Description

Environmental Monitoring System Field of the Invention The present invention relates to an environmental monitoring system, specifically referring to an environmental monitoring system capable of monitoring the surrounding environmental condition of each light fixture by a remote host. Background of the Invention The electric light today might be regarded as the most widely used photoelectric technology and also one of the greatest inventions of mankind; as well known, general lighting fixtures can be usually installed inside and outside of a building or be portable for use; moreover, they can be turned on or off easily by users upon actual requirements while being connected to an appropriate power source and configured with corresponding circuit switches. Most government departments prefer to arrange streetlights on both sides of roads or public areas like a park in order to improve the safety of driving or walking at night; locations for arranging streetlights may include both a fully open outdoor environment and a enclosed or semi-enclosed environment in which different operation modes may have to be set for these streetlights. For instance, a tunnel belongs to a kind of semi-enclosed environment and is different from the roads at the entrance and exit ends of the tunnel; because of no sunlight being received inside the tunnel usually, the light fixtures arranged in the tunnel are almost set in a fulltime operation mode so as to ensure the walking and driving safety. Furthermore, lighting fixtures like streetlights are mostly arranged in remote locations and widely distributed; therefore, controlling circuits for turning on or off the streetlights automatically may usually be further arranged to improve the convenience of operating the streetlights; the automatic controlling circuits employed for such streetlights are usually set to a control mode in which the streetlights are turned on or off automatically at regular time or a control mode in which the streetlights are turned on or off automatically based on the ambient light condition; however, vehicles do not enter the tunnel all the time in respect of some road segments, so there will result in a waste of energy if the tunnel is kept bright all the time. In addition, environmental condition control devices such as exhaust fans would also be arranged within the tunnel besides necessary lighting fixtures in order to maintain the required air quality in the tunnel; similarly, there will also result in a waster of energy during the low traffic volume time period if such environmental condition control devices are operated in a manner of being turned on or off automatically at regular time. If they are operated manually, then there will incur considerable labor cost and it might be impossible to monitor the environmental condition of the light 1 fixture location as desired due to human negligence likely to occur. Summary of the Invention In view of the above, the main object of the present invention is to provide an environmental monitoring system capable of monitoring the surrounding environmental condition of each light fixture by a remote host. To this end, the environmental monitoring system of the present invention is integrated with at least one environmental detector, a remote host and at least one light fixture; the remote host having a monitoring software built therein and electrically connected with a first wireless transmitting/receiving module and a first power amplifying module for amplifying a signal wave transmitted outward by the first wireless transmitting/receiving module; each light fixture is provided in the body thereof with an AC-DC converter for a connection with a power source, a photoelectric module, and a controlling circuit electrically connected between the AC-DC converter and the photoelectric module, respectively; wherein the controlling circuit of each light fixture is further integrated with: a second wireless transmitting/receiving module electrically connected with the AC-DC converter for performing signal transmission/reception with the remote host; a power amplifying module electrically connected with the second wireless transmitting/receiving module for amplifying a signal wave transmitted outward by the second wireless transmitting/receiving module to obtain a required transmission distance; a signal processing module electrically connected with the second wireless transmitting/receiving module for receiving a signal detected by the corresponding environmental detector and transmitting the identified and confirmed signal to the wireless transmitting/receiving module for outward transmission; and a signal transmitted by each light fixture is received by the first transmitting/receiving module of the remote host and the received signal is analyzed and compared by the monitoring software to obtain the surrounding environmental condition of each light fixture.

