How to integrate the HPC168 bus passenger counter with your system?
Our HPC168 bus passenger counter supports two communication protocols for integration.
1. When the bus has on-board network access, you can connect via RJ45 interface using HTTP protocol (TCP connection).
2. If no network is available, the passenger counter device needs to connect a GPRS module via RS485 interface using RS485 protocol. The RS485 protocol requires the server to actively query, and the queried data is the total number. When reading, the current time is directly recorded. For example, at 10:00, a read shows 10 people entering and 10 people exiting; at 10:05, a read shows 15 people entering and 15 people exiting. This is the data for those 5 minutes: 5 people entering and 5 people exiting. The maximum total number that the device can store in RS485 mode is 999,999. Please refer to the details of our two protocols for further information.
