A grid gateway and a transmission tower management system having a plurality of the grid gateways are disclosed. The grid gateways are connected with one another to form a mesh network. A plurality of sensors are provided within a wireless transmission range of the grid gateways. The sensors collect and send environmental parameters to the corresponding grid gateway within the wireless transmission range, in order to choose an optimal transmission path in the mesh network through grid gateways to transmit. The environmental parameters are transmitted through the optimal transmission path to a server for storage and analysis. A grid gateway and a transmission tower management system having a plurality of the grid gateways have broad and local area wireless transmission ability, so as to overcome restrictions of topography and communication to execute broad area management and monitor tasks.

A multi-checkpoint type clustered animal counting device is proposed, which is capable of providing a counting function that can be used for statistically determining the number of animals (such as fruit flies) within a region such as farmland or garden. The proposed animal counting device is characterized by the utilized to at least two object sensors, wherein the first object sensor is disposed at a first checkpoint while the second object sensor is disposed at a second checkpoint, and wherein the first object sensor is initially set to power-on state while the second object sensor is initially set to power-off state and can be switched on only when the first object sensor is triggered. When the second object sensor is triggered, the counting operation will increase the output count number by one. This feature allows a more accurate result and can help save power consumption.

A front-end gateway unit is designed for integration to a remote ecological environment monitoring system that is equipped with a wireless sensor network (WSN) system installed at a remote site, such as a farmland or a garden, for the purpose of allowing the WSN system to exchange data with a back-end host server via a wireless communication system. The front-end gateway unit is characterized by the capability of using either the WSN system or a built-in sensing module for collecting ecological data, and the capability of combining geographical location data in the ecological data. This feature allows the collection of a comprehensive set of ecological data (including geographical location, temperature, humidity, sunlight data, wind speed, and pest number) for transfer to the back-end host server, such that research/management personnel at the local site can conveniently browse these ecological data and learn the ecological conditions of the remotely monitored area.

A wireless-linked remote ecological environment monitoring system is proposed, which is characterized by the use of a sensor network such as WSN (wireless sensor network) installed at the remote site for collecting ecological data, and the use of a public wireless communication system such as GSM (Global System for Mobile Communications) for transferring all the collected ecological data to a back-end host server unit where the ecological data are compiled into webpages for posting on a website. This feature allows the research/management personnel to browse the ecological data simply by linking a network workstation via a network system such as the Internet to the website, without having to travel to the remote site and collect ecological data by human labor.

Wireless-linked remote ecological environment monitoring system

A wireless sensor network gateway unit is proposed, which is designed for integration to a wireless sensor network (WSN) for providing a gateway function with a failed link auto-redirecting capability for the wireless sensor network. The proposed WSN gateway unit is characterized by the provision of an failed link auto-redirecting capability, which can respond to the failure of any sensor node in the WSN system by performing a failed link auto-redirecting operation for redirecting the down-linked good sensor nodes for linking to a nearby good sensor node to thereby allow the down-linked good sensor nodes to be nevertheless able to transfer data to the WSN gateway unit of the invention. This feature allows the WSN gateway unit of the invention to maintain good operational reliability for the WSN system.
