Equipment safety control method based on multi-component electrical bindingTechnical Field
The invention relates to the technical field of engineering machinery control, in particular to a device safety control method based on multi-component electric binding.
Background
Engineering machinery equipment is usually sold in a financing lease mode, and a user purchases equipment to put into production to obtain income and then pays monthly installments. Before some users unpaid the loan, the vehicle-mounted communication terminal used for risk management by the dealer is dismantled, the insurance is avoided, and even the stealing equipment is transferred, so that huge loss is caused to the dealer.
And part of users use the equipment in order to achieve high-strength overload, avoid monitoring of the use condition of the equipment by a dealer, further avoid the responsibility of equipment damage caused by improper use, remove the vehicle-mounted communication terminal, illegally rewrite the controller program and bring after-sale risks to the dealer and a production enterprise.
In order to effectively control financial risks, after-sales claim liability is reasonably defined based on monitored data, and thus users must be prevented from privately removing, modifying the equipment electrical system.
In the prior art, a heartbeat signal is added in data communication between the vehicle-mounted terminal and the controller, and after the vehicle-mounted terminal is removed, the controller cannot monitor the heartbeat signal of the vehicle-mounted terminal. When the controller does not detect the heartbeat signal, the controller will limit the device power or work.
The user can destroy the monitoring of the vehicle-mounted terminal by the following methods and normally use the equipment:
(1) after the terminal is removed, the controller can still normally operate by imitating heartbeat signals.
(2) Flash the controller program or replace a new controller without heartbeat detection mechanism (illegal source).

step two: after the device in the network receives d (a), verifying whether a is the same as the stored binding password, and if so, unbinding;
step three: when the equipment in the network is damaged, replaced and removed, all the equipment needs to be unbound first, and the equipment needs to be bound again after the new equipment is replaced;
step four: when the display is damaged, the display needs to be replaced by a new display, binding is executed, and the original binding password is input to finish binding; and if other equipment needs to be replaced, the display binding is finished and then the display binding is executed according to the third step.
Preferably, in step three, when the device in the network is damaged, replaced or removed, the device does not include a display.
Preferably, the engine control module controls engine start, air intake, fuel injection, speed and obtains engine operating parameters through sensors in the engine.
Preferably, the controller is used for controlling an electrical system, a power system and a hydraulic system of the equipment and driving core components of the equipment to move and work.
Preferably, the display displays the operating state of the device, the fault information, and the blind area image, and can set the device parameters or the operating mode by touching or a mechanical keyboard.
Preferably, the vehicle-mounted communication terminal is communicated with the equipment management platform and has the functions of equipment data acquisition, positioning, remote supervision and remote control.
The invention has the beneficial effects that:
the multiple devices are bound, so that any one electrical component cannot be normally operated when being detached, replaced and damaged, and the monitoring capability of manufacturers and distributors on the devices is enhanced unless all the electrical components are replaced, and the cost of breaking a monitoring system and an electrical system in violation of rules of a user is increased.
The operation of the electric binding is controlled by the manufacturer, so that the control force of the manufacturer on replacement of spare parts is strengthened, the application management of original factory parts is improved, and the problem of equipment abnormity caused by using non-original factory parts by customers is reduced.

Detailed Description
The present invention will be further described in detail with reference to the following drawings.
A device security control method based on multi-component electrical bundling, the method comprising bundling;
the binding method comprises the following steps:
the method comprises the following steps: inputting a string of binding passwords through a display, wherein the passwords are character strings a, and broadcasting information f (a) to all equipment in a network by the display after selecting to execute electric binding, wherein f is a binding operator;
step two: after receiving broadcast information, the engine control module, the controller, the vehicle-mounted communication terminal and the equipment N store the binding password a and broadcast successful storage information save (id), wherein the id is address codes of all equipment in a network;
step three: after receiving the successful storage information of all the devices, the display broadcasts the successful binding information success (a) to all the devices in the network and stores the network address tables of all the devices in the network;
step four: and after the engine control module, the controller, the vehicle-mounted communication terminal and the equipment N receive success (a), storing network address tables of all equipment in the network.
Step five: the binding takes effect.
After binding is successful, each device broadcasts the network address and the binding password to the network and receives the broadcast information of other devices when the system is started each time. When one device can not successfully receive the network addresses and the binding passwords of all other devices in the system, the abnormal information is broadcasted to the system, and all the devices receiving the abnormal information enter an abnormal state.
Further scheme: in step one, a string of binding passwords is input through a display, and the password is a character string which is not 0.

step two: after the device in the network receives d (a), verifying whether a is the same as the stored binding password, and if so, unbinding;
step three: when the equipment in the network is damaged, replaced and removed, all the equipment needs to be unbound first, and the equipment needs to be bound again after the new equipment is replaced;
step four: when the display is damaged, the display needs to be replaced by a new display, binding is executed, and the original binding password is input to finish binding; and if other equipment needs to be replaced, the display binding is finished and then the display binding is executed according to the third step.
