The distinctive feature of the Montrans M-5 Wi-Fi controller is offline operation with the ability to transmit information via Wi-Fi and create an access point to receive data from other terminals to send to the server, to the transport monitoring system. It is designed to work on hard-to-reach objects, in places with poor cellular communication, or with a complete lack of GSM coverage. This allows to reduce the cost of specialized equipment, in particular, expensive satellite communication. Montrans M-5 Wi-Fi can work in parallel with two CAN-buses, transmit data from sensors not only by supporting RS 485, RS 232, 1-Wire protocols, but also via Bluetooth 5.0 interface. Technical specification - Analog sampled and pulse-frequency inputs: 6 - Transistor outputs: 4 - Digital inputs RS 485: 1 - 1-Wire digital inputs: 1 -CAN inputs: 2 - RS 232: 1 Montrans M-5 Wi-Fi controller automatically accumulates information from all adjacent terminals, and returning to the GSM cellular coverage area transmits data to the vehicle monitoring system. The change of modes of collecting and sending information is automatic with the help of polygonal geo-fences and GSM or Wi-Fi signal level at a specified time interval. To ensure data safety in case of 2G/3G/LTE/Wi-Fi network failure, the terminal has internal non-volatile flash memory, as well as the ability to customize data storage on microSD card. Result of implementation of the Wi-Fi monitoring system - Controlling the operation and improving the efficiency of machinery operation; - control of fuel consumption and prevention of theft; - occasional lack of communication does not affect the completeness of the picture; - possibility of simultaneous data reception from 10 terminals; - possibility to upload data for a specific date range; - optimization of enterprise costs; - increasing the discipline of work of the company's employees.