Each light fixture can be reversely controlled by the remote host to turned on, off or dim. Detailed Description of the Preferred Embodiments The features of the present invention can be explicitly illustrated with reference to the drawings and description of the embodiments. As shown in Fig. 1 which is the configuration reference diagram of an environmental monitoring system of the present invention, an environmental monitoring system of the present invention consists of at least one environmental detector 10, a remote host 20 and at least one light fixture 30; wherein the at least one environmental detector 10 may be one of a CO 2 concentration detector, an object proximity detector or a vehicle speed detector; a detected signal transmitted by the at least one environmental detector 10 is first received by the light fixture 30 and identified and confirmed by the same, and then transmitted outward in a wireless transmission manner to be received by the remote host 20 so that the remote host 20 can monitor the surrounding environmental condition of each light fixture 30, and so much so that the remote host 20 can further control the surrounding environmental conditions of light fixture 30 (for example: turning on the exhaust devices or light fixtures, or dimming the light fixtures etc.). 4 Referring to Fig. 2, the remote host 20 has a monitoring software 21 built therein and is electrically connected with a first wireless transmitting/receiving module 22 and a first power amplifying module 23 for amplifying a signal wave transmitted outward by the first wireless transmitting/receiving module 22; in practice, the first wireless transmitting/receiving module 22 has an IEEE interface built therein, and the first power amplifying module 23 has an amplifier built therein for amplifying a signal to be transmitted to the first wireless transmitting/receiving module 22. Each light fixture 30 is provided in the body 31 thereof with an AC-DC converter 32 for a connection with a power source, a photoelectric module 33, and a controlling circuit electrically connected between the AC-DC converter 32 and the photoelectric module 33, respectively; wherein the controlling circuit 34 of each light fixture 30 is further integrated with: a second wireless transmitting/receiving module 341 electrically connected with the AC-DC converter 32 for performing signal transmission/reception with at least one corresponding external remote host 20; in practice, the second wireless transmitting/receiving module 341 has an IEEE interface built therein for performing signal transmission/reception with the first wireless transmitting/receiving module 22 of the remote host 20. A second power amplifying module 342 electrically connected with the second wireless transmitting/receiving module 341 for amplifying a signal wave transmitted outward by the second wireless transmitting/receiving module 341 for obtaining a required transmission distance; in practice, the second power amplifying module 342 has an amplifier built therein for amplifying a signal to be transmitted to the second wireless transmitting/receiving module 341 for obtaining a required transmission distance. A signal processing module 343 electrically connected with the second wireless transmitting/receiving module 341 for receiving a detected signal from the corresponding environmental detector 10 and transmitting the identified and confirmed signal to the second power amplifying module 341 for outward transmission. In general, when the environmental monitoring system of the present invention is in use, the photoelectric module 33 of each light fixture 30 can be electrically connected with predetermined amount of light emitting diodes, fluorescent tubes or mercury lamps and connected with an external power source through the AC-DC converter 32; a power required for operating the photoelectric module 33 and the controlling circuit 34 is provided from the AC-DC converter 32 and after the photoelectric module 33 is in operation, a predetermined lighting effect can be achieved from the photoelectric module 33. 5 Especially, the signal processing module 343 regularly receives the detected signal transmitted outward by the surrounding environmental detector 10; and the detected signal, after being identified and confirmed, is transmitted to the second wireless transmitting/receiving module 341 and then transmitted outward through the second wireless transmitting/receiving module 341 to be received by the first transmitting/receiving module 22 of the remote host 20, so that the remote host 20 located relatively far away can receive the environmental detected signal in real time to achieve the purpose of monitoring the surrounding environmental condition of each light fixture 30 and so that the remote host 20 can further control the surrounding environmental condition of each light fixture 30. For example, when the light fixture is arranged within a tunnel and its corresponding environmental detector is a kind of CO 2 concentration detector for detecting the CO 2 concentration in the air, then the CO 2 concentration signal detected by the environmental detector can be transmitted to the remote host located relatively far away through the light fixture; and the remote host monitors the CO 2 concentration in the tunnel in real time, so that when the CO 2 concentration reaches a default value, the remote host can cooperate in reverse control of the exhaust device located in the tunnel, which improves the air convection effect and decreases the CO 2 concentration in the tunnel so as to achieve the purpose of controlling the surrounding environmental conditions of the light fixtures. When the light fixture is arranged within or at the entrance to the tunnel and its corresponding environmental detector is a kind of object proximity detector, the signal detected by the environmental detector can