Problems solved by technology

Assuming that at a certain moment, transmitter A detects an object and transmits a signal to turn on the light, and after transmitter A transmits 5ms, transmitter B detects the object and transmits, but transmitter B 800 meters away cannot know that transmitter A is transmitting, So he will also transmit signals, then the superimposed part in the middle of them will not be able to receive signals accurately, and will interfere with each other

Embodiment 1

[0047] see figure 1 , The present invention discloses a wireless control system for intelligent street lamps. The system includes several node units 10, and each node unit 10 includes: a controller 11, a time synchronizer 13, and a wireless device.

[0048] 【Time Synchronizer】

[0049] The time synchronizer 13 is used to synchronize the time of the node units 10, so that all the node units 10 in the entire system are time synchronized and the system time is unified. The time synchronizer 13 realizes time synchronization through satellite timing; or, the time synchronizer realizes time synchronization through mobile phone base station timing.

[0050] 【Wireless device】

[0051] The wireless device includes a wireless receiver 15 or / and a wireless transmitter 14; the wireless receiver 15 is used for receiving wireless signals, and the wireless transmitter 14 is used for sending wireless signals.

[0052] 【Controller】

[0053] The controller 11 is connected to the time synchron...

Embodiment 2

[0069] The system includes several street lamps, and each street lamp is equipped with a gps time synchronizer, a wireless transceiver, and a sensor. The gps satellite system is used for second synchronization, and the time period is set as 1s. And divided into 10 equal parts, respectively 0s, 0.1s, 0.2s, 0.3s, 0.4s, 0.5s, 0.6s, 0.7s, 0.8s, 0.9s. It is stipulated that 0s is the starting signal point, 0.1s-0.5s is the signal forwarding point, 0.6s is the forwarding end point, 0.7s is the signal point for turning on the light, 0.8s is the signal point for turning off the light, and 0.9s is used for fault broadcasting. The forwarding algorithm is sequential and forwarded within the same second. The starting signal point transmits 0x55, the forwarding signal point transmits 0xAA, the light-on signal is 0x01, and the light-off signal is 0x02. After any street light detects a person or vehicle, it will send a signal 0x55 at time 0s. After receiving the 0x55 or 0xAA signal, other li...

Abstract

The invention discloses an intelligent street lamp wireless control system and a method thereof. The system comprises a plurality of node units including synchrotimers, wireless devices, and controllers. The synchrotimers are used for carrying out time synchronization on the node units so as to enable time of all the node units of the system to be synchronized. The wireless devices consist of wireless receivers and / or wireless emitters. And the controllers are used for controling the wireless receivers to send wireless signals. The system uniformly sets emission time points of wireless signals in a period as well as sets emission contents or emission types of all the emission time points; and the different wireless signals are distinguished by the different emission time points. According to the invention, a transmission distance of a signal is substantially extended by a forwarding relay and an effective distance of a system signal can be improved. Besides, a current mode of single emission by one machine is changed into a mode of multiple emission by multiple machines, so that the stability of the system can be substantially improved and anti-interference capability can also be substantially improved; and moreover, emission time and emission contents are uniformly regulated, so that accurately synchronized and parallel operation of system signals can be realized.

Description

technical field [0001] The invention belongs to the technical field of wireless control, and relates to a street lamp control system, in particular to an intelligent street lamp wireless control system; at the same time, the invention also relates to a control method of the above-mentioned intelligent street lamp wireless control system. Background technique [0002] As a part of life, street lights are closely related to people's lives, and they are always with people's lives. It has also become a big energy consumer. According to preliminary estimates, the country's annual electricity bills on street lamps amount to tens of billions, and the consumption is astonishing. According to estimates, there are very few pedestrians and vehicles on the road after 10 o'clock in the middle of the night in small and medium-sized cities, after 12 o'clock in the middle of the night in general cities, and after 2 o'clock in the middle of the night in large and medium-sized cities. Turnin...
