Detailed description of the invention
Fig. 1 is the circuit diagram of utility model one embodiment.
In figure, 1- plant-grid connection terminal, 2- magnetic switch, the outside 3- handheld device access terminal, 4- control chip, 5- electricity
Source circuit, 6- wireless communication module, 7- download interface.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The basic ideas of the utility model are: using 3.6V lithium battery as power supply, there are plant-grid connection terminals to facilitate electricity
Source access, uses STM32L1 series monolithic as main control chip, sends data to remote server at regular intervals, so
Single-chip microcontroller enters standby mode to reduce power consumption afterwards.By BC28 module (ultra-low power consumption wireless digital transmission module) to remote server
Well lid information is sent, selects magnetic switch as the state sensor for the open and close for judging well lid, when well lid is opened,
Single-chip microcontroller is waken up by magnetic switch, wirelessly uploads to remote server so that the information that well lid is opened be passed through.Design
RS485 interface accesses terminal as external handheld device, normally-open well lid when facilitating well lid administrative staff's external equipment.
A specific embodiment of the utility model is described below:
It is the schematic diagram of one specific embodiment of the utility model referring to Fig. 1, Fig. 1.Since control chip 1 is selected
STM32L151C8T6 single-chip microcontroller, wireless communication module 6 select BC28 module, they are all made of 3.3V power supply, so, this is practical
The novel lithium battery power supply using 3.6V is accessed by plant-grid connection terminal 1P4,3.6V is converted to 3.3V by voltage stabilizing chip,
The model SPX3819-3.3 of voltage stabilizing chip selects STM32L151C8T6 single-chip microcontroller conduct in order to reduce power consumption with saving space
Chip 1 is controlled, it is 32 MCU of the super low-power consumption of a Cortex-M3 based on ARM, and can select internal crystal oscillator is to be
System provides clock, and can configure its operating mode to reduce the loss of system.The transmission mode of data uses side wireless communication
Formula solves the confinement problems of installation in this way.Wireless communication module 6 selects BC28 module, passes through TCP mode and remote service
Device is communicated.Since system is powered using 3.3V, so external handheld device access terminal 3 selects RS485 interface, RS485
The chip used model MAX3485ESA of interface.Because whole system is usually in standby mode, being waken up just can be with
Work, so needing to design wake-up circuit, magnetic switch 2P5 and external handheld device access terminal 3P6 is system in figure
Wake-up circuit, when well lid closure, switch P5 is disconnected, and WKUP_PLS pin level is low level.When switch P5 is opened, due to
The magnet positions of magnetic switch 2 change so that magnetic switch acts, and magnetic switch 2 is closed, since WKUP_PLS needs an electricity
It is flat to arrive low process again from low to high, so needing a differential circuit, therefore C15 capacitor is added and is realized with R31 resistance.Hand
The wake-up mode principle of holding equipment is similar with magnetic switch, further, it is also possible to be waken up by the RTC quarter-bell inside control chip 1
System.
The utility model is communicated using communication, thus be can solve system problem difficult to install, is not required to
Telecommunication circuit is wanted to transmit data, without being bound to external environment, facilitates installation, while reducing workload.System uses
3.6V lithium battery is powered, and existing technological difficulties are low-power consumption problems.The utility model is by being in system usually
Standby mode reduces the electric energy loss of circuit, meanwhile, reduce the use of peripheral components.When system is in standby mode, electricity
The loss of energy is mainly derived from magnetic switch 2 shown in FIG. 1, since well lid is typically in closed state, so magnetic switch 2 selects
Closed type is selected, is closed in this way in well lid, quiescent current very little.When well lid is opened, electric current flows through the R30 resistance in Fig. 1, so
Its resistance value can be increased suitably to reduce loss, can guarantee that WKUP_PLS pin can generate rising while as long as increasing resistance value
Along.
The course of work of the utility model is described below:
After the utility model powers on, system starts carry out the transmission of data, and being sent rear system will enter
Low-power consumption mode, to reduce the loss of circuit.There are three types of system wake-up modes: the first, control 4 inside RTC quarter-bell of chip
Event wakes up, and can set the interval time of quarter-bell in a program, such as setting 3 hours, and system will be small 3 when well lid is not opened
When after wake up and the data of well lid are sent to remote server, go successively to standby mode after being sent completely.Second, well
Lid wakes up when opening, and when well lid is opened, the magnetic switch 2P5 in circuit shown in Fig. 1 will be closed (to be switched disconnected when well lid is closed
Open), pin WKUP_PLS will generate a rising edge pulse, by system wake-up, then according to whether accessing handheld device to sentence
Whether normally-open determine well lid, then transmits data to remote server.The third, can pass through lead for RS485 interface
It draws, WKUP_PLS will also generate a rising edge pulse when being inserted into handheld device, and system is waken up, and transmission data finish laggard
Enter standby mode.The data of the utility model are transmitted through the progress of the wireless communication module 6 based on BC28 module, using the side TCP
Formula is communicated with remote server foundation.
Use above specific case is illustrated the utility model, is merely used to help understand the utility model, and
Not to limit the utility model.Think of for those skilled in the art of the present invention, according to the utility model
Think, several simple deductions, deformation or replacement can also be made.