be transmitted to the remote host located relatively far away through the light fixture, so that the remote host monitors whether there is a vehicle entering the tunnel in real time; and while the vehicle is in the state of entering the tunnel, the remote host can cooperate in reverse control of turning on or dimming the light fixture within the tunnel; moreover, the remote host can receive the detected signal from the surrounding environmental detectors (object proximity detector) associated with other light fixtures within the tunnel or light fixtures located at the exit of the tunnel and determine whether the vehicle passes through the tunnel so that after the vehicle has passed through the tunnel, the light fixtures within the tunnel are turned off or dimmed to save energy. When the remote host determines that the signal from the environmental detector (object proximity detector) within the tunnel or on general roads is intermittent, it can be further determined that there is a breakdown of a vehicle or a vehicle accident so that relevant departments can be informed effectively for the check at the accident scene or providing assistance so as to avoid a bigger hazard. When the light fixture is installed within the tunnel or on general roads and corresponding environmental detector is a vehicle speed detector, it can cooperate with the remote host to detect whether there is a speeding or recklessly driven vehicle, so that the remote host can 6 effectively inform relevant departments for the check or ban at the scene so as to avoid a bigger hazard. Furthermore, as shown in Fig. 3 which is a block diagram showing the basic configuration of an environmental monitoring system of a second embodiment of the present invention, the controlling circuit 34 can be further integrated with: a dimming module 344 electrically connected with photoelectric module 33 for controlling the voltage/current output to the photoelectric module 33 substantially with a transistor for controlling the magnitude of input voltage/current or a variable resistor built therein for controlling the magnitude of input voltage/current so that the photoelectric module 33 produces a dimming function with different luminance. A current/voltage stabilizing module 345 electrically connected between the AC-DC converter 32 and the dimming module 344, and substantially having an OVP voltage stabilizing loop and an OVP current stabilizing loop built therein; in practice, the current/voltage stabilizing module 345 can be further built therein with a PFC power compensation loop or an OHP over-temperature protection loop, or further built therein with a PFC power compensation loop and an OHP over-temperature protection loop, so as to provide a stabilized power supply for the photoelectric module 33. A current/voltage detecting module 346 electrically connected between the second wireless transmitting/receiving module 341 and the current/voltage stabilizing module 345 for detecting the voltage/current information output to the photoelectric module 33 so that the detected voltage/current information is transmitted outward by the wireless transmitting/receiving module 341. And, the signal processing module 343 is further used for identifying and executing the signal received by the second wireless transmitting/receiving module 341. The current/voltage detecting module 346 can regularly detect the voltage/current information output to the photoelectric module 33 so that the detected voltage/current information is transmitted outward by the second wireless transmitting/receiving module 341 to the corresponding remote host 20, that is, the remote host 20 can obtain the on/off state of the photoelectric module 33 of the light fixture 30 via the received voltage/current information, and determine whether the photoelectric module 33 of the light fixture 30 is operated normally and further calculate the operating hours of the photoelectric module 33. Moreover, the remote host 20 can transmit related control signals to various light fixtures 30 for the purpose of remotely monitoring the same. Therefore, the environmental monitoring system is particularly suitable for the lighting fixtures (like streetlights) which are installed far away in a wide area from the managing unit, or applied to the lighting fixtures that are installed in a dangerous environmental condition. 7 It is appreciated that the light fixtures of the present invention may be arranged in a open place, so the light fixtures can be further electrically connected with a lightning strike protection module 35 in front of the AC-DC converter 32 as shown in Fig. 4, and connected with an external power source through the lightning strike protection module 35; in practice, the lightning strike protecting module 35 can be built therein with a discharge prevention assembly which discharges a strong current due to the forward lightning strike, so that when struck by lightning, the light fixtures can be protected against the damage caused by the lightning by conducting the strong current to the ground to effectively absorb the same. Compared with the prior arts, the environmental monitoring system of the present invention can not only manage the environmental conditions of the arrangement location of each light fixture in a relatively more active manner for promoting the remote host to further monitor the environmental conditions of the light fixtures, but also manage the operation state and maintain the regular operation of the light fixtures in a relatively more active manner; especially, various light fixtures can be reversely turned on or off or dimmed by the remote host to improve the driving safety on the roads (or in the tunnel) and achieve the effect of energy conservation and carbon emission reduction. In sum, the present invention is to provide an environmental monitoring system to seek a patent protection.
