After the key is verified to be qualified, the device is associated with the door unit, the communication link is communicated at the moment, the device sends an instruction to enable the door unit to enter a maintenance test mode, meanwhile, the door unit can inform an industrial personal computer inside the equipment that the industrial personal computer is switched to a wireless maintenance test mode, at the moment, the upper computer can default the door unit to be offline, and the whole equipment enters a maintenance mode. After the device sends an instruction in a maintenance test mode to enable the door unit to complete various debugging, testing and overhauling works, a current communication link can be disconnected through a built-in program of the device, the door unit is restarted and brought on line through the built-in program after disconnection, an industrial personal computer in the equipment is informed that the industrial personal computer is switched to a working mode, and the industrial personal computer receives control of the upper computer again.

The specific transceiving process of the device follows the related protocols of wireless communication (including conventional protocols such as addressing, handshaking, communication and communication), and the following working modes are provided:

(1) self-diagnostic mode

In this mode, the device can send various test instructions to the gate unit connected with the current wireless communication link, read various hardware information of the gate unit, such as a driver serial number of the gate unit, a GCU board card number, embedded software version information, a current working mode, a preset value of a motion parameter and the like, and then enter a test mode, and after the device sends test execution to the gate unit in this mode, the device can monitor the test execution condition of the gate unit in real time, read and record the test execution result. And then comparing and judging by combining the embedded software version information, the current working mode and preset values of the motion parameters which are read before, checking whether the door unit is in a normal working state, if not, prompting corresponding information on the display module, then judging the cause of the fault, further communicating with the door unit again through a fault point detection instruction in the test case set, checking the fault point (which can be semi-automatically or manually operated) until the fault point is confirmed and repaired, and then restarting and observing whether the fault point is restored or recovered to the normal working state through hardware. (referring to the manual maintenance and repair process, the device plays a role in the link to replace the original troubleshooting process of wired connection with equipment through an engineering notebook).

(2) Remote video-assisted diagnosis

When the technical level that the fault point can not be found in the last step or the maintenance personnel who hold the device is limited, if the primary engineer can not judge the fault reason, clear video recording can be collected under any environment by the equipment through the camera and the light filling lamp, the video recording is sent to the maintenance center, the fault reason can be judged by the assistance of the maintenance center, at the moment, the device can be used as a video communication device, the communication between the field engineer and the maintenance center is ensured in real time, and the field engineer can obtain remote support conveniently, as shown in fig. 5.

After the maintenance center judges the fault problem, the maintenance center can send the solution to the device, and a field engineer can know the corresponding solution in the device and check and maintain the faulty door unit by means of a maintenance instruction set integrated in the device. This is why there are the camera, fill light, light sense return circuit, volume control and loudspeaker, the reason of the function hardware of group battery in this device too.

The control panel of the door unit of the device has a memory function, and the action process of the door unit is controlled by several motion parameters, including but not limited to: the door unit comprises an initial position, door opening and closing speed, hitting force, locking force and the like, in the process of mass production, each door unit has certain difference in motion parameters due to slight differences of materials, machining process errors, assembly and the like, and in order to achieve the motion performance consistency of all the door units, the motion performance parameters which are most suitable for application need to be selected in the debugging process. According to previous debugging and production experience, although the motion parameters of each door unit are different to a certain extent, a reasonable threshold range is generally available. During maintenance and detection, the device can read the motion parameters in the control panel, compares the motion parameters with a reasonable threshold interval, and indicates that the door unit has a fault if the current motion parameters are not in a reasonable range.

In addition, a certain dial switch is preset on the door unit control panel to determine the working state of the door unit, which are also working condition parameters of the door unit, and the instruction set of the device can read the settings through port detection and testing and judge whether the current working state of the door unit is consistent with the preset value.

For example, the following steps are carried out: when a certain gate channel encounters sudden power failure of a station in work and a standby generator set is not normally involved, gate equipment is abnormally closed, and after the gate channel is electrified, the gate unit is found to be abnormal in action. The conventional maintenance scheme is to disassemble the casing of the gate machine, connect the serial port of the gate unit control panel with a notebook, and read the parameters. After the device is used, the door unit can be directly accessed through modes such as Bluetooth, wireless communication and the like, and parameters are read. In any method, the initial position of the gate unit is lost due to abnormal power failure, that is, the parameter of the motor motion origin is lost. The device can directly set the initial movement position of the door unit, and if a conventional scheme is adopted, the notebook computer can send an initial position resetting and setting command to the door unit through serial port communication.

On the other hand, when a fault occurs, the main control board of the door unit records and reports a corresponding fault code, such as motor stalling, error reporting of a certain sensor in the traffic logic, and the like, and generally when the fault occurs, the door of the gate is required to be opened to observe whether the nixie tube on the main control board displays the corresponding error code. After the device of the utility model is adopted, the device can actively read after the door unit is in wireless communication link, or the door unit uploads the error code to be fed back to the device, then the device of the utility model can analyze the error code and automatically provides a corresponding further elimination scheme or a hardware diagnosis method, maintenance personnel can select the corresponding scheme on the device, and further drives the door unit to carry out case testing or self-resetting through the further communication interaction of the device and the door unit, when the door unit is driven to carry out case testing, the device replaces the original function of an upper computer, can send various testing instructions to the door unit and monitor whether the detection door unit can normally respond and correctly execute cases, once the device can not respond and completely execute cases, relevant error information can be displayed on the device, and locating the fault point through the use case. Use the utility model discloses when device drive door unit self resets, this device can send the reset instruction to the door unit to whether monitoring inspection door unit can normally carry out self reset function, and whether connect door unit once more after the reset and confirm whether recovered normal operating condition after its reset.

The above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same, and those skilled in the art can modify or equally replace the technical solutions of the present invention, and the protection scope of the present invention is subject to the claims.
