Description
Technical Field
the utility model relates to a three-roller gate machine.
background
At present, the main application modes of the three-roller gate are as follows: after the access controller judges the passing authority of the passing personnel, a gate control unit in the gate opens a mechanical locking structure of the three-roller gate to allow the personnel to pass. The general procedure is as follows:
Firstly, a passer-by carries out face recognition or other identity recognition through recognition equipment, and the recognition equipment transmits the recognized ID into an access controller;
Secondly, after judging that the ID is legal, the entrance guard controller sends a turn-on signal to the gate control unit, and the gate control unit controls the gate to be released;
and thirdly, the access controller sends the ID of the communication personnel to the background through network communication, and the background is used for counting the number of the passers.
However, the method can only count the passing according to the identification record, and a counting leak exists, for example, a passing person does not pass through the gate after being identified, and the background still judges that the person passes through the gate.
In many scenarios, it is necessary to confirm the actual number of people entering a certain enclosed area through a gate and have to exit the area within a certain time. For example, a worksite manager may need to confirm that workers entering a closed construction worksite on duty must all exit the worksite after work. This requires that the gate must be able to record the actual number of people passing through, or the count is meaningless.
The invention patent with the patent application number of CN201810201061.2 discloses a construction site attendance checking method, electronic equipment, a storage medium and a device, wherein an infrared detection area is formed by an infrared probe rod and a gate machine in the attached drawing of figure 3 of the patent specification, and the passage of detection personnel is detected. However, this method is complicated, requires multiple sets of probe rods, occupies a large area, and has a very high maintenance cost.
The invention patent with the patent application number of 201410378575.7 discloses a counting method and a device for a three-roller gate, wherein a metal proximity switch is additionally arranged at the tail end of an electromagnet of the three-roller gate, and the counting is realized by matching with a counting control board. When a person passes through the device, the brake lever is pulled, the bump on the claw wheel pushes the stop block and the connecting rod, the proximity switch sends out a signal after detecting the connecting rod, and then whether the person passes through the device is comprehensively judged according to the signals on the two sides. However, in this method, the rotational positions of the pawl wheel and the brake lever are indirectly determined by the position of the electromagnetic lever link, and it is not possible to directly detect whether the brake lever has been successfully indexed. If the passer-by exits the gate back again after pushing the gate lever halfway, the proximity switch signals, the gate still assumes that the passer-by has passed, resulting in inaccurate counting.

as shown in fig. 1, the states of two sets of magnetic switches 3 in the gate machine have four conditions:
The first condition is as follows: the first switch is closed, the second switch is opened, and the movement 1 is shown in a first rest position;
Case two: the first switch is closed, the second switch is closed, and the movement 1 is shown in a second rest position;
Case three: the first switch is turned on, the second switch is turned off, and the movement 1 is shown in a third rest position;
Case four: the first switch is turned on, and the second switch is turned on, which indicates that the movement 1 is rotating and does not reach any rest position.
the counting function of the gate judges the state of the movement 1 based on the four signal combinations, and then judges whether the current transposition is carried out or not, whether the transposition is successful or whether the movement exits during the transposition. As shown in fig. 4, the access controller 7 has the following determination method:
A. and detecting the states of the two groups of magnetic control switches 3, if the two groups of magnetic control switches 3 are both opening signals, which indicates that the current movement 1 is rotating and does not reach any rest position, continuously and circularly detecting the signals of the two groups of magnetic control switches 3 until at least one of the two groups of magnetic control switches sends a closing signal, which indicates that one rest position is reached currently. Recording the signal states of the two groups of magnetic control switches 3 at present, and recording as a first state;
B. Continuously detecting the signal state of the magnetic control switch 3;
C. If at least one of the signal states of the two groups of magnetic control switches 3 sends a closing signal, which indicates that the current movement 1 does not rotate, returning to the step B to continue the detection; if the signal states of the two groups of magnetic control switches 3 are both opening signals, which indicates that the current movement 1 starts to rotate, the step D is carried out;
D. Waiting for the signals of the two groups of magnetic control switches 3 to change, recording the state of the magnetic control switches 3 after the change, and recording as a second state;
E. comparing whether the first state and the second state are consistent: if the two states are not consistent, the brake lever is indicated to pass by, the passing success record is transmitted to the background server 8, the second state at the moment is recorded as the first state, and then the step B is returned; if the two are consistent, the fact that the person pushes the brake lever to withdraw halfway again indicates that the movement 1 returns to the original position, and the step B is directly returned to at the moment without counting and recording.
The above steps are only used for counting and determining when to open and close the locking mechanism is another program control of the access controller, and the specific principle is referred to in the foregoing, and will not be described in detail herein.
