Abstract
An air brake monitoring system for monitoring a pressure of the system and providing various alarms and/or warnings to a user including tire and brake status/alarms and providing for a backup alarm. The air brake monitoring system configurable to function with the existing wiring of the vehicle and including an air brake monitoring device to be positioned in the vicinity of a brake valve. The air brake monitoring system is further provided to monitor the electrical stoplight power transmitted to the ABS brakes as well as the vehicle static/dynamic condition.
Claims16
A brake monitoring system comprising:
- a service/control pressure line;
- an emergency/supply pressure line;
- a brake valve coupled to a brake actuator and operating the brake actuator, said brake valve coupled to the service/control pressure line and the emergency/supply pressure line, the service/control pressure line and the emergency/supply pressure line each being configured to provide pressurized air to the brake valve;
- a brake monitoring device having a processor and coupled to the service/control pressure line and the emergency/supply pressure line, the monitoring device monitoring the pressure of both the service/control pressure line and the emergency/supply pressure line;
- said processor comparing the measured pressure of said service/control pressure line and said emergency/supply pressure line to a pressure set point;
- and
- said brake monitoring device generating an indication based on the measured pressure;
- said indication is transmitted as:
- a hard-wired data connection, a wireless transmission, an electrical power line connection or combinations thereof,
- said indication presented as either an alarm, or a warning lamp, or a message, or combinations thereof.
A brake monitoring system comprising:
- a service/control pressure line;
- an emergency/supply pressure line;
- a brake valve coupled to a brake actuator and operating the brake actuator, said brake valve coupled to the service/control pressure line and the emergency/supply pressure line, the service/control pressure line and the emergency/supply pressure line each being configured to provide pressurized air to the brake valve;
- a monitoring device having a processor and coupled to the service/control pressure line and the emergency/supply pressure line, the monitoring device monitoring the pressure of both the service/control pressure line and the emergency/supply pressure line;
- wherein said monitoring device is coupled to a measurement device and said processor compares the pressure in the emergency/supply pressure line and the service/control pressure line to a set point and said monitoring device generates a warning indication for at least one of the following conditions:
- brake drag warning, emergency/supply pressure line warning, service/control pressure line warning, loss of stoplight power warning, incorrect state of trailer glad-hand shut off valves warning, incorrect dolly connection warning, incorrect air connection warning, closed brake valve warning, incorrect vehicle static/dynamic condition, tire pressure warning, tire temperature warning, tire inflation warning, brake temperature warning, and brake stroke warning;
- said indication is transmitted as:
- a hard-wired data connection, a wireless transmission, an electrical power line connection or combinations thereof,
- said indication presented as either an alarm, or a warning lamp, or a message, or combinations thereof.
