Temperature and light control in the refrigerator
using the TL-BLE wireless sensor
Tasks of the client and the integrator
While transporting perishable products in refrigerators, it is always necessary to monitor the performance of refrigeration equipment and strictly observe temperature conditions. Deviations from the desired parameters lead to melting and damage to the goods. Naturally, this entails losses and negatively affects the business reputation of the supplier company.
Along with this, violations in the operation of the refrigeration unit reduce its service life, cause fuel overspending, lead to wear of the engine and compressor of the refrigerator. Also, companies that are engaged in the transportation of perishable goods are often faced with the negligent attitude of drivers to comply with climatic conditions and even with direct theft of goods on the way.
The integrator company offered a combined solution, including:
- GPS / GLONASS trackers for monitoring the location of objects;
- telematics sensors for monitoring the situation in the refrigerator truck;
- a monitoring platform with software modules that allow you to remotely monitor changes in the conditions of transportation of perishable goods, determine the causes of violations and respond urgently to emergency situations.
Trackers of the Teltonika brand were installed in the cabs of all cars. Inside the refrigerators themselves, temperature and light sensors Escort TL-BLE were installed, integrated with trackers. Together with a high level of accuracy and reliability, the advantage of the sensors is that they are wireless and transmit readings to the tracker via the Bluetooth LE radio channel.
Therefore, while installing the TL-BLE, it is not necessary to lay cables, they can be fixed in any place and, if necessary, change the location. The sensors are easily configured from a smartphone, are unpretentious in maintenance and work independently for up to 3 years from the built-in battery.
Equipment installation example
The function of configuring user notifications to email and phone allows you to take timely measures to correct the situation. Dispatchers and management immediately receive messages about violations of temperature parameters and about cases of opening the van outside the loading and unloading zones of goods.
Example of control in a satellite monitoring system
Due to the installation of TL-BLE sensors, the management of the trading company is now always aware of the conditions of transportation of perishable products, is able to quickly respond to deviations from the required temperature parameters and detect suspicious manipulations with the cargo.
For example, one of the first sensors that was installed as part of this project helped to prevent an attempt of stealing frozen fish by an unscrupulous driver. At night, the management received a message from the monitoring system that the light level in the refrigerator van increased – at an unplanned time and in an unplanned place. Having left to check the situation, the owner of the business found the driver who was transferring the cargo to another car. The theft was stopped, and the driver was dismissed.
