Specifically, the remote control system for the cold box switch lock provided in the embodiment of the present invention is configured to execute the remote control method for the cold box switch lock, and the same or similar technical means are adopted, so that the same technical effects can be achieved, and further description is omitted here.
The invention uses the intelligent medical cold box to lock the equipment to ensure the safety of the articles in the cold box through remote control after entering the transportation state, simultaneously performs Bluetooth pairing with the cold box through the mobile terminal, completes the locking and unlocking operation through related software application, and supports the realization of a method needing unlocking under certain emergency conditions in the transportation mode.
According to the embodiment of the invention, the cold box monitors the locking and unlocking command by subscribing the related subjects, so that the recorded locking and unlocking operation can be carried out when the cold box meets an emergency in a transportation mode, and the operation can be tracked.
At present, most of storage boxes or thermostats on the market are provided with no electronic lock device, and whether replaced objects exist in the transportation process can not be guaranteed, so that the intelligent medical cold box realizes that the cold box automatically closes and locks after the transportation mode is carried out, and the effect that the cold box can not be directly opened is achieved. But considering that there may be an accident during transportation that requires opening the cold box for the transfer of the goods. Adopt bluetooth to realize the switch lock control to the cold box, when allowing the operation of unblanking, carry out the record with switch lock operation record to the cloud platform.
The cloud platform server broadcasts the Bluetooth unlocking seed through an MQTT protocol, the Bluetooth unlocking seed in the embodiment of the invention is an unlocking password under Bluetooth connection, wherein the broadcast message theme is defined as follows:
/sys/${YourProductName}/broadcast/seed/#
format of the broadcast message:
{"id": "123456789", "data": {"seed": "12312"}}
broadcast frequency of broadcast message: for 1 day.
And the cold box subscribes the corresponding message theme, and after successful analysis, the Bluetooth unlocking seed is locally stored.
When the cloud platform server side through receiving cell-phone APP message, control the cold box and get into transportation mode and close the lock, wherein, the message theme defines:
/report/device/lock/${YourProductName}/${YourDeviceName}
the server sends the message in the format as follows:
{
"id": "123",
"data": {
"lock": true
},
"timestamp": 1507707025
}，
the remote locking operation of the cold box is realized through the codes, and the cold box is ensured to be in a closed state.
In the transportation process, when abnormal box opening application needs to be carried out by the mobile terminal APP, necessary description information needs to be filled, and then an unlocking command is sent to the cold box through the Bluetooth; remove APP when using restart every day, can reacquire the bluetooth seed of unblanking that has updated to the buffer memory is local, when using when sending the bluetooth order of unblanking, the cell-phone carries out the bluetooth with the cold box and matches, unblanks the operation.
The cold box receives a command to carry out verification and unlocking; after pairing is successful, when the cold box receives an instruction sent by the Bluetooth, firstly, judging whether the instruction is correct and the Bluetooth seeds are consistent through CRC (cyclic redundancy check), and then, unlocking a cold box lock; this bluetooth operation can be performed only when the cold box is in the transport mode, and the bluetooth unlock operation is not allowed in the non-transport mode.
And after the cold box is successfully unlocked, the description information and the unlocking result (the cold box lock state) are notified to the cloud platform for data updating and recording.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention; various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
