Vehicle Status Monitoring Solution In Truck Transportation

Vehicle Status Monitoring Solution In Truck Transportation

1. SPH3A0 series positive and reverse tachometric transduce is detected by Hall principle, which only needs to fix two corresponding magnets on the axis and  wheel  (two  magnets  are  distributed symmetrically, and the N pole of one magnet must face to the sensor, and the S pole of the other magnet must face to the sensor), and fix the arrow of the detection surface of the sensor probe to face the arc of the magnet rotation.

  When the wheel or axis rotates, the magnet sweeps the sensor probe along the direction of the arrow, Line 2(blue line) outputs positive rotation signal (low level), Line 4(white line) outputs positive rotation speed pulse signal; conversely, Line 2(blue line) outputs reverse rotation signal (high level), Line 4(white line) outputs reverse rotation speed pulse signal.

2. The load sensor SAHX-120B is designed according to the principle of angle measurement, because the change of vehicle load will lead to the deformation of leaf spring and produce displacement, and the change of vehicle weight can be monitored by measuring the displacement corresponding to the corresponding.

3. The  Oil level sensor SFP423 series pressure type,  liquid level sensor senses the linear change of the pressure formed by the height of the liquid and the oil level. It uses the principle that the semiconductor strain gauge undergoes a change in pressure to produce a resistance change, and converts the resistance signal into a standard electrical signal output, which can be directly displayed The height of the liquid level can be sent to the remote monitoring system via a wireless device.

The pressure type liquid level sensor can be used to accurately measure the oil level of automobile fuel tanks, tank cars, oil depots, etc. The whole machine has no movable or elastic parts, impact resistance, convenient installation, high reliability, high precision, and good cost performance. It is also suitable for the measurement and monitoring of various other liquids.

1. The above sensors are separate hardware devices; they can be used with terminal equipment and network platforms; the sensors are responsible for collecting data and sending it to the monitoring platform (such as ERP system) through the vehicle GPS/Beidou terminal equipment.

2. The sensor provides basic data, and the platform needs to filter, analyze, and process the data to implement various applications.

3. For users who do not have GPS installed, a transmission module can be installed to collect the data on the office management platform
