Belmont / Kilkerran / Corton Axle Counter Monitor

This website has been developed to monitor the status of the 2 main relays of the belmont axle counter system during the soak test

There are 2 Main sections of this site, live status and Events.
Live status should show the current state of both the TSR and TZR relay, this page updates automatically every second, a HIGH status on the TSR indicates that the track section is CLEAR. The TZR relay is the opposite function of the TSR
The events page shows historical information of the TSR and TZR relays being monitored by this system

The system uses MQTT protocol to transmit the relay information to an MQTT broker, the 'broker' then saves the information in a database, this website provides access to the information stored in the database
The system consists of a Raspberry Pi3 Located at belmont with a 3g modem fitted to provide communcations
The broker server is a Raspberry Pi4, this Raspberry Pi 4 also hosts the MySQL database server and the web server where this website is running
