With the rapid development of China’s economy and the rapid popularization of automobiles, fully automatic car washing machines become more and more popular with car owners because of their intelligent, fast, and 24-hour service characteristics.
Automatic car washing machine is a high-value automation equipment, discretely distributed in various areas of the city. It has the characteristics of many types of access equipment, many forms of communication interfaces, and many compatible communication protocols. How to effectively and remotely monitor the status of the automatic car washing machine, manage and control the safe and reliable operation of the automatic car washing machines, is a big challenge for the car washing machine operation companies.
As there are various video, image and data sensors are installed on the car washer, including cameras, temperature sensors, voltage sensors, pressure sensors, speed sensors, displacement sensors, laser sensors, etc. Through the HG462 edge computing gateway of HELIOS Technologies, a remote monitoring system is quickly set up to realize access to car wash sensor data, video images, sound, etc., remote monitoring, abnormal alarms, and equipment linkage greatly improve the efficiency of car wash management.
HG462 edge computing gateway, with rich interfaces, can provide one-stop access to sensors, meters, cameras, and PLC equipment. Interfaces include 1 LAN port, 1 WAN port, 3 RS232 (expandable to 4), 3 RS485 (expandable to 4), 1 SHT, 1 TTL level serial port, 4 digital inputs, 8 analog inputs, 4 relay outputs, 1 USB, etc., with rich acquisition control ports, the implementation is more flexible. 5-channel power output, convenient for sensor and camera to acquire power, greatly reducing deployment difficulty and saving project costs.
Parameters monitored include:
- License plate recognition: image collected and transferred through the gateway to the remote server for comparison, judging whether the vehicle is allowed to pass or not, and send commands to the car washing machine to execute the car washing process.
- Car washing machine motor running status monitoring: vibration (frequency, amplitude), temperature, current signals.
- Monitoring of car washing process: whether the operation logic is correct, car washing time is sufficient, and action is correct.
- Alarms of the car washing machine: including the alarm time, the location of the alarm that causes the failure, and the reason of the alarm.
- Monitoring of car washing machine fault maintenance information: including maintenance time, maintenance personnel, etc.
- Environment monitoring around the car washer, image information is stored locally, and can be uploaded to the cloud platform for emergency use.
- Basic information of car washing machine: including manufacturer, production date, running time, type, model, parameters, etc.
