to the 485 bus, the terminal of the present invention can communicate with the single lamp monitoring device through the 485 bus. Other composition and connection modes are the same as those in Embodiment 1.

Abstract

A terminal for monitoring road lamp of city consists of GSM data transmitting - receiving module or GPRS data transmitting - receiving module , transceiver , MCU controller , AC contactor open - close driving circuit , AC contactor open- close state detection circuit and sunlight illumination detection circuit . The terminal set far from road lamp management centre can realize two-way remote data transmission with said centre for achieving remote control and data refreshment of road lamp.

Description

Technical field: [0001] The invention relates to a terminal device for monitoring urban street lamps. Background technique: [0002] At present, with the continuous expansion of the city area, it is becoming more and more difficult for the municipal departments to manage street lights in streets and communities. On the one hand, the number of street lamps is increasing, and on the other hand, the distribution area of ​​street lamps is becoming wider and wider, and the increase of management units operated by people will inevitably increase the management expenses of the municipal department. Now, mobile communication technology (GSM) and wireless data transmission technology (GPRS) have been very popular. These two communication methods have the advantages of not being limited by communication distance and easy to realize multi-user distinction, providing technology for remote monitoring of urban street lights. Base. But there is no device for remotely controlling street l...
