Problems solved by technology

The inventor found in the process of realizing the present invention that the prior art cannot effectively prevent the GPS terminal from being dismantled
Although if the GPS terminal is directly removed, the relay will be normally closed and the engine will not work, but there are large loopholes in the conventional relay circuit, the user can still achieve the goal through some means: for example, directly supply power to the coil of the relay, so that the relay has power , the relay is always in the normally open state, so that the GPS terminal loses its control function and cannot control the engine to turn off; for example, if the relay is pulled out directly, the GPS terminal also loses its control function
It can be seen that the existing technology is easy to be cracked and cannot effectively prevent the GPS terminal from being dismantled

Embodiment 1

[0051] Mobile cranes are generally equipped with an electronically controlled engine (hereinafter referred to as the engine), and the engine is controlled by the engine ECU (Electronic Control Unit). The engine ECU controls the working state of the engine by collecting various sensor signals or bus data of the engine, such as controlling engine start, flameout, output speed, output torque, etc. The GPS terminal installed on the crane can not only send positioning information, vehicle speed information, engine operation parameters, and engine failure information to the GPS control center, but also receive remote commands such as locking the car from the GPS control center through the antenna.

[0052] figure 2 It is the electrical schematic diagram of Embodiment 1 of the present invention, including: battery 201 , power switch 202 , insurance 203 , GPS terminal 204 , and engine ECU 205 . Wherein, the storage battery 201 is connected to the GPS terminal 204 to provide long-ter...

Embodiment 2

[0062] Figure 4 It is a flow chart of the method in Embodiment 2 of the present invention. This embodiment is based on the first embodiment and is a further extension of the first embodiment. Include the following steps:

[0063] S401: Power on the engine ECU. Start this process.

[0064] S402: Read the current GPS terminal communication parameters through the bus. That is, the engine ECU obtains the communication parameters of the current GPS terminal through the bus. The communication parameters may include hardware parameters currently sent by the GPS terminal, first password information, and other instructions such as an instruction to unlock the car function. Of course, GPS may not be installed at present, and at this time, each item in the communication parameter is empty.

[0065] S403: Determine whether it has been bound with the GPS terminal. That is, the engine ECU judges whether it has been bound with a GPS terminal. For example, it judges whether it has pr...

Embodiment 3

[0079] Figure 5 It is a schematic diagram of the third device of the present invention, and the device includes:

[0080] A password acquisition unit 501, configured to acquire the first password information sent by the current GPS terminal;

[0081] A password checking unit 502, configured to judge the correctness of the first password information: if the first password information is not obtained or the obtained first password information is the same as the second password information pre-stored by the engine ECU If it does not match, a penalty unit is triggered, wherein the second password information corresponds to a designated GPS terminal, and the designated GPS terminal is a GPS terminal bound to the engine ECU;

[0082] The penalty unit 503 is configured to generate and store a vehicle lock instruction in the engine ECU, so as to perform a vehicle lock operation according to the vehicle lock instruction.

[0083]Preferably, it also includes:

[0084] The car lock j...

Abstract

The embodiment of the invention discloses a method, a device and a system for preventing disassembling of a global positioning system (GPS) terminal of a crane. The method comprises the following steps of: S1), acquiring first password information transmitted by the existing GPS terminal; S2) if the first password information is not acquired or the acquired first password information is not matched with second password information which is previously stored by an engine electronic control unit (ECU), entering a step S3), wherein the second password information corresponds to the designated GPS terminal, and the designated GPS terminal is the GPS terminal which is bound with the engine ECU; and S3), generating and storing a locking order in the engine ECU, so that the locking operation can be performed according to the locking order. Therefore, if the GPS terminal is privately disassembled or replaced, a password transmitted by the GPS terminal cannot be correctly read by the engine ECU, so that the vehicle is locked to punish users, and the private disassembling of the GPS terminal by the users can be effectively prevented.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a method, device and system for preventing dismantling of a GPS terminal of a crane. Background technique [0002] Cranes, especially mobile cranes, can flexibly transfer work sites and are widely used in petrochemical, metallurgy, construction and other fields. At present, many mobile cranes (hereinafter referred to as cranes) are purchased by mortgage. In this case, in order to protect the interests of banks or manufacturers, GPS (Global Satellite Positioning System) terminals are generally installed on the cranes. The GPS terminal can not only locate the crane 24 hours a day, but also has the functions of sending and receiving remote commands, communicating with various ECUs (electronic control units), and inputting and outputting. When the user (such as the purchaser or the leaser) fails to repay the mortgage loan, the authorized department such as the bank or the manufacturer can remo...
