The energy-saving controller controls the engine speed and locks the engine speed at a low speed position. Work in a powerless state; when executing the secondary lock command, the GPS vehicle terminal controls the relay to cut off the starting circuit and lock the excavator.

The device is mainly composed of two parts: vehicle hardware entity and network transmission and management;

1. Vehicle-mounted hardware entities, including multi-function monitors, GPS vehicle-mounted terminals, energy-saving controllers, engine starter motors, and accelerator mechanisms;

GPS vehicle terminal hardware description:

1. Power supply: The power supply part provides +5V and +3.3V required by the system, and its PWR_IN+ and PWR_IN- are the positive and negative poles of the external power supply. The power supply part can also automatically switch the input source to an external power supply or a battery according to the power supply of the external power supply.

2. Battery charging part: The main function of this part of the circuit is to charge the battery and stop charging after it is fully charged. It also detects the charging and discharging current of the battery and protects the battery.

3. Relay and switch part: This part of the circuit is mainly used to control the lock and detect whether it is disassembled.

4. GPS and GPRS module: The GPS module is used to measure the current latitude and longitude of the machine, and the GPRS module is used to connect the received data to the INTERNET network through the GPRS gateway for data communication with the monitoring server.

5. CPU: Control the whole machine.

6. RS232 interface: Communicate with an external multi-function monitor through RS232 level conversion, used to collect excavator data and send control commands.

2. Network transmission and management system, monitoring server, client terminal, wireless data communication network and other parts.

The GPS vehicle terminal and the multi-function monitor are connected through the RS232 communication interface and some control lines for signal transmission. Mainly complete the following tasks:

1. On-line mode setting: Two working modes of the control system can be set in the multi-function monitor: GPS on-line mode and GPS off-line mode. The setting of the mode can be completed on the multi-function monitor, and can also be completed by remotely issuing instructions from the monitoring server. In these two modes, the system can upload the system operating parameters collected by the monitor to the GPS vehicle terminal, and the GPS vehicle terminal will package the parameters uploaded by the multi-function monitor and the location information of the machine and upload them to the client terminal for the user Check. The difference between these two modes is: in the GPS online mode, the system detects the connection between the GPS terminal and the system, and if the connection is not normal, the system will lock the machine. At the same time, in this mode, the user can remotely issue instructions through the monitoring server to make the system in a locked or unlocked state. In GPS offline mode, the above functions are not available.

2. Lock function: The system lock is divided into a first-level lock state and a second-level lock state. When the engine is locked at the first level, the GPS vehicle terminal sends a corresponding command to the multi-function monitor through the RS232 communication port. After receiving the command, the multi-function monitor sends an enable signal to the host energy-saving controller through the wiring harness, and automatically controls the engine speed at the idle position. , control the power of the main pump of the excavator to the minimum output power, and at the same time, the monitoring parameters are no longer displayed on the multi-function monitor, but a reminder message reminds the user to drive the excavator to a safe position and then shut down, waiting for unlocking. The second-level lock is based on the first-level lock, and the engine start control is added. When the engine is turned off after the lock, the engine cannot be started again. The unlocking operation after locking the machine can be completed by remotely issuing instructions from the monitoring server. It can also be done by entering the corresponding unlock password on the multifunction monitor.

3. GPS system dismantling detection and anti-dismantlement function: In the GPS vehicle terminal online mode, the system detects whether the GPS vehicle terminal connection is intact, mainly detecting the GPS vehicle terminal module system power connection, communication interface and antenna. If it is detected that there is a fault in the connection, the system will enter the first-level lock state.

4. Parameter upload: In this system, the GPS vehicle terminal transmits the data collected from the monitoring system through the RS232 communication port, and transmits the data to the monitoring server through GPS global satellite positioning system, GPRS/GSM network, Internet network and other wireless transmission systems , the monitoring center will classify and manage the received data according to the GPS number through the software platform of the monitoring server, and store the final data on the monitoring server in the form of pictures and texts. The administrator can easily query and obtain through the software platform The following parameters: working hours, air filter switch alarm status, oil pressure switch alarm status, hydraulic oil filter switch alarm status, cooling water temperature alarm status, engine speed, fuel oil level, oil pressure value, cooling water temperature, hydraulic oil temperature, machine The location information, the lock status of the machine, the power-on status of the machine, etc.
